Abstract: In a stabilizer control apparatus for transmitting a power through a speed reducing mechanism, a rolling motion of a vehicle body is restrained smoothly and rapidly, without being affected by transmitting efficiency of the speed reducing mechanism. As for a stabilizer (SBf) including a pair of stabilizer bars (SBfr, SBfl) disposed between a right wheel and a left wheel, and a stabilizer actuator (FT) driven by an electric motor disposed between them, the electric motor M is controlled in response to a turning state of a vehicle, to control a torsional rigidity of the stabilizer. Furthermore, the apparatus comprises relative position detection means for detecting the relative position of the pair of stabilizer bars (for example, obtained from a relationship between a rotational angle of the electric motor and a reducing speed ratio), and it is so constituted that the electric motor is controlled in response to the detected result.

Abstract: An object of the invention is to increase driving force of driving wheels at starting a vehicle, when the vehicle runs on a μ-sprit road. At first, a road surface for a driving wheel is detected, which has a higher coefficient of friction than that of a road surface for the other driving wheel. An operation for controlling grounded load of the driving wheels is carried out during a period, in which differential rotations of the driving wheels are limited. The grounded load of the driving wheel which is traveling on a high-μ road is increased, whereas the grounded load of the other driving wheel which is traveling on a low-μ road is decreased.

Abstract: 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.

Abstract: 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.
