According to a control method for a hybrid vehicle that is caused to run by a drive motor as a load being supplied with electric power of a battery and electric power generated by an electric generator, a total distance to empty is calculated on the basis of a shortage of a generating power output of the electric generator with respect to a required running power output and an amount of charge remaining in the battery. Specifically, a length of time for which the shortage of the generating power output of the electric generator with respect to the required running power output is covered by the amount of charge remaining in the battery is calculated, and a distance that the hybrid vehicle can run for this length of time is set as a total distance to empty.

A hybrid drive transmission unit for a vehicle with an internal combustion engine and an electric motor for the drive part, includes a power-split transmission with sub-transmissions and a torsion-damping unit with a gyrating mass interconnected between the internal combustion engine and the power-split transmission. A clutch is interconnected between the internal combustion engine and the torsion-damping unit, by which the internal combustion engine can be activated, switching from the electromotive operating mode.

A working machine includes a prime mover for supplying torque to the driving wheels of the working machine, and a transmission line arranged between the prime mover and the driving wheels for transmitting torque from the prime mover to the driving wheels. The transmission line includes a gearbox arranged between the prime mover and the wheels, and the working machine further includes at least one hydraulic machine in a hydraulic system for moving an implement arranged on the working machine and/or steering the working machine, and an electric machine for driving or braking the driving wheels and/or for driving or braking the at least one hydraulic machine. The electric machine is arranged in parallel with the prime mover with respect to the transmission line and is mechanically connected to the transmission line between the prime mover and the gearbox. The gearbox is a continuously variable transmission having a variator unit, and the gearbox has an operation mode where the rotation speed of the output shaft of the gearbox is zero or close to zero independently of the rotation speed of the input shaft of the gearbox at the same time as torque can be transmitted from the input shaft to the output shaft.

A vehicle includes a low-voltage battery, a high-voltage battery, and a converter that decreases voltage provided from the high-voltage battery to the low-voltage battery. A system controller of the vehicle is programmed to use the converter, in a key-off cycle, to charge the low-voltage battery a calibrated number of times that the low-voltage battery drops below a predefined state-of-charge threshold, and send a wireless notification a subsequent time the low-voltage battery drops below the threshold. A notification is sent to a predefined contact address when a periodically computed state of charge of a low-voltage battery of a vehicle falls below a predefined threshold. Using a converter, voltage provided from a high-voltage battery of the vehicle to the low-voltage battery is decreased to charge the low-voltage battery responsive to receipt from the contact address of a response indicating approval of the charge.

An automatic driving control system includes power sources, a relay device changing connection states of the power sources, a relay control device controlling the relay device, a status recognizing unit recognizing a status of the own vehicle on a planned traveling route, and an automatic driving control unit controlling automatic driving. The status recognizing unit recognizes that a collision probability of a collision with an object during the automatic driving is a predetermined threshold or more, and also recognizes a damage-expected power source included in the power sources and expected to be damaged in a collision with the object. When the collision probability is the predetermined threshold or more, the automatic driving control unit instructs the relay control device to disconnect the damage-expected power source from particular auxiliary units and to connect, to the particular auxiliary units, a power source that is not the damage-expected power source.

A vehicle control system including a plurality of systems configured to control a plurality of different functions, respectively, of a vehicle, and the plurality of systems each include: a plurality of input sections; an input adjustment section configured to adjust one or more requests, inputted through the plurality of input sections, for controlling a predetermined vehicle function; a plurality of output sections associated with the vehicle function; and a management section configured to manage operations of the plurality of output sections, based on a request adjusted by the input adjustment section. The management sections each have a communication function that allows information that is associated with management based on at least the adjusted request to be transmitted to and received from each other.
