DRIVING ASSISTANCE METHOD AND DEVICE
First Claim
1. A driving assistance method for assisting a vehicle driver by securing a driving behavior from an acceleration of an automotive vehicle, which has been detected by an acceleration sensor mounted on the automotive vehicle, and evaluating such driving based on the driving behavior;
- in which for each type of the driving behaviors, the frequency of occurrence of the incidents of the particular behavior in predetermined driving units is measured and the measured frequency of occurrence of the incidents is displayed for each particular behavior as the driving evaluation index aimed at a zero number; and
in which for each type of driving behaviors, a mean time between incidents of the particular behavior or a mean distance between incidents of the particular behavior is calculated on the basis of the frequency of occurrence of the particular behavior, which is a proportion of the number of occurrence of the each type of the particular behavior relative to a predetermined driving hour or a predetermined driving distance, which is a predetermined driving unit, and such mean time between the incidents or such mean distance between the incidents is displayed as a driving evaluation index.

Abstract
The present invention measures the frequency of occurrence of behaviors of a particular behavior for each time within a predetermined driving unit for each type of driving behaviors and causes the measured frequency of occurrence on a display unit as a driving evaluation index aimed at attaining a zero number each time the particular behavior takes place. Also, for each type of the driving behaviors, based on the frequency of occurrence of the particular behavior, which is a proportion of the number of occurrence of the particular behavior for each type relative to a predetermined driving time, which is the predetermined driving unit, the mean time between incidents of the particular behavior is calculated and the calculated mean time between the incidents is used as the driving evaluation index.

8. A drive assistance device comprising an acceleration sensor for detecting the acceleration of an automotive vehicle for securing a driving behavior, a display unit, an electric power unit and a control unit, all mounted on the automotive vehicle for assisting a vehicle driver by evaluating a driving based on the driving behavior;
-
in which a driving behavior occurrence number counting unit counts, for each of the driving behaviors, the number of occurrence of driving behaviors of a particular behavior for each type, and further the counted number of occurrence of the driving behaviors is displayed by the display unit for each occurrence of the particular behavior as a driving evaluation index aimed at the zero number of occurrence; and in which the control unit includes a mean time between incidents or a mean distance between incidents calculating unit for calculating, for each type of driving behaviors, the mean time between incidents of the particular behavior or the mean distance between incidents of the particular behavior based on the frequency of occurrence, which is a proportion of the behavior occurrence number of the particular behavior for that type relative to a predetermined driving time or a predetermined driving distance which is a predetermined driving unit, and further the mean time between the incidents of the particular behavior or the mean distance between incidents of the particular behavior is displayed by the display unit as the driving evaluation index. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
