An autonomous electric road vehicle is transported by a railcar for automated railed travel on a railway. During automated railed travel, the railcar is powered by the autonomous road vehicle's main power source and driven by the autonomous road vehicle's driving automation control system. A driver control of the autonomous electric road vehicle allows a human driver to apply emergency braking during both road and railed travel.

A power delivery system for an electric vehicle provides efficient power management for either continuous or intermittent high-performance operation, using a boost stage and an on-board charging circuit. A main battery, configured as a high-capacity power source, supplies power to the electric motor under normal load conditions. An auxiliary boost battery assists the main battery in supplying a high-level current at a higher discharge rate thereby causing the motor to operate in a high-performance drive mode. A charging circuit recharges the boost battery from the main battery during operation of the motor. The charging circuit also maintains a charge balance between the boost battery and the main battery when the two batteries have different chemistries. In one embodiment, participation of the boost battery in powering the electric motor can be controlled automatically according to sensed changes in the load. In another embodiment, power management can be based on timed intervals.

In one aspect, a controller for driving a motor of the present invention includes a driving control unit that controls driving of a motor, and a regenerative control unit that instructs the driving control unit to start regeneration when a signal from a pedal rotation sensor that detects a rotation direction of the pedal indicates that the rotation direction of the pedal is backwards, the regenerative control unit controlling an amount of the regeneration in accordance with a backward rotation amount of the pedal while the rotation direction of the pedal is backwards, the backward rotation amount being obtained by the pedal rotation sensor.
