The control device includes a road surface axial force calculation circuit that calculates a road surface axial force, based on road surface information. The control device includes a second estimated axial force calculation circuit that calculates a lateral force applied to a rack shaft, based on a yaw rate and a lateral acceleration. The control device includes a grip factor calculation circuit that calculates a grip factor, based on the road surface axial force and the lateral force. The control device varies the steering reaction force in accordance with the grip factor.

摘要： Systems, methods, and apparatuses are provided for determining an optimal warning distance for a vehicle. For example, the geographic location of the vehicle is received along with a reaction profile of the operator of the vehicle. Based on the geographic location, a roadway condition is determined. An optimal warning distance is then determined based on a braking distance of the vehicle and the reaction profile of the operator of the vehicle. The operator of the vehicle, or a navigation system of the vehicle itself, is alerted to the roadway condition when the vehicle is located at the optimal warning distance.

摘要： An object is to provide an attitude control system that can suppress an understeering characteristic when a vehicle such as an automobile travels in a medium-speed or low-speed range. A vehicle drives front wheels, and controls steering angles of the front wheels and steering angles of rear wheels. In an attitude control system to be mounted on the vehicle, a control amount detecting unit detects an operation amount of an accelerator pedal operated by a driver of the vehicle. A driving force estimating unit estimates a driving force generated on the front wheels based on the operation amount of the accelerator pedal. A rear-wheel steering angle determining unit determines a rear-wheel steering angle instruction value for controlling steering angles of the rear wheels based on an estimated front-wheel driving force that is the driving force estimated by the driving force estimating unit.

摘要： A slip control system for an off-road vehicle includes a control system configured to output a signal indicative of a first action if a magnitude of slippage of the off-road vehicle relative to a soil surface is greater than a first threshold value and less than or equal to a second threshold value. Furthermore, the control system is configured to output a signal indicative of a second action, different than the first action, if the magnitude of slippage is greater than the second threshold value.

摘要： An acquisition part acquires the rotational speeds of a plurality of driving wheels of a moving vehicle, and normal reaction forces acting on the plurality of driving wheels. Subsequently, a friction coefficient information calculation part calculates friction coefficients relating to the plurality of driving wheels on the basis of torque command values for the plurality of driving wheels transmitted from a torque control part and the results of acquisition by the acquisition part. A slip ratio calculation part calculates the slip ratios of the plurality of driving wheels on the basis of the calculated friction coefficients, and the rotational speeds acquired by the acquisition part. Consequently, the slip ratios of the respective driving wheels are easily, rapidly, and accurately estimated.
