A method of applying a brake force to all four wheels of a motor vehicle to stop the vehicle while torque continues to be applied to its driven wheels; and preventing wheel slippage of the driven wheels by reducing the applied torque when the vehicle is stopped or nearly stopped from moving in a forward direction. In this way, unintentional lateral movement of the vehicle due to creep torque applied to the driven wheels on slippery surfaces can be prevented or corrected.

A vehicle driving assistance device has an estimation unit for separately estimating the temperatures of the braking portions in the left and right drive wheels, a first execution unit for executing vehicle stabilization control for separately controlling the braking forces exerted on the vehicle wheels, and a second execution unit for executing turning assist control for exerting braking force on the inside drive wheel of the left and right drive wheels when the vehicle is turning while vehicle stabilization control is not being executed. During turning assist control, the braking force exerted on the inside drive wheel when the difference in pad temperatures between the left and right drive wheels is equal to or greater than a reduction determination value is reduced to a greater extent than the braking force exerted on the inside drive wheel when the pad temperature difference is less than the reduction determination value.

A method of controlling the deceleration of a vehicle to account for an increase in friction in the vehicle brake system as the vehicle decelerates. The method comprises receiving a signal indicative of a value of the speed of the vehicle and a signal indicative of a value of a brake pressure in the vehicle brake system. The method further comprises comparing the vehicle speed value and the brake pressure value to respective thresholds. The method still further comprises increasing the drive torque applied to one or more wheels of the vehicle when the vehicle speed value falls below the threshold to which it was compared and the brake pressure value exceeds the threshold to which it was compared, such that the increased drive torque acts against the braking of the vehicle as the vehicle is decelerated to a stop.

In order to achieve a vehicle wheel (10) slip relative to a roadway (12) while braking the vehicle, said slip being as advantageous as possible, the rotational speed (w) of the wheel (10) can be actively reduced by an ABS by means of a braking intervention and passively allowed to accelerate again via the roadway (12) when the brake is released. The slip of the wheel (10) oscillates by an optimal slip value during the ABS regulating process. The aim of the invention is to improve an anti-lock braking system for a vehicle. In the method according to the invention, at least one wheel (10) of the vehicle is supplied with a braking torque (Mb) in order to temporarily reduce a travel speed (v) of the vehicle relative to a rolling surface (12), said braking torque acting against a rotating direction (14) of the wheel (10). Additionally, the wheel (10) is temporarily supplied with an acceleration torque (Ma) by means of an accelerating device of the vehicle during the reduction of the travel speed (v), said acceleration torque acting in the rotating direction (14).

A vehicle electronic stability control system which allows a vehicle to have improved movement performance and limit performance without causing a driver to feel uncomfortable, by actuating electronic stability control from a state where a lateral slip is relatively less likely to occur. The system prevents a skid of a vehicle. The system is provided with a stability determination module that obtains information indicating vehicle behavior from a sensor, and determines whether the vehicle is in an unstable or less stable state, on the basis of the information. The system is further provided with a braking/driving force control module which, when the stability determination module determines that the vehicle is in the unstable or less stable state, applies a braking force to one of the drive wheels, and simultaneously applies a driving force to the motor for the other drive wheel.

A vehicle includes a first axle system operatively connected to a first set of wheels, a second axle system operatively connected to a second set of wheels, a first drive system operatively connected to the first set of wheels, a second drive system operatively connected to the second set of wheels independent of the first set of wheels, and a traction management control module electrically coupled to at least one of the first and second drive systems. The traction management control module calculates a torque capability of the corresponding one of the first and second axle systems and selectively transmits an axle torque command to the corresponding one of the first and second axle systems based on the torque capability.

A vehicle combination comprising a tractor vehicle and a trailer vehicle, each vehicle including wheels on different sides of the vehicle and wheel brakes associated with the wheels. A method for controlling the vehicle combination includes determining a yaw rate difference between a yaw rate of the tractor vehicle and a yaw rate of the trailer vehicle; determining, on the basis of the yaw rate difference, that an orientation of one of the vehicles deviates from an intended travel direction of the vehicle combination; and activating a wheel brake of the vehicle on only one side of the vehicle in order to counter the orientation deviation of the vehicle relative to the intended travel direction.

A method of controlling the deceleration of a vehicle to account for an increase in friction in the vehicle brake system as the vehicle decelerates. The method comprises receiving a signal indicative of a value of the speed of the vehicle and a signal indicative of a value of a brake pressure in the vehicle brake system. The method further comprises comparing the vehicle speed value and the brake pressure value to respective thresholds. The method still further comprises increasing the drive torque applied to one or more wheels of the vehicle when the vehicle speed value falls below the threshold to which it was compared and the brake pressure value exceeds the threshold to which it was compared, such that the increased drive torque acts against the braking of the vehicle as the vehicle is decelerated to a stop.

A method of managing the deceleration of a vehicle. The method comprises receiving a brake command and determining an actual rate of deceleration of the vehicle. The method further comprises monitoring the speed of the vehicle as the vehicle decelerates in response to the brake command. The method still further comprises modifying the amount of brake torque being applied to one or more wheels of the vehicle when the vehicle speed reaches a predetermined threshold, by first decreasing the amount of brake torque being applied and then subsequently increasing the amount of brake torque being applied to bring the vehicle to a standstill. A system for implementing the methodology is also provided.

A vehicle control system for reducing turn radius of a vehicle may include a controller and a torque control module operably coupled to the controller and to front wheels of a front axle of the vehicle and rear wheels of a rear axle of the vehicle. The controller may also be operably coupled to components and/or sensors of the vehicle to receive information including vehicle wheel speed and steering wheel angle. The torque control module may be operable, responsive to control by the controller, to apply a negative torque to an inside rear wheel during a turn and apply a positive torque to the front axle during the turn to compensate for the negative torque applied to the inside rear wheel to reduce the turn radius based on the steering wheel angle and the vehicle speed.
