Engine start-stop system and engine start-stop control method

Abstract

The invention provides an engine start-stop system, which includes a start-stop controller, a storage battery, a starter, a stop trigger data detection module, a start trigger data detection module and a vehicle body communication network. According to the engine start-stop system of the present invention, a real-time road condition detection module for detecting the current vehicle position and the nearest traffic light position in the direction of vehicle travel is added to the stop trigger data detection module, and " The distance between the current vehicle position and the nearest traffic light position in the direction of travel of the vehicle is less than or equal to the preset shutdown distance", the start-stop controller prohibits the engine from shutting down when the above-mentioned distance is greater than the preset shutdown distance, thereby Ineffective start and stop are avoided, so as to realize the fuel saving of the engine start and stop system and reduce the emission of harmful gases. In addition, the invention also provides an engine start-stop control method.

Description

technical field [0001] The invention relates to the technical field of vehicle engine start and stop, in particular to an engine start and stop system and an engine start and stop control method. Background technique [0002] With the increasing number of vehicles in our country's cities, traffic jams are becoming more and more serious, and vehicles consume more and more fuel when they are in traffic jams and idling, which leads to a decline in fuel economy and increases the emission of harmful gases, causing urban air pollution. Environmental degradation. [0003] In order to solve the above problems, the vehicle engine start-stop system came into being. The engine start-stop system is a micro-hybrid technology. When starting the car, start the engine quickly, which can effectively reduce the emission of harmful gases and reduce fuel consumption in urban conditions. [0004] At present, many cars with start-stop systems have been put on the market, and most of them realiz...
