Embodiment

[0047] The implementation of the present invention will be described below through specific examples. In this embodiment, dual-brake control is performed on an automatic driving sweeper, a special operation vehicle that needs to be driven at a low speed. The mechanical brake mechanism of the double brake control system in this embodiment can be but not limited to an electromagnetic brake mechanism.

[0048] The electronic brake mechanism of the double brake control system in this embodiment can adopt, but is not limited to, an energy consumption brake mechanism.

[0049] The low-speed self-driving sweeping vehicle of this embodiment is equipped with an intelligent controller. The intelligent controller is equipped with a vehicle control decision-making module, a vehicle information collection module, and a braking control system. The brake control system controls the hardware of the intelligent controller to generate control signals to control the electromagnetic brake mechan...

Abstract

The invention discloses a double-brake control method and system suitable for a low-speed automatic driving special operation vehicle, and is used for avoiding the defects of a single-brake system. Meanwhile, the braking performance of the vehicle can be improved through multiple sets of braking systems, and the reliability and the safety of the braking systems can be improved through hot backup of the multiple sets of braking systems; meanwhile, the invention further provides a method for judging how to control starting and stopping of the braking subsystems according to the vehicle braking requirements. Through the method, switching of the two braking systems can be controlled timely, efficiently and accurately.

Description

technical field [0001] The invention belongs to the control technology of automatic driving vehicles, and in particular relates to a double brake control method and system suitable for low-speed automatic driving special operation vehicles. Background technique [0002] At present, the vast majority of special operation vehicles (such as sprinklers, etc.) require manual driving and operation, which requires a lot of manpower and financial resources. The rapid development of autonomous driving technology has put forward higher requirements and challenges for the structure, control method and safety performance of the braking system, and has continuously promoted the technical improvement and innovation of all aspects of the braking system. [0003] The frictional contact mode of the mechanical brake wears the brake mechanism a lot, and the brake mechanism needs to be maintained frequently. However, self-driving vehicles (especially in the low-speed automatic driving state, s...
