Based on information from a laser radar attached to the front of the vehicle, this system maintains a set following distance that corresponds to a stable vehicle speed (approx. 40 to 100 km/h) or provides low speed running at a set speed when there is no vehicle in front.

Storage location:Nissan Motor Co., Ltd.
dot
Year manufactured:2004
dot
Manufacturer:Nissan Motor Co., Ltd.
dot
Classification:Mass-production system
dot
Familiar name:Intelligent Cruise Control
dot
Technical applications:When the system judges that vehicle is deviating from the lane, the indicator flashes together with a warning sound to inform the driver.
dot
Applied model:Passenger vehicles
dot
Year manufactured:2004

Application year:2004

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, and a controller that performs control and computing
dot
Performance function:The low speed following function was newly added to a conventional following distance automatic control system for speeds of approximately 40 to 100 km/h (possible speed settings). When the vehicle is running at low speeds of approximately 40 km/h or below, the following distance to the vehicle in front can be maintained
dot
Effect:Because of the addition of the low speed following function, the driving load of the driver can be reduced not only at high speeds but also at low speeds in traffic congestion.
dot
Points of interest, topicality:JSAE Technical Development Award in 2005
dot
Features:Driver burden is reduced not only at high speeds but also at low speeds in traffic congestion and the like.
When the sensor detects a vehicle in front in the same lane
See Figure 2
When the driver switches on the system when driving at approx. 10 to 40 km/h, the vehicle maintains the following distance in accordance with the vehicle speed with an upper limit of 40 km/h.
*Operation is stopped when no vehicle is detected in front.

When the vehicle in front decelerates
See Figure 3
When a brake operation is required, the display and the buzzer are used to inform the driver. When the vehicle speed decreases to approximately 5 km/h or below, the operation is stopped and the display and the buzzer are used to inform the driver.
It is possible to automatically switch from the intelligent cruise control to the low speed following functions, which further improves convenience.

Switching from intelligent cruise control to the low speed following function
See Figure 4
When the vehicle is following under the intelligent cruise control, the setting is automatically switched to the low speed following function when the vehicle speed falls below approximately 35 km/h.

Switching from the low speed following function to intelligent cruise control.
See Figure 5
When the vehicle is following under the low speed following function with an intelligent cruise control speed set, the setting is automatically switched to intelligent cruise control when the vehicle speed reaches approx. 40 km/h.
*Each figure shows typical driving scenarios.

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.
