Car door opening pre-detection system
First Claim
1. A car door opening pre-detection system for a car, the car door opening pre-detection system comprising:
- a first detecting module installed in an interior portion of the car, wherein the first detecting module issues a motion detecting signal according to a result of detecting a motion of a palm;
a second detecting module installed on an exterior portion of the car, wherein when the car is stopped, the second detecting module is enabled to selectively provide a first detection range or a second detection range; and
a control module electrically connected with the first detecting module and the second detecting module, wherein the control unit receives the motion detecting signal and judges whether a car door of the car is about to be opened according to the motion detecting signal,wherein when the car is stopped and the control module judges that the car door is about to be opened, the first detection range of the second detecting module is switched to the second detection range under control of the control module, and the second detecting module provides the second detection range to detect whether a moving object behind the car is close to the car within the second detection area,wherein the second detection range has a larger detecting angle than the first detection range and a smaller detecting distance than the first detection range.

Abstract
A car door opening pre-detection system for a car includes a first detecting module, a second detecting module and a control module. The first detecting module is installed within the car. The first detecting module issues a motion detecting signal according to a result of detecting a motion of a palm. The second detecting module is installed outside the car. When the car is stopped, the second detecting module is enabled to selectively provide a first detection range or a second detection range. The control unit judges whether a car door of the car is about to be opened according to the motion detecting signal. When the car is stopped and the control module judges that the car door is about to be opened, the second detecting module provides the second detection range to detect whether there is a moving object behind the car.
