Real-time simulation system and method for series-parallel hybrid driven vehicle based on dSPACE

Abstract

The invention discloses a real-time simulation system and method for series-parallel hybrid driven vehicle based on dSPACE. The simulation system comprises a vehicle controller, a dSPACE hardware platform, a computer system, an upper-layer information management system and a communication module; the vehicle controller is used for controlling the motion state, motion direction or motion time of the series-parallel hybrid driven vehicle; the dSPACE hardware platform is used for receiving and transmitting motion state, motion direction or motion time data of the series-parallel hybrid driven vehicle; the computer system is used for calculating, displaying, processing or transmitting running data of the series-parallel hybrid driven vehicle; the upper-layer information management system is used for receiving or monitoring the computer system to calculate and process the running data of the series-parallel hybrid driven vehicle; and the communication module is used for transmitting the data sent by the computer system to the upper-layer information management system. According to the invention, the real state of the series-parallel hybrid driven vehicle can be simulated, and data transmission and sharing are realized.

Description

technical field [0001] The present invention relates to the technical field of a hybrid power system, and more particularly relates to a hardware-in-the-loop testing system and method for a hybrid power system. Background technique [0002] The vehicle controller is the core of the vehicle control system, which directly communicates with the driver. The operations done by the driver driving the car are directly sent to the vehicle controller. What the driver can control is the key switch, accelerator pedal, brake pedal, and gearbox gear, and the vehicle controller can control the key switch, accelerator pedal, brake pedal, The node data of the control system, vehicle sensor data, vehicle operating status data, etc. are collected and processed, and the processing results are released through the CAN bus in the form of control messages, and the central processing units of other control systems perform corresponding operations according to the information received from the CAN...
