Vehicle electrical steering system has control unit that compares sensor signals, drives control devices, mechanical locking device that can fix steering control if steering system voltage supply off

摘要

The system has a steering control (2) operated by the driver and that interacts with at least one steered wheel via an electronic control unit (5), a first sensor (4) for detecting movement or operation of the steering control and a second sensor (7) for detecting wheel position. The control unit compares the sensor signals and drives final control devices (9,11). A mechanical locking device (14) can fix the steering control when the supply voltage for the electrical steering system is turned off.
