Problems solved by technology

[0002] At present, the braking system of all-terrain vehicles mainly uses the hand brake operating system to control the braking of the two front wheels, and the foot brake system controls the braking of the two rear wheels. The dynamic pump generates fluid pressure, and then controls the brake of the front wheel through the front wheel splitter to complete the front wheel braking; the hydraulic pump of the foot brake system is connected to the foot brake shunt pump to generate fluid pressure to control the rear wheel brake. Foot brake braking not only leads to poor experience for the driver, but also has a high degree of wear and tear on parts

Embodiment Construction

[0043] Chinese and English explanation:

[0044] The Chinese name of CVT is continuously variable transmission (English: Continuously Variable Transmission), which is a kind of automobile transmission;

[0045] The Chinese name of ECU is engine controller (English: Engine control unit), which is an electronic device that controls the operation of various parts of the internal combustion engine;

[0046] The combined speed of the CVT system is the speed at which the belt drives the driven wheel to rotate.

[0047] In view of this, the core of the present invention is to provide a vehicle downhill braking system, which can not only effectively reduce unnecessary wear and tear of parts, but also improve the experience of the driver.

[0048] Another object of the present invention is to provide a method for braking a vehicle downhill.

[0049] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be fu...

Abstract

The invention discloses a vehicle downhill braking system and a vehicle downhill braking method, the vehicle downhill braking system comprises an angle sensor, a controller and an ECU, the angle sensor is used for detecting a downward inclination angle of a vehicle body of a vehicle; the controller is used for receiving the inclination angle, and when the inclination angle is within a preset angle range, the controller controls and obtains the rotating speed of the engine; when the rotating speed is smaller than the combined rotating speed of the CVT system, a rotating speed adjusting instruction for adjusting the rotating speed is generated; the ECU is used for receiving the rotating speed adjusting instruction and adjusting the rotating speed according to the rotating speed adjusting instruction till the rotating speed is equal to or larger than the combined rotating speed of the CVT system. Compared with the prior art, the system carries out engine braking by adjusting the rotating speed of the engine, a hand brake or a foot brake does not need to be adopted for braking, unnecessary part abrasion can be effectively reduced, and meanwhile the experience pleasure of a driver can be improved.

Description

technical field [0001] The invention relates to the technical field of vehicle braking, in particular to a vehicle downhill braking system and a braking method. Background technique [0002] At present, the braking system of all-terrain vehicles mainly uses the hand brake operating system to control the braking of the two front wheels, and the foot brake system controls the braking of the two rear wheels. The dynamic pump generates fluid pressure, and then controls the brake of the front wheel through the front wheel splitter to complete the front wheel braking; the hydraulic pump of the foot brake system is connected to the foot brake shunt pump to generate fluid pressure to control the rear wheel brake. Foot brake braking not only leads to poor experience for the driver, but also has a high degree of wear and tear on parts. [0003] Therefore, how to reduce unnecessary wear and tear of parts while improving the experience of the driver is a technical problem urgently need...
