Vehicle diagnosis system and method
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.
1. 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
the specific abnormality includes an abnormality that hinders or delays (i) a reaching of a remaining charge amount of a 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 which is determined when the remaining charge amount has not reached the standard amount after a preset time even though charging to the battery is performed; 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.
2. The vehicle diagnosis system of claim 1 , wherein
the specific abnormality includes an abnormality that hinders or delays (i) a reaching of an engine cooling water temperature to a standard temperature as the satisfaction of the condition or (ii) a detection of the reaching of the engine cooling water temperature to the standard temperature as the determination of the satisfaction of the condition.
3. The vehicle diagnosis system of claim 1 , wherein
the specific abnormality includes an abnormality that hinders or delays (i) a reaching of a sensor temperature of a sensor that is disposed in an exhaust passage of the engine to a standard temperature as the satisfaction of the condition or (ii) a detection of the reaching of the sensor temperature to the standard temperature as the determination of the satisfaction of the condition.
4. The vehicle diagnosis system of claim 1 , wherein
the specific abnormality includes an abnormality that hinders or delays (i) a reaching of an inter-terminal voltage of a battery disposed in the vehicle to a standard voltage as the satisfaction of the condition or (ii) a detection of the reaching of the inter-terminal voltage to the standard voltage as the determination of the satisfaction of the condition.
5. The vehicle diagnosis system of claim 1 , wherein
the specific abnormality includes an abnormality that hinders or delays (i) a reaching of an oil temperature of a transmission disposed in the vehicle to a standard temperature as the satisfaction of the condition or (ii) a detection of the reaching of the oil temperature to the standard temperature as the determination of the satisfaction of the condition.
6. 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
the specific abnormality includes an abnormality that hinders or delays (i) a reaching of a remaining charge amount of a 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 which is determined when the remaining charge amount has not reached the standard amount after a preset time even though charging to the battery is performed; 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.
