Audi has filed a patent application for technology that would actively determine the most efficient driving route for a plug-in hybrid vehicle.
The patent is for a navigation system that would determine the best route for maximizing the range of a hybrid car’s battery. The system would work in unison with the drivetrain and adjust the route based on the situation at hand. For example, if the battery were depleted, the route may be different than if it were at a full charge. The system would also offer the driver the ideal route if they want to travel under electric power alone, or give them a route that would better allow the combustion engine to charge the battery.
In theory, the efficiency-minded navigation system would allow drivers of plug-in hybrid vehicles to complete the majority of their trip under electric power alone more often. Audi says the majority of hybrid drivers prefer to travel under EV power only when possible, so this tech would be a welcome addition to plug-in hybrids of the future. Unlike some patents for future tech, this one seems easy enough to implement, so don’t be surprised if we see it on an Audi plug-in sooner rather than later.
