1 . A method of remotely updating control software in a heavy-duty vehicle having at least one programmed controller, the method comprising:
securing the heavy-duty vehicle;
determining that the vehicle is secured;
establishing a wireless connection with the heavy-duty vehicle;
downloading an updated control software; and,
updating the heavy-duty vehicle's control software with the updated control software in response to the determining that the vehicle is secured.
2 . The method of claim 1 , wherein the heavy-duty vehicle includes an electric drive system.
3 . The method of claim 1 , further comprising comparing an installed version of controller software with a later version of control software.
4 . The method of claim 3 , wherein the comparing the installed version of control software is initiated from onboard the heavy-duty vehicle.
5 . The method of claim 3 , wherein the comparing the installed version of control software is initiated from offboard the heavy-duty vehicle.
6 . The method of claim 1 , wherein the securing the heavy-duty vehicle comprises physically securing the heavy-duty vehicle.
7 . The method of claim 1 , wherein the determining that the heavy-duty vehicle is secured comprises receiving a primary indication that the vehicle is secured.
8 . The method of claim 1 , wherein the determining that the heavy-duty vehicle is secured comprises receiving a secondary indication, which is associated with a condition of the vehicle that is also associated with the vehicle being secured.
9 . The method of claim 8 , wherein the secondary indication comprises a location of the heavy-duty vehicle; and,
wherein the determining that the heavy-duty vehicle is secured is based on the location of the heavy-duty vehicle.
10 . The method of claim 8 , wherein the secondary indication comprises a state or an activity associated with the vehicle being shut down.
11 . The method of claim 10 , wherein the state or the activity associated with the vehicle being shut down comprises a time or a date information associated with the vehicle being out-of-service.
12 . The method of claim 10 , wherein the state or the activity associated with the vehicle being shut down comprises an override information associated with the vehicle being serviced.
13 . The method of claim 8 , wherein the secondary indication comprises a state or an activity associated with the vehicle being detained.
14 . The method of claim 13 , wherein the state or the activity associated with the vehicle being detained comprises a refueling information.
15 . The method of claim 1 , wherein the establishing the wireless connection with the heavy-duty vehicle comprises establishing the wireless connection with an access point communicatively coupled to the Internet.
16 . The method of claim 1 , wherein the downloading the updated control software and the updating the heavy-duty vehicle's control software are substantially the same function.
17 . The method of claim 1 , wherein the downloading the updated control software further comprises receiving and storing a latest version of control software prior to the determining that the vehicle is secured.
18 . The method of claim 1 , wherein the downloading the updated control software comprises confirming the integrity of the updated control software transmission.
19 . The method of claim 1 , wherein the updating the heavy-duty vehicle's control software comprises confirming the integrity of the updated control software.
20 . The method of claim 1 , wherein the downloading the updated control software comprises downloading the updated control software via a central controller different from the at least one programmed controller; and,
wherein the updating the heavy-duty vehicle's control software comprises the central controller configuring the at least one programmed controller to receive the updated control software.
21 . The method of claim 1 , further comprising limiting functionality of the heavy-duty vehicle during the updating the heavy-duty vehicle's control software.
22 . A control software updating device in a heavy-duty vehicle having at least one programmed controller, the control software updating device comprising:
means for determining that the heavy-duty vehicle is secured;
a wireless communication module configured to receive an updated control software;
a processor configured to update control software in the at least one programmed controller responsive to determining that the heavy-duty vehicle is secured.
23 . A system for remotely updating control software in a heavy-duty vehicle having at least one programmed controller, the system comprising:
an indicator configured to indicate that the heavy-duty vehicle is secured;
a server configured to provide updated software;
a wireless communication link between the heavy-duty vehicle and the server, the wireless communication link configured to communicate the updated software from the server to the heavy-duty vehicle;
a processor configured to update the heavy-duty vehicle's control programming using data transmitted from the server across the wireless communication link when the heavy-duty vehicle is secured.
24 . The system of claim 23 , wherein the wireless communication link between the heavy-duty vehicle and the server includes an intermediate network comprising at least a WLAN and Internet.
25 . The system of claim 23 , wherein the at least one programmed controller includes the processor.
26 . The system of claim 25 , further including a telemetry system controller other than the at least one programmed controller including the processor.
