Control method, device and system for automatic start-stop system of vehicle

Abstract

The invention discloses a controlling method, a controlling device and a controlling system of automatic stop-start system in car. The controlling method includes: acquiring the parameter of the air conditioner in car, if the driving parameter of car meets the condition of automatic stop-start model. The mentioned driving parameter should at least include the condition of engine, the speed of carand the rest electricity of battery. The parameter of the air conditioner in car should at least include the stop-start parameter of the air conditioner in car, refrigeration and heating parameter, temperature value, humidity value and the evaluation value of air quality. The stop-start parameter of the air conditioner in car should be under the condition of staring. In addition, by comparing theparameter of air conditioner and the preset parameter of environment, people should judge whether the parameter of air conditioner meets the condition of automatic stop-start model. If the parameter of air conditioner meets the condition of automatic stop-start model, the car is allowed to enter into the automatic stop-start model. Or else, the car is not allowed to enter into the automatic stop-start model. The controlling method for automatic stop-start system in car solves the problems of the car's entering into the automatic stop-start model and the uncomfortable feelings of passengers, when the air conditioner in car is directly closed.

Description

Technical field [0001] The present invention relates to the field of vehicles, and in particular to a control method, device and system of an automatic start-stop system of a vehicle. Background technique [0002] In the prior art, automobile energy-saving technologies mainly include start-stop technology and hybrid technology. The start-stop technology means that when the car is on a congested road, waiting for a green light, or when the speed is zero, the engine can automatically stop and start at any time. Start-stop technology can reduce car exhaust emissions within the city, and can reduce car fuel consumption. [0003] For models equipped with automatic transmissions, the automatic start-stop system involved in the start-stop technology works as follows: During the driving of the vehicle, the driver only needs to directly depress the brake pedal, and the engine will automatically turn off after the vehicle is completely stopped for about two seconds. , Keep depressing the br...
