Power system control method, system and vehicle of extended-range vehicle

Abstract

The invention provides a power system control method, system and vehicle of an extended-range vehicle, and relates to the technical field of vehicles. The power system control method of the extended-range vehicle according to the present invention, the power system is the power system of the extended-range vehicle. The control method shown includes: obtaining the type of road section where the vehicle is currently located based on the route information, and the route information is obtained by the vehicle navigation system according to the destination. Determine whether the type of road section is an elevated road section or a high-speed road section; if the type of road section is an elevated road section or a high-speed road section, judge whether the current speed of the vehicle is greater than the preset value; if the vehicle is driving on an elevated road section or a high-speed road section and the speed of the vehicle is greater than the preset value When the value is , the driving power of the vehicle is optimized to reduce the energy consumption of the vehicle. Based on the navigation technology, the invention obtains the route information of the navigation system, optimizes the driving power in a targeted manner, and improves the energy efficiency of the vehicle on the high-speed road section or the elevated road section.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a power system control method, system and vehicle of an extended-range vehicle. Background technique [0002] With the development of vehicle navigation and map information technology, the vehicle can obtain the route information in front of the vehicle through the navigation system during the driving process of the vehicle relying on the vehicle navigation system. After the vehicle controller obtains this information, it can plan and control according to the forward path information and vehicle status. Especially when the vehicle is driving on highways / expressways and other roads, it is less affected by external traffic factors, the vehicle operating conditions are relatively fixed, and the power demand is relatively stable, which is convenient for optimal control of the efficiency of the vehicle power system. When the origin and destination of the vehicle are determined, the ...
