Electric vehicle and method of battery set-point control

摘要

A method includes utilizing navigation data from a navigation system to segment a route to be travelled by a travelling vehicle into segments each having a road grade different than neighboring segments. The method further includes discharging a battery of the vehicle as the vehicle travels along an initial segment of the route according to a state-of-charge (SoC) set-point based on the road grade of the initial segment and a variable representative of the road grades of at least two other segments of the route.

1. A method comprising:
utilizing navigation data from a navigation system to segment a route to be travelled by a travelling vehicle into segments each having a road grade different than neighboring segments; discharging a battery of the vehicle, as the vehicle travels along an initial segment of the route, according to a state-of-charge (SoC) set-point from a sequence of SoC set-points for respective segments of a simpler version of the route having the initial segment, a single segment representing the last two or more segments of the route, and any remaining segments of the route, the set-point for the initial segment depending on the set-point for the single segment representing the last two or more segments of the route as the sequence is prescribed to minimize fuel consumption for the simpler version taking into account the road grade of the initial segment and a variable representative of the road grades of the last two or more segments of the route.
