AI Technical Summary

Technical Problem

In existing hybrid vehicles, the engine and motor are simply superimposed, resulting in low effective utilization of the motor, large space occupation, and poor power and economy.

Method used

A vehicle power system is provided, including an engine drive mechanism and a motor drive mechanism, which supports multiple driving modes and braking modes, and charges a power battery by driving the engine through the motor, thereby improving the effective utilization rate of the motor.

Benefits of technology

The integration of the engine and motor is achieved, which retains the energy-saving characteristics of electric vehicles, makes up for the disadvantage of insufficient driving range, and improves the effective utilization rate of the power motor and the power performance of the whole vehicle.

Abstract

The present application relates to a vehicle power system, a power control method, and a vehicle. The vehicle power system includes an engine drive mechanism and a motor drive mechanism. The engine drive mechanism includes a steering electric drive axle and a power battery connected thereto. The motor drive mechanism includes an engine, a clutch, and a gearbox. The steering electric drive axle includes a power motor connected to the engine. The vehicle power system has a first drive mode, a second drive mode, and a third drive mode. In the first drive mode, the motor drive mechanism and the engine drive mechanism are configured to jointly drive the entire vehicle. In the second drive mode, the motor drive mechanism is configured to independently drive the entire vehicle. In the third drive mode, the motor drive mechanism is configured to independently drive the entire vehicle, and the engine of the motor drive mechanism is configured to drive the power motor to charge the power battery. This vehicle power system can solve the problem of low effective utilization of the power motor in hybrid vehicles.
