摘要： The invention relates to a method for predicting maintenance/replacement period for a component of a vehicle, the vehicle comprising a power-assisted steering system including a steering actuator (14) configured to assist in steering the vehicle at least as compensation for angular deviations of the road wheels (16) caused by road disturbances. The method comprises acquiring over time steering output data indicative of a magnitude and/or frequency of assisted steering as compensation for angular deviations of the road wheels (16) caused by road disturbances, comparing the acquired steering output data with stored component wear data, the stored component wear data being indicative of when maintenance/replacement of the component is due based on wear caused by road disturbances, and determining, based on the comparison of the acquired steering output data and the stored component wear data, whether or not maintenance/replacement of the component is due. The invention also relates to a system (10).

摘要： The invention relates to a computer-implemented method for automatically deactivating the right or left turn signals of a vehicle at the end of a turn, the method comprising steps consisting in: (a) determining, as long as the right or left turn signals are on, the steering wheel angle with respect to a neutral position in which the two steered wheels of the vehicle are straight, (b) determining (108) the average angle of the steered wheels in relation to their upright position from the steering wheel angle, (d) when the left turn signals are on, automatically deactivating (120) the left turn signals when the average wheels angle exceeds, in relative value, a first positive threshold and then, still in relative value, falls below a second positive threshold, (e) failing this, keeping (118) the left turn signals on, (f) when the right turn signals are on, automatically deactivating (120) the right turn signals when the average wheels angle (A2) falls below, in relative value, a first negative threshold (−01) and then, still in relative value, exceeds a second negative threshold, (g) failing this, keeping (118) the right turn signals on.
