Abstract: PROBLEM TO BE SOLVED: To easily retreat a vehicle to a desired position by retreating while steering so as to coincide with the expected locus of an eye mark with the target point of a parking space, and making the operating angle of a handle to maximum and retreating when the eye mark is coincided with the target point of the parking space. SOLUTION: Fixed guide display 20 and the expected locus 25 of an eye mark 24 are displayed on the image plane 29 of a monitor so as to superpose on the image of a camera. Then a vehicle is gradually retreated while steering a handle so as to coincide the expected locus 25 of the eye mark 24 with the corner 28 of a parking space 27. When the eye mark 24 is coincided with the corner 28 of the parking space 27 and superposed, the operating angle of the handle is made maximum in the reverse direction to beginning parking in longitudinal row, and it is retreated as it is. Further when one side line of a fixed guide display becomes in parallel with the road side, the handle is returned into a rectilinear condition to complete longitudinal row parking. Handle operation at retreating containing longitudinal row parking can be assisted.

IPC: F02M25/07
Filed: 1981-08-12
Abstract: PURPOSE:To prevent deterioration in the performance of an internal combustion engine, by reducing error in the control of EGR (exhaust-gas recirculation) ratio by switching feedback control of the EGR ratio substantially to open-loop control in the operational range of engine where the amount of recirculated exhaust gas is small. CONSTITUTION:An EGR control circuit 12 controls the openings of a throttle valve 6 and an EGR valve 7 in response to the output signals of an engine load sensor 17 and a engine speed sensor 18, so as to obtain a prescribed EGR ratio  suited for the operational conditions of engine. Further, in order to correct the EGR ratio, output signals of a sensor 21 for detecting the temperature of recirculated exhaust gas and a sensor 22 for detecting the temperature of mixture gas are also furnished to the control circuit 12. The control circuit 12 effects feedback control on the EGR ratio on the basis of these signals. Here, arrangement is such that control of the EGR ratio is switched from feedback control to open-loop control in the operational range of engine where the error in measurement of the EGR ratio tends to increase, i.e., where the opening of the EGR valve 7 is small, so as to reduce the error in control of the EGR ratio.

Filed: 1979-09-29
Abstract: PURPOSE: To make the function of the tension-monitoring thickness controller to effectively work, and to perform the thickness control in good accuracy, by making the output of the controller to always stay in the limit of the limiter.  
     CONSTITUTION: If the thickness deviation on the run-out side of the final stand is positive, the output of the controller 9 changes according to the output of the thickness detector 8, and the controller 9 works to slow down the speed of the roll 3 of the final stand. If the output of the controller 9 increases and reaches the level of the upper limit set in the relay 11, the relay 11 is actuated to close the contact 12, and the control unit 13 produces a command to reduce the rotational speed of the roll of the first stand. Hereby, the tension is increased between the first and the second stands, and the thickness is reduced on the run-out side of the second stand. As a result, the thickness on the run-out side of the final stand is reduced. Then, the  output of the controller 9 begins to decrease, so that the control can be performed  without reaching the limit point of the limiter 10, and the function of the control  block, that is the tension-monitoring thickness controller, is fully developed.
