摘要: A motion control device 10 for a vehicle exerts braking force only on the rear wheel at the inner side of the turning direction for generating a yawing moment on the vehicle only in the turning direction of the vehicle when an absolute value of an actual lateral acceleration Gy is not more than a value Gyth, i.e., when there is a small possibility of the occurrence of an excessive roll angle on the vehicle body, in case where the turning state of the vehicle is the understeer state. On the other hand, it exerts braking force not only on the rear wheel at the inner side of the turning direction, but also on the front and rear wheels at the outer side of the turning direction for generating a yawing moment in the direction opposite to the turning direction too, when the absolute value of the actual lateral acceleration Gy exceeds the value Gyth, i.e., when there is a great possibility of the occurrence of the excessive roll angle on the vehicle body, in case where the turning state of the vehicle is the understeer state.

摘要: A control of a vehicle motion control device 10 is as follows during an oversteer restraining control. Specifically, when tire inflation pressure is appropriate, the device sets braking force exerted on each of front and rear wheels at the outer side of the turning direction so as to be reference braking forces Ff1 and Fr1, that are generated when an absolute value of a lateral acceleration deviation ΔGy is not less than a reference value a1 and that respectively increase up to an upper limit value ff and upper limit value fr in accordance with the increase in the absolute value of the lateral acceleration deviation ΔGy. On the other hand, when a tire inflation pressure of one of the front and rear wheels at the outer side of the turning direction is lowered, the device sets the braking force, such that the braking force starts to be generated from when the absolute value of the lateral acceleration deviation ΔGy is smaller than the reference value a1 by an amount in accordance with the reduction in the tire inflation pressure and that the upper limit value of the braking force with respect to the wheel whose tire inflation pressure is lowered is decreased by an amount in accordance with the reduction in the tire inflation pressure and that the upper limit value of the braking force with respect to the wheel that is not the wheel whose tire inflation pressure is lowered is increased by an amount in accordance with the reduction in the tire inflation pressure.

摘要: In the case where the absolute value of steering angle θs is equal to or greater than a prescribed angle, a motion control apparatus 10 for a vehicle sets a control gear ratio n in such a manner that when an estimated vehicle-body speed Vso is equal to or greater than a prescribed value, the control gear ratio n becomes a value which is equal to or greater than “20” and which increases with the estimated vehicle-body speed Vso as the absolute value of the steering angle θs increases, and when the estimated vehicle-body speed Vso is less than the prescribed value, the control gear ratio n becomes a value which is not greater than “20” and which decreases with the estimated vehicle-body speed Vso as the absolute value of the steering angle θs increases. The apparatus then calculates a target yaw rate Yrt by making use of an equation shown in Step 510 and using the control gear ratio n, and controls a braking force applied to each wheel so that the actual yaw rate Yr coincides with the target yaw rate Yrt.

摘要: When the absolute value of the steering angle equals or is greater than a prescribed angle, a vehicle motion control apparatus sets a control gear ratio so that when an estimated vehicle-body speed is equal to or greater than a prescribed value, the control gear ratio becomes a value equal to or greater than a certain value and which increases with estimated vehicle-body speed as the absolute value of the steering angle increases. When the estimated vehicle-body speed is less than the prescribed value, the control gear ratio becomes a value not greater than the certain value and which decreases with estimated vehicle-body speed as the absolute value of the steering angle increases.

摘要: A braking force distribution control device for an automotive vehicle is designed to make it possible to initiate a braking force distribution control as rapidly as possible upon rapid braking operation while at the same time being capable of preventing a malfunction of the braking force distribution control even when one of hydraulic pressure lines fails. The braking force distribution control establishes a predetermined relationship between the wheel cylinder pressure of a front wheel and a wheel cylinder pressure of a rear wheel on the basis of a comparison between the wheel speeds of the front and rear wheels. The braking force distribution control is initiated when the decelerations of all the wheels exceed a set value.

摘要: A target vehicle speed is switched between a target slip vehicle speed and a target torque vehicle speed on the basis of a result of a determination regarding whether or not a vehicle is insufficiently accelerated. More specifically, if traction control is not performed, the target slip vehicle speed is set as the target vehicle speed. If it is determined that the vehicle is sufficiently accelerated during traction control, a value obtained by subtracting a maximum permissible value from a value set last time as the target vehicle speed is compared with the target slip vehicle speed, and the larger one of them is set as the target vehicle speed this time. If it is determined that the vehicle is insufficiently accelerated during traction control, the larger one of the target slip vehicle speed and the target torque vehicle speed is compared with a value obtained by adding a maximum permissible value to a value set last time as the target vehicle speed, and the smaller one of them is set as the target vehicle speed this time.
