Abstract:
A current control output (CCO) system for transmission solenoids includes a current determination module, a current compensation module, and a current control module. The current determination module determines a desired current for the solenoids based on a desired pressure. The current compensation module generates a compensated current by adjusting the desired current based on a system pressure and a temperature of oil in the transmission. The current control module performs current-based control of and applies hysteresis to the solenoids based on the compensated current.
