ABSTRACT:
This invention is an electrical control apparatus for control of an automatic transmission in a motor vehicle. The electrical control apparatus includes an operator input device for generating a desired transmission state signal, an encoder for generating a present transmission state signal from the position of a mode select shaft on the transmission, and a logic control unit developing signals enabling a motor controller circuit to control operation of a motor which changes the state of the automatic transmission. The motor controller circuit is disposed remotely from the logic control unit, preferably in a power module which also includes the motor, and the encoder. This location of the motor controller circuit advantageously reduces the need for a high current wire harness, improves the dynamic braking efficiency, enhances serviceability, reduces the size of the part of the apparatus which must be mounted in the crowded instrument panel and reduces the effect of noise on the logic control unit.
