Vehicle electrical control system

Abstract

The invention relates to the technical field of car electrical control, in particular to a vehicle electrical control system. The system comprises a low-pressure oil pump, a high-pressure oil pump, acommon rail tube, an oil injector and an electrical control unit; through adjusting the opening degree of an adjusting valve in a low-pressure pipeline on the inlet end of the high-pressure pump, theoil pumping amount of the high-pressure pump is controlled, and the common rail pressure is indirectly controlled; in a low-pressure loop, fuel oil in an oil tank is fed to an oil inlet of the high-pressure pump through the low-pressure pump; in a high-pressure loop, through the high-pressure pump, fuel oil pressure is improved, the high-pressure fuel oil is pumped to an oil rail, and a pressure control valve is arranged on an oil inlet of the high-pressure pump; a one-way valve is arranged on an oil outlet of the high-pressure pump; a pressure limiting valve is arranged on the oil outlet of the high-pressure pump; an execution mechanism is arranged on the common rail pipe, and high-pressure fuel oil is sprayed to a combustion chamber to participate in combustion through the oil injector;and according to the vehicle electrical control system, the product time to market is shortened, the product quality is ensured, cost is reduced, and the dependency on the physical prototype is reduced.
