Abstract: PURPOSE:To adequately control the damping force in response to the vibration of a vehicle by changing the damping force of a shock absorber to a larger value if the vertical acceleration of the vehicle is the preset value or less at the predetermined time when the vertical movement of the vehicle body is displaced in the neutral ground clearance direction. CONSTITUTION:Means M1, M2 detecting the vertical movement of a vehicle body and the vertical acceleration of a wheel below a spring respectively are provided. A means M3 changing the damping force of a shock absorber arranged between the vehicle body and a wheel via a command from the outside is also provided. A control means M4 is provided outputting a command to change the damping force to a larger value if the vertical acceleration detected by the means M2 is the preset value or less at the predetermined time when the vertical movement of the vehicle body detected by the means M1 is displaced in the neutral ground clearance direction. Accordingly, the damping force of the shock absorber is switched to a larger value in every half cycle in response to the cycle of the spring vibration to improve comfortableness to ride.

Abstract: PURPOSE:To make it possible to realize a desired spring motion, by successively obtaining control amounts for changing the damping force of a shock absorber from a preset pattern of displacement of the spring section of a suspension unit after the suspended section reaches its most extended and retracted positions. CONSTITUTION:The damping force may be changed by a inflow control valve 10 for controlling the amount of oil 8 flowing into a spherical gas chamber 5 in a hydraulic suspension unit 1 composed of a cylinder section 6 and disposed between a vehicle body 2 and an suspension arm 4 which follows up the vertical motion of a vehicle wheel 3. An electronic control circuit 30 control the inflow control valve 10 in accordance with output signals from an acceleration sensor 20 for detecting the vertical acceleration of the vehicle body 2 and a suspended part relative sped and displacement sensor 21. That is, a pattern of displacement of the suspended section with which the suspended section is returned to its most extended or retracted position to its neutral position, is set, and a required flow rate is obtained from the above-mentioned pattern in order to control the opening degree of the control valve f10 after the suspended section reaches its most extended position.

Abstract: PROBLEM TO BE SOLVED: To provide a system, for allowing an owner of a vehicle to permit unlocking of a door of the vehicle for the other person by a safe and simple method. SOLUTION: Registering information on the vehicle 4 is stored in a database 13 of a lock operation system 1. A password issuing part 10 generates a password, when receiving a password issuing request from an owner terminal 2, and informs the owner of the password, and stores the password in the database 13 by associatingg the password to the registering information. Afterwards, when a person knowing the password from the owner makes an unlocking request including the password from a terminal 3, a lock operation part 12 determines the justice of the unlocking request on the basis of the password, and then, sends out an unlocking signal to the vehicle 4. An electric lock device 40 of the vehicle 4 unlocks the door, when receiving the unlocking signal. COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: PURPOSE:To shorten the time from the time point at which a vehicle body vertically oscillates to the time point at which the vehicle body returns to its neutral vehicle height level, by decreasing the damping force of a shock absorber until the midway of return of the vehicle body to its neutral vehicle height level, and by increasing the damping force after the midway of the return. CONSTITUTION:A means M1 detects the vertical motion of a vehicle body. Further a means M2 changes the damping force of a shock absorber disposed between the vehicle body and the wheel in accordance with an instruction fro the outside. During a predetermined time during which the vertical motion of the vehicle body detected by the means M1 changes in the direction toward the neutral vehicle height level, a means M3 delivers a signal for changing the damping force into a large value, to the means M3. With this arrangement the damping force of the shock absorber is held at a small value until the midway of return oscillation in which the vehicle body is moved from the neutral vehicle height level and is then moved back to the neutral vehicle height level so that the oscillation of the vehicle body is rapidly settled. Meanwhile after the midway of the return, the damping force is increased to restrain the oscillation of the vehicle body.

Abstract: PROBLEM TO BE SOLVED: To eliminate the influence due to the motion of a vehicle, and to accurately measure the absolute road face shape in a road face, generally considered to have small irregularities, ups-and-downs, waviness or the like. SOLUTION: A horizontality controller controls a driving mechanism to maintain a detecting part support body 14 horizontally all the time, even if the detection part support body 14 is inclined together with a body by travel of a vehicle 12 on the measuring objective road face. The influence by the motion of the vehicle 12 is thereby eliminated, when the road face shape is measured, and the absolute road face shape is measured accurately in the road face, generally considered as having small irregularities, ups-and-downs, waviness or the like.

Abstract: PROBLEM TO BE SOLVED: To provide an apparatus or method for measuring the shape of a new road surface for travel of a vehicle.
SOLUTION: The apparatus or method for measuring the shape of the road surface measures variation of the inclined angle of the road surface or the height of the road surface using a dynamic component acting on the wheel of the vehicle. The road surface shape measuring apparatus has means A-D that, when the vehicle travels on the road surface, detects the rotation speed of the wheel and the moment (torque) of the rotation direction acting from the axle on the wheel and calculates the inclined angle of the road surface based on these values. The road surface shape measuring apparatus has a means F for calculating the variation of the height of the road surface based on the force in the longitudinal direction of the vehicle and the force in the vertical direction of the vehicle when the vehicle acting on the wheel travels.

Abstract: PURPOSE:To prevent unpleasant vibrations from continuing and improve comfortability to ride in by generating a command to change a damping force to a larger value during a predetermined period after the vertical acceleration of a vehicle body exceeds a predetermined value until the vehicle body reaches a neutral position against wheels. CONSTITUTION:An acceleration detecting means M2 detecting the vertical acceleration of a vehicle body M1 is provided, and a damping force changing means 4 to change a damping force of a shock absorber arranged between the vehicle body M1 and wheels M3 in accordance with an external command is provided. When the acceleration detected by the acceleration detecting means M2 exceeds a predetermined value, a command to change a damping force to a larger value is sent from a control means M5 to the said changing means M4 during a predetermined period after the predetermined value is exceeded until the vehicle body M1 reaches a neutral position against the wheels M3. Accordingly, if acceleration of a predetermined value or more is generated on the vehicle body M1 due to ruggedness of a road, the vehicle height is quickly returned to a predetermined neutral position.
