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： Various state amounts of a vehicle body detected by various types of sensors are captured (step 102). A maximum frictional force Fimax is calculated for each of wheels (steps 104 to 110). By use of the maximum frictional force Fimax and other physical quantities, a performance function not dependent on respective magnitudes of a vehicle body generating force and a yaw moment is defined, which performance function is prepared by means of a performance function in a case in which the vehicle body generating force is larger than the yaw moment, and a performance function in a case in which the vehicle body generating force is not larger than the yaw moment (step 112). A resultant force qi of tire generating forces acting on respective wheels is calculated by means of a third performance function (step 114), and braking and driving forces of each wheel, and a steering angle of each wheel are obtained by means of the calculated direction in which the resultant force of tire generating forces acts on the wheels (step 116). Based on the obtained braking and driving forces and steering wheel of each of the wheels, these wheels are each controlled (step 118).

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： In accordance with a vehicle motion control apparatus, a steering angle (θh) of a steering wheel is determined on the basis of a rotation angle (θpm) of an assist motor (24m) detected by a rotation angle sensor (24s) and a rotation angle (θvm) of a gear ratio variable motor (32m) detected by a rotation angle sensor (32s), and a VGRS control process (40a) of a gear ratio variable mechanism is executed on the basis of the determined steering angle (θh). Accordingly, since the steering angle (θh) of the steering wheel is determined on the basis of the rotation angle (θvm) used for the VGRS control process (40a) of the gear ratio variable mechanism and the rotation angle (θpm) used for an EPS control process (30a) of an EPS actuator, it is possible to obtain the steering angle (θh) of the steering wheel without a steering angle sensor. Therefore, it is possible to reduce the number of the parts of a vehicle motion control apparatus.

摘要： In a steering apparatus, in accordance with a grip limit control process (30b′), it is determined whether or not a grip degree ε estimated by a grip degree estimation arithmetically operating process (30a) is less than a predetermined grip degree (ε′), and in the case that it is determined that an estimated grip degree (ε) is less than the predetermined grip degree (ε′), the process applies such a feeling that a steering operation by a steering wheel suddenly becomes light to a driver, by suddenly increasing an assist quantity by a motor (M), thereby notifying the driver of the matter that the grip degree of a steered wheel is close to a limit. Therefore, it is possible to transmit to the driver a probability that a side slip is generated by further turning the steering wheel 21 in the same direction as the current direction, thereby calling the driver's attention for steering. Accordingly, there is an effect that a stability of a vehicle behavior can be improved without applying any fear of insecurity to the driver.
