摘要： Driving attentiveness judging method and apparatus for accurately determining the driver's attentiveness level during driving of a motor vehicle are provided wherein steering angle data and vehicle speed data, respectively supplied from a steering angle sensor and a vehicle speed sensor, are sampled by a steering angle data sampling section and a vehicle speed data sampling section, respectively. Respective levels of road shape component, visual steering component, and corrective steering component of the steering angle data are detected by a steering angle data processing section, and a fuzzy inference output representing a driving attentiveness level is obtained by a fuzzy inference section in accordance with fuzzy rules and the three steering component levels. In accordance with the fuzzy inference output which has been subjected to vehicle speed-dependent correction by a vehicle speed correcting section, the driving attentiveness level is displayed at a display device, and also a warning mark is displayed if the vehicle speed-corrected fuzzy inference output is small.
