摘要： A power steering system is disclosed which automatically corrects unexpected variations in the path of a vehicle without requiring a driver to make corrections. A rotary valve in the power steering system includes an inner sleeve connected to a steering wheel, an outer sleeve connected to a pinion shaft meshed with a rack bar, and a torsion bar coupled to the inner sleeve and the pinion shaft. The rotary valve switches oil passages communicating with a power cylinder by means of relative rotation between the inner sleeve and the outer sleeve to thereby assist in steering. The outer sleeve and the pinion shaft are connected to each other for slight relative rotation through an elastomer or resilient connecting member. If an unexpected variation in path is produced in the vehicle, the outer sleeve is rotated by the operation of a torque motor which causes the operation of the rotary valve, thereby moving the power cylinder whereby a steering force is produced for correcting the variation in path.

摘要： In a first type, there is provided, inside an inner tube of a twin-tube type of damper, a pressurizing chamber to be defined by a free piston which is slidably fit onto an outer surface of a rod. A fluid pressure from an outside pressure source is supplied to the pressurizing chamber to push down a damper piston via the free piston to thereby forcibly contract the damper. In a second type, there is provided inside an inner tube a cylinder which is slidably fit onto an outer surface of a rod, and a piston mounted on the rod is inserted into the cylinder. A fluid pressure from the pressure source is supplied to the pressurizing chamber inside the cylinder to push down the rod via the piston to thereby forcibly contract the damper. In a third type, a rod is slidably inserted into a partition wall in an intermediate portion of a damper main body of a mono-tube type of damper. A free piston which is prevented by a stopper member from dropping out of position downwards is slidably mounted onto an outer surface of a rod portion below the partition wall. A fluid pressure from a pressure source is supplied to a pressurizing chamber to be defined between the partition wall and the free piston. The rod is pushed down via the free piston and the stopper member to thereby forcibly contract the damper.

摘要： An image of a road area ahead of a vehicle is formed based on road data read from a navigation system, or based on an image shot by a camera means such as a video camera. A temperature profile ahead of the vehicle detected by a temperature detecting means such as an infrared camera is superposed on the image of the road area. As a result, if a low-temperature zone is detected on the road area, it is determined that there is snow or ice existing on the road area, or if a high-temperature zone is detected, it is determined that there is a person or animal existing on the road area, thereby informing a driver by an alarm means or a display means to avoid such an obstruction or hazard. Thus, it is possible to perceive snow, ice, a person and an animal existing on a road ahead of the vehicle without relying on a driver's visual judgment, and to give an alarm so that the driver may timely take an appropriate countermeasure to avoid the obstruction or hazardous situation.

摘要： A course travel judging device judges based on outputs from a map information outputting device and a subject vehicle position outputting device whether a subject vehicle is traveling on a course set by a course setting device. If the subject vehicle is traveling on the set course, a vehicle speed is controlled by a travel control device, so that the subject vehicle can safely pass through a curve ahead thereof. If the subject vehicle has deviated from the set course, an alarm is given to an occupant by an alarm device, and the control of vehicle speed by the travel control device is stopped. If a departing possibility judging device judges that there is a possibility of departing of the subject vehicle from the set course, a deviatable course is set by a deviatable course determining device, and the vehicle speed is controlled by the travel control device, so that the subject vehicle can safely pass through a curve having a severest passing condition on either of the set course or the deviatable course. Therefore, even if a vehicle has deviated from a course determined through a navigation system, an appropriate control of vehicle speed can be carried out.

摘要： A road surface condition-detecting system for a vehicle detects a road surface condition from road noise generated by a vehicle wheel. The road surface condition is determined based on parameter data of frequency components of the road noise, by a neural network. The road noise may be corrected by eliminating therefrom a disturbance, such as audio output and exhaust noise. A present state of the road surface condition may be determined based on at least two consecutive determinations made based on the road noise detected at regular time intervals. Exclusive neural networks may be used for respective road surface condition types. One of a plurality of neural networks provided for respective vehicle speed ranges may be selected according to an actual vehicle speed. Detected sound pressure levels of the road noise extracted by frequency analysis may be normalized within respective ranges defined by upper and lower limits set corresponding to predetermined frequency ranges before being supplied to the neural network.

摘要： The hydraulic pressure to be supplied to a hydraulic actuator mounted on a vehicle, such as a hydraulic cylinder for vehicle height control, is arranged to be generated by utilizing a waste heat of a power source such as an engine of the vehicle or the like. There are provided an oil chamber to be connected to a hydraulic actuator, a pressurizing chamber containing therein, in a sealed manner, a medium which varies between a gaseous state and a liquid state, and a heating device which heats and evaporates the medium inside the pressurizing chamber and through which cooling water for cooling the power source to be mounted on the vehicle flows. The hydraulic pressure is generated by compressing the oil chamber by a vapor pressure of the medium inside the pressurizing chamber. In case the hydraulic actuator is a hydraulic cylinder for a vehicle height control, there is provided a flow control valve which controls the amount of supply of the cooling water to the heating device depending on the vehicle height.

摘要： A steering angle of rear wheels are steered according to a deviation between an ideal yaw rate response and an actual yaw rate response to the given steering wheel input. By combining feedback control and feed forward control, immunity from external disturbances and lateral stability can be both ensured each at a high level over the entire range of vehicle speed. By appropriately selecting the transfer function of the control system, it is possible to achieve desired responsiveness and stability. Furthermore, the vehicle response in the range where the cornering force of tires tends to saturate can be improved, and it is therefore possible to neutralize the steering property over the entire vehicle speed range.

摘要： An automatic travelling apparatus which is capable of finding out a permissible travelling area from images taken by an image pick-up device to set a target course in the permissible travelling area; determining a steering amount appropriate for the purpose of permitting the vehicle to put itself on the target course, in consideration of the instantaneous travelling condition of the vehicle; and performing the exact steering control in terms of the steering amount. The exact travelling attained by the automatic travelling apparatus according to the present invention is attributable to a two-step determination in which first, a target course is set in a permissible area, and a tentative course is set appropriate for the purpose of permitting the vehicle to put itself on the target course.
