[0039] The embodiments of the present application are described below in conjunction with the accompanying drawings. The terms used in the embodiment part of the present application are only used to explain the specific embodiments of the present application, and are not intended to limit the present application.

[0040] The embodiments of the present application are described below in conjunction with the accompanying drawings. It is known to those skilled in the art that with the development of technology and the appearance of new scenarios, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems.

[0041] The terms "first", "second", and the like in the specification and claims of the present application and the above drawings are used to distinguish similar objects, and do not necessarily indicate a specific order or sequence. It should be understood that the terms used in this way can be interchanged under appropriate circumstances, which is only a distinguishing way used in the description of the embodiments of the present application to describe the objects with the same attribute. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, so that the processes, methods, systems, products or devices containing a series of units do not have to be limited to those units, but can include other units not clearly listed or inherent to these processes, methods, products or devices.

[0042] The whole vehicle matching the AMT has different requirements for the engine starting torque during the starting process due to the complex real-time working conditions. In special working conditions such as large slope, heavy vehicle, marshland, sandy land, etc., the engine low-speed torque output is insufficient, which may cause starting failure, engine stall and other problems. At present, the throttle control of the natural gas engine is global control, and overall consideration is given to performance and emission and other factors. The problems shown by such strategy calibration are slow engine speed response during starting, concave, secondary starting and other problems, for example:

[0043] During starting, the driver usually steps on the accelerator pedal, at which time the accelerator opening increases, and the engine control unit (ECU) adjusts the throttle opening according to the accelerator opening and other sensor signals, so as to control the air amount entering the engine and adjust the engine torque. At the same time, the AMT (electrically controlled mechanical automatic transmission) selects the appropriate gear according to the engine speed and vehicle speed and other parameters to ensure smooth starting of the vehicle. However, if the accelerator opening increases during starting, but the throttle opening does not increase accordingly, it may indicate that the throttle control has a problem. Or, the engine torque fails to increase when needed, and the AMT control value of the speed is set too low, which causes the engine to fail to maintain the minimum speed and stall. In addition, if the vehicle speed does not increase at the starting moment, and the engine speed drops sharply, it may indicate that the clutch is not engaged well or the transmission system is slipping. Due to the hysteresis of the transmission control unit, it will easily cause problems such as stall and starting failure.

[0044] In order to solve the above problems, the embodiment of the present application provides a vehicle starting control method. The vehicle starting control method of the embodiment of the present application will be described in detail below with reference to the drawings.

[0045] Referring to Figure 1 , Figure 1 The flow of the vehicle starting control method provided by the embodiment of the present application is shown in Figure 1 The vehicle starting control method provided by the embodiment of the present application can include steps 101 to 103, which will be described in detail below.

[0046] Step 101, determine whether the vehicle meets the vehicle starting adjustment condition.

[0047] In one embodiment, in order to realize the smooth start of the whole vehicle, it is necessary to firstly determine whether the vehicle is in the start state and whether the control unit of the gearbox meets the adjustment under the start condition. Only when the vehicle is in the start state and the control mode of the control unit of the gearbox is the speed control mode, the corresponding subsequent adjustment of the throttle opening degree will be carried out, and in the non-start state, the normal throttle opening degree adjustment strategy can be executed. The control mode of the control unit of the gearbox is the speed control mode, which means that the operation of the gearbox is managed and controlled by the electronic control unit to ensure the power transmission efficiency and driving comfort of the vehicle. The control mode of the control unit of the gearbox also includes: sports mode (S mode) and manual mode (M mode). The sports mode enhances the acceleration performance of the vehicle, while the manual mode allows the driver to manually select the gear. These modes can be freely switched, and the control unit of the gearbox will analyze the operation rationality in the background to ensure that the gearbox will not be damaged. Here, when the electronic control unit of the gearbox is in the speed control mode, the automatic transmission can be realized by the electronic control unit of the vehicle, and then the automatic control is realized.

[0048] The determination of whether the vehicle is in the start state can be determined according to the vehicle state information. Since the start of the vehicle is a process of transmitting the engine power to the wheels by the clutch slip to overcome the road resistance and realize the transition from static to motion. According to the change of each state parameter in this transition process, it can be determined whether the vehicle is currently in the start state. For example, when the state of the vehicle meets the following conditions, it can be determined that the vehicle is in the start state:

[0049] The current gear is in the first preset range, the output shaft speed is less than or equal to the first preset value, the input shaft speed is greater than or equal to the second preset value, the clutch slip rate is in the second preset range, and the brake state parameter is the third preset value. The various preset ranges and preset values can be adjusted flexibly by those skilled in the art according to different vehicles, and will not be described here.

[0050] It can be understood that those skilled in the art can determine the vehicle start adjustment condition according to actual needs, which is not limited here.

[0051] Step 102, when it is determined that the vehicle meets the vehicle start adjustment condition, the initial value of the throttle opening degree is determined according to the vehicle start adjustment strategy.

[0052] In one embodiment, when it is determined that the vehicle is in the starting state and the control mode of the gearbox control unit is the rotational speed control, the initial value of the throttle opening degree can be determined from a special throttle calibration table according to the engine rotational speed and the torque of the vehicle, wherein the special throttle calibration table is obtained by modifying the original throttle calibration table, and each throttle opening degree value in the special throttle calibration table is not less than the corresponding throttle opening degree value in the original throttle calibration table. For example, refer to the table shown below:

[0053]

[0054] In the above table, the horizontal axis is the rotational speed of the engine, the vertical axis is the torque of the engine, and the values in the table are the throttle opening degree values. In actual operation, the throttle opening degree value can be determined from the table according to the corresponding rotational speed and torque. Since it is necessary to ensure the smooth starting of the vehicle, each throttle opening degree value in the special throttle calibration table is slightly larger than the value in the original throttle calibration table at the same rotational speed and torque, thereby providing more intake air and ensuring that the engine will not easily stall.

[0055] It should be noted that those skilled in the art can adjust the throttle opening degree values in the special throttle calibration table as needed, which is not limited herein.

[0056] Step 103, modifying the initial value of the throttle opening degree according to the modified parameter of the vehicle to obtain a modified value of the throttle opening degree, and controlling the throttle according to the modified value of the throttle opening degree.

[0057] In one embodiment, based on the initial value of the throttle opening degree, it is considered that in the working conditions of large slope, heavy vehicle, marshland, sandy land, etc., the low-speed torque output of the engine is insufficient, which can cause starting failure, engine stall and other problems. Here, the initial value of the throttle opening degree is further modified, wherein the modified parameter can be a modified coefficient obtained according to the corresponding working condition, the modified coefficient multiplied by the initial value of the throttle opening degree to obtain the modified value of the throttle opening degree, and the modified coefficient is greater than 1.

[0058] In actual application, when it is determined that the vehicle is in the starting state, the starting throttle control calibration is switched, and the throttle control is modified based on the current throttle, slope, load and other information. At the same time, the deviation between the AMT control rotational speed and the actual rotational speed of the engine is monitored in real time, and the throttle is further modified based on the deviation value. The starting ability of the vehicle is improved, and the problems of starting failure, engine stall and secondary starting are solved.

[0059] ​In some embodiments, to further ensure the success rate of vehicle starting, the initial value of the throttle opening degree can be corrected multiple times based on different correction parameters to improve the success rate of starting, wherein the correction parameters at least include two types of correction parameters. The correction of the initial value of the throttle opening degree based on the correction parameters of the vehicle to obtain the corrected value of the throttle opening degree can specifically include:

[0060] Step 11, determining the correction coefficient corresponding to each type of correction parameter according to the parameter value of each type of correction parameter.

[0061] Specifically, taking the use of two types of correction parameters as an example, wherein the first type of correction parameter includes at least one vehicle operating parameter, which includes throttle opening degree, vehicle weight, slope, gear and the like. The second type of correction parameter includes the actual speed of the engine and the control speed of the gearbox control unit. Since there is a gap between the control speed and the engine speed, it is necessary to minimize this gap and adjust the throttle opening degree according to the gap to make the control speed and the actual speed consistent as soon as possible.

[0062] Wherein the process of determining the correction coefficient corresponding to the first type of correction parameter according to the parameter value of the first type of correction parameter includes:

[0063] According to the parameter value of each vehicle operating parameter, the first correction coefficient corresponding to each vehicle operating parameter is determined. Each first correction coefficient is fused to obtain the correction coefficient corresponding to the first type of correction parameter.

[0064] Taking the throttle opening degree and the vehicle weight as an example, the determination of the throttle opening degree correction coefficient and the vehicle weight correction coefficient can be carried out according to the following table respectively:

[0065]

[0066] On the basis of determining the correction coefficient of the throttle opening degree and the vehicle weight correction coefficient , the two are multiplied to obtain the correction coefficient corresponding to the first type of correction parameter, that is × .

[0067] Similarly, the process of determining the correction coefficient corresponding to the second type of correction parameter according to the parameter value of the second type of correction parameter includes:

[0068] According to the difference between the first speed value and the second speed value, the correction coefficient corresponding to the second type of correction parameter is determined, wherein the first speed value is the parameter value of the actual speed and the second speed value is the parameter value of the control speed.

[0069] Specifically, refer to the table shown below:

[0070]

[0071] According to the rotational speed difference, the correction coefficient corresponding to the second correction parameter can be directly determined from the table .

[0072] Step 12, fusion processing is performed on each correction coefficient to obtain a fused correction coefficient.

[0073] On the basis of the above-mentioned correction coefficients, the correction coefficients are sequentially multiplied to obtain a final fused correction coefficient × × .

[0074] Step 13, the initial value of the throttle opening degree is corrected based on the fused correction coefficient to obtain a corrected value of the throttle opening degree.

[0075] On the basis of the fused correction coefficient, the initial value of the throttle opening degree is multiplied by the fused correction coefficient to obtain a corrected value of the throttle opening degree.

[0076] For example, the initial value of the throttle opening degree obtained by searching the special throttle calibration table through the rotational speed value and the torque value of the engine

[0077] is , according to the difference between the current control rotational speed and the actual rotational speed of the engine, the correction coefficient is obtained by table lookup , and according to the current throttle opening degree, the vehicle weight, etc., is obtained by table lookup , , and the final throttle opening degree value is = × × × .

[0078] Among them, each of the above-mentioned correction coefficients is generally a coefficient greater than 1, which can be adjusted according to the type of parameter, and the coefficient value in the table is not limited here.

[0079] It can be understood that the above is only an example of several correction parameters, and those skilled in the art can adjust the number of the above correction parameters according to the needs, which will not be repeated here.

[0080] In some other embodiments, when the vehicle is in a non-starting state, the original throttle control strategy can be restored, and then the normal throttle control state is restored after the vehicle starts smoothly, meeting the user's power demand.

[0081] The above introduces a vehicle starting control method provided by the embodiment of the application, and the following will introduce a device for executing the above-mentioned vehicle starting control method.
