A vehicle engine automatic start-stop control system and method based on vehicle-road coordination

Abstract

The invention provides a vehicle engine automatic start-stop control system and method based on vehicle-road coordination. The method includes: when temporarily parking, the communication module obtains the traffic light information, and determines whether the vehicle is at the traffic light intersection; if so, the analysis module sends the corresponding information to the vehicle start-stop module according to the red light waiting time and the information of the preceding vehicle in the same lane, combined with the preset control strategy. On the contrary, the analysis module obtains the stop time sent by the vehicle information module to determine whether the engine needs to be turned off. When the engine is turned off, if the vehicle information module detects that the vehicle needs to be started, the analysis module sends a control command to start the engine to the vehicle start-stop module. The invention realizes that when a vehicle is waiting at a traffic light intersection, it can intelligently control the start and stop of the engine according to the time of the red light and the information of whether the preceding vehicle is traveling, thereby realizing the purposes of smoother running, quick start, fuel saving and the like of the vehicle.

Description

technical field [0001] The invention relates to the technical field of automobile engine control, in particular, to a vehicle engine automatic start-stop control system and method based on vehicle-road coordination. Background technique [0002] With the country's emphasis on environmental protection, the emission regulations of domestic automobiles are becoming more and more strict. At the same time, automobile manufacturers and consumers pay more and more attention to the fuel economy of automobiles. It can effectively reduce exhaust emissions and reduce fuel consumption. The automatic engine start-stop technology refers to a system that automatically restarts the engine after the vehicle brakes and stops during driving. When the driver releases the brake pedal or the engine needs to meet other requirements (such as driving the air conditioner, etc.), the vehicle automatically restarts the engine. [0003] At present, the control logic of the engine automatic start-stop t...
