摘要： PROBLEM TO BE SOLVED: To roll a vehicle body inward, in turning direction, by a will of a driver, and to enable set-in roll. SOLUTION: Rear right and left wheels 2 are rockably fitted to a frame 3 by independent swing arms 6, and a hydraulic cylinder 7 is interposed between the swing arms 6 and the frame 3. A pedal 9 is disposed forward of a driver seat 21 to connect a cylinder 8 to be stepped in by the pedal 9 to the hydraulic cylinder 7. When the pedal 9 is stepped on, the rear right and left wheels 2 are pulled downward and independently. When the pedal 9 is stepped off, the rear right and left wheels 2 are pulled upward and independently. When the pedal 9 is operated to the turning direction, a vehicle body can be rolled inward in the turning direction. The set-in roll is realized by increasing the movement of the wheels to be pulled more upward than the movement of the wheels to be pulled downward. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To suppress any change of the vehicle body posture according to the deceleration or acceleration of a vehicle even when the longitudinal distribution of the braking force or the driving force is changed.
SOLUTION: When a friction brake is operated (the determination of Step S2 is "Yes"), the distribution ratio α of the braking force to a front wheel and the distribution ratio (1-α) of the braking force to a rear wheel are calculated first (Step S3). The suppressing moment Mcp for suppressing the pitching of the vehicle body associated with the deceleration of the vehicle is calculated (Step S4). The center position Lc for applying the suppressing moment Mcp is set according to the distribution ratio α so that the jack-up for elevating the sprung vehicle body position associated with the deceleration of the vehicle can be suppressed by the suppressing moment Mcp (Step S5). Front wheel shock-absorbers 2FL, 2FR and rear wheel shock-absorbers 2RL, 2RR are individually drive-controlled so that the suppressing moment Mcp is applied around the calculated center position Lc (Steps S6, S7).
