摘要:
A control device is provided for a hybrid vehicle power transmitting apparatus wherein when a fuel type supplied to an engine is altered, a drop in startability of the engine resulting from alteration on the fuel type is suppressed. Fuel-type determining means determines the fuel type for use in operating the engine, based on which a reactive control representing a control of reactive control of a second electric motor counteracting rotational resistance of the engine during engine startup, is altered. Accordingly, second-motor torque (reactive torque) for increasing an engine rotation speed during engine startup is adjusted depending on the fuel type, thereby increasing a temperature of fuel compressed and expanded in the engine, to a level available to initiate an ignition. This prevents the alteration of the fuel type from causing degradation in startability of the engine when the fuel type supplied to the engine is altered.

A vehicle control device includes a drive source control unit configured to control a drive source on the basis of a creep drive force set so that a vehicle does not slip down when being stopped on a gradient road and a braking force calculation unit configured to calculate a braking force generated on the basis of a braking operation of a driver. The drive source control unit reduces a drive force generated by the drive source when the braking force is larger than the creep drive force when the vehicle is stopped.

A motor control apparatus including a motor 1, a transmission 5 disposed adjacent to the motor 1 or in the vicinity of the motor 1, an oil temperature sensor 5 that detects temperature of lubricating oil of the transmission 5, a cooling mechanism that cools a motor with a refrigerant, a refrigerant sensor that detects temperature of the refrigerant, and a controller that controls torque of the motor 1. Further, the controller selects either the lubricating oil temperature detected by the oil temperature sensor 5 or the refrigerant temperature detected by the refrigerant sensor as detected temperature and applies limitation to torque based on the detected temperature.

A thermal management system is provided that allows efficient thermal communication between a refrigerant-based control circuit and a pair of non-refrigerant-based control circuits, where one of the non-refrigerant-based control circuits is thermally coupled to the vehicle's battery system and the other of the non-refrigerant-based control circuits is thermally coupled to the vehicle's drive train. The refrigerant-based control circuit may be operated either in a heating mode or a cooling mode and is coupled to the vehicle's HVAC system using a refrigerant-air heat exchanger, and to one of the non-refrigerant-based control circuits using a refrigerant-fluid heat exchanger. Multiple diverter valves allow the three thermal control circuits to be arranged in any of a variety of configurations, and to be coupled to any of a variety of radiators, thus allowing the system to efficiently regulate the temperature of the passenger cabin, the battery system and the drive train.

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:
An object oil temperature Toil* is determined by adopting a gradual change process for an oil temperature Toil of a cooling lubricant oil, which is used to lubricate and cool down a motor and a transmission constructed to cause an output power of the motor to be subjected to speed change and to be transmitted to a driveshaft (step S180). A load factor R2 of the motor MG2 is subsequently set based on the set object oil temperature Toil* and a motor coil temperature Tcoil2 (step S190). A motor torque command Tm2* is set with the load factor R2 (step S200), and the motor is then driven and controlled to ensure output of a torque equivalent to the set motor torque command Tm2*. This arrangement drives and controls the motor with consideration of the oil temperature Toil of the cooling lubricant oil and thus ensures more adequate actuation of the motor, compared with a conventional drive control without consideration of the oil temperature Toil of the cooling lubricant oil.

When an engine is in operation an ignition switch is turned off by a driver an ECU executes a program including the step of actuating an electric motor driven oil pump.
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.
