The method can be realized by a computer program and can be run on a throttle pattern self-adaptive identification device based on a von neumann system. The computer program may be integrated in the application or may run as a stand-alone tool class application.
Referring to fig. 1, a flow chart of an adaptive recognition method for an accelerator mode is provided in an embodiment of the present application. As shown in fig. 1, the method according to the embodiment of the present application may include the following steps:
s101, acquiring the idle speed switch state quantity of a current vehicle and the accelerator hard wire input voltage parameter in real time;
The current idle speed switch of the vehicle is a low idle speed switch, the low idle speed switch is closed when an accelerator signal is zero (for example, the engine runs at low idle speed), the value is 1, the low idle speed switch is used for checking whether the accelerator zero point drifts, an accelerator hard wire is a circuit of the accelerator, and the accelerator hard wire input voltage parameters comprise a first accelerator hard wire input voltage value and a second accelerator hard wire input voltage value.
In the embodiment of the application, when the throttle mode self-adaptive identification is performed, firstly, the idle speed switch state quantity of the current vehicle is acquired in real time, and then the first throttle hard wire input voltage value and the second throttle hard wire input voltage value of the current vehicle are acquired to obtain the throttle hard wire input voltage parameter.

In the embodiment of the application, when the priority of each preset accelerator mode in a plurality of preset accelerator modes is acquired, firstly, the weight value of each preset accelerator mode in the plurality of preset accelerator modes is acquired, and then the priority of each preset accelerator mode is determined according to the weight value of each preset accelerator mode.
In the embodiment of the application, when the priority of each preset accelerator mode in a plurality of preset accelerator modes is acquired, the use frequency of each preset accelerator mode in the plurality of preset accelerator modes is firstly acquired, and then the priority of each preset accelerator mode is determined according to the use frequency of each preset accelerator mode.
In the embodiment of the application, when determining the mode judgment order based on the priority order, the plurality of preset throttle modes are ordered according to the priority order to obtain the ordered plurality of preset throttle modes, and then the judgment sequence numbers are marked one by one for the ordered plurality of preset throttle modes to obtain the mode judgment order.
In one possible implementation, after determining the idle switch state quantity of the current vehicle and the accelerator hard line input voltage parameter based on step S101, a priority of each of the plurality of preset accelerator modes may be obtained, and the mode judgment order may be determined based on the priority order.
S103, identifying a target accelerator mode of the current vehicle according to the mode judging sequence, the idle speed switch state quantity and the accelerator hard wire input voltage parameter.
Typically, the mode determination sequence is a dual mode plus low idle switch mode, a dual mode, a single mode, and a CAN bus mode in order.
In the embodiment of the application, when the target accelerator mode of the current vehicle is identified according to the mode judgment sequence, the idle speed switch state quantity and the accelerator hard wire input voltage parameter, whether the target accelerator mode of the current vehicle is a dual-mode low idle speed switch mode, a dual-mode, a single-mode or a CAN bus mode CAN be judged in sequence according to the idle speed switch state quantity and the accelerator hard wire input voltage parameter.
Specifically, when judging whether the target accelerator mode of the current vehicle is a dual-mode low-idle-speed switch mode, a dual-mode, a single-mode or a CAN bus mode according to the idle switch state quantity and the accelerator hard wire input voltage parameter in sequence, and when the idle switch state quantity changes and the first accelerator hard wire input voltage value and the second accelerator hard wire input voltage value are respectively located in a preset voltage effective value interval, determining that the target accelerator mode of the current vehicle is the dual-mode low-idle-speed switch mode; or when the idle speed switch state quantity is unchanged and the second accelerator hard line input voltage value is in a preset voltage effective value interval, determining that the target accelerator mode of the current vehicle is a dual-mode; or when the idle speed switch state quantity is unchanged, the first accelerator hard wire input voltage value is located in a preset voltage effective value interval, and the second accelerator hard wire input voltage value is not located in the preset voltage effective value interval, determining that the target accelerator mode of the current vehicle is a single-mode; or when the idle speed switch state quantity is unchanged, the first accelerator hard wire input voltage value and the second accelerator hard wire input voltage value are not respectively located in a preset voltage effective value interval, and the existence of an accelerator message is detected, determining that the target accelerator mode of the current vehicle is a CAN bus mode.
For example, as shown in fig. 2, fig. 2 is a schematic block diagram of a mode recognition flow provided by the present application, when a first accelerator hard line input voltage value U1, a second accelerator hard line input voltage value U2, and a preset voltage effective value interval [ Max, min ] are obtained, a dual mode low idle switch mode, a dual mode, a single mode, and a CAN bus mode CAN be sequentially determined according to a determined mode determination order. When the idle speed switch state quantity changes, U2 is in [ Max, min ] and U1 is in [ Max, min ], determining that the target throttle mode of the current vehicle is a dual-mode low idle speed switch mode; or when the idle speed switch state quantity is unchanged and U2 is in [ Max, min ], determining that the target throttle mode of the current vehicle is a dual-mode; or when the idle speed switch state quantity is unchanged, U2 is not in [ Max, min ] and U1 is in [ Max, min ], determining that the target throttle mode of the current vehicle is a single-mode; or when the throttle message value is detected to be larger than 0 under the conditions that the idle speed switch state quantity is unchanged, U2 is not in [ Max, min ] and U1 is not in [ Max, min ], determining that the target throttle mode of the current vehicle is a CAN bus mode.
Further, after the identified target accelerator mode is obtained, firstly, the identified target accelerator mode is sent to a result judging terminal, a mode judging result from the result judging terminal is received, and then the current vehicle operation is controlled according to the mode judging result; or firstly, acquiring the last historical target throttle mode in the latch, then carrying out logic operation according to the identified target throttle mode and the historical target throttle mode, outputting a fault judgment result, and finally controlling the current vehicle to run according to the fault judgment result.
Specifically, the result determination terminal includes a driver instrument and a message detection device.
For example, as shown in fig. 3, fig. 3 is a schematic flow chart of determining an identified target accelerator mode provided by the application, after the identified target accelerator mode is obtained, the identified target accelerator mode is sent to a driver instrument for display, so that a driver can determine whether a result is accurate or not, and the driver can input a determination result after the determination is finished. Or the message related to the target throttle mode is sent to message detection equipment for the detection equipment to generate a verification result after the accuracy of the result is verified.
Specifically, when a fault judgment result is output by performing logic operation according to the identified target accelerator mode and the historical target accelerator mode, first acquiring a first priority of the identified target accelerator mode, then acquiring a second priority of the historical target accelerator mode, then calling a fault logic service corresponding to the identified target accelerator mode when the first priority is higher than the second priority, and finally performing logic calculation according to the fault logic service corresponding to the identified target accelerator mode to generate and output the fault judgment result. Or when the second priority is higher than the first priority, calling the fault logic service corresponding to the historical target accelerator mode, and finally carrying out logic calculation according to the fault logic service corresponding to the historical target accelerator mode to generate and output a fault judgment result.
For example, as shown in fig. 4, fig. 4 is a schematic diagram of a fault judging flow provided in the present application, firstly, after an identified target throttle mode is obtained, a last identified historical target throttle mode can be obtained, then, whether the priority of the currently identified throttle mode is higher than that of the historical target throttle mode is judged, when the priority of the currently identified throttle mode is higher than that of the historical target throttle mode, the current identified throttle mode can participate in logic operation, otherwise, the current identified throttle mode can participate in logic operation. When the logic operation is participated, a fault logic calculation strategy corresponding to the currently identified throttle mode or the historical target throttle mode can be called, and a fault judgment result can be calculated and output according to the corresponding strategy. The fault logic calculation strategy comprises a dual-mode low-idle-speed switch mode fault logic, a dual-mode fault logic, a single-mode fault logic and a CAN (controller area network) mode fault logic respectively.
In the embodiment of the application, the throttle mode self-adaptive recognition device firstly collects the idle speed switch state quantity and the throttle hard line input voltage parameter of the current vehicle in real time, then obtains the priority of each preset throttle mode in a plurality of preset throttle modes, determines the mode judgment sequence based on the priority order, and finally recognizes the target throttle mode of the current vehicle according to the mode judgment sequence, the idle speed switch state quantity and the throttle hard line input voltage parameter. According to the application, the target throttle mode of the current vehicle can be rapidly judged by collecting the idle speed switch state quantity of the current vehicle and the throttle hard line input voltage parameters in real time and combining the priority of each preset throttle mode in a plurality of preset throttle modes, so that the problem that an ECU supplier needs to process different throttle modes when aiming at multiple order numbers is avoided, and the working efficiency is improved.
