Abstract
A current regulator for a dc electric traction motor propelled vehicle, implemented using a microcomputer, incorporates an accelerator response characteristics of an accelerator in an internal combustion engine powered vehicle. The regulator uses a current feedback loop to regulate motor torque to the value called for by the accelerator. However, of the magnitude of voltage as a percentage of available source voltage required to generate the desired current exceeds the percentage displacement of the accelerator, the applied voltage is limited to the percent accelerator displacement.
