Abstract:
A system and method for adjusting a drivetrain comprising an e-axle on a vehicle comprises accessing route data and compressing the route data into a plurality of linearized segments. Each segment is determined by analyzing points along the route to determine when a set of route data points indicates an uphill, downhill, or flat segment. Using the segments, drivetrain configuration information for a vehicle and a weight of the vehicle, embodiments determine a performance plan that is tailored to the vehicle, including raising the e-axle to reduce rolling resistance on some segments and lowering the e-axle for some segments for increased power for acceleration, improved braking, or increased regenerative capabilities.
