Abstract
We have started basic research on a motion control system based on human driving maneuvers with the aim of developing a new vehicle motion control system that has an affinity for those maneuvers. Such a system could offer drivers perspectives on right operations and prevent their skills from degenerating. Our goal is to extract information about excellent sensing, judgment, and operation capabilities of humans and to emulate them in control systems. Jerk, the first derivative of acceleration, is information that can be sensed by the human body directly, and reflects the force changes applied to the vehicle. We are aiming at the application of jerk information to vehicle motion control. In this paper, we report our study of some techniques for measuring jerk and evaluating it to understand voluntary driving actions by using the information obtained. We have a jerk sensor that detects jerk precisely enough for this purpose by using the law of electromagnetic induction. From voluntary braking and vehicle turning driving tests, we confirmed that drivers select the timing for these actions when either longitudinal or lateral motion of a vehicle is momentarily in a stationary state (i.e., jerk zero point) and start to steer or accelerate at this timing.
