VEHICLE MAXIMUM SPEED LIMITER BYPASS SYSTEM

Abstract:

Systems and methods for dynamically limiting the road speed of a vehicle are provided herein. The method includes limiting the speed of the vehicle to a predetermined first speed under normal operating conditions. The method further includes selectively engaging an override condition for an activation interval responsive to an operator generated input. The override condition may be limited to a determined number of times in an activation assessment interval. During an activation interval of the override condition, the vehicle can exceed the predetermined first speed by a specified offset that defines a second speed greater than the first speed. The activation interval may be a period of time or a distance. The override condition is not available when the number of activations in the activation assessment interval exceeds a threshold value. The activation assessment interval may be defined by a period of time, a distance, an event or action, etc.
