摘要： The control system governs the operation of a vehicle along the right-of-way which is divided into a plurality of zones and has control means for governing safe operation of the vehicles in accordance with traffic conditions. The improvement comprises means on the vehicle for demarcating the ends thereof and wayside located check-in means at entering boundaries of each zone responsive to the passage of the front end of the vehicle which provides the check-in signal. Wayside located check-out means beyond the check-in means at exit boundaries of each zone providing an overlap zone between zone boundaries, and is responsive to the passage of the rear end of the vehicle. The check-in marker provides the check-out signal while clearing the previous zone only provided the check-in signal is received. A speed selector is located in the overlap zone enabled by the check-in signal for communicating a selected speed limit to the vehicle only within each of said overlap zones.

摘要： An automatic vehicle control system for controlling the operation of a vehicle from a set of parallel operating computers in a central control station. A data communication link transmits vehicle performance reports from the vehicle to the central control station and transmits vehicle command messages from the central control station to the vehicle. Validating circuitry in the vehicle validates received vehicle command messages by verifying the messages originated from both computers in the central control station. A portion of the vehicle command message included in the vehicle performance report is subsequently used by the two computers to validate the performance report message transmitted from the vehicle to the central control station.
