The embodiment of the invention discloses an automobile sound wave simulation method and device, a storage medium and a vehicle-mounted diagnosis system. The method comprises the following steps: receiving a temperature feedback signal sent by a micro control unit (MCU), and determining a temperature change condition according to the temperature feedback signal; receiving a rotating speed feedback signal sent by the engine, and determining a rotating speed change condition according to the rotating speed feedback signal; receiving an oxygen concentration feedback signal sent by the oxygen sensor, and determining an oxygen concentration change condition according to the oxygen concentration feedback signal; receiving a fuel quantity feedback signal sent by the fuel system, and determining a fuel quantity change condition according to the fuel quantity feedback signal; and determining a sound wave change mode according to the temperature change condition, the rotating speed change condition, the oxygen concentration change condition and the oil quantity change condition, and controlling the state of the exhaust valve according to the sound wave change mode so as to simulate the automobile sound wave. In this way, the state of the exhaust valve is controlled by combining the change conditions of various automobile data, and the automobile sound better conforming to the real driving condition of the automobile can be simulated.
