Abstract

A vehicle safety system that provides an improved line of sight for oncoming traffic as the vehicle is backed out of a parking space. A set of rear side looking cameras input video information to a display used by the vehicle driver. The cameras are positioned on the rear side portion of the vehicle and are directed generally to traffic coming from the rear left or right side of the vehicle. The camera is automatically activated when the transmission is placed in reverse. The camera video is input to a driver display that allows the driver to view oncoming traffic before the vehicle backs into the traffic lane. The system can also be used to monitor blind spots when a turn signal is activated prior to a lane change.

Claims

1. A safety system for backing a vehicle out of a parking space, comprising:

a side facing motion detection device mounted substantially at or near the rear end of a vehicle, the motion detection device positioned such that when the rear end of the vehicle is backing into a traffic lane, it detects other vehicles approaching the vehicle substantially perpendicular to the longitudinal length of the vehicle on either side of the vehicle when the motion detection device has a line of sight to the other vehicle; and

the motion detection device further having means to activate an alarm when another vehicle is detected approaching the vehicle from the side;

whereby the vehicle driver is automatically warned about other vehicles approaching from the sides when the vehicle is backing out a parking place such that a driver can avoid collisions with other vehicles when backing out of a parking place by detecting side impact traffic not visible by direct observation by the driver.

2. A system, as in claim 1, further comprising:

means to detect when the vehicle is placed in reverse gear and automatically activate the motion detection device when the vehicle is in reverse gear.

3. A system, as in claim 2, wherein:

the alarm is an audible alarm.

4. A system, as in claim 2, wherein:

the alarm is a lamp.

5. A system, as in claim 4, wherein:

the alarm is a lamp located in the vehicle and within a driver'"'"'s view.

6. A system, as in claim 4, wherein:

the alarm is a lamp located on the rear view mirror of the vehicle.

7. A system, as in claim 4, wherein:

the alarm is a lamp located on a side view mirror of the vehicle.

8. A system, as in claim 4, wherein:

the alarm is a lamp located on the left side view mirror of the vehicle and a second lamp located on the right side view mirror of the vehicle.

9. A system, as in claim 1, wherein:

the motion detection device uses radar, sonar, or infrared to detect motion of an oncoming object approaching from the side of the vehicle.

10. A system, as in claim 1, wherein:

the motion detection device is mounted on the rear end of the vehicle, and further having first and second motion detectors positioned such that, when the rear end of the vehicle is backing out of a parking space into a traffic lane, the first motion detector is positioned such that it detects objects in motion approaching the left side of the car and the second motion detector is positioned such that it detects objects in motion approaching the right side of the vehicle.

11. A system, as in claim 10, further comprising:

means to detect when the vehicle is placed in reverse gear and automatically activate the motion detection device when the vehicle is in reverse gear.

12. A system, as in claim 11, wherein:

the motion detection device uses radar, sonar, or infrared to detect motion of an oncoming object approaching from the sides of the vehicle.

13. A system, as in claim 10, wherein:

the motion detection device uses radar, sonar, or infrared to detect motion of an oncoming object approaching from the sides of the vehicle.

15. A method, as in claim 1, including the additional step of:

automatically activating the motion detection device when the vehicle is placed in reverse gear.

16. A method, as in claim 15, including the additional step of:

using radar, sonar, or infrared motion detection devices to detect motion of an oncoming object approaching from the side of the vehicle.

17. A method, as in claim 16, including the additional step of:

using an audible alarm to alert the driver when an object is detected approaching from the sides.

18. A method, as in claim 16, wherein:

using a lamp to alert the driver when an object is detected approaching from the sides.

14. A method of warning a driver when oncoming traffic is approaching a vehicle from the side when the vehicle is backing out of a parking space, including the steps of:

monitoring moving objects approaching from the side of the vehicle by positioning a motion detection device substantially at or near the rear end of a vehicle such that when the rear end of the vehicle is backing into a traffic lane, the motion detection device detects an oncoming moving object approaching the vehicle in a direct collision course toward the side of the vehicle; and

activating an alarm when a moving object is detected approaching the vehicle from the sides;

whereby the vehicle driver is automatically warned about other objects approaching from the side when the vehicle is backing out a parking place.

19. A method, as in claim 14, including the additional step of:

mounting side facing first and second motion detectors on the rear end of the vehicle such that when the vehicle is backing out of a parking space into a traffic lane, the first motion detector detects objects in motion approaching the left side of the car and the second motion detector detects objects in motion approaching the right side of the vehicle.

20. A method, as in claim 19, including the additional step of:

using radar, sonar, or infrared motion detection devices to detect motion of an oncoming object approaching from the sides of the vehicle.
