ABSTRACT:
An automotive cruise control system equipped with an actuator to regulate the state of an automobile in accordance with a control signal indicative of an actuator control amount so that the vehicle maintains a target speed, the actuator control amount being determined on the basis of the speed of the vehicle and the operation state of the actuator. The automotive cruise control system is arranged so as to divide the vehicle into first and second systems: the first system on-line-identifies a model corresponding to the state of the vehicle; the second system on-line-identifies a model corresponding to the actuator used in the vehicle. The actuator control amount is calculated on the basis of the first and second system models to produce the actuator control signal in correspondence with these models. By identifying two models, the time lag normally associated with this type of automotive cruise control system is reduced because this arrangement allows simplifying the identification of the model relating to the vehicle concurrently with realizing accurate control of the vehicle.
