摘要： A vehicle includes a main drive unit, a sub drive unit, and a control unit. The main drive unit includes a main drive rotary electric machine. The sub drive unit includes a sub drive rotary electric machine. The control unit includes a driving force distribution ratio setting unit configured to set a driving force distribution ratio between the main driving force and the sub driving force and is configured to control the outputs of the main drive unit and the sub drive unit so that the main driving force and the sub driving force have the driving force distribution ratio set by the driving force distribution ratio setting unit. The driving force distribution ratio setting unit is configured to set the driving force distribution ratio to minimize electric power loss of the vehicle based on a vehicle speed of the vehicle and a required driving force of the vehicle.

摘要： An engine-and-electric-machine assembly, including an engine (8) and an electric machine (9). The crankshaft (7) of the engine has an extension section (7-3) that extends to the exterior of the engine, and the rotor (3) of the electric machine is mounted to the extension section. The present disclosure improves the integration level of the engine-and-electric-machine assembly, and reduces the weight and volume of the engine-and-electric-machine assembly. A vehicle driving device including the engine-and-electric-machine assembly is also disclosed.

摘要： An electric motor rotor for a hybrid module includes a rotor carrier, a piston carrier, and a tapered snap ring. The rotor carrier includes a first inner circumferential surface with an inner spline for receiving a first plurality of clutch plates, a second inner circumferential surface, radially outside of the first inner circumferential surface, a radial wall connecting the first inner circumferential surface to the second inner circumferential surface, and a groove with a conical wall. The piston carrier includes a radial outer ring installed between the groove and the radial wall. The tapered snap is ring installed in the groove and urges the piston carrier into contact with the radial wall.

摘要： A torque transfer assembly includes an engine starter, an electric machine, a torque converter, and a disconnect clutch further defined as a mechanical clutch. The vehicle includes an internal combustion engine including an output shaft, and a transmission. The engine starter is adapted to be rotatably coupled to the output shaft for rotating the output shaft to start the internal combustion engine. The electric machine is adapted to be rotatably coupled to the transmission for delivering rotational torque to the transmission. The torque converter is rotatably coupled to the electric machine and adapted to be rotatably coupled to the transmission. The mechanical clutch is adapted to be rotatably coupled to the output shaft and the torque converter. The mechanical clutch is adapted to selectively rotatably couple the output shaft to the torque converter and is adapted to selectively rotatably decouple the output shaft from the torque converter.

摘要： The invention relates to a method for starting an internal combustion engine, the exhaust gas system of which is equipped with an electrically heatable lambda sensor and a catalytic converter with an oxygen reservoir. The combination of method steps according to the invention allows the internal combustion engine to be started with an optimal raw emission reduction directly after a cold start and an optimal pollutant conversion in the warm-up phase. The invention likewise relates to a motor vehicle with an internal combustion engine comprising an exhaust gas system having an electrically heatable lambda sensor and a catalytic converter with an oxygen reservoir, and comprising a controller, wherein the controller is designed to carry out the method according to the invention.
