Methods and systems are provided for an electric drivetrain. In one example, the electric drivetrain system includes a first and a second electric motor-generator rotationally coupled to a planetary assembly that is rotationally coupled to a drive axle via an output gear. The system further includes a controller that is configured to, during a first operating condition, operate each of the first and second electric motor-generators in a motor mode or a generator mode and hold the output gear at a zero speed.

An opening-closing body control device for a vehicle includes: an opening-closing control unit configured to control an operation of an opening-closing body provided in an opening portion of a vehicle by controlling energization of a motor serving as a drive source. When the opening-closing body being moved based on a driving force of the motor is to be stopped, the opening-closing control unit sets a free running period during which free rotation of the motor is allowed, and executes brake control for generating a braking force in the motor after the free running period elapses.

A vehicle power port device for use with a vehicle having a rechargeable lithium ion battery, the device including one or more power ports installed in, on, or within the vehicle, the one or more power ports configured to connect to and power an electrical device or equipment located external to the vehicle and a power cable connecting the rechargeable lithium ion battery directly, or indirectly, to the one or more power ports.

An acquisition unit that acquires vehicle information related to a vehicle state of a vehicle; a determination unit that determines whether the vehicle has traveled in a state in which energy consumption efficiency of the vehicle is poor within a predetermined time from a predetermined driving operation of the vehicle based on the vehicle information acquired by the acquisition unit; and a display control unit that causes a display unit to display the number of times of traveling in the state per unit time within the predetermined time from the predetermined driving operation, the traveling being determined by the determination unit, are included.

An example operation includes one or more of determining an efficiency, related to a current event of a transport, is lower than a threshold, and restricting a least intrusive future event of the transport, unrelated to the current event, until the efficiency is at or above the threshold.

A mobile compressed foam firefighting unit comprising a mixing chamber connected at the outlet to the foam feeder, and the following systems connected to the mixing chamber inlet: a water supply system comprising a water pump and a water pump drive, a foam concentrate supply system comprising a foam pump and a foam pump drive, and an air supply system comprising an air compressor and an air pump drive. The system includes a drive motor, and drives of the air compressor and the foam pump comprise variable hydraulic transmissions kinetically connected to the drive motor, and the system is equipped with a water flow meter, a throttle valve with an electric drive and a check valve, and an electronic control unit of the throttle valve installed in the water supply pipe between the water pump and the mixing chamber.
