Embodiment Construction

[0029] figure 1 A motor vehicle 1 is shown, which can be, for example, a motor vehicle, in particular a passenger car, a truck or a passenger bus. Motor vehicle 1 may have a hydraulic braking system 2, wherein figure 1 Wheel brakes 3 and hydraulic brake pressure lines 4 are shown. The brake pressure in the brake pressure pipe 4 can be adjusted through the electronic stability program 5, wherein figure 1 Shown is the brake controller ESC. Brake controller ESC can be connected to communication device 6 of motor vehicle 1 . The communication device 6 can be a data bus, for example a CAN bus. Furthermore, the communication device 6 can be connected to the airbag device 7 and the pedal position sensor 8 . Pedal position sensor 8 can be configured to detect a corresponding pedal position (not shown) of a pedal of a pedal system of motor vehicle 1 , in particular a brake pedal and / or an accelerator pedal.

[0030] Furthermore, the communication device 6 is connected to a contro...

Abstract

A method for triggering self-braking in a motor vehicle (1), in which following a first collision during an accident a self-braking request signal (13) is transmitted to a brake controller (ESC) by a collision sensor unit (7) by a communications device (6) of the motor vehicle (1). The multi-collision braking requested should be initiated in the event of damage to the brake controller (ESC) that is caused by the first collision. The request signal (13) is received by a control device of the motor vehicle (1) that is disposed at a distance from the brake controller (ESC). The control device (9) then determines whether the brake controller (ESC) responds to the request signal (13). If no response of the brake controller (ESC) is detected, the self-braking is initiated by the control device (9).

Description

technical field [0001] The invention relates to a method for triggering automatic braking in a motor vehicle in the event of an accident. After the first collision, automatic braking is requested by the crash sensor unit with the aid of a request signal. Originally, the brake controller should react to the demand signal by implementing automatic braking. If the brake controller is damaged in the first collision or becomes detached from the communication bus, the brake controller will no longer be able to perform automatic braking. The invention also relates to a control device for carrying out the method according to the invention. Finally, the invention also relates to a motor vehicle having a control device according to the invention. Background technique [0002] If the motor vehicle continues on without being braked after the first collision, a further collision with another obstacle or a road participant may result. On the contrary, such a re-collision can be partic...
