|Familiar name||:||Lane Keeping Assistance System|
|Applied model||:||Passenger vehicles|
|Designed by||:||Nissan Motor Co., Ltd.|
|Device structure||:||This system consists of the following parts: a CCD camera that recognizes the lane in front of the vehicle, a steering actuator that adds control force to the steering, an alarm buzzer, and a controller that performs control and computing|
|Performance function||:||The CCD camera mounted at the upper part of the rearview mirror is used to detect the lane, and the force necessary to make the vehicle run close to the center of the lane is calculated based on the vehicle speed and the steering angle. Part of this force is collaterally added to the steering. When this system is in operation, the indicator flashes together with a warning beep to inform the driver is the vehicle is judged to be deviating from the lane.|
In addition, the force that is gradually added to the steering is decreased when entering a curve, resulting in the addition of no force
|Effect||:||The Lane Keeping Support System supports steering operations so that the vehicle can maintain its course in the lane against the effects of road inclination and crosswinds. This system reduces the load of steering operations on the driver and improves comfort (operative vehicle speed: approx. 65 to 100 km/h).|
|Points of interest, topicality||:||JSAE Technical Development Award in 2002|
|Features||:||1. The system detects unintended deviation of vehicles from their lane and issues a warning.|
2. Gentle control closely supports driver operation.
3. Braking of each wheel is independently controlled to change the direction of the vehicle.
|Introduction||:||The Lane Keeping Support System supports steering operations so that the vehicle can maintain its course in the lane against the effects of road inclination and crosswinds, thereby alleviating driver fatigue. The first of its kind in the world, this system was installed in the Nissan Cima released in January 2001.|
