The invention belongs to the technical field of vehicle control, and discloses an oil temperature obtaining method of a lubricating system, an automobile and a computer readable storage medium. The lubricating system can lubricate a four-wheel drive transmission system of a vehicle. The oil temperature obtaining method of the lubricating system comprises the steps that a first temperature value, a second temperature value and a third temperature value are obtained; the oil temperature of the lubricating system is calculated according to the first temperature value, the second temperature value and the third temperature value, the first temperature value is selected as the initial oil temperature of the lubricating system before the four-wheel-drive transmission system works, and the second temperature value is selected as the base oil temperature increased when the lubricating system lubricates the four-wheel-drive transmission system; the third temperature value is selected as a cooling oil temperature for cooling the lubrication system. According to the method, the oil temperature when the lubricating system lubricates and cools the four-wheel-drive system is calculated through simulation, so that the oil temperature does not need to be recognized through an oil temperature sensor, the oil temperature sensor can be removed to reduce the cost, and the four-wheel-drive transmission system can be prevented from being damaged due to failure of the oil temperature sensor.

    本发明属于车辆控制技术领域,公开了一种润滑系统的油温获取方法、汽车及计算机可读存储介质。该润滑系统能够润滑车辆的四驱传动系统,润滑系统的油温获取方法包括获取第一温度值,第二温度值及第三温度值;通过第一温度值、第二温度值及第三温度值计算润滑系统的油温,其中第一温度值被选取为四驱传动系统工作前的润滑系统的起始油温,第二温度值被选取为润滑系统润滑四驱传动系统时升高的基础油温,第三温度值被选取为使润滑系统冷却的冷却油温。本发明通过模拟计算润滑系统润滑并冷却四驱系统时的油温,从而无需通过油温传感器识别油温,不仅能够移除油温传感器以降低成本,而且能够避免因油温传感器失效而损伤四驱传动系统。
