Problems solved by technology

As a result, the driver's experience with controlling braking force using the parking brake is limited - especially when the driver is trying to hold the vehicle steady while actuating the parking brake lever
In this case stability is often lost and security risks are increased
[0006] On the other hand, vehicle systems without acceleration traction control are also very demanding on the driver
In particular, slippery road conditions not only pose a safety risk, but may likewise lead to delivery delays and additional operating costs
[0007] While slip control for braking is mandatory in many regions, traction control is often optional and therefore not implemented - even considering the increased safety risks and loss of transport robustness

Embodiment Construction

[0029] figure 1 A commercial vehicle 10 having a device 100 according to an embodiment of the invention is shown. The vehicle 10 includes a parking brake system 50 having a spring-loaded brake cylinder (not shown) that is operable to use pressurized air to overcome the spring force to release the parking brake 50, and the parking brake system 50 It is configured to be able to brake one or more driving wheels 11 of the vehicle 10. However, the parking brake system 50 may be configured to control not only the brake actuators on the driving wheels 11 but also the brake actuators on the non-driving wheels 12 of the vehicle 10. To this end, a corresponding connection 60 is provided, which may include wiring (for example, a vehicle communication bus) and / or hydraulic and / or pneumatic lines.

[0030] The device 100 includes a data interface module 110 and a brake control module 120. The data interface module 110 is configured to receive input information 115 according to wheel slip of...

Abstract

An apparatus (100) for controlling a traction of a vehicle (10) is disclosed, wherein the vehicle (10) comprises a parking brake system (50) with a spring-loaded brake cylinder operable to release theparking brake against a spring force using pressurized air and the parking brake system (50) is configured to brake one or more driven wheels (11) of the vehicle (10). The apparatus includes a data interface module (110) and a braking control module (120). The data interface module (1 10) is configured to receive input information (115) depending on a wheel slip of the one or more wheels (11) ofthe vehicle (10). The braking control module (120) is configured to determine the wheel slip based on the received information and to control the parking brake system (50) to keep the wheel slip belowa threshold value, thereby controlling the traction of the vehicle (10).

Description

Technical field [0001] The present invention relates to a device and method for traction control of a vehicle, and more particularly to a method for overriding a driver's parking brake request for a commercial vehicle regarding wheel slip. Background technique [0002] Many vehicles need to have two braking systems, one is the service brake for normal braking action and the other is the parking brake. The two braking systems are independent to ensure that the vehicle stops safely. If the service brake fails, the parking brake serves as an auxiliary brake. For commercial vehicles, the parking brake is usually operated by pressurized air and may include a spring-loaded brake cylinder, where the spring automatically engages the brake if sufficient air pressure is not applied. The parking brake is released by applying compressed air to a spring-loaded brake cylinder to overcome the spring force. The permanently acting spring force ensures that the vehicle can only be moved during ...
