A method for assignment of vehicle control includes receiving route data indicating a route between a starting location of a vehicle and a destination location, and determining an optimal vehicle configuration for the route based on a target vehicle speed and a hybrid torque split. The method further includes receiving a driver requested torque value and determining a passive pedal torque value based on the route data and vehicle powertrain data. The method further includes selectively assigning control of the vehicle to a vehicle system or to a driver of the vehicle based on the driver requested torque value and the passive pedal torque value.

A control device that may be a control device of a hybrid vehicle. The hybrid vehicle including an engine; an electric generator configured to generate electric power by operation of the engine; a battery configured to store the electric power; a traction motor configured to operate by the electric power stored in the battery; and a throttle valve configured to adjust an amount of air to be supplied to the engine. The control device is configured to estimate torque of the engine based on an output current value of the electric generator. The control device is configured to estimate an actual aperture of the throttle valve based on the estimated torque and revolution speed of the engine. The control device is configured to perform feedback control so that the aperture of the throttle valve is adjusted to the target aperture based on the estimated actual aperture.

A method of operating a first electric machine and a second electric machine in a vehicle drive includes operating the vehicle drive in a first operating mode by operating the first electric machine to regulate electrical power at a bus to maintain a first voltage on the bus and operating the second electric machine to consume electrical power from the bus. The method includes operating the vehicle drive in a second operating mode by operating the first electric machine to consume electrical power from the bus and operating the second electric machine to regulate electrical power at the bus to maintain a second voltage on the bus. A sum of the electrical power regulated by the first electric machine, the electrical power losses, and the electrical power consumed by the second electric machine is zero in the first operating mode and in the second operating mode.

A control method for a hybrid vehicle is provided. The hybrid vehicle includes: a generator configured to charge a battery by using power of an engine; an electric motor configured to drive a driving wheel by electric power of the battery; and a particulate filter configured to collect particulate matter contained in exhaust gas from the engine. In the control method, the engine is driven to raise a temperature of the particulate filter when a first temperature rise condition is satisfied in which a first predetermined amount or more of the particulate matter is accumulated in the particulate filter and the temperature of the particulate filter is equal to or lower than a predetermined temperature. Drive of the engine is prohibited, when a predetermined first condition that a driver does not intend to drive the engine is satisfied.

A vehicle includes a powerplant, a front axle having first and second wheels and a differential operably coupled to the powerplant. A power-takeoff unit (PTU) is connected to the differential. A rear axle has third and fourth wheels and a gearbox connected to the PTU without a center differential. The gearbox has a first clutch configured to selectively couple the third wheel to the PTU and a second clutch configured to selectively couple the fourth wheel to the PTU. A controller is programmed to determine, during a turn, which of the third and fourth wheels is an outer rear wheel, determine whether there is a positive or negative torque on the outer rear wheel, and disengage, or keep disengaged, the one of the first and second clutches that is associated with the outer rear wheel in response to a negative torque on the outer rear wheel.

In a vehicle drive device, a second power source is connected to a first rotating element of a differential mechanism. The other output shaft of a first output shaft and a second output shaft is connected to a third rotating element so as to be disconnectable and connectable by a disconnection-connection mechanism. A control device places the disconnection-connection mechanism in a disconnected state. When a second traveling mode in which the third rotating element is fixed to a fixing member through engagement of a first engaging element is switched to a first traveling mode in which the disconnection-connection mechanism is placed in a connected state, the control device disengages the first engaging element, executes synchronous control in which rotational speeds of the other output shaft and the third rotating element are synchronized by a second engaging element, and switches the disconnection-connection mechanism from the disconnected state to the connected state.

A vehicle control apparatus controls a vehicle-control force of a vehicle that is switchable between traveling under normal traveling control and traveling under cruise control. The apparatus includes a first target-vehicle-control-force determination unit, a second target-vehicle-control-force determination unit, and a vehicle-control-force controlling unit. The first target-vehicle-control-force determination unit determines a target vehicle-control force of the normal traveling control on the basis of an accelerator position, and switches a control mode of the normal traveling control between a normal mode and a one-pedal mode. The second target-vehicle-control-force determination unit determines a target vehicle-control force of the cruise control, and execute override when the accelerator position is greater than a reference accelerator position in the cruise control. The vehicle-control-force controlling unit controls the vehicle-control force on the basis of the target vehicle-control force determined by the first target-vehicle-control-force determination unit or the second target-vehicle-control-force determination unit.

An update process updates relationship defining data by inputting, to a predetermined update map, a state of a vehicle obtained by a state obtaining process, a value of an action variable used to operate an electronic device, and a reward corresponding to an operation of an electronic device. A range in which an operation process uses, as the action variable, a value different from a value that maximizes an expected return related to the reward is defined as a return non-maximizing range. In a case in which a degree of deterioration of the vehicle is greater than or equal to a predetermined degree, a changing process changes the return non-maximizing range to a side on which the return non-maximizing range is expanded as compared to a case in which the degree of deterioration is less than the predetermined degree.

A drive train for a vehicle includes a first electromagnetic device, a second electromagnetic device electrically coupled to the first electromagnetic device by an electrical power transmission system, and an engine coupled to the first electromagnetic device and configured to drive the first electromagnetic device to provide electrical energy. In all modes of operation where 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.
