Four-wheel drive pure electric vehicle hardware-in-loop simulation experimental system

Abstract

The invention relates to a four-wheel drive pure electric vehicle hardware-in-the-loop simulation experimental system. The system comprises a drive motor and controller subsystem, an electric dynamometer and controller subsystem, torque and rotational speed sensors, a vehicle dynamic model real-time simulation subsystem and a signal detection and analysis subsystem. The system achieves pure electric vehicle four-wheel independent drive via the motor and controller subsystem, and achieves simulation of vehicle travel load via the electric dynamometer and controller subsystem. Vehicle dynamic response is achieved by operating a real-time simulation model through a real-time controller, and signal input, output and conditioning of a vehicle control unit are achieved by the aid of an FPGA (field programmable gate array). The system is capable of performing hardware-in-the-loop simulation for four-wheel drive pure electric vehicles to achieve rapid development and product testing of a vehicle drive system, and has the advantages of energy saving, safety, rapidness and low cost.

Description

technical field [0001] The invention relates to a simulation system, in particular to a hardware-in-the-loop simulation experiment system for a four-wheel drive pure electric vehicle. Background technique [0002] Energy conservation, environmental protection and safety have become the themes of modern automobile development. In order to solve the energy crisis and environmental pollution caused by the increase in automobile ownership, the research and development of new energy vehicles has become one of the focuses of research in various countries. A pure electric vehicle is a vehicle that uses electric energy to drive a motor as its power system. Because of its zero emissions, simple structure, high efficiency, and relatively mature technology, it has become an important development form of new energy vehicles. If the pure electric vehicle adopts the four-wheel drive form, the mechanical transmission device required by the traditional vehicle can be omitted, the drive syst...
