Publication number: 20250115231Abstract: Model-based predictive control (MPC) of a motor vehicle involves an MPC algorithm, which comprises a high level solver module to calculate a high level longitudinal trajectory for an upcoming route segment, according to which the motor vehicle is to travel within a route-based high level prediction horizon. The high level longitudinal trajectory is sent to a tracker solver module in the MPC algorithm as an input value, which calculates a tracker longitudinal trajectory on the basis of the high level longitudinal trajectory, according to which the motor vehicle is to travel within the time-based tracker prediction horizon, wherein the tracker prediction horizon is shorter than the high level prediction horizon, such that the tracker prediction horizon only covers a portion of the high level prediction horizon.Type: ApplicationFiled: September 3, 2021Publication date: April 10, 2025Applicant: ZF Friedrichshshafen AGInventors: Timo Wehlen, Timon Busse, Valerie Engel, Lorenz Fischer, Matthias Zink, Julia Stecher, Lothar Kiltz, Andreas Wendzel, Vasilis Lefkopoulos, Joachim Ferreau

Patent number: 12233884Abstract: A processor unit (3) is configured for executing an MPC algorithm (13) for model predictive control of a first component (18) of a motor vehicle (1) and of a second component (19) of the motor vehicle (1). The MPC algorithm (13) includes a cost function (15) to be minimized and a dynamic model (14) of the motor vehicle (1). The dynamic model (14) includes a loss model (27) of the motor vehicle (1). The loss model (27) describes an overall loss of the motor vehicle (1). The cost function (15) includes a first term, which represents the overall loss of the motor vehicle (1). The overall loss depends on a combination of operating values, which includes a first value of a first operating parameter and a second value of a second operating parameter. The processor unit (3) is also configured for determining, by executing the MPC algorithm (13) as a function of the loss model (14), that combination of operating values, by which the first term of the cost function (15) is minimized.Type: GrantFiled: November 14, 2019Date of Patent: February 25, 2025Assignee: ZF Friedrichshafen AGInventors: Timon Busse, Matthias Friedl, Timo Wehlen, Valerie Engel, Christian Baumann

Publication number: 20240351604Abstract: A method for model-based predictive control (MPC) of a motor vehicle includes executing an MPC algorithm having a high level solver module, a longitudinal dynamics model, and a cost function dedicated to the high level solver module. By executing the high level solver module for an upcoming route segment while taking the longitudinal dynamics model into account, a speed trajectory is calculated that minimizes the cost function, according to which the motor vehicle is to travel within a prediction horizon. The method includes sending the speed trajectory to a human-machine interface as an input value, processing the speed trajectory to obtain a control signal in the human-machine interface, and outputting the control signal to a driver of the motor vehicle with the human-machine interface, such that the driver can control the motor vehicle in accordance with the control signal.Type: ApplicationFiled: September 30, 2021Publication date: October 24, 2024Applicant: ZF Friedrichshafen AGInventors: Timo Wehlen, Timon Busse, Valerie Engel, Lorenz Fischer, Matthias Zink, Raffael Selegrad, Andreas Wendzel
