The throttle mode adaptive identification method provided by the embodiment of the present application will be described in detail below with reference to fig. 1 to 4. The method may be implemented in dependence on a computer program, operable on a von neumann architecture based throttle mode adaptive recognition device. The computer program may be integrated into the application or may run as a separate tool-like application.
Referring to fig. 1, a schematic flow chart of a method for adaptively identifying a throttle mode is provided in an embodiment of the present application. As shown in fig. 1, the method of the embodiment of the present application may include the following steps:
s101, acquiring idle speed switch state quantity and accelerator hard-wire input voltage parameters of a current vehicle in real time;
the idle switch of the current vehicle is a low-idle switch, the low-idle switch is closed when an accelerator signal is zero (for example, an engine runs at a low idle speed), the value of the low-idle switch is 1, the low-idle switch is used for verifying whether the zero point of the accelerator 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 priority of each preset accelerator mode in the plurality of preset accelerator modes is obtained, the weight value of each preset accelerator mode in the plurality of preset accelerator modes is obtained first, 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 throttle mode in the plurality of preset throttle modes is obtained, the use frequency of each preset throttle mode in the plurality of preset throttle modes is obtained firstly, and then the priority of each preset throttle mode is determined according to the use frequency of each preset throttle mode.
In the embodiment of the application, when the mode judgment order is determined based on the priority level sequence, the preset throttle modes are sequenced according to the priority level sequence to obtain the sequenced preset throttle modes, and then the judgment serial numbers are marked one by one according to the sequenced preset throttle modes to obtain the mode judgment order.
In a possible implementation manner, after the idle switch state quantity and the accelerator hard-wire input voltage parameter of the current vehicle are determined based on step S101, the priority of each preset accelerator mode in the plurality of preset accelerator modes may be acquired, and the mode determination order may be determined based on the order of the priorities.
And S103, identifying a target accelerator mode of the current vehicle according to the mode judgment sequence, the idle speed switch state quantity and the accelerator hard wire input voltage parameter.
Generally, 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 this order.
In the embodiment of the application, when the target throttle mode of the current vehicle is identified according to the mode judgment sequence, the idle speed switch state quantity and the throttle hardwire input voltage parameter, whether the target throttle mode of the current vehicle is a dual-mode and low-idle speed switch mode or a dual-mode or a single-mode or a CAN bus mode CAN be sequentially judged according to the idle speed switch state quantity and the throttle hardwire input voltage parameter.
Specifically, when whether a target accelerator mode of the current vehicle is a dual-mode plus low-idle-speed switching mode or a dual-mode or a single-mode or a CAN bus mode is sequentially judged according to the idle speed switching state quantity and the accelerator hard-wire input voltage parameters, and when the idle speed switching 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, the target accelerator mode of the current vehicle is determined to be the dual-mode plus low-idle-speed switching mode; or when the idle switch state quantity is not changed and the second accelerator hard wire input voltage value is within the preset voltage effective value range, determining that the current target accelerator mode of the vehicle is a dual-mode; or when the idle speed switch state quantity is not changed, 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 a preset voltage effective value interval, determining that the target accelerator mode of the current vehicle is a single mode; or when the idle switch state quantity is not changed, the first accelerator hard wire input voltage value and the second accelerator hard wire input voltage value are not located in the range of the preset voltage effective value respectively, and the existence of an accelerator message is detected, determining that the current target accelerator mode of the vehicle is the CAN bus mode.
For example, as shown in fig. 2, fig. 2 is a schematic block diagram of a mode identification process provided by the present application, and when a first accelerator hard-wire input voltage value U1, a second accelerator hard-wire input voltage value U2, and a preset voltage effective value interval [ Max, min ] are obtained, a dual mode plus low idle switching mode, a dual mode, a single mode, and a CAN bus mode may 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 current target accelerator mode of the vehicle is a dual-mode plus low-idle speed switch mode; or when the idle speed switch state quantity is not changed and U2 is within [ Max, min ], determining that the current target accelerator mode of the vehicle is a dual-mode; or when the idle speed switch state quantity is not changed, U2 is not in [ Max, min ] and U1 is in [ Max, min ], determining that the current target accelerator mode of the vehicle is a single mode; or when the throttle message value is detected to be greater than 0 under the conditions that the idle speed switch state quantity is not changed, U2 is not in [ Max, min ] and U1 is not in [ Max, min ], determining that the current target throttle mode of the vehicle is the CAN bus mode.
Further, after the identified target throttle mode is obtained, firstly, the identified target throttle mode is sent to a result judgment terminal, a mode judgment result from the result judgment terminal is received, and then the current vehicle is controlled to run according to the mode judgment result; or firstly obtaining the last historical target accelerator mode in the latch, then carrying out logic operation according to the identified target accelerator mode and the historical target accelerator mode, outputting a fault judgment result, and finally controlling the current vehicle to run according to the fault judgment result.
Specifically, the result judgment terminal comprises a driver instrument and a message detection device.
For example, as shown in fig. 3, fig. 3 is a schematic flow chart of determining the identified target accelerator mode according to the present application, and after the identified target accelerator mode is obtained, the target accelerator mode is sent to a driver meter for displaying, so that the driver can determine whether the result is accurate, and the driver can input the determination result after the determination is finished. Or sending the message related to the target accelerator mode to message detection equipment for generating a verification result after the detection equipment verifies the accuracy of the result.
Specifically, when a fault judgment result is output by performing logic operation according to an identified target throttle mode and a historical target throttle mode, first obtaining a first priority of the identified target throttle mode, then obtaining a second priority of the historical target throttle mode, then calling a fault logic service corresponding to the identified target throttle mode when the first priority is higher than the second priority, and finally performing logic operation according to the fault logic service corresponding to the identified target throttle mode to generate and output the fault judgment result. Or when the second priority is higher than the first priority, calling fault logic service corresponding to the historical target accelerator mode, finally performing logic calculation according to the fault logic service corresponding to the historical target accelerator mode, and generating and outputting a fault judgment result.
For example, as shown in fig. 4, fig. 4 is a schematic view of a fault determination process provided by the present application, after an identified target throttle mode is obtained, a last identified historical target throttle mode may be obtained, and then it is determined whether a priority of the currently identified throttle mode is higher than a priority of the historical target throttle mode, when the priority of the currently identified throttle mode is higher than the historical target throttle mode, the logic operation may be participated according to the currently identified throttle mode, otherwise, the logic operation may be participated according to the historical target throttle mode. When the logic operation is participated, the fault logic calculation strategy corresponding to the currently identified throttle mode or the historical target throttle mode can be called, and the fault judgment result can be calculated and output according to the corresponding strategy. The fault logic calculation strategy respectively comprises a double-mode and low-idle switch mode fault logic, a double-mode fault logic, a single-mode fault logic and a CAN mode fault logic.
In the embodiment of the application, the accelerator mode self-adaptive identification device firstly acquires the idle speed switch state quantity and the accelerator hard-wire input voltage parameter of the current vehicle in real time, then acquires the priority of each preset accelerator mode in a plurality of preset accelerator modes, determines a mode judgment order based on the priority order, and finally identifies the target accelerator mode of the current vehicle according to the mode judgment order, the idle speed switch state quantity and the accelerator hard-wire input voltage parameter. According to the method and the device, the idle speed switch state quantity and the accelerator hard wire input voltage parameters of the current vehicle are collected in real time, and the target accelerator mode to which the current vehicle belongs can be rapidly judged by combining the priority of each preset accelerator mode in a plurality of preset accelerator modes, so that the problem that different accelerator modes are required to be processed by an ECU supplier when the number of the current vehicle is ordered is solved, and the working efficiency is improved.
The following are embodiments of the apparatus of the present invention that may be used to perform embodiments of the method of the present invention.
