Abstract

Disclosed is a method to use existing arts of radar to produce a system that detects the possibility of a collision with an open door when a vehicle is stopped. When a potential collision is detected, the system invokes a restrain mechanism to either block the door or inform people in a vehicle that an obstacle is about to come within the door's range.

System to Prevent Car Door Collision with Cyclists and Pedestrians

When a motorist opens the door of a vehicle while a cyclist is passing by , it can result in serious injuries to the cyclist and potentially damage the door. Currently, the only methods to prevent this problem are vigilance and dedicated bike lanes .

The novel solution is a method to pair existing art to produce a system that detects cyclists when the car is stopped and invokes a restrain mechanism to either block the door or inform people in a vehicle that an obstacles is about to come within the door's range.

The system uses existing arts of radar, both short range and long range, lidar, or any other obstacle detection system. Those systems remain active to continually detect potential moving obstacles, as long as passengers are within the vehicle. When the system predicts that an obstacle is going to pass within the range of the door in a configurable time range (e.g., 15 seconds), it activates various security measures to prevent the collision. The types of collisions to detect include:

• Passing pedestrian • Passing cyclist • Passing vehicles (e.g., car, trucks, motorcycle, etc.)

• Proximity to other static obstacles (e.g., curb, tree, other parked vehicles, etc.)

The safety triggers include any combination of the following devices:


• An audio warning about the possible collision


• A visual signal such as a light to indicate how safe it is to open the door
