Nissan Develops a New Adaptive Cruise Control (ACC) System With Low Speed Following Capability

Tokyo -- Nissan Motor Co., Ltd., today announced the development of a new Adaptive Cruise Control (ACC) system with low speed following capability.  The system is designed to reduce the driver's workload in low-speed driving situations, such as in congested traffic. The new ACC system is tentatively planned to be adopted on a new luxury model to be released next year.

Compared with the conventional ACC system*, this newly developed system can automatically hold the headway distance to a preceding vehicle constant according to the driving speed, even at slow driving speeds of below 40km/h.  This newly added function lessens the driver's need to accelerate or decelerate frequently.  
* The ACC system automatically maintains the headway distance to a preceding vehicle according to the driver's preset distance by controlling the throttle and brake, based on distance and speed information measured with radar sensor.

Nissan has conducted public road tests in Japan since 2001, as approved by the Minister of Land, Infrastructure and Transport. The system has been developed using road-test data on actual traffic systems and driver's actions when driving at lower speeds. This system is one achievement of ASV (Advanced Safety Vehicle) technology development.

An illustration of the low speed following system is given below:
