Problems solved by technology

Manual hill start requires the driver to have proficient accelerator, clutch and brake coordination technology to start smoothly and ensure that the vehicle does not slide backwards. This method of hill start has relatively high requirements for the driver, and it is prone to accidents if the operation is improper. Dangerous; automatic hill start is electronically controlled to realize the automatic control of the generation and release of the vehicle's hill start brake, but the current automatic hill start cannot automatically identify whether the vehicle is on an uphill, downhill or flat ground, so it is necessary The driver manually triggers the switch for automatic hill start

Embodiment Construction

[0036] The method for assisting hill start based on the ABS system and the system using the method will be described in detail below in conjunction with the accompanying drawings.

[0037] The method of the present invention is combined in a specific overall system. In the present invention, the system is an auxiliary hill start system using the described auxiliary hill start method. The structural diagram of the system is as follows figure 1 shown. exist figure 1 In , the lines intertwined with each other represent the electric circuit, and the black straight line represents the gas path.

[0038] refer to figure 1 , the composition of the auxiliary hill start system on the air circuit includes: a brake chamber 2, an ABS electromagnetic regulating valve 4, a two-way check valve 11, a brake valve 6, an air storage tank 7 and an auxiliary hill start solenoid valve 10, Wherein, the ABS electromagnetic regulating valve 4 is used to adjust the braking force of each wheel of the...

Abstract

The invention discloses an aiding hill starting method based on an anti-lock braking system (ABS) and an aiding hill starting system using the method. The method comprises a step of judging the launching of aiding hill starting, wherein the situation that a vehicle can be in an aiding hill starting launching state is confirmed, a step of aiding hill braking, wherein a pressure maintaining process is carried out on a brake air chamber, and a step of aiding the hill starting, wherein an ABS pressure reducing signal is sent to reduce the pressure in the brake air chamber to zero, and a clutch is completely combined. The system can judge that the vehicle is located in the flat ground or the slope by obtaining vehicle velocity, acceleration, tap position or foot braking information, the aiding hill starting system is automatically started to control the hill starting according to a judgment result, a driver does not need to manually operate, unnecessary backward sliding times can be reduced, and unnecessary accidents are avoided.

Description

technical field [0001] The invention belongs to the technical field of automobile braking, and in particular relates to an auxiliary slope start system and method based on an ABS system. Background technique [0002] ABS system (Anti-lock Braking System) is an electronic system that monitors and controls vehicle speed during braking. Its task is to prevent the wheel from locking due to excessive braking force (especially on low-adhesion roads), so that the lateral force can be maintained even with full braking, so as to ensure driving stability, vehicle steering control and main function. Optimal effect of trailer brake coordination. The ABS system works through the conventional braking system, which can improve the active safety of the vehicle. [0003] At present, there are two main methods of starting on a hill: manual and automatic. Manual hill start requires the driver to have proficient accelerator, clutch and brake coordination technology to start smoothly and ensu...
