Alarm system for electric leveling of vehicle and vehicle

The invention discloses an alarm system for electric leveling of a vehicle and the vehicle applying the alarm system. The alarm system comprises an alarm buzzer and a magnetic latching relay, whereinone end of the alarm buzzer is connected to an automobile ignition switch, and the other end of the alarm buzzer is connected with a memory pin of the magnetic latching relay; an action pin of the magnetic latching relay is connected with the output end of a position sensor; the position sensor is installed in the electric leveling system and used for detecting whether the supporting legs are retracted in place or not; and a memory pin of the magnetic latching relay is connected between the alarm buzzer and the power ground. The alarm system and the electric leveling system are mutually independent in power supply, and when the electric leveling system is powered off, the supporting leg withdrawing in-place state detection signal is detected to be consistent with the power supply of the electric leveling system. 本
