A safety system of a vehicle is provided to normally operate the safety system when electricity is cut off from a battery during an alarm mode of the safety system and to call an owner of the vehicle out. A safety system of a vehicle comprises a vehicle battery(11), a buzzer(12), a safety controller(13), sensors(141,142), sensor switches(144,145), a computer(15) in the vehicle, a wireless communication module(16), and a remote signal receiver(17). The computer in the vehicle has a backup power unit, a switch(152), a detecting circuit(153), and a memory(155). The vehicle battery is electrically connected with the buzzer, the safety controller, the computer in the vehicle, and the wireless communication module to provide operating voltage to each element so as to be normally operated. The buzzer, the computer in the vehicle, the sensors, and the sensor switches are electrically connected with the safety controller. The safety controller and the computer in the vehicle are connected through a data line like RS232. |
