Embodiment Construction

[0017] The following description relates to systems and methods for determining an optimal torque distribution for a given vehicle with a known amount of disturbance along a route. A model predictive control problem is formulated to determine optimal engine torque by minimizing vehicle fuel consumption over a time domain. figure 1 An example engine system of a vehicle is shown. figure 2 An example configuration of a vehicle driveline is shown. exist image 3 The block diagram shown in shows an MPC problem constructed from the input and output of an example vehicle model. Figure 4 An example method for determining optimal engine torque to minimize fuel consumption is shown. Figure 5A and Figure 5B The effect of the length of the time domain on the convergence of the MPC solution to the optimal solution is shown.

Abstract

Method and system are provided for vehicle route planning based on adaptive model predictive control. In one example, a method may include real-time online identification of the vehicle model base on the vehicle inputs and outputs; compression of the input space to increase the optimization efficiency; and optimization of the route planning based on the model parameter of the vehicle and the known road grade.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Patent Application No. 62 / 058,851, entitled "Efficient Adaptive Model Predictive Control for Optimal Vehicle Route Planning (EFFICIENT ADAPTIVE MODEL REDICATIVE CONTROLFOROPTIMALVEHICLER OUTEPLANNING)," filed October 2, 2014, for all purposes by This reference is hereby incorporated in its entirety. technical field [0003] The present description generally relates to methods and systems for vehicle routing planning. Background technique [0004] In advanced route planning, given known disturbances along the route, such as road gradient, traffic, etc., the optimal velocity distribution of vehicles can be calculated. The computation of the optimal speed profile can be formulated as a model predictive control (MPC) problem, where instead of computing the overall speed profile for the total route, the route can be decomposed into time domains of seconds or minutes. In...
