Method for the automated electronic control of a braking system and electronically controllable braking system in a utility vehicle

Abstract

The invention relates to a method for the automated electronic control of a braking system (100) in a vehicle (200), having at least the following steps: - reading a request signal (S1) for the automated electronic triggering of actuators (1, 50, 52, 53) in the vehicle (200), wherein at least one of the actuators (1, 50, 52, 53) has an influence on an actual longitudinal dynamic of the vehicle (200), and requests (aSoll, vSoll, RSoll) to establish an automatically requested target longitudinal dynamic of the vehicle which are to be implemented by the actuators (1, 50, 52, 53) are transmitted via the request signal (S1); - plausibility-checking the request signal (S1) to determine whether the requests (aSoll, vSoll, RSoll) to establish the automatically requested target longitudinal dynamicof the vehicle are being or can be fully and correctly implemented by the actuators (1, 50, 52, 53); - defining a correction deceleration (zKorr) and / or a correction speed (vKorr) if at least one ofthe requests (aSoll, vSoll, RSoll) is not or cannot be fully and correctly implemented, to specify corrective braking, the correction deceleration (zKorr) and / or the correction speed (vKorr) being determined depending on the request (aSoll, vSoll, RSoll) which is not or cannot be fully and correctly implemented; - requesting the corrective braking of the vehicle (200) depending on the correction deceleration (zKorr) and / or on the correction speed (vKorr) to put the vehicle (200) into a safe state.

Description

technical field [0001] The invention relates to a method for automated electronic control of a brake system and to an electronically controllable brake system in a commercial vehicle, in particular in an automated controllable commercial vehicle. Background technique [0002] In vehicles, in particular commercial vehicles, with a pneumatic brake system, in particular designed as an electronic service brake system (EBS), an electronically controlled valve, such as a relay valve, can be actuated by the control unit (ECU) for regulating the brake pressure. or the axle modulator, and then the electronically controlled valve pneumatically regulates the brake pressure to the brake cylinders of the service brakes of the braking system as a function of the requested target acceleration of the vehicle. Depending on the driver's actuation of the brake force regulator or brake value transmitter via the brake pedal, the control of the brake pressure is superimposed on the electronic con...
