Description

Vehicle engine automatic start-stop system and vehicle engine automatic start-stop control method

Technical field

Embodiments of the present disclosure relate to a vehicle engine automatic start-stop system and an engine automatic start-stop control method.

Background technique

At present, air pollution is a global problem. The International Health Organization issued a report saying that air pollution is carcinogenic. Therefore, how to control air pollution is a difficult problem for human beings.

The composition of air pollutants varies from country to country. The smoggy weather in many parts of China has increased, leading to a deterioration in air quality. Smog is a general term for fog and cockroaches. Sulfur dioxide, nitrogen oxides and respirable particulate matter are the main components of smog. The first two are gaseous pollutants, and the last inhalable particulate matter is an important factor in increasing the haze weather. In particular, the pollutant particles having a diameter of 2.5 μm or less are both a pollutant and a carrier of toxic substances such as heavy metals and polycyclic aromatic hydrocarbons, which are harmful, which is also the cause of air pollution.

There are two directions for the treatment of air pollution: one is to reduce pollutants into the atmosphere, and the other is to reduce the pollutants in the existing atmosphere. Embodiments of the present disclosure may reduce contaminants from entering the atmosphere.

In recent years, the number of motor vehicles in China has increased sharply, and motor vehicle pollution has become increasingly serious. Vehicle exhaust emissions have become the main source of air pollution in large and medium-sized cities in China, which has brought tremendous pressure on urban and regional air quality. According to some research reports, under actual driving conditions, the concentration of volatile organic pollutants (VOCs) and benzenes in vehicles in cold start and idle conditions is much higher than that during normal driving. At a speed of 40-60 km/h, the VOCs and benzene content in the exhaust gas are relatively low. The preliminary results of the formation mechanism and source analysis of regional atmospheric pollution in the Institute of Atmospheric Physics of the Chinese Academy of Sciences show that the main source of PM2.5 in the heavy pollution period in Beijing in January 2013 and February 2014 was Motor vehicles, coal, industrial and dust are about 42%, 28%, 13% and 12% respectively; while in clean time, coal accounts for 45% and motor vehicles only 13%.

The engine's Start-Stop System is a system that controls the engine's flameout/ignition. The core is to automatically control the engine's flameout/ignition according to the speed and stop time during driving, minimizing the fuel consumption and reducing the fuel consumption during idle. Emissions, mainly for urban traffic Wait for the signal or traffic jam. After the engine is turned off, the battery can also replace the engine to power the cooling fan and the car air conditioner.

Simply put, the engine automatic start-stop system allows the car to "sleep" when the vehicle is temporarily parked, and it can respond quickly when it needs to start (the engine start-up time is about 0.4 seconds, which hardly affects the normal start), and the automatic transmission and This system can be equipped for manual transmission models. The function of this system is to automatically extinguish the engine during the waiting time of the car, to minimize the fuel waste and air pollution caused by the engine idle speed.
