  • Patent number: 11472294
    Abstract: A braking control apparatus to be installed an electric vehicle includes an acceleration and deceleration operation member, a controller, and a recognizer. The acceleration and deceleration operation member receives an acceleration request in accordance with an operation amount in a first direction from a neutral position, and receive a deceleration request in accordance with an operation amount in a second direction from the neutral position. The controller controls an amount of power regenerated by a rotary electric machine driven by wheels in accordance with the operation amount in the second direction. The recognizer recognizes a preceding vehicle traveling ahead of the electric vehicle. Upon detection of the preceding vehicle at a relative distance from the electric vehicle that is equal to or less than a threshold, the controller performs braking suppression control to decrease the amount of power regenerated in accordance with the operation amount in the second direction.

  • Patent number: 8808143
    Abstract: There is provided an output control device for a vehicle. The device includes an accelerator operator to receive an output adjustment operation of a drive power of a vehicle; a brake operator to receive a braking operation of a braking device; an accelerator operation amount detection unit for detecting an operation amount of the accelerator operator; a brake operation force estimation unit for estimating an operation force of the brake operator; and an output suppression control unit for suppressing an output of the drive power regardless of a state of the accelerator operator, in the case where for a predetermined time or longer, a state continues in which the operation amount of the accelerator operator is greater than or equal to a predetermined accelerator threshold value, and the operation force estimated by the brake operator is greater than or equal to a predetermined brake threshold value.
