1. In apparatus for determining the program stop velocity of a passenger vehicle moving along a track and in response to vehicle track provided control signals establishing successive actual locations of that vehicle moving along said track in relation to controlling the vehicle movement in relation to a desired stopping position in accordance with a provided distance versus velocity relationship, the combination of:
- first means coupled with the vehicle for sensing the actual velocity of the vehicle,second means including signal receiver apparatus and responsive to said control signal for determining the remaining travel distance for said vehicle to reach said desired position for each said location,third means responsive to the actual velocity of the vehicle to provide for said vehicle a first desired program stop control velocity for said remaining travel distance in relation to the present time and in accordance with a first established desired relationship with that travel distance,fourth means responsive to the actual velocity of the vehicle to provide for said vehicle a second desired program stop control velocity for said remaining travel distance in relation to a predetermined future time and in accordance with a second established desired relationship with that travel distance, andfifth means controlling the velocity of said vehicle in response to each of said first and second program stop velocities.

12. In a method of determining the program stop velocity of a vehicle moving along a track and in relation to a passenger station desired stopping position in accordance with track provided control signals indicating respective actual locations of that vehicle along said track as a function of said desired stopping position, the steps of:
-
determining the actual velocity of said vehicle, determining the remaining travel distance from each said actual location for said vehicle to reach said stopping position, determining a program stop desired control velocity for each said actual location as a function of the remaining travel distance from that location to said stopping position, determining a look-ahead desired control velocity for each said actual location as a function of the remaining travel distance from the location where the vehicle is anticipated to be after a predetermined future time period, and controlling the actual velocity of the vehicle in response to a predetermined comparison of said determined actual velocity with at least one of said program stop desired control velocity and said look-ahead desired control velocity. - View Dependent Claims (13, 14)
