A vehicle includes an internal combustion engine, a HVAC system, and an engine control unit that is configured to automatically stop and restart the internal combustion engine. When the HVAC system isturned off and the engine is stopped, the occurrence of at least one main condition related to a vehicle cooling event requiring operation of the HVAC system is determined, and the engine is automatically started before starting the HVAC system. The ability of the engine control unit to automatically stop the operation of the engine is disabled until the secondary condition associated with the HVAC system is met. When the secondary condition is satisfied, the ability of the engine control unit to at least automatically stop the operation of the engine is reactivated.
一种车辆包括内燃发动机、HVAC系统和发动机控制单元,所述发动机控制单元被配置为自动停止和重新启动所述内燃发动机。在所述HVAC系统被关闭并且所述发动机停止时,确定与需要所述HVAC系统的运转的车辆冷却事件相关的至少一个主要条件的出现,并且在启动所述HVAC系统之前自动启动所述发动机。所述发动机控制单元自动停止所述发动机的运转的能力被禁用,直到满足与所述HVAC系统相关联的次要条件。在满足所述次要条件时,重新启用所述发动机控制单元至少自动停止所述发动机的运转的能力。
