System and method for detecting lash in a transmission and controlling an engine and/or a motor based on lash detections

摘要

A control system for a transmission of a vehicle includes a first angular rotation module, a second angular rotation module, and a lash module. The first angular rotation module determines a first angular rotation of a first shaft during a first predetermined period based on a first signal generated by a first shaft sensor. The second angular rotation module determines a second angular rotation of a second shaft during the first predetermined period based on a second signal generated by a second shaft sensor. The lash module selectively detects lash between gears of the transmission based on the first angular rotation and the second angular rotation.

1. A control system for a transmission of a vehicle, comprising:
a first angular rotation module that determines a first angle through which a first shaft on an input side of the transmission rotates during a first predetermined period based on a first signal generated by a first shaft sensor; a second angular rotation module that determines a second angle through which a second shaft on an output side of the transmission rotates during the first predetermined period based on a second signal generated by a second shaft sensor; a lash module that selectively detects lash between gears of the transmission based on the first angle and the second angle; and an engine control module that adjusts a desired transmission input torque based on whether lash is detected.
