Abstract:
A power generation unit includes a motor generator having a rotor with magnet, and a stator with coils driven in a plurality of phases, the coils of the respective phases not being connected to each other; and a driving control part that performs control so that a coil of each phase of the stator is brought into any one of a first state in which torque is generated by the rotor, a second state in which both ends of the coil are electrically released, and a third state in which both ends of the coil are short-circuited.
Abstract:
The purpose of the invention is to provide a hybrid vehicle control system that can start an engine (1) irrespective of a motor rotational speed or runnig scenes. In the hybrid vehicle control device, upon receive of an engine startup request, the engine is started by engaging a first clutch (2) provided between the engine (1) and a motor (3) using the torque of the motor (3) (surplus torque TmOV). A second clutch (4) provided between the motor (3) and the drive wheel (9) is disengaged by a second clutch control means (Step S4) to reduce the motor rotation speed (Nm) as a result of motor (3) rotational speed control by a motor rotation speed-controlling means (Step S6). The control system may thus increase the maximum motor output enable torque to ensure the start of the engine by the surplus torque irrespective of a motor rotational speed or driving scene.
Abstract:
An electric powered vehicle includes a motor (MG2), an inverter (22), a main power storage device (BA), and a plurality of sub power storage devices (BB1, BB2). A converter (12B) is connected to a selected one of the plurality of sub power storage devices (BB1, BB2) to perform voltage conversion bidirectionally between the selected sub power storage device and an electric power feeding line (PL2). A control device (30) executes a disconnection process to disconnect a selected sub power storage device from the converter (12B) based on a state of charge of the selected sub power storage device when there is no new sub power storage device that can replace the selected sub power storage device. Further, the control device (30) executes a braking process for the inverter (22) for regenerative braking by the motor (MG2). The control device (30) prohibits, during execution of one process of a disconnection process and braking process, the other process.
Abstract:
An electrical powered vehicle (100) includes a secondary self-resonant coil (110), a secondary coil (120), a rectifier (130), and a power storage device (140). The secondary self-resonant coil (110) is configured to be magnetically coupled with a primary self-resonant coil (240) of a power feeding device (200) by magnetic field resonance, and allow reception of high frequency power from the primary self-resonant coil (240). The secondary coil (120) is configured to allow reception of electric power from the secondary self-resonant coil (110) by electromagnetic induction. The rectifier (130) rectifies the electric power received by the secondary coil (120). The power storage device (140) stores the electric power rectified by the rectifier (130).
Abstract:
An apparatus (100) controls a running state of a hybrid vehicle, wherein the hybrid vehicle is configured to select, as a running mode, an EV running mode and a HV running mode, the hybrid vehicle is configured further to select an intermittent operation mode for repeating acceleration running and coasting by intermittently driving the drive wheels, in the HV running mode. The apparatus switches the EV running mode to the intermittent operation mode according to a comparison result between a power storage amount of the power storing device and a convergence value of the power storage amount in a case where the intermittent operation mode is selected, if the intermittent operation mode is required during steady running by the EV running mode.
Abstract:
A vehicle (100) includes: a power storage device (110); a motor generator (130) that generates traveling driving power using electric power from the power storage device (110); an ECU (300); and an inclination detecting unit (200) for detecting inclination of a road surface. The ECU (300) performs power changing driving in which the vehicle (100) is traveled while switching the motor generator (130) between a first state and a second state, driving power of a first level being generated in the first state, driving power smaller than the driving power generated in the first state being generated in the second state. When the ECU (300) recognizes, based on the inclination detected by the inclination detecting unit (200), that the vehicle (100) is traveling on a road surface having a slope, the ECU (300) eases up at least one of an upper limit value and a lower limit value of SOC of the power storage device (110). In this way, energy efficiency of the vehicle (100) is improved and driveability on a road having a slope is improved.
