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.
