  • Patent number: 11173917
    Abstract: A control apparatus configured to control a four-wheel drive vehicle configured to drive right and left front wheels and right and left rear wheels includes an electronic control unit. The electronic control unit calculates a vehicle body speed based on rotation speeds of the wheels and a cumulative value of accelerations in a longitudinal direction of the vehicle. The accelerations are detected by an acceleration sensor. The electronic control unit calculates the vehicle body speed based on the cumulative value of the accelerations. The electronic control unit calculates a correction value based on a lowest rotation speed among the rotation speeds of the wheels under a predetermined condition. The electronic control unit performs correction by using the correction value to make the vehicle body speed closer to a vehicle body speed conversion value of the lowest rotation speed.

  • Patent number: 11167818
    Abstract: A human-powered vehicle control device includes an electronic controller that controls a motor. The motor assists in propulsion of a human-powered vehicle including a transmission configured to change, in steps, a first ratio of a rotational speed of a drive wheel to a rotational speed of a rotary body to which human drive force is input. The controller changes a motor control state from a third control state to a fourth control state when the first ratio is changed by the transmission or a signal is received for changing the first ratio. The controller changes the motor control state from the fourth control state to a fifth control state in accordance with a value related to at least one of a speed of the human-powered vehicle, the human drive force, an inclination angle of the human-powered vehicle, and a state of a rider of the human-powered vehicle.

  • Patent number: 11162548
    Abstract: A method for operating a dual-clutch transmission of a motor vehicle, wherein a first clutch is operated closed or engaged and in this way a first transmission branch is driven, in which a current actual gear is engaged, and in a pre-selection phase for a gear changed to a desired gear in a second transmission branch, the desired gear is engaged, and in a second clutch, a clutch hydraulic system is filled and, in this way, the second clutch is closed. The gear change shall be made faster. The filling of the clutch hydraulic system is begun already during the pre-selection phase, and, in this case, the clutch hydraulic system is filled in the pre-selection phase but at most up to reaching a touch point of the second clutch.

  • Patent number: 11155162
    Abstract: Disclosed is a travel control apparatus applied to a vehicle which includes two coupling apparatuses individually changing coupling torques between a drive output part for secondary drive wheels and left and right secondary drive wheel axles and in which the ratio of rotational speed of the drive output part to the average of rotational speeds of primary drive wheels is greater than 1. The apparatus generates a yaw moment in a turning direction by using driving force. When a demand of further increasing the yaw moment arises, the control apparatus renders the braking force of the primary drive wheel on the turning locus inner side coincident with a target braking force changing with the travel state of the vehicle and decreases the coupling torque of the coupling apparatus corresponding to the secondary drive wheel on the turning locus outer side. As a result, generation of an anti-spin moment is avoided.
