Abstract: PROBLEM TO BE SOLVED: To provide a hybrid vehicle engine start control apparatus and method capable of reducing changes in driving force, due to the transmission of torque at the first explosion of an engine. SOLUTION: A target engine speed setting means is provided for setting a target engine speed that is not greater than the clutch input number of revolutions, i.e., the motor side number of revolutions of an engine clutch EC at the start of the engine. An integrated controller 6 sets a hydraulic pressure command value for the engine clutch EC, such that the actual engine speed follows the desired engine speed. COPYRIGHT: (C)2007,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide a device for control of a coolant flow rate in a rotary electric machine, capable of achieving sufficient cooling and high efficiency. SOLUTION: The device for control of the coolant flow rate in the rotary electric machine includes a flow rate control valve for changing a flow rate to be supplied into a motor and a flow rate to be flown back to a coolant reservoir out of the coolant to be scooped to the upper part in a housing, depending on a reaction force of the output torque of the rotary electric machine.

Abstract: A method for starting an engine (2) of a vehicle having a hybrid transmission (1) is provided. The hybrid transmission (1) is capable of providing motor running under a power of an electric motor (MG1, MG2) only and hybrid running under a power of both of the engine (2) and the electric motor (MG1, MG2). The power of the engine (2) is supplied to the hybrid transmission (1) by way of a clutch (3). The method includes, when the clutch (3) is engaged for starting the engine (2) during the motor running, issuing an engine start instruction when an engine speed (Ne) increases to a startable speed (Nig) with the progress of engagement of the clutch (3), and after the moment (t2) of issue of the engine start instruction, restricting increase of an engagement force of the clutch (3) and thereby suppressing the progress of engagement of the clutch (3). An apparatus for carrying out the method is also provided.
Abstract translation: 提供一种用于启动具有混合变速器（1）的车辆的发动机（2）的方法。 混合动力变速箱（1）能够仅在电动机（MG1，MG2）的动力下运行电动机，并且在发动机（2）和电动机（MG1，MG2）两者的动力下混合运行。 发动机（2）的动力通过离合器（3）供给到混合动力传动装置（1）。 该方法包括当离合器（3）在马达运行期间接合以起动发动机（2）时，当发动机转速（Ne）随着接合进展而增加到可启动速度（Nig）时发出发动机起动指令 离合器（3），并且在发动机起动指令的时刻（t2）之后，限制离合器（3）的接合力的增加，从而抑制离合器（3）的接合进行。 还提供了一种用于执行该方法的装置。
