Problems solved by technology

[0005] If the service brake system now fails in an autonomous or partly autonomous function, for example due to a failure of the brake actuator or the brake controller, the motor vehicle is no longer automatically braked, which can lead to collisions with other objects collision

Embodiment Construction

[0071] figure 1 A schematic block diagram of a driver assistance system is shown, which is denoted overall by the reference numeral 101 . The driver assistance system 101 basically comprises a controller 102 for the driver assistance system 101 with a driver assistance system algorithm 103 and a service brake system 112 which includes a pressure generator 105 (for example a hydraulic unit) with Associated controller 104 is also used to regulate the braking force acting on wheel brakes 110 , as well as wheel brakes 110 .

[0072] In addition to the service brake system 112, the driver assistance system 101 also includes a parking brake system 114 (also referred to as automatic parking brake or parking brake), which is controlled by the controller 108, the parking brake regulator 109 and likewise the wheel brake system 114. brake 110.

[0073] Below the wheel brakes 110 are summarized all the components which are involved in generating the holding force, for example downstream...

Abstract

The method according to the invention for operating a motor vehicle, wherein at least one autonomous or partially autonomous operation of the motor vehicle can be activated and the motor vehicle has a service brake and a parking brake, is characterized in that, in response to the detected motor The operating state of the motor vehicle is small, the parking brake is brought from a stationary state to a predetermined operating state, wherein the predetermined operating state of the parking brake is determined in such a way that the parking brake does not produce a braking effect or produces a relative Significantly less braking action at full activation.

Description

technical field [0001] The invention relates to a method for operating a motor vehicle and a device for operating a motor vehicle. Background technique [0002] Functions for (partially) autonomous driving operations are increasingly provided in motor vehicles. These currently include in particular the functions "autonomous parking (parking)" and "adaptive speed regulation". In the case of the "autonomous parking" function, for example, the driver of a motor vehicle is supported when adjusting the vehicle, especially during parking. In this case, the environment of the motor vehicle is detected by means of sensors and the motor vehicle is automatically braked if it comes too close to another object, for example a parked motor vehicle. The function "adaptive speed regulation" also works in a similar way, and it realizes an automatic driving and braking based on the decelerating or stopping of the preceding motor vehicle. Known driver assistance systems generally include a ...
