1. A motor vehicle that is mandated by law or regulation to stop at a railroad crossing before proceeding across the crossing, the vehicle comprising:
a body having an interior with a driver’s seat at a front of the body on one side and an entrance and exit door on the other side opposite the driver’s seat;
a power actuator for opening and closing the door;
lamps on the exterior of the body that are visible to other vehicles in the vicinity of the vehicle;
one or more accessories that generate sound that can be heard by a driver in the seat;
an electrical system comprising an electrical system controller (ESC) that processes data from various sources to provide control data for performing certain control functions incidental to operation of the vehicle;
a devoted switch accessible to a driver in the seat for signaling the ESC to initiate a sequence of operations when actuated by a driver upon the vehicle approaching a railroad crossing;
virtual controllers in the ESC that control the power actuator for the door, the lamps, and the one or more accessories, and that are responsive to actuation of the devoted switch by a driver a) to begin flashing the lamps, b) to mute the sound from the accessories, c) upon the ESC’s receipt of data indicating that the vehicle has stopped, to operate the power actuator to open the door, d) upon subsequent receipt of data disclosing that the vehicle has begun to move forward, operating the power actuator to close the door, e) unmuting the muted accessories, and f) ceasing flashing the lamps.
2. A motor vehicle as set forth in claim 1 in which the one or more accessories comprises a speaker of an audio system.
3. A motor vehicle as set forth in claim 1 in which the one or more accessories comprises a motorized blower of an air circulation system.
4. A motor vehicle as set forth in claim 1 in which the data disclosing that the vehicle has begun to move comprises vehicle speed data defining a selected speed.
5. A motor vehicle as set forth in claim 1 in which the data disclosing that the vehicle has begun to move comprises vehicle travel data disclosing a selected distance that the vehicle has traveled after the stop.
6. A motor vehicle as set forth in claim 1 including an additional input device for the ESC that is disposed for operation by a driver to extend the selected distance for allowing the vehicle to cross a longer crossing than a cross contemplated by the selected distance.
7. A method for performing a sequence of certain functions in a motor vehicle that is mandated by law or regulation to stop at a railroad crossing before proceeding across the crossing and that comprises a body having an interior driver’s seat that is disposed at the front of the body to one side and an entrance and exit door on the other side opposite the driver’s seat, a power actuator for opening and closing the door, lamps on the exterior of the body that are visible to other vehicles in the vicinity of the vehicle, one or more accessories that generate sound that can be heard by a driver, and an electrical system comprising an electrical system controller (ESC) that processes data from various sources to provide control data for performing certain control functions incidental to operation of the vehicle;
the method comprising:
providing a devoted switch for actuation by a driver occupying the seat upon the vehicle approaching a railroad crossing to signal the ESC to initiate a sequence of operations;
causing the ESC to respond to actuation of the devoted switch by causing a) the lamps to begin flashing, b) sound from the accessories to be muted, c) upon the ESC’s receipt of data indicating that the vehicle has stopped, the power actuator to open the door, d) upon subsequent receipt of data disclosing that the vehicle has begun to move forward, the power actuator to close the door, e) the muted accessories to be unmuted, and f) flashing the lamps to cease.
8. A method as set forth in claim 7 in which the one or more accessories comprises a speaker of an audio system.
9. A method as set forth in claim 7 in which the one or more accessories comprises a motorized blower of an air circulation system.
10. A method as set forth in claim 7 in which the data disclosing that the vehicle has begun to move comprises vehicle speed data defining a selected speed.
11. A method as set forth in claim 1 in which the data disclosing that the vehicle has begun to move comprises vehicle travel data disclosing a selected distance that the vehicle has traveled after the stop.
12. A method as set forth in claim 7 including providing an additional input device for the ESC that is disposed for operation by a driver and using the additional input device to extend the selected distance for allowing the vehicle to cross a longer crossing than a crossing contemplated by the selected distance.
13. A method as set forth in claim 8 including playing a prerecorded announcement over the speaker upon actuation of the devoted switch to request passengers to be quiet so that the driver can listen for a train.
