Self-adaptive auxiliary oil pump motor rotation speed control method

The invention discloses a self-adaptive auxiliary oil pump motor rotation speed control method. The self-adaptive auxiliary oil pump motor rotation speed control method comprises the following steps that after the IGON enabling end of a controller receives an effective signal, real-time oil temperature messages, real-time oil way pressure messages and target rotation speed message information on a CAN are received; whether the driving capability of an auxiliary oil pump motor meets the demand for target rotation speed or not is judged under the real-time working conditions (real-time oil temperature and real-time oil way pressure), and an overload judgment result is generated; the target rotation speed is adjusted according to the overload judgment result, and real-time rotation speed and residual working time are uploaded to the whole machine CAN. By the adoption of the self-adaptive auxiliary oil pump motor rotation speed control method, the overload caused by the fact that the demand for target rotation sp
