Feasibility Study of a Braking Assistant System for Driver Pedal Operation in Emergency Situations

The movements of the driver's foot from the accelerator to the brake pedal in normal and emergency braking situations were recorded using VTR (Video Tape Recorder) cameras and then analyzed using the three-dimensional image processing system (Peak Motus). The displacement and velocity of driver's foot motion was also precisely measured by a CCD (Charge Coupled Device) laser displacement sensor. Data of instantaneous velocity and the elapsed time of driver's sole motion immediately after releasing the accelerator pedal were obtained. Using this information, a feasibility study of the braking assistant system was undertaken before application of the brake pedal in an emergency situation.
