Abstract: A vehicular control system includes an electronic control unit (ECU) disposed at a vehicle. The ECU includes electronic circuitry and associated software. The electronic circuitry of the ECU is operable to receive transmissions and to transmit signals. The vehicular control system, responsive to receiving at the ECU at least one transmission indicative of one or more mobile devices at an interior cabin of the vehicle, determines location of the one or more mobile devices at the interior cabin of the vehicle. Responsive to determination that a determined mobile device is located at a driver seat region of the interior cabin of the vehicle, and responsive to determination that the vehicle is moving at a speed above a threshold speed, the vehicular control system transmits a blocking signal to at least partially disable operation of the determined mobile device located at the driver seat region of the interior cabin.
