ROUTE NAVIGATION WITH OPTIMAL SPEED PROFILE

摘要

Energy consumption of a vehicle is optimized while traveling a route assembled of road segments between a first position and a destination. A speed profile generator is located at least partially off of the vehicle and uses an energy consumption model of the vehicle together with road grade data corresponding to the route to calculate an optimal speed profile. The speed profile specifies target speeds for respective locations on the route for traversing the route with an optimized energy consumption. The speed profile generator compares energy consumption for a plurality of feasible speed profile trajectories between a maximum trajectory and a minimum trajectory in order to identify the optimal speed profile. A speed updater is responsive to a current position of the vehicle and the optimal speed profile to initiate the target speed for the current position.

1. A system for optimizing energy consumption of a vehicle, comprising:
a route calculator for assembling road segments into a route from a first position to a destination; a speed profile generator located at least partially off of the vehicle and using an energy consumption model of the vehicle together with road grade data corresponding to the route to calculate an optimal speed profile that specifies target speeds for respective locations on the route for traversing the route with an optimized energy consumption, wherein the speed profile generator compares energy consumption for a plurality of feasible speed profile trajectories between a maximum trajectory and a minimum trajectory in order to identify the optimal speed profile; and a speed updater responsive to a current position of the vehicle and the optimal speed profile to initiate the target speed for the current position.
