摘要： PROBLEM TO BE SOLVED: To improve air bleeding characteristic by a simple structure without causing leakage of hydraulic pressure. SOLUTION: A recessed part 130 allowing an inner rotor 22 to move in the direction of the rotating axis of the inner rotor 22 is formed in a first housing 24 on the discharge ports 101, 103 side. During air bleeding, the inner rotor 22 is moved into the recessed part 130 to facilitate the movement of air from the side gap between the inner rotor 22 and a second housing 25 into a reservoir tank 71 via suction ports 102, 104. After a hydraulic oil is charged after the air bleeding, the inner rotor 22 is moved to a position away from the inside of the recessed part 130 to secure the hydraulic pressure of a pump.

摘要： PROBLEM TO BE SOLVED: To accurately and quickly decide a change of a traveling environment on a single-sided flow of a vehicle.
SOLUTION: First smoothing torque Ts1 that the history of steering torque Tt is smoothed by a short time constant and second smoothing torque Ts2 that the history is smoothed by a long time constant are calculated (step S102). When a straight traveling state on a flat road is continued, the smoothing torque Ts1 and Ts2 substantially coincide with each other and a difference |Ts1-Ts2| becomes less than prescribed amount Tα ("No" in step S103), and thereby it is decided that the vehicle continues to travel on the flat road (step S104). When the vehicle transfers to a cant road, the first smoothing torque Ts1 is immediately increased and the second smoothing torque Ts2 is gradually increased, and thereby the difference |Ts1-Ts2| gradually becomes large. When the difference |Ts1-Ts2| exceeds the prescribed amount Tα ("Yes" in step S103), it is decided that the vehicle transfers to the cant road (step S105).

摘要： PROBLEM TO BE SOLVED: To compensate slanting by a simpler technique. SOLUTION: When an operator release his/her hand from a steering wheel, yaw rate γ changes according to the magnitude of disturbance which becomes the cause of slanting, therefore, if a release state of the operator is detected ("Yes" in step S105), compensation assist torque T c is calculated according to the yaw rate γ (step S106) triggered by detection of this release state, and an electric motor 8 is drive-controlled so that this compensation assist torque T c is generated. At this time, the yaw rate γ is generated, due to disturbance, in other words, in slanting direction, therefore, the compensation assist torque T c of the opposite direction of the yaw rate γ is calculated, and the compensation assist torque T c is made larger as the yaw rate γ is larger.

摘要： PROBLEM TO BE SOLVED: To perform practical parking support by taking into consideration an area causing interference with parking.
SOLUTION: An image around one's own vehicle is picked up by cameras 2a-2d, a downward image is prepared from the picked-up image, and displayed (Step S1). When an occupant designates a parking position C and an entry-inhibited area to the displayed downward image (every determination in Steps S2, S4 and S5 is "Yes"), a track from a present position A to the parking position C for avoiding the entry-inhibited area is calculated (Step S6), and the calculated track is superpose-displayed on the downward image (Step S7). The track depicted by the projection of a vehicle body including the forward-backward changing position B and the parking position C is superposed and displayed on the downward image.
