Title:
AUTOMATIC TRANSMISSION CONTROLLER FOR AUTOMOBILE
Document Type and Number:
Japanese Patent JPS59155653
Kind Code:
A
Abstract:
PURPOSE:To make accurate control attainable according to loading capacity, by detecting the internal pressure of a shock absorber, while altering a gear-shift pattern in order to correspond to change in this pressure signal. CONSTITUTION:In this controller, a throttle sensor 20, detecting the opening of a throttle, each of car speed sensors 21 and 22 and a shift position sensor 23 are all installed, while a pressure sensor 26 detecting pressure inside a shock absorber is as well installed, and signals out of these sensors 20-23 and 26 are inputted into an electronic control unit 12. And, this controller outputs a gear- shifting control signal corresponding to a car speed signal and a load signal to an automatic transmission unit 11, while a gear-shift pattern is altered according to change in a pressure signal out of the pressure sensor 26. With this constitution, even if the turning angle of a suspension arm varies with those of level- controlling, etc., there is no influence to the pressure inside the shock absorber at all, therefore detection for accurate weight comes possible to be done so that accurate control according to the weight can be achieved.
