Abstract
A motor vehicle seat adjuster includes a DC motor and a control system operably connected to the motor to control seat motion to a desired motion profile. Power to the motor is variable from less than 100% of normal power to greater than 100% of normal power. The desired motion profile preferably includes a normal operating power and a boost operating power and the control system automatically increases motor power to the boost operating power after one of a predetermined period of time, a predetermined distance of travel, or a predetermined sensed condition. Parameters of the motion profile are preferably customizable.
