    摘要： An angular velocity detection device is provided for detecting an angular velocity about a single axis tilted in a longitudinal direction of a vehicle to a normal axis thereof. An actual motion state variable of the vehicle is calculated on the basis of the detected angular velocity. At least one of the braking force and driving force applied to a vehicle is controlled to stabilize a yawing motion and a rolling motion of the vehicle, on the basis of a motion state variable deviation between a desired motion state variable and the actual motion state variable, e.g., a deviation between a yaw velocity and a roll velocity of the vehicle.

    摘要： A power steering apparatus is provided to generate an assistant force corresponding to a change of viscous friction in the steering unit or the like, without losing information on reaction force from a road surface. An external force calculation portion calculates an external force, that is, a force other than a force for steering (i.e. a steering force) among forces (action forces) acting on the steering unit of a vehicle. The external force is assumed to be composed of an outside force received from the road surface, such as an SAT (self-aligning torque), and an internal drag resulting from a viscous friction generated in the steering unit, and the like and these two forces are separated in an outside force and internal drag calculation portion. In separating these two forces, under the assumption that the outside force is a function of a side slip angle and an internal drag is a function of a steering angular velocity, and coefficients of functions are obtained. On the basis of the thus calculated internal drag, a motor control portion controls a motor so as to generate an adequate assistant force.

    摘要： A target value for yaw angle velocity gain is computed according to a map expressing a relationship between steering wheel angle and yaw angle velocity gain predetermined such that a direction as seen from a driver of a target destination point for vehicle travel at a predetermined time after a forward gaze and a direction as seen from the driver are caused to match each other, and a steering gear ratio is controlled accordingly. A target value for a steering wheel torque corresponding to the detected steering wheel angle and the acquired yaw angular velocity is set, based on a relationship between yaw angular velocity and resistance-feel level predetermined such that the resistance feel level for a driver monotonically increases with increasing yaw angular velocity. Control is then preformed so as to realize the steering wheel torque target value.

    摘要： The invention provides a vehicle motion control device capable of realizing optimum avoidance control in the case of an emergency. The vehicle motion control device includes an external environment detection unit for detecting external environment, and a travel state detection unit for detecting a travel state of a driver's vehicle. An obstruction is detected based on the external environment detected by the external environment detection unit, and an environment map indicating obstructions is created. A control device estimates a plurality of possible avoidance actions for avoiding an obstruction based on the environment map and the travel state of the driver's vehicle detected by the travel state detection unit. The control device estimates collision damage according to each avoidance action estimated by the avoidance action estimation unit, and selects an appropriate avoidance action based on the estimated collision damage. The control device controls a vehicle such that the selected avoidance action is carried out.
