Abstract: An engine control system in a vehicle including a variable displacement internal combustion engine, a speed sensor for detecting the speed of the variable displacement internal combustion engine, a controller for controlling the displacement of the variable displacement internal combustion engine, and where the controller varies the spark timing of the variable displacement engine based upon the detected speed during changes in the displacement of the variable displacement internal combustion engine.

Abstract: A method of controlling a cruise control system, comprising the steps of: assigning a low lateral acceleration limit; assigning a high lateral acceleration limit; determining a lateral acceleration of a vehicle; comparing the lateral acceleration to the low and high lateral acceleration limits; monitoring a torque command of a torque control computer at least where the lateral acceleration is above the low lateral acceleration limit; and compensating the torque command by setting the torque command equal to a minimum torque command where the lateral acceleration is between the low and high lateral acceleration limits and the torque command increases.
