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 is shown having an arrangement 100 according to an embodiment of the invention. The vehicle 10 includes a parking brake system 50 having a spring-loaded brake cylinder (not shown) operable to release the parking brake 50 against spring force using pressurized air, and the parking brake system 50 One or more drive wheels 11 of the vehicle 10 are configured to brake. However, the parking brake system 50 may be configured to control not only the brake actuators on the driven wheels 11 but also the brake actuators on the non-driven wheels 12 of the vehicle 10 . To this end, corresponding connections 60 are provided, which may comprise wiring (eg 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 based on wheel slip of one or more wheels 11 of the vehicl...

Abstract

An apparatus (100) for controlling traction of a vehicle (10) is disclosed, wherein the vehicle (10) includes a parking brake system (50) having a spring-loaded brake cylinder operable to The parking brake is released against a spring force using pressurized air, and the parking brake system (50) is configured to brake one or more drive wheels (11) of the vehicle (10). The device includes a data interface module (110) and a braking control module (120). The data interface module (110) is configured to receive input information (115) based on wheel slip of one or more wheels (11) of the vehicle (10). The brake control module (120) is configured to determine wheel slip based on the received information, and to control the parking brake system (50) to maintain wheel slip below a threshold, thereby controlling traction of the vehicle (10).

Description

technical field [0001] The present invention relates to an apparatus and method for traction control of a vehicle, and more particularly to a method for overriding a driver's parking brake request with respect to wheel slip for a commercial vehicle. Background technique [0002] Many vehicles are required to have two braking systems, one service brake for normal braking action and one parking brake. The two braking systems are independent to ensure the vehicle stops safely. If the service brakes fail, the parking brake acts as a secondary brake. For commercial vehicles, the parking brake is typically operated by pressurized air, and may include a spring-loaded brake cylinder, wherein 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 force of the spring. The permanently acting spring force ensures that the vehicle can only move duri...
