[0022] like Figure 1 As shown, an embodiment of this application provides a simulated cockpit device for automotive cockpit acceptance testing. The simulated cockpit device includes a test bench, a temperature sensor, and a sliding rheostat. The test bench simulates the main body of the automotive cockpit to be tested. The temperature sensor is mounted on the test bench and contains a thermistor. The sliding rheostat is mounted on the test bench and connected in series with the thermistor. In this embodiment, a simple test bench is built to simulate the structure of the main body of the automotive cockpit. Necessary components such as the entertainment system, comfort system, and lighting system of the vehicle to be tested can be mounted on the test bench. In some embodiments, powertrain-related components (engine, transmission, etc.) are simulated using software, further reducing costs and enabling the realization of all functions under static conditions of the vehicle cockpit. Components requiring acceptance testing (such as controllers) can be quickly installed and removed on the test bench, facilitating component replacement during new model upgrades. Temperature sensors can simulate the driving conditions of a real vehicle and the temperature of the external application environment. By changing the resistance value of the sliding rheostat, the total resistance value of the temperature-sensitive resistor and the sliding rheostat connected in series is changed, thereby affecting the reading of the temperature sensor and enabling convenient adjustment of the temperature sensed by the temperature sensor.

[0023] The simulated cockpit device for automotive cockpit acceptance testing provided in the embodiments of this application simulates the automotive cockpit using a test bench, eliminating the need for prototype manufacturing of a real vehicle, thus reducing costs.

In this embodiment, by setting up the noise system 1, the noise of a real vehicle can be simulated after the vehicle is started, and the noise level increases with speed, making it closer to the real vehicle during voice control function testing. The noise system 1 can be implemented by emitting sound through a speaker.

[0025] In some embodiments, the simulated cockpit device further includes a body control module (BCM) and a first pin connector 2. The body control module is mounted on a test bench; the first pin connector 2 is mounted on the test bench, and the pins of the body control module are connected to the sockets in the first pin connector 2. In this embodiment, by setting the first pin connector 2, the body control module can be easily debugged and its wiring modified without having to disassemble and reassemble the body control module each time it is debugged or modified.

[0026] In some embodiments, the bottom of the test bench is provided with multiple casters 3. In this embodiment, by providing casters 3, the movement of the test bench can be facilitated, making testing more convenient. Preferably, the casters 3 can have a locking function to prevent accidental movement of the test bench.

[0028] In some embodiments, the simulated cockpit device further includes a second pin connector 4, which is mounted on a test bench. The pins of the vehicle's main unit controller are connected to the sockets in the second pin connector 4. In this embodiment, by providing the second pin connector 4, the controller of the vehicle's main unit can be easily debugged and its wiring modified without having to disassemble and reassemble the main unit each time it is debugged or modified.

[0029] In some embodiments, the simulated cockpit device further includes an ultrasonic radar 5, which is mounted on a test bench. A first mounting beam 6 is provided at the front end of the test bench, and the first mounting beam 6 is slidably mounted at the front end of the test bench to change its height. The ultrasonic radar 5 is slidably mounted on the first mounting beam 6, and the ultrasonic waves can slide along the extension direction of the mounting beam. In this embodiment, this arrangement facilitates the verification of the detection angle of the ultrasonic radar 5.

[0031] In some embodiments, the simulated cockpit device further includes a dashcam camera 8, which is slidably mounted on a second mounting beam 9 in front of the driver's seat on the test bench. The dashcam camera is capable of sliding along the extension direction of the second mounting beam 9. In this embodiment, this arrangement facilitates the verification of the dashcam camera's detection range.

[0032] Combination Figure 2 In some embodiments, the simulated cockpit device further includes a test bench, which is electrically and communicatively connected to the test rig. The test bench is equipped with a power distribution box, which is electrically connected to the test rig and supplies power to both. The test bench also includes a touchscreen display, which is communicatively connected to the test rig. In this embodiment, the test bench may be equipped with a 220V power supply, fuse box, power distribution box, industrial computer, display, lighting, Ethernet interface, CAN interface, LIN interface, 12VDC interface, OBD interface, etc. The environmental simulation model runs in the CANoe project of the engineering machine, used to send and receive relevant signals and control the operation and function display of the test rig. Function control operations can be performed on both the physical buttons on the test rig and the virtual panel, and the two are linked, with the virtual panel matching the actual state of the test rig. For example, starting and stopping the test rig can be done in two ways, either through the physical buttons on the test rig or the touchscreen display on the test bench. There are two modes for simulating vehicle speed: dynamic and static. In static simulation, you can manually input a fixed speed to keep it constant. In dynamic simulation, the speed is calculated based on the state of the brake and accelerator pedals to determine whether the speed increases or decreases.
