What do you mean by vehicle status?

If you mean speed, you can do the following:

1. Detect when the user is in a Vehicle using ActivityRecognition to DetectActivity
2. As soon as you detect the user is moving in a vehicle, keep a track of the Location and Time.
3. Whenever you find a new location, calculate the distance between the last location and the new one using distanceTo(Location). Also calculate the time difference. Your speed at this point will be distance / time.

You can keep repeating this for every new location you find and you will have the speed of the vehicle. You can read more about Android LocationStrategies.
