A hybrid vehicle includes an engine, an electric machine, a traction battery electrically connected to the electric machine, and a controller. The controller is programmed to, in response to the vehicle approaching a decline, overrepresent a state of charge (SOC) of the traction battery to cause a torque command to the engine to decrease and a torque command to the electric machine to increase such that discharge of the traction battery increases in advance of the decline.

A vehicle control device includes at least one ECU configured to: when charging the first battery from the power generation device is possible and a restriction on operation of the power generation device is predicted during traveling, control the power generation unit such that the first battery is charged from the power generation device and control the power generation unit such that the second battery is charged in a case where an SOC of the first battery is equal to or higher than a threshold; and when the charging is not possible, the SOC of the first battery is equal to or lower than a threshold and an SOC of the second battery is equal to or higher than a threshold and the restriction is predicted during traveling, control the power generation unit such that the first battery is charged from the second battery.

An electrified fire fighting vehicle includes a battery pack, an electromagnetic device, an engine, and a controller. The controller is configured to monitor a state-of-charge of the battery pack, operate the electromagnetic device using stored energy in the battery pack to provide a performance condition including (i) accelerating the electrified fire fighting vehicle to a driving speed of at least 50 miles-per-hour in an acceleration time and (ii) maintaining or exceeding the driving speed for a period of time, and start and operate the engine in response to a start condition to facilitate reserving sufficient stored energy in the battery pack such that the state-of-charge is maintained above a minimum state-of-charge threshold that is sufficient to facilitate the performance condition. The acceleration time is 30 second or less. An aggregate of the acceleration time and the period of time is at least 3 minutes.

A vehicle power conversion apparatus is provided to reduce an overall system size by integrating a motor controller which generates power and a power supply apparatus which converts the power. The vehicle power conversion apparatus includes a driving motor which is connected to an engine and a power converter which selectively converts power in a plurality of modes to generate the power related to an operation of the driving motor. A first battery supplies the power for the conversion or receives the converted power.

A hybrid propulsion update system includes a controller in signal communication with a replaceable battery. The controller includes a tuning parameters storage unit configured to store at least one tuning parameter corresponding to the replaceable battery. The controller is configured to execute at least one optimization algorithm that utilizes the tuning parameters to control operation of the hybrid electric aircraft according to a first performance. The tuning parameters storage unit is configured to receive at least one updated tuning parameter from a controller updating device.

An on-board electrical system includes a motor generator, a high-voltage battery, an electric power acquirer, an auxiliary subsystem, first and second step-down units, and a controller. The electric power acquirer is able to acquire electric power during travel of a vehicle, and able to feed acquired electric power to the high-voltage battery. The auxiliary subsystem includes an auxiliary battery and auxiliary machinery. The controller determines whether or not magnitude of a load on the auxiliary battery is equal to or greater than predetermined magnitude. On the condition that the magnitude of the load is equal to or greater than the predetermined magnitude, the controller allows electric power from the electric power acquirer to be fed to the auxiliary subsystem through the second step-down unit.

The present disclosure relates to systems and methods for managing a state of charge of a hybrid vehicle battery using an eCAT. Electrical energy is provided to a hybrid system for storage at the battery of the hybrid system. A first state of charge of the battery of the hybrid system is determined. Upon determining that the first state of charge is within a predetermined upper range, a determination is made as to whether to increase energy supplied to one or more hybrid vehicle components, the one or more hybrid vehicle components comprising at least the eCAT. At least a portion of the electrical energy is consumed at the eCAT.

A motor vehicle includes: an engine; an electric motor for traveling that is able to perform regenerative driving; a power storage device that is able to supply electric power to the electric motor and to be supplied with electric power from the electric motor; and a control device that controls autonomous driving including automated parking. Interruption control of causing a vehicle to stop and setting a shift position in a neutral range to interrupt autonomous driving is executed when a shift operation is performed during autonomous driving. The shift position is set in a parking range and autonomous driving is ended, and then the power storage device is charged using power from the engine, when a storage ratio of the power storage device reaches less than a predetermined ratio during interruption of autonomous driving that is performed through the interruption control.
