Electric vehicle system driven by a combined electric motor and driving control method thereof

Abstract

The invention relates to an electric vehicle system driven by a combined electric motor and a driving control method thereof. The electric vehicle system driven by the combined electric motor comprises a vehicle controller, the combined electric motor, a combined electric motor driving controller, a power battery pack and a controller, wherein the combined electric motor driving controller is connected with the vehicle controller and used for controlling the combined electric motor to operate; the power battery pack is used for supplying power to the whole driving control system; the vehicle controller is also connected with an acceleration pedal angle sensor, a braking pedal angle sensor and a wheel speed sensor; and the combined electric motor driving controller is also connected with a combined electric motor voltage sensor, a combined electric motor current sensor, a combined electric motor rotation speed sensor, a combined electric motor torque sensor and a combined electric motor brake. According to the electric vehicle system driven by the combined electric motor, on the basis of the driving intention of the electric vehicle, one or more electric motors in the combined electric motor can be automatically selected as power to drive the electric vehicle according to a stable principle; therefore, the electric vehicle system driven by the combined electric motor has the advantages that the electric vehicle is energy-saving, the driving range of the electric vehicle is long, the dynamics performance of the electric vehicle is good, the service lives of the electric vehicle and parts are long and the application prospect of the electric vehicle system is important.

Description

Technical field [0001] The invention relates to an electric vehicle system based on a combined motor drive and a drive control method thereof. Background technique [0002] So far, many research and development and production activities have been carried out on electric vehicles at home and abroad, and good results have been achieved. However, because electric vehicle motors and vehicle controllers need to be further improved, there are still certain limitations.
