  • VEHICLE STABILITY CONTROL DEVICE
    Publication number: 20180170364
    Abstract: A vehicle stability control device includes a yaw moment generation device and a control device. A variation yaw moment generated by simultaneous turn and acceleration/deceleration is expressed as a function of a longitudinal acceleration and a lateral acceleration. A longitudinal force and a lateral force of a tire have non-linear load dependency. The variation yaw moment when assuming that the load dependency is linear is a first variation yaw moment. The variation yaw moment considering the non-linear load dependency is a second variation yaw moment that is expressed as a product of the first variation yaw moment and a correction gain. In vehicle stability control, the control device controls the yaw moment generation device to generate a counter yaw moment counteracting the second variation yaw moment, based on the longitudinal acceleration, the lateral acceleration, and the correction gain.

  • Engagement device and automatic transmission
    Patent number: 9976604
    Abstract: A translational force Fh to one side in a rotational axis direction is caused to act from a hydraulic piston to a sleeve when an engaged stage between an engagement tooth and an engaged tooth is maintained, so that translation of the sleeve to the other side in the rotational axis direction and consequent disengagement of the engagement tooth and the engaged tooth can be prevented. Therefore, the engaged state between the engagement member and the engaged member can be stably maintained regardless of the condition of the torque acting from the drive source to the engagement member.
