Description

Technical Field

[0001] This application relates to the field of intelligent driving assistance technology, and particularly to a method, device, computer device, and storage medium for adjusting the driving intensity index. Background Art

[0002] With the rapid development of intelligent driving assistance technology, intelligent recognition of driving patterns has emerged. Its working principle is that the vehicle control unit adjusts the power response parameters according to the Driver Sportyness Index (DSI) so that the power output of the vehicle matches the driving intensity index.

[0003] Among them, the driving intensity index is an indicator that quantifies the intensity of a driver's driving of a vehicle. Related technologies usually evaluate the driver's driving intensity index based on vehicle behavior data such as the depth of the accelerator and brake pedals, the accelerator change rate, vehicle speed, and acceleration.

[0004] However, this method has the following defects: when the value of the vehicle behavior data continuously decreases, the value of the driving intensity index also continuously decreases, and the power system continuously lowers the power response parameters to suppress the power output. When the value of the vehicle behavior data continuously increases, the value of the driving intensity index also continuously increases, and the power system continuously raises the power response parameters to increase the power output. Then, when the driving intensity index decreases below a certain value or increases above a certain value, if the driver's actual power demand suddenly increases or decreases, and the power system cannot adjust the power response parameters in time, it will lead to difficulty in matching the actual power output with the actual power demand, which requires the driver to specifically adjust the operation, resulting in a reduction in the driving operation comfort of the driver.

[0038] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0039] The driving intensity index is an index that quantifies the intensity of a driver's vehicle driving. With the rapid development of intelligent driving assistance technology, the current power system can automatically adjust power response parameters according to the driving intensity index, so that the power output of the vehicle matches the driving intensity index. Currently, the related technology always calculates the driving intensity index based on vehicle behavior characteristics such as the depth of the accelerator and brake pedals and the vehicle speed. This method has the following defects: when the values of the vehicle behavior characteristics continuously decrease, the value of the driving intensity index will also continuously decrease, and the power system will suppress the power output of the vehicle by continuously restricting the fuel injection volume and reducing the gearshift speed of the transmission. When the driving intensity index drops below a certain value, if the driver's power demand suddenly increases, it is difficult for the system to adjust the power response parameters in a timely manner, resulting in a lag in power output behind the driver's actual demand; conversely, when the values of the vehicle behavior characteristics continuously increase, the value of the driving intensity index will also continuously increase, and the power system will increase the power output by increasing the fuel injection volume, increasing the engine torque output slope, and advancing the ignition angle. When the driving intensity index increases above a certain value, the driver can achieve a large power output by gently stepping on the accelerator pedal. If the driver's power demand suddenly decreases, it is difficult for the system to adjust the power response parameters in a timely manner, resulting in a power output higher than the driver's actual power demand. It can be seen that too low or too high a driving intensity index will cause the subsequent power response to be difficult to match the driver's actual power demand, and the driver needs to actively adjust the driving operation. Especially for drivers with insufficient driving experience, it may take some time to find the adjustment range. Therefore, the related technology ignores the impact of the subsequent power response on the driver's driving operation comfort, reducing the driver's driving operation comfort.

[0040] To this end, the present application proposes a method, device, computer device and storage medium for adjusting the driving intensity index. After detecting the update of the value of the current driving intensity index and at an interval of a first preset duration, the current driving operation comfort index of the driver is calculated. If the current driving operation comfort index is within the preset comfort index range, the value of the current driving intensity index is maintained. If the current driving operation comfort index is not within the comfort index range, the value of the current driving intensity index is feedback-adjusted according to the current driving operation comfort index so that the current driving operation comfort index is maintained within the comfort index range. It can be seen that the present application can always maintain the value of the driving intensity index within a certain range, so that the driving operation comfort index of the driver is always maintained within the comfort index range, improving the phenomenon in the related art that when the driving intensity index is too low and the driver's power demand increases, or when the driving intensity index is too high and the driver's power demand decreases, it is difficult for the actual power output to match the actual power demand, and the driver needs to appropriately adjust the driving operation. Therefore, compared with the related art, the present application takes into account the influence of the subsequent vehicle power response on the driving operation comfort of the driver and improves the driving operation comfort of the driver.

[0041] Next, the present application will be introduced in detail through the following embodiments.

[0042] In one embodiment, as Figure 1 shown, a method for adjusting the driving intensity index is provided. Taking the application of this method to the vehicle control unit as an example, the method includes the following steps:

[0043] Step 202: After detecting the update of the value of the current driving intensity index and at an interval of a first preset duration, calculate the current driving operation comfort index of the driver.

[0044] Generally, before performing step 202, the driving intensity index of the driver in the past period of time can be calculated according to the vehicle behavior characteristics in the past period of time, and the value of the current driving intensity index in the current operation cycle is updated according to its value.

[0045] The driving intensity index is an index that quantifies the intensity of the driver's driving of the vehicle. It can evaluate the driving intensity of the driver according to vehicle behavior characteristics such as the depth of the accelerator and brake pedals, the accelerator change rate, the vehicle speed, and the acceleration.

[0046] Exemplary illustration: Vehicle behavior characteristics are collected once every unit cycle, including average vehicle speed, maximum vehicle speed, maximum acceleration, maximum jerk, maximum steering wheel angle, and maximum yaw rate. This is repeated multiple times to obtain vehicle behavior characteristics within multiple consecutive unit cycles. According to the average vehicle speed and maximum vehicle speed within each unit cycle, the corresponding driving speed conditions are determined according to a preset first comparison rule, including congestion condition, low-speed driving condition, medium-speed driving condition, and high-speed driving condition. According to the maximum acceleration, maximum jerk, maximum steering wheel angle, and maximum yaw rate within each unit cycle, the corresponding driving habits are determined according to a preset second comparison rule, including conservative driving, conventional driving, and aggressive driving. Taking the whole composed of multiple unit cycles as the recognition cycle, according to the time proportion and corresponding preset weight proportion of each driving speed condition in the entire recognition cycle, the target proportion of each driving speed condition in the entire recognition cycle is calculated. All driving habits involved in each driving speed condition are counted, and according to the preset scores corresponding to each driving habit, the average driving habit score corresponding to each driving speed condition is calculated. According to the target proportions and average driving habit scores corresponding to all types of driving speed conditions, the driving intensity index of the driver in the entire recognition cycle is calculated.

[0047] The driving operation comfort index is an index that quantifies the comfort feeling of the driver during the operation of each functional component. The driving operation comfort index is related to the driver's driving operation. Therefore, its value can be calculated and determined according to the driver's driving operation characteristics. Especially for the driving operations corresponding to relatively large or small power demands, the driver's comfort feeling during driving operations is more obvious. Therefore, the driving operation comfort of the driver can be calculated according to the driving operation characteristics when the driver's power demand is greater than a certain value or less than a certain value.

[0048] After calculating the current driving intensity index based on the vehicle behavior characteristics, the vehicle control unit will send it to the powertrain. After receiving the current driving intensity index, the powertrain will adjust its own power response parameters, including but not limited to adjusting fuel injection volume, transmission shift speed, engine torque output slope, and ignition angle, etc., to adapt the power output of the powertrain to the power demand corresponding to the driver's driving intensity. When the powertrain adjusts the power response parameters, the comfort feeling that the driver experiences when operating each functional component of the vehicle may change compared to before the adjustment. Therefore, after the value of the current driving intensity index is updated, it is necessary to wait for a first preset duration, such as 10 hours, before calculating the driver's current driving operation comfort index to be able to reflect the comfort feeling of the driver when operating each functional component after the value of the current driving intensity index is updated, that is, after the power response parameters are updated.

[0049] Step 204, if the current driving operation comfort index is within the preset comfort index range, then maintain the value of the current driving intensity index;

[0050] Step 206, if the current driving operation comfort index is not within the comfort index range, then perform feedback adjustment on the value of the current driving intensity index according to the current driving operation comfort index, so that the current driving operation comfort index is maintained within the comfort index range.

[0051] Since the driver's driving intensity index affects the power response parameters of the power system, and the power response parameters in turn affect the driver's driving operation comfort index, that is, the driver's driving intensity index affects his own driving operation comfort index, and too low or too high driving intensity index will reduce the driver's driving operation comfort. Therefore, in order to maintain the current driving intensity index within a certain range, this application sets a comfort index range. This comfort index range can be determined through actual vehicle testing. Since it is not appropriate for the driver to have too high or too low comfort when operating each functional component, and it is impossible to accurately estimate the power output, the comfort index range can be set as a central range, for example, [30, 70].

[0052] When the current driving intensity index is too low or too high, the corresponding driving operation comfort index will be lower or higher than the comfort index range. The comparison result between the current driving operation comfort index and the comfort index range is fed back to the numerical adjustment of the current driving intensity index: if the current driving operation comfort index is within the comfort index range, no operation is performed and the value of the current driving intensity index is maintained; otherwise, the current driving intensity index is adjusted according to the current driving operation comfort index. In order to make the current driving operation comfort index within the comfort index range after adjustment, the current driving intensity index can be adjusted specifically according to the difference between the current driving operation comfort index and the comfort index range. In this way, the value of the current driving intensity index is controlled within a certain range, so that the driver's driving operation comfort index is always maintained within the comfort index range, improving the problem of low driving operation comfort when the driving intensity index is too low or too high, and enhancing the driver's driving operation comfort.

[0053] Among them, if the current driving operation comfort index is lower than the comfort index range, it means that the current driving intensity index is too low, and at this time, the value of the current driving intensity index needs to be increased; on the contrary, if the current driving operation comfort index is higher than the comfort index range, it means that the current driving intensity index is too high, and at this time, the value of the current driving intensity index needs to be decreased.

[0054] Exemplary illustration: Increase or decrease the current driving intensity index according to a preset gradient, or, based on the preset gradient, adjust the preset gradient according to the difference between the current driving operation comfort index and the comfort index range, and increase or decrease the current driving intensity index according to the adjusted preset gradient; after adjusting the value of the current driving intensity index each time, return to step 202 until the newly calculated current driving operation comfort index is within the comfort index range.

[0055] For the above driving intensity index adjustment method, after detecting the update of the value of the current driving intensity index, calculate the driver's current driving operation comfort index at an interval of a first preset duration; if the current driving operation comfort index is within the preset comfort index range, no operation is performed; otherwise, feedback adjustment is performed on the current driving intensity index according to the current driving operation comfort index, so that the current driving operation comfort index is always maintained within the comfort index range. Compared with the related art, the above method improves the problem that it is difficult to match the actual power output and the actual power demand due to too high or too low driving intensity index, resulting in a decrease in the driver's driving operation comfort, and improves the driver's driving operation comfort.

[0056] In one embodiment, calculating the driver's current driving operation comfort index specifically includes the following steps: taking the moment when the value of the current driving intensity index is updated as the update moment, obtaining the current driving operation characteristics within a first preset duration after the update moment and the historical driving operation characteristics within a second preset duration before the update moment, where the driving operation characteristics include multiple characteristics that affect the driver's driving operation comfort; calculating the driver's current driving operation comfort index according to the difference between the current driving operation characteristics and the historical driving operation characteristics and the scoring weights corresponding to the preset driving operation characteristics.

[0057] Since the current driving operation characteristics are the driving operation characteristics related to driving operation comfort collected after the value of the current driving intensity index is updated, that is, after the power response parameters are updated, and the historical driving operation characteristics are the driving operation characteristics related to driving operation comfort collected before the value of the current driving intensity index is updated, that is, before the power response parameters are updated, the difference between the two can better reflect the comfort feeling of the driver when operating each functional component after the value of the current driving intensity index is updated, that is, after the power response parameters are updated; and different driving operation characteristics bring different driving operation comfort feelings to the driver. Therefore, for different driving operation characteristics, this application sets different scoring weights; and then calculates the driver's current driving operation comfort index according to the difference between the current driving operation characteristics and the historical driving operation characteristics and the scoring weights.

[0058] Among them, the second preset duration may be equal to the first preset duration, and the corresponding historical driving operation characteristics are the driving operation characteristics within the second preset duration before the update moment; the second preset duration may also be equal to the first preset duration multiplied by N, where N is an integer greater than 1, and the corresponding historical driving operation characteristics are the average value of the driving operation characteristics within the second preset duration before the update moment.

[0059] Exemplarily, it is assumed that the first preset duration is 10 hours, then the current driving operation characteristics are the driving operation characteristics within 10 hours after the update moment. It is assumed that the second preset duration is also 10 hours, then the historical driving operation characteristics are the driving operation characteristics within 10 hours before the update moment. It is assumed that the second preset duration is 100 hours, then N is equal to 10, and the value of the driving operation characteristics within 100 hours before the update moment is divided by 10, which is the historical driving operation characteristics.

[0060] The driving operation comfort index is related to the driver's driving operation characteristics, especially the driving operation characteristics corresponding to relatively large or small power demands. The driver's perception of driving operation comfort is more obvious during this process. Therefore, in one embodiment, the driving operation characteristics at least include: the first pedal switching times corresponding to the rapid acceleration switching to rapid deceleration, the first cumulative duration ratio corresponding to the throttle pedal opening degree being greater than the first preset throttle opening degree, the second cumulative duration ratio corresponding to the throttle pedal opening degree being less than the second preset throttle opening degree, the second pedal switching times corresponding to the rapid deceleration switching to rapid acceleration, the third cumulative duration ratio corresponding to the brake pedal opening degree being greater than the first preset brake opening degree, and the fourth cumulative duration ratio corresponding to the brake pedal opening degree being less than the second preset brake opening degree.

[0061] Among them, when switching from rapid acceleration to rapid deceleration, the corresponding pedal switching operation is as follows: the opening of the accelerator pedal increases from zero to greater than the first preset accelerator opening and then returns to zero, and the opening of the brake pedal increases from zero to greater than the first preset brake opening. The number of times corresponding to this pedal switching operation is the first pedal switching number; the proportion of the cumulative duration during which the accelerator pedal opening is greater than the first preset accelerator opening in the cumulative duration during which the accelerator pedal opening is greater than zero is the first cumulative duration proportion; the proportion of the cumulative duration during which the accelerator pedal opening is less than the second preset accelerator opening in the cumulative duration during which the accelerator pedal opening is greater than zero is the second cumulative duration proportion; when switching from rapid deceleration to rapid acceleration, the corresponding pedal switching operation is as follows: the opening of the brake pedal increases from zero to greater than the first preset brake opening and then returns to zero, and the opening of the accelerator pedal increases from zero to greater than the first preset accelerator opening. The number of times corresponding to this pedal switching operation is the second pedal switching number; the proportion of the cumulative duration during which the brake pedal opening is greater than the first preset brake opening in the cumulative duration during which the brake pedal opening is greater than zero is the third cumulative duration proportion; the proportion of the cumulative duration during which the brake pedal opening is less than the second preset brake opening in the cumulative duration during which the brake pedal opening is greater than zero is the fourth cumulative duration proportion. The above first preset accelerator opening is greater than the second preset accelerator opening, and the first preset brake opening is greater than the second preset brake opening.

[0062] In one embodiment, according to the difference between the current driving operation characteristics and the historical driving operation characteristics and the scoring weights corresponding to the preset driving operation characteristics, calculating the current driving operation comfort index of the driver includes: comparing the difference between the current driving operation characteristics and the historical driving operation characteristics with the same attributes with a preset threshold to determine the state characteristic value of the current driving operation characteristics; and calculating the current driving operation comfort index of the driver according to the state characteristic values of the current driving operation characteristics and the corresponding scoring weights.

[0063] The greater the difference between the current driving operation characteristics and the historical driving operation characteristics, the greater the difference in the operation amplitudes of the vehicle's various functional components before and after the numerical update of the current driving intensity index by the driver, and the more it can reflect the driver's feeling of driving operation comfort after the numerical update of the current driving intensity index. On the contrary, the smaller the difference, the smaller the difference in the operation amplitudes of the vehicle's various functional components before and after the numerical update of the current driving intensity index by the driver, and it cannot better reflect the driver's feeling of driving operation comfort after the numerical update of the current driving intensity index.

[0064] Therefore, for any set of current driving operation characteristics and historical driving operation characteristics with the same attributes, the difference between the two is compared with a preset threshold; when the difference is greater than or equal to the preset threshold, the corresponding current driving operation characteristics need to be used as an indicator for evaluating the current driving operation comfort index of the driver. Therefore, the state characteristic value of the current driving operation characteristics is assigned the first state value. For example, the first state value is 1, and this current driving operation characteristics will be considered when calculating the current driving operation comfort index later; when the difference is less than the preset threshold, the corresponding current driving operation characteristics do not need to be used as an indicator for evaluating the current driving operation comfort index of the driver. Therefore, the state characteristic value of the current driving operation characteristics is assigned the second state value. For example, the second state value is 0, and this current driving operation characteristics will not be considered when calculating the current driving operation comfort index later.

[0065] Among them, the present application sets state characteristic values for the current driving operation characteristics to mark whether the current driving operation characteristics are used to calculate the current driving operation comfort index after comparing the difference between the current driving operation characteristics and the historical driving operation characteristics with the preset threshold. Therefore, the first state value and the second state value corresponding to the state characteristic value respectively represent two marking states of "yes" and "no". The present application does not limit the specific values of the first state value and the second state value. In other embodiments, values such as "activated" and "not activated" can also be used to correspond to the two marking states of "yes" and "no" respectively, and only the current driving operation characteristics corresponding to the marking state of "yes" are used when calculating the current driving operation comfort index.

[0066] Driving operation characteristics with different attributes bring different driving operation comfort feelings to the driver. Therefore, for driving operation characteristics with different attributes, the present application sets different scoring weights; the specific values of the scoring weights corresponding to the driving operation characteristics of each attribute can be determined according to the degree of driving operation comfort feelings brought by the driving operation characteristics to the driver during the actual vehicle test; if the driving operation comfort feelings of the driver are more obvious, the scoring weight of the corresponding driving operation characteristics is greater; and the sum of the scoring weights corresponding to the driving operation characteristics of all attributes is equal to 100.

[0067] After determining the state characteristic values of the current driving operation characteristics of each attribute, the current driving operation comfort index of the driver is calculated according to the characteristic state values and scoring weights corresponding to the current driving operation characteristics of each attribute, that is: the current driving operation characteristics with the characteristic state value of the first state value are used as the target driving operation characteristics, and the scoring weights corresponding to the target driving operation characteristics are superimposed to obtain the current driving operation comfort index of the driver.

[0068] Taking the driving operation characteristics listed above as an example, assume that the difference between the current first pedal switching times and the historical first pedal switching times, the difference between the current first cumulative duration ratio and the historical first cumulative duration ratio, the difference between the current second pedal switching times and the historical second pedal switching times, and the difference between the current third cumulative duration ratio and the historical third cumulative duration ratio are all greater than the preset threshold, and the difference between the current second cumulative duration ratio and the historical second cumulative duration ratio and the difference between the current fourth cumulative duration ratio and the historical fourth cumulative duration ratio are both less than the preset threshold. Then, the state characteristic values corresponding to the current first pedal switching times, the current first cumulative duration ratio, the current second pedal switching times, and the current third cumulative duration ratio are all the first state values, and the state characteristic values corresponding to the current second cumulative duration ratio and the current fourth cumulative duration ratio are all the second state values. Then, adding up the scoring weights corresponding to the current first pedal switching times, the current first cumulative duration ratio, the current second pedal switching times, and the current third cumulative duration ratio can obtain the current driving operation comfort index of the driver.

[0069] In one embodiment, before the value of the current driving intensity index is updated, the method further includes: determining the start time of the current operation cycle, and calculating the first historical driving intensity index within a second preset duration before the start time; determining an optimization coefficient, where the value of the optimization coefficient is the initialization value or is determined according to the adjustment result of the driving intensity index of the previous operation cycle; updating the value of the current driving intensity index according to the product of the first historical driving intensity index and the optimization coefficient.

[0070] The above determination of the optimization coefficient specifically includes the following steps: If the current operation cycle is the first operation cycle, then assign the preset initialization value to the optimization coefficient; if the current operation cycle is not the first operation cycle, then obtain the adjustment result of the driving intensity index of the previous operation cycle and the second historical driving intensity index within a second preset duration before the start time of the previous operation cycle; assign the quotient obtained by dividing the adjustment result of the driving intensity index by the second historical driving intensity index to the optimization coefficient.

[0071] Among them, the adjustment result of the driving intensity index indicates: within the previous operation cycle, the driving intensity index that makes the driving operation comfort index of the driver within the comfort index range; the second historical driving intensity index is also used to multiply with the optimization coefficient within the previous operation cycle, and the obtained product is used to update the value of the driving intensity index of the previous operation cycle.

[0072] When updating the value of the current driving intensity index, it is necessary to refer to the driver's driving intensity index over a past period of time. Related technologies directly calculate the driving intensity index based on the vehicle behavior characteristics over a past period of time. The obtained value of the driving intensity index may be too low or too high. If the driver's power demand increases or decreases, it will be difficult to match the subsequent vehicle power output with the driver's power demand, reducing the driving operation comfort of the driver.

[0073] Therefore, in order to further improve this phenomenon, in this embodiment, a closed-loop control method is adopted. If the current operation cycle is the first operation cycle for the system to execute the driving intensity index adjustment method of this application, the value of the optimization coefficient at this time is the initialization value, such as 1; if the current operation cycle is not the first operation cycle, then in the previous operation cycle, by executing the driving intensity index adjustment method of this application, a corresponding driving intensity index adjustment result is generated, and the driving operation comfort index of the driver is within the comfort index range. Then, according to the driving intensity index adjustment result of the previous operation cycle, the optimization coefficient is determined; the value of the current driving intensity index is updated according to the product of the first historical driving intensity index and the optimization coefficient.

[0074] Through the method of this embodiment, on the basis of retaining the method of related technologies to update the current driving intensity index by referring to the driving intensity index over a past period of time, an optimization coefficient is newly added, and the optimization coefficient of the current operation cycle is updated according to the driving intensity index adjustment result of the previous operation cycle, so as to perform closed-loop control on the current driving intensity index of the current operation cycle, further ensuring that the current driving intensity index always remains within a numerical range that can keep the driving operation comfort index of the driver within the comfort index range, and improving the driving operation comfort of the driver.

[0075] In one embodiment, the value of the current driving intensity index is feedback-adjusted according to the current driving operation comfort index, which specifically includes the following steps: if the current driving operation comfort index is higher than the comfort index range, the value of the current driving intensity index is lowered according to the first preset coefficient and the difference between the current driving operation comfort index and the comfort index range; if the current driving operation comfort index is lower than the comfort index range, the value of the current driving intensity index is raised according to the second preset coefficient and the difference between the current driving operation comfort index and the comfort index range.

[0076] Exemplarily, taking the comfort index range of [30, 70] as an example, if the current driving operation comfort index is higher than the comfort index range, the value of the updated current driving intensity index = the value of the previous current driving intensity index * [1 - (current driving operation comfort index - 70) / 30 * 0.5], where the first preset coefficient is 1 / 60; if the current driving operation comfort index is lower than the comfort index range, the value of the updated current driving intensity index = the value of the previous current driving intensity index * [1 + (30 - current driving operation comfort index) / 30 * 1], where the second preset coefficient is 1 / 30.

[0077] After adjusting the value of the current driving intensity index, return to step 202, and repeat steps 202 to 206 until the value of the adjusted current driving intensity index makes the driver's driving operation comfort index within the comfort index range, and maintain the value of the adjusted current driving intensity index.

[0078] In the embodiment adopting closed-loop control, it is also necessary to output the first historical driving intensity index used in the current operation cycle, and output the value of the adjusted current driving intensity index as the driving intensity index adjustment result, so that in the next operation cycle, according to the first historical driving intensity index and the driving intensity index adjustment result of the current operation cycle, the above-mentioned closed-loop control implementation steps are used to perform closed-loop control on the driving intensity index of the next operation cycle.

[0079] Next, it will be combined with Figure 2 the flow schematic diagram of the driving intensity index adjustment method shown to illustrate an embodiment adopting closed-loop control:

[0080] In the first operating cycle when the vehicle controller executes the driving intensity index adjustment method of the present application, obtain the first historical driving intensity index within the second preset duration (such as 100 hours) before the start time. Its calculation method has been described above and will not be elaborated here; obtain the optimization coefficient. At this time, the value of the optimization coefficient is the initialization value, for example, 1; calculate the product of the first historical driving intensity index and the optimization coefficient; update the current driving intensity index according to the product; after the current driving intensity index is updated, at an interval of the first preset duration (such as 10 hours), calculate the current driving operation comfort index of the driver; determine whether the current driving operation comfort index is within the comfort index range; if the current driving operation comfort index is within the comfort index range, then keep the value of the current driving intensity index, so that the power system continues to use the current driving intensity index, and output the first historical driving intensity index, and output the adjusted current driving intensity index as the driving intensity index adjustment result; if the current driving operation comfort index is lower than the comfort index range, then increase the current driving intensity index, and return to the step of calculating the current driving operation comfort index of the driver at an interval of the first preset duration until the adjusted current driving operation comfort index is within the comfort index range; if the current driving operation comfort index is higher than the comfort index range, then decrease the current driving intensity index, and return to the step of calculating the current driving operation comfort index of the driver at an interval of the first preset duration until the adjusted current driving operation comfort index is within the comfort index range;

[0081] In the second operating cycle, obtain the first historical driving intensity index within the second preset duration (such as 100 hours) before the start time; calculate the quotient of the driving intensity index adjustment result of the previous operating cycle divided by the first historical driving intensity index of the previous operating cycle; update the quotient to the optimization coefficient of the current operating cycle; calculate the product of the optimization coefficient of the current operating cycle and the first historical driving intensity index of the current operating cycle; update the driving intensity index of the current operating cycle according to the product; the subsequent steps are the same as the relevant steps in the first operating cycle and will not be elaborated here; continuously repeat the above steps to form a closed-loop control of the driving intensity index.
