摘要： A steering control apparatus is provided for a vehicle having a steering wheel for steering steered wheels of the vehicle, a power source for generating power, and drive shafts for transferring the power to the steered wheels, to be served as driving wheels of the vehicle. The apparatus comprises an accelerating operation detection device for detecting accelerating operation amount by a vehicle driver, and a steering torque control device for controlling steering torque created by the steering wheel, and applying torque steer reducing torque to the steering wheel. The steering torque control device is adapted to reduce torque steer, which is transiently created on the steering wheel due to characteristics of the drive shafts, when the accelerating operation amount detected by the accelerating operation detection device becomes equal to or greater than a predetermined value.

摘要： A steering device is provided for controlling steering torque applied to a steering wheel of a vehicle. A braking device is provided for controlling longitudinal force applied to each wheel, and a control device is provided for performing at least one of an anti-skid control and a traction control. It is observed whether the control device is performing the control on a split road surface. The steering torque is controlled on the basis of a difference of longitudinal force applied to the right and left wheels, and a turning state amount deviation between a turning state amount and a desired amount thereof. The desired amount of turning state is calculated, on the basis of the turning state of the vehicle obtained when one of the anti-skid control and the traction control is performed on the split road surface.

摘要： In rollover prevention control, an inner front wheel braking force is generated only in a front wheel located on the radially inner side of a turning locus in a relatively early stage where the absolute value of actual lateral acceleration is between a first value and a second value. When the absolute value becomes greater than the second value, in addition to the inner front wheel braking force, an inner rear wheel braking force is generated in a rear wheel located on the radially inner side of the turning locus. When the absolute value becomes greater than a third value, in addition to the inner rear wheel breaking wheel, an outer wheel braking force is generated in the front wheel located on the radially outer side of the turning locus. Thus, an increase in the roll angle is suppressed, and a desired turning locus tracing performance is maintained satisfactorily.

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 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： The present invention is directed to an unpaved road detection system wherein a slip rate is calculated on the basis of wheel speeds detected by wheel speed sensors and a vehicle speed detected by a vehicle speed detection device. A linear acceleration sensor is provided for detecting an acceleration of the vehicle in a longitudinal direction thereof to produce a signal linearly proportional to the detected acceleration. A variation of the signal produced by the linear acceleration sensor corresponding to the variation of the slip rate is calculated. The variation of the signal is compared with a reference value. If the variation exceeds the reference value, it is determined that the vehicle is traveling on an unpaved road. The variation may be provided by calculating a difference between a first signal detected by the linear acceleration sensor when the slip rate exceeded a first reference rate, and a second signal detected by the linear acceleration sensor when the slip rate exceeded a second reference rate.

摘要： The present invention is directed to an apparatus for estimating the peak of a coefficient of friction in a coefficient of friction—slip rate characteristic, wherein a wheel acceleration of each wheel of a vehicle is detected, and a vehicle acceleration of the vehicle is detected. A peak estimation device is provided for estimating the peak of the coefficient of friction, and adapted to determine that the coefficient of friction is the peak when the wheel acceleration is lower than the vehicle acceleration, by more than a predetermined difference. An anti-skid control system for an automotive vehicle may be formed to include the coefficient of friction peak estimation apparatus, and a reference speed setting device for setting a reference speed for initiating a pressure decrease mode on the basis of a wheel speed and a vehicle speed detected when the peak was detected. A pressure control device is disposed between a wheel brake cylinder and a pressure generator, to be controlled in response to at least the result of comparison between the wheel speed and the reference speed.

摘要： In neutralizing an acid addition salt of .alpha.-APM in an aqueous medium, the .alpha.-APM concentration in the neutralized liquid is controlled to fall within the range of from 3 to 10 wt. % at the finish of neutralization. Then, the liquid is heated to 50.degree. to 80.degree. C. and neutralization is effected with stirring to the isoelectric point of .alpha.-APM; or after the neutralization, the neutralized liquid is heated. The neutralized liquid is thereafter cooled with or without stirring so that crystals of .alpha.-APM are precipitated.
