Abstract

The battery energized electric motor vehicle has a main driving motor connected to the battery via a footpedal operated control circuit; an auxiliary electric motor for a steering device is connected to the battery in series with the main driving motor and across the control circuit of the latter so that a difference voltage between the battery voltage and the instant driving voltage applied to the main driving motor controls the steering device.
