SYSTEM DESCRIPTION (FEATURES)
The Dynamic Power Steering (DPS) provides a computer controlled, variable power assist, achieved by an electric motor to optimize the amount of steering input required by the rider.
vmr2010-003-014_a
1. Dynamic power stee
The DPS system uses the following parameters to determine how much steering assist it provides:
–EngineRPM – Battery/electric – Vehicle speed – DPS shaft torque sensor input.
The amount of steering assist provided is depen­dent on the handlebar effort (steering torque), electrical power available, and vehicle speed.
ring unit (DPS)
al system voltage
The greater the handlebar effort (torque), the greater the assist will be.
The slower the vehicle speed, the greater the as­sist will be.
If the electrical system is activated but the engine is not running, there is no power assist provided.
When the handlebar is in the straight ahead posi­tion, there is no steering assist.
Steering torque may also come from the wheels due to rough terrain. Steering kickback is reduced while providing feedback to the driver.
The greater the power steering assist, the greater the load on the electrical system.
When the electrical system i s under high load (battery not at full charge, operating the vehicle for prolonged periods of time at slow speed and low RPM which, requires higher power steering assist), the battery power reserve will gradually decrease. This further increases the load on the charging system and the electrical system volt­age will drop. As system voltage drops, so does power steering assist.
NOTE: It is important to maintain the battery at a full state of charge to ensure proper DPS oper­ation. The magneto output is 650 watts to mini­mize battery drain and system voltage drop.
DPS Assist Mode
The DPS system provides three rider selectable modes of operation.
DPS MAX provides maximum steering assist for technical low speed riding in rough or muddy ter­rain, or for touring.
vmr2015-142 511

Section 07 CHASSIS
Subsection 03 (DYNAMIC POWER STEERING (DPS))
DPS MED provides normal (medium) steering as­sist for general all purpose riding.
DPS MIN provides less steering assist for in­creased feedback and aggressive trail riding.
A fourth mode of operation is available as an ac­cessory to adjust the steering assist level for op­eration with an approved BRP track kit.
Derating Explanation
Derating is an internal protection system inte­grated in the DPS electronic module.
This system protects the electronic components when DPS works too hard and the internal tem­perature reaches a critical level.
It also protects electronics when current ripples in the system are too high. These current ripples can be caused by:
– Loose battery connections – Low battery voltage – Bad grounds – Defective stator or bad stator output wires con-
nection – Failed regulator – High electrical loads.
The internal protection system decreases the assistance level available to protect its electronic board. The normal assistance level will return when riding conditions are back to normal and the internal temperature decrease and/or when the ripples in the electric circuit decreases.
NOTE: This reaction i s a normal protective behav­ior of the unit and it does not necessarily raise a fault in the cluster.

The DPS module provides DC power to the mo­tor. The amount and duration of that DC power is determined by the inputs to the DPS module. The direction in which the motor turns is changed by reversing the polarity of the circuit current.

To protect the DPS electronic components, the steering assist behavior will change as follows.
When motor internal temperature reaches a certain temperature (DPS continuously estimates it)

When the handlebar is turned, torque is applied to the shaft which tends to twist the shaft slightly, deforming the magnetic field in the shaft. The sensor detects the torque by measuring the devi­ation of the magnetic field.
The torque sensor is very sensitive and can de­tect very small changes in the magnetic field. The harder the handlebar is turned, the greater the magnetic deviation, the greater the power steering assist.
