20090207012 | Turn signal appropritate use reminder system - 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. | 08-20-2009 |
20090237230 | Lane change turn signal appropritate use reminder system - 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. | 09-24-2009 |
20130268162 | Turn Signal Controlled Regenerative Braking And Decelerative Loading - A vehicle executing a turn will most likely be slowed down before the turn and when a driver activates a turn signal to indicate the turn, a vehicle internal controller uses this information to engage regenerative braking for energy recapture while slowing down the vehicle for the pending turn. Since the turn signal is usually activated very early in the turn event, and turns are an ongoing, frequent part of driving, a greater overall vehicle efficiency can be realized without special effort from the driver. Implementation is relatively simple for the manufacturer and adds no cost since the controllers and sensors are already installed on nearly all roadworthy vehicles. Fuel mileage and vehicle driving ranges are improved on a large scale and brake system wear is reduced. | 10-10-2013 |
