Abstract

An engine start and stop control system in the technical field of automobile electronic control comprises an intelligent sensory control system, an engine management system, an energy storage power source, an electric generator, a starting motor, a vehicle-mounted electric appliance and a current sensor of the vehicle-mounted electric appliance. Through receiving and processing voltage signals, temperature signals and current signals of the energy storage power source, the intelligent sensory control system accurately estimates state parameters, including dump energy, starting minimum voltage and a battery life state, of a current energy storage system, current related information from the engine management system and the vehicle-mounted electric appliance are synthesized, and energy optimization and service life optimization intelligent algorithms are adopted for dynamically adjusting operation condition points of the engine and for controlling start and stop of the engine. The engine start and stop control system is reasonable in design and suitable for whole vehicle electric energy management and the engine start and stop control, service life of the vehicle-mounted energy storage unit is further prolonged, energy consumption of the engine is reduced, and emission is reduced.

Description

technical field [0001] The invention relates to an engine start-stop control system in the technical field of automobile electronic control, in particular to an engine start-stop control system with an intelligent sensor control system. Background technique [0002] One of the most important problems to be solved by automobile energy-saving technology is to reduce the environmental pollution caused by fuel consumption and exhaust emissions. According to the survey, the average ratio of car driving time to the time spent waiting for red lights or traffic jams is 3:1, and some cities even reach 5:2. As more than ten million new cars flood onto the road every year, urban roads will become more congestion. The engine start-stop system is the most rapidly developed automotive environmental protection technology in recent years, especially suitable for stop-and-go urban road conditions. The engine start-stop system can eliminate idling, automatically shut down the engine, and re...
