Embodiment Construction

[0044] figure 1 A vehicle data network 1 of a commercial vehicle is shown schematically using a block diagram, comprising a powertrain CAN data bus 6 which is connected in a manner known per se to a parking brake, which may be electropneumatically actuated The control device 4 (electric parking brake), the control device 5 of the electronic service brake system and also further components 7 which can be connected to the CAN data bus 6 are connected. The connections between components 2, 4, 5 and 7 and the CAN data bus are schematically shown by solid connecting lines.

[0045] A manually operated emergency off switch 2 mounted in the cab is also provided. The emergency off switch 2 is further connected to a battery disconnect switch 3 via a signal line. The signal lines are shown by the solid connecting lines between 2 and 3. The battery disconnect switch 3 is designed to disconnect the entire power supply to all control devices after a settable run time, in other words to...

Abstract

The invention relates to a method for applying an electric parking brake device of a motor vehicle, in particular a commercial vehicle, which is equipped with a manually operated emergency closing operating element and a disconnecting device for operating the emergency closing due to Operation of the element disconnects the voltage supply device from the on-board electrical system. The method comprises the steps of: (a) when the speed of the motor vehicle is not greater than a predetermined first threshold value (v1) when the emergency shutdown operating element is operated: (a1) applying the electric parking brake, and (a2) disconnecting the setting the delay time to a first value; and (b) when the speed of the motor vehicle is greater than a predetermined first threshold value (v1) when the emergency closing operating element is operated: (b1) setting the delay time to disconnect the device to a second value, The second value is greater than the first value, (b2) sending a braking request to the electric service brake, and (b3) applying the electric parking brake once the speed of the motor vehicle is less than or equal to a predetermined second threshold.

Description

technical field [0001] The invention relates to a method for applying an electric parking brake system of a motor vehicle, in particular a commercial vehicle, which is equipped with a manually operated emergency closing operating element and a disconnecting device for emergency closing due to Actuation of the operating element disconnects one or more voltage supply means from the on-board electrical system. The invention also relates to a control device for controlling an electric parking brake device and for controlling a disconnection device for disconnecting a voltage supply device from an on-board electrical system. Background technique [0002] Commercial vehicle braking systems include a service braking system and a parking braking system that are usually controlled independently of each other, either pneumatically or electrically. The parking brake system, hereinafter also referred to as the parking brake or the parking brake system, generally comprises a spring-load...
