System and method for shifting the transfer case into and out of the neutral position using an electronic vehicle information center

摘要

A system for shifting a vehicle's transfer case into or out of the neutral position, using an electronic vehicle information center. The system comprises a transfer case control module connected to a transfer case and an electronic vehicle information center connected to the transfer case control module. The electronic vehicle information center instructs the transfer case control module to shift the transfer case into or out of the neutral position by detecting an input signal request from a control panel to shift the transfer case into or out of a neutral position, and sending an instruction signal to the transfer case control module to shift the transfer case into or out of the neutral position.

主权项

1. A system for shifting a vehicle's transfer case into or out of a neutral position, the system comprising:
a transfer case control module connected to a transfer case; and an electronic vehicle information center connected to the transfer case control module, the electronic vehicle information center instructing the transfer case control module to shift the transfer case into or out of the neutral position by:
detecting an ignition key being in a run position;detecting an input signal request to shift the transfer case into or out of the neutral position;determining whether predetermined conditions exist to allow the transfer case to be shifted into or out of the neutral position, the predetermined conditions including each of the engine being off, the brake pedal being applied, and the transmission being in neutral;sending an instruction signal to the transfer case control module to shift the transfer case into or out of the neutral position based on the detected input signal only when the predetermined conditions exist and the input signal requesting to shift the transfer case into or out of the neutral position was held for a plurality of seconds.
