  • Publication number: 20060129298
    Abstract: A start threshold value for rollover prevention control is changed based upon a ratio between an actual lateral G and a reference lateral G. Accordingly, the ratio between the actual lateral G and the reference lateral G is a parameter that indicates a vehicle condition, i.e., the potential for vehicle rollover that includes both the vehicle weight and the center of gravity height. It is therefore possible to set a start threshold value that considers the vehicle weight, center of gravity height and the like.

  • Patent number: 6059065
    Abstract: A driving torque control apparatus has a first differential restraining device which restrains a rotational speed differential between front-left and front-right wheels by adjusting driving torque to be transmitted from a power source mounted on a four-wheel drive vehicle to each of the front-left and front-right wheels, and a second differential restraining device which restrains a rotational speed differential between rear-left and rear-right wheels by adjusting driving torque to be transmitted from the power source to each of the rear-left and rear-right wheels. An adjustment of driving torque by the second differential restraining device is executed in preference to an adjustment of driving torque by the first differential restraining device.

  • Patent number: 5978726
    Abstract: A wheel speed differential with another wheel of each of several wheels is determined as a parameter for brake-adjustment use, and driving torque conveyed respectively from an engine to the several wheels is adjusted by braking torque determined on a basis of the parameter for brake-adjustment use so as to restrain the wheel-speed differential. In such a driving torque control, the engine output is reduced if the braking torque is excessive. Therefore, load to the brake apparatus and drivetrain caused by engine output can be reduced. Thus, deterioration of the durability of the brake apparatus and drivetrain can be prevented.

  • Patent number: 5636907
    Abstract: Self-suction pumps are driven to take in brake fluid from a master-cylinder side before performing brake TRC control when at a low temperature and moreover when a vehicle is stopped. During driving of these self-suction pumps, pressure-increasing control valves and pressure-reducing control valves are both opened and brake fluid is accumulated in reservoirs. Because of this, an amount of pump discharge employed in brake TRC control when at a low temperature is assured, and responsiveness of brake TRC control is enhanced.

  • Patent number: 5410483
    Abstract: A shock absorber is connected between a vehicle body and a vehicle wheel. The shock absorber provides a variable damping force. A control apparatus for the shock absorber includes an actuator for adjusting the damping force provided by the shock absorber. A vibration detecting device serves to detect a relative vibration between a spring upper member and a spring lower member. A damping-factor estimating device serves to estimate a damping factor of the shock absorber. A speed estimating device serves to estimate an absolute speed of the spring upper member on the basis of the relative vibration detected by the vibration detecting device and the damping force estimated by the damping-force estimating device. A signal setting device serves to set a drive signal of the actuator on the basis of the absolute spring upper member speed estimated by the speed estimating device.

  • Patent number: 5322320
    Abstract: A shock absorber damping force control system for a vehicle employs at least a high-frequency component included in sprung mass vibration as a factor to control a damping force of a shock absorber. The system provides a lower damping force of the shock absorber with a larger magnitude of the high-frequency component when signs of a sprung mass velocity and a relative velocity between a sprung mass and an unsprung mass coincide with each other. A low-frequency component may also be employed as a factor to control the damping force of the shock absorber. The system provides a lower damping force with a larger ratio of the high-frequency component relative to the low-frequency component when signs of the sprung mass velocity and the relative velocity coincide with each other.
