Keying check apparatus is provided for a control system including at least two microprocessor cradles, with each microprocessor cradle having a unique control program, and which keying check apparatus determines through operation with one of a first and second interrupt that the desired control program and the correct connections are provided for the CPU board of each microprocessor cradle.

Electronic key check for ensuring proper cradles insertion by respective

A programmed microprocessor motor control apparatus is provided for a vehicle propulsion motor that is responsive to an input control device to determine the acceleration rate and a predetermined motor voltage curve of the propulsion motor.

Motor control chopper apparatus phase angle limiting

The propulsion control apparatus for a vehicle including a plurality of motor driven wheel units detects a slip or slide operation of at least one wheel unit in accordance with a predetermined difference between sensed motor currents, and reduces the tractive effort of those wheel units until the sensed motor currents no longer have that difference.
