Abstract: The invention relates to a motor vehicle device including a one-piece fastening system of the motor vehicle. This fastening system includes a fastening flange, a guiding member having at least one supporting member and a supporting surface participating in maintaining the guiding member in a first position, and an elastically deformable portion exerting a restoring force adapted to restore the guiding member into said first position.

Abstract: An aerodynamic blade for a motor vehicle includes a shutter mounted on a support shaft having an axis and connected to a chassis of a vehicle by at least one support, and driven in rotation around said axis between an open position and a closed position by a motor assembly. The motor assembly includes one or more elements configured to accumulate mechanical energy and having an adjustable stored energy level to meet a demand for a sufficient torque to change a position of the shutter in a time of less than one second.

Abstract: 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.

Abstract: 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.
