The invention provides an automobile engine automatic start-stop control system and method based on automobile-road cooperation. The method comprises the steps that during temporary parking, a communication module obtains traffic light information and judges whether a vehicle is located at a traffic light intersection or not, and if so, an analysis module sends a corresponding control instructionto a vehicle start-stop module in combination with a preset control strategy according to red light waiting time and front vehicle information on the same lane; otherwise, the analysis module obtainsstop time sent by the vehicle information module to judge whether the engine needs to be shut down. When the engine is shut down, if the vehicle information module monitors that the vehicle needs to be started, the analysis module sends a control instruction for starting the engine to the vehicle start-stop module. When the vehicle waits at the traffic light intersection, the engine can be intelligently controlled to be started and stopped according to the time of the red light and the information whether the front vehicle advances or not, and purposes that the vehicle runs more stably and isstarted quickly, fuel oil is saved and so on are achieved.
Description
technical field [0001] The present invention relates to the technical field of automobile engine control, in particular, to an automobile engine automatic start-stop control system and method based on vehicle-road coordination. Background technique [0002] As the country attaches great importance to environmental protection, domestic automobile emission regulations are becoming increasingly strict. At the same time, automobile manufacturers and consumers are paying more and more attention to automobile fuel economy. Engine automatic start-stop technology is increasingly equipped on various automobiles. This technology It can effectively reduce exhaust emissions and reduce fuel consumption. The automatic engine start-stop technology refers to a system that automatically turns off the engine after the vehicle brakes during driving, and restarts the engine automatically when the driver releases the brake pedal or the engine needs to meet other requirements (such as driving the...
