Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The power of the engine is controlled by the throttle. The opening of the throttle valve of the engine is controlled by controlling the opening of the accelerator pedal, and the air inflow is controlled, so that the rotating speed of the engine is controlled.
The existing accelerator pedal has the advantages that when the accelerator is small, the opening degree of a throttle valve is small, an air inlet channel is narrow, the air suction of an engine is difficult, the negative pressure of an air inlet manifold is high, and the air inlet amount is small; when the throttle valve is large, the opening of the throttle valve is large, the air inlet channel is wide, the engine can easily suck air, the negative pressure of the air inlet manifold is low, and the air inlet amount is large.
However, the accelerator pedal is affected by factors such as aging of the return spring, and the like, so that the problem that the opening degree of the accelerator cannot return to zero is caused, namely, the driver releases the accelerator pedal, but the opening degree of the accelerator pedal cannot return to zero. If the problems cannot be found in time, the oil consumption of the engine can be increased, and traffic accidents can be caused in severe cases, so that potential safety hazards are caused.
Therefore, in view of the above-mentioned problems, the present embodiment provides a method for detecting accelerator pedal homing performance, which determines accelerator pedal homing performance by comparing an accelerator pedal opening degree with a first preset opening degree threshold value when a failure that an accelerator pedal and a brake pedal are simultaneously depressed is detected in a target vehicle. And judging whether the accelerator pedal has the homing performance decline or the homing performance fault according to the total times of the homing performance decline and the total times of the homing performance fault, and further detecting the homing performance of the accelerator pedal in time, so that the potential safety hazard caused by the fact that the engine oil consumption is increased and traffic accidents are caused because the opening degree of the accelerator pedal cannot be found to be zero in time is avoided.
The present embodiment provides a method for detecting a homing performance of an accelerator pedal, which may be applied to a schematic architecture diagram of a system for detecting a homing performance of an accelerator pedal shown in fig. 1, as shown in fig. 1, the system provided in the present embodiment includes a terminal 101, and the terminal 101 includes: at least one of a receiving device, a processor, a display device, and a storage device. The receiving device can be used for receiving information such as an accelerator pedal signal, a brake pedal signal and an opening signal of an accelerator pedal; the storage device can store information such as a first preset opening threshold value, recorded times of reduction of homing performance of the accelerator pedal, recorded times of failure of homing performance of the accelerator pedal and the like; the display device can display process information such as whether the homing performance of the accelerator pedal is reduced or not and whether the homing performance fault occurs or not. If the processor of the terminal 101 detects that the target vehicle has a fault that an accelerator pedal and a brake pedal are simultaneously pressed down, detecting whether the opening degree of the accelerator pedal is smaller than a first preset opening degree threshold value; if the opening degree is smaller than the first preset opening degree threshold, the processor of the terminal 101 may increase the recorded number of times of the decline of the homing performance of the accelerator pedal, and determine whether the decline of the homing performance of the accelerator pedal occurs according to the increased total number of times of the decline of the homing performance; if the opening degree reaches the first preset opening degree threshold value, the processor of the terminal 101 may further increase the recorded number of times of the homing performance fault of the accelerator pedal, and determine whether the homing performance fault of the accelerator pedal occurs according to the increased total number of times of the homing performance fault.
The implementation manner of the terminal 101 is not particularly limited in this embodiment, and for example, the terminal 101 may be a mobile phone, a tablet, an Electronic Control Unit (ECU), or the like. Here, the accelerator pedal is also called an accelerator pedal, and mainly functions to control the opening of the throttle valve of the engine, so as to control the power output of the engine. The brake pedal, that is, the pedal of the service brake, is used for decelerating and stopping the vehicle, and the embodiment does not particularly limit the implementation manner thereof.
The following describes the technical solutions of the present application and how to solve the above technical problems with specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.
Fig. 2 is a schematic flowchart of a method for detecting the homing performance of an accelerator pedal according to an embodiment of the present disclosure, and an execution main body of the embodiment may be a processor in the terminal 101 according to the embodiment shown in fig. 1. As shown in fig. 2, the method may include:
s201: if the fault that the accelerator pedal and the brake pedal are simultaneously stepped on is detected, whether the opening degree of the accelerator pedal is smaller than a first preset opening degree threshold value or not is detected.
The target vehicle is a vehicle to be detected for the homing performance of an accelerator pedal.
For example, the above-mentioned detecting the target vehicle having the fault of simultaneously depressing the accelerator pedal and the brake pedal may be implemented by acquiring an accelerator pedal signal and a brake pedal signal, for example, if the accelerator pedal signal and the brake pedal signal are acquired simultaneously, the target vehicle having the fault of simultaneously depressing the accelerator pedal and the brake pedal is detected.
For example, the opening degree of the accelerator pedal may be detected by reading an opening degree signal of the accelerator pedal.
The first preset opening threshold may be set according to an actual application scenario, which is not limited in this embodiment.
S202: and if the opening degree is smaller than the first preset opening degree threshold value, increasing the recorded times of the decline of the homing performance of the accelerator pedal, and judging whether the decline of the homing performance of the accelerator pedal occurs or not according to the increased total times of the decline of the homing performance.
For example, the storage device may store the number N1 of times of decline of the homing performance of the accelerator pedal in one cycle, and in the same cycle, if the opening degree of the accelerator pedal is smaller than a first preset opening degree threshold, the number of times of decline of the homing performance is increased by one, and the total increased number of times of decline of the homing performance is (N1+ 1).
Optionally, the determining whether the accelerator pedal has the reduced homing performance according to the increased total number of times of the reduced homing performance may be implemented by, but not limited to:
judging whether the increased total number of the homing performance decline reaches a preset performance decline number threshold value or not;
and if the increased total number of the homing performance decline reaches a preset performance decline number threshold, judging that the homing performance decline of the accelerator pedal occurs.
The preset performance decline time threshold value can be preset according to an actual application scenario.
Illustratively, the total number of the increased homing performance decline is (N1+1), the preset performance decline threshold is N1, and if (N1+1) reaches N1, the accelerator pedal is determined to have the homing performance decline.
Whether the homing performance of the accelerator pedal is degraded or not can be accurately judged by comparing the increased total homing performance degradation times with a preset performance degradation time threshold.
Optionally, before the increasing the recorded number of times that the homing performance of the accelerator pedal declines, further comprising:
judging whether the maximum opening degree of the accelerator pedal when being stepped down again reaches a second preset opening degree threshold value or not;
and if the maximum opening degree reaches the second preset opening degree threshold value, executing the step of increasing the recorded times of the decline of the homing performance of the accelerator pedal.
The second preset opening threshold may be preset according to an actual application scenario, and may be, for example, a maximum opening that the accelerator pedal can reach in a normal state.
According to the comparison between the opening degree of the accelerator pedal and the first preset opening degree threshold value and the comparison between the maximum opening degree of the accelerator pedal and the second preset opening degree threshold value, whether the recorded times of the reduction of the homing performance of the accelerator pedal need to be increased or not can be accurately judged, and the accuracy of subsequently judging whether the reduction of the homing performance of the accelerator pedal occurs or not is further improved.
S203: and if the opening degree reaches the first preset opening degree threshold value, increasing the recorded times of the homing performance faults of the accelerator pedal, and judging whether the homing performance faults of the accelerator pedal occur or not according to the increased total times of the homing performance faults.
For example, the storage device may store the number N2 of homing performance failures of the accelerator pedal in one cycle, and if the accelerator pedal opening reaches the first preset opening threshold, the number of homing performance failures is increased by one in the same cycle, and the total number of the increased homing performance failures is (N2+ 1).
Optionally, the determining whether the accelerator pedal has the homing performance fault according to the increased total number of homing performance faults may be implemented by, but not limited to:
judging whether the increased total number of homing performance faults reaches a preset performance fault number threshold value or not;
and if the increased total number of homing performance faults reaches a preset performance fault number threshold value, judging that the accelerator pedal has the homing performance faults.
The preset performance fault frequency threshold value can be preset according to an actual application scene.
For example, the total number of the increased homing performance failures is (N2+1), the preset performance failure number threshold is N2, and if (N2+1) reaches N2, the accelerator pedal is judged to have the homing performance failure.
By comparing the increased total number of the homing performance faults with the preset performance fault number threshold value, whether the homing performance faults occur on the accelerator pedal can be accurately judged.
According to the method for detecting the homing performance of the accelerator pedal, the homing performance of the accelerator pedal is judged according to the comparison between the opening degree of the accelerator pedal and a first preset opening degree threshold value when the fault that the accelerator pedal and a brake pedal are simultaneously stepped down is detected in the target vehicle. And judging whether the accelerator pedal has the homing performance decline or the homing performance fault according to the total times of the homing performance decline and the total times of the homing performance fault, and further detecting the homing performance of the accelerator pedal in time, so that the potential safety hazard caused by the fact that the engine oil consumption is increased and traffic accidents are caused because the opening degree of the accelerator pedal cannot be found to be zero in time is avoided.
Fig. 3 is a schematic flowchart of another method for detecting the homing performance of the accelerator pedal according to an embodiment of the present disclosure, and an execution subject of the present embodiment may be a processor in the terminal 101 according to the embodiment shown in fig. 1.
As shown in fig. 3, the method includes:
s301: if the fault that the accelerator pedal and the brake pedal are simultaneously stepped on is detected, whether the opening degree of the accelerator pedal is smaller than a first preset opening degree threshold value or not is detected.
S302: and if the opening degree is smaller than the first preset opening degree threshold value, increasing the recorded times of the decline of the homing performance of the accelerator pedal, and judging whether the decline of the homing performance of the accelerator pedal occurs or not according to the increased total times of the decline of the homing performance.
S301-S302 are the same as the implementation of S201-S202 described above, and are not described here again.
S303: and acquiring a voltage value corresponding to the opening degree of the accelerator pedal.
Illustratively, a voltage signal corresponding to the opening degree of the accelerator pedal is read through a receiving device, so that a voltage value corresponding to the opening degree of the accelerator pedal is obtained; the acquired voltage value corresponding to the opening degree of the accelerator pedal may be stored in the storage device.
S304: and if the homing performance of the accelerator pedal is reduced, adjusting a corresponding curve of the voltage and the opening degree of the accelerator pedal of the target vehicle.
Optionally, the adjusting the corresponding curve of the accelerator pedal voltage and the opening degree of the target vehicle may be implemented by, but not limited to:
and adjusting a corresponding curve of the accelerator pedal voltage and the opening of the target vehicle according to the voltage value corresponding to the opening of the accelerator pedal.
For example, when the homing performance of the accelerator pedal declines, the corresponding curve of the voltage and the opening degree of the accelerator pedal does not conform to the corresponding relationship of the actual voltage and the opening degree of the accelerator pedal, and the voltage corresponding to the zero opening degree in the corresponding curve of the voltage and the opening degree of the accelerator pedal is shifted upwards to the average value of the voltage corresponding to the minimum opening degree when the homing performance of the accelerator pedal declines by adjusting the corresponding curve of the voltage and the opening degree of the accelerator pedal of the target vehicle, so that the adjusted corresponding curve of the voltage and the opening degree of the accelerator pedal conforms to the corresponding relationship of the actual voltage and the opening degree of the accelerator pedal. For example, in a period, the accelerator pedal has n times of reduction of homing performance, and when the accelerator pedal has the first reduction of homing performance, the voltage of the minimum opening degree is V1; when the homing performance of the accelerator pedal declines for the second time, the voltage of the minimum opening degree is V2; when the returning performance of the accelerator pedal declines for the nth time, the voltage of the minimum opening is Vn, the average voltage value V of the minimum opening when the returning performance of the accelerator pedal declines in the period is (V1+ V2+ … … + Vn)/n, and the voltage corresponding to the zero opening in the corresponding curve of the voltage and the opening of the accelerator pedal is shifted upwards to V.
The corresponding curve of the voltage and the opening degree of the accelerator pedal of the target vehicle is adjusted according to the voltage value corresponding to the opening degree of the accelerator pedal, so that the adjusted corresponding curve of the voltage and the opening degree of the accelerator pedal can be consistent with the corresponding relation of the actual voltage and the opening degree of the accelerator pedal, and the problem of the reduction of the homing performance of the accelerator pedal is compensated by automatically modifying the corresponding curve of the voltage and the opening degree of the accelerator pedal.
S305: and repairing the reduction of the homing performance of the accelerator pedal according to the adjusted curve.
According to the method for detecting the homing performance of the accelerator pedal, the homing performance of the accelerator pedal is judged according to the comparison between the opening degree of the accelerator pedal and a first preset opening degree threshold value when the fault that the accelerator pedal and a brake pedal are simultaneously stepped down is detected in the target vehicle. And whether the homing performance of the accelerator pedal is declined or not is judged according to the total times of the homing performance decline, so that the homing performance of the accelerator pedal can be detected in time, and the potential safety hazard caused by traffic accidents due to the fact that the oil consumption of an engine is increased because the opening degree of the accelerator pedal cannot be found to be zero in time is avoided. The voltage value corresponding to the opening degree of the accelerator pedal is obtained, the corresponding curve of the voltage and the opening degree of the accelerator pedal of the target vehicle is adjusted, the corresponding curve of the voltage and the opening degree of the adjusted accelerator pedal can be matched with the corresponding relation of the actual voltage and the opening degree of the accelerator pedal, and the problem of the reduction of the homing performance of the accelerator pedal is compensated by automatically modifying the corresponding curve of the voltage and the opening degree of the accelerator pedal.

As shown in fig. 4, the method includes:
s401: if the fault that the accelerator pedal and the brake pedal are simultaneously stepped on is detected, whether the opening degree of the accelerator pedal is smaller than a first preset opening degree threshold value or not is detected.
S401 is the same as the implementation of S201 described above, and is not described here again.
S402: and if the opening degree reaches the first preset opening degree threshold value, increasing the recorded times of the homing performance faults of the accelerator pedal, and judging whether the homing performance faults of the accelerator pedal occur or not according to the increased total times of the homing performance faults.
S402 is the same as the implementation of S203 described above, and is not described here again.
S403: and if the accelerator pedal has the homing performance fault, sending prompt information to preset personnel, wherein the prompt information is used for informing the preset personnel that the accelerator pedal has the homing performance fault.
Here, the preset personnel refers to personnel capable of receiving the prompt information, and the preset personnel may be preset according to an application scenario, which is not limited in this embodiment.
The prompting information is sent to the preset personnel to inform the preset personnel that the homing performance fault occurs on the accelerator pedal of the target engine, so that the preset personnel can overhaul, and the problems of increased oil consumption and safety of the engine caused by the homing performance fault of the accelerator pedal are avoided.
