A control device of a hybrid vehicle 1, 1′ comprises a driving plan generating part 61 configured to set in advance a driving mode and a target state of charge of the battery; and an output control part 62 configured to control outputs of the internal combustion engine and the motor. If the hybrid vehicle is being driven from a departure point through at least one via point to a final destination, the driving plan generating part is configured to divide a plurality of routes into pluralities of sections, and set a driving mode of all sections of at least one route to an EV mode. If a value of the target state of charge minus an actual state of charge of the battery becomes larger than a threshold value, the output control part is configured to change the driving mode in a section of a non-EV route.

A vehicle includes a traction battery, circuitry including a switch and a capacitor, and a monitoring chip configured to draw power from a cell of the traction battery via the circuitry responsive to the switch being closed. The circuitry is configured to open the switch to disconnect the cell from the chip and power the chip via the capacitor for a predetermined period. Powering the chip via the capacitor prevents power down of the chip during the predetermined period. The circuitry opens the switch responsive to engine cranking.

A vehicle includes a motor, an inverter configured to drive the motor, an electric power storage device connected to the inverter through a power line, and a control device configured to control the inverter. When zero torque control for controlling the inverter such that torque of the motor becomes zero is executed, the control device is configured to control the inverter using a carrier frequency higher than when the zero torque control is not executed.

An apparatus and a method for controlling a hybrid vehicle are provided. The apparatus includes an engine that generates power by combusting fuel and a drive motor that supplements the power from the engine and operates selectively as an electric generator to produce electrical energy. A clutch is disposed between the engine and the drive motor and a battery supplies electrical energy to the drive motor and is charged with the electrical energy produced by the drive motor. Multiple electric superchargers are installed in multiple intake lines through which outside air to be supplied into a combustion chamber of the engine flows. A controller determines an operation mode of the multiple electric superchargers based on required power of a driver and a state of charge (SOC) of the battery and adjusts the power output from the engine and the power output from the drive motor.

A powertrain system includes an electric motor for driving a vehicle; a battery; an internal combustion engine; an electric generator; a motor inverter connected in parallel to the battery, and converting DC electric power of the battery into AC electric power and supplying it to the electric motor; a generator inverter connected in parallel to the battery, and converting AC electric power generated by the electric generator into DC electric power and supplying it to the battery; and a control device.

A method for estimating a magnet temperature of a rotor magnet within a rotary electric machine includes, while a rotor of the electric machine is stationary, injecting a high-frequency voltage component onto a control voltage of the electric machine, via a controller, to generate an adjusted voltage command, and extracting a high-frequency component of a resulting current as an extracted high-frequency component. The method also includes calculating an inductance value of the electric machine using the extracted high-frequency component of the resulting current. The magnet temperature is estimated using the calculated inductance value and an angular position of the rotor. The method includes controlling an operation of the electric machine using the estimated magnet temperature. An electric powertrain uses the electric machine and controller noted above.

A motor control apparatus and method for damping engine vibration are provided. The apparatus includes a data collection device that collects engine information and motor information and a processor that determines a magnitude of engine torque vibration using the engine information and the motor information. A weighting value is determined by determining a position of a piston in a cylinder of an engine, ignition timing, an engine angular acceleration, and an engine velocity. A motor arti-phase torque is calculated by reflecting the determined weighting value in the magnitude of the engine torque vibration and a motor is operated based on the motor anti-phase torque to cancel out the engine torque vibration.

A vehicle includes an engine, a motor generator, a battery, and an ECU, and is configured to selectively perform EV running and engine running. When requested power is smaller than reference power, ECU calculates an engine fuel consumption ratio h1 when the engine outputs power resulting from addition of optimal charging power for the battery to the requested power, and determines whether the engine fuel consumption ratio h1 is larger than an EV criterion line resulting from addition of a margin K to a battery equivalent fuel consumption ratio F. When the engine fuel consumption ratio h1 is larger than the EV criterion line, ECU selects EV running, and otherwise selects engine running. The ECU calculates the margin K by referring to an FK map which defines correspondence between the battery equivalent fuel consumption ratio F and the margin K with which an SOC is converged to a target range.

A method for controlling a hybrid vehicle is disclosed. The method comprises calculating, for a low-emission area on the vehicle's current travel, a first energy to travel the low-emission area in a first driving mode, determining whether the hybrid vehicle is capable of traveling the low-emission area in the first driving mode using current energy of a vehicle battery, and when it is determined that the hybrid vehicle is incapable of traveling the low-emission area in the first driving mode using current energy of the vehicle batter, initiating a battery charging operation before the vehicle enters the emission-restricted area.

A hybrid vehicle comprising an internal combustion engine, a hybrid system, a parking brake, a gear box and an electronic control system is provided. A method for controlling the method comprises charging the hybrid vehicle by receiving and storing electric energy, which enables a safe way of starting the internal combustion engine during the charging. An electronic control system is configured to: detect a starting attempt of the internal combustion engine during the receiving and storing of electrical energy; ensure that the hybrid vehicle is ready for a start of the internal combustion engine, which includes ensuring that the gear box is in a neutral gear and that the parking brake is applied; and thereafter start the internal combustion engine during the receiving and storing of electrical energy.
