[0041] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with 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.

[0042] In one embodiment, Figure 1 As shown, a vehicle control method is provided. This embodiment uses the method applied to a vehicle control terminal as an example for illustration. It can be understood that the method can also be applied to a server, and can also be applied to a system including a vehicle control terminal and a server, and is implemented through the interaction between the vehicle control terminal and the server, including the following steps S202 to S208. Among them:

[0043] Step S202, obtaining the vehicle speed and weight corresponding to the vehicle.

[0044] Among them, the vehicle control terminal can be an electronic device set in the vehicle for controlling various components in the vehicle. The vehicle control terminal can communicate with the server in the cloud to share the information related to the vehicle's driving with the server in the cloud. When the vehicle is driving, it is easy to have accidents such as continuous rear-end collisions. In order to avoid accidents, the various steps provided in this embodiment can be used to provide the driver with more judgment time in an emergency, and to brake in advance in an emergency. Among them, when the vehicle is driving on the road, the sharing function of the vehicle's driving related information can be activated. And each vehicle on the road can activate the sharing function of driving related information. For example, the vehicle control terminal can pop up a corresponding interface to prompt the user to turn on the sharing function of driving related information. After the user triggers the consent operation, the vehicle control terminal can share the driving related information of the vehicle in real time to the server in the cloud. The server in the cloud can obtain the driving related information of each vehicle in real time, and provide the corresponding vehicle with the driving related information shared by other vehicles when necessary. After the vehicle turns on the sharing function, the vehicle control terminal can connect the vehicle to the network, and the connected network includes but is not limited to a satellite network, a communication service provider network, a regional static network, etc. During the process of establishing a connection with the network, the vehicle control terminal can perform normal physical identification with the network without data exchange.

[0045] In order to avoid accidents such as continuous rear-end collisions, the vehicle control terminal can perform analysis based on the driving information and weight information of the vehicle and other vehicles. For example, the vehicle control terminal can obtain the speed and weight of the vehicle. The speed corresponding to the vehicle represents the real-time speed of the vehicle where the vehicle control terminal is located, and the weight represents the overall weight of the vehicle where the vehicle control terminal is located. In some embodiments, the neighboring vehicles corresponding to the vehicle can share data such as the speed and weight of the vehicle. The neighboring vehicles represent other vehicles within a preset distance range of the vehicle, such as the vehicles around the vehicle, the front, the back, the left, and the right. The speed corresponding to the neighboring vehicle represents the real-time speed of the neighboring vehicle, and the weight of the neighboring vehicle represents the overall weight of the neighboring vehicle.

[0046] In one embodiment, the step of obtaining the vehicle weight corresponding to the vehicle includes: obtaining the deadweight corresponding to the above-mentioned vehicle, and obtaining the load corresponding to the above-mentioned vehicle; and obtaining the above-mentioned vehicle weight according to the sum of the above-mentioned deadweight and the above-mentioned load.

[0047] In this embodiment, the weight of the vehicle can be determined by the deadweight and the load of the vehicle. For example, the vehicle control terminal can obtain the deadweight corresponding to the vehicle and the load corresponding to the vehicle. The vehicle weight is obtained by summing the deadweight and the load. The deadweight refers to the weight of the vehicle itself, and the load refers to the weight of the contents carried by the vehicle.

[0048] Similarly, there may be multiple neighboring vehicles, and for each of the neighboring vehicles, the weight of the neighboring vehicle can be determined by the self-weight and load of the neighboring vehicle. For example, the vehicle control terminal of the neighboring vehicle can obtain the self-weight corresponding to the neighboring vehicle, and obtain the load corresponding to the neighboring vehicle. The weight of the neighboring vehicle is obtained according to the sum of the self-weight and the load. The neighboring vehicle can synchronize the speed and weight to the cloud server, so that the vehicle control terminal can obtain the real-time synchronized speed and weight of each neighboring vehicle from the cloud server to make judgments and analyses of emergency situations.

[0049] In some embodiments, the vehicle control terminal can synchronize the vehicle speed and weight to a cloud server in real time for other nearby vehicles to make judgments and analyses on emergency braking situations.

[0050] Step S204, determining a safe braking distance of the vehicle relative to the adjacent vehicles based on the vehicle speed and the vehicle weight; the adjacent vehicles represent other vehicles within a preset distance range of the vehicle.

[0051] Among them, after the vehicle control terminal obtains the above-mentioned vehicle speed and the above-mentioned vehicle weight, it can determine the safe braking distance. Among them, the safe braking distance means that when the adjacent vehicle brakes, the vehicle can brake safely and will not cause excessive braking force under the current speed and weight of the vehicle, that is, the safe braking distance needs to be greater than the braking distance of the vehicle. The braking distance means the distance required from the start of braking to the stop of the vehicle when the vehicle brakes at the current speed and weight. Then the vehicle control terminal can determine the safe braking distance of the above-mentioned vehicle relative to the above-mentioned adjacent vehicle based on the vehicle speed and the above-mentioned vehicle weight.

[0052] The vehicle control terminal can determine the braking distance of the vehicle by using the vehicle speed and vehicle weight, and determine the safe braking distance by querying the mapping relationship. Thus, the vehicle control terminal can determine the safe braking distance of the vehicle relative to the adjacent vehicle based on the above-mentioned braking distances.

[0053] Step S206, obtaining the distance between the vehicle and the adjacent vehicle.

[0054] The vehicle control terminal can obtain the distance between the vehicle and the adjacent vehicles in real time. The adjacent vehicles can be other vehicles in the front, back, left, and right positions within the preset distance range of the above-mentioned vehicle. The vehicle control terminal can obtain the distance between the vehicle and each adjacent vehicle, and then determine whether to brake based on each distance. In addition, the above-mentioned vehicle can upload the distance between the vehicle and the adjacent vehicle to the cloud server in real time, and the above-mentioned adjacent vehicle can upload the distance between the vehicle and other vehicles to the cloud server in real time. There are many ways to determine the above-mentioned vehicle distance.

[0055] For example, the vehicle control terminal can obtain the above-mentioned vehicle distances through satellite positioning; in addition, the vehicle control terminal can also collect the above-mentioned vehicle distances through distance sensors and other devices installed in the vehicle. The vehicle control terminal can combine satellite positioning and the vehicle distances collected by the sensor, perform comprehensive comparison and correction, and then determine the above-mentioned vehicle distances.

[0056] Step S208, controlling the vehicle to brake according to the emergency braking signal shared by the adjacent vehicles, the safe braking distance and the vehicle distance.

[0057] When the above-mentioned neighboring vehicle performs emergency braking, the emergency braking signal will be activated, so that the neighboring vehicle will share the emergency braking signal to the cloud server in real time, and the vehicle control terminal of the above-mentioned vehicle can obtain the emergency braking signal shared by the neighboring vehicle in real time. The above-mentioned emergency braking signal can be triggered by the AEB (Autonomous Emergency Braking, automatic emergency braking system) in the vehicle. For example, if the vehicle triggers the AEB pre-start signal, it is determined that the emergency braking signal is triggered; the above-mentioned emergency braking signal can be an emergency braking signal triggered by any neighboring vehicle in the forward direction of the above-mentioned vehicle. For example, the neighboring vehicles in front of the vehicle share the emergency braking signal several times in advance, and the vehicle can also respond to the emergency braking signal.

[0058] If the vehicle control terminal of the vehicle obtains the emergency braking signal shared by the neighboring vehicle, the vehicle control terminal can control the vehicle to brake according to the emergency braking signal, as well as the above-mentioned safe braking distance and vehicle distance. For example, when the vehicle control terminal detects the emergency braking signal of the neighboring vehicle, it can determine whether the vehicle is close to the safe braking distance according to the distance between the vehicle and the neighboring vehicle, and then determine whether braking is required, such as pre-starting AEB, to avoid accidents.

[0059] Specifically, the vehicle control terminal can synchronize the braking information of the continuous adjacent vehicles in front of the vehicle in real time, that is, the above-mentioned vehicle and the adjacent vehicles can synchronize the vehicle speed, braking signal, braking distance, etc. of the vehicle and the adjacent vehicles through real-time data synchronization in the cloud, so as to provide the fastest and most appropriate braking distance, also known as the safe braking distance, to the subsequent vehicles, avoiding the lack of emergency braking time, avoiding brake failure and power waste caused by too much and too early braking. In addition, the vehicle control terminal can also perform multi-dimensional safety distance and double verification. The vehicle control terminal not only verifies the safe distance between the vehicle and the adjacent vehicles in the same direction, but also performs four-dimensional, that is, the safe distance braking of the adjacent vehicles in front, behind, left and right, as well as the judgment relationship between power and distance, and provides braking prompts and the best distance for emergency braking intervention according to the weight and speed of each vehicle, such as the above-mentioned safe braking distance.

[0060] The vehicle control terminal ensures the common rail safety of vehicles by collecting the above-mentioned multiple data. That is, the vehicle control terminal calculates the common rail safety of the vehicle and adjacent vehicles through multiple data such as the front, rear, left, right, and right data of the vehicle, the vehicle weight, and the driving speed. The dynamic influence of vehicle weight and speed on the braking distance is considered in multiple data dimensions, and these data are put into a safe distance for analysis. Then the vehicle control terminal can determine the timing of braking initiation.

[0061] The above steps can be automatically activated and executed when the vehicle is driving, that is, the execution of the steps changes with the state of the vehicle. For example, when the vehicle is started, the execution of the above steps is turned on, and when the vehicle is turned off, the execution of the above steps is turned off.

[0062] In the above vehicle control method, the safe braking distance of the vehicle relative to the adjacent vehicle is determined based on the vehicle speed and weight, the distance between the vehicle and the adjacent vehicle is monitored in real time, and the vehicle is controlled to brake according to the emergency braking signal shared by the adjacent vehicle, the safe braking distance and the distance. Compared with the traditional control method based on the output prompt after the sensor detects the distance, this solution obtains information such as the vehicle speed, weight and the emergency braking signal shared by the vehicle, and uses the vehicle speed and weight to determine the safe braking distance. When the adjacent vehicle performs emergency braking, the vehicle can also perform corresponding braking control on the vehicle based on the shared emergency braking signal, thereby improving the safety of vehicle driving.

[0063] In one embodiment, the safe braking distance of the vehicle relative to the adjacent vehicle is determined based on the vehicle speed and the vehicle weight, including: querying a preset braking distance mapping table based on the vehicle speed and the vehicle weight to obtain a query result; the preset braking distance mapping table includes multiple mapping relationships between vehicle speed and vehicle weight and safe braking distance, and the safe braking distance is positively correlated with the vehicle speed and vehicle weight; based on the query result, the safe braking distance of the vehicle relative to the adjacent vehicle is obtained; the adjacent vehicle includes an adjacent vehicle adjacent to the vehicle in the traveling direction of the vehicle.

[0064] In this embodiment, the vehicle control terminal can determine the safe braking distance, also known as the optimal braking distance, based on the above vehicle speed and vehicle weight. For example, the vehicle control terminal can query the preset distance mapping table based on the vehicle speed and vehicle weight to determine the appropriate safe braking distance corresponding to the vehicle at different vehicle speeds and vehicle weights. Among them, different safe braking distances represent braking under different braking forces. Among them, the braking force represents the force and depth of the vehicle's brake pedal being stepped on. The greater the braking force, the smaller the braking distance, indicating that the braking is more urgent; the smaller the braking force, the larger the braking distance, indicating that the braking is less urgent, so the braking force corresponds to the braking distance from small to large. The braking distance represents the distance the vehicle moves forward from the start of braking to the stop of the vehicle. The vehicle control terminal can determine the corresponding safe braking distances based on each vehicle speed and vehicle weight in advance, and form the above preset braking distance mapping table.

[0065] Among them, the safe braking distance is positively correlated with the vehicle speed and weight, that is, the greater the vehicle weight and speed, the longer the required safe braking distance, so as to reduce the frustration caused by emergency braking under high speed and heavy weight conditions and improve the safety of braking; the smaller the vehicle weight and speed, the shorter the required safe braking distance, thereby improving the flexibility of braking.

[0066] In addition, in some embodiments, the above-mentioned preset braking distance mapping table may also include multiple mapping relationships between road scenes and safe braking distances, and also include multiple mapping relationships between tire types and safe braking distances. Among them, for dry or flat roads, the shorter the required safe braking distance is, the more flexibility during braking is improved; for uneven or slippery and icy roads, the longer the required safe braking distance is, the more safety is improved during braking. That is, the safe braking distance is negatively correlated with the flatness and dryness of the road surface; for tires with strong grip, the shorter the required safe braking distance is, the more flexibility during braking is improved; for tires with weak grip, the longer the required safe braking distance is, the more safety is improved during braking is improved. That is, the safe braking distance is negatively correlated with the grip performance of the tire.

[0067] Among them, the adjacent vehicles may include adjacent vehicles that are adjacent to the vehicle in the direction of travel. For example, it may be an adjacent vehicle that is in the same lane as the vehicle and in front of the vehicle. Thus, the vehicle control terminal can determine the safe braking distance of the vehicle relative to the adjacent vehicle based on the above query results. For example, when the adjacent vehicle brakes, the vehicle control terminal queries the preset braking distance mapping table based on the real-time collected vehicle speed and vehicle weight, and determines that the safe braking distance of the vehicle is 40 meters. Then, the vehicle control terminal can use the corresponding braking force based on the safe braking distance to determine when the vehicle needs to brake.

[0068] Specifically, the vehicle control terminal can share the braking force caused by the braking depth and its own driving speed in real time to the cloud server. Similarly, the vehicle's neighboring vehicles can also share the above information. The vehicle control terminal can also share the vehicle speed in real time with the vehicle's own weight and current load to the cloud server for vehicle safety braking analysis.

[0069] Through this embodiment, the vehicle control terminal can determine the optimal safe braking distance based on the vehicle speed and weight, and then the vehicle control terminal can control the vehicle to brake based on the safe braking distance and the emergency braking signal shared by adjacent vehicles, thereby improving the safety of vehicle driving.

[0070] In one embodiment, obtaining the distance between the vehicle and the adjacent vehicle includes: obtaining first positioning information corresponding to the vehicle and second positioning information corresponding to the adjacent vehicle; obtaining a first reference distance between the vehicle and the adjacent vehicle based on the first positioning information and the second positioning information; obtaining a second reference distance between the vehicle and the adjacent vehicle collected by a distance sensor in the vehicle; and determining the distance between the vehicle and the adjacent vehicle based on the first reference distance and the second reference distance.

[0071] In this embodiment, the vehicle control terminal can determine the distance between the vehicle and the neighboring vehicle based on multiple forms. For example, the vehicle control terminal can determine the distance between the vehicle and the neighboring vehicle by combining satellite positioning and distance information collected by the sensor. The vehicle control terminal can obtain the first positioning information corresponding to the vehicle and the second positioning information corresponding to the neighboring vehicle. Among them, the second positioning information can be the positioning information shared to the cloud server after the neighboring vehicle is connected to the network, so that the vehicle control terminal can obtain the first reference distance between the vehicle and the neighboring vehicle based on the first positioning information and the second positioning information. That is, the first reference distance is the distance determined based on satellite positioning.

[0072] The vehicle control terminal can also collect a second reference distance to the adjacent vehicle based on the distance sensor in the vehicle. Among them, the adjacent vehicle can be an adjacent vehicle adjacent to the above-mentioned vehicle in the direction of travel of the vehicle, such as an adjacent vehicle in front of the vehicle or an adjacent vehicle in front of the vehicle but in different lanes on the left and right. That is, the second reference distance can be a distance based on the sensor collection. The vehicle control terminal can determine the distance between the vehicle and the adjacent vehicle based on the above-mentioned first reference distance and second reference distance. For example, the vehicle control terminal can determine the smaller value of the first reference distance and the second reference distance as the distance between the vehicle and the adjacent vehicle, thereby reducing the measurement error of the distance and ensuring the safety of vehicle driving. Specifically, the vehicle control terminal can share the real-time distance with the vehicle in front and upload it to the server in the cloud in real time, so as to achieve the synchronization of the distance data and provide a basis for braking analysis of each vehicle.

[0073] Specifically, the vehicle control terminal can synchronize the vehicle distance data, for example, the real-time distance to the vehicle in front is continuously uploaded to the cloud server, and the first reference vehicle distance is obtained. The above distance acquisition device can be a radar set on the vehicle body, and the vehicle control terminal can obtain the distance between the vehicle, the front, the rear, the left and the right vehicles collected by the vehicle body radar to obtain the second reference vehicle distance, so that the vehicle control terminal can double-correct the above first reference vehicle distance and the second reference vehicle distance based on the vehicle body processor in the vehicle control terminal, and compare the correction data with the braking distance and the front and rear vehicle masses to perform braking control.

[0074] Through this embodiment, the vehicle control terminal can determine the distance between the vehicle and adjacent vehicles based on multiple forms, and then the vehicle control terminal can control the braking of the vehicle based on the distance and the emergency braking signal shared by the front vehicle, thereby improving the safety of vehicle driving.

[0075] In one embodiment, the vehicle is controlled to brake according to the emergency braking signal shared by the adjacent vehicles, the safety braking distance and the vehicle distance, including: if the emergency braking signal is the first emergency braking signal shared by any of the first adjacent vehicles, and the difference between the first vehicle distance and the first safety braking distance is less than or equal to a distance threshold, the vehicle is controlled to activate the emergency braking system for braking; wherein the first vehicle distance is the first vehicle distance between the vehicle and the adjacent first adjacent vehicle; and the first safety braking distance is the first safety braking distance of the vehicle relative to the adjacent first adjacent vehicle.

[0076] In this embodiment, the neighboring vehicles include first neighboring vehicles in the same lane in the direction of travel of the above-mentioned vehicle. For example, they may be first neighboring vehicles in front of the vehicle, and they are not necessarily in front of the vehicle, but may be first neighboring vehicles several vehicles ahead. The above-mentioned first neighboring vehicles may share the first emergency braking signal. For example, if the first neighboring vehicle triggers an emergency braking system such as AEB, the first neighboring vehicle shares the first emergency braking signal to the cloud server in real time.

[0077] The vehicle control terminal of the above-mentioned vehicle can detect that the shared emergency braking signal is the first emergency braking signal shared by any first adjacent vehicle, then the vehicle control terminal of the vehicle can obtain the first vehicle distance between the vehicle and the adjacent first adjacent vehicle, and obtain the first safety braking distance of the vehicle relative to the adjacent first adjacent vehicle of the vehicle. For example, the vehicle control terminal can obtain the first vehicle distance of the adjacent first adjacent vehicle directly in front of the vehicle and the first safety braking distance relative to the first adjacent vehicle. Therefore, the vehicle control terminal can further determine whether the difference between the first vehicle distance and the first safety braking distance is less than or equal to the distance threshold. If so, the vehicle control terminal can determine that the braking system needs to be pre-started, and the vehicle control terminal can control the vehicle to start the emergency braking system for braking, specifically, it can be AEB pre-start.

[0078] Specifically, after the first adjacent vehicle in front performs AEB pre-start, the AEB pre-start signal, braking distance, and braking timing can be shared through the network to obtain a shared emergency braking signal. The vehicle control terminal can pre-start AEB based on the AEB pre-start signal, braking distance, and braking timing in the emergency braking signal shared by the vehicle in front, combined with the above-mentioned safe braking distance, and then control the vehicle to brake at the appropriate time.

[0079] Through this embodiment, the vehicle control terminal can judge whether the vehicle itself needs emergency braking based on the emergency braking signal of the preceding vehicle in the same lane, thereby improving the timeliness of vehicle braking and improving the safety of vehicle driving.

[0080] In one embodiment, controlling the vehicle to brake according to the emergency braking signal shared by the above-mentioned adjacent vehicles, the above-mentioned safe braking distance and the above-mentioned vehicle distance also includes: if the above-mentioned emergency braking signal is the first emergency braking signal shared by any of the above-mentioned first adjacent vehicles, and the lane change signal of the above-mentioned second adjacent vehicle is detected, and the difference between the second vehicle distance and the second safe braking distance is less than or equal to the above-mentioned distance threshold, then controlling the above-mentioned vehicle to activate the emergency braking system for braking; the above-mentioned second vehicle distance is the second vehicle distance between the above-mentioned vehicle and the above-mentioned second adjacent vehicle; the above-mentioned second safety braking distance is the second safety braking distance of the above-mentioned vehicle relative to the above-mentioned second adjacent vehicle adjacent to the above-mentioned vehicle.

[0081] In this embodiment, the adjacent vehicles also include second adjacent vehicles in different lanes in the direction of travel of the above-mentioned vehicle. For example, the second adjacent vehicles in the left and right adjacent lanes in front of the vehicle and adjacent to the vehicle can be used. The above-mentioned first adjacent vehicles can share the first emergency braking signal, and when the second adjacent vehicle exists at this time, the original distance between the vehicle and the first adjacent vehicle in the same lane in front does not require braking, but due to the lane change of the second adjacent vehicle, the distance between the vehicle and the second adjacent vehicle will be shortened, and then the vehicle control terminal needs to further analyze whether braking is required.

[0082] The vehicle control terminal of the above-mentioned vehicle can detect that the shared emergency braking signal is the first emergency braking signal shared by any first adjacent vehicle, and the vehicle control terminal also detects the lane change signal of the second adjacent vehicle, then the vehicle control terminal of the vehicle can obtain the second vehicle distance between the vehicle and the adjacent second adjacent vehicle, and obtain the second safety braking distance of the vehicle relative to the adjacent second adjacent vehicle of the vehicle. For example, the vehicle control terminal can obtain the second vehicle distance of the second adjacent vehicle that is adjacent to the second adjacent vehicle in a different lane in the direction of travel of the vehicle, and obtain the second safety braking distance of the vehicle relative to the second adjacent vehicle. Therefore, the vehicle control terminal can further determine whether the difference between the second vehicle distance and the second safety braking distance is less than or equal to the distance threshold. If so, the vehicle control terminal can determine that the braking system needs to be pre-started, and the vehicle control terminal can control the vehicle to start the emergency braking system for braking, which can be specifically AEB pre-start.

[0083] Specifically, after the first adjacent vehicle in front performs AEB pre-start, the AEB pre-start signal, braking distance, and braking timing can be shared through the network to obtain a shared emergency braking signal. The vehicle control terminal can pre-start AEB based on the AEB pre-start signal, braking distance, and braking timing in the emergency braking signal shared by the vehicle in front, combined with the above-mentioned safe braking distance, and then control the vehicle to brake at the appropriate time.

[0084] Through this embodiment, the vehicle control terminal can judge whether emergency braking of its own vehicle is needed based on the emergency braking signal of the preceding vehicle in the same lane and the lane change signal of the adjacent vehicle in a different lane when it is detected at the same time, thereby improving the timeliness of vehicle braking and improving the safety of vehicle driving.

[0085] In an exemplary embodiment, Figure 2 As shown, Figure 2 The flowchart of the vehicle control method in another embodiment is shown in FIG. 1 . In this embodiment, the braking control of the vehicle control terminal can change with the startup state of the vehicle. For example, when the vehicle is driving, the judgment step of the braking control is automatically activated, and when the vehicle is not started, the judgment step is turned off. After activation, the vehicle control terminal can connect the vehicle to the network, covering three major mainstream networks: satellite network, communication service provider network, and regional static network, and perform normal physical identification without data exchange.

[0086] The vehicle control terminal can also synchronize braking data. For example, the vehicle control terminal uploads the braking force caused by the braking depth of the vehicle itself, combined with its own driving speed, to the cloud server. The vehicle control terminal can also synchronize speed data. The vehicle control terminal can upload the vehicle speed combined with the vehicle's own weight and current load to the cloud to achieve braking judgment.

[0087] The vehicle control terminal can also synchronize vehicle distance data. For example, the vehicle control terminal can continuously upload the real-time distance between the vehicle and the vehicle in front. The vehicle control terminal includes a body processor. While uploading various data, the vehicle control terminal also backs up the body processor, which temporarily stores the data.

[0088] When determining the distance between vehicles, the vehicle control terminal can obtain data based on the vehicle body radar, such as the vehicle body radar obtaining the distance between the front, rear, left and right vehicles, to obtain the second reference distance. The vehicle control terminal performs double correction on the backup data through the vehicle body processor. Specifically, during double correction, the vehicle control terminal performs double correction based on the first reference distance obtained from the cloud and the second reference distance data obtained by its own radar, obtains the above distance as the correction data, and compares the correction data with the braking distance and the mass of the front and rear vehicles.

[0089] When the vehicle control terminal detects that the AEB pre-start of the vehicle ahead is on, such as the AEB pre-start of the first adjacent vehicle, the vehicle control terminal can control the vehicle to perform AEB pre-start based on the AEB pre-start signal of the vehicle ahead and the optimal braking distance calculated above, also known as the safe braking distance.

[0090] The AEB pre-start signal of the vehicle in front can be connected to the network for sharing. The vehicle in front or several vehicles ahead can form an emergency braking signal with the AEB pre-start signal, braking distance, and braking timing, and share it through the network. Therefore, the vehicle control terminal can combine the emergency braking signal to pre-start the AEB of the vehicle, that is, according to the AEB pre-start signal of the vehicle in front and the optimal braking distance determined above, the above vehicle can pre-start the AEB, that is, control the vehicle to brake before the safe braking distance is about to be reached.

[0091] Through the above embodiment, the vehicle control terminal obtains information such as the vehicle speed, weight and emergency braking signal shared by the vehicle, and uses the vehicle speed and weight to determine the safe braking distance. When a neighboring vehicle performs emergency braking, the vehicle can also perform corresponding braking control on the vehicle based on the shared emergency braking signal, thereby improving the safety of vehicle driving.
