Description

Technical Field

[0001] This application belongs to the field of safe driving technology, specifically relating to a vehicle driving control method, a control system, and a vehicle. Background Technology

[0002] Since the advent of the first automobile after the Industrial Revolution, cars have evolved from zero-autonomous driving to semi-autonomous driving and then to fully autonomous driving. Driver assistance technology has been accompanying us and bringing us a better driving experience. As more information and content are provided to driver assistance systems, drivers' attention is also attracted by the variety of content inside the car, which reduces safety and increases the occurrence of traffic accidents, especially those caused by improper speed control.

[0003] Existing driving safety assistance systems typically predict risks and provide alerts by analyzing driver behavior, but lack analysis and judgment of objective driving conditions, resulting in poor safety assistance effectiveness. Other systems detect the distance between the vehicle and the vehicle in front, and calculate the vehicle's safe speed based on its own speed to control its own safe speed.

[0004] In summary, existing technologies fail to consider the combined influence of the vehicle's own condition and the external environment, leading to unreasonable judgments on safe driving and inaccurate calculations of driving speed, resulting in significant discrepancies with actual speed and directly impacting driving safety. Summary of the Invention

[0005] To address the shortcomings of the existing technology, this application provides a vehicle driving control method, a control system, and a vehicle. By comprehensively collecting data on road conditions and vehicle status, it determines a safe speed range suitable for the current road segment. This safe speed range provides more reasonable and precise driving guidance and is applicable to safe driving of any vehicle type in different scenarios.

[0006] To achieve the above objectives, this application provides a vehicle driving control method, comprising:

[0007] Read the driving data for the current road segment;

[0008] The current road safety factor and tire safety factor are obtained based on the driving data.

[0009] The current safe speed range is obtained based on the road safety factor and tire safety factor.

[0010] The vehicle is controlled to travel according to the current safe speed range.

[0011] This application obtains the safe speed range for each road segment by comprehensively considering the road conditions ahead and the vehicle's own condition during the driving process, thereby ensuring the safety of each journey. It is applicable to judging and analyzing various road conditions, meeting the needs of different driving intentions, and providing a more flexible and comprehensive guarantee for vehicle driving safety.

[0012] The driving data includes information on the road conditions ahead of the vehicle and the condition of each tire.

[0013] The road condition information ahead of the vehicle includes at least the road surface type, road surface smoothness, and road obstacles;

[0021] The maximum and minimum values ​​of the current safe speed range are obtained based on the current road safety factor and tire safety factor.

[0022] Then, the current safe speed range value is obtained based on the maximum and minimum values ​​of the current safe speed range. The current safe speed range value is then used as the preferred driving speed for this road segment and this type of road condition, thereby ensuring vehicle safety.

[0023] In this application, controlling vehicle movement based on the current safe speed range includes: sending the current safe speed range to an in-vehicle display or a vehicle control terminal in real time. Sending it to the in-vehicle display can be used to alert the driver or issue a safety warning; sending it to the vehicle control terminal enables safe control of the vehicle to ensure it operates in a safe state.

[0024] Furthermore, in this application, the step of controlling the vehicle to drive according to the current safe speed range value also includes: obtaining the current vehicle speed and determining whether the current vehicle speed is within the current safe speed range value;

[0025] If present, maintain the current driving mode;

[0026] If not, a warning message or an interactive command will be sent to the vehicle control terminal to adjust the current vehicle speed to within the current safe speed range value.

[0027] To address the aforementioned technical problems, this application also proposes a vehicle driving control system, preferably comprising:

[0028] The data reading module communicates with any sensor and reads the current driving data on the road surface;

[0029] The calculation module calculates the road safety factor and tire safety factor based on the driving data, and calculates the current safe speed range based on the current road safety factor and tire safety factor.

[0030] The interaction module, based on the current safe speed range, issues a warning to the in-vehicle display or sends an interaction command to the vehicle control terminal.

[0031] Optionally, the interaction module further includes a judgment unit, which can be used to generate an interaction command when the current vehicle speed exceeds the current safe vehicle speed range.

[0032] In this application, any sensor includes at least:

[0033] The first sensor is used to collect information about road conditions ahead of the vehicle;

[0034] And several second sensors, used to collect condition information of each tire.

[0035] To address the aforementioned technical problems, this application also proposes a vehicle comprising:

[0036] Multiple sensors are distributed at any location on the vehicle to collect driving data on the current road surface;

[0037] The in-vehicle display terminal is used to display the current safe speed range and warning prompts;

[0038] And the vehicle control terminal, used to adjust the current vehicle speed according to the received instructions;

[0039] The multiple sensors, the on-board display, and the vehicle control terminal are all communicatively connected to the vehicle driving control system and transmit data and / or commands.

[0040] Compared with the prior art, the advantages of this application are as follows:

[0048] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0049] Example 1:

[0050] As attached Figure 1 As shown, this embodiment provides a vehicle driving control method, which can be used for safe driving warnings in different driving modes. Based on the warning results, the vehicle driving control method is implemented. The method specifically includes:

[0051] S1: Read the current road driving data from various sensor terminals;

[0052] The driving data includes road condition information ahead of the vehicle and the condition information of each tire, specifically:

[0053] The road condition information ahead of the vehicle includes at least the road surface type, road surface smoothness, and road obstacles. In one embodiment, the road condition information ahead of the vehicle can be obtained by analyzing road surface images captured by the vehicle's front-end camera sensor through a cloud-based or vehicle-side processor to identify road surface features in the images. The road condition information obtained from the images may include, but is not limited to, road surface water accumulation, road surface silt, snow and ice coverage, road surface smoothness, road surface slope, road debris, and traffic congestion. The image analysis may employ either neural network learning or machine learning algorithms, which is not intended to limit this application.

[0054] The tire condition information includes at least the tire type, tire aging degree, and tire surface wear. In one embodiment, the tire condition information may include the tire brand, initial factory data, aging degree, tread depth, cumulative mileage, and tire operation data, etc., but is not limited to these.

[0055] S2: Obtain the current road safety factor and tire safety factor based on the driving data;

[0056] The specific methods for obtaining the current road safety factor and tire safety factor include:

[0057] The road condition information ahead of the vehicle and the tire condition information are analyzed to extract multiple road surface features and multiple tire features respectively.

[0058] Calculate the safety factor corresponding to each road surface feature and each tire feature. The safety factor of each road surface feature is obtained by comparing the collected road condition information with the database fingerprint. For example, if the road surface water detection in the road condition information shows no water accumulation, then the safety factor of that road surface feature is 100%. If a lot of water accumulation is detected, then the corresponding road surface feature safety factor is calculated according to the fitting, which is 80%, 60% or 40%, and so on, for the safety factors of other road surface features and the safety factors corresponding to tire features.

[0059] The road safety factor and tire safety factor are obtained by weighting the various safety factors. The weighted sum of all safety factors is 1. The weighting factors are set according to the influence of various characteristics on safe driving. The road safety factor and tire safety factor can also be calculated by weighting the various safety factors, but this is not limited in this embodiment.

[0060] S3: Obtain the current safe speed range value based on the road safety factor and tire safety factor;

[0061] Obtaining the current safe speed range specifically includes:

[0062] The maximum and minimum values ​​of the current safe speed range are obtained based on the current road safety factor and tire safety factor.

[0063] Then, the current safe speed range value is obtained based on the maximum and minimum values ​​of the current safe speed range. The current safe speed range value is then used as the preferred driving speed for this road segment and this type of road condition, thereby ensuring vehicle safety.

[0064] S4: Control the vehicle's movement according to the current safe speed range, specifically including:

[0065] Obtain the current vehicle speed and determine whether the current vehicle speed is within the current safe vehicle speed range.

[0066] If present, maintain the current driving mode;

[0067] If not, a warning message or an interactive command will be sent to the vehicle control terminal to adjust the current vehicle speed to within the current safe speed range value.

[0068] This embodiment collects driving data on the current road surface through sensors, comprehensively considers various factors affecting safe driving, and obtains a safe speed range for each road segment that is more in line with the actual situation, so as to ensure the safety of every driving journey. It is also suitable for judging and analyzing various road conditions, can meet different driving intentions, and more flexibly and comprehensively ensure vehicle driving safety.

[0069] It should be noted that during vehicle operation, tire conditions often show significant changes only after a period of time. Therefore, during vehicle control, the primary focus should be on road conditions ahead and any abnormalities caused by tires, while continuously monitoring tire conditions to improve tire safety and overall vehicle stability.

[0070] In some embodiments, the road condition information ahead of the vehicle and the condition information of each tire can be set according to multiple parameters that actually affect safe driving, and different parameters can be set according to different vehicle models and functions, and are not limited thereto.

[0071] In some embodiments, controlling vehicle movement based on the current safe speed range can also involve sending the current safe speed range to an in-vehicle display or vehicle control terminal in real time. Sending it to the in-vehicle display can be used to alert the driver or issue a safety warning; sending it to the vehicle control terminal enables safe control of the vehicle to ensure it operates in a safe condition.

[0072] As attached Figure 2 As shown, in some embodiments, step S1, obtaining road condition information ahead of the vehicle, may include:

[0073] S101: Activate the camera or radar to obtain road condition information at a preset distance from the current vehicle position;

[0074] S102: Supplement or correct road condition information based on current weather conditions or driving environment;

[0075] S103: Outputs the final road condition information ahead of the vehicle.

[0076] The current weather or driving environment conditions can be updated in real time through the cloud. The cloud supports communication with all vehicles and can also generate real-time road condition information for each road segment after obtaining the real-time road conditions collected by each vehicle. When any vehicle passes through or is about to pass through the corresponding road segment, the real-time road condition information of that road segment is downloaded from the cloud to supplement or correct the road condition information collected by the vehicle.

[0077] As attached Figure 3 As shown, in some embodiments, obtaining the condition information of each tire of the vehicle specifically includes:

[0078] S111: Activate the camera or radar to acquire information on the surface condition of each tire; for example, tire surface wear, aging degree, tread depth, etc. can be directly obtained from the images captured by the camera or radar to obtain the actual tire surface condition information.

[0079] S112: Load basic tire parameter information; such as tire brand, initial factory data, cumulative mileage, and historical tire operation data, etc.

[0080] S113: Combining steps S111 and S112, obtain and output the final condition information of each tire of the vehicle.

[0081] In this embodiment of the vehicle driving control method, step S2, calculating the current road surface safety factor and tire safety factor, specifically includes:

[0082] The safety factor is calculated for each of the extracted feature data points, and the calculation process is as follows:

[0083] The algorithm for the comprehensive road safety factor is as follows:

[0084] Let f L This represents the current road surface safety factor, calculated by considering the overall road surface safety factor f. s1 Environmental safety factor f c The Fa algorithm of factor analysis is used to calculate the current road safety factor f. L :f L =Fa{fs1, fc};

[0085] Among them, fs1, fc, etc. are all floating-point types in the range of 0~1. The road safety factor is obtained by weighted calculation method, where a1 is the weighted parameter of fs1, b1 is the weighted parameter of fc, and a1+b1=1.

[0086] The current road safety factor f L = (fs1*a1)+(fc*b1).

[0087] The calculation method for the overall tire safety factor is as follows:

[0088] Let fr represent the tire safety factor, which is determined by the overall safety system of the tire itself. s2 Tread depth coefficient fd, aging degree fo, and the tire safety factor fr are calculated using the Fb algorithm: fr=Fb{fs2, fd, fo};

[0089] Where fs2, fd, and fo are all floating-point numbers in the range of 0 to 1, the tire safety factor is obtained through a weighted calculation method. Where a2 is the weighted parameter of fs2, b2 is the weighted parameter of fd, and c2 is the weighted parameter of fo, and a2+b2+c2=1; then fr=(fs2*a2)+(fd*b2)+(fo*c2).

[0090] Formula for calculating the safe speed range, speed unit: km / h:

[0091] Let SL be the minimum safe speed in standard mode, and SH be the maximum safe speed in standard mode;

[0092] S[low]=(fL*a3+fr*b3)*SL;

[0093] Wherein, S[low] should be greater than or equal to the minimum speed SgL of the specified road section; if it is less than SgL, then S[low] = SgL.

[0094] S[high] = (fL*a3+fr*b3)*SH;

[0095] Wherein, S[high] should be less than or equal to the maximum speed Sgh of the specified road section; if it is greater than Sgh, then S[high] = Sgh.

[0096] In the above formula, a3 is the weighted parameter of fL, b3 is the weighted parameter of fr, and a3+b3=1.

[0097] In this embodiment of the vehicle driving control method, step S3, calculating the current safe speed range, specifically includes:

[0098] Finally, by combining the road surface safety factor and the tire safety factor, the speed range S [high~low] = Sp {fL, fr} from high to low safety is obtained;

[0099] The calculation formula includes safety factors for every tire and road surface data not listed. In actual operation, the data obtained will vary depending on road conditions or tire type. The example provided only illustrates a portion of key data for ease of understanding and should not be considered a limitation on the collected data.

[0100] Example 2:

[0101] like Figure 4 As shown, in another embodiment, the various safe driving control processes of the vehicle driving control method may further include the following specific processes:

[0102] Step 1: Start the vehicle; all sensors will then activate accordingly.

[0103] Step 2: The vehicle enters normal driving mode, and the central control unit begins to read the data information collected by each sensor.

[0104] The central control unit obtains data such as current vehicle speed, acceleration, and tire pressure to determine whether the vehicle has entered a normal driving state. Once in a normal driving state, the central control unit can obtain a safe travel strategy for the current vehicle driving control process based on the navigation information of this trip. It can also obtain historical road condition information based on historical records, including: dry cement road, wet cement road, dry asphalt road, etc.

[0105] It is understandable that road surface conditions are affected by various factors such as ground surface temperature and humidity, as well as atmospheric conditions, making it impossible to accurately determine the actual road surface condition solely based on road condition information. Therefore, this embodiment can also obtain the weather forecast for the current trip to predict environmental impact factors on road condition information.

[0106] Step 3: Obtain wheel speed. Obtain the current vehicle speed and send it to the central control unit for comparison with the current safe speed range. If the speed exceeds the current safe speed range, issue a safety warning or a speed control command.

[0107] Optionally, to further ensure driving safety and control vehicle speed in a timely manner, a setting can be made that if the vehicle speed is still detected to exceed the current safe speed range within a preset time after a safety warning is issued, the automatic control program will be activated, that is, the vehicle speed control command will be automatically triggered to complete the vehicle speed self-control process.

[0108] Example 3:

[0109] To address the aforementioned technical problems, this application also proposes a vehicle driving control system in another embodiment.

[0110] like Figure 5 As shown, the vehicle driving control system in this embodiment specifically includes the following:

[0111] The data reading module communicates with any sensor and reads driving data from the current road surface. In this embodiment, the arbitrary sensor includes at least: a first sensor for collecting road condition information ahead of the vehicle; and several second sensors for collecting condition information from each tire. The sensors are preferably cameras or radar devices, which can be distributed anywhere on the vehicle body; the models of the cameras and radar devices are not limited.

[0112] The calculation module calculates the current road safety factor and tire safety factor based on the driving data, and calculates the current safe speed range based on the current road safety factor and tire safety factor.

[0113] The interaction module, based on the current safe speed range, issues a warning to the in-vehicle display or sends an interaction command to the vehicle control terminal. The warning can be a voice announcement, an audible alert, a red speed display, or a flashing screen, and is not limited to any particular method. The interaction command can be an acceleration value; upon receiving this acceleration value, the vehicle control terminal completes a speed reduction control process within a preset time or along a specific road segment.

[0114] Figure 6 As shown, in a preferred embodiment, the sensor is a camera. The first sensor for acquiring visual road conditions is preferably a forward-facing camera for collecting road information ahead. The second sensor for acquiring visual tire road conditions is preferably two fisheye cameras on the rearview mirror for collecting the condition of the four tires.

[0115] When the car starts running, the vehicle speed control system activates, and the forward-facing camera begins to collect real-time data on the road ahead, sending the recorded video to the data reading module. Simultaneously, the fisheye cameras on the rearview mirrors also activate, recording video of the movement of all four tires and converting it into video and / or image data streams, which are then sent to the data reading module. At the same time, the vehicle's safety system data acquisition module begins collecting data from the tire pressure monitoring system and the road surface monitoring system, and sends this data to the data reading module.

[0116] The data reading module receives the transmitted data, extracts the road surface sub-information and tire sub-information that affect driving safety, and sends them to the algorithm analysis module.

[0117] The algorithm analysis module pre-judges the transmitted data to determine whether the data is sufficient. If the data is insufficient, it continues to acquire data. If the data is sufficient, it starts to calculate the security factor of the acquired data.

[0118] Furthermore, after the algorithm analysis module calculates the current safe speed range, the judgment module judges the obtained current vehicle speed range. If the current vehicle speed is not within the safe speed range, it is determined that there is an output result, and the safe speed range is pushed to the display module and the vehicle control interaction module.

[0119] The display module shows the safe speed range to the driver, and at the same time, the vehicle control interaction module issues commands to the vehicle control unit to control the vehicle speed according to the safe speed range.

[0120] Preferably, if the current vehicle speed is 70 km / h and the safe speed range displayed by the algorithm recognition module is 30 km / h to 50 km / h, then the vehicle control unit will automatically adjust the vehicle speed to 50 km / h.

[0121] Preferably, if the current vehicle speed is 70 km / h and the safe speed range displayed by the algorithm recognition module is 90 km / h to 110 km / h, then the vehicle control unit will automatically adjust the vehicle speed to 90 km / h.

[0122] Preferably, when the current vehicle speed is within a safe range, the algorithm analysis module continuously calculates the current safe vehicle speed range to ensure the vehicle's safe driving stability.

[0123] Furthermore, the driver can see the safe driving range through the display device and further control the vehicle speed.

[0124] It should be noted that the above embodiments are for illustrative purposes only and should not be considered as limiting the scope of this application. For example, in the described visual acquisition device, the preferred embodiment is one vehicle-mounted front camera and two rearview mirror fisheye cameras. Other preferred solutions, such as adding two front cameras or cameras to expand the detection range of the road surface, or installing four cameras near the tires, are all feasible solutions and also fall within the scope of this application.

[0125] In one embodiment, the interaction module further includes a judgment unit, which can be used to generate an interaction command when the current vehicle speed exceeds the current safe vehicle speed range.

[0126] Example 4:
