  • Technologies for optimal vehicle platooning control over steep terrain
    Patent number: 12682761
    Abstract: Technologies for platooned include a leader vehicle and one or more follower vehicles each including a computing device. The leader vehicle computing device controls velocity of the leader vehicle within a predetermined route based on a grade profile of the predetermined route. The leader vehicle may perform nonlinear model predictive control using a cost function based on predicted velocity error and predicted fuel consumption. The follower vehicle computing device controls velocity of the follower vehicle within the predetermined route based on headway distance to the leader vehicle and the grade profile. The follower vehicle may perform nonlinear model predictive control using a cost function based on predicted headway error, predicted headway rate of change, and predicted fuel consumption. Other embodiments are described and claimed.
