A method in which the driving behavior of a vehicle is influenced depending on surroundings data in order to support an evasive maneuver as soon as a risk of collision is detected using the data from surroundings sensors and vehicle sensors. The vehicle has an electronically regulated braking system which allows a driver-independent build-up and a modulation of the braking forces on the individual wheels of the vehicle, and a steering input by the drive is supported in the event of a detected risk of collision by a driver-independent braking intervention. A brake slip of at least one wheel of the vehicle is limited to a first slip threshold in a first phase of the evasive maneuver and to a second slip threshold in a second phase of the evasive maneuver, wherein the first slip threshold is smaller than the second slip threshold. The invention further relates to an electronic controller.

A method for controlling a hydraulic brake system for a motor vehicle to carry out a braking operation by means of at least one wheel brake includes, in a first step, a pressure buildup in the wheel brake, wherein hydraulic fluid is passed to a wheel brake via a normally open inlet valve. In a second step, a pressure reduction takes place in the wheel brake, wherein hydraulic fluid is discharged from the wheel brake via an energized normally closed outlet valve. The pressure reduction at the wheel brake is accomplished by means of control of the outlet valve in a predefined manner.

An ESC 33 increases distribution of a braking force to rear wheels according to a reduction in a speed of a vehicle due to braking, and distributes the braking force so as to allow the vehicle to be kept stopped due to braking forces applied to the rear wheels when the vehicle stopped. Then, a second ECU holds the braking force by driving a parking mechanism with the vehicle kept stopped due to the braking forces applied to the rear wheels.

An apparatus for controlling a braking force of a vehicle is provided. The apparatus includes a sensor device that obtains information about an image in front of the vehicle and driving information of the vehicle and a controller that determines a road surface state including a left road surface state and a right road surface state based on the information about the image and the driving information and controls a braking force of left wheels of the vehicle and a braking force of right wheels of the vehicle respectively based on the left road surface state and the right road surface state of the vehicle.

Methods and systems are described for controlling a vehicle braking system. A braking force is applied to the vehicle by applying friction only braking to the wheels of one axle and applying a blended braking force (including a regenerative braking force and a friction braking force) to the wheels of another axle. Using vehicle and tire modeling techniques, a set of side-slip angles is calculated that is estimated to occur if the total braking force were applied using only friction braking. A compensatory yaw moment is then determined based on differences between the estimated side-slip angles and the actual side-slip angles of the vehicle under the blended braking. The compensatory yaw moment is then applied to the vehicle to enable the vehicle to utilize regenerative braking while exhibiting the same vehicle dynamics that occur when using friction braking only.

System, methods, and other embodiments described herein relate to emergency lateral maneuvers using brake-induced tire sliding. In one embodiment, a method includes determining a vehicle state for a vehicle according to sensor data about a surrounding environment.

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.
