Description
技术领域technical field
本发明涉及汽车技术领域，特别是涉及一种自动变速器车辆驾驶性标定测试油门控制方法及系统。The invention relates to the technical field of automobiles, in particular to a throttle control method and system for an automatic transmission vehicle drivability calibration test.
背景技术Background technique
出于成本、可靠性及技术实现难度的考虑，很多压力、扭矩、温度及位置传感器无法在整车或动力总成中布置，使得很多关键控制系统无法完全做到闭环控制，目前自动变速器控制单元(即TCU，Transmission Control Unit)内部使用的大部分控制参数都需要标定工程师根据整车驾驶性目标对其进行在线调整，即TCU整车标定。Due to the consideration of cost, reliability and difficulty in technical realization, many pressure, torque, temperature and position sensors cannot be arranged in the vehicle or powertrain, making many key control systems unable to fully achieve closed-loop control. At present, the automatic transmission control unit Most of the control parameters used inside (ie TCU, Transmission Control Unit) need to be adjusted online by the calibration engineer according to the vehicle drivability target, that is, TCU vehicle calibration.
在TCU整车驾驶性标定过程中，通常需要对不同定油门的驾驶工况的驾驶性进行标定测试。目前对于不同定油门的驾驶工况操作基本上都是通过标定工程师的驾驶经验来达到油门的稳定性和精度要求，这对于驾驶员的要求极严格，在驾驶性标定过程中标定工程师在驾驶过程中同时还需要兼顾驾驶性主观评价，为了保证定油门精度和稳定性使得标定工程师易造成评价分析的不准确。目前，对于油门控制方式有两种，第一种是通过设计特定的油门位置控制装置安装在油门踏板上，通过拉索和固定杆对油门踏板行程进行固定从而得到不同的油门开度；第二种是通过电子油门信号发生器对油门踏板电压信号进行精确控制，进而得到所需的油门开度。然而，这两种方式均不能根据驾驶员的需求变化实时切换至车辆油门踏板控制油门开度方式，因此仅可用于在台架上的车辆测试验证中的油门开度控制。In the process of TCU vehicle drivability calibration, it is usually necessary to perform a calibration test on the drivability of different throttle settings. At present, the driving conditions of different throttle settings are basically based on the driving experience of the calibration engineer to meet the stability and accuracy requirements of the throttle, which is extremely strict for the driver. At the same time, it is also necessary to take into account the subjective evaluation of drivability. In order to ensure the accuracy and stability of the throttle setting, the calibration engineer is likely to cause inaccurate evaluation and analysis. At present, there are two ways to control the accelerator. The first is to install a specific accelerator position control device on the accelerator pedal, and fix the stroke of the accelerator pedal through a cable and a fixed rod to obtain different accelerator openings; the second The first is to precisely control the accelerator pedal voltage signal through the electronic accelerator signal generator, and then obtain the required accelerator opening. However, neither of these two methods can be switched to the vehicle accelerator pedal to control the accelerator opening in real time according to the change of the driver's demand, so they can only be used for the accelerator opening control in the vehicle test verification on the bench.

具体实施方式Detailed ways
为更进一步阐述本发明为达成预定发明目的所采取的技术方式及功效，以下结合附图及实施例，对本发明的具体实施方式、结构、特征及其功效，详细说明如后。In order to further explain the technical means and effects of the present invention to achieve the intended purpose of the invention, the specific implementation, structure, features and effects of the present invention will be described in detail below in conjunction with the accompanying drawings and examples.
如图1所示，为本发明第一实施例提供一种自动变速器车辆驾驶性标定测试油门控制方法，该方法包括以下步骤：As shown in Figure 1, a kind of automatic transmission vehicle drivability calibration test throttle control method is provided for the first embodiment of the present invention, and the method comprises the following steps:
S10，判断油门踏板是否被操作、刹车踏板是否被操作、车辆是否达到预设车速以及外部开关是否被开启，当油门踏板被操作、刹车踏板被操作、车辆达到预设车速及外部开关未被开启中的任意一个条件达成时，控制以车辆油门踏板控制油门开度模式控制油门开度，否则进入步骤S16。S10, judging whether the accelerator pedal is operated, whether the brake pedal is operated, whether the vehicle reaches the preset speed and whether the external switch is turned on, when the accelerator pedal is operated, the brake pedal is operated, the vehicle reaches the preset speed and the external switch is not turned on When any one of the conditions is met, control the accelerator opening in the mode of vehicle accelerator pedal controlling the accelerator opening; otherwise, go to step S16.
具体地，油门踏板是否被操作、刹车踏板是否被操作、车辆是否达到预设车速的信号都可通过车载自动诊断系统(OBD，On Board Diagnostics)获取，而外部开关是否开启的状态是通过硬线进行采集。车辆油门踏板控制油门开度模式是指通过驾驶人踩踏油门踏板来控制油门开度的油门控制模式。Specifically, the signals of whether the accelerator pedal is operated, whether the brake pedal is operated, and whether the vehicle has reached a preset speed can be obtained through the on-board automatic diagnostic system (OBD, On Board Diagnostics), while the state of whether the external switch is turned on is determined by hardwired to collect. The vehicle accelerator pedal control accelerator opening mode refers to an accelerator control mode in which the driver steps on the accelerator pedal to control the accelerator opening.
S16，检测是否有语音输入，如果是，进入步骤S17。当然，语音输入也可由其他输入方式代替，例如键盘输入或触控屏输入，借此输入油门开度指令。相比其他输入方式，语音输入不需要驾驶人的手进行操作，只需要发音即可，不仅十分方便，也进一步保证了驾驶的安全性。S16. Detect whether there is voice input, and if yes, go to step S17. Of course, the voice input can also be replaced by other input methods, such as keyboard input or touch screen input, so as to input the throttle opening command. Compared with other input methods, voice input does not require the driver's hands to operate, but only requires pronunciation, which is not only very convenient, but also further ensures driving safety.
S17，识别语音输入，并转换成油门开度需求值。油门开度需求值例如可以为10％、20％、30％......95％等，可根据需要设置，语音输入为“30”时，系统识别该语音输入，并转化成油门开度需求值为打开油门最大开度的30％。当键盘输入或触控屏输入时，可在键盘或触控屏上设置10％、20％等不同按键，按压相应按键则对应输入不同油门开度需求值命令。本实施例中，语音识别模块中的语音识别准确率应超过95％，语音识别结果响应时间低于200ms。S17, recognize the voice input, and convert it into a demand value of the throttle opening. The required value of throttle opening can be 10%, 20%, 30%...95%, etc., which can be set according to the needs. When the voice input is "30", the system will recognize the voice input and convert it into throttle opening value. The degree demand value is 30% of the maximum opening degree of the throttle. When keyboard input or touch screen input, different buttons such as 10% and 20% can be set on the keyboard or touch screen, and pressing the corresponding button will correspondingly input different throttle opening demand value commands. In this embodiment, the speech recognition accuracy rate in the speech recognition module should exceed 95%, and the response time of the speech recognition result should be less than 200ms.
S18，根据该油门开度需求值自动控制油门开度。具体地，可在系统内预设油门开度需求值表，判断转换后的油门开度需求值与油门开度需求值表中的值是否对应，当转换后的油门开度需求值与油门开度需求值表中的值对应时，根据该油门开度需求值自动控制油门开度；当转换后的油门开度需求值在油门开度需求值表中没有对应值时，不执行自动控制油门开度的动作，系统提示再次进行语音输入。S18, automatically controlling the throttle opening according to the demand value of the throttle opening. Specifically, the throttle opening demand value table can be preset in the system to determine whether the converted throttle opening demand value corresponds to the value in the throttle opening demand value table. When the value in the throttle opening demand value table corresponds, the throttle opening is automatically controlled according to the throttle opening demand value; when the converted throttle opening demand value does not have a corresponding value in the throttle opening demand value table, automatic control of the throttle is not performed. Opening action, the system prompts to perform voice input again.
具体地，步骤S10包括以下步骤：Specifically, step S10 includes the following steps:
S11，判断油门踏板是否被操作，如果是，进入步骤S12，如果否，进入步骤S13。具体的，油门踏板被踩下时可认为油门踏板被操作。S11, determine whether the accelerator pedal is operated, if yes, go to step S12, if not, go to step S13. Specifically, when the accelerator pedal is depressed, it may be considered that the accelerator pedal is operated.
S12，控制以车辆油门踏板控制油门开度方式控制油门开度。这时，汽车油门开度由驾驶人踩踏油门踏板直接控制，进入常规的汽车驾驶状态。S12, controlling the accelerator opening in the manner of controlling the accelerator opening by the accelerator pedal of the vehicle. At this time, the accelerator opening of the car is directly controlled by the driver stepping on the accelerator pedal, and the vehicle enters a normal driving state.
S13，判断刹车踏板是否被操作，如果是，进入步骤S12，如果否，进入步骤S14。具体的，刹车踏板被踩下时可认为刹车踏板被操作。S13, judging whether the brake pedal is operated, if yes, go to step S12, if not, go to step S14. Specifically, when the brake pedal is depressed, it may be considered that the brake pedal is operated.
S14，判断车辆是否达到预设速度，如果是，进入步骤S12，如果否，进入步骤S15。该预设速度为预先设定的车辆的测试最高车速，当达到该预设速度时，油门开度由车辆油门踏板控制。S14, judging whether the vehicle has reached the preset speed, if yes, go to step S12, if not, go to step S15. The preset speed is the preset maximum speed of the vehicle for testing, and when the preset speed is reached, the accelerator opening is controlled by the accelerator pedal of the vehicle.
S15，判断外部开关是否开启，如果是，进入步骤S16，如果否，进入步骤S12。外部开关为控制开启或关闭油门开度自动控制方式的开关，只有外部开关开启方可实现油门开度自动控制。S15, judge whether the external switch is turned on, if yes, go to step S16, if not, go to step S12. The external switch is a switch for controlling the opening or closing of the automatic control mode of the throttle opening, and the automatic control of the throttle opening can be realized only when the external switch is turned on.
可以理解，上述步骤S11、S13、S14和S15并无先后顺序的要求，其顺序既可调换，也可同时进行。It can be understood that the above steps S11 , S13 , S14 and S15 have no sequence requirement, and the sequence can be reversed or performed simultaneously.
在本自动变速器车辆驾驶性标定测试油门控制方法中，油门开度的控制有两种控制模式，一种是通过语音输入后转换成油门开度需求值，并据此控制油门开度，实现对油门开度的自动控制，另一种是通过车辆油门踏板控制油门开度。In this automatic transmission vehicle drivability calibration test throttle control method, there are two control modes for the control of the throttle opening, one is to convert the demand value of the throttle opening through voice input, and control the throttle opening accordingly to realize the control of the throttle opening. The other is the automatic control of the accelerator opening, and the other is to control the accelerator opening through the vehicle accelerator pedal.
通过本发明的自动变速器车辆驾驶性标定测试油门控制方法，可以精确地控制油门开度，实现在实际驾驶过程中的TCU整车标定测试，同时当出现油门踏板被踩下、刹车踏板被踩下或车辆超过预设车速时可自动切换至由油门踏板控制油门开度的正常的驾驶状态，使驾驶人可随时掌控车辆，保证了复杂路况下的驾驶安全性，从而使驾驶人可以专注车辆驾驶过程以及驾驶工况主观评价，提高了TCU整车标定效率，缩短标定开发周期。Through the throttle control method of the automatic transmission vehicle drivability calibration test of the present invention, the throttle opening can be accurately controlled, and the TCU vehicle calibration test in the actual driving process can be realized. Or when the vehicle exceeds the preset speed, it can automatically switch to the normal driving state where the accelerator opening is controlled by the accelerator pedal, so that the driver can control the vehicle at any time, ensuring driving safety under complex road conditions, so that the driver can focus on driving the vehicle The subjective evaluation of the process and driving conditions improves the efficiency of TCU vehicle calibration and shortens the calibration development cycle.

The throttle opening demand value table can be preset in the control module 10, and when the converted throttle opening demand value corresponds to the value in the throttle opening demand value table, the throttle opening is automatically controlled according to the throttle opening demand value; When the converted throttle opening demand value has no corresponding value in the throttle opening demand value table, the action of automatically controlling the throttle opening is not executed, and the system prompts voice input here.
输入模块12可为语音输入模块，语音输入模块用于检测是否有语音输入，并识别语音输入，将其转换成油门开度需求值。当然，语音输入模块也可由其他输入模块代替，例如键盘输入模块或触控屏输入模块。油门开度需求值例如可以为10％、20％、30％......95％等，可根据需要设置，语音输入为“30”时，系统识别该语音输入，并转化成油门开度需求值为打开油门最大开度的30％。当键盘输入或触控屏输入时，可在键盘或触控屏上设置10％、20％等不同按键，按压相应按键则对应输入不同油门开度需求值命令。本实施例中，语音识别模块中的语音识别准确率应超过95％，语音识别结果响应时间低于200ms。The input module 12 can be a voice input module, and the voice input module is used to detect whether there is a voice input, recognize the voice input, and convert it into a demand value of the throttle opening. Of course, the speech input module can also be replaced by other input modules, such as a keyboard input module or a touch screen input module. The required value of throttle opening can be 10%, 20%, 30%...95%, etc., which can be set according to the needs. When the voice input is "30", the system will recognize the voice input and convert it into throttle opening value. The degree demand value is 30% of the maximum opening degree of the throttle. When keyboard input or touch screen input, different buttons such as 10% and 20% can be set on the keyboard or touch screen, and pressing the corresponding button will correspondingly input different throttle opening demand value commands. In this embodiment, the speech recognition accuracy rate in the speech recognition module should exceed 95%, and the response time of the speech recognition result should be less than 200ms.
