[0055] To make the above and other features and advantages of this application clearer, the application is further described below with reference to the accompanying drawings. It should be understood that the specific embodiments given herein are for the purpose of explanation to those skilled in the art, and are exemplary only, not restrictive.

[0056] In the following description, numerous specific details are set forth to provide a thorough understanding of this application. However, it will be apparent to those skilled in the art that the specific details are not required to practice this application. In other instances, well-known steps or operations have not been described in detail to avoid obscuring this application.

[0057] The method for evaluating vehicle driving status provided in this application embodiment can be executed by the device for evaluating vehicle driving status provided in this application embodiment, which can be configured in a computer device.

[0058] refer to Figure 1 This application provides a method for evaluating the driving status of a vehicle, the method comprising the following steps S110 and S130.

[0059] S110: Obtain information on the changes in the accelerator and brake states of the vehicle within a preset time period.

[0060] The preset duration can be set according to actual needs. For example, the preset duration can be 10 minutes, 15 minutes, or other durations. The vehicle is equipped with an accelerator and brake pedals, such as a car or motorcycle. The status change information of the accelerator and brake pedals can be obtained by collecting parameters from the accelerator and brake pedals through the in-vehicle controller.

[0061] S130: Assess vehicle driving status based on throttle and brake state changes.

[0062] Vehicle driving states can be categorized into at least two types based on the driving conditions or scenarios the vehicle may be involved in. For example, daily driving can generally be classified into road conditions with frequent acceleration and deceleration and road conditions with frequent constant speed. Urban areas or winding roads are examples of road conditions with frequent acceleration and deceleration, while highways and rural roads are examples of road conditions with frequent constant speed. Road conditions with frequent constant speed can be further divided into cruising driving states. Road conditions with frequent acceleration and deceleration can be further divided into aggressive driving states with relatively sharp acceleration and deceleration and relaxed driving states with relatively gentle acceleration and deceleration. Specifically, the current vehicle driving state is determined by analyzing the changes in accelerator and brake pedal positions.

[0063] Specifically, steps S110 and S130 can be executed cyclically at set time intervals. That is, at each set time interval, information on the changes in the throttle and brake states within a preset duration prior to the current moment is acquired. For each acquired information on the changes in the throttle and brake states, step S130 is executed to continuously evaluate the vehicle state information. Furthermore, the set time interval can be equal to the preset duration, that is, information on the changes in the throttle and brake states is acquired once at each preset duration, thereby continuously acquiring state change information and evaluating the vehicle driving state.

[0064] The above-mentioned method for assessing vehicle driving status can accurately assess vehicle driving status by using throttle and brake status change information within a preset time period. It uses few parameters, is simple to calculate, does not require excessive computing power, can improve the assessment efficiency of vehicle driving status, and does not require external equipment to collect data, thus reducing hardware costs.

[0065] It is understood that, in another embodiment, steps S110 and S130 can also be executed in real time, that is, the throttle and brake state change information within a preset time period before the current moment can be obtained in real time, and the vehicle driving state can be evaluated based on the obtained throttle and brake state change information.

[0066] In one embodiment, step S110 may be preceded by: determining whether the vehicle is in a driving state; if so, then step S110 is executed.

[0067] Specifically, vehicle speed, energy consumption, and / or gear position can be used to determine whether a vehicle is in motion. For example, if the vehicle speed exceeds a speed threshold, it is considered to be in motion. By detecting whether the vehicle is in motion, the assessment of the vehicle's driving status is ensured, avoiding ineffective processing.

[0068] In one embodiment, the throttle and brake state change information includes: the number of times the throttle was operated, the number of times the brake was operated, and the average change gradient of the throttle and brake.

[0069] The number of times the accelerator is operated is the number of times the accelerator state changes to meet a first specified condition; the number of times the brake is operated is the number of times the brake state changes to meet a second specified condition. The accelerator and brake states are obtained by collecting parameters from the accelerator and brake pedals via the in-vehicle controller. Changes in the accelerator pedal parameters are used to determine whether the accelerator state changes meet the first specified condition, and changes in the brake pedal parameters are used to determine whether the brake state changes meet the second specified condition. Specifically, the first and second specified conditions can be set according to actual needs.

[0070] For example, the in-vehicle controller collects the opening of the accelerator pedal and the brake pedal. If the accelerator pedal opening increases from 0% to a value less than or equal to the maximum accelerator opening, and then returns to 0%, it indicates that the accelerator state change has met a first specified condition, and the accelerator pedal operation count is incremented by 1. Similarly, if the brake pedal opening increases from 0% to a value less than or equal to the maximum brake opening, and then returns to 0%, it indicates that the brake state change has met a second specified condition, and the brake pedal operation count is incremented by 1. It can be understood that the parameters of the accelerator and brake pedals can also be other types of data, such as accelerator pedal position and brake pedal pressure.

[0071] In one embodiment, the average gradient of the accelerator and brake pedals is the average of the positive gradients of the accelerator and brake pedals. The positive gradient of the accelerator pedal refers to the change in the opening of the accelerator pedal per unit time, i.e., the change in the opening of the accelerator pedal during the process of pressing the accelerator pedal; the positive gradient of the accelerator pedal is a positive value. Similarly, the positive gradient of the brake pedal refers to the change in the opening of the brake pedal per unit time, i.e., the change in the opening of the brake pedal during the process of pressing the brake pedal; the positive gradient of the brake pedal is a positive value.

[0072] It is understood that changes in throttle and brake opening include both positive changes (increasing opening) and negative changes (decreasing opening). A positive increase in opening corresponds to the pedal being depressed, while a negative decrease corresponds to the pedal automatically returning to its original position. Generally, the in-vehicle controller can collect pedal opening data in real time and calculate the throttle and brake change gradients. The throttle gradient includes both positive and negative throttle gradients, and the brake gradient includes both positive and negative brake gradients. Specifically, the positive throttle and brake gradients are statistically analyzed over multiple time units within a preset time period. The gradient data is then scattered according to the sampling rate, and the average value is calculated based on the discrete positive throttle and brake gradients within the preset time period. This yields the average gradient of the throttle and brake, thus using only the gradient of positive changes caused by human operation to calculate the average gradient for analyzing vehicle driving status, resulting in a more accurate analysis. For example, within a preset time period, the positive gradient of throttle change is sampled at a certain sampling frequency to obtain: X1, X2, ... Xi, and the positive gradient of brake change is obtained: Y1, Y2, ... Yn; then, the average value of the positive gradient of throttle change is a = (X1 + X2 + ... Xi) / i, the average value of the positive gradient of brake change is b = (Y1 + Y2 + ... Yn) / n, and the average gradient of throttle and brake change is (a + b) / 2; or the average gradient of throttle and brake change is (X1 + X2 + ... Xi + Y1 + Y2 + ... Yn) / (i + n).

[0073] In another embodiment, the average gradient of throttle and brake changes is the average of the absolute values ​​of the throttle and brake change gradients. Specifically, when calculating the throttle and brake change gradients, the absolute values ​​of each gradient (including both throttle and brake change gradients) are taken, and these absolute values ​​are scattered according to the sampling rate. The average value is calculated based on these discrete gradients over a preset time period to obtain the average gradient of throttle and brake changes. By calculating the average value based on the absolute values ​​of each gradient as the average gradient of throttle and brake changes, negative gradient values ​​during the throttle or brake return process can be avoided, which would cancel out the values ​​and affect the accuracy of the gradient calculation. For example, if the throttle change gradients are obtained within a preset time period: X1, X2, ..., Xi, and the brake change gradients are obtained: Y1, Y2, ..., Yn; then, the average value of the throttle change gradients is a = (|X1| + |X2| + ... + |Xi|) / i, the average value of the brake change gradients is b = (|Y1| + |Y2| + ... + |Yn|) / n, and the average change gradients of the throttle and brake are (a + b) / 2; or the average change gradients of the throttle and brake are (|X1| + |X2| + ... + |Xi| + |Y1| + |Y2| + ... + |Yn|) / (i + n).

[0074] The number of times the accelerator and brake are controlled can accurately reflect the amount of acceleration and deceleration of the vehicle within a preset time period. The average change gradient of the accelerator and brake can accurately reflect the urgency of acceleration and deceleration of the vehicle within a preset time period. By obtaining the number of times the accelerator and brake are controlled, as well as the average change gradient of the accelerator and brake, the overall acceleration and deceleration of the vehicle can be accurately analyzed.

[0075] In one embodiment, reference Figure 2 Step S130 includes steps S131 to S135.

[0076] S131: Based on the number of times the accelerator is controlled and the number of times the brake is controlled, determine whether the total number of times the accelerator is controlled and the number of times the brake is controlled reaches the first threshold.

[0077] Specifically, the sum of the number of times the accelerator was controlled and the number of times the brake was controlled is calculated to obtain the total number of times the accelerator was controlled and the brake was controlled, and then it is determined whether the total number of times the accelerator was controlled and the brake was controlled is greater than or equal to the first threshold n.

[0078] S133: Determine whether the average change gradient of the accelerator and brake reaches the second threshold.

[0079] Specifically, the average gradient of throttle and brake is compared with a second threshold x% per second to determine whether the average gradient of throttle and brake is greater than or equal to the second threshold x% per second.

[0080] It is understandable that there is no restriction on the order of execution of steps S131 and S133.

[0081] S135: When the total number of times the accelerator is operated and the total number of times the brake is operated reaches the first threshold, and the average change gradient of the accelerator and brake reaches the second threshold, the vehicle driving state is confirmed to be the preset first state.

[0082] The preset first state refers to a vehicle driving state characterized by a high frequency and intensity of acceleration and deceleration (e.g., sudden braking and acceleration), such as an aggressive driving state. Specifically, if the total number of times the accelerator and brake are operated reaches a first threshold n (i.e., greater than or equal to the first threshold), it indicates a high frequency of vehicle acceleration and deceleration; if the average change gradient of the accelerator and brake reaches a second threshold x% per second, it indicates relatively rapid acceleration and deceleration. When both conditions are met, the vehicle driving state is determined to be the preset first state, thus enabling the analysis of the first type of driving state.

[0083] In one embodiment, reference Figure 2 Step S130 includes step S132 after step S131.

[0084] S132. If the total number of times the accelerator is operated and the total number of times the brake is operated does not reach the first threshold, confirm that the vehicle driving state is the preset second state.

[0085] The preset second state represents a vehicle driving state with fewer accelerations and decelerations, such as cruise driving. Specifically, if the total number of times the accelerator and brake are operated does not reach the first threshold (i.e., the number of times the accelerator and brake are operated is less than the first threshold n), it indicates that the vehicle accelerates and decelerates less. In this case, the vehicle driving state can be determined to be the preset second state, thus realizing the analysis of the second driving state.

[0086] In one embodiment, reference Figure 2 Step S130 includes step S136 after steps S131 and S133.

[0087] S136: When the total number of times the accelerator is controlled and the total number of times the brake is controlled reaches the first threshold and the average change gradient of the accelerator and brake is less than the second threshold, confirm that the vehicle driving state is the preset third state.

[0088] The preset third state represents a vehicle driving state characterized by a high number of accelerations and decelerations with relatively smooth acceleration and deceleration, such as a relaxed driving state. Specifically, if the total number of times the accelerator and brake are operated is greater than or equal to a first threshold, it indicates that the vehicle accelerates and decelerates frequently; if the average change gradient of the accelerator and brake is less than a second threshold, it indicates that the vehicle accelerates and decelerates relatively smoothly. When both conditions are met, the vehicle driving state is determined to be the preset third state, thus realizing the analysis of the third driving state.

[0089] like Figure 2 As shown, the vehicle driving state is divided into three categories based on the number of times the accelerator is operated, the number of times the brake is operated, and the average change gradient of the accelerator and brake within a preset time period. The classification is simple and basically covers the three vehicle driving states of daily driving.

[0090] In one embodiment, the method for assessing the driving state of a vehicle further includes providing corresponding services to the driver based on the assessed driving state.

[0091] Here, "service" refers to the functional services provided by devices on the vehicle. Specifically, based on the assessed vehicle driving state, the system controls the devices to activate functional services corresponding to that driving state. For example, a vehicle device could be a massage seat, which can be controlled to provide massage services corresponding to the driving state. For instance, in aggressive driving mode, the massage seat could be controlled to operate in the first massage mode; in relaxed driving mode, in the second massage mode; and in cruise driving mode, in the third massage mode. Vehicle devices could also be in-vehicle multimedia systems, controlling the playback of music or display of prompts corresponding to the driving state. They could also be ambient lighting, controlling the ambient lighting to illuminate according to the driving state. It is understood that other services can also be provided based on the assessed vehicle driving state, such as those applied to vehicle suspension control and driving state-related linkage controls.

[0092] For example, the vehicle system categorizes songs into three genres based on song information or album information, corresponding to aggressive driving, relaxed driving, and cruise driving states respectively. Genres corresponding to aggressive driving include Electronic, Rock, and Schlager; those corresponding to relaxed driving include Pop and Country; and those corresponding to cruise driving include Jazz and Classical. After determining that the current driving state is aggressive, the system selects and plays songs from the genre library corresponding to aggressive driving to suit the current driving scenario.
