摘要

A detection unit (101) detects acceleration of a moving body. A judging unit (102) judges whether the acceleration detected by the detection unit (101) reaches a certain level. A guide unit (103) guides caution information if the judging unit (102) judges that the acceleration has reached the certain level. A setting unit (104) sets whether to guide caution information. When the setting unit (104) is set to perform a guide, the guide unit (103) guides caution information. By setting a fellow passenger upon initialization, the setting unit (104) sets a route considering a car thickness.
