Problems solved by technology

However, since this design embeds the functions of the engine start-stop control system in the EMS, the control strategy, algorithm, calibration, and verification of the system are too complex and the time period is too long (usually not less than 80 weeks), and the calibration cost is too high. Advanced factors restrict the promotion of embedded solutions

Abstract

The invention discloses an independent type engine start and stop control system and a control method thereof. The control system comprises an EMS, an EPS, a storage battery, a generator, a starting engine, a vacuum sensor, vehicle switches, vehicle loads and an engine start and stop control module. According to the independent type engine start and stop control system, the engine start and stop control system is separated from the EMS and forms a special control module, the special module collects information of multiple sources and is communicated with the engine through a CAN bus under the calibration conditions of a vehicle, then the engine is started or stopped, and therefore the purpose of fuel conservation is achieved. The independent type engine start and stop control system and the control method thereof have the advantages that the basic framework of the electrical system of the vehicle is not changed, the special module is communicated with the engine, calibration verification is simple, the development period is short, calibration cost is low, hardware cost is lowered, and the control method is suitable for multiple standards of vehicles. According to the engine start and stop control method, the independent engine start and stop control module is used for starting and stopping the engine automatically, the hardware cost is lowered, and safety and reliability are guaranteed.

Description

technical field [0001] The present invention relates to an automobile control system and its control method, in particular to an independent engine start-stop control that can automatically stop when the vehicle is coasting, stops and the engine is running at idling speed, and can automatically restart when the vehicle starts system and its control method. Background technique [0002] At present, with the increase in the number of automobiles, the impact of automobile fuel consumption and exhaust emissions on the environment is becoming more and more obvious. In order to reduce fuel consumption and reduce air pollution, many new technologies have been invented. For example, the engine stops or The main design idea of ​​this engine start-stop control system is to integrate the traditional control strategy and hardware into the engine EMS (Engine Management System, engine management system), according to the driver's driving intention, Various information such as the working...
