  • Patent number: 11247678
    Abstract: A method for operating a motor vehicle having partial/full autonomous driving, having a plurality of wheels, a drive system for producing a drive torque at at least one of the wheels, and a brake system for producing at least one holding force for holding still at least one of the wheels, a rotational speed sensor being allocated to at least one of the wheels, which sensor produces a respective signal pulse for each of a plurality of positions of angular rotation of the associated wheel, a specifiable driving maneuver being performed as a function of the produced signal pulses. For a short path driving process starting from a standstill, the brake force is reduced until the rotational speed sensor produces a first signal pulse, and is then held at least temporarily constant until a specified number of signal pulses is produced, and subsequently is increased up to the holding force.

  • Patent number: 11242047
    Abstract: A method for operating a motor vehicle, the motor vehicle being automatically accelerated and decelerated as a function of an instantaneous position and a predefinable target location, so that it comes to a standstill at the target location, including the following steps: a) accelerating the motor vehicle, in particular from a standstill, to a predefined setpoint velocity; b) up to a predefined first distance of the motor vehicle to the target location, decelerating the motor vehicle to a predefined rolling velocity; c) starting at a predefined second distance of the motor vehicle to the target location, decelerating the motor vehicle to a standstill, the second distance to the target location being smaller than the first distance.

  • Patent number: 8489301
    Abstract: A device for controlling the brake pressure in a hydraulic brake system with the aid of a pressure-limiting valve that limits the brake pressure to a predefined threshold value, and to that end is driven by an electronic device in accordance with a valve characteristic curve. The setting accuracy can be improved considerably if an estimating unit for estimating the brake pressure, a sensor system for measuring the brake pressure, a unit for determining a pressure difference between the measured brake pressure and the estimated brake pressure, as well as a controller unit which drives the pressure-limiting valve as a function of the pressure difference are provided.
