The four-wheel drive system is a four-wheel drive system for short, improves the traction and the driving performance of the automobile, and gives consideration to the driving performance, the steering performance and the braking performance of the automobile. According to the different structures of the four-wheel drive system, the four-wheel drive system is divided into a pure mechanical four-wheel drive system, an electromagnetic four-wheel drive system and an electric control hydraulic four-wheel drive system. The electric control hydraulic four-wheel drive has the characteristics of low cost, small dragging torque, small noise and light weight, and is widely applied to high-end front four-wheel drive vehicles.
The electric control hydraulic four-wheel drive consists of a power takeoff connected with a gearbox, a transmission shaft and a torque manager rear drive module, wherein the torque manager is used as a key part for transmitting torque from a main drive shaft to an auxiliary drive shaft and consists of a control unit, an oil pump motor, a multi-plate clutch, clutch oil and a shell. During the process of torque transmission, the control unit drives the oil pump motor to pressurize clutch oil, and the clutch oil presses the multi-plate clutch to finish the transmission of torque.

This may cause the motor to continue to operate at a high rotational speed, causing motor failure, or the clutch plates to clamp up abnormally, and to operate for a long time under overload conditions and lack clutch oil lubrication, resulting in serious failures such as ablation.

The TBOX may acquire information of other components or systems, and send the information to the TSP through the network, thereby implementing communication between the vehicle 100 and the cloud server 200.
Fig. 2 is a flowchart illustrating a method for detecting a state of clutch oil according to an exemplary embodiment, and as shown in fig. 2, the method for detecting a state of clutch oil may be applied to a cloud server (such as the cloud server 200 shown in fig. 1), and includes the following steps.
Step S11: the method comprises the steps of obtaining running state information of a vehicle in a set time period and actual working current of an oil pump motor of a torque manager of the vehicle.

In an embodiment of the present disclosure, the torque manager is configured to transmit torque from a primary drive shaft to a secondary drive shaft of the vehicle, and the oil pump motor is configured to pressurize clutch oil in the torque manager to complete the transmission of torque.
In the disclosed embodiment, the vehicle may be a four-wheel drive system vehicle, such as vehicle 100 shown in fig. 1. The TBOX of the vehicle can acquire the running information of the vehicle in real time, the running information comprises running state information and actual working current of an oil pump motor of a torque manager, and after the information of set duration (such as 1 minute, 30 seconds and the like) is acquired, the information can be packaged and sent to a cloud server. In the embodiment of the disclosure, the vehicle may send the information in the set duration according to the set period, for example, the set period is 1 minute, then after the vehicle is powered on and operated, the TBOX may store each piece of information, and send all pieces of information accumulated in this minute to the cloud server every other minute, at this time, the set duration is also 1 minute.
The cloud server may continuously receive information sent by the vehicle, wherein each set of information is information of the vehicle within a set time length. The cloud server can determine whether the running condition of the vehicle in the corresponding set duration belongs to the preset running condition according to the running state information included in the information sent by the vehicle, and the embodiment of the disclosure is not limited to the mode of determining the running condition, and possible modes are explained below.
Optionally, the driving state information includes at least one of vehicle lateral acceleration information, vehicle longitudinal acceleration information, wheel speed information, steering wheel angle information, engine torque information, accelerator pedal information, brake pedal information, and transmission gear information.
Optionally, the preset running condition is any one of a starting condition, an accelerating condition, a fast running condition, a braking condition and a turning condition.
For example, whether the vehicle is in a starting condition, an accelerating condition or a braking condition can be determined according to the transverse acceleration information and the longitudinal acceleration information in the running state information; or, for example, whether the vehicle is in a turning condition may be determined based on the steering wheel angle information in the running state information, and so on.
Different preset running conditions correspond to different standard current ranges, the standard current range may be a theoretical normal oil pump motor current value range of the vehicle under the corresponding running condition, may be a range value preset according to experience, or may be a range value calculated according to running state information under the corresponding working condition, and the embodiment of the present disclosure does not limit this. For example, the standard current range of the oil pump motor corresponding to the starting condition is a value range of A + -. DELTA.A, and the like.
If the cloud server determines that the running condition of the vehicle in a set time period belongs to the preset running condition according to the running state information of the vehicle in the set time period, the cloud server can further judge whether the actual working current of the oil pump motor of the vehicle in the set time period is in the standard current range corresponding to the running condition, if so, the working state of the clutch oil of the torque manager can be determined to be normal, otherwise, the clutch oil is abnormal.
The embodiment of the present disclosure is not limited to the manner of determining whether the actual working current of the oil pump motor is within the standard current range corresponding to the driving condition. For example, the average value of all the actual working current values in the set time period can be calculated, and then whether the average value is in the current range corresponding to the driving condition is judged; or for example, the standard current range may be a range corresponding to the current value of each point in the set time period, and then it may be determined whether the actual operating current value of each point in the set time period is in the corresponding current range, and so on.
Through the mode, whether the state of the clutch oil of the torque manager is normal can be judged visually by utilizing the working current of the oil pump motor, the monitoring of the state of the clutch oil is realized, and the fault of a vehicle caused by the abnormal clutch oil is avoided.
Optionally, the running state information of the vehicle within the set time period and the actual working current of the oil pump motor of the torque manager of the vehicle may be obtained by obtaining the running state information, the actual working current and the actual torque transmitted by the torque manager within the set time period. Then, whether the actual working current is within the standard current range corresponding to the running condition is detected, the standard torque range corresponding to the running condition can be determined according to the running condition, then a part of torque belonging to the standard torque range is determined from the actual torque, then a part of actual working current corresponding to the part of torque is determined, and finally whether the average value of the part of actual working current is within the standard current range is detected.
Each preset driving condition corresponds to a standard current range and a standard torque range respectively, the standard torque range can also be a relatively stable torque range of a theoretical vehicle under the corresponding driving condition, and can be a range value preset according to experience or a range value calculated according to driving state information under the corresponding working condition, and the embodiment of the disclosure does not limit the range value. For example, the standard torque range of the oil pump motor corresponding to the starting condition is a value range of N ±. Δ N, and the like.
When the vehicle sends information, besides the running state information and the actual working current of the oil pump motor of the torque manager, the actual torque transmitted by the torque manager in the set time length is sent. Referring to fig. 3, the TBOX of the vehicle may package and send the actual operating current of the oil pump motor sent by the torque manager within a set time period, the actual torque transmitted by the torque manager, and the driving state information sent by each component or system of the vehicle (including, for example, acceleration information and wheel speed information sent by the ESP, steering wheel angle information sent by the EPS, engine torque information and accelerator brake pedal information sent by the EMS, and transmission gear information sent by the TCU) to a TSP (cloud server).
After receiving the information, the cloud server may determine the driving condition of the vehicle within a set time period according to the driving state information, for example, determine that the driving condition of the vehicle is a starting condition, then determine a standard current range and a standard torque range of a torque manager corresponding to the starting condition, then determine a partial torque belonging to the standard torque range from the received actual torque transmitted by the vehicle torque manager within the set time period, where the partial torque is a relatively stable torque, then determine a partial actual working current of the oil pump motor corresponding to the partial torque, average the partial actual working current, and finally determine whether the average value of the partial actual working current is within the standard current range.
Optionally, if the detection result shows that the average value of part of the actual working current is within the standard current range, determining that the state of the clutch oil is normal; if the detection result shows that the average value of part of the actual working current is higher than the standard current range, the working capacity of the oil pump motor is large, and the oil quantity of the clutch oil is determined to be insufficient; if the detection result shows that the average value of part of actual working current is lower than the standard current range, the friction of the clutch oil is increased, and water or other impurities are possibly more, so that the clutch oil is determined to contain the impurities.
Through the mode, whether the clutch oil of the vehicle is in a normal state, the oil quantity is insufficient or the impurity content is high can be detected well, and the method is favorable for preventing the vehicle from generating faults due to the abnormal clutch oil.
Optionally, when the state of the clutch oil is detected to be insufficient oil or contain impurities, a prompt message may be sent to the vehicle to prompt a driver of the vehicle to process the clutch oil.
Namely, if the cloud server detects that the clutch oil of the vehicle is abnormal, prompt information can be sent to the vehicle, so that a driver can timely process the clutch oil, and vehicle faults are avoided. Of course, the cloud server may also send information to the dealership of the vehicle so that the dealership may provide further services to the vehicle.
Optionally, the standard current range and the standard torque range corresponding to the preset running condition are corrected according to the acquired big data of other vehicles with the same vehicle model.
The big data may include actual torques transmitted by the torque managers for various periods, actual operating currents of oil pump motors of the torque managers, driving state information of the vehicle, and the like, which are transmitted by a large number of other vehicles. The cloud server may acquire a large amount of information of different vehicle types, and in order to improve detection accuracy and reduce false alarm rate, the cloud server may correct the standard current range and the standard torque range of each preset driving condition according to the big data of other vehicles of the same vehicle type.
