Abstract

PURPOSE:To facilitate steering control by storing pieces of information on the operation of a steering device and a controller in a storage device, and outputting an automatic steering and a turning command by performing reading from and writing to the storage device by plural sensor signals. CONSTITUTION:When a switch 82 is placed at an automatic side and a switch 81 is set at a writing side, a data processor 6 executes a program for teaching stored in a memory 60, and when at a reading side, it executes a program for reproduction. Output signals A, B, and C from sensors 1a, 1b and 1c are supplied to a signal processing circuit 3 for subtraction processing of A-B and B-C, and their difference P=(A-B)-(B-C) is also found to obtain the extent of deviation of a steering sensor from a boundary line INT as a profile guide for automatic steering by said value P. The signals A and C are used for switching from automatic steering to automatic sweeping, and the value A-C found by the circuit 3 is compared with a reference value Th, outputting a high-level signal when the Th is greater.
