Abstract: During vehicle turning, during which a behavior stabilization control is not carried out, a vehicle driving assistance device carries out a turning assist control including: yaw moment control for increasing the amount of drive torque distributed to a drive wheel that, among two left and right drive wheels of the vehicle, is on the outer side of the turn by imparting braking torque to the drive wheel that is on the inner side of the turn; and a deceleration control for decelerating the vehicle. At this time, the driving assistance device calculates a control moment amount and calculates a control deceleration amount on the basis of a travel mode selected by operation of an operation unit.

Abstract: This driving assistance device includes a braking control unit and a target speed determination unit. The braking control unit executes driving assistance control for adjusting the braking force to be applied to a vehicle by actuating a brake actuator such that the vehicle body speed does not exceed a target speed. In cases where the accelerator pedal is being operated in a state where the braking control unit is executing the driving assistance control, the target speed determination unit determines the target speed depending on the larger value of either: the vehicle body speed that is correlated with at least one of the wheel speeds of the plurality of wheels provided to the vehicle; or the lower speed limit value that has been set.

Abstract: A vehicle braking device performs a following control which makes an actual value of a physical quantity follow a first target value when the actual value of the physical quantity is a value outside a dead zone and a suppression control which suppresses a change of the actual value when the actual value is a value within the dead zone in order to control the physical quantity associated with the braking force to be the first target value. The vehicle braking device comprises a setting portion which sets a second target value which follows the first target value and which is smaller than the first target value, when the first target value is increasing and a control portion which performs a control to make the actual value approximate the second target value.
