Detailed Description
The following description of the embodiments of the present invention will be made apparent and fully in view of the accompanying drawings, in which some, but not all embodiments of the invention are shown. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The flow chart of the statistical analysis method of the constant speed function data of the hydraulic retarder shown in fig. 1 comprises the following steps:
Step S1, monitoring whether the hydraulic retarder is in a constant speed function gear in real time, and if the hydraulic retarder is in the constant speed function gear, activating a constant speed function data statistical analysis function of the hydraulic retarder;
Step S2, acquiring a temperature signal, a vehicle running signal and a brake control signal in the constant-speed running process of the hydraulic retarder according to a preset sampling frequency, and carrying out average calculation (solving an average value), difference calculation or ratio calculation to obtain a constant-speed functional data calculation result of the hydraulic retarder;
Preferably, the collecting the temperature signal, the vehicle running signal and the brake control signal during the constant-speed running process of the hydrodynamic retarder according to the preset sampling frequency further comprises:
And acquiring a water temperature signal and an oil temperature signal of the hydraulic retarder according to a first preset sampling frequency, acquiring an actual vehicle speed signal of the whole vehicle, an engine brake intervention total time length signal, an exhaust brake intervention total time length signal, an engine brake intervention total frequency signal and an exhaust brake intervention total frequency signal according to a second preset sampling frequency, and storing the signals into a control unit of the hydraulic retarder.
For example, when the statistical method of the constant speed function data information of the hydraulic retarder is activated, the hydraulic retarder control unit selects the temperature sampling frequency f1=1hz in the implementation convenience according to the preset sampling frequency f1 and considers the temperature change characteristics, and collects the cooling water temperature signal and the oil temperature signal of the hydraulic retarder based on the temperature sampling frequency f 1. The hydraulic retarder control unit takes the sampling frequency f2=20hz according to the preset sampling frequency f2, taking the whole vehicle performance into consideration.
The hydraulic retarder control unit can influence the acquisition result in the process of acquiring signals by selecting different sampling frequencies, the sampling frequencies refer to how many times of signal sampling are carried out per second, the original signals can be restored more accurately by the higher sampling frequencies, but the data quantity and the processing complexity can be increased, for example, larger space can be occupied when internal storage and cloud storage are carried out, and the lower sampling frequencies can possibly lead to information loss or can not accurately restore the signals, and cannot obtain accurate cooling water temperature signals and oil temperature signals. The selection of the appropriate usage frequencies f1 and f2 in this embodiment is therefore based on the balance between the required accuracy and the resource consumption in terms of trade-off, which determines the appropriate usage frequencies f1 and f2 in connection with the specific application scenario and requirements.
The calculation method of the average oil temperature value is to solve the average of all oil temperature values acquired in one constant-speed operation interval of the hydraulic retarder, and the calculation method of the average cooling water temperature value of the hydraulic retarder is to solve the average of all cooling water temperature values acquired in one constant-speed operation interval of the hydraulic retarder.

The whole vehicle speed signal is obtained by the hydraulic retarder control unit collecting the rotating speed signal through the rotating speed sensor and then converting the rotating speed signal.
For example, for signal acquisition of the engine brake and the exhaust brake, the acquisition of the ERC message is performed through the CAN bus, and the number of times and the total time of the engine brake and the exhaust brake in a constant speed interval are calculated, and the total duration in the constant speed interval is acquired. And calculating the data acquired in the constant-speed operation process of the whole hydraulic retarder to obtain the average oil temperature value of the hydraulic retarder.

Preferably, according to the entering/exiting condition of the constant speed function of the hydraulic retarder during the running process of the vehicle, the statistical analysis of the constant speed function data of the hydraulic retarder is circularly performed, and the method further comprises the following steps:
detecting whether the constant speed function of the hydraulic retarder is changed, if so, after the hydraulic retarder enters the constant speed function mode again, the data stored in the hydraulic retarder cover the previous data and are used for ensuring the running speed of the control unit of the hydraulic retarder.
In the method for counting the constant-speed function data information of the hydrodynamic retarder, if the constant-speed function exit condition occurs, for example, the constant-speed function exit caused by the operations of the whole vehicle accelerator pedal activation, the brake pedal activation, the ABS activation and the like, one constant-speed operation interval is ended, all data statistics and calculation are completed, and the next constant-speed cycle is performed after the vehicle activates the constant-speed function again.
