Abstract The invention discloses an automatic test system of a vehicle-mounted product, which comprises a main control chip U24, a voltage input circuit electrically connected with the main control chip U24, a 5V voltage stabilizing circuit, a 3.3 V voltage stabilizing circuit, a battery detection circuit, a crystal oscillator circuit, a reset circuit, a filter circuit, a transceiver circuit, a burning circuit and an anti-reverse connection circuit, and is characterized in that the battery detection circuit comprises a resistor R109 connected to a 24V input end; one end of the resistor R109 is connected with a resistor R108, and one end of the resistor R108 is connected to a pin 10 of the main control chip U24. The vehicle-mounted product aging test system automatically completes the test of the vehicle-mounted product, only when the test goes wrong, manual intervention is performed, the operation of the vehicle and the use condition of the product on the vehicle are simulated to carry out aging test, the test frequen
