The invention provides a vehicle air conditioning torque reserve via a belt drive starter generator. A vehicle includes an air conditioner (AC) compressor, an engine, a belt drive starter generator (BISG), and a controller. The controller compares a first AC torque demand required to engage the AC compressor to an available torque from the BISG in response to detecting a first AC compressor engagement condition. The controller also engages the AC compressor using the available torque from the BISG and engine torque from the engine in response to the available torque being insufficient to engage the AC compressor to compensate for torque shortage between AC torque demand and available torque by retarding spark timing and increasing intake air.

    本公开提供了“经由带传动起动发电机的车辆空调扭矩储备”。一种车辆包括空调(AC)压缩机、发动机、带传动起动发电机(BISG)和控制器。所述控制器响应于检测到第一AC压缩机接合状况而将接合所述AC压缩机所需的第一AC扭矩需求与来自所述BISG的可用扭矩进行比较。所述控制器还响应于所述可用扭矩不足以接合所述AC压缩机而使用来自所述BISG的所述可用扭矩和来自所述发动机的发动机扭矩来接合所述AC压缩机,以通过延迟火花正时并增加进气来补偿AC扭矩需求和可用扭矩之间的扭矩短缺。
