Control method, device and equipment for automatic start and stop of vehicle and product

Abstract

The invention provides a vehicle automatic start-stop control method, device, equipment and a product, and relates to the technical field of vehicle control, and the method comprises the following steps: obtaining signal lamp information and traffic state information, wherein the signal lamp information comprises a traffic signal at the current moment and remaining time of the traffic signal, and the traffic state information is generated based on state information of a main vehicle HV, or the state information of the main vehicle HV and state information of a surrounding vehicle RV, or the state information of the main vehicle HV, the state information of the surrounding vehicle RV and road condition information; when the vehicle is in the stop state, adjusting the trigger time of automatic start and stop of the engine based on the signal lamp information and the traffic state information or based on the traffic state information; and carrying out automatic start-stop control on the engine based on the trigger time. According to the invention, the trigger frequency of automatic start and stop can be reduced, the service life of the engine is prolonged, the probability of occurrence of traffic accidents is reduced, and meanwhile, better driving experience is brought to a driver.

Description

technical field [0001] The present invention relates to the technical field of vehicle control, in particular to a control method, device, equipment and product for automatic start and stop of vehicles. Background technique [0002] Automatic engine start and stop is a system that automatically turns off the engine when the vehicle stops temporarily during driving, and automatically restarts the engine when it needs to continue moving forward. For example, when the vehicle needs to stop due to traffic congestion and other reasons, the driver will step on the brake pedal and take off the gear. After the vehicle stops for a few seconds, the automatic start-stop system of the vehicle will start self-checking. When idling and no gear is engaged, the reading of the wheel speed sensor is zero, and the vehicle has enough power for the next start, the engine is controlled to stop working. When the vehicle needs to continue moving, the driver only needs to release the brake pedal, ...
