DPS6 Redundant Digital Power Steering
Redundant Digital Power Steering overrides the conventional steering system of off-highway vehicles. This:
- improves maneuverability
- enables use of GPS and autonomous driving systems without any additional external steering system
The six-phase motor (two independent three-phase units), driven simultaneously by two ECUs, ensures redundancy: if one channel fails, it is possible to steer the vehicle for a few minutes even without the driver on board using the remaining channel (ECU + 3 phases).
The driver has the option to override the system and maintain full steering control through the steering wheel in any situation.
DPS6 is suitable for autonomous driving with dual three-phase actuation and control system.
Vehicles factory-equipped with a DPS6 system are type-approved for on-road use. Each of the two channels of the DPS6 (ECU + 3 phases + resolver) is designed to achieve performance level AgPLd or PLd (ISO 25119 – ISO 13849).
DPS6 has 5 main benefits:
- Synthetic boost curve
- Speed-dependent steering assistance
- Direct integration with GPS
- Active steering wheel return in forward and reverse (meeting ISO 10998 for speed >40kph)
- Autonomous driving-ready in a compact space
Personal settings:
- Free programmable steering rules (Synthetic Boost Curve)
- Non-Reactive/Reactive parametric functions
- Active haptic feedback on steering wheel (machine-to-driver communication vibration)
- Comfort and agility at low speed; very low torque, high return speed
- Stability and accuracy at high speed; optimal steering wheel centering torque
- Active wheels and steering wheel return in forward and reverse
- Easy joystick or miniwheel integration
- Easy auto-guidance integration (GPS)
- Easy interface with vehicle
