摘要： PROBLEM TO BE SOLVED: To quickly ensure a deceleration degree requested by a driver even when a negative pressure is insufficient during deceleration of a vehicle, in the hybrid vehicle comprising a brake booster of a negative pressure system.SOLUTION: A determination is made whether a negative pressure is insufficient based on the negative pressure (negative pressure in a brake booster 27) detected by a negative pressure sensor 32 and a decrease amount of the negative pressure during deceleration of a vehicle. When a determination is made that the negative pressure is insufficient, an EGR closing control is executed so that an opening of an EGR valve 26 is driven toward a closing direction to increase the negative pressure in an intake pipe 20. After that, a determination is made whether the negative pressure detected by the negative pressure sensor 32 is restored to a specified target negative pressure. When the negative pressure is not restored to the target negative pressure even when a specified time period has elapsed after the determination is made that the negative pressure is insufficient, an automatic brake unit 34 executes a braking-force correction control to compensate braking force of a brake 31. A shortage of the braking force of the brake 31 due to the insufficient negative pressure is compensated by the braking force of the brake 31 by the automatic brake unit 34.

摘要： PROBLEM TO BE SOLVED: To more quickly diagnose with high accuracy the presence or absence of abnormality of gear ratio control based on the condition of a pressure response member when a gear ratio is controlled by operating the condition of a frictional element, while overcoming the difficulty of rapid and accurate diagnosis.
SOLUTION: A command value of hydraulic fluid shown by a dashed line in drawing is gradually reduced when the frictional element is shifted from an engagement condition to a disengagement condition. At this time, the actual pressure is changed following the command value. Timing when the actual pressure becomes a pressure threshold β or below for shifting a pressure switch to an OFF condition corresponding to the disengagement condition is estimated based on the command value. After this timing, it is allowed to diagnose the presence or absence of abnormality of gear ratio switching control.

摘要： PROBLEM TO BE SOLVED: To prompt a driver to perform brake operation unlikely to cause insufficient negative pressure, so that fuel economy can be improved, in a hybrid vehicle having a negative-pressure type brake booster.SOLUTION: Whether or not negative pressure is insufficient is determined on the basis of negative pressure (negative pressure in a brake booster 27) and a negative pressure reduction amount detected by a negative pressure sensor 32, and if the negative pressure insufficiency is determined, EGR close control is executed which controls an opening of an EGR valve 26 to a close direction, and a driver is notified of the negative pressure insufficiency due by turning off an eco-lamp 40. Thereby, the driver notices that brake operation will cause negative pressure insufficiency, thus prompting the driver to perform brake operation unlikely to cause the negative pressure insufficiency. Consequently, a frequency of performing brake operation likely to cause negative pressure insufficiency is reduced, and a frequency of becoming negative pressure insufficiency can be reduced, so that a frequency of reduction of an energy recovery amount by deceleration regeneration of an MG 12 can be reduced by the EGR close control for securing negative pressure.
摘要翻译：要解决的问题：在具有负压型制动助力器的混合动力车辆中，提示驾驶员进行不能产生不足的负压的制动操作，从而可以提高燃油经济性。解决方案：负压是否不足基于负压（制动助力器27中的负压）和由负压传感器32检测到的负压降低量来确定，并且如果确定了负压不足，则执行EGR闭合控制，其控制开启向附近的EGR阀26通知EGR阀26，并且向驾驶员通知由于关闭节能灯40而导致的负压不足。因此，驾驶员注意到制动操作将导致负压不足，从而促使驾驶员进行制动操作不太可能导致负压不足。因此，可能导致负压不足的制动操作的频率降低，并且可以降低变为负压不足的频率，从而可以减少通过MG12的减速再生来减少能量回收量的频率通过EGR闭合控制来确保负压。

摘要： PROBLEM TO BE SOLVED: To properly control hydraulic pressure to act on an engaging side clutch of a transmission gear mechanism for an automatic transmission during engine idle stop control.SOLUTION: Pressure reducing control is executed during fuel cut of the engine by reducing hydraulic pressure to act on the engaging side clutch (a clutch LC, e.g.) of the transmission gear mechanism 15 and releasing the engaging side clutch. Pressure increasing control is executed at engine restart by increasing the hydraulic pressure to act on the engaging side clutch and engaging the half-engaged engaging side clutch. Additionally, when a rotating speed difference between a clutch output side rotating speed (a rotating speed obtained by multiplying an output side rotating speed No by the gear ratio of a first speed) and an input side rotating speed Nt reaches a predetermined value or more during the pressure reducing control, the engaging side clutch is determined to start slipping, and the hydraulic pressure at that time is learned as reference hydraulic pressure. During the pressure reducing control or the pressure increasing control, the hydraulic pressure to act on the engaging side clutch is controlled on the basis of a learned value of the reference hydraulic pressure.

摘要： PROBLEM TO BE SOLVED: To enable high precise decision of an inertia phase during control of the converter drive position of an automatic transmission and progress of control of the converter drive position at a proper timing corresponding to an inertia phase. SOLUTION: The start timing of an inertial phase is decided based on the spinning speed difference of a brake B1 switched to a release state during control of a converter drive position, and the end timing of an inertia phase is decided based on the rotation speed difference of a clutch CO. And feed back control of an oil pressure on the engagement side is executed at a timing corresponding to an inertia phase. And in case a target speed change step is renewed before starting of the inertia phase, multiple speed change control through which a target speed change step is switched to a new step at that point of time is started. Meanwhile, in case a target speed change step is renewed during the period of an inertia phase, multiple speed change control is started at that point of time, however, first only control of an oil pressure on the engagement side is started, and thereafter, at a point of time when it is decided that it is the end timing of the inertia phase, control of an oil pressure on the release side is executed.

摘要： PROBLEM TO BE SOLVED: To prevent a shock from occurring when restoring a transmission gear mechanism of an automatic transmission from a quasi-neutral state (a state of decreasing an engaging force of a clutch on an engaging side) to a normal state.
SOLUTION: When a releasing condition of the quasi-neutral state has been established during quasi-neutral control for making the transmission gear mechanism into the quasi-neutral state, restoring control is performed to restore the transmission gear mechanism from the quasi-neutral state to the normal state. In this restoring control, an oil pressure command value of the clutch on the engaging side is corrected depending on a revolution speed difference between an input shaft revolution speed Nt of the transmission gear mechanism and a target synchronous revolution speed (a revolution speed obtained by multiplying a first-stage transmission ratio by an output shaft revolution speed No of the transmission gear mechanism). As a result, even if a revolution speed difference is small between the input shaft revolution speed Nt of the transmission gear mechanism and the target synchronous revolution speed during quasi-neutral control, the input shaft revolution speed Nt of the transmission gear mechanism is allowed to gently decease during restoring control, thereby moderately proceeding to the target synchronous revolution speed.
