Abstract: A method for testing a hydraulic braking system. The method includes activating a brake master cylinder of the braking system mechatronically, and measuring a set of measured decision ratios pertaining to the distance travelled by the piston of the brake master cylinder to the corresponding pressure developed in the brake fluid. The measured decision ratios are then compared with a set of reference decision ratios. In a case where the measured decision ratios lie within a predetermined range, it is detected that the braking system is correctly filled with the brake fluid. However, in a case where the measured decision ratios lie outside the predetermined range, it is determined that the braking system has not been correctly filled with the brake fluid and some air is present in the brake fluid flow circuit of the braking system.

Abstract: A method of operating a brake assistance system in a vehicle is disclosed. The method includes determining a braking operation as an emergency braking situation, which in turn includes sensing a braking pressure applied to a brake pedal, determining a braking pressure gradient of the braking pressure, and evaluating at least one factor of the driving situation, checking whether that factor indicates an emergency braking situation. If that factor indicates an emergency braking situation, adjustments to a braking pressure threshold value and a braking pressure gradient threshold value are carried out, reducing those threshold values by a predetermined amount. Thereafter, if both the braking pressure and the braking pressure gradient exceed the adjusted braking pressure threshold value and the adjusted braking pressure gradient threshold value, respectively, the braking operation is identified to be an emergency braking situation, accompanying activation of an emergency braking cycle.

Abstract: A method for operating a service brake system in a vehicle is described. The method includes the stages of determining whether the vehicle is stationary, and detecting whether the brake pressure exceeds a predetermined value in that stationary state. If the brake pressure value exceeds the predetermined value, as part of final stage, the method includes regulating the brake pressure to a predefined limiting value, where the predefined limiting value is sufficient to maintain the vehicle in that stationary state.

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.
