Patent ID: 7064506

Claim:
A method for controlling a vehicle power seat motor, the method comprising: generating at least one control signal using a controller; and adjusting the speed of a motor coupled to a vehicle seat mechanism in response to the at least one control signal such that the speed of the motor is maintained to a predetermined curve, the predetermined curve comprising a ramp up segment, a steady state segment, and a ramp down segment, the ramp up segment substantially following an S-curve described by an equation SP=(T/(T+exp(B−C*T)))*(SS), wherein B and C are predetermined constants, SP is speed of the motor at a particular point in time during the ramp up segment, SS is the speed of the motor during the steady state segment, and T is time referenced to start of the ramp up segment and wherein maintaining the speed of the motor to the predetermined curve reduces at least one of mechanical wear, erratic motion, and noise of the respective seat mechanism.
