Abstract
Apparatus and a method for monitoring the performance of control algorithms, and inappropriate operator actions, and for providing failsafe deceleration for a vehicle, particularly an agricultural windrower, wherein the propulsion driveline of the vehicle is controllably and actively decelerated. Inappropriate operator actions can include, but are not limited to, attempted engagement of the park brake when operating in a high speed range. Control algorithm fault conditions can include, for instance, input commands changing at a rate beyond a predetermined threshold, and mismatch between operator control devices such as a FNR lever and a neutral switch.
