<P>PROBLEM TO BE SOLVED: To provide an automatic transmission controller which does not receive influence on detection of flowing current of an electromagnetic control valve due to a resistance component present between the ground and earth in such a structure that a ground on an electronic circuit board is shared by the electromagnetic control valve controlling a supply oil pressure to an automatic transmission and another electric device. <P>SOLUTION: The automatic transmission controller includes a microcomputer arranged on the electronic circuit board, calculates an energizing command value (a target control current value) to the electromagnetic control valve based on an oil pressure supply control value (a lateral pressure target value) of the automatic transmission (CVT), which is calculated based on the state of a vehicle, controls energization based on it (S10 to S12), detects the load of the electric device which shares the ground on the board with the electromagnetic control valve, and calculates the energizing command value based on the calculated oil pressure supply control value and the detected load (S14 to S18). <P>COPYRIGHT: (C)2013,JPO&INPIT |
