Methods and systems for cruise control velocity tracking

Abstract

Methods and systems are provided for cruise control velocity tracking. In one example, the method or system may generate a torque command output via a velocity controller that allows for an error within bounds to reduce a fuel consumption amount, the torque command output selected from outcomes of a leader and follower game.

Description

technical field [0001] The present description generally relates to methods and systems for controlling vehicle torque output for energy efficient cruise control. Background technique [0002] A standard cruise controller attempts to maintain the vehicle's speed at a set point speed. Typically, cruise controllers use tracking errors based on setpoint speed and current vehicle speed to determine desired wheel torque. However, maintaining the vehicle's speed at the set point speed may result in increased fuel consumption due to large variations in torque demand to maintain the vehicle's speed at the set point speed. [0003] Other attempts to address the problems associated with excess fuel consumption in cruise control mode include adapting multiple vehicle models to a non-linear model predictive control procedure. One such exemplary method is shown by D'Amato et al. in US Patent No. 9,849,880. Wherein the vehicle dynamics model and the vehicle fuel consumption model are a...

Problems solved by technology

[0006] In one example, the above problems may be addressed by a method for generating a torque command output via a speed controller, the torque command output being within tolerance tolerances to reduce fuel consumption, the torque command output being selected from a master slave Results of countermeasures (leader and follower game) (similar problems may be faced in the hierarchy)
