  • 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: 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: 10392005
    Abstract: A hybrid electric vehicle including a gradient acquiring portion which acquires a gradient of a road surface on which the vehicle is running, and a control portion which determines whether the vehicle runs on a first driving by means of power from the motor by releasing the engagement and disengagement portion, or on a second driving by means of power from at least the internal combustion engine by applying the engagement and disengagement portion. The control portion restricts a switch from the second driving to the first driving when the gradient of the downward slope is equal to or greater than a threshold value. The control portion holds the second driving when the switch from the second driving to the first driving is restricted, even though the control portion obtains a request for a switch to the first driving while the vehicle runs the downward slope on the second driving.

  • Patent number: 9453575
    Abstract: A control device of a twin-clutch transmission includes a gear operation mechanism driven by a single actuator mechanism . The gear operation mechanism performs a selection operation to select a synchromesh unit to operate from a plurality of synchromesh units and a shift operation to drive the selected synchromesh unit to an engagement position (in-gear position) corresponding to a shift position. In the control device, based on a deceleration rate of a vehicle, a determination is made to allow or disallow continuation of the shift operation at a change of a shift position to a target shift position. When a determination is made to disallow continuation of the shift operation, only the selection operation is performed, and the shift operation is prohibited. When a determination is made to allow continuation of the shift operation, the shift operation is allowed.
