  • Publication number: 20220252150
    Abstract: A method is configured to compensate control reactivity of a shift-by-wire system in which shift ranges of an automatic transmission are changed by a motor. The method for compensating control reactivity may ensure a consistent response of the motor by including a compensation logic that measures a necessary driving time of the motor that was taken to rotate a detent plate from a current position to a target range, determines whether the motor is in an over-response state or an under-response state by comparing the measured taken time with a pre-stored setting value, accumulates an over-response or under-response detection count, performs compensation of decreasing or increasing an instruction value (a duty value) of the motor in accordance with the accumulated over-response or under-response detection count.

  • Patent number: 11391367
    Abstract: A method of detecting a gear shift position of an electric shift-by-wire system is proposed. The method includes setting, as a reference position, a motor position at a time point when shift is completed to a target shift stage; rotating the motor until the motor no longer rotates in a P stage-engaging direction from the reference position; measuring a rotation amount of the motor with respect to the reference position; and determining the gear shift position by determining that the reference position is a P stage when the measured rotation amount of the motor is less than or equal to a predetermined first reference value, and the reference position is not the P stage when the measured rotation amount of the motor is greater than the first reference value.

  • Patent number: 10975965
    Abstract: The present invention relates to a position learning system for an electric shift-by-wire system, which senses changes in the load of a motor according to operations of a four-stage detent plate and a detent spring to learn positions of shift stages of the electric shift-by-wire system, the position learning system including: a sensor for sensing the current generated from the motor; and a controller for receiving current data until a shift stage P is switched to a shift stage D or the shift stage D is switched to the shift stage P from the sensor, learning positions of shift stages R and N through the received current data, and performing offset operations on the basis of the learned positions of the shift stages R and N to learn positions of the shift stages P and D.

  • Patent number: 9548712
    Abstract: An apparatus and a method for controlling a volume in a mobile terminal are provided. The apparatus includes a motion detector and a controller. The motion detector outputs motion information from a user's movement. The controller determines the user's activity from the motion information output from the motion detector, and determines an appropriate output volume level responsive to the activity.

  • Publication number: 20100234181
    Abstract: An assembly for measuring an exercise amount corresponding to a user's motion is provided. The assembly includes mounting kits and a unit for measuring an exercise amount. The unit is selectively fixed to one of the mounting kits that are placed on designated body portions of the user to measure an exercise amount corresponding to a motion of the user by applying an algorithm corresponding to the selected mounting kit. The assembly makes accurate measurement of an exercise amount possible by detecting various mounting locations of the unit mounted on a user and automatically applies an algorithm optimized for different locations.
