System and method of vehicle operating condition management

摘要

A vehicle operating condition profile can be determined over a given route while also considering imposed constraints such as deviation from time targets, deviation from maximum governed speed limits, etc. Given current vehicle speed, engine state and transmission state, the present disclosure optimally manages the engine map and transmission to provide a recommended vehicle operating condition that optimizes fuel consumption in transitioning from one vehicle state to a target state. Exemplary embodiments provide for offline and online optimizations relative to fuel consumption. The benefit is increased freight efficiency in transporting cargo from source to destination by minimizing fuel consumption and maintaining drivability.

1. A vehicle operating condition management system comprising:
a communication module configured to transmit vehicle operating condition data for a vehicle; and a cycle efficiency management module coupled to the communication module, the cycle efficiency management module configured to: access an engine map of the vehicle, the engine map including data corresponding to an engine speed and engine torque for the engine of the vehicle; predetermine a velocity profile to minimize fuel consumption of the vehicle for a route from a source to a destination, the velocity profile predetermined at least in part based on the accessed engine map and a determination of a transition grade, the velocity profile providing a plurality of velocity vectors, the velocity profile including a first uphill velocity that is slower than a first downhill velocity for grades below the transition grade and a second uphill velocity that is the same as a second downhill velocity for grades above the transition grade, cause the velocity profile to be stored, access the stored velocity profile during an execution of a drive cycle along the route by the vehicle, and based on receipt of route information obtained during the execution of the drive cycle along the route by the vehicle and based on the stored velocity profile, determine a new velocity vector for a discrete section of the route; wherein the communication module transmits vehicle operating condition data to one of a transmission control unit or a display based on the new velocity vector.
