Abstract

The invention discloses a power system control unit in-the-loop simulation test system. The system comprises a driver model unit, a simulation VCU (vehicle control unit) unit, a simulation MCU (motor control unit) unit, a simulation BMS (battery management system) unit, a VCU test interface, an MCU test interface and a BMS test interface; one end of the simulation VCU unit is connected with the driver model unit, and the other end of the simulation VCU unit is connected with the VCU test interface; one end of the simulation MCU unit is connected with the driver model unit, and the other end of the simulation MCU unit is connected with the MCU test interface; and one end of the simulation BMS unit is connected with the driver model unit, and the other end of the simulation BMS unit is connected with the BMS test interface. Pathways between the driver model unit and the simulation CU (control unit) units are switched out, and pathways between the test interfaces and automobile CU (control unit) units are switched on, so a test of any combination between the simulation VCU unit, the simulation MCU unit and the simulation BMS unit of a power system control unit is achieved.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a power system controller-in-the-loop simulation test system. Background technique [0002] With the increasing shortage of petroleum energy and the deterioration of the atmospheric environment, electric vehicles are favored by people because of their high efficiency and zero pollution advantages. Electric vehicles have three core controllers, namely the vehicle controller (Vehicle Control Unit, VCU) unit, the motor controller (Motor Control Unit, MCU) unit and the battery management (Battery Management System, BMS) unit. As the core component of the electric vehicle control system, the VCU unit needs to be greatly enhanced in function, and the control system itself is becoming more and more complicated. It plays a vital role in ensuring the safe and reliable driving of electric vehicles. In addition, the MCU unit controls the motor to work according to the set direction, speed,...
