[0035] Beneficial effects: Through this wireless intelligent valve control module, except for the signal recognition module CAN line transfer and power supply, no other wiring is required, and no other interior decoration needs to be disassembled, which reduces the difficulty of wiring and saves installation time. When the roaring mode is selected, the vehicle opens the valve in advance before starting, and the selected start time is timed at the moment of starting, so that the burst sound of the vehicle starting at the moment is emitted through the exhaust. Compared with other brands, the valve is opened at the moment of vehicle starting, resulting in a better sound after the delay. At the same time, after the engine runs the selected roaring mode start time, it automatically returns to the pre-mode. And when the intelligent valve start-stop module turns off the intelligent valve module, the vehicle follows the valve closing logic of the original mode. If the owner floor gas in this mode, the valve will still release the engine back pressure according to the original mode to avoid forcing the full closure of the valve to cause damage to the engine. At the same time, the core processing unit collects data from the vehicle using the wireless intelligent valve module, and then analyzes and processes the collected data to obtain the corresponding analysis and processing results, and obtains the remote setting signal transmitted by the remote setting unit. At the same time, when obtaining the remote setting signal transmitted by the remote setting unit, setting suggestions are given according to the analysis and processing results, which can provide reference for users when performing remote settings.

[0040] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] Embodiment 1:

[0042] First, the signal recognition module of the processing control unit is used to identify the CAN bus signal of the original vehicle, including engine speed, driving mode, valve opening signal, etc.

[0043] Then, the wireless intelligent valve module selects the mode through the mode selection block of the remote setting unit, and sets whether the vehicle starts the roaring mode, the time to start the roaring mode and the vehicle valve opening through the original vehicle mode setting module, the speed mode setting module and the driving mode setting module according to the selected mode. The speed mode setting module and the driving mode setting module can be used in combination, that is, different vehicle valve opening angles can be set according to different speeds in different driving modes.

[0044] The signal conversion module of the processing and control unit then changes the data signals of the valve settings and transmits them to the vehicle control unit, which are received by the signal receiving module of the vehicle control unit and switched to the corresponding mode. The valve adjustment module adjusts the corresponding valve angle of the vehicle according to the valve angle data signal received by the signal receiving module and the corresponding switched mode.

[0045] If you choose to start the vehicle's roaring mode, the explosive sound will be emitted through the exhaust at the moment the vehicle starts according to the selected roaring mode time. Compared with other brands, the explosive sound after the vehicle start delay is better. After the roaring mode is started for the pre-selected time, the automatic recovery module of the control unit will automatically restore to the pre-selected vehicle mode.

[0046] At the same time, the smart valve module can be started and closed through the smart valve start-stop module. When the smart valve module is closed, the vehicle follows the valve closing logic of the original mode. If the owner steps on the gas in this mode, the valve will still release the engine back pressure according to the original mode to avoid damage to the engine caused by forcing the valve to be fully closed.

[0047] And when performing analysis and processing, the analysis and processing module can obtain the setting index of different valve openings in each setting option of the same vehicle based on the data about the number of vehicles, the data about the usage time and the usage history data collected by the data collection module about the vehicles using the wireless intelligent valve module:

[0048] ;

[0049] Therefore, according to the setting index of different valve openings in each setting option of the same vehicle, corresponding setting suggestions can be issued during remote setting. When the setting index of the valve opening selected by the remote setting unit is the highest, no suggestion is issued. When the setting index of the valve opening selected by the remote setting unit is not the highest, the highest corresponding valve opening suggestion among the setting indexes of different valve openings in the setting option of the same vehicle is issued to the remote setting module through the suggestion issuing module for the user to set whether to select the recommended valve opening setting or still use the valve opening selected by the user; wherein, is the setting index of different valve openings in each setting option of the same vehicle, N is the number of vehicles of the same model using the intelligent valve module, an is the number of vehicles of the same model using this valve opening, bn is the number of vehicles of the same model switching from other valve openings to this valve opening, cn is the number of vehicles of the same model switching from this valve opening to other valve openings, The usage time of each vehicle of the same model using the smart valve module, The usage time of each vehicle of the same model that uses this valve opening. is the usage time of each vehicle of the same model that switches from other valve openings to this valve opening, is the usage time of each vehicle of the same model that switches from this valve opening to other valve openings, For the driving history of each vehicle of the same model using the smart valve module, For the driving history of each vehicle of the same model that uses this valve opening, The driving history of each vehicle of the same vehicle type that switches from other valve openings to this valve opening, It is the driving history of each vehicle of the same vehicle model that switches from this valve opening to other valve openings.

[0050] Embodiment 2:

[0051] The customer wants to fully open the valves when idling to make the car sound sportier, but after driving, he wants to maintain the original 1000-3000 range or achieve better low torque at a certain angle.

[0052] Embodiment 3:

[0053] In some modes of BMW M, the valve will not fully open until 4000 rpm. Through this function, we can achieve full valve opening above 3000 rpm to make the exhaust smoother when flooring the gas.

[0054] Embodiment 4:

[0055] Mpower models can only use Comfort, Sport and Sport Plus modes corresponding to the three driving modes on the car, eco and comfortplus are invalid;

[0056] Comfort=Efficiency mode, in this mode, the factory is completely closed, regardless of whether the factory valve button switch is activated. In order to make the car more comfortable, it is recommended to keep the original factory, and low torque will also be better for normal driving;

[0057] Sport mode, the original idle speed is opened to 50%, and it is recommended to set it to 100% open;

[0058] Sport Plus mode, open 50% at the original idle speed, it is recommended to set it to 100 fully open.

[0059] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
