Abstract

The invention provides an energy feedback control method and device for an electric vehicle and the vehicle. The method comprises the steps of in a vehicle navigation mode, obtaining a navigation route of the vehicle according to the current position of the vehicle and a preset target position, and segmenting the navigation route to obtain a plurality of road sections; according to the information of the current environment where the vehicle is located, the current vehicle running state and the current residual energy of the vehicle, calculating the travelable mileage; and when the travelable mileage is less than or equal to the current display mileage of the vehicle, when the vehicle travels to the current road section, selecting one brake feedback gear from a plurality of preset brake feedback gears according to the corresponding road condition of the vehicle so as to enable the vehicle to conduct energy feedback on the current road section according to the selected brake feedback gear. According to the displayed mileage target, the navigation route is segmented, the energy recovery state is automatically adjusted according to the road condition of each road section, energy is saved, and achievement of the mileage target is promoted.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an energy feedback control method, device and vehicle of an electric vehicle. Background technique [0002] As the world's environmental protection issues and energy crisis become more and more prominent, new energy electric vehicles with the characteristics of saving fuel energy, low exhaust emissions, less pollution, and low noise have become the goal pursued by people. At present, the development and popularization of electric vehicles are facing many challenges, especially the limitation of battery technology still makes driving range the main obstacle to the development of electric vehicles. The energy feedback technology can recover part of the energy during the sliding and braking stages of the vehicle, which can greatly improve the driving range of the vehicle and the utilization rate of the vehicle's energy. [0003] The existing energy feedback technology is based ...
