Method for operating a battery-operated electric vehicle

摘要

The method for operating a pulse-controlled, battery-operated electric vehicle has an electric or hydraulic servo power steering system (11, 12), the electric motor (12) for the servo power steering being driven essentially by the differential voltage of the voltage required for the travel motor (10) in relation to the full operating voltage. A comparator (22) measures the voltage prevailing at the travel motor (10) and when a limit value of this voltage is exceeded it causes a relay (20) to actuate a switch (18) in such a way that the low voltage pole of the electric motor (12) for the steering is switched to a defined intermediate voltage value. In this way, it is ensured that the vehicle is fully steerable even when accelerating. <IMAGE>
