A parallel hybrid drive train, in particular for a working machine, includes an internal combustion engine (1), an electrical machine (2) and hydraulic aggregates (3, 4, 5, 9) for driving working devices (6-8) and for moving the working machine. In order to increase the efficiency, the rotational speed of the internal combustion engine is lowered, that is to say the load point is moved. Increased power requirements are detected via a driver input and provide a desired rotational speed. The electrical machine assists the acceleration of the internal combustion engine to said desired rotational speed.

A method and a system are described for controlling power dissipation in an electric drive system for a hybrid electrical vehicle including determining the stator current of an electrical machine providing a maximum achievable power dissipation in the electrical drive system and determining a maximum available braking torque of an electrical machine.

In an electric vehicle, a power supplier includes a software type condenser charging circuit and a hardware type condenser charging circuit. The software capacitor charging circuit operates when a controller controls the software type condenser charging circuit while monitoring a voltage between opposite ends at an initial charging stage. The hardware type condenser charging circuit is operated when the controller controls the hardware type condenser charging circuit without monitoring the voltage between the opposite ends of the DC-link condenser or by direct switching manipulation of a user.

When an acceleration degree of a vehicle in a state of an electric motor generating torque as motive power is small compared to the acceleration degree of the vehicle in a state of being propelled using that torque, a user is notified by displaying a warning on a display which is a notification device of the vehicle.

A control device for performing start assist control for an internal combustion engine includes: a first start assist processing unit that executes a first start assist process that brings a first engagement device into slip engagement at a first engagement pressure while increasing a torque generated by a rotating electrical machine; and a second start assist processing unit that increases, when the first start assist process fails to start the internal combustion engine, an engagement pressure of the first engagement device to a second engagement pressure higher than the first engagement pressure while increasing the torque generated by the rotating electrical machine. The second start assist processing unit determines the second engagement pressure on the basis of a rotational speed of the internal combustion engine in the first start assist process.

An active vibration reduction control apparatus for a hybrid electric vehicle includes: a reference signal generator generating a reference signal and a first phase based on a first rotational angle of a first motor; a vibration extractor extracting a vibration signal from a second motor; a coefficient determiner determining a filter coefficient which minimizes a phase difference between the reference signal and the vibration signal; a phase determiner detecting a second phase which corresponds to the phase difference using a first speed signal of the first motor and the filter coefficient; a phase deviation amount detector detecting a third phase for compensating for a phase delay; and a synchronization signal generator generating an antiphase signal of a shape of an actual vibration in order to determine a compensating force of the first motor.

A system for navigating a vehicle automatically from a current location to a destination location without a human operator is provided. The system of the vehicle includes a global positioning system (GPS) for identifying a vehicle location and a communications system for communicating with a server of a cloud system. The server is configured to identify that the vehicle location is near or at a parking location. The communications system is configured to receive mapping data for the parking location from the server, and the mapping data is at least in part used to find a path at the parking location to avoid a collision of the vehicle with at least one physical object when the vehicle is automatically moved at the parking location. The mapping data is processed by electronics of the vehicle so that when the vehicle is automatically moved collision with the at least one physical object is avoided and the electronics of the vehicle is configured to process a combination of sensor data obtained by sensors of the vehicle. The processing of the sensor data uses image data obtained from one or more cameras and light data obtained from one or more optical sensors.

Provided is a traveling apparatus including at least, with respect to a traveling direction, a front wheel and a rear wheel and on which a user rides when travelling. The traveling apparatus includes a front wheel supporting member configured to rotatably support the front wheel, a rear wheel supporting member configured to rotatably support the rear wheel, an adjusting mechanism configured to adjust a wheel base length between the front wheel and the rear wheel by changing a relative position of the front wheel supporting member and the rear wheel supporting member, and a driving unit configured to drive at least one of the front wheel and rear wheel. The wheel base length adjusted by the adjusting mechanism is associated with a speed of the traveling apparatus achieved by driving the driving unit in such a way that the longer the wheel base length, the greater the speed becomes.

A first electric power generation device configured to produce an accessory voltage according to a first instruction voltage. A second electric power generation device configured to produce the accessory voltage according to a second instruction. An electric control unit is configured to execute crank position stop control for stopping a crank of the engine at a target position when the engine is stopped by controlling the first electric power generation device such that a current is circulated in the first electric power generation device and the rotating electric machine generates braking torque. The electric control unit is configured to execute the crank position stop control in a state in which the second instruction voltage is equal to or higher than the first instruction voltage.

A vehicle is provided that comprises two or more radio frequency (RF) antennas and two or more RF transceivers to communicate wirelessly sensitive information associated with a user of the vehicle (the two or more RF antennas being at different physical locations on an exterior of the vehicle). The vehicle determines which one of the two or more RF antennas is receiving a strongest signal from a common signal source, selects a first RF transceiver associated with the RF antenna with the strongest signal to send the sensitive information associated with the user to the common signal source, and sends the sensitive information associated with the user to the first RF transceiver for transmission to the common signal source.
