    • An active suspension apparatus is provided for a vehicle which includes an actuator being extensible and retractable and provided between a vehicle body and a wheel so that the force of the vehicle body to support the wheel is adjustable, a sprung G sensor or a vehicle height sensor for detecting a vibration input to the vehicle body, and a control valve and a controller for controlling the supporting force of the actuator in accordance with the vibration input detected by the sprung G sensor or the vehicle height sensor, and thereby restraining the stroke of the actuator. The suspension apparatus further comprises a forward road surface sensor for detecting the size of irregularities of a road surface in front of the vehicle, and the control valve and the controller are adapted to execute normal control such that the equivalent spring constant of the actuator is adjusted to a first spring constant when a surface irregularity of a size larger than a predetermined size is detected by the forward road surface sensor, and to execute inverse spring control such that the equivalent spring constant of the actuator is adjusted to a second spring constant lower than the first spring constant, and thereby lengthening the stroke of the wheel, when no surface irregularity of a size larger than the predetermined size is detected by the forward road surface sensor. As a result, the ride is greatly improved when the vehicle runs on a smooth road.

    • A steering gear ratio changing apparatus includes a first and second steering shafts arranged to be coaxial with each other. The first steering shaft is coupled to a steering wheel of a vehicle and rotatable integral therewith. The second steering shaft is coupled to a steering gear mechanism and arranged to be rotatable. First pawls are formed on one end of the first steering shaft and arranged at equal intervals along the circumferential direction of the shaft. Second pawls are formed on one end of the second steering shaft, which oppose the end of the first steering shaft, and are arranged at equal intervals along the circumferential direction of the shaft. The first and second steering shafts are coupled with each other by a torsion bar and held thereby so that the first and second pawls are engage with one another with a gap between any two adjacent first and second pawls. The width of the gaps is adjusted by actuators so as to cause a relative rotation between the first and second steering shafts.

    • A first target value is set as an initial value of split point pressure, a master cylinder pressure is set as a second target value of split point pressure in a memory when ABS valves (17, 20, and 23) are operated, thereafter when a sign of locking of the rear wheels is detected, the target value is reduced even further and set in the memory, the target value is maintained for a predetermined time by timer control at every setting of a new target value, and when a braking deceleration generated while the target value is maintained in the memory, a controller (37) controls so that the target value is increased after the completion of braking. When the master cylinder pressure is higher than the target value stored in the memory, proportioning valves (26 and 27) are closed to decrease a ratio of the rear wheel braking force to the front wheel braking force, thereby always achieving appropriate control over the rear wheel braking force allocation.
