Method for deploying a torque reduction and torque limitation command through per wheel torque control of a controllable 4-wheel-drive system

摘要

A method for deploying torque commands from a vehicle stability assist control system to a four wheel drive system in a vehicle that includes utilizing a firewall within a four wheel drive system electronic control unit to analyze commands sent from a vehicle stability assist electronic control unit to the four wheel drive electronic control unit. Additionally, the commands from the vehicle stability assist electronic control unit, when the vehicle control system is in operation, are integrated with commands independently generated by the four wheel drive electronic control unit, and resultant wheel torque commands are generated to be provided to each individual wheel in the four wheel drive system.
