Control Unit and a Method for Adapting a Steer-By-Wire System for an Automobile Driver

摘要

A method (20) and a control unit (10) for adapting a steer-by-wire system for a driver in an automobile is disclosed. Firstly, signals are acquired from a set of sensors comprising at least one of a vehicle speed sensor, a vehicle acceleration sensor, a steering angle sensor, a steering torque sensor and a yaw rate sensor. The signals from the sensors are processed to determine whether the driver is a trained driver or an untrained driver. Secondly, signals are acquired from the set of sensors comprising at least a vehicle acceleration sensor, a steering angle sensor, a steering torque sensor. The signals are then processed using fuzzy logic to determine whether the driver is a low sensitivity driver or a high sensitivity driver. The technical advantage of the above processing is that a steering ratio is applied to the steer-by-wire system to reduce driver fatigue and improve ease of driving.
