Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

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 an adaptive learning method for a zero point position of an accelerator pedal, including:
here, the current operating state of the vehicle is acquired in order to perform step 102, that is, in order to facilitate the determination of whether the vehicle currently satisfies the preset condition for learning based on these states, so the parameters of the acquired operating state include at least parameters for determining the preset condition.
in an embodiment of the present invention, the current operating state of the vehicle indicates that the vehicle currently satisfies a preset condition for performing adaptive learning of the zero point position of the accelerator pedal, including: the vehicle is currently in a preset gear; the current operating state of the accelerator pedal of the vehicle indicates that the vehicle is not currently in a hill-hold fault condition.
The vehicle is provided with four gears of START, ON, ACC and L OCK in the related art, L OCK is a gear for locking a steering wheel, ACC is a gear for turning ON the power supply of electric equipment of the automobile part but not driving, ON is a gear for turning ON all electric elements in the vehicle and is at the position during the driving of the vehicle, START is used for igniting a starting position, the preset gear is preferably ON because a driver needs to operate an accelerator pedal during the driving of the vehicle, meanwhile, when the vehicle is in a hill-climbing fault state, the vehicle is often in a power-limiting mode, namely, the output power is still low even if the accelerator pedal is large in opening degree, and therefore the vehicle is not suitable for self-adaptive learning of the zero position of the accelerator pedal when the hill-climbing fault occurs.
And 103, if the real-time opening degrees are smaller than the opening degree of the currently stored zero position of the accelerator pedal and larger than the preset opening degree within the preset time period, setting the zero opening degree of the accelerator pedal as the real-time opening degree, and updating the stored zero position of the accelerator pedal to the real-time opening degree.
Here, due to the influence of factors such as electromagnetic interference, data abnormality may occur in a moment or in a short time, and if learning is performed based on the abnormal opening degree of the accelerator pedal, for example, the data abnormality increases, the accelerator pedal depression opening degree may be large after learning based on the data, but the calculated opening degree change is small, so by setting a preset time period, learning is performed when the real-time opening degree continues for the preset time period and the above condition is satisfied, and the situation that the abnormal zero point position of the accelerator pedal is learned due to the instantaneous or short-time data abnormality caused by electromagnetic interference can be effectively avoided. It may be preferable for the preset time period to be 15ms to 30 ms.
The zero-point opening of the accelerator pedal is set to be the real-time opening, and the stored zero-point position of the accelerator pedal is updated to be the real-time opening, where the real-time opening of the preset time period is compared, so that the finally set real-time opening and the stored real-time opening may be the real-time opening acquired for the first time in the preset time period, the real-time opening acquired for the last time in the preset time period, the real-time opening with the smallest opening value in the preset time period, or an average value of the real-time openings acquired in the preset time period.
Here, in order to avoid learning an abnormal zero position and causing an abnormal accelerator pedal opening output, it is necessary to deal with the lower limit of the learned zero position as well, and in consideration of the voltage deviation due to aging of the accelerator pedal sensor, the real-time opening also needs to be larger than a preset opening, which may be an accelerator pedal opening corresponding to the lower limit of the output voltage of the accelerator pedal sensor of the vehicle. For example, the opening degree converted from the lower limit of the output voltage of the accelerator pedal sensor is multiplied by an accelerator opening degree amplification factor K as the lower limit value of the zero point position.
In step 103, the real-time opening degree needs to be compared with the currently stored opening degree of the accelerator pedal zero-point position, and for this, the adaptive learning method for the accelerator pedal zero-point position may further include:
and when the vehicle enters a whole vehicle power-on state, updating the stored opening degree of the zero position of the accelerator pedal to a preset initial value, wherein the opening degree output of the accelerator pedal is less than or equal to 0 when the accelerator pedal is at any position under the preset initial value.
Here, each time the whole vehicle is powered on, during the initialization process of the VCU, the stored opening degree of the zero point position of the accelerator pedal is updated to a preset initial value, that is, corresponding learning is performed during the driving process, so as to adapt to driving habits and the like of different drivers. The preset initial value may be a larger value, which is greater than 100%, for example, 150%, to ensure that when the accelerator pedal is fully depressed, ON is powered ON, the output of the accelerator pedal opening is 0%, and the calibration may be performed with reference to the following formula:
initial value ≥ VMax_APS-VMin_APS)/5)·100％·K
In the formula: vMax_APSUpper limit of output voltage of accelerator pedal sensor, VMin_APSAnd K is the lower limit of the output voltage of the accelerator pedal sensor, and is the amplification factor of the opening degree of the accelerator pedal.
Referring to fig. 3 and 4, in the related art, 2-way accelerator pedal sensors are often used for acquiring the opening degree of an accelerator pedal, for example, data of two-way sensors shown in fig. 3, voltage signals of the 2-way sensors are processed according to respective preset weights, as shown in fig. 3, the voltages of a first accelerator pedal sensor and a second accelerator pedal sensor are in a 2-fold relationship, and the corresponding output opening degree ranges from 13% to 93% with reference to a 5V reference voltage. A map of the correspondence relationship of the voltage to the opening degree shown in fig. 4 is obtained, where the upper limit of the output voltage and the lower limit of the output voltage, and the lower limit of the output voltage of the accelerator pedal sensor mentioned hereinafter, refer to the processed voltage.
For step 103, the step of setting the zero-point opening of the accelerator pedal to the real-time opening may include:
and attenuating the zero opening of the accelerator pedal to the real-time opening through a first-order filtering algorithm. The zero-point opening degree of the accelerator pedal is attenuated to the real-time opening degree through the first-order filtering algorithm, so that the influence of sudden change on the operation feeling of a driver can be avoided.
Preferably, the adaptive learning method for the zero point position of the accelerator pedal further includes:
and if the current working state of the vehicle indicates that the vehicle does not meet the preset condition for carrying out self-adaptive learning on the zero position of the accelerator pedal currently, setting the zero opening of the accelerator pedal as a preset initial value.
Here, the zero-point opening degree of the accelerator pedal is set to a preset initial value under the condition that the learned preset condition is not satisfied, so that driving safety due to a fault is avoided.

the first acquisition module 201 is used for acquiring the current working state of the vehicle;
