METHOD AND SYSTEM FOR ESTIMATING SURFACE ROUGHNESS OF GROUND FOR AN OFF-ROAD VEHICLE TO CONTROL GROUND SPEED 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. 10 Steering ~40 Steering 1 Y Controller 42 System Location-Determining 153 Propulsion ~'4 Propulsion -J Receiver U Controller 46 System 12\ -- 13 Braking 48 Braking Controller 50- System Vehicle Data Bus r~l ------ , --- 510 509 1522 524 1 L__J LJL J L___ Wheel Angle 51 16 ------------- 18 Sensor51) Sensor_ Data Ports Electronic Data Inertial Sensor Module Processor Roll Sensor .156 20 25 7356 7 PitchSensor r256 2 e ____ -_a 56 53 Daaiussplay Rotational -52 | U Speed Sensor ----------- '---_------, (e.g., Drivetrain | Accelerometer(s) 54_54 Sensor) | Gyroscope 55 22 Inertial Measurement Unit Data Storage 26 GuidanceModule 24 Device Surface Roughness Estimator 57 Wheel Slip Estimator 58 c------------------------,- 59 1i -- Ground-Speed-Module jr Surface Roughness Management 76 Module -6 J- Surface Roughness Index 62 FIG. 1A Estimator
