Abstract

The invention discloses a device and method for controlling idling start and stop of an engine. A controller receives signals from a battery electric quantity sensor, a gear switch, an engine speed sensor, a vehicle speed sensor, a clutch switch, a vehicle door switch, a brake pedal switch, an engine hood and an air conditioner switch and sends out signals for stalling or restarting the engine. The device and method for controlling idling start and stop of the engine have the advantages of being low in transformation cost, high in cost performance and reliability, short in development period and capable of saving energy and reducing emission.

Description

technical field [0001] The invention relates to an engine idling start-stop control device and method, belonging to the field of manual transmission motor vehicles. Background technique [0002] At present, the voice of energy saving and environmental protection is becoming stronger and stronger all over the world, and the regulations on automobile emission and fuel consumption in various countries are becoming more and more stringent. Europe has implemented Euro V emission regulations, and the United States, Japan and other countries have also implemented new emission regulations and energy-saving and emission-reduction requirements. In 2012, the number of cars in my country has reached 114 million. Traffic congestion and air pollution in big cities are becoming more and more serious. In congested cities, idling engines and cars running at low speeds will consume a lot of fuel and increase air pollution. The car idle start-stop control method can better solve these problem...
