Abstract
The invention is related to laser diode based self-mixing laser sensors for simplified vehicle stability control. Vehicle's side slip angle, front and rear tire slip angles, yaw rate and lateral acceleration rate are derived explicitly from self-mixing laser sensors. Three criteria based on yaw rate, turn radius and tire slip angle analysis are employed to detect the occurrence of understeer or oversteer, which enables simplified vehicle electronic stability program.
