Thus, the appearances of the phrases "in one embodiment" or "in an embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.
In the embodiments provided herein, it should be understood that "B corresponding to a" means that B is associated with a from which B can be determined. It should also be understood that determining B from a does not mean determining B from a alone, but may be determined from a and/or other information.
Referring to fig. 1, an embodiment of the present invention provides a control method of an accelerator pedal, including:
102, when the accelerator pedal fault is not detected, determining a first calculation voltage for calculating the pedal opening according to the detected first detection voltage of the first accelerator pedal position sensor; and determining a second calculation voltage for calculating the pedal opening degree based on the detected second detection voltage of the second accelerator pedal position sensor;
if the first detection voltage is out of a first preset range of the first normal working voltage and lasts for a first preset time, determining that the first calculation voltage is a first preset voltage value;
if the second detection voltage is out of a second preset range of a second normal working voltage and lasts for a first preset time, determining that the second calculation voltage is a second preset voltage value;
here, the first normal operating voltage and the first predetermined range are both determined based on the characteristic curve of the first accelerator pedal position sensor, the first predetermined range is a range defined by the characteristic curve, i.e., a lower limit value and an upper limit value of the characteristic curve, the range of the first normal operating voltage is greater than the first predetermined range, for example, if the characteristic curve of the first accelerator pedal position sensor is composed of voltage values a to b, the first predetermined range may be set to [ a, b ], and the first normal operating voltage is [ a-n, b + m ], where n and m may be the same, for example, both are 1. For example, if the characteristic curve is in the range of 2-3V, the first predetermined range is set to [2, 3], and the first normal operating voltage range may be [1, 4 ]. Here, the range of the first normal operating voltage is greater than the first preset range, and the first preset duration is set, so that the situation that the instantaneous voltage is more frequently exceeded and the influence of the fault on the driver is continuously reported in the driving process can be prevented. The second normal operating voltage and the second preset range are both determined according to the characteristic curve of the second accelerator pedal position sensor, and the range of the second normal operating voltage is larger than the second preset range. It can be understood that the setting of the second normal operating voltage and the second preset range and the setting of the first normal operating voltage and the first preset range may be referred to each other, and details thereof are not repeated.
Here, when the first detected voltage is within the first normal operating voltage range, being outside the first preset range, the first calculated voltage is set to a first preset voltage value, which may be a lower limit value between voltage value ranges of the characteristic curve of the first accelerator pedal position sensor. Similarly, the second preset voltage value may be a lower limit value between voltage value ranges of the characteristic curve of the first human accelerator pedal position sensor. The lower limit value is used for calculating the opening degree of an accelerator pedal, so that driving safety is guaranteed.
And 103, determining the output opening degree of the accelerator pedal according to the first calculated voltage and the second calculated voltage.
The embodiment of the invention is provided with the first normal working voltage and the second normal working voltage, and when the checking voltage of the accelerator pedal position sensor is within the normal working voltage but outside the preset range set by the normal working voltage, the preset voltage is determined as the calculation voltage for calculating the pedal opening, so that the driving safety is ensured.
Of course, the control method of the accelerator pedal may further include:
if the first detection voltage is within the first preset range, determining the first calculation voltage as the first detection voltage;
and if the second detection voltage is within the second preset range, determining the second calculation voltage as the second detection voltage.
When the detected voltage is within the preset range and indicates that the current voltage is normal, the detected voltage is adopted to calculate the pedal output opening.
Preferably, the control method of the accelerator pedal may further include:
and if the first detection voltage is positioned outside the first normal working voltage and lasts for a second preset time length, or the second detection voltage is positioned outside the second normal working voltage and lasts for the second preset time length, outputting an accelerator pedal fault signal.
If the detection voltage is out of the corresponding normal working voltage and lasts for a second preset time, the current accelerator pedal is in fault, and an accelerator pedal fault signal is output. It should be noted that, because the voltage value of the first accelerator pedal position sensor and the voltage value of the second accelerator pedal position sensor are approximately in a two-fold relationship, two-way collection is also set to prevent errors, so that when any one of the detected voltages is abnormal (is located outside the corresponding normal working voltage), the other detected voltage is also unreliable, and therefore when any one of the first detected voltage or the second detected voltage is located outside the corresponding normal working voltage, an accelerator pedal fault signal is output, and driving safety is guaranteed.
Preferably, the control method of the accelerator pedal may further include:
and if the absolute value of the difference value between the accelerator pedal opening value represented by the first detection voltage and the accelerator pedal opening value represented by the second detection voltage is greater than a preset value and lasts for a third preset time period, outputting an accelerator pedal fault signal.
Here, the first detection voltage should be approximately twice the second detection voltage due to the accelerator pedal characteristic, and when the two-way voltage value does not conform to the approximately twice relationship and continues for a third preset time duration, it is determined that the accelerator pedal has a verification failure. Here, when the absolute value of the difference between the opening values of the two is larger than a preset value (the preset value may be about 10), it may be judged that the two do not satisfy the approximate double relation.
It is understood that the preset time periods can be set according to actual needs, and can be the same or different. The setting of the preset time can avoid frequent fault reporting in the driving process caused by instantaneous faults.
Because of the accelerator pedal voltage characteristic, when the accelerator pedal is not depressed, the accelerator pedal voltage value is also not 0, and the calculated original opening degree is also not 0, so that the zero point position learning of the accelerator pedal opening degree is performed. Therefore, in an embodiment of the present invention, in step 103, the step of determining the output opening degree of the accelerator pedal according to the first calculated voltage and the second calculated voltage may include:
calculating to obtain the real-time normalized opening degree of the accelerator pedal according to the first calculated voltage and the second calculated voltage;
here, the normalized opening degree may be calculated according to the formula, where K is (opening degree · c indicated by the first calculation voltage + opening degree · d indicated by the second calculation voltage) · e, where c may be equal to d, may be 0.5, and e may be 1.6.
If the real-time normalized opening degree is smaller than the currently stored zero opening degree, larger than the preset opening degree and lasts for a fourth preset time, setting the zero opening degree of the accelerator pedal as the real-time normalized opening degree, and updating the stored zero opening degree of the accelerator pedal to the real-time normalized opening degree;
here, the initially set zero-point opening degree at which the accelerator pedal is at any position and the output opening degree is 0 may be set to be greater than 100. The minimum position can be continuously learned through the comparison between the real-time normalized opening degree and the stored zero opening degree, and certainly, the embodiment of the invention also provides a preset opening degree to ensure that the abnormal zero position cannot be learned. The fourth preset time length can be set to prevent the zero learning value from jumping frequently.
And determining the output opening of the accelerator pedal according to the real-time normalized opening and the currently stored zero opening of the accelerator pedal.
Here, the output opening is an opening normalized in real time — zero opening.
Preferably, the control method of the accelerator pedal may further include:
and if the real-time normalized opening degree is smaller than the preset opening degree and lasts for a fourth preset time, setting the zero opening degree of the accelerator pedal as the preset opening degree, and updating the stored zero opening degree of the accelerator pedal as the preset opening degree.
Here, if the real-time normalized opening degree is smaller than the set preset opening degree, the zero-point opening degree is set to the preset opening degree. Here, the real-time normalization opening degree smaller than the preset opening degree is not set, so that the abnormal low zero point position is not output.
