Turn Signal Usage Becomes Automatic with Smart Intelliturn System, Improving Vehicle Safety

Share Article

RLP engineering has developed an enhancement to its existing Intelliturn smart turn signal system whereby turn signal usage becomes automatic for the first time ever. This patent pending system ensures that turn signals are appropriately and accurately displayed for both turn-on and shut-off. It is a low cost system that replaces the original and still-common 70 year old mechanical technology, thereby improving vehicle safety by serving to prevent accidents.

RLP Engineering today announced an important enhancement to its existing Intelliturn smart turn signal system that now includes an automatic turn-on function. While the original Intelliturn provides computer controlled turn signal shut-off that is accurate and appropriate for all conditions, the new patent pending enhancement is a user friendly system where turn signal use becomes automatic with driver-in-the-loop technology. Turn signals become appropriately used, improving vehicle safety and reducing the risk of a collision.

"Turn signal control has not improved in almost 70 years and now Intelliturn assists drivers of all skill levels with computer control for both smart shut-off and turn on" states Richard Ponziani, President of RLP Engineering. "It all comes down to better driver-to-driver communication. The intent is an accurate turn signal every time. The goal is collision avoidance. The bottom line outcome is improved vehicle safety" he added.

Proper usage of turn signals has always been important for the prevention of accidents. Additionally, the use of turn signals is not only courteous to other drivers, but it is also the law. Since turn signal use is solely left to the discretion of the driver, there are drivers who neglect to use turn signals when they should and thus put themselves and others at risk. With this new Intelliturn enhancement, drivers who repeatedly neglect to use their turn signals will eventually receive a short display message reminding the driver to use turn signals in the future. As the driver improves his or her use of turn signals, the reminders will cease to be displayed. Conversely, drivers who use turn signals most of the time will not receive a message. In fact, those drivers may never even realize that the reminder system is designed into the vehicle.

"Most drivers do indeed use turn signals prudently and will simply never receive a reminder message in the life of the vehicle and this is a very important aspect of the system. There's no intrusion whatsoever for nearly all drivers" says Ponziani. "But if you are a chronically neglectful turn signal user, the good news is you'll quickly develop better and safer turn signal usage habits" he added.

Intelliturn is a cost effective system and this is in part achieved by utilizing existing sensor components already on most vehicles today, and integrated into vehicle networks and licensed at the OEM level. The traditional steering column trip mechanism can be eliminated with this system, reducing cost and part content. In most cases, the smart turn signal system adds little or no overall cost to most vehicles. The familiar turn signal lever remains in the same location for the driver, but ergonomics and performance are improved. Intelliturn has received documented approval from the National Highway Traffic Safety Administration for use on cars and trucks sold in the U.S.

Cars, trucks, buses, military, commercial and private vehicles can all benefit since they all have turn signals. A turn signal is only effective if it is used and it remains the duty of the driver to use it. Commercial vehicle owners will particularly appreciate that with Intelliturn, there is a level of assurance that the vehicles in their fleets out on the roads will consistently display proper turn signals to surrounding drivers. Accident rate reduction improves the bottom line profit but more importantly, injury and deaths rates can be reduced.
