Vehicular abnormality detecting device
First Claim
1. An abnormality detecting device for executing abnormality detecting of a vehicle after and while an ignition switch of the vehicle is turned off, the abnormality detecting device comprising:
- activating means for causing an electronic control unit of the vehicle to automatically activate the electronic control unit itself so that the abnormality detecting is executed after and while the ignition switch is turned off; and
interval setting means for setting a time interval at which the activating means causes the electronic control unit to automatically activate itself, wherein the time interval is set based on a vehicular state before the ignition switch is turned off.

Abstract
Abnormality of a vehicle is detected while the vehicle is being parked. System normality is set when a tank internal pressure is K2 or more for time T1 or more. System abnormality is set when the tank internal pressure is K3 (K3<K2) or more and less than K2 after time T1 and a tank internal temperature variation is less than C1. System interim abnormality is set when an interim abnormality counter reaches M1. The interim abnormality counter is incremented when the tank internal pressure is less than K3 and other predetermined vehicle states suffice.

12. A program storage media readable by a computer, tangibly embodying an abnormality detecting program of instructions executable by the computer to perform method steps for executing abnormality detecting of a vehicle after and while the ignition switch of the vehicle is turned off, the method steps including:
-
a step of setting a time interval at which an electronic control unit of the vehicle is activated after and while the ignition switch is turned off, wherein the time interval is set based on a vehicular state before the ignition switch is turned off; and a step of causing the electronic control unit of the vehicle to automatically activate the electronic control unit itself at the time interval set at the step of setting the time interval so that the abnormality detecting is executed after and while the ignition switch is turned off.
