Abstract: The present invention relates to the shared vehicle port for automatically parking and delivering a shared vehicle used by a plurality of users, comprising: an automatic driving area having a passenger loading area and a passenger unloading area separated from each other and being connected to a vehicle passage via the passenger loading area and the passenger unloading area; and a user waiting area adjacent to the vehicle passage, the passenger loading area, and the passenger unloading area.

Abstract: When a user enters a destination using a touch panel display unit, a system control unit calculates a predicted travel distance from a present position to the destination, determines an electric vehicle having a remaining battery capacity required to travel the calculated predicted travel distance, and supplies the determined electric vehicle to the user.

Abstract: An automatic steering control apparatus automatically steers a motor vehicle to run along a predetermined running path having path markers. The path markers are detected with a marker sensor on the motor vehicle, and positional relationships between a present position of the motor vehicle and the running path are successively determined based on a detected output signal from the marker sensor. Positions of the motor vehicle on map data stored on the motor vehicle are successively determined based on the positional relationships and the map data. Curvature information of portions of the running path on the map data is attained through communications with a travel information providing facility disposed outside of the motor vehicle, and curvature information of the running path ahead of the recognized present position of the motor vehicle is acquired based on the curvature information attained through communications with the travel information providing facility.

Abstract: Disclosed is an automatic travelling apparatus which is capable of taking an image of an area ahead of a vehicle in its running direction by an image pick-up device fixed to the vehicle; determining, by processing the taken image, a permissible travel path in a X-Y coordinates having the Y-Axis corresponding to the axis of the vehicle's running direction; setting a target course in the determined permissible travel path; estimating a steering amount necessary for permitting the vehicle to follow the target course on the basis of the detected running condition of the vehicle; and steering the vehicle to follow the target course with reference to the steering amount; and also is capable of determining a side-slip angle of the vehicle and turning any one of patterns--image, permissible travel path and the target course--by the determined side-slip angle to coincide the actual running direction of the vehicle with the direction of the Y-axis.

Abstract: A steering system for a motor vehicle having power steering means including an actuator for turning steerable road wheels of the motor vehicle includes a control mechanism for eliminating a deviation between a desired direction of travel of the motor vehicle and an actual direction of travel of the motor vehicle, based on an output signal from a direction indicating mechanism which indicates the desired direction and an output signal from a direction detecting mechanism which detects the actual direction. The control mechanism determines a target turning angle for the steerable road wheels dependent on the deviation between the desired direction and the actual direction, and controls the power steering mechanism to turn the steerable road wheels up to the target turning angle.

Abstract: The method of the present invention improves the damping property of the yaw motion of the vehicle by feeding back a detected yaw rate value in a dynamic sense for compensating the front wheel steer angle so as to increase the damping coefficient of the yaw motion of the vehicle. By controlling the front wheel steer angle by accounting for not only the proportional term of the steering wheel input angle but also the derivative term which is proportional to the steering wheel input angular speed, in the feed-forward control of the front wheel steer angle in relation with the steering operation by the driver, and by appropriately varying the control parameters of the yaw rate feed-back and the steering wheel input feed-forward, the yaw response of the vehicle can be made proportional to the steering wheel input, and the response delay in the yaw rate against the steering wheel input can be reduced to substantially zero.

Abstract: A control unit used for antilock brake systems, which comprises a support base having a hydraulic channel, an oil tank, and an electro-magnetic valve provided with openings communicating with the hydraulic channel and the oil tank, the valve being supported on the support base and in turn supporting the oil tank. The control unit is characterized in that a support hole and a connecting wall covering the support hole are formed in the bottom wall of the oil tank, the support hole is oil-tightly fitted around the upper end section of electro-magnetic valve and the connecting wall is connected by a screw to a shaft projected from the upper end face of the electro-magnetic valve, and that in the connecting wall is provided a through hole for communicating the inside of the oil tank to the electro-magnetic valve.

Abstract: A material for destroying concrete structures, rock formations and the like comprises a mixture of 20 to 80 parts by weight of coarse-grained quicklime adjusted to a particle size of from 88 to 3000 microns, and 20 to 80 parts by weight of cement. The cement may contain calcium sulfoaluminate as a hydraulic component, and a retardant may be added to the mixture to retard the hydration of the calcium sulfoaluminate. The material is blended with water and then injected into holes formed in the body to be destroyed, the material expanding as it hydrates to crack and fracture the body.
