Vehicle brake release control system and method and vehicle

Abstract

The invention discloses a vehicle brake release control system and method and a vehicle, the system comprises a storage battery, a tow hook device, a vehicle control unit, a brake system, a lighting system and a double-source steering system, the tow hook device comprises a tow hook, a tow hook base, a power switch and a signal control switch used for sending an unlocking signal, a mounting groove used for mounting the tow hook is formed in the tow hook base, the power switch and the signal control switch are arranged in the mounting groove, the power switch is located above the signal control switch, and the two wiring ends of the power switch are connected with the storage battery and the vehicle control unit respectively. Two terminals of the signal control switch are respectively connected with the storage battery and the whole vehicle controller, and the braking system, the lighting system and the double-source steering system are respectively connected with the whole vehicle controller. According to the control system and method, braking of the whole vehicle can be forcibly relieved, a user is reminded of braking relieving through the lighting system, and it is guaranteed that the vehicle can be dragged.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle brake release control system and method thereof, and a vehicle. Background technique [0002] The increasingly serious problems of energy crisis, environmental pollution and greenhouse effect have made new energy vehicles, especially pure electric vehicles, an inevitable trend of change in the automotive industry. Pure electric vehicles have the advantages of energy saving, environmental protection, economy, high NVH quality, simple structure, and strong power, and have attracted extensive attention from scientific research institutions and enterprises. [0003] Pure electric vehicles use power batteries as energy sources and motors as power sources. High integration is one of its characteristic attributes. The application of pure electric vehicle smart cockpit controller (CDC) is one of the representatives of highly integrated components. The functions in the cockpit ...

Problems solved by technology

[0003] Pure electric vehicles use power batteries as energy sources and motors as power sources. High integration is one of its characteristic attributes. The application of pure electric vehicle smart cockpit controller (CDC) is one of the representatives of highly integrated components. The functions in the cockpit , such as the activation and release of electronic parking (EPB), the activation and release of P gear, charging control, creeping on and off, etc., are all integrated into this device. In case of damage, the whole vehicle will keep the actions that have been performed when the power was turned off last time, and the functions cannot be set or changed, especially the brakes cannot be released, and trailer maintenance cannot be performed. Forced dragging may damage the gearbox and other brakes. system, affecting the use of vehicle functions
