Title: Rear wheel steering control method for four-wheel steering car
Inventor: SHIMADA HIDEO
IPC: B62D7/14
Filed: 1990-02-16
Abstract: PURPOSE:To eliminate difference in the behavior between the left and right cornerings by correcting the steering angle target value for the rear wheels, which is generated at the time of steering to the side where an actuator for steering the rear wheels is furnished, in an amount corresponding to change in the toe angle with respect to the steering angle target value for the rear wheels to be generated when steering is made to the side opposite to the above. CONSTITUTION:When the front wheels 13 are steered to the side where a motor 2 of a rear wheel steering device is located, i.e. to the left side, it is willing to steer the left and right rear wheels 9, 9 to the left so that the steering angle target value betagenerated by a control unit 12 will become beta=alpha+theta. The actually steered angle of the right rear wheel 9, however, will become alpha+theta-theta=alpha because of the change in the toe angle which is theta due to compliance steer on the basis of drop of the lateral stiffness generated on a connecting rod 8. If the front wheels 13 are steered to the right, the motor 2 steers the left and right rear wheels 9, 9 to the right so as to attain the rear wheel steering angle target value alpha to be generated by the control unit 12, and in this case no toe angle change theta will occur, and the actually steered angle of the left rear wheel will become alpha.

Abstract: PURPOSE:To save the installation space for an equipment and to easily exchange recording paper. CONSTITUTION:Since a recording paper eject tray 3 composes a part of the main body 1 of the equipment, it is not projected to an outer side. Since an original cover 6 composes the eject tray of an original 10 and an original feed tray 7 is arranged on it, the original feed tray 7 is not projected from the main body 1 of the equipment either. Also, since a recording paper cassette 2 can be pulled from the front of the main body 1 of the equipment, the replenishing operation of cut papers can be performed from the front face of the equipment and a user does not have to move around to the side part of the main body 1 of the equipment. Since the line sensors of an image read part 5 are in a pair and can read both the original of an original read surface and the original 10 on the original feed paper tray 7, the constitution can be simplified.
