Automatic steering system using signal quality information

摘要

An automatic steering system is provided with a first position sensor for generating a first position signal and a second position sensor for generating a second position signal. Both position signals are communicated to a controller having a memory. The controller is also supplied signal quality information about the quality of the position signals. The controller evaluates the position signals based on the signal quality information and weights the position signals accordingly to calculate the position of the vehicle and select the vehicle's target path. The target path is selected from several target paths and is the best that corresponds to the position of the vehicle. The controller then generates a steering signal that is communicated to a steering controller for steering the vehicle.
