This paper presents driving path estimation algorithm for adaptive cruise control system and advanced emergency braking system using multi-sensor fusion. Through data collection, yaw rate filtering based road curvature and vision sensor road curvature characteristics are analyzed. Yaw rate filtering based road curvature and vision sensor road curvature are fused into the one curvature by weighting factor which are considering characteristics of each curvature data. The proposed driving path estimation algorithm has been investigated via simulation performed on a vehicle package Carsim and Matlab/Simulink. It has been shown via simulation that the proposed driving path estimation algorithm improves primary target detection rate.

This paper presents an integrated driving path estimation algorithm for adaptive cruise control system and advanced emergency braking system using multi-sensor fusion. This algorithm is developed to predict the ego-vehicle’s path accurately and to improve the performance of primary target detection using the predicted path of the ego-vehicle. The path prediction consists of two prediction process; vehicle states based prediction and vision data based prediction. For application to dynamic maneuvering situations, the driving mode index which allows a detection of the driver maneuver intention is proposed. In accordance with the driving mode, the two types of driving path information are integrated finally. The proposed driving path estimation algorithm has been investigated via closed-loop simulation. It has been shown that the proposed driving path estimation algorithm enhance the capabilities of adaptive cruise control and advanced emergency braking system functions by providing the ego-vehicle’s path accurately, especially in dynamic maneuvering situation.

This paper presents a development of evaluation-basis for safety assessment of advanced cruise control system and safety evaluation from field test. Sensor performance, decision performance and control performance are derived as a evaluation-basis for safety assessment of advanced cruise control system. And fourteen test scenarios are developed for safety evaluation. The evaluation-basis are provided to each scenario. On the other hand, field car test were carried out about different cars, based on the developed test scenarios. Finally, from the test result, safety of advanced cruise control systems was evaluated, based on the developed evaluation-basis.
