Rezumat: Pentru soferii de automobile cat si pentru manufacturieri, siguranta automobilului este de mare importanta. Derapajul la roata este un factor in siguranta si performanta vehiculului. Se cerceteaza determinarea diferentelor de viteza intre roti si vehicul, folosind un accelerometru si encodere. Se exemplifica metode de compensare si calibrare a acceleratiei gravitationale, necesare pentru determinarea vitezei vehiculului. Derapajul la roata se simuleaza si observa experimental.

Cuvinte cheie: derapaj la roata, viteza, accelerometru, gravitatie


Abstract: Vehicle safety is a great concern for automotive drivers and manufacturers. Wheel slip is a factor in safety, also in performance. Determination of wheel speed differences to the vehicle speed through an accelerometer and encoders is reaserched. Methods of compensation and calibration of gravitational acceleration are exemplified, necessary for vehicle speed determination. Wheel slip is simulated and experimentally observed.

Keywords: wheel slip, speed, accelerometer, gravity
