Benefits of technology

The technical effect of this patented technology allows for control over both the speed at which vehicles are driven with an electric machine (motor) while maintaining their ability to respond quickly when needed or reducing power consumption during certain periods of operation. This improves fuel economy efficiency without sacrificing performance.

Problems solved by technology

This patented technology solves this problem where an electronic device called a car's computer sends instructions that help it adjust its output based on how well they are doing with their battery pack during different modes like gasoline-powered cars without being affected negatively from other factors such as fuel economy.

Abstract

The invention provides a method and a device for controlling the power assisting function of a vehicle. The method comprises the steps that a current working mode fed back by a vehicle control unit is obtained; the working modes comprise a pure electric mode, a traditional mode and a hybrid mode; if the obtained working mode is a traditional mode or a hybrid mode, a dynamic power assisting function is executed, and the execution of the dynamic power assisting function comprises the steps that a motor dynamic power assisting torque demand is sent to a motor, and an actual motor dynamic power assisting torque returned by the motor is received; and the power performance of the engine is compensated according to the actual dynamic power-assisted torque of the motor. According to the dynamic torque compensation method, device, the whole vehicle controller controls the motor with the fast response to conduct dynamic torque compensation, the whole vehicle requirement can be met in a short time, the whole vehicle acceleration performance is improved, and the driving feeling is improved.
