BMW patents means to tailor EV drive modes


Drive modes are nothing new, however BMW could go for extra detailed customization in future efficiency EVs.

First noticed by CarBuzz, a latest patent software filed with america Patent and Trademark Workplace (USPTO) goes past present drive modes, permitting drivers to tailor issues like throttle mapping and torque supply to dramatically change the habits of a automobile.

As a substitute of a restricted variety of modes like Sport and Eco with mounted settings, this method would give drivers a graph from which they may select customized settings, based on the applying. It takes benefit of the higher flexibility of electrical motors, which will be powered up or down in a linear vogue, like a dimmer swap. And since most electrical powertrains use single-speed gearboxes, automobile velocity extra instantly correlates to accelerator-pedal place.

Benefiting from these qualities, BMW’s proposed system relies round acceleration and velocity curves. The acceleration curve is much like the throttle mapping utilized in present internal-combustion vehicles, and the velocity curve equalizes a sure pedal place to a sure velocity. Each will be adjusted by dragging the curve line alongside a graph displayed on a automobile’s touchscreen, per the applying, which additionally means that BMW’s Hans Zimmer-designed EV sounds may shift relying on these changes.

As CarBuzz notes, there are a couple of potential advantages to this method. By selecting non-linear velocity or acceleration curves, drivers may mimic the habits of an internal-combustion automobile, quickly disabling the flat torque curve inherent to an electrical motor in favor of the peaks and valleys of a gasoline engine’s torque curve. Vehicles may be programmed to speed up extra step by step than they might in any other case, offering a security web for novice drivers or these not used to the facility or sudden acceleration of efficiency EVs.

Patented concepts do not at all times make it to manufacturing, however we all know that BMW is planning electrical M vehicles. It already sells the iX M60 and i4 M50, and just lately confirmed the 650-hp i7 M70. It has additionally teased fashions with extra intensive upgrades, together with a four-motor drivetrain.
