Traveling from Germany to Czech Republic and back by car

I am an American traveling through Europe. I recently lost my passport and am planning to go to Czech Republic from Germany in about a week by car(and back a week later). Will I be asked for my passport when I cross the border by car?

Edit: I have a scanned color copy of my passport I took before I lost it, not sure if it is of any use? I am going to get a police report today and have contacted the Embassy for emergency papers but they have not responded. I am wondering what will happen to me if I am trying to cross the border, will they just turn me down and not let me cross or will it be worse?

Update: The Munich US embassy is great, I emailed them around lunch time and explained my situation and they responded almost immediately and said I should come to the Embassy next day with the forms filled out. When I arrived I was allowed to cut everyone in line because I was American and they even had a passport photo machine at the embassy. I arrived around 9:30Am and had a new replacement passport by lunch time.

Since both countries belong to the Schengen Area, there is no regular passport control at the border, but there may be controls at random. Due to the recent refugee discussion those random controls have been increased.
