Beschreibung
Zusammenfassung:	The invention provides an engine response time calculation method and device. The engine response time calculation method and device are applied to the field of engine cylinder deactivation control. The method can comprise the steps that the angle difference between a current valve timing angle and a target valve timing angle of an engine in a torque switching process and the engine oil pressure of a main oil duct of the engine are obtained; the first response time of the engine is calculated according to the angle difference and the engine oil pressure of the main oil duct; the second response time of the engine is calculated according to the engine oil pressure of the main oil duct; and the system response time of the engine is determined according to the first response time and the second response time. By means of the scheme provided by the embodiment of the invention, the system response time actually required by the random cylinder deactivation engine in the torque switching process can be accurately ca
