1. A gesture access and object impact avoidance system for a motor vehicle, comprising:

  • at least one radar signal transmitter configured to be mounted to the motor vehicle and responsive to activation thereof to emit radar signals,at least one radar signal receiver configured to be mounted to the motor vehicle and to produce radar detection signals, the radar detection signals including at least one reflected radar signal in response to detection by the at least one radar signal receiver of at least one of the emitted radar signals reflected by an object toward the at least one radar signal receiver,at least one processor operatively connected to the at least one radar transmitter and the at least one radar receiver, the at least one processor programmed to activate the at least one radar signal transmitter and to be operable in either of (i) a gesture access mode to control an actuator associated with an access closure of the motor vehicle to lock, unlock, open or close the access closure in response to an object within a sensing region of the at least one radar signal receiver exhibiting a predefined gesture, and (ii) an object impact avoidance mode to activate a warning device or control an actuator associated with an impact avoidance device of the motor vehicle in response to an object being within a predefined distance of the at least one radar signal receiver, andat least one memory having instructions stored therein executable by the at least one processor to cause the at least one processor to be responsive to the motor vehicle disabled from moving to operate in the gesture access mode, and to be responsive to the motor vehicle moving or enabled to move to operate in the object impact avoidance mode.
