Electrical steer-by-wire steering system for e.g. fork-lift truck, has electronic control device designed such that position of steering transmitter in operating mode provides desired value for steering position of guided wheel

摘要

The system has an electronic control device (5) staying in effective connection with a steering transmitter sensor (3) i.e. potentiometeric sensor, a wheel sensor (11) and an electrical steering motor (7). The device is designed such that position of a steering transmitter (1) in an operating mode provides a desired value for a steering position of a guided wheel (9). The motor is controlled such that difference between an actual value of the steering position and a reference value is smaller. A steering movement of the wheel is coupled to movement of the transmitter.
