Abstract
A method for avoiding reducing scoring of the brake disc or the brake drum of a vehicle driven under rainy conditions calculates a product of three parameters, and activates an automatic braking operation for the vehicle, regularly, whenever the product exceeds the pre-determined threshold level. The first parameter is a rain intensity based parameter, a measure of the current raining intensity. The second parameter is a brake-activation-free driving time parameter, representing the time elapsed since the braking system of the vehicle was activated last. The third parameter is a speed parameter, which represents a current speed of the vehicle. As the automatic braking operation is carried out, the particles of dust, water, snow and de-icing substances, adhered to the brake disc of the vehicle, and causing scoring of the brake disc, are quickly removed, thus, reducing disc scoring.
