System and method for ensuring safe pull away of a vehicle from connected infrastructure

An article of manufacture, comprising:

• a non-transitory computer storage medium having a computer program encoded thereon that when executed by a controller inhibits movement of a vehicle away from infrastructure temporarily connected with the vehicle, the computer program including code for,
• receiving an infrastructure connection signal indicative of whether the vehicle is connected with the infrastructure or unconnected with the infrastructure;
• receiving a parking brake status signal indicative of whether a parking brake on the vehicle is in an applied state or a released state;
• receiving a vehicle speed signal indicative of a speed of the vehicle;
• determining whether the vehicle is in (i) an armed state permitting application of a service brake on the vehicle when a set of conditions is present in which the parking brake status signal indicates that the parking brake is in the released state, the speed of the vehicle meets a first predetermined condition relative to a threshold speed, and the infrastructure connection signal indicates the vehicle is connected with the infrastructure or (ii) a disarmed state prohibiting application of the service brake when the set of conditions is present;
• determining whether the set of conditions is present;
• and,
• directing, when the vehicle is in the armed state and the set of conditions is present, a valve to assume a first state in which the valve causes application of the service brake.
