VEHICLE DIAGNOSIS SYSTEM AND METHOD
First Claim
Patent Images
1. A vehicle diagnosis system disposed in a vehicle, the vehicle diagnosis system comprising:
- an accelerator-off counter counting accelerator-offs each of which representing an occurrence of an accelerator-off state;
a temporal-stop counter counting temporal-stops of an engine during an accelerator-off period; and
one ofan output section outputting an accelerator-offs count and a temporal-stops count to an external device that is different from the vehicle, oran abnormality determiner determining whether a vehicle abnormality regarding a temporal-stop of the engine is caused, which cancels a greenhouse gas reduction effect by the temporal stop of the engine, based on the accelerator-offs count and the temporal-stops count.

Abstract
A vehicle diagnosis system includes an abnormality determiner for determining whether a vehicle having an abnormality regarding a temporal engine stop function or a power regeneration function is caused in a mode that cancels a greenhouse gas reduction effect of the engine. When an abnormality that cancels, due to disablement of the temporal engine stop function or the power regeneration function, such an abnormality is quickly notified to a driver of the vehicle by the vehicle diagnosis system so that the abnormality is quickly fixed.

2. A vehicle diagnosis system disposed in a vehicle, the vehicle diagnosis system comprising:
-
an accelerator-off counter counting accelerator-offs that represent a number of occurrences of an accelerator-off state; an inactive temporal-stop counter counting inactive temporal-stops of the engine during an accelerator-off period; and one of an output section outputting an accelerator-offs count and an inactive temporal-stops count to an external device that is different from the vehicle, or an abnormality determiner determining whether a vehicle abnormality regarding a temporal-stop of the engine is caused, which cancels a greenhouse gas reduction effect by the temporal-stop of the engine, based on the accelerator-offs count or the inactive temporal-stops count. - View Dependent Claims (8, 9)
