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, independent from an electronic controller inside the vehicle, for obtaining at least one vehicle information of the vehicle corresponding to an external environment, wherein the at least one vehicle information comprises at least one of an acceleration value and degree of inclination corresponding to a plumb line;

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;

a control module, comprising;

a central processor, coupled to the vehicle information detecting module, the alarm, and the plurality of sensors; and

a storage device, storing a program code for instructing the central processor to control 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 and to send the at least one vehicle information to the plurality of sensors; and

a plurality of signal transceivers between the plurality of sensors and the control module, for amplifying or converting data between the plurality of sensors and the control module;

wherein the vehicle information detecting module is built in the blind spot detection system for secluding interference;

wherein the control module further sends the at least one vehicle information to the plurality of sensors according to the program code, and each of the plurality of sensors determines whether to operate according to the at least one vehicle information.

2. The blind spot detection system of claim 1, wherein the vehicle information detecting module further comprises a Global Positioning System receiver for calculating a velocity of the vehicle such that the at least one vehicle information further comprises the velocity.

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 plumb line as the at least one vehicle information.
