An open loop adaptive control system for improving the driveability of a vehicle having at least one air supply modulator such as a throttle. The control system generating a correction signal supplied to the air supply modulator wherein the correction signal when added to the operator commanded signal input to the air supply modulator is such as to cancel the speed and pressure variability of the engine and vehicle dynamics and substitute for these dynamics determinable vehicle control dynamics therein improving the driveability of the vehicle by establishing uniform performance.

In a vehicle powered by an internal combustion engine having a moveable throttle for determining the vehicle speed and a control linkage for setting the position of said throttle in response to operator commands, and a second throttle means for improving the driveability of the automobile, comprising: means providing a first signal indicative of the position of said throttle set by said control linkage; first multiplying means for multiplying said first signal by a factor which is determined by parameters of the vehicle and providing an output proportional to the product thereof; second multiplying means for multiplying the output of said first multiplying means by a factor which is constituted by the quotient of a variable indicative of vehicle speed divided by the manifold absolute pressure of the vehicle engine and providing an output proportional to the product thereof; means providing the difference between said first signal and the output of said second multiplying means; differentiating means providing an output proportional to the derivative with respect to time of said output of said difference means; control means responsive to the output of said differentiating means for modifying the last named output in accordance with the desired dynamics of the engine and vehicle; and means for positioning said second throttle in proportion to the output of said control means.
