Embodiment Construction
[0053] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.
[0054] The present invention is made by the inventor based on the following problems and awareness:
[0055] In related technologies, creep control is usually implemented through the following control strategies, specifically as follows:
[0056] The first control strategy is: directly close the clutch during the creeping process, and realize creeping by controlling the motor speed; the second control strategy is: TCU requests a constant idle speed for the motor under any working conditions, and realizes creeping by controlling the clutch. Among them, creeping refers to a state in which the whole vehicle goes from static to stable speed after the shift lever is in D or R, the brake is released, and the accelerator is not stepped on.
[0057] However, since the engine starts to rely on the P2 motor to drive ...
