A traction battery pack assembly includes, among other things, first and second pieces of an enclosure having an interior area. An attachment rim is disposed at a periphery of the first piece. The attachment rim has a stand-off that includes a platform portion and turned flange. The platform portion extends outward from the interior area in a first direction. The platform portion provides an aperture. The turned flange extends away from the platform portion in a second direction and terminates at an end face. The second direction is transverse to the first direction. The aperture is configured to receive a fastener that clamps the end face against the second piece.

An electrified vehicle includes an engine configured to selectively apply propulsive torque to wheels of a first axle of the vehicle, a first electric machine configured to selectively apply propulsive torque to the wheels of the first axle of the vehicle, a second electric machine configured to selectively apply propulsive torque to wheels of a second axle of the vehicle, a traction battery electrically coupled to the first and second electric machines, and a controller configured to control engine torque, first electric machine torque, and second electric machine torque to provide a driver demand torque at the wheels of the first and second axles. The controller allocates torque between the first and second electric machines based on associated combined losses of the first and second electric machines and maintaining the torque of the first and second electric machines in the same direction.

A vehicle driving apparatus includes: an engine; first and second rotary electric machines; a fluid transmission device including an input-side rotary element to which the engine and the first rotary electric machine are connected; and a control device configured to control an operation point of the engine by adjusting an electrical path amount in an electrical path between the first and second rotary electric machines. When a certain running mode is established, the control device is configured to correct the electrical path amount to an increased electrical path amount while maintaining an power of the engine requested by an operation of a vehicle driver, and to drive the second rotary electric machine, while controlling an output torque of the first rotary electric machine such that the electrical path amount transferred from the first rotary electric machine to the second rotary electric machine becomes the increased electrical path amount.

A battery control device includes a processor that is configured to estimate a full charge capacity of a battery based on an amount of current supplied to the battery from a start of charging to an end of charging and voltages of the battery at the start of charging and the end of charging when the battery is charged from a state where a voltage of the battery is below a predetermined start voltage threshold value to a state where the voltage exceeds a predetermined end voltage threshold value, and the battery satisfies a predetermined permission condition.

Engine combustion mode-switching transitions are controlled through a coordination control of an electric machine and a multi-combustion mode engine coupled to each other with a hybrid propulsion system by following predetermined combustion mode-switching strategies and control algorithms.

In a hybrid vehicle, each of an engine and an MG1 is mechanically coupled to a drive wheel with a planetary gear being interposed. The planetary gear and an MG2 are configured such that motive power output from the planetary gear and motive power output from the MG2 are transmitted to the drive wheel as being combined. A controller makes WGV diagnosis for diagnosing whether or not a waste gate valve is normally controllable by issuing an instruction to a WGV actuator while the controller stops combustion in the engine and controls the MG1 and the MG2 in coordination to perform motoring of the engine during traveling of the hybrid vehicle.

A lubricating device of a power transmitting system having a structural member. The lubricating device includes an oil piping assembly fixed to the structural member at a plurality of positions and having an oil passage through which a lubricant oil flows. The oil piping assembly is a resin piping assembly including a plurality of divisional components which cooperate to define a circumference of the oil passage along a length of the oil passage and which are formed of a resin material. The divisional components have respective interfacial surfaces and are bonded together with interfacial surfaces thereof being held in contact with each other. The divisional components of the resin piping assembly include a base divisional component provided with a plurality of fixing portions, and the resin piping assembly is fixed to the structural member at the plurality of positions through only the fixing portions.

A vehicular power transmitting system including a power transmitting member, an oil pump, and an oil piping assembly, and the oil piping assembly includes an oil piping body having an oil inlet and fixed, and a branch pipe. The branch pipe has a width direction parallel to a longitudinal direction of the oil piping body, and includes proximal and distal end portions. The proximal end portion is connected to the oil piping body, and the distal end portion has a delivery nozzle from which the oil is delivered toward the lubricated portion. The branch pipe has an opening formed in the proximal end portion, for communication of the branch pipe with the oil piping body, the opening having a dimension in a width direction of the branch pipe, which dimension is larger than a dimension of the distal end portion in the width direction of the branch pipe.

Methods and systems are provided for operating a driveline of a hybrid vehicle during conditions when a temperature of a motor/generator is increasing. In one example, a method is provided that adjusts engine speed as a function of motor/generator temperature while maintaining engine power output when driver demand wheel power is constant.
