Abstract

PURPOSE:To carry out accurate and stable control, by changing over the input signal range with a range changeover device if a change in an input signal of an image sensor with a shadow, etc., continues for a given period. CONSTITUTION:Steering control is carried out while sensing a boundary line with an image sensor 1. In the process, if an input signal of an image sensor is changed with a shadow, etc., and the change continues for a given period, the input signal range is automatically changed over with a range changeover device 2. The resultant signal within the regulated range is then passed through a comparator 3 and inputted to a control part, such as CPU.
