Patent ID: 8880260

Claim:
A vehicular power supply failure time safety measures control apparatus for a vehicle equipped with an electric park lock mechanism to lock rotation of a wheel, the power supply failure time safety measures control apparatus comprising: a power supply failure detecting section to detect occurrence of a power supply failure including one of charge inability and charge malfunction in a park lock power supply of the park lock mechanism; an electric storage state examining section to examine an electric storage state of the park lock power supply on and after a time of detection of the power supply failure by the power supply failure detecting section; and a park lock section to lock rotation of the wheel by operating the park lock mechanism, under a vehicle speed condition allowing rotation lock of the wheel with the park lock mechanism, when the electric storage state of the park lock power supply judged by the electric storage state examining section approaches a lower limit of the electric storage state ensuring operation of the park lock mechanism; wherein the park lock power supply includes only one electric power source unit and the park lock section is configured to lock rotation of the wheel by operating the park lock mechanism with electric power of said only one electric power source unit of the park lock power supply, when the electric storage state of the park lock power supply judged by the electric storage state examining section approaches the lower limit of the electric storage state ensuring operation of the park lock mechanism.
