TRANSMISSION SENSING AND MEASUREMENT SYSTEM
First Claim
1. A sensing and measurement system for a transmission assembly, comprising:
- a bearing assembly having an outer ring, an inner ring, a plurality of roller bodies arranged between the outer ring and the inner ring, a first sensor arranged directly on one of the rings to collect data and a cable link fixed to and extending from the first sensor to transmit the collected data.

Abstract
A transmission sensing and measurement system. The system provides real-time feedback of various transmission operating characteristics which enables immediate synchronized shift calibration in response to vehicle operating conditions. The system can be applied to various transmission components and positions, such as bearing, shafts, and differentials. The system is arranged in a transmission assembly. By way of a method for measuring operating characteristics of the transmission where data is collected by a sensor and transmitted, optimal operating characteristics of the transmission can be calculated.

20. A method for measuring operating characteristics of a transmission, the method comprising:
-
assembling a bearing in a housing of the transmission, the bearing having an outer ring, an inner ring, a plurality of roller bodies arranged between the outer ring and the inner ring, a sensor arranged directly on one of the rings and a cable link fixed to and extending from the sensor to transmit data collected for review, analysis and adjustment of operating characteristics; measuring strain data on the bearing via the sensor; amplifying, filtering, and converting the data from analog to digital; transmitting the data collected to a transmission controller; and processing the data and calculating optimal operating characteristics by an algorithm resulting in forces, moments, and torque, which are transmitted on a network through a controller to the transmission.
