Optimizing vehicle performance based on route data

A recently granted patent (Publication Number: US11884124B2) outlines a method for adjusting the operation of a vehicle's drivetrain, which includes an engine, e-axle, battery system, and motor/generator. The method involves determining the route of the vehicle, the starting state of charge (SOC) of the battery system, and a target end SOC for a portion of the route. Based on these parameters, a predicted end SOC is calculated, and a performance plan is devised to adjust the drivetrain configuration if needed. This adjustment can involve lowering or raising the e-axle to optimize efficiency based on the comparison between the predicted and target end SOC.

Furthermore, the patent also describes a system for controlling the operation of the vehicle's drivetrain, which includes a sensor for determining the vehicle's location over a route and a controller that executes instructions to determine the drivetrain configuration, starting SOC, target end SOC, and predicted end SOC. The controller then generates a performance plan to adjust the drivetrain configuration, such as lowering or raising the e-axle, based on the comparison between the predicted and target end SOC. Additionally, the system takes into account factors like traffic, road conditions, weather, vehicle weight, and cargo load to optimize the vehicle's efficiency and performance while traveling over the route. This innovative method and system aim to enhance the overall operation and energy management of the vehicle's drivetrain for improved performance and sustainability.
