Methods and systems are provided for a hybrid electric vehicle. In one example, a method may include delaying an electric-only operation of the hybrid vehicle in response to a powertrain temperature being less than a threshold powertrain temperature and an electric-only range being less than a distance between a current location and a recharging location. The electric-only operation may be initiated in response to one or more of the powertrain temperature exceeding the threshold powertrain temperature and the electric-only range being equal to the distance.

In a method for automatic movement controlling of a vehicle, at least one trajectory is determined on the basis of environmental and driving state data, and driving state quantities are subsequently calculated for an upcoming time period, using a mathematical vehicle model, taking the trajectory as a basis.

A hybrid driving apparatus is provided which enables a driver to sufficiently enjoy a driving feeling of a vehicle driven by an internal combustion engine. A hybrid driving apparatus includes an internal combustion engine that drive main driving wheels, a motive power transmission mechanism transmitting a driving force to the main driving wheels, a main driving electric motor driving the main driving wheels, an accumulator, sub-driving electric motors transmitting motive power to sub-driving wheels of the vehicle, and a control apparatus executing an electric motor traveling mode and an internal combustion engine traveling mode. The control apparatus causes the internal combustion engine to generate the driving force, the internal combustion engine is a flywheel-less engine, and the control apparatus causes the main driving electric motor to generate a torque for maintaining idling of the internal combustion engine in the internal combustion engine traveling mode.

A method is provided for controlling a hybrid drive train comprising a first partial drive train including an internal combustion engine having a crankshaft and a second partial drive train, which is separated from the first partial drive train by a torsional elasticity, having an electric machine with a rotor. A rotational characteristic value of the first partial drive train is detected via a sensor arranged on the torsional elasticity. A rotational characteristic value of the rotor is detected via a device engaged with the rotor. A quality index is determined based on the rational characteristic value of the first partial drive train and the rotational characteristic value of the rotor. The electric machine is controller to optimize the quality index.

A vehicle is operable in three modes of operation. The vehicle includes a first electromagnetic device, a second electromagnetic device electrically coupled to the first electromagnetic device, and an engine coupled to the first electromagnetic device and configured to drive the first electromagnetic device to provide electrical energy. In each of the three modes of operation, whenever the engine drives the first electromagnetic device to provide the electrical energy, the first electromagnetic device operates without providing the electrical energy to an energy storage device.

Systems and methods for operating a driveline disconnect clutch of a hybrid vehicle are presented. In one example, a driveline disconnect clutch is positioned according to whether or not there may be slip across the driveline disconnect clutch. In one example, slip may be inferred from vehicle speed and a torque converter impeller speed.

An electric drive direction confirmation system and method for a vehicle are provided. The system and method include receiving a gear selector input signal corresponding to a gear selection from an electronic gear selector on the vehicle, determining whether the gear selector input signal corresponds to a directional movement gear selection, and, when determined that the gear selector input signal corresponds to the directional movement gear selection, sending a drive command to temporarily urge the vehicle in a direction corresponding to the gear selection.

A vehicle includes a planetary gear set, a gearbox, an electric machine, and an engine. The planetary gear set has a sun gear, a carrier, and a ring gear. The gearbox is configured to transmit power from the ring gear to vehicle wheels. The electric machine is fixedly coupled to the sun gear. The engine is selectively coupled to the ring gear via a first selectable one-way clutch and selectively coupled to the carrier via a second selectable one-way clutch.

A control device of a hybrid vehicle 1, 1 comprises a driving plan generating part configured to set in advance a driving mode when the hybrid vehicle is being driven; and an output control part configured to control outputs of the internal combustion engine and the motor based on the driving mode. If the hybrid vehicle is being driven from a departure point through at least one via point to a final destination, the driving plan generating part is configured to divide a plurality of routes each having a via point as at least one of a starting point and an end point into pluralities of sections, calculate an amount of electric power chargeable to the battery while the hybrid vehicle is being driven, and set driving modes of all sections of at least one route to an EV mode based on the amount of electric power.

The disclosure includes a system and method for reconfiguring a vehicle based on one or more preferences of a first user without the first user directly providing an input to the vehicle to reconfigure the vehicle. The method may include wirelessly receiving first user profile data at a vehicle. The first user profile data may be associated with a first user. The first user profile data may describe how one or more settings of the vehicle should be configured for the first user. Upon receipt of the first user profile data, the vehicle may be configured in accordance with second user profile data describing how the one or more settings of the vehicle should be configured for a second user. The method may include reconfiguring the one or more settings of the vehicle based on the first user profile data so that the vehicle is reconfigured for the first user.
