Problems solved by technology

However, the parking brake can only be activated via a typically monostable actuating element
Consequently, the driver is in some cases unable to activate the parking brake only for a single axle or separately for different parts of the vehicle, such as the trailer or trailer
It is also possible, for example, that a part of the actuating element would be damaged due to emergency or complete braking or, for example, that the driver loses consciousness, so that the parking brake can no longer be applied
The driver cannot operate the parking brake from an area other than the driver's cab where the operating element is located due to limitations in the operation via the individual operating elements

Embodiment Construction

[0036] According to the figures, an electronic parking brake system 1 of a motor vehicle (not shown here in further detail) comprises a brake actuator that can be moved into a braking position for applying braking forces to the wheels of the motor vehicle (not shown here) 2. An actuating element 3 for actuating the brake actuator 2 and in the form of a monostable button that can be manually actuated by the user, electronically communicates with the actuating element and serves to actuate a control connected to the brake actuator 2 Control unit 4 for valve 5. In this case, the control unit 4 has an interface 6 for communicating with a plurality of external control systems 7 including sensors and / or actuators which define the operating state of the motor vehicle.

[0037] In this case, these external control systems include a height adjustment system 7a, a driver assistance system 7b, a service brake system system 7c, a transmission system 7d and a body construction module 7e. ...

Abstract

The present invention relates to an electronic parking brake system (1) of a motor vehicle, comprising a brake actuator (2), which can be moved into a braking position for applying braking force to a wheel of the motor vehicle, a manually actuatable actuation element (3) for activation of the brake actuator (2) by a user, a control unit (4) electronically communicating with the actuation element (3) to activate a control valve (5) connected to the brake actuator (2), wherein the control unit (4) has an interface (6) for communication with an external control system (7) comprising actuators and / or sensors defining the operating state of the motor vehicle, as well as calculation instructions for evaluation of a data packet (8) sent by the control system (7), to activate the brake actuator (2) of the parking brake system (1) in the event of appropriate evaluation of the data packet (8). The invention further relates to a motor vehicle having an electronic parking brake system (1) of this type, as well as to a method for operating a parking brake system (1) of this type.

Description

technical field [0001] The invention relates to an electronic parking brake system for a motor vehicle, comprising a brake actuator that can be moved into a braking position for applying a braking force to the wheels of the motor vehicle, a brake actuator that can be manually operated by the user An actuating element of a brake actuator, a control unit in electronic communication with the actuating element for actuating a control valve connected to the brake actuator. Furthermore, the invention relates to a motor vehicle, preferably a truck, having such a parking brake system, and to a method for operating the parking brake system. Background technique [0002] The field of application of the invention extends to motor vehicles, preferably trucks, having an electronically actuatable parking brake system. In this case, the request is transmitted to the electronic control unit of the parking brake system by actuating or deflecting the preferably monostable actuating element b...
