[0001] This invention relates to the field of vehicle technology, and more specifically to a vehicle control method, device, vehicle, and readable storage medium. Background Technology
[0002] Currently, vehicles play an increasingly important role in people's travel, and therefore, road safety is receiving more and more attention. Among various traffic accidents, the proportion caused by tire blowouts is also increasing year by year. Especially on highways, tire blowouts are one of the main causes of various serious traffic accidents, which seriously threaten people's lives and property.
[0003] With the development of the intelligent vehicle field, intelligent driving has become a hot topic. As an important component of strategic emerging industries, intelligent driving is a key integrated application of technology that has emerged during the transition from the internet era to the artificial intelligence era, and it is also one of the strategic high points of the new round of global economic and technological development. Intelligent driving is mostly used for vehicle assisted control. In existing technologies, after a tire blowout, intelligent control methods can be used to maintain the car's current direction of travel and gradually decelerate to a stop, thereby maintaining vehicle stability and improving driving safety.
[0004] However, using the aforementioned existing technologies, once a vehicle stops, it can easily affect vehicles traveling normally in the lane, increasing the risk of secondary accidents and resulting in lower driving safety. Summary of the Invention

[0015] When the lane departure state is "already deviated", obtain the vehicle's current speed;
[0016] If the driving speed is greater than or equal to a first threshold, the driving lane information is obtained.
[0017] Furthermore, the method also includes:

[0023] Optionally, determining the target parking rule based on the driving lane information includes:
[0024] If the driving lane information is the target lane, the target parking rule is determined to be the first rule; the first rule is used to make the vehicle stop directly in the current lane;
[0025] If the driving lane information is another lane, the target parking rule is determined to be the second rule; the second rule is used to cause the vehicle to change lanes to the target lane and stop.
[0026] Further, when the target parking rule is the second rule, controlling the vehicle to decelerate and stop to the target lane based on the target parking rule includes:
[0027] Obtain environmental information surrounding the vehicle;
[0028] If the environmental information meets the lane-changing conditions, control the vehicle to change lanes to the target lane;
[0029] After the vehicle reaches the target lane, control the vehicle to slowly decelerate and stop.
[0030] Optionally, the method further includes:
[0031] Confirm the driver's takeover status of the vehicle; the takeover status includes a driver not taking over status and a driver having taken over status;
[0032] If the takeover status is that the driver is not in a takeover state, a takeover prompt command is sent and the number of times the takeover prompt command is sent is accumulated;
[0033] If the number of transmissions is greater than or equal to the second threshold, the step of obtaining driving lane information is performed.

[0047] The embodiments of the present invention will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the scope of protection of the present invention.
[0048] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.
[0049] In the embodiments provided by the present invention, Figure 1 This is a flowchart illustrating a vehicle control method proposed in an embodiment of the present invention, applied to a vehicle controller. The method may include:
[0050] Step 101: Obtain the tire pressure value of each tire.
[0051] In embodiments of the present invention, tire pressure sensors are installed on each tire. These sensors acquire the tire pressure value of the corresponding tire and convert the pressure signal into an electrical signal, which is then sent to the vehicle controller. The vehicle controller acquires and identifies the electrical signal sent by the tire pressure sensor, thereby obtaining the tire pressure value. During actual measurement, the vehicle controller can acquire the tire pressure value at regular intervals, thus conserving its computational resources while ensuring measurement accuracy. Furthermore, the vehicle controller can mark the tire pressure sensors corresponding to each tire, allowing the tire pressure values sent by the sensors to be paired with tires in different locations for easier subsequent processing.
[0052] Step 102: In the event of a sudden change in at least one of the tire pressure values, obtain the driving lane information.
[0053] In embodiments of the present invention, after acquiring periodic tire pressure electrical signals, the vehicle controller can determine the state of these signals. If, within a certain segment of the tire pressure electrical signals, one tire pressure value is significantly lower than the others, it can be considered that a sudden change has occurred in the tire pressure. For example, under normal circumstances, the tire pressure sensor measures a tire pressure of 230 kPa, but in a certain measurement, the tire pressure is lower than 150 kPa; in this case, a sudden change in tire pressure can be considered. It should be noted that, under normal circumstances, the tire pressure measured by the tire pressure sensor will not be lower than atmospheric pressure. If, in a certain measurement, the tire pressure is lower than atmospheric pressure, it can be considered that the tire pressure sensor has malfunctioned and needs to be replaced promptly.
[0054] Meanwhile, in embodiments of the present invention, the acquired lane information may include the lane information of the road where the vehicle is currently located. If the vehicle is on a highway, the lane information of the vehicle can be obtained based on the vehicle's position and the highway's lane information. The vehicle controller can acquire a panoramic view of the vehicle based on the vehicle's panoramic camera, and then obtain the vehicle's current position based on the panoramic view. Thus, the lane information of the vehicle can be obtained based on the vehicle's current position and the lane information of the highway where the vehicle is located.
[0055] Step 103: Determine the target parking rule based on the driving lane information.
[0056] In embodiments of the present invention, a target parking rule is determined based on vehicle lane information. The driving lane information can be categorized according to the target parking lane information included in the target parking rule: one category is the target lane, and the other is other lanes. Each category of lane information corresponds to a parking rule. When the vehicle controller obtains the lane information currently in which the vehicle is located, it can match the corresponding parking rule based on the current lane information.
[0057] Step 104: Control the vehicle to decelerate and stop in the target lane based on the target parking rules.
[0058] In an embodiment of the present invention, after confirming the target parking rule, the vehicle controller can control the vehicle to execute the parking steps in the rule and complete the parking.
[0059] This invention provides a vehicle control method, comprising: acquiring the tire pressure values of each tire; acquiring driving lane information when at least one of the tire pressure values undergoes a sudden change; determining a target parking rule based on the driving lane information; and controlling the vehicle to decelerate and stop in the target lane based on the target parking rule. According to this method, after a sudden change in tire pressure, the vehicle's electronic stability control unit can take over the vehicle to actively control and stabilize the vehicle body, and can adopt corresponding parking rules based on the driving lane information to control the vehicle to stop in a relatively safe target lane. This avoids the risk of interfering with other vehicles in the lane and causing secondary accidents, thus improving driving safety.
[0060] In an embodiment of the present invention, Figure 2 This is a flowchart illustrating another vehicle control method provided in an embodiment of the present invention. The method may include the following steps:
[0061] Step 201: After the vehicle is powered on and started, obtain the tire pressure values of each tire.
[0062] In an embodiment of the present invention, the driver can start the vehicle. After the vehicle is started, the vehicle controller is powered on, and at this time, the vehicle controller can obtain the tire pressure value of each tire through the tire pressure sensor. The tire pressure sensor can be marked by the vehicle controller so that it can be associated one-to-one with the tire pressure value.
[0063] Step 202: In the event of a sudden change in at least one of the tire pressure values, confirm the lane departure status of the vehicle.
[0064] In an embodiment of the present invention, when one or more of the tire pressure values acquired by the vehicle controller undergo a sudden change, the vehicle controller can acquire a panoramic image of the vehicle taken by the panoramic camera on the vehicle. Since the vehicle does not immediately deviate from its lane after a sudden change in tire pressure, i.e., the process of the vehicle deviating from its lane is a state, based on this common sense, the vehicle controller can determine the lane departure state of the vehicle after acquiring the panoramic image. The lane departure state includes a non-deviated state and a deviated state. The non-deviated state may include a situation where the vehicle's driving trajectory has not changed significantly, while the deviated state may include a situation where the vehicle's driving trajectory has changed significantly.
[0065] In embodiments of the present invention, by confirming the vehicle's lane departure status, it is possible to more precisely determine whether the vehicle is out of control, which is beneficial for determining the timing of the vehicle controller to actively control the vehicle, avoiding unnecessary active control, helping the driver to remain calm, make reasonable driving behaviors, and ensure driving safety.
[0066] Step 203: If the lane departure state is "deviated", obtain the vehicle's speed.
[0067] In embodiments of the present invention, the vehicle controller can confirm the vehicle's lane departure status and determine whether the lane departure status is not a lane departure state or a lane departure state. When the vehicle controller confirms that the vehicle is currently in a lane departure state, it can acquire the vehicle's speed. In embodiments of the present invention, a speed measuring device is installed in the vehicle to measure the vehicle's speed. This speed measuring device may include a speedometer, a Global Positioning System (GPS), wheel speed sensors, etc. After the vehicle is started and powered on, the speed measuring device can be activated simultaneously to measure the speed. After acquiring the vehicle's current speed value, the speed measuring device can send the speed value to the vehicle controller for conditional judgment.
[0068] Specifically, step 203 may also include the following sub-steps:
[0069] Sub-step 2031: If the lane departure status is not deviated, confirm that the tire pressure sensor is in a faulty state.
[0070] Sub-step 2032 outputs a tire pressure sensor fault message.
[0071] In an embodiment of the invention, when the vehicle is not deviating from its current lane, it can be confirmed that the actual tire pressure value has not changed abruptly. However, if the tire pressure sensor sends an abnormal tire pressure value to the vehicle controller, it can be determined that the tire pressure sensor is faulty based on both the abnormal tire pressure value and the fact that the vehicle is not deviating from its current lane. When the tire pressure sensor is faulty, it interferes with the vehicle's active control. Therefore, upon confirming a tire pressure sensor malfunction, a tire pressure sensor malfunction warning message can be output to remind the driver to replace the damaged tire pressure sensor promptly.
[0072] In embodiments of the present invention, by confirming the vehicle's lane departure status, appropriate actions can be taken based on whether the lane departure status is confirmed or not. When the lane departure status is confirmed, a tire pressure sensor fault warning command is sent to prompt the driver to address the tire pressure sensor fault promptly. This facilitates timely fault handling and the timing of active control, reducing the possibility of accidents and ensuring driving safety. When the lane departure status is confirmed, the vehicle's current speed can be obtained, allowing for further assessment based on the speed.
[0073] Step 204: If the driving speed is greater than or equal to the first threshold, obtain the driving lane information.
[0074] In an embodiment of the invention, a speed value is calibrated by the vehicle controller and used as a first threshold. After acquiring the vehicle's speed, the vehicle controller can compare the vehicle's speed with the first threshold. When the vehicle's speed is greater than or equal to the first threshold, the vehicle controller can acquire a panoramic image of the vehicle captured by the panoramic camera, thereby obtaining the vehicle's current lane information based on the panoramic image and current road information.
[0075] In an embodiment of the present invention, the vehicle's lane departure status is confirmed when at least one of the tire pressure values changes abruptly; the vehicle's current driving speed is obtained when the lane departure status is confirmed; and the driving lane information is obtained when the driving speed is greater than or equal to a first threshold. This allows for more refined application scenarios of active control, avoids unnecessary active control actions, and ensures driving safety.
[0076] Specifically, step 204 may also include the following sub-steps:
[0077] Sub-step 2041: If the driving speed is less than the first threshold, send a vehicle alarm signal.
[0078] In an embodiment of the present invention, after acquiring the vehicle's speed, the vehicle controller can compare the vehicle's speed with a first threshold. If the vehicle's speed is less than the first threshold, the driver can fully control the vehicle without requiring active control from the vehicle controller. In this case, the vehicle controller can output a tire malfunction warning message, prompting the driver to stop the vehicle as soon as possible and address the malfunction.
[0079] In an embodiment of the present invention, by sending a vehicle alarm signal when the driving speed is less than a first threshold, the application scenarios of active control can be further refined, unnecessary active control actions can be avoided, and the driver can be promptly prompted to take reasonable control actions, which is beneficial to driving safety.
[0080] Sub-step 2042: If the driving speed is greater than or equal to the first threshold, control the vehicle to maintain the current driving path and activate the emergency alarm flashing lights.
[0081] In an embodiment of the invention, after acquiring the vehicle's speed, the vehicle controller can compare the speed with a first threshold. When the vehicle's speed is greater than or equal to the first threshold, the vehicle often loses balance, and due to the high speed, the driver cannot make the correct driving decisions based on the situation. In this case, the vehicle controller can take over the vehicle and maintain its current driving path. Simultaneously, it can activate emergency warning lights to alert other vehicles and prevent collisions or other accidents.
[0082] In an embodiment of the present invention, by controlling the vehicle to maintain its current driving path and activating the emergency warning flashing lights when the driving speed is greater than or equal to a first threshold, the vehicle's stability can be maintained when the driver cannot reasonably control the vehicle, and other vehicles on the road can be alerted, effectively reducing the possibility of traffic accidents and further ensuring driving safety.
[0083] Step 205: Classify the driving lane information.
[0084] In embodiments of the present invention, after obtaining the lane information of the vehicle, the lane information can be classified. From the perspective of lane information application, the lane information can be divided into target lane and other lanes. The target lane can be the lane where the vehicle eventually stops after being actively controlled by the vehicle controller, and other lanes can be the lanes where the vehicle needs to change lanes after being actively controlled by the vehicle controller.
[0085] Step 206: If the driving lane information is the target lane, determine the target parking rule as the first rule.
[0086] In embodiments of the present invention, the target parking rule may include a first rule and a second rule. The first rule guides the vehicle to stop directly in the current lane. When the vehicle controller determines that the vehicle is currently in the target lane, it can retrieve the first rule from the target parking rule and execute the control action specified in the first rule.
[0087] Step 207: Based on the first rule, control the vehicle to decelerate and stop in the target lane.
[0088] In embodiments of the present invention, the control action specified in the first rule may include controlling the vehicle to maintain its current lane and decelerate until it stops. After the vehicle controller retrieves the first rule, it can execute the control action specified in the first rule, thereby stopping the vehicle. The vehicle will eventually stop in the target lane, which is also the current lane.
[0089] Step 208: If the driving lane information is other lanes, determine the target parking rule as the second rule.
[0090] In embodiments of the present invention, the target parking rule may include a first rule and a second rule. The second rule guides the vehicle to change lanes to the target vehicle and stop. When the vehicle controller determines that the vehicle is currently in another lane, it can retrieve the second rule from the target parking rule and execute the control action specified in the second rule.
[0091] Step 209: Based on the second rule, control the vehicle to decelerate and stop in the target lane.
[0092] In an embodiment of the present invention, the control action specified in the second rule may include controlling the vehicle to change lanes to the target lane, and then maintaining the vehicle in the target lane while decelerating until it stops. After the vehicle controller retrieves the second rule, it can execute the control action specified in the second rule, that is, it can control the vehicle to change lanes to the target lane, and then control the vehicle to maintain the vehicle in the target lane while decelerating until it stops, and the vehicle will eventually stop in the target lane.
[0093] In an embodiment of the present invention, when the driving lane information is the target lane, the target parking rule is determined to be a first rule, and the vehicle is controlled to decelerate and stop to the target lane based on the first rule; when the driving lane information is another lane, the target parking rule is determined to be a second rule, and the vehicle is controlled based on the second rule. This allows for reasonable control based on the actual scenario in which the vehicle is located, avoiding possible secondary traffic accidents and ensuring driving safety.
[0094] Specifically, step 209 may also include the following sub-steps:
[0095] Sub-step 2091: Obtain environmental information surrounding the vehicle;
[0096] Sub-step 2092: If the environmental information meets the lane-changing conditions, control the vehicle to change lanes to the target lane.
[0097] Sub-step 2093: When the vehicle is in the target lane, control the vehicle to slowly decelerate and stop.
[0098] In embodiments of the present invention, after retrieving the second rule, the vehicle controller can execute the control actions specified in the second rule, controlling the vehicle to change lanes, decelerate, and stop. However, in practical applications, lane changing requires consideration of the environmental information surrounding the vehicle, which may include traffic flow information and obstacle information. The vehicle controller can control a panoramic camera to capture the environment around the vehicle, thereby obtaining a panoramic view of the vehicle, and then obtaining environmental information around the vehicle through the panoramic view. The vehicle controller can determine whether the current conditions for lane changing are met based on this environmental information. Specifically, when there are no other vehicles traveling around the vehicle and no other obstacles, the vehicle meets the conditions for lane changing. The vehicle controller can activate the right turn signal while controlling the vehicle to change lanes to remind other vehicles approaching during the lane change process. After completing the lane change, the vehicle controller can control the vehicle to decelerate slowly and stop the vehicle in the target lane.
[0099] It should be noted that, in the embodiments of the present invention, the target lane includes the rightmost lane and the emergency lane. Specifically, when an emergency lane exists in the road environment where the vehicle is currently located, the target lane can be the emergency lane; when an emergency lane does not exist in the road environment where the vehicle is currently located, the target lane can be the rightmost lane.
[0100] In embodiments of the present invention, by acquiring environmental information surrounding the vehicle, and when the environmental information meets the lane-changing conditions, the vehicle is controlled to change lanes to the target lane. Once the vehicle is in the target lane, it is controlled to gradually decelerate and stop. This effectively avoids secondary accidents that may occur during the active lane-changing process, thus improving driving safety. Furthermore, since some roads include emergency lanes, the target lane information is refined based on actual conditions. In real-world scenarios, the rightmost lane and emergency lane often have lower traffic volume. Therefore, using the rightmost lane and emergency lane as target lanes allows the vehicle controller to make reasonable active control actions based on actual conditions, reducing interference to other vehicles after the vehicle stops, further ensuring driving safety.
[0101] Step 210: After the vehicle is powered on and started, confirm the driver's control over the vehicle.
[0102] In an embodiment of the present invention, after the vehicle is powered on and started, the vehicle controller can also confirm the driver's takeover status of the vehicle. Specifically, the vehicle controller can detect control commands corresponding to the driver's control actions. For example, when the driver presses the accelerator pedal or rotates the steering wheel, the vehicle controller can receive the corresponding control commands. When the vehicle controller receives a control command, it can confirm that the vehicle is currently in a driver-in-control state; if the vehicle controller does not receive any control commands from the driver within a certain period of time, it can confirm that the vehicle is currently in a driver-out-of-control state.
[0103] Step 211: If the takeover status is "driver not in takeover status", send a takeover prompt command and accumulate the number of times the takeover prompt command is sent.
[0104] In an embodiment of the present invention, after confirming that the vehicle is currently in a driver-inactive state, the vehicle controller can send a takeover prompt command to remind the driver to take control of the vehicle in a timely manner. Simultaneously, the vehicle controller can record the cumulative number of takeover prompt command transmissions through an internal counting module. During the process of accumulating the number of takeover prompt command transmissions, if the vehicle controller receives a control command corresponding to a control action from the driver, it can reset the cumulative number of prompt command transmissions to 0.
[0105] Step 212: If the number of transmissions is greater than or equal to the second threshold, obtain the driving lane information.
[0106] In embodiments of the present invention, the vehicle controller may further define a specific positive integer as a second threshold. When the cumulative number of prompt commands sent is greater than or equal to the second threshold, the vehicle controller may actively control the vehicle and obtain the vehicle's current lane information. Lane information may include the target lane and other lanes.
[0107] In an embodiment of the present invention, by confirming the driver's takeover status of the vehicle, and when the takeover status is that the driver is not in a takeover state, a takeover prompt instruction is sent and the number of times the takeover prompt instruction is sent is accumulated. When the number of times the instruction is sent is greater than or equal to a second threshold, driving lane information is obtained. This allows for active control of the vehicle under special conditions where the driver cannot control it, further ensuring the safety of the driver and the vehicle.
[0108] In an embodiment of the present invention, Figure 3A flowchart illustrating a specific implementation of vehicle control is shown. In this embodiment, the vehicle is first started, thereby powering on the vehicle controller. The vehicle controller then acquires the tire pressure values of each tire and can confirm lane departure if at least one tire pressure value changes abruptly. If the lane departure status is confirmed to be normal, a tire pressure sensor malfunction is detected, and a tire pressure sensor malfunction warning command is sent. Alternatively, if the lane departure status is confirmed to be correct, the vehicle's current speed V is acquired. If V < N1, a vehicle alarm signal is sent to remind the driver to handle the malfunction. If V ≥ N1, the vehicle can be actively controlled to maintain its current driving direction, the hazard warning lights can be activated, and lane information can be acquired. After powering on, the vehicle controller can also confirm the driver's control status. If the driver has taken control, the driver's control status is continuously monitored. If the driver has not taken control, a takeover warning command is sent, and the cumulative number of takeover warning commands sent (N) is recorded. If N < N2, the driver's monitoring status continues to be monitored. If N ≥ N2, the vehicle can be actively controlled to maintain its current driving direction, the hazard warning lights can be activated, and lane information can be acquired. Afterwards, if the vehicle is in the target lane, it can be controlled to slow down and stop. If the vehicle is in another lane, the environmental information around the vehicle can be obtained, and the vehicle can be controlled to change lanes to the target lane if the environmental conditions meet the requirements for lane changing. Afterwards, the vehicle can be controlled to slow down and stop.
[0109] This invention provides another active control method, comprising: after the vehicle is powered on and started, acquiring the tire pressure values of each tire; if at least one of the tire pressure values changes abruptly, confirming the vehicle's lane departure status; if the lane departure status is confirmed, acquiring the vehicle's speed; if the speed is greater than or equal to a first threshold, acquiring lane information; classifying the lane information; if the lane information is a target lane, determining the target parking rule as a first rule; controlling the vehicle to decelerate and stop to the target lane based on the first rule; if the lane information is another lane, determining the target parking rule as a second rule; controlling the vehicle to decelerate and stop to the target lane based on the second rule; after the vehicle is powered on and started, confirming the driver's takeover status; if the takeover status is driver non-takeover status, sending a takeover prompt command and accumulating the number of times the takeover prompt command is sent; if the number of times the command is sent is greater than or equal to a second threshold, acquiring lane information. By following the steps above, the timing for active vehicle control can be determined from two different perspectives. This allows for more reasonable execution of active control under more appropriate conditions and enables the driver to make reasonable active control actions based on the actual road conditions. This can effectively reduce the possibility of secondary accidents and fully ensure the safety of the driver and the vehicle.
