BMW Files Patent for Adjustable Speed and Acceleration Curves
BMW has filed for a patent with the United States Patent and Trademark Office for adjustable speed and acceleration curves, as reported by Carbuzz. The proposed system would allow drivers to customize throttle response and behavior under acceleration. In effect, the car could imitate the characteristics of a gas-powered vehicle. BMW calls it “a fun interactive option” and describes the customizable graphs as having “an emotional character.”
While many cars on the market have drive modes that can alter the same parameters, such as Sport and Comfort modes, preset value adjustments limit the level of customizability. The BMW system aims to turn drivers into programmers by allowing minutely-detailed adjustments of each element. This level of personalization is only feasible with electric motors, as BMW explains that developing power in electric motors can be set and varied much more finely than in the case of combustion engines.
The customizable propulsion settings revolve around two adjustable graphs: a speed curve and an acceleration curve. Mapping of the throttle position to speed and torque output, respectively, is made possible by these graphs. A driver could set it to respond aggressively to inputs or build speed and acceleration gradually.
BMW views this system as an exercise to increase engagement and make high-performance EVs more enjoyable. In response to the linear and immediate torque and power delivery currently found in many EVs, the system would instead allow for a more customizable driving experience. Drivers could set up their cars to imitate the acceleration curves of gas-powered cars.
It is unclear when or if BMW intends to implement this system. It could appear on the quad-motor M division prototype under development, or on the rumored 1000-hp i5 M coming later this decade.
