CAR DOOR OPENING DETECTION SYSTEM AND METHOD THEREOF

摘要

A car door opening detection system and a method thereof are provided. The car door opening detection system includes a transmitter, a sensor, and a control unit. The transmitter is electrically connected to a car circuit of a car. The car circuit is electrically connected to a power source of the car. When a car door of the car is opened, the car circuit is turned on to receive a power from the power source, and the transmitter is enabled to transmit an infrared (IR) signal. The sensor is disposed within the car and faces the transmitter. The sensor receives the IR signal and transmits a corresponding digital signal in response to the IR signal. The control unit is coupled to the sensor and receives the corresponding digital signal. When the corresponding digital signal is classified as a predetermined pattern, the control unit identifies that the car door is opened.
