摘要： The clutch oil pressure (PC1) supplied to a hydraulic controller of an automatic transmission is detected. If it is detected that the clutch oil pressure (PC1) is less than or equal to a first threshold value PA when a first oil pump cooperative with a drive power source is to stop, the second oil pump is driven. Therefore, after the oil pressure (for example, PY) remaining from the first oil pump has decreased, the second oil pump is driven, and an oil pressure (PX) needed for the hydraulic control of friction engagement elements is maintained. If it is detected that the clutch oil pressure (PC1) is greater than or equal to a second threshold value (PB) when the first oil pump is to be driven, the second oil pump is stopped. Therefore, the second oil pump is stopped when the oil pressure provided by the first oil pump rises to such a level that the oil pressure (PX) can be secured. Thus, the load on the second oil pump is reduced so as to allow it to be reduced in size.

摘要： In setting of an oil temperature increasing process mode, the drive control technique of the invention starts an engine to actuate a mechanical oil pump that pressure feeds a flow of lubricating oil for lubricating the mechanical parts of a transmission and other relevant parts, actuates an electric oil pump that pressure feeds the flow of lubricating oil, and makes a brake B1 included in the transmission in a semi-engagement state. A motor arranged adjacent to the transmission is then driven with lowered output efficiency. This arrangement effectively accelerates heat generation by the motor and ensures a quick temperature rise of the lubricating oil.

摘要： A driving control device for an electric vehicle includes an electric machine which is driven by a current supplied from a battery, a transmission which is coupled with the electric machine and performs shifting at a predetermined gear ratio, a charging state detecting portion which detects an electric variable that shows a charging state of the battery, a fail determination processing device which determines whether the electric variable exceeds a threshold value and makes a fail determination when the electric variable exceeds the threshold value, and a charging control processing device which decreases a rotational speed of the electric machine and reduces the electric variable when the fail determination is made. The fail determination is made to decrease the rotational speed of the electric machine when field weakening control becomes unperformable and the electric variable exceeds the threshold value, which makes it possible to prevent an overcurrent from being supplied to the battery.

摘要： A hybrid driving unit (7) in which a second electric motor (23) is disposed on the side closer to the front (the side closer to an internal combustion engine (5)) than a first electric motor (20). A casing member (14) is formed such that an inner diameter of a part thereof in which a stator (28) of the second electric motor (23) is fixed is larger than that of a part in which a stator of the first electric motor (20) is fixed. It allows the second electric motor (23) to be constructed so as to have a large radial dimension and to that extent, allows the length thereof in the longitudinal direction to be suppressed. Accordingly, it allows the length of the whole hybrid driving unit (7) to be shortened.

摘要： A hybrid drive unit includes a hybrid mechanism having at least one electric motor and a transfer that distributes driving force to front and rear wheels. The electric motor and the transfer are housed in a tubular shaped transmission case that extends in the front and rear directions of a vehicle. The hybrid drive unit is mounted on and supported by a second attachment coupled to an internal combustion engine and provided at a front end of the hybrid drive unit and a first attachment portion fixed to a vehicle body. The electric motor and the transfer that are heavy structural members of the hybrid drive unit are positioned separately to the front and rear of the first attachment portion that forms a boundary. By adopting this configuration, it is possible to reduce the amount of engine vibration that is transmitted to the vehicle body through the first attachment portion.

摘要： A drive unit for a vehicle structured so as to be able to attain an interrupting state of inertia of a drive motor under a predetermined condition. Therefore, the drive unit for a vehicle has a drive motor able to transmit driving force to a drive wheel, and an operation lever for selecting a shift range for switching the drive motor between drive and non-drive. Further, the drive unit for a vehicle has a control section having a shift position detector for detecting the shift range selected by the operation lever. The drive unit for a vehicle also has brakes for attaining a neutral state by interrupting the power transmission between the drive motor and the drive wheel when the selection of a parking range is detected by the shift position detector. Thus, a state for applying no inertia of the drive motor to a parking device, is obtained even when the parking device is operated during a slight speed running.
