  • Patent number: 12330617
    Abstract: In the case of a method for operating a brake system of an at least double-tracked motor vehicle (10) which comprises 2 breakable wheels (12L, 12R), which are arranged at opposite ends of an axle (14V), and a rollover protection system, which can cause braking of the wheels (12L, 12R) in order to prevent a rollover situation, automatic braking of that wheel of the axle (14V), which is loaded more greatly when cornering is brought about by way of the rollover protection system. Subsequently, a counter-steering movement is detected by way of a predefined steering angle change being exceeded in a predefined time period in the direction counter to the cornering direction, and, thereupon, a brake force is caused to be built up at the opposite wheel, which is loaded less greatly by way of the rollover protection system.

    Abstract: A method for operating a brake system of an at least double-tracked motor vehicle comprises two breakable wheels, which are arranged at opposite ends of an axle, and a rollover protection system which can cause braking of the wheels in order to prevent a rollover situation. Automatic braking of that wheel of the axle which is loaded more greatly when cornering is brought about by way of the rollover protection system. Subsequently, a smaller steering lock angle or a lower lateral acceleration than in the case of the cornering which took place immediately previously, or a straightahead driving phase which immediately follows the cornering is detected. Thereupon, automatic braking of the two wheels on the axle is brought about.

  • Publication number: 20230111431
    Abstract: A method for detecting a resistance on a brake pedal of a brake system, in which a brake pedal is pulled by an actuator, in which an ease of movement of the brake pedal is determined during operation of the actuator, wherein a resistance is detected as soon as the ease of movement is no longer clearly determined, and a method for controlling an actuator, a computer program product, control unit or system comprising a plurality of control units, and a corresponding device.

  • Patent number: 10569750
    Abstract: A fuzzy-based control system in a motor vehicle for controlling a speed comprises a brake pressure measurement unit, a signal processing unit and a control unit. The brake pressure measurement unit is adapted as a finite state machine to measure a current brake pressure of a brake of a wheel of the motor vehicle dependent on a trigger. The signal processing unit is adapted to estimate a current adhesion value ? between a tyre associated with the wheel and the current ground, based on the current brake pressure of the brake and further measurement values. The estimating comprises an inference based on fuzzy rules and a fuzzification, a subsequently a defuzzification of the inference. The control unit is adapted to control a speed of the motor vehicle or the brake pressure of the brake, based on the estimated current adhesion value ?.
