1. A system for monitoring slip angle of a vehicle comprising:

  • longitudinal acceleration monitoring means for monitoring longitudinal acceleration exerted on said vehicle and producing a longitudinal acceleration inicative signal;

    lateral acceleration monitoring means for monitoring lateral acceleration exerted on said vehicle and producing a lateral acceleration indicative signal;

    a wheel speed sensor for monitoring rotation speed of a vehicular wheel to produce a wheel speed indicative signal; and

    an arithmetic circuit for receiving said longitudinal acceleration indicative signal, said lateral acceleration indicative signal and said wheel speed indicative signal, said arithmetic circuit deriving a basic slip angle on the basis of values of said longitudinal acceleration indicative signal and said lateral acceleration indicative signal, and corecting said basic slip angle with a correction factor derived on the basis of said wheel speed indicative signal.
