Abstract

PURPOSE:To improve the stability of steering control and the comfortableness of drive by automatically adjusting horizontal correcting ability of a titled device by learning control. CONSTITUTION:A microcomputer to be a control center for an automatic steering device consists of a CPU31, an ROM32 storing a control program, an RAM 33 temporally storing various data, an I/O interface 34, etc. The microcomputer 4 controls ON/OFF operation of switching circuits 67l, 67r, namely, excitation/ unexitation of solenoides VSl, VSr in accordance with the combination of ON and OFF of switches 221-225. The horizontal correcting ability by the solenoides VSl, VSr is automatically adjusted by a titled device by learning control.
