Abstract

A vehicle scratch detection system includes a scratch detection element, disposed on a vehicle body and capable of detecting a scratch of the vehicle body, a control unit, configured to be capable of analyzing and processing detection information of the scratch detection element and determining information related to scratch, and an alarm device. The control unit is capable of triggering the alarm device to send an alarm signal according to a result of the analyzing and processing.

First claim

What is claimed is:

1. A vehicle scratch detection system, comprising:
a scratch detection film disposed on a vehicle body and capable of detecting a scratch of the vehicle body;
a control unit configured to be capable of analyzing and processing detection information of the scratch detection film and determining information related to a scratch; and
an alarm device, wherein
the control unit is capable of triggering the alarm device to send an alarm signal according to a result of the analyzing and processing of the detection information.

2. The vehicle scratch detection system according to claim 1 , wherein
the information related to the scratch comprises: whether a scratch occurs, a scratch position, a scratch strength and/or a scratch area.

3. The vehicle scratch detection system according to claim 1 , further comprising:
a camera, wherein
the control unit is configured to be capable of triggering the camera according to said information related to the scratch so as to record a corresponding real-time scratch scene.

4. The vehicle scratch detection system according to claim 3 , further comprising
a storage device, wherein
the information related to the scratch, a result of said analyzing and processing and/or the recorded real-time scratch scene, is stored in the storage device.

5. The vehicle scratch detection system according to claim 1 , wherein
the scratch detection film is applied to a lower portion of four sides of the vehicle body.

6. The vehicle scratch detection system according to claim 1 , wherein
the scratch detection film is applied to front and rear fenders of the vehicle, exterior trim panels of vehicle doors, a side of a trunk lid and/or exterior trim panels of front and rear bumpers.

7. The vehicle scratch detection system according to claim 1 , wherein
the scratch detection film is a pressure-sensitive film or a piezoelectric film, such that when the pressure-sensitive film or piezoelectric film, which is energized, is subjected to an external force so as to be deformed, a current thereof varies, and a current variation signal is transmitted to the control unit.

8. The vehicle scratch detection system according to claim 1 , wherein
the scratch detection film is applied to the vehicle body when the vehicle body is manufactured or is installed or modified afterwards.

9. The vehicle scratch detection system according to claim 1 , wherein
the alarm signal is transferred to a driver or passenger within an automobile through a human-machine interface or is transmitted to a cloud server or a remotely related person in a wireless transmission manner.

10. The vehicle scratch detection system according to claim 9 , wherein
the human-machine interface is a sound, light, or image interface, and
the wireless transmission is carried out via a mobile network, WiFi, or Bluetooth.

11. The vehicle scratch detection system according to claim 2 , wherein
the alarm signal is transferred to a driver or passenger within an automobile through a human-machine interface or is transmitted to a cloud server or a remotely related person in a wireless transmission manner.

12. The vehicle scratch detection system according to claim 3 , wherein
the alarm signal is transferred to a driver or passenger within an automobile through a human-machine interface or is transmitted to a cloud server or a remotely related person in a wireless transmission manner.

13. A vehicle comprising a vehicle scratch detection system according to claim 1 .
