This paper presents a two-sensor method to enhance the nighttime driving safety. It consists of two accelerometers and an array of auxiliary swiveling headlamps. An alpha beta filter is proposed to stabilize the readings of the accelerometers. With the kinematics of a turning car, the cars turning path is predicted based on the steering angle measured by the accelerometers so that the relevant auxiliary swiveling headlamps will be switched on accordingly. In this paper, the authors will study the performance of the alpha beta filter. Test results demonstrate that this angular measurement method is an efficient way for proper road illumination along curved paths.
