Abstract
A grade control system for a motor grader configured to adjust the speed of the motor grader based on a difference between a desired grade and a current grade. The difference between the desired grade and the current grade provides a current error signal which is compared to a predetermined acceptable error signal or a predetermined range of acceptable error signals. If the current error signal is outside the range of acceptable error signals, the vehicle is automatically slowed down. If the vehicle is within the range of acceptable error signals, the vehicle speed either remains the same or the vehicle speed is increased to improve productivity, while maintaining the current error signal within the range of acceptable error signals. The desired grade is provided to an electronic control unit resident on the grader from either a 2D cross slope machine control system or a 3D machine control system.
