Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings.

[0022] One of the application examples of the present invention, its hybrid braking system structure diagram is shown in Figure 1, the electric vehicle hybrid braking system includes a pneumatic braking subsystem and a regenerative braking subsystem. The pneumatic brake subsystem includes a brake pedal 14 and a pressure control valve 13 associated with it. The right side of the pressure control valve 13 is connected to the air storage tank 12 and the air compressor 11 as a pressure maintaining mechanism. The left side of the pressure control valve 13 is adjusted by pressure. The valve 16 is connected to the ABS control valve 18, and the ABS component group includes the ABS controller 9, the wheel speed sensor 10, the ABS control valve 18 and the failure alarm device 8; the regenerative braking system includes the motor 5 with the regenerative braking function, and the m...

Abstract

The invention is concerned with equipment to keep the safety of vehicle braking system with regenerative braking function, belonging to protecting equipment technology field for vehicle braking protecting equipment. It relates to alarm light of braking fault feedback, relay, journey switch, braking pattern selecting switch, melody valve of braking feedback and braking controller. The journey switch is under the footplate of vehicle braking system connecting with relay and the relay is between the melody valve of braking feedback and braking controller in series. The controller judges the position of footplate. When the position of footplate is less than 80 degree, it starts the pattern of braking feedback to feedback the braking until stopping the vehicle, and during the period, if the wheel locks or the position of footplate is larger than 80 degree, it starts the conversion of braking pattern. It callbacks braking energy as much as possible, to enhance the economy benefit of whole vehicle to prevent locking of wheel and increase the dependability of braking system.

Description

technical field [0001] The invention relates to a safety guarantee device of an automobile braking system with a braking energy feedback function and a control method thereof, and belongs to the technical field of protection devices for automobile braking devices. Background technique [0002] Automobile braking energy regeneration technology is of great significance for further reducing automobile energy consumption and emissions, and alleviating the world's energy crisis and environmental pressure. Regenerative braking technology will be widely used in energy-saving vehicles, including hybrid electric vehicles, pure electric vehicles, and fuel electric vehicles. [0003] Compared with cars with traditional braking systems, the braking system of cars with regenerative braking has changed in the structure and mechanism of the braking system, which will affect the braking effect and safety of the car. In order to maximize the recovery of braking energy, the braking system be...
