Abstract: Disclosed are an apparatus and a method for alarming danger when an automobile is cornering on a downhill road. The apparatus has a speed sensor, a road wheel angle sensor, a steering angle sensor, first and second inclination detecting sections, a judgment section, and an alarming section. In the method, whether speed of the automobile is above a predetermined value or not is determined, and then whether the automobile is cornering on a downhill road or not is determined. When the automobile is cornering on a downhill road, whether the cornering is safely in progress or not is determined, from the road wheel angle, the speed of the automobile, and the longitudinal and transverse inclinations. When the cornering is unsafely in progress, it is notified to a driver of the automobile.
