Claim 0:
1. A vehicle comprising:
an air-conditioning (AC) compressor including a shaft;
an engine configured to be selectively mechanically coupled to the shaft;
a belt-integrated starter generator (BISG) configured to be selectively mechanically coupled to the shaft; and
a controller configured to,
responsive to a request for torque from the AC compressor, an available BISG torque from the BISG being insufficient to satisfy the request, and an absence of demand for negative torque from the engine to decelerate the vehicle, mechanically couple the BISG and engine to the shaft and retard spark timing of the engine,
responsive to the request, the available BISG torque being sufficient to satisfy the request, and the absence of the demand, mechanically couple the BISG to the shaft without retarding the spark timing of the engine while the engine is running, and
responsive to the request, the available BISG torque being sufficient to satisfy the request, and presence of the demand, wherein the demand exceeds a threshold value, mechanically couple the engine to the shaft without mechanically coupling the BISG to the shaft.
