Title: DYNAMIC ELECTRIC DRIVE CONTROL
Abstract:
A Light Electric Vehicle (LEV) (10, 20) includes two motors (24a, 24b) and independent control of each motor. The two motors have different drive ratios (for example, gearing (26) or pulley/sprocket (28) ratios) or different efficiency versus RPM curves and are controlled to provide efficient operation over a wider speed range than possible with a single motor or two motors having the same efficiency at any given vehicle speed.
