Title: Control device for vehicle drive system
Inventor: TOKORO SETSUO
IPC: B60W10/10
Filed: 1986-10-04
Abstract: PURPOSE:To aim at ensuring precise responsiveness, by adding a feed-forward term during abnormal operation in which the difference between a desired intake-air pipe pressure and an actually measured intake-air pipe pressure is greater than a predetermined value and to forth, in order that feed-back control is made to the opening degree of a throttle valve in accordance with the desired intake-air pipe pressure depending upon a desired torque. CONSTITUTION:A control circuit 60 carries out the map computation of a desired torque in accordance with a desired horse power and an actually measured rotational speed by an input shaft rotational speed sensor 78. Then, map computation is made to a desired intake-air pipe pressure in accordance with an actually measured engine rotational speed NE by an engine rotational speed sensor 76 and the desired torque. Further, the pressure differential P between the desired intake-air pipe pressure and an actually measured intake-air pipe pressure by a pressure sensor 72 is obtained to compute a desire feed-back amount DELTAtheta of the throttle valve opening degree. In this arrangement, during abnormal operation in such a condition that the pressure differential DELTAP exceeds a predetermined value and to forth, a feed-forward term is computed so that a precise throttle valve opening degree signal is computed in accordance with the feed-back amount DELTAtheta and the above-mentioned feed-forward term, and is delivered to an actuator.

Title: Fuel cell
Inventor: YAMAGUCHI MASANORI
IPC: H01M8/24
Filed: 1987-09-24
Abstract: PURPOSE:To easily suppress the differential pressure between electrodes by taking in or out a filler by operation from the outside in or from at least one space of a manifold and a cell container. CONSTITUTION:A pipeline and an equalizing valve 28 used to equalize the pressure of cathode has and that of nitrogen gas in a container in emergency stop are installed, and welded to a jacket wall used to store a filler 3 inside a cell container 1. As the filler 3, a liquid having high boiling point, good heat resistance, and good heat insulation is used. When the supply of a reaction gas is stopped by emergency stop, the pressure in a fuel cell is gradually decreased and the fuel cell stops its operation at last. At that time, the equalizing valve 28 is operated, and the pressure in the cell container and that of cathode gas are equalized. Since the volume in the cell container is freely adjusted, the pressure drop in the cell container is easily adjusted. Since the pressure in the cathode is adjusted to almost equal to the pressure on an anode side, the differential pressure between both electrodes and that between a reaction gas and the cell container are easily suppressed.
