The invention relates to a power domain controller low-voltage load simulation system, which relates to the technical field of vehicle engineering, and comprises a human-computer interaction interface, a main control module, an analog signal circuit, a digital signal circuit, a PWM (Pulse Width Modulation) signal circuit, a first analog function group, a second analog function group, a third analog function group and a programmable power supply. According to the invention, parameter changes in a load simulation process can be displayed by setting the human-computer interaction interface, a command can be directly issued to the main control module, and the power domain controller to be detected can be detected by setting the main control module and connecting the analog signal circuit, the digital signal circuit and the PWM signal circuit. The power domain controller to be detected can output and collect analog signals, digital signals and PWM signals, when load simulation is carried out on the power domain controller to be detected, the signals are collected through the main control module, the same load simulation is carried out, the two load simulation processes are all displayed on a man-machine interaction interface, and the fault part is displayed more accurately.
Description
technical field [0001] The invention relates to the technical field of vehicle engineering, in particular to a low-voltage load simulation system of a power domain controller. Background technique [0002] The power domain controller reasonably controls the working state and power output of the motor according to the driver's requirements, vehicle status and other working conditions to meet the requirements of driving conditions, including acceleration and deceleration, constant speed, braking, and reverse conditions. Therefore, the power domain controller The controller is the key power distribution component of the new energy vehicle, and its power distribution capability needs to be detected, as well as whether the power domain controller is faulty. [0003] However, in the simulation equipment of the existing controller, the lack of the intervention of the accelerator pedal, key switch, gear signal, electronic handbrake, air conditioner and other components in the new en...
