Claim 3:
4. A vehicular door opening control system, the vehicular door opening control system comprising:
a radar unit disposed at a vehicle equipped with the vehicular door opening control system, wherein the radar unit has a field of sensing adjacent to and exterior of a door of the vehicle, and wherein the radar unit transmits emitted radar signals and receives reflected radar signals reflected from an object present in the field of sensing;
a scanning actuator coupled to the radar unit and operable to move the radar unit relative to the door to create a variation between the transmitted radar signals and the reflected radar signals indicative of a shift between the radar unit and the object;
an electrically powered actuator coupled to the door and operable to, when electrically powered, move the door relative to the vehicle to open the door;
an electronic control unit (ECU) in communication with the radar unit, the scanning actuator and the electrically powered actuator, wherein the ECU is operable to operate the radar unit to transmit the emitted radar signals and receive the reflected radar signals;
wherein, while the radar unit is transmitting the emitted radar signals and receiving the reflected radar signals, the ECU operates the scanning actuator to move the radar unit relative to the door;
wherein the ECU processes the received reflected radar signals to determine presence of the object adjacent to and exterior of the door;
wherein, responsive to determining presence of the object adjacent to and exterior of the door, the ECU operates the electrically powered actuator to control movement of the door relative to the vehicle;
wherein the radar unit is disposed in a handle of the door comprising a first handle end and a second handle end and being movable along a handle moving path; and
wherein a horizontal rotation axis extends along a surface of the vehicle and the handle is moved along the handle moving path by the scanning actuator rotating the handle and the radar unit about the horizontal rotation axis in a horizontal handle opening path between a handle closed position wherein the handle is angled relative to the door at a first horizontal handle rotation angle and a handle open position wherein the handle is angled relative to the door at a second horizontal handle rotation angle greater than the first horizontal handle rotation angle.
