Abstract

A system and method for controlling a vehicle to implement an engine torque management strategy. The engine torque management strategy implements a sophisticated engine knock control method that alleviates/mitigates the cause of the knock while also optimizing vehicle performance and engine efficiency without compromising engine hardware protection. Whenever suitable, the system and method attempt to reduce the amount of air trapped in a knocking cylinder to reduce its effective compression ratio and to eliminate the knock while keeping the same optimal spark timing for combustion efficiency.
