Abstract

The invention discloses a flameout anti-slipping protection and control method for an engine starting and stopping system. When the engine starting and stopping system of a vehicle is within the flameout slipping protection range and the engine starting and stopping system detects that the vehicle might slip down a ramp, protection is conducted in one or two ways: 1, an electronic parking braking (EPB) system controller sends a braking request through a vehicle CAN bus to ask an electronic stability program to provide braking pressure for the system; 2, the engine starting and stopping system controls a motor of an execution mechanism to rotate so as to apply braking force, and then parking is executed. By the adoption of the technical scheme, safety performance is improved; for the vehicle provided with the engine starting and stopping system, when the starting and stopping system is in the working state, the vehicle stalls and stops on the ramp and potential safety hazards occur, an EPB system can conduct protection; system cost is low; no peripheral part needs to be additionally arranged, protection is achieved based on the original system, and system cost is not increased.

Description

technical field [0001] The invention belongs to the technical field of motor vehicle brake system structure and control method. The motor vehicles include but not limited to automobiles and hybrid vehicles. More specifically, the present invention relates to a flame-out anti-slope protection control method of an engine start-stop system. Background technique [0002] With the rapid development of the automobile industry, more and more people begin to enjoy the convenience it brings, but at the same time it brings more pressure to the ecological environment. consumer concern. When encountering a traffic jam or waiting for a traffic light, people are used to letting the car be in the idling condition. The car in the idling condition will produce a certain amount of fuel consumption and exhaust emissions. Emissions. [0003] However, in the working state of the engine start-stop system, after the engine is shut down and the flame is turned off, if the vehicle stops on the s...
