Embodiment Construction

[0027] With the help of the speed parameter, unnecessary automatic braking processes can be effectively avoided, for example in stop-and-go traffic or even when the vehicle is stationary during rain.

[0028] According to a further advantageous development of the invention, the automatic braking procedure is only executed when the vehicle speed has additionally reached at least a predetermined minimum speed. This advantageously prevents automatic braking procedures from being performed at low speeds, where the vehicle deceleration caused by the automatic braking procedures may be more noticeable to occupants of the vehicle than in high speed driving situations. As a result, deceleration of the vehicle, which may be unpleasant for occupants due to the automatic braking procedure, is avoided and driving comfort is thus increased.

[0029] A further advantageous development of the invention provides that only the rain intensity parameter is provided by the vehicle's rain sensor. ...

Abstract

The invention relates to a method for avoiding reducing scoring of the brake disc or the brake drum of a vehicle driven under humid conditions. According to the method, a detection value is determined, and when the detection value arrives at a pre-determined trigger threshold value, an automatic braking program is executed along with speed reduction of the vehicle which basically cannot be noticed by the driver. According to the invention, the detection value is formed by multiplying at least one of parameters of rain intensity based parameter, brake-activation-free driving time parameter and a speed parameter which relies on the vehicle speed.

Description

technical field [0001] The invention relates to a method for performing an automatic braking procedure in wet conditions to avoid the formation of scratches on a brake disc or a brake drum of a vehicle braking device. Background technique [0002] The tendency of the brake linings of a vehicle brake to accumulate small metal particles that can cause scratches to the brake disc or drum of a vehicle brake has always been significantly increased, especially in wet weather conditions. This problem is also exacerbated in winter as the water becomes mixed with snow and de-icing salts. Continuous formation of scratches on brake discs or drums during long-term operation can lead to a non-negligible mechanical weakening of brake discs and drums, especially under high thermomechanical stress. Since the brake linings contact the brake disc or drum of the vehicle's braking device during the automatic braking procedure, moisture and dust particles can be largely removed from the brake d...
