AISIN AW has developed a new transmission control module (hereinafter referred to as “TCM”), which can be applied to the world wide FWD 6-speed automatic transmission (hereinafter referred to as “A/T”). This newly developed TCM can contribute to the whole vehicle system as it is integrated to mechanical A/T in the meaning of ‘hardware’, and completed and ensured the functions in the A/T system. This TCM allows us to greatly reduce the number of the wire harness and the connector, and the space for installing TCM, which are required for the conventional style: A/T and TCM are separately installed, so that it can contribute to fuel economy, weight saving, utilization of the space in the engine room and cost reduction.Our Integrated TCM on A/T integrates the functions with the conventional neutral safety switch (hereinafter referred to as “N.S.S/W”) for detecting shift position, so that it allows compact installation to the limited space on A/T. Also, we have tried to ensure miniaturization and improvement of the durability for detecting shift position by replacing the conventional mechanical contact type N.S.S/W with the contact less position sensor.This TCM ensures the high reliability under the severe condition of direct installation on A/T by introducing the ceramic multilayer board, integrating the interface circuit exclusively for A/T, and applying the chip size package technology to the micro controller and IC.
