BMW EVs Could Be More Fun with Customizable Performance Traits


  • BMW has submitted a patent with the US Patent and Trademark Workplace for adjustable pace and acceleration curves, as first reported by Carbuzz.
  • The system would let drivers customise throttle response and conduct beneath acceleration, even making it in order that automobile may imitate the traits of a gas-powered car.
  • BMW calls it “a enjoyable interactive choice” and describes the customizable graphs as having “an emotional character.”

Nowadays, most automobiles might be tailor-made to totally different situations by means of an array of drive modes, however a brand new patent submitting from BMW suggests the following wave of electrical autos could change into much more customizable. As first reported by Carbuzz, BMW is growing a system that can let drivers create their preferrred driving expertise by adjusting particular components of the drivetrain, similar to acceleration curves and throttle mapping.

The Driver Is the Programmer

Whereas the drive modes presently discovered throughout the automotive panorama can alter these identical parameters, the quantity of adjustability is usually predetermined by the programming of every mode. For instance, Sport mode will intensify the throttle response in a particular means decided by the automaker, whereas Consolation mode will dial it again, however with none adjustability between the 2 preset values.

The proposed BMW system, nonetheless, turns the driving force into the programmer, in a way, permitting for minute changes of every component regardless of any preset drive mode. This stage of personalization is simply possible with electrical motors, the place—as BMW explains within the patent submitting—”… the event of energy … can … be set way more finely and particularly might be various way more flexibly than within the case of inside combustion engines.”

The custom-made propulsion settings revolve round two adjustable graphs: a pace curve and an acceleration curve. The previous permits mapping of the throttle place to immediately correspond to hurry. For instance, the driving force may set it in order that at 30 p.c throttle, the automobile will go 40 mph. The acceleration curve, alternatively, equates throttle enter to torque output. On this case, a driver may set 50 p.c throttle to end in 50 p.c acceleration, in have an effect on figuring out how responsive the throttle pedal is by adjusting how aggressively the automobile responds to inputs.

The patent means that BMW would supply preset graphs, with linear or exponential curves, but additionally the power to customise the curves by dragging totally different factors up and down. The 2 curves would mixed to create an enormous spectrum of distinctive behaviors, with throttle inputs controlling each the general pace and the way aggressively the car accelerates.

An Train to Improve Engagement

BMW seems to view this method as a technique to make high-performance EVs extra participating. The patent explains the customizable graphs “can have an emotional character and delight the car person,” describing the system as “a enjoyable interactive choice” and that “technology-minded car customers will particularly take pleasure in this.”

The system would supply an alternative choice to the best way many EVs presently drive, the place torque and energy supply feels linear and speedy. The system would enable for pace and acceleration to construct regularly, and the adjustable curves may even enable drivers to arrange their automobiles to mimic the acceleration curves of gas-powered automobiles.

It’s unclear if and when BMW intends to implement this method, but it surely may seem on the quad-motor M division prototype beneath growth and/or on the rumored 1000-hp i5 M coming later this decade.
