Device for controlling a position sensor of the steering wheel of an automobile

摘要

The invention relates to a device (2) for controlling a position sensor (13) of a steering wheel (3) of a vehicle. Said device (2) includes a means (9) for generating a control signal for the acquisition periods of the position sensor (13) when the vehicle is stopped, the frequency of said signal increasing upon the detection of a variation in the position of said steering wheel (3). The invention can be used in the field of automobiles, and the position sensor can be associated with the rotor of the steering assist motor.

主权项

1. A control device for controlling a position sensor configured to detect a position of a steering wheel of a motor vehicle, the control device configured to generate a control signal for acquisition periods of the position sensor when the motor vehicle is stationary,
wherein a frequency of the control signal increases when a change in the position of the steering wheel is detected, wherein the control device generates the control signal for acquisition periods of the position sensor having a standby frequency suitable for detecting a half-turn of a rotor, and wherein the control device generates the control signal for acquisition periods of the position sensor having a frequency, called an active frequency, changing proportionally with a change of the rotation speed of the steering wheel.
