PURPOSE:To avoid failure or impossibility of the operation of a range control unit to be caused by over-current generated at the time of starting a direct current motor for driving a range switching valve. CONSTITUTION:In this automatic transmission control device, a direct current motor 34 for driving a range switching valve 30 of an automatic transmission is controlled electrically on the basis of the range switching signal output from a range control unit 20. A power source B2 of the direct current motor 34 and a power source B1 of the range control unit 20 are provided separately, and over-current breaking elements 61, 60 are provided respectively in circuits of both power sources B2, B1. |
