Abstract

A blind spot detection system for a vehicle includes a vehicle information detecting module for obtaining at least one vehicle information of the vehicle corresponding to an external environment, an alarm for generating an alarm signal, a plurality of sensors each for emitting a radio signal and receiving a reflecting signal of the transmitted radio signal to detect whether an object exists within a specific range and generate a detection result accordingly, and a control module for 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:

a vehicle information detecting module, for obtaining at least one vehicle information of the vehicle corresponding to an external environment;

an alarm, for generating an alarm signal;

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

a control module, for 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, wherein the vehicle information detecting module comprises a Global Positioning System receiver for calculating a velocity of the vehicle as the at least one vehicle information.

3. The blind spot detection system of claim 1, wherein the vehicle information detecting module comprises an accelerometer for calculating an acceleration value of the vehicle as the at least one vehicle information.

4. The blind spot detection system of claim 1, wherein the vehicle information detecting module comprises a gyroscope for calculating an angle of the vehicle corresponding to a plumbline as the at least one vehicle information.

5. The blind spot detection system of claim 1, wherein the control module is further utilized for controlling operations of the plurality of sensors according to the at least one vehicle information.

6. The blind spot detection system of claim 1, wherein the control module further sends the at least one vehicle information to the plurality of sensors, and each of the plurality of sensors is further utilized for controlling generation of the detection result according to the at least one vehicle information.

7. The blind spot detection system of claim 1, further comprising a plurality of signal transceivers between the plurality of sensors and the control module, for transforming data between the plurality of sensors and the control module.
