  • Publication number: 20220144245
    Abstract: A management ECU of an electrical vehicle creates a travelling plan in which any one of travelling modes is assigned to each of traveling sections of a scheduled traveling route from a current position of the electrical vehicle to a destination and control the travelling modes based on the travelling plan. When a total estimated value of an amount of electric power required for traveling in each of the traveling sections in a first traveling mode exceeds a current SOC, the management ECU extracts a section in which an output estimated value exceeds a second predetermined value as a planning target section, and creates the traveling plan in which a second traveling mode in which a usage amount of electric power of a storage battery is smaller than that in the first traveling mode is assigned preferentially to a section farther from the electrical vehicle among the planning target sections.

  • Publication number: 20220144246
    Abstract: When a scheduled traveling route is changed during travelling of an electrical vehicle, a management ECU of the electrical vehicle maintains control of a travelling mode based on a travelling plan created based on the scheduled traveling route before the change, in accordance with a result of comparison between first attribute information and second attribute information, the first attribute information indicating an attribute of at least one section, which is located within a predetermined distance from a section in which the electrical vehicle is located and located in a vehicle travelling direction, of the scheduled traveling route before the change, the second attribute information indicating an attribute of at least one section, which is located within a predetermined distance from a section in which the electrical vehicle is located and located in a vehicle travelling direction, of the scheduled traveling route after the change.

  • Publication number: 20220055606
    Abstract: A control device of a vehicle includes a discharge control unit configured to, in a case where a regenerative section is included in a scheduled traveling route of the vehicle, perform a discharge control for increasing a discharge amount of a power storage device as compared with a case where the regenerative section is not included in the scheduled traveling route. The discharge control unit is configured to determine a target discharge electric power amount, which is a target value to be discharged before the vehicle reaches a start point of the regenerative section, based on a predicted regenerative electric power amount that is capable of being generated in the regenerative section, and perform the discharge control based on the target discharge electric power amount and a parameter that changes in accordance with a distance from the vehicle to the start point.

  • Publication number: 20220055607
    Abstract: A control device of a vehicle includes a discharge control unit. The discharge control unit, in a case where a plurality of regenerative sections are included in a scheduled traveling route, extracts a first regenerative section on a vehicle side, a second regenerative section closest to the first regenerative section, and a dischargeable section between the first regenerative section and the second regenerative section. The discharge control unit, in a case where a predicted regenerative electric power amount in the first regenerative section is greater than a predicted discharge electric power amount in the dischargeable section, sets a section obtained by merging the first regenerative section, the second regenerative section, and the dischargeable section as a control target section, and performs the discharge control based on a remaining capacity of a power storage device and a predicted regenerative electric power amount in the control target section.

  • Patent number: 11091058
    Abstract: A fuel cell system includes a FC, a TRC, an oxygen-containing gas supply apparatus, a battery, and an ECU. The ECU is capable of performing power consumption control which allows the oxygen-containing gas supply apparatus to consume electrical energy during regeneration of the TRC. The ECU is configured to determine a charge margin with respect to a charge limitation value of the battery, in a manner that the charge margin set after the power consumption control starts becomes smaller than the charge margin set before the power consumption control is performed.

  • Patent number: 10145329
    Abstract: A control system for an internal combustion engine, which is capable of quickly and properly ensuring excellent fuel economy of the engine even when atmospheric pressure has changed. The control system includes an ECU. The ECU performs weighted average calculation on lowland map values and highland map values, based on atmospheric pressure, to thereby calculate map values of a demanded torque that minimize a fuel consumption ratio of the engine in the atmospheric pressure, and calculates engine demanded output. The ECU calculates demanded torque and demanded engine speed using the map values and the engine demanded output, respectively. The ECU controls the engine using the demanded torque.

  • Patent number: 9925976
    Abstract: A hybrid electric vehicle drive apparatus has a setting portion for setting a limit value of a driving torque that a motor outputs when driving a hybrid electric vehicle by the power of the motor only, based on a maximum torque that the motor enables to output and a starting torque used to start an internal combustion engine by the motor. The setting portion sets the limit value to a first value and sets the limit value to a second value which is greater than the first value when a vehicle speed of the vehicle does not increase even though an accelerator pedal position degree increases while the vehicle is being driven only by the motor.

  • Patent number: 9457798
    Abstract: A hybrid vehicle determines whether or not the drive mode thereof is shifted from a series drive to an engine direct coupled drive with a power transmission engaging/disengaging portion applied, derives a rotational speed at a drive wheel side of the power transmission engaging/disengaging portion which corresponds to a driving speed as an applying rotational speed of an internal combustion engine at which the power transmission engaging/disengaging portion is applied, and applies the power transmission engaging/disengaging portion by controlling the operation of the internal combustion engine when a difference in rotational speed between the rotational speed of the internal combustion engine and the applying rotational speed becomes equal to or smaller than a predetermined value after the shift to the engine direct coupled drive is determined.
