SPATIAL DOMAIN OPTIMAL ELECTRIC AND HYBRID ELECTRIC VEHICLE CONTROL WITH PATH FORECASTING

摘要

A vehicle engine, electric machine and battery are operated, in certain examples, such that a predetermined route is segmented based on varying criteria to determine target battery state of charge at the segment endpoints along the route. The endpoints are a superposition of endpoints defined by predicted powertrain operating mode transitions, predicted vehicle acceleration transitions or predicted road grade transitions along the route.

主权项

1. A vehicle comprising:
a battery; an engine; an electric machine; and at least one controller programmed to, for each of a plurality of route segments having an endpoint defined by a geographic location and a target battery state of charge (SOC), operate the engine and electric machine to achieve the target battery SOC, wherein the endpoints are a superposition of endpoints defined by predicted powertrain operating mode transitions, predicted vehicle acceleration transitions or predicted road grade transitions along the route.
