[0028] Embodiment:
[0029] As Figures 1 - 4As shown in the figure, the utility model provides an automotive body controller debugging bench system, which includes a high-level test circuit, a low-level test circuit, an analog signal test circuit, a bus signal test circuit, a high-side output signal test circuit and a low-side output test circuit. Each test circuit is connected to the automotive body controller through wires, so that various function tests of the body controller can be carried out. Both ends of the high-level key switch of the high-level test circuit are respectively connected to the high-level test line and the power supply (12V power supply). The high-level key switch can be a self-locking switch or a reset switch. When the high-level key switch is pressed, a high level is input to the body controller to simulate a high-valid input signal in the real vehicle environment. Both ends of the low-level key switch of the low-level test circuit are respectively connected to the low-level test line and the ground. The low-level key switch can also be a self-locking switch or a reset switch. When the low-level key switch is pressed, a low level is input to the body controller to simulate a low-valid input signal in the real vehicle environment. The analog signal test circuit includes two parallel analog signal key switches. One end of the two analog signal key switches is grounded, and the other end is connected to different resistors and then connected to the analog signal test line. In this embodiment, the resistance values of the resistors can be 1.2K and 0K. The bus signal test circuit is connected to the CAN bus line and the LIN bus line for testing the CAN bus and the LIN bus. The CAN bus is the most widely used automotive bus, mostly twisted pairs, so these two lines are also divided into a high-level data transmission line and a low-level data transmission line, namely CAN_H (CAN_High) and CAN_L (CAN_Low); the LIN bus provides a cost-effective and reliable low-speed network to replace the low-speed CAN bus system with lower cost. The high-side output signal test circuit is connected to the high-side LED lamp and the high-side current-limiting resistor (the resistance value is preferably 1K) and then grounded. The high-side LED lamp is turned on when a high-side signal is input; the low-side output signal test circuit is connected to the low-side LED lamp and the low-side current-limiting resistor (the resistance value is preferably 1K) and then connected to the power supply. The low-side LED lamp is turned on when a low-side signal is input. The automotive body controller debugging bench system provided by the utility model is convenient for carrying out various types of debugging of the body controller through the high-level test circuit, the low-level test circuit, the analog signal test circuit, the bus signal test circuit, the high-side output signal test circuit and the low-side output test circuit. It is simple to build, easy to operate, can accurately and quickly debug all functions of the body controller under development, has high test efficiency, and also has the advantage of low cost, and can better adapt to the industrial development of new energy vehicles.
[0030] As an optional implementation, such as Figure 4As shown, the debugging bench system further includes an antenna test circuit, which is connected to the antenna under test through an external banana socket.
