Fast Car, Reliable Sensors

Although the auto industry in Finland isn’t exactly large, Valmet Automotive has long been a specialty manufacturer hired by companies including the former-Fisker to build the Karma and the still-existing Mercedes to build the A-Class.

There is another Finnish company worthy of note: Toroidion Oy.

It is notable because it has developed a concept electric supercar, the Toroidion 1MW.

That alphanumeric is as in “one megawatt.”

Or 1,341 hp.

While the details regarding the specifications of the car are scant, it is real to the extent that the company has specified the sensors for the steering wheel and the accelerator pedal—both of which are rather important when you’re talking about driving at 280 mph.

Interestingly, Toroidion has selected industrial-strength sensors from Honeywell Sensing & Productivity Solutions. There is the SPS-LO35-LATS linear sensor and the SPS-R360D rotary sensor.

According to Honeywell, these sensors, which are ordinarily found in heavy-machinery applications, use a patented arrangement of magneto resistive sensors to accurately and reliably determine the position of a magnet on a rotating or linearly moving object. An application-specific integrated circuit (ASIC) calculates and verifies the absolute angle of rotation or the position to 0.01° or 0.04 mm.

Explaining the rationale behind the selection of these sensors, Pasi Pennanen, Toroidion Oy chief executive officer, said, “This type of speed requires an extremely sensitive steering for a comfortable experience and maximum safety at extremely high speed.

“The accelerator pedal must respond very reliably, so that the driver can sensitively accelerate the vehicle at maximum power. Honeywell technology is proven to provide this type of accuracy in challenging and dangerous conditions – that is the type of performance a supercar needs as well.”

While few of us have ever driven at 280 mph, look at it this way: that’s 410.7 feet per second. And given that a football field is 360 feet, you’d hit the end zone in less than a second.

No word on the sensors used for braking.
