Patent number: 9658119Abstract: A system and method for detecting an erratic state of a monitored sensor includes generating a variation value for a monitored signal generated by a monitored sensor and a variation value for an estimated signal estimated based on a predictive signal generated by predictive sensor, where the predictive signal is predictive of the monitored signal. The monitored signal can rapidly fluctuate based on system operating conditions. A dynamic threshold value is generated based on the estimated variation value, and the monitored signal is compared with the dynamic threshold value to determine if the monitored signal is in an erratic state. The detection method is sufficiently sensitive to distinguish between rapid fluctuation of the monitored sensor and an erratic state.Type: GrantFiled: March 11, 2014Date of Patent: May 23, 2017Assignee: GM Global Technology Operations LLCInventors: David S.

Patent number: 9651132Abstract: A cast aluminum differential housing for a motor vehicle powertrain having cast iron inserts. The housing is cast of light weight aluminum which weighs approximately one-third that of iron which has formerly been used to fabricate such housings. At locations of significant loads and wear, such as the mountings for the stub shaft associated with the two idler bevel gears, iron inserts are cast into the housing. The housing thus weighs significantly less than a comparable iron differential housing but since the two significant wear and load bearing regions include cast iron inserts, the aluminum differential housing of the present invention has the ruggedness, durability and service life of the much heavier iron housing.Type: GrantFiled: September 9, 2015Date of Patent: May 16, 2017Assignee: GM Global Technology Operations, LLCInventors: Mahesh Annasaheb Mummigatti, Sachin Chandrakant Pagare
