A handleless door entry system for a vehicle. The system including: an occupant detection component including a first detection component and a second detection component, wherein the first detection component is configured to detect a device within a predetermined distance of the handleless door entry system, and wherein the second detection component is configured to detect an intent of an object or individual approaching the handleless door entry system.

Apparatus and method for determining access intention recognition for use in a vehicle with a handleless door

A ripple circuit includes a sensor, and oscillator circuit and a logic gate. The sensor monitors operation of a motor that is powered by a power signal provided by a motor circuit. The sensor outputs a data signal having a first state or a second state based on the operation of the motor. The oscillator circuit generates an oscillating signal having a fixed frequency. The logic gate includes at least one input in signal communication with the sensor and the oscillator circuit and at least one output in signal communication with the motor circuit. The logic gate selectively outputs the oscillating signal based on the first state or the second state of the data signal to generate a modulated signal. The logic gate is configured to deliver the modulated signal to the motor circuit.

A motor control system includes a direct current (DC) motor and a ripple count circuit. The DC motor includes a rotor induced to rotate in response to a drive current generated by a supply voltage. The rotation of the rotor generates a mechanical force that drives a component. The ripple count circuit includes an active filter circuit and a parasitic pulse cancellation circuit. The active filter circuit is configured to filter the drive current and to generate a pulsed signal containing at least one parasitic pulse. The parasitic pulse cancelation circuit is in signal communication with the ripple count circuit to receive the pulsed signal and to output a ripple count signal based on the pulsed signal. The ripple count signal excludes the at least one parasitic pulse.
