Idling stop control system for vehicle
View Patent ↗An idling stop control system stops an idling of an engine so as to automatically stop the engine in the case where a predetermined condition on automatic stop of the engine is established and releases the automatic stop of the engine so as to restart the engine in the case where a predetermined condition on restart of the engine is established in accordance with a driving condition of the vehicle. The idling stop control system recognizes a type of an object in front of the vehicle and restarts the engine depending on the type of the object in front of the vehicle even if the engine is in the automatic stop and the restart condition of the engine is not established with respect to the driving condition.
1. An idling stop control system for a vehicle, which stops an idling of an engine of the vehicle so as to automatically stop the engine in the case where a predetermined condition on automatic stop of the engine is established, and releases the automatic stop of the engine so as to restart the engine in the case where a predetermined condition on restart of the engine is established in accordance with a driving condition of the vehicle, the idling stop control system comprising:
a front information recognition unit that recognizes an object in front of the vehicle and assigning one of a plurality of predetermined types to the object; and
a restart determination unit that determines the restart of the engine depending on the assigned type of the object in front of the vehicle, even if the restart condition of the engine is not established during the automatic stop of the engine, wherein:
in response to a determination that the assigned type of the object is a first predetermined type of the plurality of predetermined types and the front information recognition unit detects a position change of the object, the idling stop control system performs the restart of the engine,
in response to a determination that the assigned type of the object is one of the plurality of predetermined types not including the first predetermined type, the idling stop control system prohibits the restart of the engine, and
in response to a determination that the assigned type of the object immediately in front of the vehicle is a motorcycle and the front information recognition unit recognizes that another vehicle in front of the motorcycle and in the same lane as the vehicle is at a stop, the restart determination unit determines to prohibit the restart of the engine even if the motorcycle moves.
2. The idling stop control system for a vehicle according to claim 1 , wherein, in response to a determination that the assigned type of the object immediately in front of the vehicle is a pedestrian, the restart determination unit determines to prohibit the restart of the engine.
3. The idling stop control system for a vehicle according to claim 1 , wherein in response to a determination that the assigned type of the object in front of the vehicle is a four-wheel vehicle, the restart determination unit determines to release automatic stop of the engine to restart the engine when the four-wheel vehicle moves.
4. The idling stop control system for a vehicle according to claim 2 , wherein, in response to a determination that the assigned type of the object in front of the vehicle is a four-wheel vehicle rather than a pedestrian, the restart determination unit determines to release automatic stop of the engine to restart the engine when the four-wheel vehicle moves.
5. An idling stop control system for a vehicle, which stops an idling of an engine of the vehicle so as to automatically stop the engine in the case where a predetermined condition on automatic stop of the engine is established, and releases the automatic stop of the engine so as to restart the engine in the case where a predetermined condition on restart of the engine is established in accordance with a driving condition of the vehicle, the idling stop control system comprising:
a front information recognition unit that recognizes an object in front of the vehicle and assigning one of a plurality of predetermined types to the object; and
a restart determination unit that determines the restart of the engine depending on the assigned type of the object in front of the vehicle and, even if the restart condition of the engine is not established during the automatic stop of the engine, wherein:
in response to a determination that the assigned type of the object immediately in front of the vehicle is other than a four-wheel vehicle and when the front information recognition unit recognizes a pre-preceding vehicle existing in front of the object on the same lane as the vehicle is at a stop, the restart determination unit determines to prohibit the restart of the engine.
