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.

Method for securing the control of the rear wheels of a motor vehicle provided with an electric power steering system

A method for detecting whether a vehicle on standby is in a transported situation, the vehicle including a course control device, wheel speed sensors, a yaw rate sensor, a processing unit processing data managing vehicle operation modes and a device for immobilizing the vehicle. The method includes detecting a vehicle standby mode after installing the vehicle on a transport support, detecting a zero vehicle speed using the wheel speed sensors, the speed sensor of at least one wheel able to be on the verge of oscillating over a predefined time period, detecting a non-zero yaw rate using the yaw rate sensor over a predefined time period, and under these conditions determining the vehicle is in a transported mode, in which data from at least the wheel speed sensor on the verge of oscillating is filtered, and allowing the vehicle to be put in a wake-up state.

Method and device for the detection of a transported situation of a vehicle in standby mode, and vehicle equipped with such a device

A method for monitoring that a vehicle on standby has been correctly immobilized for transport, the vehicle including a course control device, wheel speed sensors, a yaw speed sensor, a processing unit processing information managing operation modes of the vehicle, and a device for immobilizing the vehicle. The method includes detecting the vehicle is in a standby mode at a standstill following installing of the vehicle on a transport support, detecting a non-zero vehicle speed through the speed sensors of at least two wheels over a defined period, detecting a non-zero yaw speed through the yaw speed sensor, over a predefined period, and under these conditions determining a mode whereby immobilization of the vehicle for transport is monitored, in which mode information from at least the wheel speed sensors is filtered after a determined number of attempts at immobilizing the vehicle and allowing the vehicle to be fired up.
