The door is moved at a relatively slow speed for a predetermined initial time period and after the predetermined initial time period has ended the door is moved at a relatively faster speed.

主权项

1. A system for motorizing movement of at least one door of a vehicle relative to a door frame of the vehicle, the vehicle having a vehicle power supply to provide vehicle power, the system comprising:
an electric drive system coupled at least in part to the door frame and one of the doors of the vehicle, wherein the electric drive system moves the door between a closed door position and an open door position; a local power source different from the vehicle power supply, wherein the local power source is coupled at least in part with the electric drive system to allow for movement of the door between the closed door position and the open door position independent of the vehicle power supply, wherein the local power source has priority over the vehicle power supply to provide power to the electric drive system when moving the door between the closed door position and the open door position; and a controller coupled at least in part with the electric drive system, wherein the controller is coupled at least in part with the local power source such that the controller manages the local power source, and wherein the controller determines when a predetermined amount of vehicle power is available to recharge the local power source.
