摘要： A strainer has an inlet for oil; a filter through which the oil that has flowed in from the inlet passes from inside to outside; a first supply port for supplying, to a first oil pump, the oil that has passed through the filter; a second supply port for supplying, to an intermittently driven second oil pump, the oil that has passed through the filter. The second supply port is located more upward than the first supply port; and the filter has a region located below the second supply port.

摘要： A control device and method controls a vehicle having an internal combustion engine connected to an automatic transmission via a torque converter with a lockup device. The torque of the internal combustion engine is limited the by a torque limit value based on a speed difference between an input rotational speed and an output rotational speed of the torque converter during acceleration in a non-lockup state. The torque-limiting of the internal combustion engine is prohibited torque-limiting upon a prescribed condition being met. The prescribed condition is met by a heating request, during hill climbing/towing, during travel at high vehicle speeds, when the accelerator pedal opening angle exceeds or is equal to a prescribed opening angle, when the torque limit value is greater than a target torque, in a range other than a D range, or in a mode other than normal mode.
