The purpose of the present invention is to provide a device and method for controlling vehicle motion and a vehicle equipped with the device, such that driving force and/or braking force is properly distributed between front wheels and rear wheels so that steering characteristics are made suitable and controllability and stability improve. This device comprises a means for controlling braking and/or driving force distribution between the front wheels and rear wheels of a vehicle such that when the absolute value of lateral acceleration of the vehicle increases, the distribution to the front wheels is made smaller, and when the absolute value of lateral acceleration of the vehicle decreases, the distribution to the front wheels is made larger.

A braking control method for a vehicle is provided. The vehicle distributes and transmits a driving force of a vehicle driving source to front and rear wheels based on a power distribution rate. The method includes determining a total braking force based on a brake signal corresponding to brake pedal manipulation, calculating a front and rear wheel braking force satisfying the total braking force, and calculating a regenerative and frictional braking force satisfying the total braking force. The method further includes determining a power distribution rate range to the front and rear wheels during braking using the calculated front and rear wheel braking force and regenerative braking force, determining a power distribution rate to the front and rear wheels based on a vehicle driving condition, within the determined power distribution rate range; and adjusting distribution of the power to the front and rear wheels at the power distribution rate.

A hybrid vehicle has an internal combustion engine, at least two electric motors, at least four wheels, a first axle and at least a second axle. Two of the wheels are associated with each axle. The internal combustion engine is provided for driving the wheels of the first axle, and the two electric motors are provided for driving respective wheels of the second axle.

Disclosed herein are systems, gearing assemblies and methods for controlling a differential rotation rate between shafts of a vehicle using a variable speed motor. An embodiment includes a gearing assembly including a differential configured to engage a first axle shaft, a second axle shaft, and a drive shaft of a vehicle. The gearing assembly further includes a plurality of adjustment gears configured to engage the differential, configured to be driven by a variable speed motor of the vehicle, and configured to controllably alter a rotation of the first axle shaft relative to the second axle shaft based on rotation produced by the variable speed motor. The plurality of adjustment gears includes a subassembly of planetary gears including a planetary gear carrier, a first set of planetary gears coupled to the planetary gear carrier, and a second set of planetary gears coupled to the planetary gear carrier.

A control apparatus for a four-wheel-drive vehicle is configured to, during braking of the vehicle in a two-wheel-drive state, determine whether or not a degree of a yaw movement for deflecting the vehicle is larger than a predetermined first degree. When the degree of the yaw movement is larger than the first degree, the control apparatus increases a first coupling torque of a first coupling device and a second coupling torque of a second coupling device to a predetermined first torque value which is larger than zero, and controls a ground contact load adjusting device in such a manner that a first ground contact load at a rear wheel at an outer side with respect to the yaw movement becomes larger than a second ground contact load at a rear wheel at an inner side with respect to the yaw movement by a predetermined first load difference or more.

A motor vehicle controller configured to: receive a drive demand signal indicating an amount of net drive to be applied to one or more driving wheels of a vehicle, estimate a value of a parameter indicative of a surface coefficient of friction between one or more driving wheels and a driving surface, and apply a net torque to one or more wheels of a vehicle. The amount of net torque applied is determined in dependence at least in part on the received drive demand signal. The controller is configured to increase an amount of net torque applied to one or more driving wheels independently of the drive demand signal and to update an estimate of the parameter in dependence on a change in speed of the at least one driving wheel when the amount of net torque applied to the at least one driving wheel is increased.

A vehicle control apparatus is mounted on a vehicle, which includes an engine and a motor configured to start the engine. The vehicle control apparatus is provided with: a first controller programmed to perform a departure prevention control, which is to prevent the vehicle from departing from a driving lane, when the vehicle is about to depart from the driving lane; and a second controller programmed to perform an automatic stop control, which is to automatically stop the engine on condition that a predetermined stop condition is satisfied, and which is to operate the motor and to restart the engine on condition that a predetermined start condition is satisfied after the engine is automatically stopped. The first controller is programmed to prohibit a start of an automatic stop of the engine by the automatic stop control, when the vehicle is about to depart from the driving lane.

A vehicle comprising a steering axle, a steering device configured to steer the steering axle, wherein a steering wheel angle can be input via the steering device, wherein the steering wheel angle leadings to a steering angle of wheels of the steering axle, and a quotient of the steering wheel angle to the steering angle defines a steering ratio, a first drive, wherein the first drive allows a wheel-selective distribution of a first torque to the wheels of the steering axle, a second drive, wherein the second drive allows a wheel-selective distribution of a second torque to the wheels of a drive axle, and a controller configured to receive input variables defining driving dynamic variables of the vehicle, wherein the drive dynamic variables allow a change in the steering ratio to ascertained, and the controller outputs control information for distributing the drive torque.
