Abstract:
A position detecting switch-combined electronic control unit for an automatic transmission, comprising:a base board having a plurality of elements disposed thereon, the plurality of elements including a microcomputer containing an automatic transmission control program;a position detecting switch having a detecting portion connected to the microcomputer;the position detecting switch and the base board disposed together within a case;the position detecting switch also having a rotor and a plurality of non-contact sensors provided on the base board, the plurality of non-contact sensors being disposed proximate to the rotor as the detecting portion for detecting rotation of the rotor;the microcomputer also containing a learning control program for calculating and correcting a positional deviation in a rotational angle of the rotor with respect to each of the plurality of non-contact sensors, on the basis of a signal from each sensor corresponding to the rotation of the rotor; andat least some of the plurality of elements disposed on the base board are arranged outside a range of rotation of the rotor.
