Embodiment approach
[0071] Optionally, in another embodiment of the present application, an implementation manner of step S203 includes:
[0072] According to the first angle information of the crankshaft and the rotation angle of the crankshaft every time one resolver cycle passes, it is determined that the resolver cycle in which the first resolver position variable is currently located is the Nth resolver cycle.
[0073] Continuing the above example, the angle of rotation of the crankshaft after each revolution cycle can be obtained by calculation: in one working cycle of the engine, the crankshaft needs to rotate twice, and 12 revolution cycles can be obtained, that is, 360*2 / 12=60°, then when obtaining the first angle information, such as 132°, directly divide the first angle information by the angle 60° of crankshaft rotation every time a resolver cycle passes, and obtain the first angle information after 2 The resolver period, and the result of 12° more, that is, the resolver period in wh...
