Problems solved by technology
[0002] The oil temperature and oil pressure of the vehicle are an important physical parameter of the vehicle, especially on engineering vehicles. Once these physical parameters change greatly, it will affect the working state of the vehicle and even cause damage to the vehicle.
[0003] Most of the existing technology is through the naked eye observation and on-site observation of technicians, but due to the limitation of the working environment, there are errors in the observation of technicians, and these parameters of the vehicle cannot be obtained in time, and it is difficult to achieve precise control to achieve the purpose of adjustment

The invention provides an oil temperature and oil pressure control device and a method thereof for vehicles. The oil temperature and oil pressure control device comprises a controller, a cooling unit, a temperature sensor and an LM317L voltage stabilizing chip, wherein a Vout terminal of the LM317L voltage stabilizing chip is connected with an ADJ terminal through an adjustable resistor; a first end of the adjustable resistor is connected with the Vout terminal of the LM317L voltage stabilizing chip, and a second end is connected with the ADJ terminal and the temperature sensor; and the input end of the controller is connected with the temperature sensor and used for receiving voltage passing through two ends of the temperature sensor, and the output end is connected with the cooling unit. According to the oil temperature and oil pressure control device and method thereof for the vehicles, the LM317L voltage stabilizing chip is used to output adjustable current to test the temperature and the resistance of a pressure sensor, and the controller controls the working state of the cooling unit or an engine according to the temperature and the resistance value of the pressure sensor, so that dynamic control of the oil temperature and the oil pressure of an oil tank is achieved.
Description
technical field [0001] The invention belongs to the technical field of vehicle control, and in particular relates to a vehicle oil temperature and oil pressure control device and a method thereof. Background technique [0002] The oil temperature and oil pressure of the vehicle are an important physical parameter of the vehicle, especially on engineering vehicles. Once these physical parameters change greatly, it will affect the working state of the vehicle and even cause damage to the vehicle. . [0003] Most of the existing technology is through the naked eye observation and on-site observation of technicians, but due to the limitation of the working environment, there are errors in the observation of technicians, and these parameters of the vehicle cannot be obtained in time, and it is difficult to achieve precise control to achieve the purpose of adjustment . [0004] Therefore, it is necessary to design an automatic control device for oil temperature and oil pressure ...
