Description
[ technical field ]
The invention relates to the technical field of automobile testing, in particular to an automatic testing system and method for an active air inlet grille motor.
[ background art ]
An air inlet grille of the fuel vehicle is positioned right in front of a vehicle head and mainly used for providing two effects of air inlet and heat dissipation for an engine. In a common vehicle model, the air inlet grille door is always open, and the vehicle has the advantages that the engine can bear the maximum heat dissipation power only by starting the vehicle, and the vehicle is beneficial in hot summer, but not beneficial in winter on icy and snowy ground. If the air inlet grille is not closed, when a cold vehicle runs, air entering from the air inlet grille can cool a water tank with low temperature, and the water temperature is slowly increased directly, so that the engine is influenced to enter the optimal working state more quickly. The active air inlet grid fence can well solve the problem, and the air inlet grid can automatically adjust the opening degree according to the actual situation to control air inlet and heat dissipation. For example, the vehicle can be quickly warmed up in winter, and because the grille is in a closed state during cold start, the heat in the engine compartment is not easily dissipated, so that the preheating time can be shortened, and the engine can be quickly brought into an optimal working state. Meanwhile, the engine oil resistance is large in the low-temperature state, the engine oil temperature rises more slowly than the water temperature, and the temperature rise of the engine oil of the engine and the engine oil of the gearbox are accelerated in the grid closing state, so that the vehicle can enter the optimal working state more quickly. In addition, when the vehicle travels at a higher speed, strong wind resistance becomes the main cause of fuel consumption, and the active air intake grille can be properly closed, which can bring a lower wind resistance coefficient for the vehicle, thereby improving the stability and fuel economy of the vehicle.
The core component for controlling the grille action is an active air inlet grille motor. The active air inlet grille motor adopts a control mode of ECU and motor as the existing electromechanical integration system, wherein the ECU is internally provided with a communication module for receiving a control command to make the motor act and transmitting various state parameters of the motor to a vehicle body controller, and the communication modes commonly used on vehicles comprise CAN communication and LIN communication. In the test, therefore, the motor cannot be controlled simply using conventional switching commands, but a communication module is connected to it and a large amount of status information of the motor itself can be obtained via this module. Meanwhile, the electrical characteristics, such as current and voltage information, need to be collected through a commonly-used multimeter, oscilloscope or collector, and the motor needs to be controlled in various ways in the electrical test process to obtain performance parameters of the motor in different states. Therefore, the testing of such motors is more complicated than the testing of the traditional motors, the system needs to be built by connecting the traditional power supply and the traditional testing equipment to the sample, and also needs to connect the communication line to the sample, and the operation is more troublesome. Moreover, because the electrical characteristic testing device and the communication module are two mutually independent systems, the information of the electrical characteristic testing device and the communication module is difficult to synchronize in the test, namely the current and voltage information and the state information of the motor are difficult to be in one-to-one correspondence, so that the data obtained by the test is not comprehensive; moreover, because the tester needs to separately operate the communication equipment and the electrical performance testing equipment, the automation degree of the test is low.
At present, the supplier of general communication equipment on the market only provides communication equipment, and the supplier of electrical performance testing equipment only provides electrical performance testing equipment, and almost no equipment breaks through the two isolated data chains to obtain a solution combining two into one. Therefore, it would be of great significance to provide an active grille motor automatic test system to fill this gap, and the system could also be used in other electromechanical tests with communication control.
