Embodiment Construction

[0039] figure 1 is a schematic structural diagram of a vehicle secondary oil pump control system according to an embodiment of the present invention. Such as figure 1 As shown, the vehicle secondary oil pump control system disclosed in the present invention includes a controller 1 (such as the vehicle's engine controller ECM) and a secondary oil pump 2 . Wherein, the controller 1 generates a control signal based on at least one control parameter, and transmits the control signal to the secondary oil pump 2 . The secondary oil pump 2 changes its working state based on the received control signal.

[0040] Preferably, in the vehicle secondary oil pump control system disclosed in the present invention, the working state includes a high-pressure mode and a low-pressure mode.

[0041] Preferably, in the vehicle secondary oil pump control system disclosed in the present invention, the secondary oil pump 2 includes a solenoid valve 3, and the secondary oil pump 2 controls the elec...

Abstract

The invention provides a vehicle second-level oil pump control system and method. The method includes the steps of generating a control signal on the basis of at least one control parameter, and changing the working state of a second-level oil pump on the basis of the control signal. The vehicle second-level oil pump control system and method can accurately control the working state of the second-level oil pump.

Description

technical field [0001] The present invention relates to a control system and method, more specifically, to a vehicle secondary oil pump control system and method. Background technique [0002] Currently, with the increasing development and popularity of vehicles, it is becoming more and more important to lubricate the engine of the vehicle by using a secondary oil pump that works by being driven by the engine belt. [0003] In the existing technical solution, the secondary oil pump usually has two working states of high-pressure mode and low-pressure mode, and under specific working conditions. Selecting to use the low-pressure mode can reduce the consumption of engine torque by the oil pump, thereby improving the fuel economy of the whole vehicle. [0004] However, the existing technical solutions have the following problems: due to the inaccurate control of the working mode of the secondary oil pump, if the low-pressure mode is continuously used, it will affect the lubric...
