Problems solved by technology

However, due to the high price of dSPACE, in order to save costs, many domestic research institutions have given up using the dSPACE system and explored other methods to complete hardware-in-the-loop simulation
[0006] Due to the slow transmission speed of the existing CAN communication network, if there are many nodes on the single bus, the bus load rate is relatively high, resulting in serious data loss
Therefore, considering the problem of load rate, using a single-bus CAN communication network to complete the communication of information flow and energy flow cannot guarantee the real-time and accuracy of the simulation system

Abstract

The invention discloses a hardware-in-loop experimental system for an entire electric vehicle controller. The system comprises an entire controller to be tested, an analogue controller and a monitoring test bench. The entire controller to be tested, the analogue controller and the monitoring test bench can perform control information interaction and energy flow information interaction through an information flow controller area network (CAN) bus and an energy flow CAN bus. The accuracy of the entire controller can be accurately and quickly inspected, portability and expandability can be realized, and the prototype development of the entire controller can be realized; and the cost of a simulation system is lowered, problems about the real-time performance and accuracy when a single-bus CAN communication network is applied to the simulation system are solved, and the performance of the simulation system is improved. The system is simple in structure and easy to operate and implement, and different entire controllers can be tested in real time according to analogue modesl defined by a user.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a hardware-in-the-loop experiment system for a complete vehicle controller of an electric vehicle. Background technique [0002] An electric vehicle is a vehicle that uses electric energy to drive a motor as a power system. Due to its high environmental protection, it is more and more widely used in daily life. [0003] The vehicle controller is the core control component of the entire electric vehicle vehicle control system. It can control the vehicle according to the driver's instructions such as the position of the accelerator pedal, gear position, brake pedal force, air-conditioning switch, and state variables such as the SOC and temperature of the battery. Calculate the driving power, torque and other parameters required for operation, so as to coordinate the operation of various components and ensure the normal driving of the vehicle. In addition, energy recovery ...
