Description

Technical Field

[0001] This invention relates to the field of vehicle technology, specifically providing a vehicle and a method for controlling vehicle charging. Background Technology

[0002] Currently, with the development of technology, automobiles have become an indispensable means of transportation in people's lives. Based on different power systems, automobiles can be divided into piston-type internal combustion engine vehicles, electric vehicles, hybrid vehicles, etc.

[0003] Electric and hybrid vehicles contain high-voltage battery packs. In the event of a severe collision, the impact can cause a short circuit in the high-voltage circuitry, potentially leading to a fire or explosion of the entire vehicle. This is especially true when the vehicle is in the OFF position and unattended, during high-voltage charging. The presence of high-voltage electricity within the vehicle poses a significant danger in the event of a severe collision, impacting the safety of the vehicle and the surrounding environment.

[0004] However, existing airbag controllers are only activated after a collision, and then appropriate safety measures are taken based on the severity of the collision. This method has a significant delay, which prevents the vehicle from taking safety measures immediately after a collision, thus failing to protect the vehicle, battery, and surrounding environment in a timely manner.

[0005] Therefore, there is an urgent need for a vehicle charging control method to solve the above-mentioned technical problems. Summary of the Invention

[0024] When the collision intensity exceeds the third preset threshold, the collision information is sent to the user or the backend so that the user can handle the damaged vehicle; lowering the trigger threshold of the collision output signal means lowering the third preset threshold.

[0025] In a specific implementation of the above-mentioned vehicle charging control method, "determining the safety measures that the vehicle needs to take based on the degree of collision" includes:

[0026] When the collision intensity is greater than the fourth preset threshold, the battery airbag and the passenger compartment airbag are activated by control. The fourth preset threshold is greater than the first preset threshold. Lowering the trigger threshold for the collision output signal means lowering the fourth preset threshold.

[0027] In a second aspect, the present invention provides a vehicle including a controller, the controller including the control module, the vehicle being capable of performing the vehicle charging control method as described above.

[0028] In a specific embodiment of the vehicle described above, the vehicle includes a detection component, a collision detection device, and a charging controller, wherein the detection component, the collision detection device, and the charging controller are all communicatively connected to the controller.

Lowering the trigger threshold allows the vehicle to quickly take safety measures in the event of a collision, protecting personal and property safety. Because the probability of detecting a collision in advance is relatively high, lowering the trigger threshold almost eliminates the possibility of accidental operation.

[0095] In existing vehicles, the airbag controller is only activated after a collision, and then appropriate safety measures are taken based on the severity of the collision. This method has a significant delay, preventing the vehicle from taking safety measures immediately after a collision, thus failing to protect the vehicle, battery, and surrounding environment in a timely manner. To solve the above problems, this invention discloses a vehicle and a vehicle charging control method.

[0096] Example 1

[0097] This embodiment discloses a vehicle charging control method. The vehicle is specifically a pure electric vehicle or a hybrid electric vehicle equipped with a battery that requires a charging station to charge. The vehicle can detect its surrounding environment, specifically through radar and cameras, primarily detecting the position and movement of objects around the vehicle to determine the likelihood of a collision. The vehicle includes a controller, specifically an airbag controller, which is mainly used to determine whether to deploy the airbags based on the collision situation.

[0098] like Figure 1 As shown, the control method includes:

[0099] S1. Determine the probability of a collision based on the surrounding environment of the vehicle;

[0100] The surrounding environment mainly refers to objects around the vehicle, especially moving objects; particularly moving vehicles such as electric vehicles, tricycles, and cars. The likelihood of a collision is determined by analyzing the distance between the objects and the vehicle, the direction of the objects' movement, and their relative speed. If the distance between the object and the vehicle is less than a preset distance, the object is moving towards the vehicle, and its speed is greater than a preset speed (a speed greater than the preset speed allows the object to collide with the vehicle due to its own inertia; if the object also has a power source, the probability of collision is even greater), then it is determined that the object is very likely to collide with the vehicle, meaning the probability of collision is greater than the first preset probability.

[0101] S2. Determine whether to wake up the controller based on the probability of a vehicle collision and the vehicle's charging status.

[0102] "Determining whether to wake up the controller based on the probability of a collision and the vehicle's charging status" specifically includes: if the probability of a collision is greater than a first preset probability, and the vehicle is charging, then the controller is woken up. Waking up the controller ensures it is always ready to process data and send collision output signals, enabling a rapid response and shortening response time in the event of a collision.

[0103] "Determine whether to wake up the controller based on the probability of a vehicle collision and the vehicle's charging status" specifically includes: if the probability of a collision is not greater than a first preset probability or the vehicle is not charging, then there is no need to wake up the controller.

[0104] The control method also includes: S3, determining whether to lower the trigger threshold of the collision output signal based on the probability of a vehicle collision and the state of the controller.

[0105] "Determining whether to lower the collision output signal trigger threshold based on the probability of a vehicle collision and the controller's status" specifically includes:

[0106] If the probability of a collision is greater than the second preset probability, and the controller is in a wake-up state, then the trigger threshold of the collision output signal is lowered. Lowering the trigger threshold enables the vehicle to take safety measures quickly in the event of a collision, thereby protecting personal and property safety.

[0107] When a potential collision is not detected in advance but a collision actually occurs, the necessary safety measures are determined based on the severity of the collision. If the collision severity exceeds a first preset threshold, the vehicle's charging and high-voltage power are cut off; if it exceeds a second preset threshold, warning lights are illuminated and the horn sounds; if it exceeds a third preset threshold, collision information is sent to the user or backend so the user can handle the damaged vehicle. The second and third preset thresholds can be the same as or higher than the first preset threshold. If the collision severity exceeds a fourth preset threshold, the battery airbag and passenger airbag are deployed; the fourth preset threshold is higher than the first preset threshold. That is, deploying the battery airbag and passenger airbag when the collision is severe protects the battery and the occupants in the passenger compartment. This invention lowers the trigger thresholds of the output signal by reducing the first, second, third, and fourth preset thresholds, enabling the vehicle to quickly take safety measures to protect personal and property safety upon collision. Since the probability of early collision detection is relatively high, lowering the trigger thresholds almost eliminates the possibility of misoperation.

[0108] "Determine whether to lower the collision output signal trigger threshold based on the probability of a vehicle collision and the controller status" specifically includes: if the collision probability is not greater than the second preset probability, or the controller is not in a wake-up state, then there is no need to lower the collision output signal trigger threshold.

[0109] like Figure 2 As shown, the control method also includes:

[0110] S4. Determine the degree of vehicle collision based on collision data and environmental data. Collision data specifically includes data collected by collision sensors and acceleration information collected by the central acceleration sensor. Environmental data primarily serves as a reference, mainly for identifying the objects colliding with the vehicle; collision data is the primary factor in determining the degree of collision.

[0111] S5. Determine the safety measures that need to be taken for the vehicle based on the severity of the collision.

[0112] "Determining the necessary safety measures for the vehicle based on the severity of the collision" specifically includes:

[0113] When the collision severity exceeds the first preset threshold, the charging and high-voltage power to the vehicle are cut off. When the collision severity exceeds the second preset threshold, the warning lights illuminate and the horn sounds. When the collision severity exceeds the third preset threshold, collision information is sent to the user or the backend so that the user can handle the damaged vehicle. The second and third preset thresholds can be the same as or greater than the first preset threshold. When the collision severity exceeds the fourth preset threshold, the battery airbag and passenger compartment airbag are deployed; the fourth preset threshold is greater than the first preset threshold. That is, deploying the battery airbag and passenger compartment airbag when the collision severity is relatively severe can protect the battery and the occupants in the passenger compartment. If the collision severity is not greater than the first preset threshold, no safety measures are required. This means that the collision severity is low, such as a collision with a basketball or soccer ball, a door opening, a minor collision with a person, or a minor collision with a bicycle tire. Low-severity collisions do not affect vehicle safety, therefore no safety measures are necessary.

[0114] Lowering the trigger threshold for the collision output signal includes lowering a first preset threshold, a second preset threshold, a third preset threshold, and a fourth preset threshold. Specifically, if the probability of a collision is greater than the second preset probability, and the controller is in a wake-up state, then the first, second, third, and fourth preset thresholds are lowered.

[0115] like Figure 3 As shown, the vehicle charging control method specifically includes the following steps:

[0116] S01. Determine the probability of a collision based on the surrounding environment of the vehicle;

[0117] S02. Determine whether the probability of collision is greater than the first preset probability. If yes, proceed to step S03; otherwise, proceed to step S04.

[0118] S03. Determine whether the vehicle is charging. If yes, proceed to step S05; otherwise, proceed to step S04.

[0119] S04, No need to wake up the controller.

[0120] S05. Wake up the controller, then proceed to step S06.

[0121] S06. Determine if the collision probability is greater than the second preset probability. If so, proceed to step S07.

[0122] S07. Reduce the trigger threshold of the collision output signal.

[0123] S08. Determine the extent of the vehicle collision based on the collision data and environmental data;

[0124] S09. Determine whether the collision degree is greater than the first preset threshold. If so, proceed to step S10.

[0125] S10. Disconnect the charging and high-voltage power to the vehicle; then proceed to step S11.

[0126] S11. If the collision level is greater than the second preset threshold, proceed to step S12.

[0127] S12. Turn on the warning light and sound the horn, then proceed to step S13.

[0128] S13. If the collision level is greater than the third preset threshold, proceed to step S14.

[0129] S14. Send the collision information to the user or the backend so that the user can handle the damaged vehicle; then proceed to step S15.

[0130] S15. Determine whether the collision degree is greater than the fourth preset threshold. If so, proceed to step S16.

[0131] S16, control the detonation of the battery airbag and the cab airbag.

[0132] Example 2

[0133] This embodiment discloses a vehicle, specifically a pure electric vehicle or a hybrid electric vehicle, equipped with a battery that requires a charging station to charge. The vehicle can detect its surrounding environment, primarily detecting the position and movement of objects in the vicinity to determine the likelihood of a collision. Figure 4 As shown, the vehicle specifically includes a detection component, a charging controller, and a controller; wherein the controller is an airbag controller. The vehicle is capable of executing the vehicle charging control method described in Embodiment 1. The control module is integrated within the airbag controller.

[0134] The detection component can detect the environment surrounding the vehicle and determine the probability of a collision. The surrounding environment mainly refers to objects around the vehicle, especially moving objects, particularly moving vehicles such as electric vehicles, tricycles, and cars. It analyzes the distance between the objects and the vehicle, the direction of the objects' movement, and the relative speed between the objects and the vehicle to determine whether a collision will occur. If the distance between the object and the vehicle is less than a preset distance, the object is moving towards the vehicle, and the object's speed is greater than a preset speed (a speed greater than the preset speed allows the object to collide with the vehicle due to its own inertia; if the object also has a power source, the probability of a collision is even greater), then it is determined that the object is very likely to collide with the vehicle, meaning the collision probability is greater than a first preset probability.

[0135] The detection components include radar and cameras, which work together to detect the vehicle's surroundings. Specifically, the camera takes pictures and identifies objects based on image recognition. The radar detects the distance, direction of movement, and speed of objects. The radar and camera communicate with each other and analyze the data, sending the overall result—the probability of a collision—to the airbag controller to trigger its activation.

[0136] The charging controller is specifically responsible for controlling whether the battery is charged, determining the battery's charging data, and detecting the battery's status.

[0137] Both the detection components and the charging controller are connected to the controller via communication, specifically through the vehicle's CAN bus.

[0138] The system determines whether to wake up the controller based on the probability of a collision detected by the detection component and the charging status detected by the charging controller. Specifically, "determining whether to wake up the controller based on the probability of a collision detected by the detection component and the charging status detected by the charging controller" includes: if the detection component detects a collision probability greater than a first preset probability, and the charging controller detects the vehicle is charging, then the detection component and the charging controller cooperate to wake up the controller. Specifically, if the detection component detects a collision probability greater than the first preset probability, it sends data to the controller via the CAN bus; if the charging controller detects the vehicle is charging, it also sends data to the controller via the CAN bus; then the detection component and the charging controller cooperate to wake up the controller. That is, the airbag controller can only be woken up after simultaneously receiving wake-up data from both the detection component and the charging controller. Waking up the controller allows it to be in a state of processing data and sending collision output signals at all times, enabling a rapid response and shortening the response time in the event of a collision.

[0139] "Determine whether to wake up the controller based on the probability of a collision detected by the detection component and the charging status of the vehicle detected by the charging controller" also includes: if the probability of a collision detected by the detection component is not greater than a first preset probability, and the charging controller does not detect that the vehicle is in a charging state, then there is no need to wake up the controller.

[0140] The controller determines whether to lower the trigger threshold of the controller's collision output signal based on the probability of a vehicle collision and the controller's state. Specifically, if the detection component detects a collision probability greater than a second preset probability, and the controller is in an awake state, then the controller lowers the trigger threshold of the controller's collision output signal, wherein the second preset probability is not less than a first preset probability. Lowering the trigger threshold enables the vehicle to quickly take safety measures in the event of a collision, thereby protecting personal and property safety.

[0141] When a potential collision is not detected in advance but a collision actually occurs, the necessary safety measures are determined based on the severity of the collision. If the collision severity exceeds a first preset threshold, the vehicle's charging and high-voltage power are cut off; if it exceeds a second preset threshold, warning lights are illuminated and the horn sounds; if it exceeds a third preset threshold, collision information is sent to the user or backend so the user can handle the damaged vehicle. The second and third preset thresholds can be the same as or higher than the first preset threshold. If the collision severity exceeds a fourth preset threshold, the battery airbag and passenger airbag are deployed; the fourth preset threshold is higher than the first preset threshold. That is, deploying the battery airbag and passenger airbag when the collision is severe protects the battery and the occupants in the passenger compartment. This invention lowers the trigger thresholds of the output signal by reducing the first, second, third, and fourth preset thresholds, enabling the vehicle to quickly take safety measures to protect personal and property safety upon collision. Since the probability of early collision detection is relatively high, lowering the trigger thresholds almost eliminates the possibility of misoperation.

[0142] The statement "The controller determines whether to lower the trigger threshold of the controller collision output signal based on the probability of a vehicle collision and the controller's state" also includes: if the detection component detects a collision probability that is not greater than a second preset probability, or the controller is not in a wake-up state, then there is no need for a trigger threshold for the controller collision output signal.

[0143] The vehicle also includes a collision detection system capable of collecting vehicle collision data. Specifically, the collision detection system includes a collision sensor and a central acceleration sensor. The collision sensor is communicatively connected to the airbag controller. The collision sensor is used to collect vehicle collision data. In this embodiment, the central acceleration sensor is located inside the airbag controller and can detect the vehicle's acceleration information. Although in this embodiment the central acceleration sensor is located inside the airbag controller, this is not a limitation of the invention. In other embodiments, the central acceleration sensor can also be located in other locations within the vehicle, communicating with the airbag controller via a CAN bus to transmit the detected acceleration information to the airbag controller. These modifications do not depart from the basic principles of the invention and will fall within the protection scope of the invention.

[0144] The controller can determine the degree of vehicle collision based on the collision data collected by the collision detection device and the environmental data collected by the detection components.

[0145] The controller can also determine the safety measures that need to be taken to control the vehicle based on the severity of the collision.

[0146] The vehicle includes a battery manager and a body controller. The battery manager communicates with the controller via a CAN bus, as does the body controller. The controller communicates with a networked host via a wireless signal.

[0147] "The controller can also determine the safety measures that need to be taken to control the vehicle based on the severity of the collision," including:

[0148] When the collision severity exceeds the first preset threshold, the controller sends a collision output signal (i.e., a power-off signal) to the battery manager, which then cuts off the charging and high-voltage power to the vehicle. When the collision severity exceeds the second preset threshold, the controller sends a collision output signal (i.e., a warning signal) to the body controller, which then illuminates the warning lights and sounds the horn. When the collision severity exceeds the third preset threshold, the controller sends a collision output signal to the network host, which then sends the collision information to the user or a backend system so that the user can handle the damaged vehicle. The second and third preset thresholds can be the same as or greater than the first preset threshold. When the collision severity exceeds the fourth preset threshold, the controller deploys the battery airbag and the passenger compartment airbag; the fourth preset threshold is greater than the first preset threshold. In other words, deploying the battery airbag and the passenger compartment airbag in severe collisions protects the battery and the occupants inside the vehicle. If the degree of collision is not greater than the first preset threshold, no safety measures are required. That is, if the degree of collision is low, such as a collision with a basketball or football, a collision with a car door, a minor collision with a human body, or a minor collision with a bicycle tire, the degree of collision is low and will not affect the safety of the vehicle, so no safety measures are required.

[0149] Lowering the trigger threshold for the collision output signal includes lowering the first preset threshold, the second preset threshold, the third preset threshold, and the fourth preset threshold. Specifically, if the probability of a collision is greater than the second preset probability, and the controller is in a wake-up state, then the first preset threshold, the second preset threshold, the third preset threshold, and the fourth preset threshold are lowered.

[0150] Example 3

[0151] This embodiment discloses a vehicle, specifically a pure electric vehicle or a hybrid electric vehicle, equipped with a battery that requires a charging station to charge. The vehicle can detect its surrounding environment, specifically through radar and cameras, primarily detecting the position and movement of objects in the vicinity to determine the likelihood of a collision. The vehicle specifically includes a detection component and a control device. The control device includes a processor and a storage device, the storage device being suitable for storing multiple lines of program code, which are loaded and executed by the processor to perform the vehicle charging control method as described in Embodiment 1. The vehicle's control module is integrated into the control device; this control module is specifically a collision control module. In this embodiment, the control device is specifically a central control system, which includes a collision control module, a charging control module, a battery management module, and a body control module. The central control system and the detection component are connected via a CAN bus.

[0152] The detection component can detect the environment surrounding the vehicle and determine the probability of a collision. The surrounding environment mainly refers to objects around the vehicle, especially moving objects, particularly moving vehicles such as electric vehicles, tricycles, and cars. It analyzes the distance between the objects and the vehicle, the direction of the objects' movement, and the relative speed between the objects and the vehicle to determine whether a collision will occur. If the distance between the object and the vehicle is less than a preset distance, the object is moving towards the vehicle, and the object's speed is greater than a preset speed (a speed greater than the preset speed allows the object to collide with the vehicle due to its own inertia; if the object also has a power source, the probability of a collision is even greater), then it is determined that the object is very likely to collide with the vehicle, meaning the collision probability is greater than a first preset probability.

[0153] The detection components include radar and cameras, which work together to detect the vehicle's surroundings. Specifically, the camera takes pictures and identifies objects based on image recognition. The radar detects the distance, direction of movement, and speed of objects. The radar and camera communicate with each other and analyze the data, sending the overall result—the probability of a collision—to the central control system to trigger the collision control module.

[0154] The charging control module of the central control system can specifically control whether the battery is charged, determine the battery charging data, and detect the battery status.

[0155] The detection component can detect the environment around the vehicle and determine the probability of a collision.

[0156] Based on the probability of a vehicle collision detected by the detection components and the vehicle's charging status detected by the central control system, a decision is made as to whether to activate the central control system's collision control module. This specifically includes:

[0157] If the detection component detects a collision probability greater than a first preset probability, and the central control system detects the vehicle is charging, then the detection component and the central control system work together to wake up the collision control module. Specifically, if the detection component detects a collision probability greater than the first preset probability, it sends data to the central control system via the CAN bus. If the central control system detects the vehicle is charging, then the detection component and the central control system work together to wake up the collision control module. That is, the collision control module can only be woken up after receiving wake-up data from both the detection component and the central control system. Waking up the collision control module ensures that it is always in a state of processing data and sending collision output signals, enabling a rapid response and shortening the response time in the event of a collision.

[0158] "Determining whether to wake up the collision control module of the central control system based on the probability of a collision detected by the detection component and the charging status of the vehicle detected by the central control system" also includes: if the probability of a collision detected by the detection component is not greater than a first preset probability, or if the central control system does not detect that the vehicle is in a charging state, then there is no need to wake up the collision control module.

[0159] The collision control module determines whether to lower the trigger threshold of its collision output signal based on the probability of a collision and the module's own status. Specifically, if the detection component detects a collision probability greater than a second preset probability, and the collision control module is in an active state, then the collision control module lowers the trigger threshold of its collision output signal, where the second preset probability is not less than a first preset probability. Lowering the trigger threshold allows the vehicle to quickly take safety measures in the event of a collision, protecting personal and property safety.

[0160] When a potential collision is not detected in advance but a collision actually occurs, the necessary safety measures are determined based on the severity of the collision. If the collision severity exceeds a first preset threshold, the vehicle's charging and high-voltage power are cut off; if it exceeds a second preset threshold, warning lights are illuminated and the horn sounds; if it exceeds a third preset threshold, collision information is sent to the user or backend so the user can handle the damaged vehicle. The second and third preset thresholds can be the same as or higher than the first preset threshold. If the collision severity exceeds a fourth preset threshold, the battery airbag and passenger airbag are deployed; the fourth preset threshold is higher than the first preset threshold. That is, deploying the battery airbag and passenger airbag when the collision is severe protects the battery and the occupants in the passenger compartment. This invention lowers the trigger thresholds of the output signal by reducing the first, second, third, and fourth preset thresholds, enabling the vehicle to quickly take safety measures to protect personal and property safety upon collision. Since the probability of early collision detection is relatively high, lowering the trigger thresholds almost eliminates the possibility of misoperation.

[0161] "The collision control module determines whether to lower the trigger threshold of the collision output signal based on the probability of a vehicle collision and the state of the collision control module." Specifically, this also includes: if the detection component detects a collision probability no greater than a second preset probability, and the collision control module is not in a wake-up state, then there is no need to lower the trigger threshold of the collision output signal.

[0162] The vehicle includes collision detection components, specifically a collision sensor and a central acceleration sensor, capable of detecting the vehicle's acceleration information. The central acceleration sensor can be located within the central control system. Although in this embodiment the central acceleration sensor is located within the central control system, this is not a limitation of the invention. In other embodiments, the central acceleration sensor can be located in other locations within the vehicle and communicate with the central control system via a CAN bus to transmit the detected acceleration information. These modifications do not depart from the basic principles of the invention and will fall within the scope of protection of this invention.

[0163] The collision sensor can collect data on vehicle collisions, and the collision sensor communicates with the central control system via a CAN bus.

[0164] The collision control module can determine the degree of collision of a vehicle based on the collision data collected by the collision detection device and the environmental data collected by the detection component.

[0165] The collision control module can also determine the safety measures that need to be taken to control the vehicle based on the severity of the collision.

[0166] "The collision control module can also determine the safety measures that need to be taken to control the vehicle based on the severity of the collision," including:

[0167] When the collision severity exceeds the first preset threshold, the collision control module sends a power-off signal to the battery management module, causing the battery management module to cut off the charging and high-voltage power to the vehicle. When the collision severity exceeds the second preset threshold, the collision control module sends a warning signal to the body control module, causing the body control module to illuminate the warning lights and sound the horn. When the collision severity exceeds the third preset threshold, the collision control module sends a collision output signal to the network host, which then sends the collision information to the user or backend system so that the user can handle the damaged vehicle. The second and third preset thresholds can be the same as or greater than the first preset threshold. When the collision severity exceeds the fourth preset threshold, the central control system controls the deployment of the battery airbags and the passenger compartment airbags. The fourth preset threshold is greater than the first preset threshold; lowering the trigger threshold for the collision output signal refers to lowering the fourth preset threshold. In other words, deploying the battery airbags and passenger compartment airbags in severe collisions protects the battery and the occupants in the passenger compartment. If the degree of collision is not greater than the first preset threshold, no safety measures are required. That is, if the degree of collision is low, such as a collision with a basketball or football, a collision with a car door, a minor collision with a human body, or a minor collision with a bicycle tire, the degree of collision is low and will not affect the safety of the vehicle, so no safety measures are required.

[0168] Lowering the trigger threshold for the collision output signal includes lowering the first preset threshold, the second preset threshold, the third preset threshold, and the fourth preset threshold. That is, if the probability of a collision is greater than the second preset probability, and the control module is in a wake-up state, then the first preset threshold, the second preset threshold, the third preset threshold, and the fourth preset threshold are lowered.

[0169] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
