摘要： Provided is a control device for a vehicle including a continuously variable transmission. The control device includes a lock-up clutch, an oil pump, an electric motor, and a device control unit. The lock-up clutch is disposed in a torque converter coupled to the engine and switchable between an engaged state and a released state. The oil pump is driven by the engine and supplies a hydraulic oil to the continuously variable transmission. The electric motor is coupled to the engine and controlled to be in a powering state in which the engine is rotationally driven. The device control unit controls the lock-up clutch to put into the released state and controls the electric motor to put into the powering state if a discharge pressure of the oil pump falls below a threshold value at the time of a vehicle deceleration in which a fuel supply to the engine is cut off.

摘要： A diagnostic device diagnoses a hydraulic pressure control actuator which drives a line pressure control valve to regulate a pressure of hydraulic oil between upper and lower limit line pressures, so that the pressure approaches a predetermined target line pressure. The diagnostic device includes: an actual hydraulic pressure detection unit to detect an actual hydraulic pressure; a determination value setting unit to set a high pressure fixation determination value which is increased as the driving revolution rate is increased so as to substantially match a characteristic of the actuator at a time of high pressure fixation; and a fixation determination unit to determine high pressure fixation of the actuator when the actual hydraulic pressure substantially matches the high pressure fixation determination value with a difference between the target line pressure and the upper limit line pressure not lower than a predetermined value.

摘要： Provided is a range switching device for performing switching among drive, reverse, and neutral ranges of a transmission. The device includes a first switching valve driven by a first actuator and a second switching valve driven by a second actuator. The valves switch an oil channel to transmit the oil pressure from an oil pressure supply source between first state and second states. When the first and second switching valves are in the first and second states respectively, the oil pressure is transmitted to the forward fastening element. When the first and second switching valves are in the second state and first states respectively, the oil pressure is transmitted to the reverse fastening element. When both the valves are in the first or second state, oil pressure transmission to the forward and reverse fastening elements is substantially blocked.

摘要： [Object] To provide a shift control device that, in a shift control device of a vehicle equipped with an idling-stop mechanism and a shift-by-wire mechanism, is capable of preventing setting off at a timing that the driver does not expect when returning from an idling-stop state.[Solution] The SBW-CU (40) that constitutes the shift control device (1), in the case of selection information for selecting the R range being output during an idling stop, switches the shift range of the automatic transmission (10) to the R range when the vehicle is braked, and switches the shift range to the N range or the P range when the vehicle is not braked and the shift range of the automatic transmission (10) is the D range. Also, the SBW-CU (40), in the case of selection information for selecting the R range being output during an idling stop, maintains the shift range without switching it when the vehicle is braked and the shift range of the automatic transmission (10) is other than the D range.

The third and fourth switching valve cooperatively control the transmission of the oil pressure from the second control valve to the forward or reverse driving element (R). The third and fourth switching valves each perform a substantially same oil pressure transmission when the state of the second and third actuators is reversed with respect to the first switching and second switching valves, respectively.
