PARKING PAWL ENGAGEMENT CONTROL WITH FEEDBACK

摘要

PROBLEM TO BE SOLVED: To provide a system and method for improving the consistency of a hybrid vehicle parking pawl engagement control.SOLUTION: A hybrid vehicle includes a motor-generator, a planetary gear, a parking pawl, and a processor. The hybrid vehicle uses feedback to more accurately determine that the parking pawl is fully engaged. The parking pawl is applied to the planetary gear. The processor determines a target movement for the hybrid vehicle and commands a torque from the motor-generator to achieve the target movement. The processor determines that the parking pawl has fully engaged and locked the planetary gear.
