1. A vehicle door system, comprising:

  • a vehicle structure including adjacent front and rear door openings;

    a front door having an edge comprising a front edge portion and a rear edge portion, wherein the front edge portion is rotatably mounted to the vehicle structure to close off the front door opening when the front door is in a closed position, the front door including a rear edge portion that is opposite the front edge portion;

    a front anti-pinch sensor that is configured to detect a hand positioned adjacent the front door opening alone, adjacent the edge of the front door alone, or adjacent the front door opening and the edge of the front door taken together;

    a front electrically-powered door actuator that moves the front door, wherein the electrically-powered door actuator can be actuated to partially open the front door by shifting the front door from a closed position to a partially open position to form a gap between the rear edge portion of the front door and the vehicle structure such that a user can grasp the rear edge portion and pull the front door to a fully open position, and wherein the front electrically-powered door actuator can be actuated to shift the front door from the fully open position towards the closed position;

    a rear door rotatably mounted to the vehicle structure to close off the rear door opening when the rear door is closed;

    a rear anti-pinch sensor;

    a rear electrically-powered door actuator that can be actuated to move the rear door to an open position;

    a controller configured to;

         1) cause the front electrically-powered door actuator to generate a force tending to prevent the front door from closing if the anti-pinch sensor detects a hand; and

         2) actuate the electrically-powered door actuator to shift the door from the fully open position towards the closed position; and

    wherein the controller is configured to cause the rear electrically-powered door actuator to generate a force tending to prevent closing of the rear door if the front anti-pinch sensor detects a hand.
