Abstract

The advantages and reduction in cost of the adaptive cruise control (ACC) system based on radar technology, are discussed. According to the head of the radar technology the issue is related to the economical feasibility but not the technical feasibility. The infrared ACC system is based on two new lidar ISF 100 sensors with an effective range of around 150m. The two electronically controlled headway sensors detect the cars in front with several beams and the system automatically adjusts the safety distance to the car ahead. When the driver shifts to the overtaking lane and has enough space ahead to overtake the car in front, the system controls the acceleration of the car. When the driver gets back into inside lane behind a slower car the system controls the engine management, transmission management and braking operations very smoothly. It was shown that there is a very good balance between the necessary braking force and the braking comfort for the drivers.
