Title: Four-wheel steering control device for vehicle
Inventor: NAKAMURA TETSUYA
IPC: B62D6/00
Filed: 1986-03-26
Abstract: PURPOSE:To improve travel safety at cornering by inputting the behavior direction from the yaw rate direction or the lateral acceleration direction and the front wheel steering direction, judging reverse steering based on inconsistency or consistency of both directions, and stopping the steering of rear wheels at reverse steering. CONSTITUTION:When a vehicle is traveling along a corner, the front wheel steering direction and the yaw rate generating direction coincide. When the vehicle exceeds the cornering limit and a driver performs reverse steering so as to maintain the vehicle attitude, the front wheel steering direction becomes opposite to the direction of the yaw rate generated on the vehicle. Therefore, the reverse steering of the driver is judged based on signals from a yaw rate sensor 5 and a steering angle sensor 3. When reverse steering is detected, rear wheel steering is stopped. Accordingly, the vehicle is set to the same condition as a vehicle steered only on the front wheels, and travel safely at cornering is improved.

Title: Controller of motor
Inventor: FUJIWARA TOSHIAKI
IPC: H02P27/02
Filed: 1984-04-05
Abstract: PURPOSE:To preferably control the initial operation of a motor by stopping a gate current of a bidirectional thyristor in the meantime until the DC voltage of a gate circuit is converged to the constant value at the transient time, thereby preventing the unstable operation. CONSTITUTION:Since a DC source in a gate circuit 1 is formed at the transient time immediately after the power source is turned ON, an unstable signal is transmitted to a transistor 2. If a DC power source voltage value in the gate circuit 1 does not arrive at the value or higher exceeding the voltage drop, the collector current of the transistor 2, i.e., the gate current of a bidirectional thyristor 4 cannot flow by a constant-voltage diode 6 connected in series with the gate terminal of the thyristor 4 at this time. Thus, a motor 3 remains stopped within the prescribed time immediately after the power source is turned ON.
