Description

Technical Field

[0001] The present application relates to the technical field of driving behavior restraint, and in particular to a vehicle driving restraint method and device. Background Art

[0002] With the rapid development of the automobile industry, the number of cars in my country is increasing. At the same time, with the gradual improvement of people's quality of life, the number of drivers is growing at a scale of tens of millions each year. The sharp increase in the number of cars and the rapid increase in the number of drivers have brought about traffic pressure and frequent traffic accidents, which have attracted great attention. How to effectively reduce the frequency of major traffic accidents, traffic accidents with heavy losses, and chain traffic accidents, and reduce the number of traffic casualties is particularly important. At present, some vehicles equipped with advanced driver assistance systems have functions such as lane departure warning, lane keeping assist, automatic emergency braking, adaptive cruise control, blind spot monitoring, lane change assist, and automatic parking. As part of the assisted driving system, these functions can help drivers detect potential dangers in a timely manner, thereby improving the comfort and safety of driving.

[0061] It is worth noting that with the rapid development of the automobile industry, the number of cars in my country is increasing. At the same time, with the gradual improvement of people's quality of life, the number of drivers is growing at a scale of tens of millions per year. The sharp increase in the number of cars and the rapid increase in the number of drivers have brought about traffic pressure and frequent traffic accidents, which have attracted great attention. How to effectively reduce the frequency of major traffic accidents, major loss traffic accidents, and serial traffic accidents, and reduce the number of traffic casualties is particularly important. At present, some vehicles equipped with advanced driver assistance systems have functions such as lane departure warning, lane keeping assist, automatic emergency braking, adaptive cruise control, blind spot monitoring, lane change assist, and automatic parking. These functions, as part of the assisted driving system, can help drivers detect potential dangers in time, thereby improving the comfort and safety of driving. However, in addition to natural factors (such as bad weather, natural disasters, etc.) and road factors (such as unreasonable road design, poor road conditions, etc.) that may cause traffic accidents, the root cause of most accidents lies in human factors. Human factors involve the driver's driving habits, concentration, reaction speed, awareness of traffic rules, and other aspects. These factors make the prevention and control of traffic accidents face huge challenges.

[0062] In response to the above problems, the embodiments of the present application propose a vehicle driving restraint method and device, which judge in real time whether the driver's vehicle driving behavior meets the corresponding safe driving conditions, and perform restraint processing on those that do not meet the corresponding safe driving conditions, thereby avoiding accidents and improving safety.

[0063] To facilitate the understanding of the present application, the technical solution provided by the present application is described in detail below in conjunction with specific embodiments.

[0064] See also Figure 1 , Figure 1 A flowchart of a vehicle driving constraint method provided in an embodiment of the present application.

[0065] like Figure 1 As shown in , the vehicle driving restraint method provided by the embodiment of the present application includes the following steps:

[0066] Step S101, based on the vehicle's driving-related parameters, determine whether the current vehicle driving behavior meets the corresponding safe driving conditions.

[0067] Here, the driving-related parameters of the vehicle may include, but are not limited to: the alcohol concentration in the driver's exhaled breath, the speed limit of the current vehicle's driving section, the current vehicle's driving speed, the distance between the current vehicle and the red light, the time when the green light in front of the current vehicle turns to the red light, the distance between the current vehicle and the surrounding vehicles, the lane the current vehicle is in, the traffic markings of the current vehicle's driving section, the current weather information, the distance between the current vehicle and the obstacle in front of the vehicle, and the distance between the current vehicle and the dangerous section in front of the vehicle. Safe driving conditions are a series of requirements set by this application based on actual experience to ensure the safe driving of vehicles on the road.

[0068] Regarding the alcohol concentration in the driver's exhaled gas, regarding step S101, in specific implementation, as an example, the following steps may be included:

[0069] First, determine whether the alcohol concentration in the driver's breath exceeds a preset threshold. Figure 2 As shown in , the vehicle is provided with a driver's alcohol sensor for detecting the alcohol concentration in the driver's exhaled breath. As an example, the driver's alcohol sensor is placed on the steering wheel.

[0070] Then, if the alcohol concentration in the driver's exhaled breath does not exceed the preset threshold, it is determined that the current vehicle driving behavior meets the safe driving conditions; if the alcohol concentration in the driver's exhaled breath exceeds the preset threshold, it is determined that the current vehicle driving behavior does not meet the safe driving conditions. Here, if the alcohol concentration in the driver's exhaled breath exceeds the preset threshold, it indicates that the vehicle driving behavior is drunk driving.

[0071] Regarding the speed limit value of the current vehicle driving section, regarding step S101, in specific implementation, as an example, the following steps may be included:

[0072] First, determine whether the current vehicle speed exceeds the speed limit of the current vehicle driving section. Figure 2 As shown in , the vehicle is provided with a camera for detecting the speed limit value of the current vehicle driving section. Specifically, on the one hand, the speed limit value of the current vehicle driving section can be determined by detecting the speed limit signs around the vehicle through the camera; on the other hand, the vehicle is provided with a radar sensor for detecting the current vehicle driving section, and the speed limit value of the current vehicle driving section is determined based on the corresponding relationship between the vehicle driving section and the speed limit value of the vehicle driving section.

[0073] Then, if the current vehicle speed does not exceed the speed limit of the current vehicle driving section, it is determined that the current vehicle driving behavior meets the safe driving conditions; if the current vehicle speed exceeds the speed limit of the current vehicle driving section, it is determined that the current vehicle driving behavior does not meet the safe driving conditions. Here, if the current vehicle speed exceeds the speed limit of the current vehicle driving section, it indicates that the vehicle driving behavior is speeding.

[0074] With respect to the current vehicle's speed, the distance between the current vehicle and the red light, and the time when the green light in front of the current vehicle turns into a red light, in the specific implementation, as an example, step S101 may include the following steps:

[0075] First, based on the current vehicle's speed, the distance between the current vehicle and the red light, and the time when the green light in front of the current vehicle turns to red, determine whether the vehicle can pass through the intersection before the red light turns on. Here, the distance between the current vehicle and the red light is obtained because: determine the distance the vehicle needs to go before passing through the intersection. The time when the current green light turns to red is obtained because: determine the time available for the vehicle to pass through the intersection. The distance that the vehicle can travel at the current speed during the time when the green light turns to the red light is calculated and compared with the distance from the current vehicle to the red light. The distance between the current vehicle and the red light is obtained by the camera. If the distance that the vehicle can travel during the time when the green light turns to the red light is greater than or equal to the distance between the vehicle and the red light, the vehicle can pass through the intersection before the red light turns on; otherwise, it cannot pass. As an example, assume that the current speed of the vehicle is 14m / s. At this time, the vehicle is 80m away from the red light at the intersection ahead, and the time when the green light turns to the red light is 4s. According to the current speed, the distance that the vehicle can travel within 4s is 14×4=56m. Since 56m is less than the 80m distance between the current vehicle and the red light, the vehicle cannot pass through the intersection before the red light comes on.

[0076] Then, if the vehicle can pass through the intersection before the red light comes on, it is determined that the current vehicle driving behavior meets the safe driving conditions; if the vehicle cannot pass through the intersection before the red light comes on, it is determined that the current vehicle driving behavior does not meet the safe driving conditions. Here, if the vehicle cannot pass through the intersection before the red light comes on, it indicates that the vehicle driving behavior is running a red light.

[0077] With respect to the driving speed of the current vehicle, the distance between the current vehicle and surrounding vehicles, and the driving speed of surrounding vehicles, regarding step S101, in specific implementation, as an example, the following steps may be included:

[0078] First, based on the current vehicle's speed, the distance between the current vehicle and surrounding vehicles, and the speed of surrounding vehicles, determine whether the vehicle can overtake. Here, the distance between the current vehicle and surrounding vehicles includes the distance between the vehicle in front, the vehicle behind, and the vehicle in the adjacent lane. Figure 2As shown in , the vehicle is equipped with an ultrasonic device for detecting the distance between the current vehicle and surrounding vehicles. The current vehicle's speed determines the time and acceleration required to complete the overtaking action; the distance between the current vehicle and surrounding vehicles clarifies the spatial range available for overtaking operations; the speed of surrounding vehicles clarifies the dynamic situation of the surrounding traffic flow, because during the overtaking process, the driving state of surrounding vehicles will have an impact on the overtaking behavior. Only when the current vehicle's speed is sufficient to complete the overtaking action at the right time, the distance from the surrounding vehicles can ensure sufficient safety space during the overtaking process, and the speed of surrounding vehicles will not cause dangerous situations such as excessive speed differences during the overtaking process, the vehicle is judged to be able to overtake, otherwise the overtaking behavior has a greater safety risk and is judged as not allowed to overtake.

[0079] Then, if the vehicle can overtake, it is determined that the current vehicle driving behavior meets the safe driving conditions; if the vehicle cannot overtake, it is determined that the current vehicle driving behavior does not meet the safe driving conditions. Here, if the vehicle cannot overtake, it indicates that the vehicle driving behavior is an overtaking behavior.

[0080] With respect to the lane in which the vehicle is currently located and the traffic markings of the road section on which the vehicle is currently traveling, regarding step S101, in specific implementation, as an example, the following steps may be included:

[0081] First, if it is detected that the current vehicle deviates from the lane in which the current vehicle is located, it is determined whether the vehicle turn signal lamp is turned on.

[0082] Then, if the vehicle turn signal is not turned on, the vehicle steering wheel is controlled to return to the center and / or the vehicle is controlled to send a deviation warning signal; if the vehicle turn signal is turned on, it is determined whether the traffic marking of the current vehicle driving section is a lane change prohibition line. Here, the vehicle steering wheel is controlled to return to the center so that the vehicle drives in the original lane, and the driver is not allowed to change lanes. As an example, the warning light alarms and emits a warning sound, and the deviation reminder "The vehicle is deviating, please drive carefully" is given.

[0083] Secondly, if the traffic markings on the current driving section of the vehicle are not lane change prohibition lines, it is determined that the current vehicle driving behavior meets the safe driving conditions; if the traffic markings on the current driving section of the vehicle are lane change prohibition lines, it is determined that the current vehicle driving behavior does not meet the safe driving conditions. Here, the lane change prohibition lines include: white solid lines, yellow solid lines, guide lines, dashed and solid lines, etc.

[0084] Regarding the current weather information, regarding step S101, in specific implementation, as an example, the following steps may be included:

[0085] First, based on the correspondence between weather information and vehicle speed limits, determine whether the current vehicle speed is within the vehicle speed limit corresponding to the current weather information. Weather information includes: rainy days, snowy days, foggy days, dusty days, and light intensity. Here, combined with actual experience, the vehicle speed limit is pre-set according to different weather information, and is used to measure whether the vehicle speed is safe in different weather conditions.

[0086] Then, if the current vehicle speed is within the vehicle speed limit corresponding to the current weather information, it is determined that the current vehicle driving behavior meets the safe driving conditions; if the current vehicle speed is not within the vehicle speed limit corresponding to the current weather information, it is determined that the current vehicle driving behavior does not meet the safe driving conditions. Here, based on the corresponding relationship between the weather information and the vehicle speed limit, it is determined that the current vehicle speed meets the safe driving conditions.

[0087] Regarding the distance between the current vehicle and the obstacle in front of the vehicle, regarding step S101, in specific implementation, as an example, the following steps may be included:

[0088] First, determine whether the distance between the current vehicle and the obstacle in front of the vehicle is within a first preset range. Here, as an example, the distance between the current vehicle and the obstacle in front of the vehicle is obtained by a camera. Obstacles include pedestrians and vehicles. Here, the first preset range is to ensure that the vehicle maintains a safe distance from the obstacle in front during driving.

[0089] Then, if the distance between the current vehicle and the obstacle in front of the vehicle is within a first preset range, it is determined that the current vehicle driving behavior meets the safe driving conditions; if the distance between the current vehicle and the obstacle in front of the vehicle is not within the first preset range, it is determined that the current vehicle driving behavior does not meet the safe driving conditions.

[0090] With respect to the current vehicle's speed, the distance between the current vehicle and the red light, and the time when the green light in front of the current vehicle turns into a red light, in the specific implementation, as an example, step S101 may include the following steps:

[0091] First, determine whether the distance between the current vehicle and the dangerous road section in front of the vehicle is within a second preset range. Here, the second preset range is to remind the vehicle that there is a dangerous road section in front of the vehicle so that the vehicle has enough time to make corresponding adjustments.

[0092] Then, if the distance between the current vehicle and the dangerous section of road ahead of the vehicle is within the second preset range, it is determined that the current vehicle driving behavior meets the safe driving conditions; if the distance between the current vehicle and the dangerous section of road ahead of the vehicle is not within the second preset range, it is determined that the current vehicle driving behavior does not meet the safe driving conditions.

[0093] Step S102: If the current vehicle driving behavior does not meet the corresponding safe driving conditions, an adjustment strategy for the vehicle is determined based on the current vehicle driving behavior, and the vehicle is adjusted according to the adjustment strategy. Here, the adjustment strategy is a series of methods and measures that can restore the vehicle to a safe driving state in response to the specific situation that the vehicle does not meet the safe driving conditions. If the current vehicle driving behavior meets the corresponding safe driving conditions, return to step S101.

[0094] Regarding the alcohol concentration in the driver's exhaled gas, regarding step S102, in specific implementation, following the above example, the following steps may be included:

[0095] If the current vehicle driving behavior does not meet the corresponding safe driving conditions, the adjustment strategy for the vehicle is determined based on the current vehicle driving behavior to control the vehicle to enter a locked state and / or control the vehicle to send a drunk driving reminder signal, and the vehicle is adjusted according to the adjustment strategy. Here, when the vehicle detects that the driver is driving under the influence of alcohol, it will enter a locked state. In this state, the vehicle cannot be started and the driver is prohibited from driving the vehicle. Specifically, for manual transmission vehicles, the system will control the gear position in the neutral position; for automatic transmission vehicles, the gear position will be controlled in the parking position. At the same time, the vehicle sends a drunk driving reminder signal. As an example, the warning light flashes and a warning sound is emitted. The drunk driving reminder "The driver has been detected to be driving under the influence of alcohol, and the vehicle has been locked."

[0096] Regarding the speed limit value of the current vehicle driving section, regarding step S102, in specific implementation, following the above example, the following steps may be included:

[0097] If the current vehicle driving behavior does not meet the corresponding safe driving conditions, the adjustment strategy for the vehicle is determined based on the current vehicle driving behavior to adjust the current vehicle's driving speed and / or control the vehicle to send a driving speed reminder signal, and the vehicle is adjusted according to the adjustment strategy. Here, a maximum speed threshold that the vehicle can travel is set, and the maximum speed threshold that the vehicle can travel is less than or equal to the speed limit of the current vehicle driving section. When the vehicle detects that the driver is speeding, the current vehicle's driving speed is reduced below the speed limit, and at the same time, the vehicle sends a driving speed reminder signal. As an example, assuming that the speed limit is 120km / h, the maximum speed threshold that the vehicle can travel is also set to 120km / h, the warning light flashes, and a warning sound is emitted, and the driving speed reminder "the speed limit of this section is 120km / h, and the maximum driving speed has been set to 120km / h".

[0098] With respect to the current vehicle's speed, the distance between the current vehicle and the red light, and the time when the green light in front of the current vehicle turns into a red light, regarding step S102, in specific implementation, following the above example, the following steps may be included:

[0099] If the current vehicle driving behavior does not meet the corresponding safe driving conditions, the adjustment strategy for the vehicle is determined based on the current vehicle driving behavior to control the vehicle to send a deceleration reminder signal, and the vehicle is adjusted according to the adjustment strategy. Here, as an example, the warning light flashes, and the vehicle sends a warning sound to slow down and remind "Red light ahead, please slow down."

[0100] With respect to the driving speed of the current vehicle, the distance between the current vehicle and surrounding vehicles, and the driving speed of surrounding vehicles, regarding step S102, in specific implementation, following the above example, the following steps may be included:

[0101] If the current vehicle driving behavior does not meet the corresponding safe driving conditions, the adjustment strategy for the vehicle is determined based on the current vehicle driving behavior to control the vehicle to send a warning signal prohibiting overtaking, and the vehicle is adjusted according to the adjustment strategy. Here, as an example, the vehicle sends a warning sound to prohibit overtaking, "The distance is too close to meet the overtaking, please drive carefully." If the current vehicle driving behavior meets the corresponding safe driving conditions, the overtaking route can be calculated based on the current vehicle's driving speed, the distance between the current vehicle and surrounding vehicles, and the driving speed of surrounding vehicles, and return to step S101.

[0102] With respect to the lane in which the vehicle is currently located and the traffic markings of the road section on which the vehicle is currently traveling, regarding step S102, in specific implementation, following the above example, the following steps may be included:

[0103] If the current vehicle driving behavior does not meet the corresponding safe driving conditions, the adjustment strategy for the vehicle is determined based on the current vehicle driving behavior, such as controlling the vehicle steering wheel to return to the center position and / or controlling the vehicle to send a lane change prohibition reminder signal, and the vehicle is adjusted according to the adjustment strategy. For example, the warning light flashes, and a warning sound is emitted, and a lane change prohibition reminder "Lane change is not allowed on this road section, please pay attention" is issued.

[0104] Regarding the current weather information, regarding step S102, in specific implementation, following the above example, the following steps may be included:

[0105] If the current vehicle driving behavior does not meet the corresponding safe driving conditions, the adjustment strategy for the vehicle is determined based on the current vehicle driving behavior to control the vehicle to send a driving speed reminder signal, and the vehicle is adjusted according to the adjustment strategy. As an example, the warning light flashes, assuming that in light rain, the vehicle's driving speed limit is 40-100km / h, that is, the vehicle emits a warning sound, and the driving speed reminder "The recommended vehicle speed is 40-100km / h".

[0106] Regarding the distance between the current vehicle and the obstacle in front of the vehicle, regarding step S102, in specific implementation, following the above example, the following steps may be included:

[0107] If the current vehicle driving behavior does not meet the corresponding safe driving conditions, the planned path of the vehicle is determined based on the distance between the current vehicle and the obstacle in front of the vehicle; based on the current vehicle driving behavior, the adjustment strategy for the vehicle is determined to control the vehicle to drive along the planned path, and the vehicle is adjusted according to the adjustment strategy. Here, when an emergency danger such as hands not on the steering wheel is detected, the vehicle will also plan the path. If the current vehicle driving behavior does not meet the corresponding safe driving conditions, the vehicle is temporarily taken over, and the vehicle drives along the planned path to ensure safety. During the takeover period, the double flash, steering wheel, brake, accelerator, etc. are in the takeover state and the driver cannot use them. The system will drive according to the calculated optimal safe route. When the danger is lifted, the driver is reminded to exit the takeover mode and drive by himself.

[0108] Regarding the distance between the current vehicle and the dangerous road section ahead of the vehicle, regarding step S102, in specific implementation, following the above example, the following steps may be included:

[0109] If the current vehicle driving behavior does not meet the corresponding safe driving conditions, the adjustment strategy for the vehicle is determined based on the current vehicle driving behavior to control the vehicle to send a dangerous road section warning signal, and the vehicle is adjusted according to the adjustment strategy. As an example, the warning light flashes, and a warning sound is emitted, and the dangerous road section reminds "the road ahead is a dangerous section, please pay attention".

[0110] In the embodiments of the present application, Figure 2 As shown in , as an example, the present application is provided with a positioning navigation for detecting the location of the vehicle. The present application can obtain the probability of traffic accidents in various areas of the local city where the vehicle is located through the positioning navigation of the vehicle. For locations with a high probability of accidents, the system will issue corresponding reminders to the vehicle.

[0111] like Figure 2As shown in , as an example, additionally, the present application may be provided with a client, a TSP platform and a screen. The user can issue remote control instructions through the client and view the vehicle condition information in real time on the client. The client establishes a communication connection with the TSP platform through 4G / 5G communication technology, and the TSP platform interacts with the vehicle system through the 4G / 5G network. Specifically, the TSP platform forwards the setting information and remote control instructions uploaded by the client to the vehicle system. At the same time, during the operation of the vehicle, various data acquisition devices continuously collect driving-related parameters and transmit them to the vehicle system for data collection and processing. The TSP platform collects vehicle information and driving-related parameters collected by various sensors, and sends them to the client at the same time. The vehicle system supports remote upgrades through OTA technology, which effectively guarantees the scalability of the system. The intelligent processing system in the vehicle system uses a constraint algorithm to analyze and judge the collected driving-related parameters. Once a situation that may affect driving safety is detected, the intelligent processing system will quickly start the warning sound and warning light, and at the same time put the vehicle into a constrained driving behavior mode, so as to achieve efficient management and safety assurance of vehicle driving. In addition, the vehicle system interacts with the screen through the GW gateway. The screen is mainly used for information display and human-computer interaction, providing users with a convenient and intuitive operating experience.

[0112] This application is based on a detailed data analysis of traffic accidents in the past 10-20 years, and takes into account data obtained from multiple factors such as traffic regulations, city characteristics, geographical environment, weather and climate, and driving habits of drivers, to design a constraint algorithm and apply it to the vehicle system.
