Abstract: An operation mode of a secondary battery (BAT) is determined based on state of charge of BAT. A power generation provisional command value of fuel cell (FC) at time i is determined to maximize efficiency of FC based on system required power and state of charge of BAT at time i. An intermittent ON/OFF state at time i is determined such that switching of intermittent operation of FC is not continuous based on operation mode of BAT, the power generation provisional command value, and the system required power at time i, and an intermittent ON/OFF state at time (i?1). Further, when intermittent ON is determined at time i, the FC is stopped, and when intermittent OFF is determined at time i, a larger one is output, as the power generation command value for the FC at time i, between the power generation provisional command value and an intermittent OFF threshold.

Abstract: An exhaust gas control apparatus includes a control device controlling a urea addition valve for adding urea from an upstream side of a NOx reduction catalyst. The control device obtains an ammonia adsorption amount distribution through the NOx reduction catalyst. When an ammonia adsorption amount in a predetermined part on a downstream side equals or exceeds a predetermined threshold, the control device controls the urea addition valve to stop the urea supply or reduce the amount thereof. The urea addition valve is controlled based on an adsorption amount distribution obtained from a model on which the catalyst is divided into cells such that an ammonia adsorption amount in a first cell positioned furthest upstream equals or exceeds a predetermined threshold close to a saturation adsorption amount and an ammonia adsorption amount in a second cell positioned downstream of the first cell reaches a predetermined target value smaller than the threshold.

Abstract: A control apparatus and method control a torque of an engine coupled to an input shaft of an automatic transmission during a shift by that automatic transmission. A torque-down control by which the engine torque is decreased by a predetermined amount is performed, a torque-restore control starting point at which time torque-restore control is to be started is determined, and the torque-restore control so as to gradually restore the engine torque to a value before the torque-down control was performed is started at the torque-restore control starting point. The torque-restore control starting point is determined according to a dynamic model which simulates behavior of the automatic transmission over time from start of the torque-down control, so that a rotational speed of the input shaft of the automatic transmission at a target point substantially matches a target speed.

Abstract: The load element state detecting portion 72 detects the completion of the filling of the hydraulic oil into the clutch 62 and the working limit of the accumulator 64 on the basis of the displacement of the spool valve element 42. That is, since the completion of the filling of the hydraulic oil into the clutch and the working limit of the accumulator 64 are directly detected, so that the completion of the filling of the hydraulic oil into the clutch 62 and the working limit of the accumulator 64 can be detected with high precision regardless of differences among products and the time-lapse variation. Furthermore, they can be detected without equipping any special device to the hydraulic control circuit, and thus there is an advantage that the device construction is simple.

Abstract: In order to control slip amount of a disengagement side engagement device at the time of a gear shift operation, a target value Nr for rotational speed of an input shaft of an automatic transmission is calculated inside an input shaft speed target value calculating block. Slip control of the disengagement side engagement device is then carried out by controlling engine torque using an engine torque control amount obtained from a engine torque control amount estimation block and the clutch slip amount compensation value calculating section to cause rotation speed Nt of the input shaft to follow the target value Nr. In this way, responsiveness and precision of slip control of the disengagement side engagement device at the time of gear shift operation are improved, and it is possible to improve gear shift shock and to carry out a gear shift operation in a short period of time.
