Project to auto roll up a car window.
I would like to achieve the following functions using Arduino Uno.
Whenever UP SWITCH is pulled up, the window should roll up automatically regardless of whether the switch is still on hold or released.
As the window rise up, any resistance or object hindering on its way is encountered, the window rolling should be shut off instantly.
Any extra sensors like current sensor, etc., necessary would be always welcome.
Thanks.

Thanks forum.
This can cause a lot of legal problems if somebody gets caught in the window. You will need to sense window position, possibly torque, etc. Note as the temperature changes so do the motor and mechanical properties change. Then you get to solve load dump problems etc, A car is one of the worse electrical environments work in. I highly recommend a different project.
I answered this in one of your other posts. Had I known you were posting it more then once I would have not answered it. I have more to do with my time then burn it on redundant/duplicate questions. You just cost somebody else a critical answer.
I've merged your cross-posts @tonsing.
Cross-posting is against the rules of the forum. The reason is that duplicate posts can waste the time of the people trying to help. Someone might spend 15 minutes (or more) writing a detailed answer on this topic, without knowing that someone else already did the same in the other topic.
Repeated cross-posting will result in a suspension from the forum.
In the future, please take some time to pick the forum board that best suits the topic of your question and then only post once to that forum board. This is basic forum etiquette, as explained in the sticky "How to use this forum - please read." post you will find at the top of every forum board. It contains a lot of other useful information. Please read it.
Thanks in advance for your cooperation.
"2. As the window rise up, any resistance or object hindering on its way is encountered, the window rolling should be shut off instantly."
That is the part you will need to figure out first, and it probably will not be simple.
This is why the "auto" function only appears on the driver's window.
(Why? It is assumed the driver is competent!)

NO...
All electric window actions in the UP direction should BE DEADMAN SWITCH operation.
Any sort of monitoring to prevent crushing an obstruction only makes for complexity and hence more to fail.
I know its from Wiki, but;
Power windows have come under some scrutiny after several fatal accidents in which children's necks have become trapped, leading to suffocation. Some designs place the switch in a location on a hand rest where it can be accidentally triggered by a child climbing to place his or her head out of the window. To prevent this, many vehicles feature a driver-controlled lockout switch, preventing rear-seat passengers (usually smaller children) from accidentally triggering the switches. This also prevents children from playing with them and pets riding with their heads out windows from activating the power window switch.
Starting with the 2008 model year, U.S. government regulations required automakers to install safety mechanisms to improve child safety.[12] However, the rules do not prevent all potential injuries to a hand, finger, or even a child's head, if someone deliberately holds the switch when the window is closing. In 2009, the U.S. auto safety administration tentatively decided against requiring all cars to have automatic reversing power windows if they sense an obstruction while closing.[13] Proposed requirements concern automatic ("one-touch up") window systems, but most vehicles with this feature already have automatic-reversing.[14] The federal government made a written contract that all automakers should make the lever switches (as opposed to the rocker and toggle switches) standard on all new vehicles by 1 October 2010.[15]
" In 2009, the U.S. auto safety administration tentatively decided against requiring all cars to have automatic reversing power windows if they sense an obstruction while closing."
I wonder why?

Tom... 
The problem of course with obstruction sensing is that it simply will not work (in practice). Sad perhaps, but true.
