Abstract: A problem to be solved by the present invention is to provide an adhesive tape capable of maintaining excellent adhesive strength for a long time even when sweat, sebum, an alcohol, or the like adheres thereto. The present invention relates to an adhesive tape having an adhesive layer containing an acrylic adhesive, the acrylic adhesive including an acrylic copolymer, in which the acrylic copolymer contains, as constituent components, (A) 5 to 20% by mass of a carboxyl group-containing monomer, (B) 0.01 to 1% by mass of a hydroxyl group-containing monomer, and (C) one or two or more selected from the group consisting of other alkyl (meth)acrylate monomers and alicyclic monomers, in which the average number of carbon atoms of saturated hydrocarbon groups included in the monomers (C) is 4 or less.

Abstract: Provided is a control system that assists the vehicle operator in avoiding an obstacle by making use of simple information on the surrounding environment, and the effectiveness of such a system was demonstrated by computer simulations. The lateral acceleration that would enable the vehicle to avoid an obstacle is converted into a target yaw rate, and this contributed to the improvement in the property of a man—vehicle system in avoiding an obstacle. The target yaw rate can be relatively easily achieved by controlling the fore-and-aft forces of the tires. In particular, by including a phase advance in the target yaw rate, the responsiveness of the evading motion can be increased and the stability of the vehicle can be improved at the same time.

Abstract: In a vehicle operation assist control system for assisting a vehicle operator to operate a vehicle, a distance to the obstacle and a width of the obstacle are detected by a radar or the like, and, when an obstacle is detected, the system determines an evasion path and accordingly modifies the map information available to the system. Therefore, the system, being aware of the situation, would not interfere with the vehicle operator taking an evasive action. The evasive path may be defined as a curvature which changes as a sinusoidal mathematical function of the position of the vehicle along the path. The control system may be based on a yaw rate control or a vehicle side slip angle control.

Abstract: The favorable responsiveness and the stability of a vehicle is sought to be achieved even under extreme traveling conditions. A yawing moment which a vehicle is desired to produce is computed according to a dynamic state quantity of the vehicle such as the vehicle speed and the cornering force of each of the wheels, and a braking force or a traction which is applied to each of the wheels is individually controlled so as to achieve the computed yawing moment. Therefore, even under conditions where the gripping force of the tires is close to a limit, it is possible to improve the responsiveness and stability of the behavior of the vehicle. Further, by using the sliding mode control, it is possible to improve the stability and the robustness of the control system.

Abstract: In driving a motor vehicle in accordance with a control plan, the influence of the inclination of a road is recognized so as to realize an accurate control. The position and speed of a vehicle after a predetermined time period as estimated on the basis of the detection of magnetic nails, are estimated by a first processing portion, while the control plan of the vehicle (the correlation between the position and speed of the vehicle) is determined by a control plan processing portion on the basis of information received from a leakage coaxial cable. The deviations between the control plan and the estimated position and speed of the vehicle are calculated, and these deviations are further multiplied by gains Kx and Ku in a control plan converting portion so as to calculate a target acceleration. A throttle and a brake are controlled on the basis of the target acceleration, whereby the vehicle is driven in conformity with the controls.

Abstract: Provided are a method and system for computing a vehicle body slip angle in the vehicle movement control so as to allow the vehicle movement to be controlled with an adequate response and stability for practical purposes even without directly detecting or accurately estimating the frictional coefficient between the road surface and the tire. A tire slip angle is computed from a yaw rate, a vehicle speed, a vehicle body slip angle and a road wheel steering angle; a cornering force is computed from a dynamic model of the tire by taking into account at least the tire slip angle; and a hypothetical vehicle body slip angle is computed from the cornering force, the vehicle speed and the yaw rate; the tire slip angle being computed by feeding back the hypothetical vehicle body slip angle in a recursive manner.

Each of the following motor vehicles controls itself to run in platoon based on the transmitted motion information.

Abstract: An automatically driven motor vehicle automatically runs on a running path having path markers while detecting the path markers with a marker sensor. A present position of the motor vehicle on the running path is recognized, and a speed plan which governs a position and a speed of the motor vehicle on the running path is generated. A planned position to be reached by the motor vehicle after a predetermined time and a planned speed of the motor vehicle at the planned position are determined from the present position of the motor vehicle based on the speed plan. A predicted position to be reached by the motor vehicle after the predetermined time and a predicted speed of the motor vehicle at the planned position are determined from the present position, speed, and acceleration of the motor vehicle. A distance deviation between the predicted position and the predicted position and a speed deviation between the planned speed and the predicted speed are determined.

Abstract: In the control of legged mobile robot, a desired walking pattern (gait) is usually preestablished supposing a floor such that the robot walks on the floor. However, if a floor on which the robot walks actually is not the same as the supposed floor so that there is an angular therebetween, floor reaction force is not the same as that desired, causing the locomotion stable. Therefore, the error is estimated and the desired walking pattern is corrected in response to the error such that the floor reaction force becomes as desired. Namely, the robot's possible floor contact portion's position is firstly calculated on the assumption that the robot does not exhibit any compliance behavior including mechanical deformation intrinsically assigned thereto and a plane which wholly or partly includes or has the possible floor contact portion's position, is presumed. Then an angle formed by the virtual plane and the supposed floor is presumed.

Abstract: A heads-up display system for a road vehicle, comprising sensors for detecting the motion related parameters of the vehicle, computer for predicting the motion of the vehicle, and a heads-up display for displaying information within the view of the driver of the vehicle. The computer converts the predicted motion of the vehicle into an image display on the heads-up display so as to permit the driver to see the image display in a certain relationship with his view as he looks ahead of the vehicle. Thus, the driver can gain useful information on the motion of the vehicle such as limit turning trajectories and braking distances so that he can operate the vehicle more easily and more sensibly than was possible heretofore. The heads-up display preferably comprises a projector for projecting an image display on the windshield of the vehicle.
