О нём не знает почти никто! Но он ЕСТЬ!!! Датчик рыскания... в автомобиле...

Have any of you heard of a sensor called a yaw rate sensor? I doubt many have. In fact, I'd even say some people believe such a sensor doesn't exist... However... It does. It's also called a rotational velocity sensor, or gyrometer. These sensors are used in cars to measure the vehicle's rotational speed around its vertical axis. They are also used in stability control systems, or, more simply, anti-skid systems. At their core, these are micromechanical sensors based on silicon. MM2 sensors have also been developed to detect vehicle rollovers; these sensors measure the vehicle's rotational speed around its longitudinal axis. I hope you've guessed what these sensors are used for. Of course, they are used in passive safety systems. For example, to deploy side airbags in the event of a rollover.
