AI Technical Summary
Technical Problem
Existing vehicle control systems struggle to accurately determine when wheels come into contact with steps, particularly at low speeds, leading to delayed braking or driving force application, which can result in wheels going over wheel stops.
Method used
A control device that calculates the locus angle of the wheel rotation center axis using driving force and acceleration, allowing for precise estimation of step height and appropriate control of driving force and braking.
Benefits of technology
Enables quick and accurate determination of whether to apply braking or driving force when wheels encounter steps, preventing wheels from going over obstacles and ensuring safe vehicle operation.

Abstract
To provide a control device and a program for the control device which can perform control adequately when a wheel contacts a step.SOLUTION: A control device 10 comprises: a driving force acquisition part 11 which acquires driving force applied by a vehicle 100 to a road surface; an acceleration acquisition part 12 which acquires acceleration along a direction of travel of the vehicle 100; and an angle calculation part 13 which calculates, on the basis of the driving force and the acceleration, a trajectory angle θ being an angle with respect to the road surface, of a trajectory of rotation central axis AX of the wheels 111, 112 included in the vehicle 100.SELECTED DRAWING: Figure 2
