The terms "first," "second," "third," "fourth," and the like in the description and in the claims of the present application and in the drawings described above, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that the embodiments described herein may be practiced otherwise than as specifically illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus. 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 only a part of the embodiments of the present application, and not all of the embodiments.
Referring to fig. 1, a schematic flow chart of a vehicle acceleration control method provided in an embodiment of the present application may specifically include:
s110, acquiring an acceleration average value and an acceleration standard deviation of the vehicle in a sampling interval;
specifically, during the acceleration and deceleration of the vehicle, the driving habits of different drivers are different, and the accelerating and decelerating effects of the vehicle are different. In addition, the driving habits of the same driver in different speed intervals are different, some driver habits and low-speed areas are accelerated rapidly to seek higher speed, the driving behavior is not carried out any more when the speed is increased to a certain degree, and the acceleration of the vehicle is not linear change behavior. Thus, the driver needs to adapt to the response relationship between the opening degrees of the brake pedal and the accelerator pedal of the vehicle and the acceleration and deceleration, usually, the vehicle is already assigned with the corresponding relationship between the brake pedal and the accelerator pedal and the engine torque at the time of factory shipment, and the user can only adapt to the acceleration or deceleration characteristics of the vehicle. The vehicles with higher rank can preset several different modes, but no vehicle can make a vehicle which completely accords with the driving habits of the driver according to different drivers.
According to the scheme provided by the embodiment, through setting a reasonable sampling interval, the average value and the standard deviation of the acceleration of the user in an acceleration interval or a deceleration interval are firstly collected. The acceleration average value is obtained by dividing a sampling interval into a plurality of time periods according to a preset sampling rule in the sampling interval, calculating the acceleration of the vehicle in each time period, and averaging the accelerations in all the time periods to obtain the acceleration average value, wherein the standard deviation is calculated according to the acceleration in each time period. It will be appreciated that the average value of the acceleration may be indicative of the severity of acceleration or deceleration of the driver over the sampling interval, and the standard deviation may be indicative of whether the acceleration of the driver over the sampling interval is linear, if the standard deviation is large, the acceleration is highly variable during acceleration or deceleration, if the standard deviation is small, the acceleration is approximately linear during acceleration or deceleration, and the average value of the acceleration and the standard deviation are combined to better characterize the acceleration and deceleration characteristics of the driver.
S120, acquiring an average value of preset average values of the accelerations as a first correction value;
specifically, the single sampling result may have randomness, and an average value of the acceleration is calculated as the first correction value for a preset number of sampling results.
It will be appreciated that this acceleration also includes acceleration and deceleration, and that the preset number may be set by the user or developer, and that the preset number may be 5, 10 or other numbers.
S130, acquiring the average value of the preset acceleration standard deviations as a second correction value;
specifically, the single sampling result may have randomness, and an average value of the standard deviation of the acceleration is calculated as the second correction value for the preset sampling result.
It will be appreciated that this acceleration also includes acceleration and deceleration, and that the preset number may be set by the user or developer, and that the preset number may be 5, 10 or other numbers. The preset number of steps is the same as the number of steps S120, and the steps S120 and S130 are not in sequence.
And S140, acquiring an acceleration correction coefficient based on the first correction value, the second correction value, a first preset value and a second preset value, wherein the first preset value is acquired based on a historical acceleration average value, and the second preset value is acquired based on a historical acceleration standard deviation.
Specifically, the first preset value and the second preset value are obtained based on historical data, and the historical data may be data that is installed in the vehicle before the vehicle leaves a factory, or may be data counted based on big data. According to the first correction value and the first preset value, a correction coefficient of the average acceleration can be obtained, a correction coefficient of the acceleration standard deviation can be obtained through the second correction value and the second preset value, and a final acceleration correction coefficient can be obtained through the correction coefficients of the acceleration and the standard deviation. It is understood that the correction coefficients include an acceleration correction coefficient and a deceleration correction coefficient.
And S150, correcting the pedal opening according to the correction coefficient, wherein the pedal opening comprises an accelerator pedal opening and a brake pedal opening.
Specifically, the opening degree of the accelerator pedal is corrected according to the acceleration correction coefficient, and the opening degree of the brake pedal is corrected according to the deceleration correction coefficient, so that the vehicle can provide a dynamic response more conforming to the driving behavior of the user for the user, and the delay between the pedal and the acceleration during acceleration and deceleration is reduced.
In summary, according to the embodiment of the application, the acceleration average value and the acceleration standard deviation of the acceleration and deceleration behaviors are counted by acquiring the preset acceleration and deceleration behaviors in the sampling interval, the correction coefficients of the accelerator pedal and the brake pedal are acquired based on the acquired acceleration average value and standard deviation and the average value and standard deviation in the historical data, and the opening of the accelerator pedal and the opening of the brake pedal are corrected according to the correction coefficients, so that the vehicle can provide dynamic response which is more in line with the driving behaviors of the user for the user, delay between the pedal and the acceleration during acceleration and deceleration is reduced, and the driving experience of the driver is improved.
In some examples, the obtaining the acceleration correction coefficient based on the first correction value, the second correction value, the first preset value, and the second preset value includes:
acquiring an acceleration correction coefficient based on the first correction value, the second correction value, the first preset value, the second preset value, the first weight and the second weight;
wherein the first weight is set based on an acceleration average value, and the second weight is set based on an acceleration standard deviation.
Specifically, the correction coefficient may be calculated according to formula (1)
Figure BDA0003323274160000071
In the formula, mukAlpha is a first weight for the correction coefficient,
Figure BDA0003323274160000072
is a first correction value for the first image data,
Figure BDA0003323274160000073
is a first preset value, beta is a second weight, lambdakIs the second correction value, δkIs the second preset value.
The influence of the acceleration average value and the acceleration standard deviation on the correction coefficient is controlled by setting the first weight value and the second weight value, the average value can better represent the quick response of acceleration, the standard deviation can better represent the linear degree of acceleration, and a driver or a developer can work out the correction coefficient which accords with users with different driving habits by reasonably setting the first weight value and the second weight value, so that the vehicle acceleration control method is optimized.
In summary, a more detailed speed control strategy can be made for the average value and the standard value of the acceleration by setting the first weight and the second weight, so as to meet the driving habits of different drivers.
In some examples, the predetermined number of the acceleration averages and the predetermined number of the acceleration standard deviations are iteratively updated.
Specifically, the preset number can be 5, and the number of the preset number is sequentially numbered from first to last according to the acquisition sequence, namely, the number 1 data, the number 2 data, the number 3 data, the number 4 data and the number 5 data, and the average value is obtained through the number 1 to 5 data, so that the correction coefficient is determined. In order to ensure that the vehicle can be dynamically adjusted according to the driving behavior of the user, when the vehicle collects the data No. 6, the data No. 1 is deleted, and the data No. 2 to 6 are used for calculating the average value so as to determine the correction coefficient. When the next valid data is collected, the above operation is repeated to ensure that the correction coefficient is changed along with the change of the habit of the driver. It should be noted that the above 5 are only used for the applicant to explain the method of the present embodiment, and the specific numerical values are not limited herein.
In conclusion, the acceleration average value and the acceleration standard deviation are updated iteratively, so that the correction coefficient can be changed along with the change of the driving habits of the driver, and an acceleration control scheme which is more in line with the driving habits of the driver is specified.
In some examples, the above-described operation of iterative updating is turned off based on a user instruction.
Specifically, the user may close the iterative update operation through a corresponding button or a corresponding human-computer interaction interface. The acceleration control strategy of the vehicle is changed according to the driving habits of other people when the vehicle is lent to other people for short time use.
In some examples, the sampling interval includes an acceleration sampling interval that is set according to a vehicle speed and an accelerator pedal opening.
Specifically, when the vehicle speed is higher than a first threshold value and lower than a second threshold value and the opening degree of an accelerator pedal is larger than a first preset opening degree, the vehicle is in an acceleration sampling interval at the moment, and the acceleration behavior is sampled. The sampling result can be prevented from being influenced by the wrong operation of the accelerator pedal by a driver by integrating the vehicle speed and the opening degree of the accelerator pedal.
In some examples, the sampling interval includes a deceleration-acceleration sampling interval, and the deceleration sampling interval is set according to a vehicle speed and a brake pedal opening.
Specifically, when the vehicle speed is higher than a third threshold value and lower than a fourth threshold value and the brake pedal opening degree is larger than a second preset opening degree, the vehicle is in a deceleration sampling interval, and the deceleration behavior is sampled. The vehicle speed and the brake pedal opening degree are integrated, so that the influence of the wrong operation of a driver on the brake pedal on a sampling result can be avoided.
In some examples, the correction factor is updated based on a user instruction.
Specifically, the user may set 3, 5, or 8 or other arbitrary values, and the user may set different acceleration strategies for other scenes, such as urban areas, high speed, or rural areas, by setting different correction coefficients. When the vehicle runs in different scenes, the acceleration strategy more suitable for the current scene is selected, and therefore better driving experience is obtained.
