Abstract

The invention provides a simulation system and a simulation method for verifying idling start and stop control on an engine. The simulation system comprises a vehicle model, a traffic flow model, a first driving control module and a start and stop control module, wherein a real-time traffic status simulation model is pre-stored in the traffic flow model; a first driving control instruction is generated by the first driving control module according to the real-time traffic status simulation model, a preset safe driving strategy and acquired simulation vehicle speed information; simulation vehicle speed information and vehicle status information are generated by the vehicle model according to the first driving control instruction, and the vehicle module outputs the two kinds of generated information to the start and stop control module, and outputs the simulation vehicle speed information to the first driving control module; a start and stop control instruction is generated by the start and stop control module according to the vehicle status information and the simulation vehicle speed information; and the vehicle module carries out the specific idling start and stop operation according to the start and stop control instruction, and outputs an operation result. By the technical scheme, the verification accuracy on an engine idling start and stop control algorithm can be effectively improved.
