Vehicle control system

A system, comprising:

• one or more processors configured to:
• be coupled with a vehicle that is propelled by an electric drive system having one or more motors, the vehicle powered by one or more of a first electric energy from an off-board power source or a second electric energy from an onboard power source;
• detect whether the vehicle disconnects or begins disconnecting from the off-board power source while the vehicle is being powered by the first electric energy of the off-board power source;
• supplant the first electric energy of the off-board power source to the vehicle with an amount of the second electric energy of the onboard power source responsive to detecting the vehicle disconnects or begins disconnecting from the off-board power source,
• wherein the onboard power source includes an engine, the one or more processors configured to increase an engine speed of the engine to a designated speed responsive to detecting the vehicle disconnects or begins disconnecting from the off-board power source.

A system, comprising:

• a collector device coupled to a vehicle propelled by an electric drive system having one or more motors;
• a conductive pathway extending along a route being travelled by the vehicle, the conductive pathway configured to be selectively engageable with the collector device to provide a first electric energy to the electric drive system;
• and
• a controller configured to detect a disconnection of the vehicle from the conductive pathway while the electric drive system is being powered by the first electric energy, the controller configured to supplant a decreasing amount of the first electric energy from the collector device with an amount of a second electric energy supplied by an onboard power source to power the electric drive system responsive to the detection of the disconnection from the conductive pathway.
