Abstract
The invention relates to a high-efficiency operation strategy for a vehicle. The strategy gives overall consideration to the distance between a current position of the vehicle and a traffic post and the change period of traffic lights on the basis of considering driver's intention and operation condition of the vehicle. Through the optimization and calculation of high-efficiency operation speed of the vehicle, the strategy obtains the real-time high-efficiency operation speed of the vehicle, and timely reminds a driver of correcting the operation strategy, enables the rotating speed of a vehicle driving device to be within a high-speed operation section in as much time as possible, improves the economical performance of the vehicle to a greater extent, and reduces the probability of traffic accidents. When the strategy is used in the technical field of pure electric vehicles, the strategy will effectively increase the endurance mileage of the vehicle, and lays a better theory foundation for the safe operation of the vehicle and the high-efficiency operation of an intelligent vehicle.
