Abstract

A vehicle safety system to improve lane change turn signal use by creating a conditioned response in the driver of a motor vehicle such that turn signals are used more appropriately over time for changing lanes. This is achieved using existing lane departure warning components and comparing each lane change at lower speeds to the coinciding turn signal on/off status, and determining if turn signal usage was appropriate. If lane changes indicate repeated, neglectful turn signal usage, a reminder message is presented to the driver. The lane departure warning remains functional at higher speeds, but at lower speeds, the present invention provides a less abrupt, friendly reminder message to use turn signals for lane changes. Drivers who repeatedly neglect to use turn signals will over time increase usage and reminder messages will cease, thereby improving vehicle safety by increasing appropriate turn signal use while changing lanes.

Claims

1. A vehicle lane change turn signal monitoring and reminder system comprising:

a means of monitoring a vehicle position in a roadway lane;

a means of monitoring vehicle turn signal on or off status;

a means of comparing said vehicle position in a roadway lane and coinciding said vehicle turn signal on or off status to make a determination of an appropriate turn signal usage based upon a first predetermined criteria;

a means of determining if a second predetermined criteria is met based on at least one recent history said determination outcome of the first predetermined criteria;

wherein a reminder is initiated intermittently, based upon the outcome of said second predetermined criteria.

2. The vehicle lane change turn signal monitoring and reminder system of claim 1, wherein said reminder substantially forms the basis for a communication to a driver of the vehicle.

3. The vehicle lane change turn signal monitoring and reminder system of claim 2, wherein said communication can be manually disabled.

4. The vehicle lane change turn signal monitoring and reminder system of claim 2, wherein said communication comprises at least one format selected from the group consisting of an audible format, and a tactile format.

5. The vehicle lane change turn signal monitoring and reminder system of claim 2 wherein said communication comprises a visual format.

6. The vehicle lane change turn signal monitoring and reminder system of claim 5, wherein said visual format is a message-changeable display.

7. The vehicle lane change turn signal monitoring and reminder system of claim 1, wherein said first predetermined criteria comprises at least one input format comprising from a vehicle mounted forward facing image detection device.

8. A method of conveying a lane change turn signal reminder message to a driver of a vehicle comprising:

configuring a means of monitoring a vehicle position in a roadway lane;

configuring a means of monitoring vehicle turn signal on or off status;

configuring a means of using a first predetermined criteria to determine appropriate use of a turn signal based upon said vehicle position in a roadway lane and coinciding said vehicle turn signal on or off status;

configuring a means of determining if a second predetermined criteria is met based on at least one recent history said determination outcome of the first predetermined criteria;

configuring a means of conveying a reminder message intermittently to said driver relating to turn signal usage based upon the outcome of said second predetermined criteria, whereby said message substantially conveys a recommendation for future turn signal usage.

9. The method of claim 8, whereby said driver'"'"'s future behavior is conditioned to use turn signals more appropriately for lane changes.

10. The method of claim 8, whereby said message can be manually disabled.
