Abstract
A vehicle diagnosis system determines whether a vehicle has an abnormality in a temporal engine stop function or a power regeneration function that negates a greenhouse gas reduction effect of the engine. When the vehicle diagnosis system determines an abnormality, the vehicle diagnosis system provides a notification of the abnormality.
Claims6
A vehicle diagnosis system for performing a diagnosis for a vehicle having a temporal engine stop function that temporarily stops an engine of the vehicle in a certain condition satisfied state, the vehicle diagnosis system comprising:
- a sensor detecting a parameter associated with the vehicle;
- a controller, including a computer processor and memory, the controller being configured at least to:
- determine an occurrence of a specific abnormality of the vehicle based on the detected parameter, the specific abnormality being an abnormality that cancels a greenhouse gas reduction effect by the temporal engine stop function, wherein
- the specific abnormality is an abnormality that hinders or delays (i) a satisfaction of a condition of a temporal stop of the engine or (ii) a determination of satisfaction of the condition of the temporal stop of the engine;
- and
- even though an accumulated value of an input power to a battery installed in the vehicle in a current trip is greater than a specified value, the specific abnormality includes an abnormality that hinders or delays (i) a reaching of a remaining charge amount of the battery installed in the vehicle to a standard amount as the satisfaction of the condition or (ii) a detection of the reaching of the remaining charge amount to the standard amount as the determination of the satisfaction of the condition;
- and
- provide an output, via a communicator of the vehicle, to a device, that is external from the vehicle, based on the determined occurrence of the specific abnormality.
A vehicle diagnosis method for performing a diagnosis for a vehicle having a temporal engine stop function that temporarily stops an engine of the vehicle in a certain condition satisfied state, the vehicle diagnosis method comprising:
- detecting, using a sensor, a parameter associated with the vehicle;
- determining, using a controller including a computer processor and memory,
- an occurrence of abnormality of the vehicle based on the detected parameter, which includes determining whether a specific abnormality is occurring, and
- whether the specific abnormality is an abnormality that cancels a greenhouse gas reduction effect by the temporal engine stop function;
- wherein
- the specific abnormality is an abnormality that hinders or delays (i) a satisfaction of a condition of a temporal stop of the engine or (ii) a determination of satisfaction of the condition of the temporal stop of the engine;
- and
- even though an accumulated value of an input power to a battery installed in the vehicle in a current trip is greater than a specified value, the specific abnormality includes an abnormality that hinders or delays (i) a reaching of a remaining charge amount of the battery installed in the vehicle to a standard amount as the satisfaction of the condition or (ii) a detection of the reaching of the remaining charge amount to the standard amount as the determination of the satisfaction of the condition;
- and
- providing an output, via a communicator of the vehicle, to a device, that is external from the vehicle, based on the determined occurrence of the specific abnormality.
