A method and system for estimating surface roughness of a ground for an off-road vehicle to control ground speed comprises detecting motion data of an off-road vehicle traversing a field or work site during a sampling interval. A pitch sensor is adapted to detect pitch data of the off-road vehicle for the sampling interval to obtain a pitch acceleration. A roll sensor is adapted to detect roll data of the off-road vehicle for the sampling interval to obtain a roll acceleration. An electronic data processor or surface roughness index module determines or estimates a surface roughness index based on the detected motion data, pitch data and roll data for the sampling interval. The surface roughness index can be displayed on the graphical display to a user or operator of the vehicle, or applied to control or execute a ground speed setting of the vehicle.

A device detects a behavior of a straddle-type vehicle in a yaw direction and in a roll direction, determines whether a traveling state of the straddle-type vehicle is a first state or a second state closer to a straight traveling state than the first state, and estimates a turning radius of the straddle-type vehicle. In a case where it is determined that the traveling state is the first state, a turning radius is estimated by a first method based on a detection result of the behavior in the yaw direction. In a case where it is determined that the traveling state is the second state, the turning radius is estimated by a second method based on a detection result of the behavior in the roll direction.
