Variable operation of vehicle transmissions using rough road sensing

Variable operation of vehicle transmissions using rough road sensing

A method for variable operation of a vehicle transmission using rough road sensing includes defining a first set of parameters to calibrate the vehicle transmission for a smooth road condition and a second set of parameters to calibrate the vehicle transmission for a rough road condition. The method...

description A method for variable operation of a vehicle transmission using rough road sensing includes defining a first set of parameters to calibrate the vehicle transmission for a smooth road condition and a second set of parameters to calibrate the vehicle transmission for a rough road condition. The method includes sensing a road condition, generating a road condition signal corresponding to the road condition, and measuring a magnitude of the road condition signal. The method includes switching from the first set of parameters to the second set of parameters to operate the vehicle transmission when the magnitude of the road condition signal exceeds a first predetermined threshold. The method includes switching from the second set of parameters to the first set of parameters to operate the vehicle transmission when the magnitude of the road condition signal is less than a second predetermined threshold that is different than the first predetermined threshold.
