摘要： A power output apparatus 110 includes a planetary gear 120 having a planetary carrier, a sun gear, and a ring gear, an engine 150 having a crankshaft 156 linked with the planetary carrier, a first motor MG1 attached to the sun gear, and a second motor MG2 attached to the ring gear. In response to an engine operation stop instruction, the power output apparatus 110 stops a fuel injection into the engine 150 and controls the first motor MG1, in order to enable a torque acting in reverse of the rotation of the crankshaft 156 to be output to the crankshaft 156 via the planetary gear 120 and a carrier shaft 127 until the revolving speed of the engine 150 becomes close to zero. This structure allows the revolving speed of the engine 150 to quickly approach to zero.

摘要： A delay time (Tset) in a normal state is set to a predetermined time Ts 1 based on an engine coolant temperature (Tw) and a state of an air conditioner switch. The predetermined time (Tsl) is determined based on a time necessary for completing preheating of an engine by a preheating device, preparations of sensors such as an air-furl ratio sensor, and warming-up of an exhaust gas purifying device (S100, S110). When it is determined that a vehicle can run using only a motor based on a required torque (Td), a required power (P*) and an SOC of the battery (S120 to S 150), the engine is started after the delay time (Tset) has elapsed. As a result, it is possible to efficiently perform start of the engine and operation immediately after the engine start, and to make control at the engine start time simple compared with when the engine is started after making determinations as to whether various preparations have been completed.

摘要： The present invention prevents a decrease in efficiency due to energy circulation in a power transmission path in a power output apparatus having an engine and a motor as power source. In the power output apparatus, a planetary gear 120 has a sun gear shaft linked with a generator MG1, a ring gear shaft linked with a motor MG2, and a planetary carrier linked with an output shaft of an engine 150. The power output apparatus carries out a control procedure to avoid energy circulation, which goes through the planetary gear 120, the motor MG2, and generator MG1, and the planetary gear 120, and thereby prevent a decrease in efficiency. The energy circulation occurs when the motor MG2 converts the power output from the engine 150 to electric power and the generator MG1 carries out power operation with the regenerated electric power. The control procedure monitors a torque command value of the motor MG2 and shifts a driving point of the engine 150 to another driving point of higher revolving speed when the torque command value is not greater than a threshold value Tref.

摘要： The control technique of the invention sets smaller values to an engine stop reference value and an engine start reference value in the state of use of a regular fuel, compared with values in the ordinal state. When a calculated engine power demand Pe* is less than the engine stop reference value, the control stops the operation of the engine. When the calculated engine power demand Pe* exceeds the engine start reference value, on the other hand, the control starts the operation of the engine. This arrangement facilitates the start of the engine in the state of use of the regular fuel, compared with the start in the ordinary state. A corrective revolution speed ”N is added to a target revolution speed Ne* of the engine, in order to respond to a decrease in output power from the internal combustion engine.

摘要： When a starter switch is switched from OFF to ON, a hybrid ECU determines that a driver intends to start driving a vehicle (S110), reads a temperature of each of items (coolant inside an engine, injectors, lubricating oil, and the like) (S120), and makes a determination on the necessity of preheating depending on whether or not each of the items has reached a corresponding one of suitable temperature ranges (S130). If preheating is required, the hybrid ECU sets an engine start permission flag F as "0" so as to prohibit the engine from being started (S140), instructs an engine ECU to preheat the item requiring preheating (S150), and terminates a program. On the other hand, in making a determination in S130 on the necessity of preheating depending on whether or not each of the items has reached a corresponding one of the suitable temperature ranges, if every one of the items has reached a corresponding one of the suitable temperature ranges, the hybrid ECU determines that preheating is not required, sets the engine start permission flag F as "1" so as to permit the starting of the engine (S160), and terminates the program.

摘要： When a first motor MG1 cranks and starts an engine 150 that is in the cold, the revolving speed of the engine does not increase quickly 150. It is accordingly required to control the first motor MG1, in order to prevent electric power 194 stored in a battery from being wasted. A starting control apparatus does not cause the first motor MG1 to output a torque corresponding to a difference between a target revolving speed N* and an actual revolving speed Ne of the engine 150, but gradually increases a target torque STG by the open-loop control and restricts the magnitude of the target torque STG to a preset maximum torque STGMAX, which depends upon a cooling water temperature Tw of the engine 150. When the engine 150 is in the cold, the high viscosity of lubricant causes the revolving speed of the engine 150 not to quickly increase in response to the high target torque set to the first motor MG1. In this case, the maximum of the target torque is restricted to a smaller value, so as to prevent the electric power stored in the battery 194 from being wasted. The injection allowable revolving speed, at which the fuel injection to the engine 150 is allowed to start, is also set equal to a small value. This causes the engine 150 to start self driving at an earlier timing, thereby saving the electric power consumed by the first motor MG1.

In response to an engine operation stop instruction, the power output apparatus 110 stops a fuel injection into the engine 150 and controls the first motor MG1, in order to enable a torque acting in reverse of the rotation of the crankshaft 156 to be output to the crankshaft 156 via the planetary gear 120 and a carrier shaft 127 until the revolving speed of the engine 150 becomes close to zero. This structure allows the revolving speed of the engine 150 to quickly approach to zero.
