Here's a possible software solution:

Measure the voltage drop across the main breaker with an analog input. Sample it and square each sample. Run the squared samples through a low-pass filter (a simple IIR would probably suffice). If the filtered value exceeds some experimentally-determined threshold, reduce the commands to the drive motors until the filtered value drops below the threshold.
