  • Patent number: 9616774
    Abstract: A vehicle seat controller includes a feedback controller, a speed instruction value setting unit, and an entrapment determination unit. The feedback controller performs speed feedback control so that a rotation speed of the motor follows a speed instruction value based on a difference of the speed instruction value and an actual speed of the rotation speed of the motor. The speed instruction value setting unit sets the speed instruction value in accordance with a position of the vehicle seat. The entrapment determination unit determines entrapment of a foreign object entrapped by the vehicle seat when the vehicle seat is motor-driven. When the entrapment determination unit makes a foreign object entrapment determination, the speed instruction value setting unit changes the speed instruction value for an entrapment position of the vehicle seat to a low speed value that is smaller than a predetermined initial value.

  • Patent number: 9548682
    Abstract: An actuator (1M, 1S) with a motor (12) and a motor controller (11) is configurable to operate as a master or a slave to another actuator which is coupled mechanically for driving a common load. For the case where the actuator (1M) is set as the master, the motor controller (11) receives on an input terminal (Y3) an external position control signal (pC), generates a motor control signal (sC) for controlling the motor (12) based on the position control signal (pC), and supplies the motor control signal (sC) to an output terminal (U5) for controlling a slave. For the case where the actuator (1S) is set as the slave, the motor controller (11) controls the motor (12) by supplying to the motor (12) the motor control signal (sC) received from the master. Controlling the actuators with a master improves workload balancing and reduces damages to transmission mechanics of the actuators.

  • Patent number: 8912808
    Abstract: An apparatus and method for determining characterizing attributes of an actuator is provided. An actuator may be moved to a maximum capacitance position. At the maximum capacitance position, an initial measurement of the actuator capacitance is made. The actuator is moved a predetermined increment toward a first extreme position, and the actuator capacitance is again measured. If the capacitance changed by a threshold amount, the signal preceding the signal that caused the actuator to move is recorded as an approximate response curve end point, or the first extreme position. The actuator is again moved a predetermined increment toward a second extreme position. After each move, the capacitance is measured. If it is determined the capacitance did change by a threshold amount from the previously measured capacitance, the signal related to the previously measured capacitance is recorded as an approximate response curve end point, or the second extreme position.
