Abstract
A driving safety control apparatus for a vehicle is provided. In some embodiments, the driving safety control apparatus makes use of a hybrid wheel sensor capable of automatically detecting an abnormal state of one or more chassis components generated when the vehicle is running by using speed and acceleration signals of the hybrid wheel sensor with a semiconductor acceleration sensor mounted on the wheel of the vehicle, thereby informing the driver of the detected abnormal state. In this manner, the detected abnormal part can be repaired at an early stage. Also, the behavior of the vehicle wheels can be monitored, whereby signals representative of the measured behavior can be transmitted to an active suspension for improved control of the active suspension, compared to known systems.
