Problems solved by technology

The frequent start and stop of the engine in a short period of time causes energy waste on the one hand, and on the other hand causes frequent engine vibrations, which affects the comfort of the vehicle
[0004] In addition, when the start-stop system is working, when the vehicle is stopped, the air-conditioning system in the car cannot work
Therefore, if this stop state lasts for too long, it will affect the air conditioning effect.

Abstract

The invention relates to a control method of a start-stop system and a start-stop system. In the method, when the engine is in a working state, the engine is allowed to stop only when all the stop conditions are satisfied, wherein the stop conditions include: the brake pedal is operated for a duration exceeding the limit time threshold or the parking brake is activated, the navigation system determines that the current traffic volume does not exceed the traffic volume threshold, the data from the environmental sensor meets the environmental conditions, the data from the air conditioning controller meets the air conditioning conditions, and the data from the vehicle speed sensor meets the vehicle speed conditions .

Description

technical field [0001] The invention relates to a control method for a start-stop system of a vehicle and the start-stop system for a vehicle. Background technique [0002] The start-stop system of the vehicle is used to suspend the engine when the vehicle is at a standstill. And when it is desired that the vehicle continues to run, the engine is started again. [0003] The existing engine start-stop system cannot obtain external information of the vehicle, such as real-time road condition information. Therefore, in urban traffic, the vehicle stops automatically after encountering a red light, and if the traffic light turns green in a short period of time, the engine needs to be started immediately. If the vehicle stops and goes slowly in congested road conditions, the engine start-stop system will frequently control the engine start / stop. The frequent start and stop of the engine in a short period of time causes energy waste on the one hand, and on the other hand causes ...
