Integrated Automotive Controls for H1 and MP1 Single Pumps
General information
Automotive controls description
The Integrated Automotive Control solutions are designed to support single path hydrostatic
transmissions systems consisting of one pump (available sizes: MP1 28-45cc and H1P 45-250cc) and one
or more hydromotor. Danfoss offers several software configurations to cover the application demands.
With the pre-installed application software and easily changeable control parameters, it is possible to
tailor the vehicles driving behavior to the individual requirements of the customer. The Semi-AutoCalibration function for the pedals and a Quick-Start Guide with implemented Hyperlinks in the Service
tool will make changes and tuning more easily and effective.
Targeted applications
Automotive controls for H1 and MP1 pumps are targeted for the following applications.
Wheel loader
•
Telehandler
•
Dumper
•
Sweeper
•
Snow blower
•
Forestry machines
•
Hydrostatic propel methods
The application software offers different hydrostatic propel methods (defined as mode types).
Up to 4 system modes can be defined individually by parameter.
Automotive transport mode
Proportional pump and hydromotor displacement control.
The setpoint of the pump and hydromotor drive curves are given by the engine rpm. The engine rpm is
commanded by a drive pedal.
•
Drive pedal controls engine rpm
•
Engine rpm controls vehicle speed
•
Load dependent mode
•
Brake/inch signal reduces vehicle speed
•
Coast down when the drive pedal is released
Automotive ECO mode
The ECO fuel saving mode is designed for the Automotive Transport mode. It needs a CAN controlled
engine, an electric drive pedal and a larger pump displacement.
The ECO mode function reduces the engine rpm setpoint automatically when a vehicle speed is reached.
This function reduces fuel consumption and noise emission. The pump displacement will increase to
keep the vehicle speed on the same level with a reduced engine rpm. The ECO mode is automatically
switched off if the vehicle slows down or the driver releases the electric drive pedal.
The ECO mode is available in all Automotive Transport modes and can be enabled individually in each of
the four system modes.
Non-automotive work mode
Proportional pump and hydromotor displacement control.
The setpoint of the drive curves are given by the drive pedal command independent of the engine rpm.
The engine rpm is commanded by a handle throttle to fulfill the requirements of the work hydraulic.

Basic functions
System mode selection
The mode switch defines which of the 4 system modes should be applied.
The mode switch has three digital inputs supplied with battery voltage or received via CAN message. For
diagnostic purpose one mode switch is redundant.
The mode change conditions can be defined by parameter.
Mode transition control
This function allows configuration of an application specific System Mode transition.
The System Mode change condition can be dependent on multiple factors including actual FNR
Direction, Drive Pedal Input, and Vehicle Speed.
Drive pedal
The drive pedal is used as the vehicle speed request.
Depending on the propel mode it can be the engine setpoint (automotive mode) or the pump and
hydromotor command (work mode).
The drive pedal has two redundant analogue signals, supplied with 5V sensor voltage or can received via
CAN (EEC2) standard message.
Engine speed potentiometer/hand throttle
The engine speed potentiometer is used as the engine setpoint in work mode.
The engine speed potentiometer has two redundant analogue signals, supplied with 5V sensor voltage
or can received via CAN (EEC2) standard message.
Inching
The inch function allows the operator to reduce the vehicle speed, stop the machine or keep the vehicle
speed low while rising the engine rpm to meet the flow demand of the work functions.
An increasing inch pedal signal will reduce the pump displacement, thus reducing vehicle speed.

Technical Information
Integrated Automotive Controls for H1 and MP1 Single Pumps
Functions
There can be a combination brake/inch of the service brake with an additional sensor for an inch signal or
a separate inch pedal.
The inch pedal has two redundant analogue signals, supplied with 5V sensor voltage or can received via
CAN (EBC1) standard message.
Pump/engine rpm
The pre-installed pump rpm sensor is connected to calculate the pump/engine rpm.
The calculated engine rpm is the setpoint for the automotive drive curve. Optional the engine rpm signal
can received via CAN EEC1 message from the engine controller. In this case, a pump rpm sensor is not
required.
Hydromotor rpm
The hydromotor rpm is measured via a PPU (pulse pickup unit) in the hydromotor. With help of the gear
factor and wheel diameter a vehicle speed is calculated.
The hydromotor rpm is detected by a frequency input with signal level detection. It is supplied with the
5V sensor voltage.
The actual vehicle speed is send out via CAN CCVS message.
Temperature sensors
The temperature sensor integrated in the controller will measure the hydraulic oil temperature.
These functions are:
•
Protection of the complete hydrostatic system by reducing the pump flow (by pump command) at
extreme high temperatures according to user defined temperature curve.
•
Protection of the complete hydrostatic system by reducing the commanded engine rpm at low
temperatures according to a user defined temperature value. When the system has warmed up, the
engine speed limitation is no longer active.
The actual temperature is sent out via CAN TRF1 message.
Pump profiling and ramping
The pump solenoids are supplied by two PWM (pulse width modulation) output signals, independently
configured for the forward and reverse driving direction in each of the four system modes.
For each of the four system modes two independent profile curves for forward & reverse are available.
Hydromotor profiling and ramping
Proportional and 2-Position hydromotors can be controlled directly by a PWM output signal.
The hydromotor command can be defined by a constant value or a profile curve output, individually for
each of the four system modes and driving direction.
Hydromotor brake pressure defeat (BPD) control
The hydromotor BPD control is used in combination with a pressure controlled (PCOR) hydromotor
control.
This function prevents the activation of the internal hydromotor control pressure compensator (PCOR)
during deceleration events. The hydromotor BPD control is activated automatically.

Technical Information
Integrated Automotive Controls for H1 and MP1 Single Pumps
Functions
Maximum hydromotor torque at low vehicle speed
This function will command the hydromotor to max displacement during low vehicle speed to provide
the maximum available torque.
If the defined vehicle speed is reached, the hydromotor will follow the original drive curve. A hydromotor
or vehicle speed sensor is required to detect the actual vehicle speed.
State and direction change
A driving direction change is always handled in a safe way.
The change request by the FNR switch will initiate the deceleration of the vehicle. The change of the
driving direction is only started, if the actual vehicle speed is below a threshold value.
Status LED
In case of an Error, the red status LED on the controller shows a blink code.
The green LED is continuously on if the controller is supplied with battery power.
Protection and safety functions
Start protection
The safety controlled vehicle start protection prevents commanded, unexpected or otherwise dangerous
vehicle movement after initial power on the engine.
The start protection is monitoring the following signals:
•
Engine rpm
•
Battery voltage
•
Error status
•
Inch calibration
•
FNR in neutral
Quick stop in automotive mode
When operating the vehicle in automotive transport mode, the controller will use the engine rpm as the
setpoint. The electric drive pedal position (out of the deadband) is used as an enable signal.
The driver must press the drive pedal and the engine rpm must rise to move the vehicle. If the driver
releases the drive pedal fully (drive pedal return into the deadband), the pump current will decrease with
an adjustable ramp to a defined value. The vehicle will decelerate much faster compared to the normal
behavior.
Operator presence detection
Driving the vehicle is only allowed if the operator is seated on the driver seat. A programmable time delay
will trigger vehicle shut down if the driver leaves the seat for a longer period of time.
Before a pre-warning signal is shown, there is a possibility to override the seat switch if the driver is
pressing the drive pedal.
Hydromotor overspeed protection
The hydromotor overspeed protection prevents the hydromotor from over speeding by decreasing
pump displacement or increasing hydromotor displacement.
The hydromotor rpm speed limit, is user defined and valid in all four system modes when activated.

Technical Information
Integrated Automotive Controls for H1 and MP1 Single Pumps
Functions
Hydraulic system overheat protection
The temperature sensor in controller will measure the hydraulic oil temperature.
The function protects the complete hydrostatic system by reducing the pump flow (by pump command)
at extreme high temperatures according to user defined temperature curve.
Performance functions
ECO fuel saving mode
The ECO fuel saving mode is designed for the automotive transport mode. It needs a CAN controlled
engine (TSC1 & EEC2), an electric drive pedal and a larger pump displacement.
The ECO mode function reduces the engine rpm setpoint (TSC1) automatically when the defined vehicle
speed is reached. This will reduce the fuel consumption and noise emission. The pump displacement will
be increased to keep the vehicle speed on the same level with a reduced engine rpm. The ECO mode is
automatically switched off if the vehicle slows down or the driver releases the electric drive pedal.
The ECO mode is available in all automotive transport modes and can enabled individually in each of the
four system modes.
Cruise control
The cruise control will keep the vehicle speed constant during driving.
The driver can release the drive pedal if cruise control is enabled. The software will keep the vehicle
speed constant by adjusting the setpoint.
An actuation of the drive pedal above the captured value (higher wins) will accelerate the vehicle.
If the drive pedal is released again, the vehicle speed will return to the captured value.
If cruise control is enabled, the driver can increase or decrease the vehicle speed by pressing a button.
The speed steps and trigger time can be set by parameter.
Cruise control is working only in forward driving direction, all cruise states are send out via proprietary
CAN message.
Vehicle constant speed drive (CSD)
The CSD function will allow driving with a constant vehicle speed, independent of the engine rpm.
If the actual vehicle speed differs from the commanded speed, the CSD function will adjust the pump and
hydromotor command to compensate the speed difference. The speed setpoint usually comes from an
electric drive pedal. For the feedback a hydromotor or vehicle speed sensor is required.
Vehicle speed limitation
The vehicle speed limitation prevents the machine from over-speeding.
It can configured separately for each system mode and driving direction. The vehicle speed is calculated
from the hydromotor rpm, the gear factor and the wheel diameter.
Filter for drive pedal
When driving over a field or other rough terrain, the vehicle is shaking and the driver has no chance to
keep the electric drive pedal constant in one position, the filter function for the drive pedal is able to
mitigate this short movement.
The filter can configure individually in each system mode.

Technical Information
Integrated Automotive Controls for H1 and MP1 Single Pumps
Functions
Dynamic brake light
The digital brake light output is switched on if the inch/brake pedal command exceeds a user defined
value or the calculated deceleration is too high (measured by the hydromotor rpm sensor).
This function applies the brake light if the vehicle decelerates by the hydrostatic system. There will be an
on/off delay to avoid flickering of the brake lights.
Automated park brake control
The park brake can applied automatically by CAN message RCI (PGN FF30 - Signal Brake Remote Request)
or the following:
Software machine state in STOP mode
•
Actual pump valve current below user defined value
•
Actual inch pedal command exceeds user defined value
•
Actual vehicle speed is lower than a user defined value
•
Delay times for park brake applied and released are individually configurable.
The park brake logic support the “negative brakes” and is connected in closed loop, that means + and –
are connected to the controller.
Brake applied = output is switched off
Brake released = output is switched on
Reverse buzzer
The reverse buzzer is switched on if the FNR is set to reverse.
Vehicle speed dependent output
The vehicle speed dependent output signal toggles a digital output when the actual vehicle speed
exceeds a user defined value. It can be used as a e.g. speed dependent load stabilizer.
Load independent pump displacement control (option AC2)
The load independent pump displacement control maintains commanded swash plate position
independent of load (Non-Automotive, similar to EDC behavior) using electronic feedback from the
pump swash plate angle sensor.
The function can be enabled individually for each of the four system modes. Two independent profile
curves for forward & reverse are available.
J1939 CAN subsystem data interface
The AC control can exchange information with the vehicle system via the CAN bus.
The following standard messages are supported:
•
TSC1 (torque/speed control)
•
EEC1 (pump/engine rpm)
•
EEC2 (drive pedal)
•
EBC1 (inch pedal)
•
ETC5 (FNR)
•
VH (vehicle hours)
•
RCI (brake remote control)
•
OPS (operator presence)
•
CC VS (vehicle speed)
•
VEP1 (battery voltage)
•

Engine control and protection
J1939 CAN engine interface
The AC controller can exchange information with the engine via the CAN J1939 protocol (TSC1 message)
CAN messages can be individually activated and designated for usage.
The following functions and standard messages are provided:
•
Engine speed control
•
Engine anti-stall protection
•
All range engine overspeed protection
•
Engine overspeed protection with retarder function
•
Cold start protection
Kubota engine protocol
The AC controller supports the properitary Kubota Engine protocol. It is available on request. Please
contact your local Danfoss representative.
Engine anti-stall protection
The engine anti-stall protection prevents the engine from being stalled due to overload.
The commanded engine rpm (TSC1) is compared with the measured engine rpm. If the engine is
drooped, the engine anti-stall function will reduce the hydrostatic propel command to reduce the engine
load and the vehicle speed.
The engine anti-stall function can be individually enabled for each system mode and is configurable. It
works only with CAN controlled engines.
All range engine overspeed
The engine rpm is monitored in all driving situations, but only if the vehicle is moving. Therefore a speed
sensor in the hydraulic motor is mandatory.
When the system detects an engine overspeed situation, the pump will swivel out. That will limit the
deceleration of the vehicle. The driver must use the service brake to reduce the vehicle speed.
The engine rpm range for the overspeed detection can be defined by parameter. Time ramps for
activation and de-activation of the function are available.
Engine over speed protection with retarder
The engine rpm dependent retarder control toggles a digital output when the actual engine rpm exceeds
a user defined level. The retarder can activate a valve of the work hydraulic to give load to engine and
prevent an over speeding.
Cold start protection
An integrated temperature sensor will measure the system temperature.
If the temperature is lower than a user defined level, the engine rpm command (TSC1) is limited until the
system is warmed up to protect the engine and the hydraulic system.

General requirements and recommended settings of a pedal or potentiometer
The pedal must be supplied with AC sensor supply voltage and must not exceed the maximum
•
output current (overload).
This pedal must produce two electrically independent output signals that are in direct correlation
•
with each other. The difference of the two input signals should be 500 mV. The redundant tolerance
should be set to +/- 200 mV.
The first output signal is used as the source of pedal position signal. It must rise when the pedal is
•
pressed. The second output signal is used for diagnostic purposes.
The voltage range of the output signals should not be lower than 5% and not higher than 95% of
•
sensor voltage. Upper and lower voltage limits to pedal supply are requested for wire-fault detection.
Engine speed potentiometer/hand throttle
The engine speed potentiometer is used as the engine setpoint in work mode.
The engine speed potentiometer has two redundant analogue signals, supplied with 5V sensor voltage.

The inch function allows the operator to reduce the vehicle speed, stop the machine or keep the vehicle
speed low while raising the engine rpm to meet the flow demand of the work functions.
An increasing inch pedal signal will reduce the pump displacement, thus reducing vehicle speed. There
can be a combination brake/inch of the service brake with an additional sensor for an inch signal or a
separate Inch pedal, supplied with 5V sensor voltage.
