PURPOSE:To obtain an accurate risk evaluated value by providing a detection state for a risk contribution state to be evaluated and a risk evaluation part which employs fuzzy reasoning. CONSTITUTION:The state of the contribution of a moving body or its driver to be evaluated to risk is detected by a Doppler radar main body 30, a speed detector 38, a main engine rotating speed detector 43, and a steering operation detection part 44 respectively. A risk evaluation unit 42 receives their signals indicating the risk contribution state as fuzzy input values and performs the fuzzy reasoning to perform continuous risk evaluation. When the evaluated value exceeds a constant value, an alarm 45 warns the driver. Thus, the risk can be evaluated matching human empirical evaluation without measuring the absolute value of an object distance, so wrong risk evaluation based upon a false signal is not performed. |
