Vehicular warning system and method

A vehicular warning system comprising:

• an image information generating module for generating image information associated with at least one of a driver of a vehicle and a position of the vehicle;
• an operation information generating module for generating operation information associated with operation of the vehicle;
• a processing module electrically connected to said image information generating module and said operation information generating module for respectively receiving the image information and the operation information therefrom, said processing module determining a first risk value with reference to the image information, further determining a second risk value with reference to the operation information, further determining a risk index indicative of a degree of risk with reference to the first and second risk values, and generating an alert-triggering signal when the risk index reaches a predetermined index threshold;
• and
• an alert module electrically connected to said processing module for receiving the alert-triggering signal therefrom, and generating an alert signal of one of sound, light and pictures in response to the alert-triggering signal,
• wherein the vehicle includes a vehicle body and a handling module, wherein said operation information generating module includes a lateral acceleration sensor unit to be mounted on the vehicle body for detecting a lateral acceleration of the vehicle body, a steering angle sensor unit to be mounted on the vehicle body for detecting a steering angle of the vehicle body, and a steering torque sensor unit to be mounted on the handling module for detecting a steering torque of the handling module, the operation information being composed of the lateral acceleration of the vehicle body, the steering angle of the vehicle body and the steering torque of the handling module,
• wherein said processing module determines the second risk value by performing fuzzification and defuzzification on the lateral acceleration of the vehicle body, the steering angle of the vehicle body and the steering torque of the handling module with reference to a predetermined set of membership functions and a predetermined set of fuzzy rules,
• wherein the fuzzification is performed using triangular and trapezoidal fuzzifiers, and the defuzzification is performed according to the weighted average defuzzification technique.
