Full titles differ between systems:

IPC:

Methods, circuits or devices for controlling the propulsion of electrically-propelled vehicles, e.g. their traction-motor speed, to achieve a desired performance; Adaptation of control equipment on electrically-propelled vehicles for remote actuation from a stationary place, from alternative parts of the vehicle or from alternative vehicles of the same vehicle train > for control of the vehicle or its driving motor to achieve a desired performance, e.g. speed, torque, programmed variation of speed

CPC:

Methods, circuits, or devices for controlling the traction-motor speed of electrically-propelled vehicles > for control of the vehicle or its driving motor to achieve a desired performance, e.g. speed, torque, programmed variation of speed

CPC subdivides this area 2x more granularly than IPC with 7 additional codes.

7 codes are CPC-only extensions.
