ABSTRACT:
A vehicle safety system to improve 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. This is achieved using existing vehicle components to monitor a running recent history of executed turns, comparing each turn to the coinciding turn signal on/off status, and determining if turn signal usage was appropriate. If the recent history is indicative of neglectful turn signal usage, a reminder message is presented to the driver. If a driver is appropriately using turn signals nearly all of the time, then no reminder is ever presented, thus the system will never be considered a nuisance and is transparent to most drivers. 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.
