摘要： An active, resettable head restraint system includes a collision prediction system for detecting objects approaching the vehicle from the rear, a pressure tank containing a quantity of pressurized air, a motor-driven compressor for maintaining a desired pressure in the tank, and an expandable headrest. The headrest comprises a base mounted to the seat back in conventionally known fashion, a pad connected to the base for movement between a rearward pre-deployment position and a forward deployed position, and at least one inflatable bladder located between the base and the pad. The bladder is connected with the pressure tank for inflation when activated by the collision prediction system. When in the deflated condition, the bladder is substantially contained within the base, and the headrest has a relatively narrow pre-deployment configuration. When the bladder is inflated it expands to urge the pad forward, and simultaneously expands laterally outward beyond the pre-deployment perimeter of the base to enlarge the overall width of the headrest. The headrest is relatively narrow when in the pre-deployment condition in order to minimize obstruction of the driver's rearward vision and rear seat passengers, forward vision. When inflated, the headrest expands to a relatively wide configuration to provide improved head restraint during an accident.

摘要： A method is provided for improving response time in a vehicle active tilt control system having front and rear stabilizer bars adjustable by front and rear hydraulic actuators which are movable in first and second opposing directions for adjusting vehicle body roll resistance provided by the stabilizer bars, and having a pressure control valve for controlling hydraulic pressure to the actuators. The method includes the following steps: a) operating only a single lateral accelerometer to determine the direction and magnitude of lateral acceleration during vehicle maneuvers; b) establishing the direction of movement of the front and rear hydraulic actuators in response to the determined direction of lateral acceleration; c) adjusting the pressure control valve in response to the determined magnitude of lateral acceleration; d) determining the rate of change of the magnitude of lateral acceleration as the magnitude of lateral acceleration decreases past a predetermined first threshold; and e) switching direction of movement of the front and rear hydraulic actuators in response to the determined rate of change of the magnitude of lateral acceleration, thereby anticipating directional changes in lateral acceleration to improve response time in adjusting vehicle body roll resistance during vehicle maneuvers.

摘要： A method of controlling a vehicle active tilt control system is provided for increasing the operating efficiency and improving operator/passenger comfort associated with the operation of a motor vehicle having an active tilt control system. The tilt control system includes a stabilizer bar adjustable by a hydraulic actuator which is movable in first and second opposing directions for adjusting vehicle body roll resistance provided by the stabilizer bar, and having a pressure control valve for controlling hydraulic pressure to the actuators. The method includes the following steps: a) obtaining a lateral acceleration magnitude signal; b) comparing the lateral acceleration magnitude signal to a first lateral acceleration threshold; c) enabling the active tilt control system for the vehicle when the lateral acceleration magnitude signal exceeds the first lateral acceleration threshold; d) disabling the active tilt control system for the vehicle when the lateral acceleration magnitude signal is less than the first lateral acceleration threshold; e) comparing the lateral acceleration magnitude signal to a third lateral acceleration threshold; and f) resetting the active tilt control system for the vehicle when the lateral acceleration magnitude signal is less than the third lateral acceleration threshold continuously for at least a predetermined period of time.
