Abstract: In a vehicle, GV control and M+ control are executed by generating braking/driving forces from a brake hydraulic pressure control device and a drive device during steering. A controller estimates (calculates), by a posture estimation unit, a pitch amount and a roll amount (predicted pitch rate and predicted roll rate) that occur in the vehicle through use of a moment command of the M+ control and a longitudinal G command of the GV control. The controller adjusts damping forces of damping force variable dampers through use of the estimated pitch amount and the estimated roll amount (predicted pitch rate and predicted roll rate) so that a pitch amount calculated by a pitch control unit and a roll amount calculated by a roll suppression unit approach respective target values.

Abstract: A vehicle control system for a vehicle may include a controller, a single pedal and a torque control module. The controller may be operably coupled to components and/or sensors of the vehicle to receive information indicative of operational intent of an operator of the vehicle and information indicative of vehicle status. The single pedal may be configured to provide the information indicative of operational intent. The torque control module may be configured to generate both a propulsive torque request and a braking torque request based on the information indicative of the operational intent and the information indicative of vehicle status.

Abstract: A vehicle turning control device and a method thereof are disclosed. A saturated rear-wheel lateral offset angle when a rear-wheel lateral force is saturated in turning of a vehicle is obtained from a control state amount and a motion state amount of the vehicle detected. An actual rear-wheel lateral offset angle, and a vehicle body lateral offset angular speed, are calculated from the motion state amount. A first correction amount for correcting a comparison value of the saturated rear-wheel lateral offset angle and the actual rear-wheel lateral offset angle is calculated from speed. A second correction amount for correcting the vehicle body lateral offset angular speed is calculated from the speed and the first correction amount. A target yaw momentum is calculated from the saturated rear-wheel lateral offset angle, the actual rear-wheel lateral offset angle, the comparison value, and the vehicle body lateral offset angular speed.

Abstract: 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.

Abstract: A method of automatically controlling the speed of a vehicle as the vehicle traverses a water obstacle. The method includes the step of detecting that the vehicle has entered a water obstacle. The method further includes the step of determining a depth of the water proximate the vehicle based on readings or information received from, for example, one or more sensors or other components of the vehicle. And when the depth of the water exceeds a predetermined depth, the method still further includes the step of automatically reducing the speed of the vehicle such that a bow wave created in the water by the vehicle propagates ahead of the vehicle and in an intended direction of travel of the vehicle. A system for implementing the methodology is also provided.

Abstract: An output control system incorporated in a vehicle including a clutch device comprises an upper limit setting section which sets an upper limit value of an output of the drive source to a starting control upper limit value when the output control system is performing a starting control; and a wheelie determiner section which determines whether or not a wheelie is occurring in the vehicle when the output control system is performing the starting control, wherein when the wheelie determiner section determines that the wheelie is occurring, the output control system performs a wheelie suppressing control for suppressing the output of the drive source while maintaining the starting control in such a manner that the output becomes less when the wheelie determiner section determines that the wheelie is occurring than before the wheelie determiner section determines that the wheelie is occurring.

Abstract: A straddled vehicle includes a front wheel, a rear wheel, an engine which generates a driving force and rotates the rear wheel with the driving force, a front wheel brake and a rear wheel brake which lowers the rotation speed of at least the rear wheel, a first detector which acquires and outputs a pitch rate, a second detector which detects and outputs information concerning rotation of the front wheel, and an ECU including a front wheel lift determination circuit which monitors respective outputs from the first detector and the second detector to determine whether a front wheel lift exists based on at least one of the pitch rate and information concerning rotation of the front wheel. When the front wheel lift exists, the ECU controls the driving source or the braking device so that the driving force is lowered or the rotation speed of the rear wheel is lowered.
