1General
The increase in electronic systems in the new Actros means that more and more signals now have to be made available across all the systems. This primarily has an impact on the networking, which has also gained in complexity. Alongside the familiar CAN and ASIC data bus systems the LIN data bus is now increasingly being used. The new Actros alone has 11 LIN data buses, which connect the various control units, switches or other electronic components to each other. The number of CAN data buses by contrast has only risen slightly.
2CAN data bus system
The CAN data bus system enables information to be exchanged quickly and reliably between control units over only a few lines. The information is sent or received successively (serial). The exchange is bidirectional, i.e. each control unit operates as both a transmitter and a receiver.
2.1 Transfer rates
In the new Actros up to 13 different CAN data buses are used. The majority of these CAN data buses have a transfer rate of >250 kBaud and this classes them as high>speed CAN data buses. The reasons for the increase in high>speed CAN data buses are:
•Increase in data rate (number of messages that are sent)
•Almost identical manufacturing costs as for low>speed CAN data buses
•Greater use of LIN data bus in non>critical safety areas
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
•Shortening of flash or parameterization times, in particular through increase in transfer rate for diagnostic CAN (CAN 10)
The following CAN data buses have a transfer rate of 500 kBaud:
•Exterior CAN (CAN 1)
•Interior CAN (CAN 2)
•Frame CAN (CAN 3)
•Climate control CAN (CAN 5)
•Front axle brake CAN (CAN 6a)
•Rear axle brake CAN (CAN 6b)
•Redundancy brake CAN (CAN 6c)
•Brake CAN ESP“ (CAN 6d)
•Diagnostic CAN (CAN 10)
•Radar CAN (CAN 12)

Functions
The transfer rate of the drive train CAN (CAN 4) was increased to 667 kBaud, because the high number of messages had significantly increased the bus operating rate. If the data rate was not increased, then there is the risk that some messages with low priority could no longer be sent due to the bus operating rate.
To ensure that freight forwarders, for example for fleet management, can continue to call up specific information on vehicle location, current speed, etc. the transfer rate of the telematics CAN (CAN 9) has been retained at 250 kBaud.
The transfer rates have also been retained on the trailer CAN (PSM) (CAN 7), the body manufacturer CAN (PSM) (CAN 8) and the trailer CAN (EBS) (CAN 11). They are 125 kBaud, whereby they are still classified as low>speed CAN data buses.
The transfer rate for the NOx>CAN (CAN 13) has not been changed either and is > as before > 250 kBaud.
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
2.3CAN neutral points and bus terminating resistors
Because of the high transfer rates on high>speed CAN data buses, there may be some reflections in the lines. Bus termination resistors are used to avoid reflections that would lead to the falsification of actual information. The characteristic impedance of the electrical line is important for the bus termination resistor. The total bus terminating resistor on a high>speed CAN data bus is 60 ].
In the neutral points for the cab instrument panel CAN bus (Z1) and frame CAN bus (Z3) the bus terminating resistors are integrated into the neutral points. The drive CAN bus neutral point (Z4) only includes those ferrite elements that are also installed in the neutral points for interference suppression of
high>frequency interference pulses.
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
3LIN data bus
The LIN data bus is an inexpensive serial subbus, which replaces the CAN data bus in the area of uncritical data transfer. The voltage supply for the LIN data bus is 12 V. This is realized internally in the control units through voltage dividers. Signals are transmitted through a single>wire line. The max. data rate is 20 kBaud. Communication refers to ID>based communication. All subscribers connected to the LIN data bus receive the message, but only one subscriber responds to it.
A LIN data bus subscriber never sends information by itself, as is the case, for example with a CAN data bus subscriber. Subscribers of the LIN data bus only ever respond to a query.
2.2Gateways
To compensate for the different transfer speeds, some control units also act as a gateway:
•The central gateway control unit (CGW) (A2) routes the respective messages from the exterior, interior, frame, telematics and diagnostic CAN (CAN 1, 2, 3, 9 and 10).
•The modular switch panel (MSF) control unit (A43) acts as a gateway between the interior CAN (CAN 2), the ASIC data bus (ASIC) and the three LIN data buses to the button groups on the multifunction steering wheel, the left multifunction control lever and the level control operating unit.
•The Electronic Brake Control (EBS) control unit (A10b) or (A10c), depending on the version, sends the messages from the frame CAN (CAN 3) to the front axle brake CAN (CAN 6a), the rear axle brake CAN (CAN 6b), the brake CAN ESP“ (CAN 6d) as well as, where applicable, the trailer CAN (EBS) (CAN 11) and vice versa.
•The drive control (CPC) control unit (A3) acts as an interface between the frame CAN (CAN 3) and the drive train CAN
(CAN 4).
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
The bus terminator on the exterior CAN (CAN 1) is realized by using bus terminating resistors within the central gateway control unit (CGW) (A2) and the Electronic Air>Processing Unit (EAPU) control unit (A18). Located in both control units is a 120 ] resistor each. The parallel connection then yields a total bus terminating resistance of 60 ].
In the diagnostic CAN (CAN 10) the bus terminator is realized by a 60 ] resistor in the central gateway control unit (CGW) (A2).

Functions
4ASIC data bus system
The previously familiar ASIC data bus system is also used in the new Actros.
The ASIC data bus (ASIC) belongs to the so>called subbuses. In contrast to conventional switches which switch via their own contacts and are connected to their components via separate electrical lines (e.g. motors, solenoid valves, switch inputs, lighting devices), the ASIC data bus performs these tasks.
The electronics installed in the ASIC signal switches notifies the modular switch panel (MSF) control unit (A43) the following via the ASIC data bus (ASIC):
fswitch position (open, closed, operated, not operated)
fFunctionality (normally closed contact, normally open contact, changeover contact)
fSystem affiliation (e.g. headlamp cleaning system button,
power take>off 1 button, etc.)
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
5Virtual control units
Each ASIC signal switch is connected over three contacts (pins) to the ASIC data bus (ASIC), and it is evaluated by the modular switch panel (MSF) control unit (A43). It is thus possible to install each ASIC signal switch at any arbitrary point on the individual switch modules.
For currents up to a maximum of 20 A there continues to be load switches which as before switch via their own contacts and are connected to their components through electrical lines.
These load switches are only connected to the switch panel via the ASIC contacts for separate background lighting.
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
6Safety strategy
Virtual control units are not equipped with their own housing. They are integrated into the hardware and software of other control units. In Star Diagnosis and the instrument cluster control unit (ICUC) (A1) they appear as independent control units. Among the virtual control units are the central data memory (CDS) (A2 a1), the communications interface (COM) control unit (A2 a2) and the maintenance system (MS) control unit (A2 a3), which are all integrated into the central gateway control unit (CGW) (A2).
With the aid of the central data memory (CDS) (A2 a1) the parameters for the electronic control units can be reset to manufacturer default settings.
Several control units have a redundant connection over LIN or CAN data buses. The redundant connection serves as an emergency communication, if the actual CAN connection malfunctions. The use of redundant LIN or CAN data buses is dependent on the safety relevance of each system.
The service brake system, for example has a redundant CAN data bus connection between the axle modulators.
LIN data buses serve as redundancies between the sensor and actuator module, cab (SCA) control unit (A7) and the sensor and actuator module, chassis (SCH) control unit (A8) as well as between the instrument cluster control unit (ICUC) (A1) and the Electronic Air>Processing Unit (EAPU) control unit (A18).

General information
The maintenance system (WS):
fIs a software which is integrated as a virtual control unit into the central gateway control unit (CGW) (A2),
frecords all the required measurement data as CAN messages
(1) using the CAN data bus system and
fcalculates the load>dependent service life and forecast data for each maintenance item in order to determine the service dates.
i Load>dependent forecasting is used to carry out the following:
fIndividual determination of the service dates for each maintenance item and they can be called up in the "Maintenance" (2) menu of the instrument cluster control unit (ICUC) (A1).
fDisplay of pending maintenance items as a message in the multifunction display (A1 p1) when the ignition is switched on.
The menu is operated using the left multifunction steering wheel button group (S110) and the right multifunction steering wheel button group (S111).
Maintenance information is shown in the multifunction display (A1 p1) of the instrument cluster control unit (ICUC) (A1). The instrument cluster control unit (ICUC) (A1) acts as a display unit.
A maintenance item is reset using the left multifunction steering wheel button group (S110) and the right multifunction steering wheel button group (S111) or with the aid of Star Diagnosis through the diagnostic socket (X100.16).

Functions
General information
The recording of data function enables the maintenance system (WS) to receive two different types of input factors for calculating the load>specific maintenance intervals:
fBasic data, which are determined unchangeable at first in the form of a parameterization and
fmeasured values, which are sensed continuously.
Thus, two functions are differentiated:
fAcquiring the basic data
fAcquiring the measured values
Acquiring the basic data
The maintenance system (WS) requires certain basic data (parameters), which:
fare a prerequisite for the general function and
fwhich are used to adapt the maintenance system (WS) to the vehicle and the operating fluids.
The basic data are acquired in the form of the following parameterizations:
fBasic parameterization
fVehicle>specific parameterization
fSubsequent parameterization
fParameterization of operating fluids
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
Subsequent parameterization
Subsequent parameterization:
fmakes it possible to change parameters, which are connected to constructional vehicle changes for instance or special customer's requests, such as the "time>based servicing scheme grid" parameter and
fmay only be carried out in workshops authorized by Mercedes>Benz.
i Querying and operation are conducted using the left multifunction steering wheel button group (S110) and right multifunction steering wheel button group (S111) or using Star Diagnosis through the diagnostic socket (X100.16).
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
Basic parameterization
The basic parameterization (base parameterization):
fincludes the pre>assignment of certain parameters with values and is a prerequisite for the function of the maintenance system (WS) and
fis made at the manufacturer of the central gateway control unit (CGW) (A2).
Vehicle>specific parameterization
The vehicle>specific parameterization:
fis used to adapt the maintenance system (WS) to the vehicle model and the vehicle equipment, or to the special features of the individual maintenance items, such as
their cut>in or cutout and
fis carried out in the Mercedes>Benz production plant.
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
Parameterization of operating fluids
Parameterization of operating fluids:
fmakes it possible to change parameters with regard to the properties of fuels and lubricants, which can change during the operation of the vehicle, such as engine oil quality, engine oil viscosity, transmission oil quality, or sulfur content of the fuel and
fmay also be carried out by other workshops.
i The parameters can be checked and changed if necessary through the "Fuels and Lubricants" submenu in the "Adjustments" menu of the menu system. Querying and operation are conducted using the left multifunction steering wheel button group (S110) and right multifunction steering wheel button group (S111) or using Star Diagnosis through the
diagnostic socket (X100.16).
