Sense Of Control
All the electronic gadgets and driver aids you find in cars these days are largely attributed to the emergence of high-performance computers. The real stars, however, are those tiny devices we call sensors, because these things have evolved to become smaller, more accurate and immensely more robust. This means that they can be installed in tight spaces where conditions may be harsh (hot, high vibration, extreme pressure) and still supply the computer with accurate and timely data. Despite having grown smaller, the sensor’s role in the electronic management of the modern vehicle’s performance has never been bigger. Every car manufactured today needs sensors in the engine, while at the high end, cars like the BMW 7 Series and Lexus LS rely on a bewildering array of sensors for the control of engine performance, gearbox activity, braking, body/chassis dynamics, traction, air-con …
and the list goes on. +Continue Reading
