A method for controlling an actuator for steering a wheel of a motor vehicle including an electrical actuator controlling steering angle of the steering wheel and a mechanism determining temperature of the actuator. The method includes: completing deactivating the actuator; and a counter-steering operation triggered when the temperature of the actuator is higher than or equal to a determined prevention threshold.

Method for controlling a steering actuator comprising a counter-steering step before a deactivation step

A method for securing control of rear wheels of a motor vehicle including an electric power steering system, the method including: measuring or calculating, using a motor-angle sensor, at least angular position of the electric power steering motor, and measuring or calculating, using a steering-wheel angle sensor, at least angular position of the steering wheel; calculating, using the motor-angle sensor, at least the angular position of the steering wheel; comparing at least the angular position of the steering wheel measured using the steering-wheel angle sensor to the angular position of the steering wheel measured using the motor-angle sensor; and transmitting an alarm signal if the result of the comparison is greater than a predetermined threshold value.
