Embodiment Construction

[0030] figure 1 A motor vehicle 1 is shown schematically, which is suitable for carrying out the method according to the invention. It has a drive motor 2 driving at least some of the wheels of the vehicle, a steering wheel 3, a brake pedal 4 connected to a tandem master cylinder (THZ) 13, and four individually actuatable wheel brakes 10a-10d. The method according to the invention can also be carried out when only some of the wheels are being driven. In addition to hydraulic friction brakes or instead of hydraulic friction brakes, it is also possible to use electromechanically actuated friction brakes as wheel brakes on one, several or all wheels. According to an alternative embodiment of the invention, the vehicle has an electric drive, and the braking torque at at least one wheel is at least partially generated by the electric machine / electrical machines operating as generators.

[0031] In order to detect the driving dynamics, there are steering wheel angle sensors 12 for...

Abstract

The invention relates to 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 driver is supported in the event of a detected risk of collision by means of a driver-independent braking intervention. According to the invention, 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.

Description

technical field [0001] The invention relates to a method according to the preamble of claim 1 and an electronic controller according to the preamble of claim 10 . Background technique [0002] The Electronically Adjusted Braking System provides functions like Antiskid Control (ABS), which prevents wheel locking during full braking, and Dynamics Adjustment (ESC) through active Targeted braking interventions act on the vehicle in a stable manner during dynamic driving maneuvers; in addition to electronically regulated braking systems, motor vehicles are increasingly also equipped with environmental sensors, which can detect other traffic Participants and inactive obstacles and determining their position or velocity relative to the ego vehicle. [0003] Networking of environmental sensors and electronically regulated braking systems enables distance control (ACC) to preceding vehicles, in particular alerts the driver in the event of an emergency, and automatically initiates em...
