## Abstract

A vehicle safeguard device includes a setting unit, which is operative to set a vehicle that is in a parked state in a safeguard state; a detection unit, which is electrically connected to the setting unit to detect a horizon state and a signal interrupted state of the vehicle when the vehicle is in the safeguard state; a sensing unit, which receives the horizon state and the signal interrupted state of the vehicle detected by the detection unit; and a signal processing and control unit, which is electrically connected to the sensing unit to receive an abnormality signal of the horizon state and the signal interrupted state of vehicle sensed by the sensing unit and convert the abnormality signal into an alarm signal and transmit the alarm signal to an external management center.

## Claims

### Claim 1

A vehicle safeguard device, comprising:
a setting unit, which is operative to set a vehicle that is in a parked state in a safeguard state;
a detection unit, which is electrically connected to the setting unit to detect a horizon state and a signal interrupted state of the vehicle when the vehicle is in the safeguard state;
a sensing unit, which receives the horizon state and the signal interrupted state of the vehicle detected by the detection unit; and
a signal processing and control unit, which is electrically connected to the sensing unit to receive an abnormality signal of the horizon state and the signal interrupted state of vehicle sensed by the sensing unit and convert the abnormality signal into an alarm signal and transmit the alarm signal to an external management center.

### Claim 2 (depends on 1)

The vehicle safeguard device as claimed in claim 1, wherein the setting unit, when setting the vehicle in the safeguard state, transmits an audio voice message to the external management center.

### Claim 3 (depends on 1)

The vehicle safeguard device as claimed in claim 1, wherein the detection unit comprises a horizon detector, which detects if the vehicle is in a horizontal condition when the vehicle is set in the safeguard state.

### Claim 4 (depends on 1)

The vehicle safeguard device as claimed in claim 1, wherein the detection unit comprises a signal interruption device, which detects if a safeguard signal of the vehicle is interrupted when the vehicle is set in the safeguard state.

### Claim 5 (depends on 1)

The vehicle safeguard device as claimed in claim 1, wherein the vehicle, when in the safeguard state, is also in a fuel passage shutoff state.

### Claim 6 (depends on 1)

The vehicle safeguard device as claimed in claim 1, wherein the vehicle, when in the safeguard state, is also in a fuel passage non-shutoff state.
