Presented are thermomechanical fuses for mitigating heat propagation across electrochemical devices, methods for making and methods for using such fuses, and traction battery packs with load-bearing, sacrificial thermomechanical fuses to help prevent thermal runaway conditions. A battery assembly includes an electrically insulating battery housing with multiple battery cells disposed inside the battery housing. These battery cells are electrically interconnected, in series or parallel, and stacked in side-by-side facing relation to form adjacent, mutually parallel stacks of battery cells. Thermomechanical fuses thermally connect neighboring stacks of the battery cells. Each thermomechanical fuse is formed, in whole or in part, from a dielectric material that undergoes deterioration or deformation at a predefined critical temperature; in so doing, the thermomechanical fuse thermally disconnects a first stack of cells from a neighboring second stack of cells.

A turbo lag boost compensation method is provided, including: calculate a theoretically required boost torque Ts; compare the theoretically required boost torque Ts with the maximum output torque Tpmax of a P2 motor; when Ts≥Tpmax, a required output boost torque Ts′ is equal to Tpmax; when Ts<Tpmax, the required output boost torque Ts′ is equal to Ts; determine whether a turbo lag boost timing is activated; if yes, output the required output boost torque Ts′; and if not, the boost torque is zero. Also provided are a turbo lag boost compensation apparatus, a turbo lag boost compensation device, a hybrid power vehicle, and a storage medium. The present invention effectively solves adverse effects such as a slow torque response and a sudden torque change caused by a turbo lag on an entire vehicle, and improves the drivability and power of the entire vehicle.

The present invention relates to a hybrid driving module, in which an input member is aligned in a radial direction and/or an axial direction by a rotor hub, and thus the hybrid driving module may be easily assembled and ensure the high axial balance and the operability and durability of the engine clutch. In the hybrid driving module, the input member may be aligned at least in the radial direction or in the axial direction by a central shaft extension part of the rotor hub. A bearing configured to support a rotation and thrust may be installed between the central shaft extension part and the input member. The input member may be supported to be rotatable relative to a housing. The input member may be aligned in the radial direction and/or the axial direction by the housing.

The present invention provides a hybrid driving module which fixes a rotor while hub ridges of the rotor are provided on a rotor hub and firmly provides the hub ridge to the rotor hub so as to enable vibration noise to be reduced, and which has a structure in which the hub ridges support the rotor in a state in which the hub ridges are fastened to the rotor hub at which the rotor is provided. The hybrid driving module may further include a ridge fixing structure that prevents the hub ridge from separating from the rotor hub. For example, the ridge fixing structure may be a ridge snap ring. The hybrid driving module may further include an elastic body that elastically presses the hub ridge toward the ridge snap ring. The elastic body may elastically press the rotor in the axial direction. The elastic body may also serve as a return spring of the piston plate of the engine clutch.

A gear unit includes: a stepped planetary gearset, and first and second gear shifting elements. The stepped planetary gearset has first and second sun gears, a first ring gear and a plurality of stepped planet gears rotatably mounted at a first planet carrier. The first ring gear is connected to an output shaft of the gear unit thus being fixed with respect to rotation relative to it. The first planet carrier is connected to a housing and fixed with respect to rotation relative to it. The first gear shifting element drivingly connects the second sun gear to an electric machine in a closed state, and the second gear shifting element drivingly connects the first sun gear to an electric machine in a closed state. One of the two gear shifting elements is in the closed state for driving the output shaft in rotation.

A method for controlling a powertrain of a hybrid vehicle includes the following steps performed by a hybrid controller: determining whether an ambient air temperature is lower than a predetermined temperature; driving a motor and operating a heating disc of an electrically heated catalytic converter disposed in an exhaust pipe of an internal combustion engine during a predetermined operating time when an ambient air temperature is lower than a predetermined temperature; supplying ambient air to the heating disc; and varying a flow rate of the ambient air supplied to the heating disc in response to a temperature change of the heating disc.

A hybrid vehicle includes an engine and an electric motor as driving power sources, a clutch of a hydraulic type provided between the engine and the electric motor, an electric oil pump that supplies hydraulic pressure to the clutch, a mechanical oil pump that interlocks with a rotation of the electric motor and supplies hydraulic pressure to the clutch, and a controller that controls the electric motor and the electric oil pump.

A vehicle control apparatus output a packing hydraulic-pressure command value and a cranking hydraulic-pressure command value higher than the packing hydraulic-pressure command value. The packing hydraulic-pressure command value is outputted to place a clutch in a pack-clearance-elimination completion state in a process of switching of the clutch from a released state to an engaged state. The cranking hydraulic-pressure command value is outputted, after elapse of a predetermined time required to place the clutch in the pack-clearance-elimination completion state, to cause the clutch to transmit a cranking torque required by a cranking by which a rotational speed of an engine is increased. In a case in which it is determined that a request to increase a vehicle power performance during output of the packing hydraulic-pressure command value, the cranking hydraulic-pressure command value is outputted in place of the packing hydraulic-pressure command value even before the elapse of the predetermined time.

An engine-and-electric-machine assembly includes an engine and an electric machine, a crankshaft being provided in the engine, the crankshaft including a main body and an extension section that extends out to the exterior of the engine, the extension section forming a rotation shaft of the electric machine, a rotor of the electric machine being mounted on the extension section, and a transition section being provided between the main body of the crankshaft and the extension section, wherein the rotor of the electric machine is connected to the transition section via a flange structure. By connecting the rotor of the electric machine and the crankshaft of the engine by using a flange, instead of using a key connecting structure, the strength of the connection between the rotor and the crankshaft can be improved, and optimize the moment of inertia of the transmission structure between the rotor and the crankshaft.
