The invention discloses a vehicle lubricating oil control system. By means of the vehicle lubricating oil control system, the problems that the service life of parts will be shortened and the parts are made to be prone to being strained when lubricating oil can not be supplied to joints of the parts normally are solved. According to the technical scheme, the vehicle lubricating oil control systemis characterized by comprising a main control terminal, a temperature detection module and an oil pump module, the oil pump module is connected with the main control terminal and injects the lubricating oil into the joints of the parts, low temperature ambient temperature and minimum lubricating oil temperature are preset in the main control terminal, and when the temperature corresponding to first temperature detection signals is not less than the low temperature ambient temperature or the minimum lubricating oil temperature, the oil pump module is in working mode and allows starting oil pumping. According to the vehicle lubricating oil control system, by means of the manner that the lubricating oil temperature is detected in real time and in coordination with the oil pump module performing oil pumping, so that oil is supplied to the joints of the parts in time, the service life of the parts is prolonged, and the parts are made to be not prone to being strained.
