Abstract
A dynamic behavior estimate system of an automotive vehicle includes a parameter reading unit which reads an input signal indicative of one of vehicle behavior parameters when the vehicle operates in a curved path. A discriminating unit outputs a detection signal indicative of discrimination of an instability of the vehicle when an inference value from the above one of the vehicle behavior parameters exceeds a reference value. A slip angle detecting unit detects a maximum slip angle that can hold a lateral force of front or rear wheels of the vehicle below a critical value, and sets the reference value equal to the maximum slip angle. An inference value setting unit determines an inference value from the above one of the vehicle behavior parameters, and sets the value, used by the discriminating unit, equal to the inference value, thereby allowing the discriminating unit to detect whether the inference value exceeds the reference value.
