摘要： A driving system includes a first alternating-current rotary electrical machine and a second alternating-current rotary electrical machine. The driving system includes: a first inverter electrically connected to the first alternating-current rotary electrical machine; a second inverter electrically connected to a first end of each of phase windings constituting the second alternating-current rotary electrical machine; a step-up converter; and a third inverter that is electrically connected to a second end of each of the phase windings and transfers power to a second direct-current power source different from the first direct-current power source to drive the second alternating-current rotary electrical machine. The step-up converter raises an output voltage of the first direct-current power source and outputs the output voltage to the first inverter and the second inverter. The second direct-current power source and the first alternating-current rotary electrical machine are connected by a single connection route.

摘要： A hybrid vehicle includes a controller. First control is control of an engine and a motor such that the hybrid vehicle travels by switching between a charge depleting mode and a charge sustaining mode. Second control is control of the engine and the motor such that the hybrid vehicle travels in accordance with a travel plan in which the charge depleting mode or the charge sustaining mode is assigned to each travel section of a travel plan route to a destination. The controller controls the engine and the motor such that a state of charge of an electric power storage device becomes higher in the charge sustaining mode in the second control than in the charge sustaining mode in the first control.

摘要： A control apparatus for a hybrid vehicle determines a scheduled travel route. The control apparatus further determines a downhill section included in the scheduled travel route by using gradient information acquired for a road section at a time when the vehicle has traveled on the road section and using gradient information stored in a navigation database for a road section on which the vehicle travels for a first time. The control apparatus determines a section from a downhill control start point to an end point of the target downhill section as a downhill control section. The downhill control start point is a point located a predetermined first distance closer to the vehicle from a start point of the target downhill section. When the vehicle travels on the downhill control section, the control apparatus executes downhill control.

摘要： A learning algorithm for controlling a battery voltage, which reduces an error of the battery voltage by using a power generation voltage of an alternator while a vehicle is driven includes steps of: calculating, by a processor, a first error voltage indicating a difference between the power generation voltage of the alternator and the battery voltage after the vehicle has been assembled; calculating, by the processor, a second error voltage indicated by updating the difference between the power generation voltage of the alternator and the battery voltage according to an output amount of the alternator and a driving time; and calculating, by the processor, a line-to-line voltage between the alternator and the battery by adding the first error voltage and the second error voltage. This learning algorithm is advantageous since there is no side effect in voltage control such as open-loop control and there is a low voltage control error.

摘要： A work vehicle includes an assist motor that is located opposite an engine with respect to a continuously variable transmission device. The assist motor has an output shaft that extends coaxially with a drive shaft of the continuously variable transmission device and is interlocked with the drive shaft. A motor support platform that supports the assist motor protrudes more outward than the continuously variable transmission device does in a lateral direction relative to a vehicle body. The motor support platform includes a slide movement mechanism, and the slide movement mechanism is configured to change the position at which the assist motor is attached, relative to the continuously variable transmission device, axially of the drive shaft, between a connected position and a disconnected position of the drive shaft and the output shaft.

摘要： An electric vehicle control apparatus includes a first motor generator, a second motor generator, a booster, and a controller. The booster boosts an input voltage to the first motor generator and an output voltage from the second motor generator to expand an operable range of the first motor generator and an operable range of the second motor generator into a first expanded operable range and a second expanded operable range, respectively. The controller controls the first motor generator to drive a load with regenerative power supplied during braking of an electric vehicle and to control the first motor generator to be driven at a first inefficient operating point within the first expanded operable range and to control the second motor generator to be driven at a second inefficient operating point within the second expanded operable range in a case where the regenerative power is used.

摘要： A control method and apparatus of a hybrid vehicle are provided. The control method includes determining whether the speed of a motor exceeds a first threshold value, when supply of power to a battery is cut off and thus the hybrid vehicle is driven by an engine. The speed is then adjusted to be the first threshold value or less, when the speed exceeds the first threshold value.
