Abstract: Aiming at engine startup failure and low oil pressure faults induced by sticking of the electronic oil pump (EOP) solenoid valve in hybrid vehicle range-extender systems, this paper proposes a multi-scene collaborative self-cleaning control strategy for the solenoid valve. By analyzing various vehicle operating conditions and taking vehicle speed, power supply voltage and temperature as constraint boundaries, the strategy drives the oil pump solenoid valve through adjustable high-frequency duty-cycle signals. Four coordinated control schemes covering daily prevention, startup guarantee, shutdown maintenance and fault emergency response are formulated. The proposed method overcomes the limitations of traditional maintenance relying on component disassembly, and has important engineering value for improving the operational reliability and safety of range-extended hybrid systems.
