Abstract

A blind spot detection system comprises an alarm, capable of generating an alarm signal; a plurality of sensors, each for emitting a radio signal and receiving a reflecting signal of the emitted radio signal, to detect whether an object exists within a specific range and generate a detection result accordingly; and a control module, for receiving at least one vehicle information from the OBD system and controlling the alarm to generate the alarm signal according to the at least one vehicle information and a plurality of detection results generated by the plurality of sensors.

Claims

1. A blind spot detection system for a vehicle comprising an On-Board Diagnostics (OBD) system, the blind spot detection system comprising:

an alarm, capable of generating an alarm signal;

a plurality of sensors, each for emitting a radio signal and receiving a reflecting signal of the emitted radio signal, to detect whether an object exists within a specific range and generate a detection result accordingly; and

a control module, for receiving at least one vehicle information from the OBD system and controlling the alarm to generate the alarm signal according to the at least one vehicle information and a plurality of detection results generated by the plurality of sensors.

2. The blind spot detection system of claim 1, further comprising a transmission line, connecting the OBD system and the control module, for transmitting the at least one vehicle information.

3. The blind spot detection system of claim 2, wherein a connecting interface of the transmission line conforms to a standard interface of OBD II.

4. The blind spot detection system of claim 2, further comprising a plurality of signal transceivers, disposed between the transmission line and the control module, for converting data between the transmission line and the control module.

5. The blind spot detection system of claim 4, wherein one of the plurality of signal transceivers is capable of transmitting and receiving signals conforming to a communication standard of international organization for standardization 9143-2 or keyword protocol 2000.

6. The blind spot detection system of claim 4, wherein one of the plurality of signal transceivers is capable of transmitting and receiving signals conforming to a communication standard of society of automotive engineers J1850, pulse width modulation (PWM), or variable pulse width(VPW).

7. The blind spot detection system of claim 4, wherein one of the plurality of signal transceivers is capable of transmitting and receiving signals conforming to a communication standard of international organization for standardization 15756 or control area network.
