  • Patent number: 11285809
    Abstract: Disclosed is a travel control apparatus for a four-wheel drive vehicle in which the states of engagements between a drive output part for secondary drive wheels and left and right secondary drive wheel axles are each changed to a torque transmission state or a torque transmission interruption state. The ratio of rotational speed of the drive output part to the average of rotational speeds of primary drive wheels is greater than 1. When the engagement states corresponding to the secondary drive wheels on the outer and inner sides of a turning locus have been set to the torque transmission state and the torque transmission interruption state, respectively, the engagement state having been set to the torque transmission state is changed to the torque transmission interruption state upon determination that an accelerator pedal is not operated and the magnitude of lateral acceleration is equal to or greater than a predetermined threshold.

  • Patent number: 11155162
    Abstract: Disclosed is a travel control apparatus applied to a vehicle which includes two coupling apparatuses individually changing coupling torques between a drive output part for secondary drive wheels and left and right secondary drive wheel axles and in which the ratio of rotational speed of the drive output part to the average of rotational speeds of primary drive wheels is greater than 1. The apparatus generates a yaw moment in a turning direction by using driving force. When a demand of further increasing the yaw moment arises, the control apparatus renders the braking force of the primary drive wheel on the turning locus inner side coincident with a target braking force changing with the travel state of the vehicle and decreases the coupling torque of the coupling apparatus corresponding to the secondary drive wheel on the turning locus outer side. As a result, generation of an anti-spin moment is avoided.

  • Patent number: 10926794
    Abstract: A vehicular behavior control apparatus in which a control unit that controls a driving device and a braking device is configured to calculate a target yaw moment and a target deceleration of the vehicle for ensuring stable behavior of the vehicle during non-braking turning, to calculate a first vehicle longitudinal force applied to a turning inner wheel to achieve the target yaw moment and a second vehicle longitudinal force necessary to achieve the target deceleration, to control, when the first vehicle longitudinal force is equal to or less than the second vehicle longitudinal force, the driving device so as to generate a driving force equal to a value obtained by subtracting the second vehicle longitudinal force from a driver-requested driving force and adding the first vehicle longitudinal force, and to apply the first vehicle longitudinal force to the turning inner wheel.
