One-error-proof path or angular sensor unit for electrohydraulic steering system for road vehicle, has processing units including control unit for target size determination for controlling actuator and/or for triggering fail-safe-reaction

摘要

The sensor unit (200) has sensors for path and angle detection, processing units, and power outputs (40) controlling an electrohydraulic actuator (500). The processing units include a control unit for target size determination based on determined sensor measurement values for controlling the actuator and/or for triggering a fail-safe-reaction. The processing units are connected with each other for mutual data exchange over an internal connection. A sensing unit generates an output signal for controlling the power outputs, which is proportional to angular speed in velocity and direction. An independent claim is also included for a steering system comprising am axle unit.
