Description

Technical Field

[0001] The present application relates to the field of automobile technology, and in particular to an electronic parking system wake-up method, device, storage medium, system and vehicle. Background Art

[0002] With the rapid development of the automobile industry, cars have become one of the indispensable means of transportation for people to travel. The number of cars has increased year by year, and more and more people own private cars. At present, most cars are equipped with an electronic parking brake (EPB), which can monitor whether the car slips after the car goes into sleep mode, and apply a clamping force to stop the car from slipping after the car slips.

[0003] However, in the prior art, if the electronic parking system keeps monitoring the car's slipping condition after the car is parked, it will seriously waste the car's power. If the electronic parking system is dormant after the car is parked, it will not be able to monitor whether the car is slipping, thus posing a safety hazard. Summary of the invention

[0004] In order to solve the above technical problems existing in the prior art, the present application provides an electronic parking system wake-up method, device, storage medium, system and vehicle.

[0005] In order to solve the above problems, the present application provides an electronic parking system wake-up method, which includes: obtaining parking status information generated by the vehicle in the parking state; wherein the electronic parking system of the vehicle is in a dormant state in the parking state; and determining whether to wake up the electronic parking system based on the parking status information. As a result, the electronic parking system of the vehicle is in a dormant state in the parking state of the vehicle, which can alleviate the risk of serious power loss caused by the long-term monitoring of whether the electronic parking system is slipping after the vehicle enters the parking state, and the parking status information can be used to determine whether to wake up the electronic parking system. When the parking status information indicates that there is no risk of the vehicle slipping, the electronic parking system continues to be in a dormant state, further alleviating the risk of serious power loss. When the parking status information indicates that the vehicle may slip, the electronic parking system can be awakened to apply a clamping force to the vehicle to prevent the vehicle from slipping. There is no need to keep the electronic parking system in a monitoring state for a long time, and the risk of accidents can be alleviated, thereby improving the safety performance of the vehicle when parking.

[0006] In some embodiments, the parking state information includes acceleration data, and the step of determining whether to wake up the electronic parking system based on the parking state information includes: comparing the acceleration data with a first acceleration threshold; if the acceleration data is greater than or equal to the first acceleration threshold, waking up the electronic parking system. Thus, the acceleration data is compared with the first acceleration threshold, and when the acceleration data is greater than or equal to the first acceleration threshold, it can be accurately characterized that the vehicle is at risk of rolling away. At this time, the electronic parking system can be awakened to apply a clamping force to the vehicle to prevent the vehicle from rolling away, thereby improving the accuracy of the vehicle rolling away detection and improving the safety performance of the vehicle when parking.

[0007] In some embodiments, after the step of comparing the acceleration data with the first acceleration threshold, the electronic parking system wake-up method further includes: if the acceleration data is less than the first acceleration threshold, the electronic parking system remains in a dormant state. Thus, when the acceleration data is less than the first acceleration threshold, it can be accurately characterized that there is no risk of the vehicle rolling away, so that the electronic parking system continues to remain in a dormant state, further alleviating the risk of serious loss of vehicle power.

[0008] In some embodiments, the vehicle controller of the vehicle is in a dormant state in the parking state, and the step of comparing the acceleration data with the first acceleration threshold includes: comparing the acceleration data with the second acceleration threshold, wherein the first acceleration threshold is greater than the second acceleration threshold; if the acceleration data is greater than or equal to the second acceleration threshold, waking up the vehicle controller; in response to the vehicle controller being in the awake state, comparing the acceleration data with the first acceleration threshold. Thus, before waking up the electronic parking system, the acceleration data is first compared with the second acceleration threshold. When the acceleration data is greater than or equal to the second acceleration threshold, it can be characterized that the vehicle may have a risk of slipping. At this time, the vehicle controller can be woken up first, and the vehicle controller can be further used to determine whether the vehicle is slipping according to the acceleration data, so that the electronic parking system can be woken up more accurately to apply a clamping force to the vehicle to prevent the vehicle from slipping, thereby improving the safety performance of the vehicle when parking.

[0009] In some embodiments, after the step of comparing the acceleration data with the second acceleration threshold, the electronic parking system wake-up method includes: if the acceleration data is less than the second acceleration threshold, the vehicle controller remains in a dormant state. Thus, when the acceleration data is less than the second acceleration threshold, it can accurately indicate that the vehicle has no risk of rolling away, and the electronic parking system and the vehicle controller can continue to remain in a dormant state, further alleviating the risk of serious loss of vehicle power.

[0010] In some embodiments, the vehicle controller of the vehicle is in a dormant state in the parking state, and the parking state information includes angular velocity data. The step of determining whether to wake up the electronic parking system based on the parking state information includes: comparing the angular velocity data with the angular velocity threshold; if the angular velocity data is greater than or equal to the angular velocity threshold, waking up the vehicle controller; in response to the vehicle controller being in the awake state, determining whether to wake up the electronic parking system. Therefore, before waking up the electronic parking system, the angular velocity data is first compared with the angular velocity threshold. When the angular velocity data is greater than or equal to the angular velocity threshold, it can be characterized that the vehicle may have a risk of slipping. At this time, the vehicle controller can be woken up first, and the vehicle controller can be used to further determine whether the vehicle is slipping, so that the electronic parking system can be more accurately woken up to apply a clamping force to the vehicle to prevent the vehicle from slipping, thereby improving the safety performance of the vehicle when parking.

[0011] In some embodiments, the vehicle controller of the vehicle is in a dormant state when the vehicle is in a parking state, and the method for waking up the electronic parking system includes: waking up the vehicle controller based on parking state information; in response to the vehicle controller being in an awake state, monitoring the parking state of the vehicle within a preset time period; if the electronic parking system is not awakened within the preset time period based on the parking state, the vehicle executes a power-off process. Thus, after the vehicle controller is awakened, if the electronic parking system still does not need to be awakened within the preset monitoring time period, it can be determined that there is no risk of the vehicle rolling away, and the vehicle can be made to execute a power-off process at this time, further alleviating the risk of serious loss of vehicle power.

[0012] In order to solve the above problems, the present application provides a parking control system, which includes an inertial sensor, a vehicle controller and an electronic parking system; the inertial sensor is used to obtain parking state information generated by the vehicle in the parking state, wherein the electronic parking system of the vehicle is in a dormant state in the parking state; the vehicle controller is used to determine whether to wake up the electronic parking system based on the parking state information. As a result, the electronic parking system of the vehicle is in a dormant state in the parking state of the vehicle, which can alleviate the risk of serious power loss caused by the electronic parking system monitoring whether the vehicle slips for a long time after the vehicle enters the parking state, and the inertial sensor can obtain parking information, which is convenient for the vehicle controller to determine whether to wake up the electronic parking system through the parking state information. When the parking state information indicates that there is no risk of the vehicle slipping, the electronic parking system continues to be in a dormant state, further alleviating the risk of serious power loss. When the parking state information indicates that the vehicle may slip, the electronic parking system can be awakened to apply a clamping force to the vehicle to stop the vehicle from slipping, without the need to keep the electronic parking system in a monitoring state for a long time, and can also alleviate the risk of accidents, thereby improving the safety performance of the vehicle when parking.

[0013] In some embodiments, the inertial sensor includes an accelerometer, and the accelerometer is used to obtain acceleration data generated by the vehicle in the parking state. The vehicle controller is used to compare the acceleration data with a first acceleration threshold, and if the acceleration data is greater than or equal to the first acceleration threshold, the electronic parking system is awakened. Thus, the acceleration data is compared with the first acceleration threshold, and when the acceleration data is greater than or equal to the first acceleration threshold, it can be accurately characterized that the vehicle is at risk of rolling. At this time, the electronic parking system can be awakened to apply a clamping force to the vehicle to prevent the vehicle from rolling, thereby improving the accuracy of the vehicle rolling detection and improving the safety performance of the vehicle when parking.

[0014] In some embodiments, the inertial sensor includes a gyroscope, which is used to obtain angular velocity data and / or angular acceleration data generated by the vehicle in the parking state, and the gyroscope responds to the angular velocity data and / or angular acceleration data to wake up the vehicle controller and / or the electronic parking system. Therefore, by obtaining the angular velocity data and / or angular acceleration data through the gyroscope, and then waking up the vehicle controller and / or the electronic parking system, the electronic parking system can be more accurately awakened to apply a clamping force to the vehicle to prevent the vehicle from slipping, thereby improving the safety performance of the vehicle when parking.

[0015] In order to solve the above problems, the present application provides a vehicle, which includes the above parking control system.

[0016] To solve the above problems, the present application provides an electronic parking system wake-up device, which includes a processor and a memory. The memory stores a computer program, and the processor is used to execute the computer program to implement the above electronic parking system wake-up method.

[0017] In order to solve the above problems, the present application provides a computer-readable storage medium on which program instructions are stored. When the program instructions are executed by a processor, the above-mentioned electronic parking system wake-up method is implemented.

[0026] The present application is further described in detail below in conjunction with the accompanying drawings and examples. It is particularly noted that the following examples are only used to illustrate the present application, but are not intended to limit the scope of the present application. Similarly, the following examples are only some embodiments of the present application rather than all embodiments, and all other embodiments obtained by those of ordinary skill in the art without making creative work are within the scope of protection of the present application.

[0027] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0028] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "install", "set", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or connected through an intermediate medium. For ordinary technicians in this field, the above-mentioned specific meanings belonging to this application can be connected according to specific circumstances.

[0029] With the rapid development of the vehicle industry, vehicles have become one of the indispensable means of transportation for people to travel. The number of vehicles has increased year by year, and more and more people own private cars. At present, most vehicles are equipped with an electronic parking brake (EPB), which can monitor whether the vehicle is slipping after the vehicle is dormant, and apply a clamping force to stop the vehicle from slipping after the vehicle slips.

[0030] The electronic parking system can integrate functions such as static switch parking control, P gear linkage parking control, power-off automatic clamping parking control, high temperature re-clamping control, rolling re-clamping control, etc., which can not only meet the driver's parking control needs under normal driving conditions, but also protect the driver from certain unknown risks, such as forgetting to park, abnormal slipping and other dangerous situations. For example, the rolling re-clamping control function mainly detects whether the wheel speed sensor pulse value has abnormal changes within a period of time after the electronic parking system completes the clamping. Once an abnormal change occurs, it is judged that the vehicle has slipped, and the re-clamping function will be activated to increase the clamping force of the left and right calipers to the maximum level to ensure safe parking of the vehicle.

[0031] In the related art, the vehicle slipping re-clamping function is mainly controlled by the electronic parking system. For example, the vehicle can still be monitored for slipping within a specific time period after the vehicle is powered off. When the slipping event occurs again after the specific time period, the electronic parking system will not be able to continue monitoring, which poses a safety hazard. If the electronic parking system is in a monitoring state for a long time after the vehicle is powered off, the controller associated with the electronic parking system will also be unable to enter a dormant state, resulting in a serious loss of battery energy in the vehicle. If a timed wake-up scheme for the electronic parking system is adopted, such as waking up the electronic parking system every hour, and the monitoring time after waking up is half an hour, it is difficult to wake up the electronic parking system at a specific frequency due to the uncertainty of the occurrence of the vehicle slipping phenomenon, which ultimately leads to the ineffectiveness of the slipping monitoring, which usually poses a major safety hazard.

[0032] In order to solve the technical problems existing in the related art, the present application provides a method for waking up an electronic parking system, see Figure 1 , Figure 1 1 is a flowchart of a method for waking up an electronic parking system according to one or more embodiments of the present application, specifically, comprising the following steps S101 to S102.

[0033] Step S101: Acquire parking state information generated when the vehicle is in a parking state, wherein the electronic parking system of the vehicle is in a dormant state when the vehicle is in the parking state.

[0034] The vehicle may include but is not limited to a fuel vehicle, a gas vehicle or a new energy vehicle, and the new energy vehicle may be a pure electric vehicle, a hybrid vehicle or an extended-range vehicle, etc. The vehicle enters the parking state after stopping driving, for example, the vehicle may enter the parking state after implementing the power-off process, and when the vehicle is in the parking state, the relevant control systems inside the vehicle may enter a dormant state, for example, the vehicle may be equipped with an electronic stability control system (Electronic Stability Control System, ESC), also known as the electronic stability program (Electronic Stability Program, ESP), vehicle stability control device (Vehicle Stability Control, VSC), vehicle stability assist device (Vehicle Stability Assist, VSA) or dynamic stability control device DSC (Dynamic Stability Control) and other systems, when the vehicle enters the parking state, the above-mentioned relevant systems in the vehicle may enter a dormant state.

[0035] The vehicle is equipped with an electronic parking system, which can apply a clamping force to prevent the vehicle from slipping. When the vehicle enters the parking state, the electronic parking system enters a dormant state. For example, after the vehicle stops and completes parking, it can continue to monitor whether the vehicle slips. If the vehicle is detected to be slipping within a preset time period, the electronic parking system applies a clamping force to prevent the vehicle from slipping. If the vehicle is still not detected to be slipping within the preset time period, the vehicle executes the power-off process.

[0036] After the vehicle is parked and enters the parking state, the vehicle is usually in a stationary state, and the parking state information can be used to characterize the risk state of the vehicle in abnormal slipping, such as determining that the vehicle is at risk of slipping based on the parking state information, or determining that the vehicle is not at risk of slipping based on the parking state information. The parking state information can be obtained through an inertial sensor, and the inertial sensor can be integrated in the vehicle, for example, the inertial sensor can be integrated in the vehicle controller. The parking state information generated by the vehicle in the parking state is detected by the inertial sensor, for example, the inertial sensor can be integrated with an accelerometer and a gyroscope at the same time, and the acceleration in each direction is detected by the accelerometer, or the rotational angular velocity is detected by the gyroscope, so that the parking state information can be determined based on the acceleration and / or rotational angular velocity detected by the sensor.

[0037] Step S102: Determine whether to wake up the electronic parking system based on the parking state information.

[0038] If it is determined based on the parking status information that the vehicle does not have the risk of rolling away, there is no need to wake up the electronic parking system, so that the electronic parking system continues to remain in a dormant state. If it is determined based on the parking status information that the vehicle has the risk of rolling away, the electronic parking system can be woken up, and a clamping force can be applied by the electronic parking system to prevent the vehicle from rolling away. For example, an inertial sensor can be integrated into a vehicle controller. When the inertial sensor detects the parking status information, the vehicle controller can be woken up first, and the vehicle controller determines whether to wake up the electronic parking system.

[0039] Through the above implementation, the electronic parking system of the vehicle is in a dormant state when the vehicle is in the parking state, which can alleviate the risk of serious power loss caused by the electronic parking system monitoring the vehicle for a long time after the vehicle enters the parking state, and can determine whether to wake up the electronic parking system through the parking state information. When the parking state information indicates that the vehicle has no risk of slipping, the electronic parking system continues to be in a dormant state, further alleviating the risk of serious power loss. When the parking state information indicates that the vehicle may have a risk of slipping, the electronic parking system can be awakened to apply a clamping force to the vehicle to prevent the vehicle from slipping. There is no need to keep the electronic parking system in a monitoring state for a long time, and the risk of accidents can be alleviated, thereby improving the safety performance of the vehicle when parking.

[0040] See also Figure 2 , Figure 2 yes Figure 1 Specifically, it includes the following steps S201 to S202.

[0041] Step S201: Compare the acceleration data with a first acceleration threshold.

[0042] The parking state information includes acceleration data, which can be obtained through an inertial sensor. The inertial sensor is integrated in the vehicle. The inertial sensor may include an accelerometer, and the acceleration data of the vehicle in the parking state is monitored in real time through the accelerometer. The acceleration data can be generated by the acceleration data of the whole vehicle. For example, the inertial sensor is integrated in the chassis of the vehicle. When the whole vehicle shakes, the inertial sensor detects the acceleration data; or the acceleration data can also be the acceleration data of a certain part of the vehicle, such as detecting the acceleration data of vehicle components such as wheels, gearboxes, and axles. The first acceleration threshold can be set according to actual conditions and is not limited here. After obtaining the acceleration data, the acceleration data can be compared with the first acceleration threshold, so as to determine whether to wake up the electronic parking system based on the result of the comparison between the acceleration data and the first acceleration threshold.

[0043] Step S202: If the acceleration data is greater than or equal to the first acceleration threshold, the electronic parking system is awakened.

[0044] The first acceleration threshold can be used to characterize the risk state of abnormal vehicle slipping. If the acceleration data obtained according to the comparison result is greater than the first acceleration threshold, it is determined that the vehicle is at risk of slipping. At this time, the electronic parking system can be awakened to apply a clamping force to prevent the vehicle from slipping. Therefore, by comparing the acceleration data with the first acceleration threshold, it can be more accurately characterized that the vehicle is at risk of slipping. At this time, the electronic parking system can be awakened to apply a clamping force to the vehicle to prevent the vehicle from slipping, thereby improving the accuracy of the vehicle slipping detection and improving the safety performance of the vehicle when parking.

[0045] Furthermore, after the step of comparing the acceleration data with the first acceleration threshold (step S201), the electronic parking system wake-up method further includes: if the acceleration data is less than the first acceleration threshold, the electronic parking system remains in a dormant state. If the acceleration data is less than the first acceleration threshold according to the comparison result, it is determined that the vehicle does not have a risk of rolling away, and the electronic parking system continues to be in a dormant state. This can more accurately characterize that the vehicle does not have a risk of rolling away, so that the electronic parking system continues to be in a dormant state, further alleviating the risk of serious power loss of the vehicle.

[0046] See also Figure 3 , Figure 3 yes Figure 2 Specifically, it includes the following steps S301 to S303.

[0047] Step S301: Compare the acceleration data with a second acceleration threshold, wherein the first acceleration threshold is greater than the second acceleration threshold.

[0048] The vehicle controller of the vehicle is in a dormant state when the vehicle is parked. The vehicle controller may include but is not limited to the vehicle controller of the vehicle or other controllers that can perform operations such as waking up or sleeping the electronic parking system. The second acceleration threshold can be set according to actual conditions and is not limited here. The first acceleration threshold is greater than the second acceleration threshold. After obtaining the acceleration data, the acceleration data and the second acceleration threshold can be compared first, so as to determine whether to wake up the vehicle controller based on the result of the comparison between the acceleration data and the second acceleration threshold.

[0049] Step S302: If the acceleration data is greater than or equal to the second acceleration threshold, the vehicle controller is awakened.

[0050] The second acceleration threshold can be used to characterize the risk state that the vehicle may be in an abnormal slipping state. If the acceleration data obtained according to the comparison result is greater than the second acceleration threshold, it is determined that the vehicle may be in a risk of slipping. At this time, the vehicle controller can be awakened to further determine whether the vehicle is in an abnormal slipping risk through the vehicle controller. Specifically, the inertial sensor can be electrically connected to the power control module of the vehicle controller. When the inertial sensor detects a change in the acceleration data, it can first determine whether the acceleration data is greater than the second acceleration threshold. If the acceleration data is greater than the second acceleration threshold, the inertial sensor wakes up the power control module of the vehicle controller, and then wakes up the vehicle controller.

[0051] Step S303: In response to the vehicle controller being in the awake state, comparing the acceleration data with a first acceleration threshold.

[0052] When the vehicle controller is awakened, the vehicle controller can read the acceleration data collected by the inertial sensor and compare the acceleration data with the first acceleration threshold. If the acceleration data is greater than the first acceleration threshold according to the comparison result, it is determined that the vehicle is at risk of slipping. At this time, the electronic parking system can be awakened, and the electronic parking system applies a clamping force to prevent the vehicle from slipping. Therefore, the vehicle controller is awakened before the electronic parking system is awakened, and the vehicle controller further determines whether the vehicle is slipping according to the acceleration data, so that the electronic parking system can be awakened more accurately to apply a clamping force to the vehicle to prevent the vehicle from slipping, thereby improving the safety performance of the vehicle when parking.

[0053] Furthermore, after the step of comparing the acceleration data with the second acceleration threshold (step S301), the electronic parking system wake-up method includes: if the acceleration data is less than the second acceleration threshold, the vehicle controller remains in a dormant state. If the acceleration data is less than the second acceleration threshold according to the comparison result, it is determined that the vehicle does not have a risk of rolling away, and the vehicle controller and the electronic parking system continue to be in a dormant state. This can more accurately characterize that the vehicle has no risk of rolling away, and the electronic parking system and the vehicle controller can continue to be in a dormant state, further alleviating the risk of serious loss of vehicle power.

[0054] Furthermore, the vehicle controller of the vehicle is in a dormant state in the parking state, and the step of determining whether to wake up the electronic parking system based on the parking state information (step S102) includes: comparing the angular velocity data with the angular velocity threshold; if the angular velocity data is greater than or equal to the angular velocity threshold, waking up the vehicle controller; in response to the vehicle controller being in the awake state, determining whether to wake up the electronic parking system.

[0055] The parking state information includes angular velocity data, which can be obtained through an inertial sensor. The inertial sensor is integrated in the vehicle. The inertial sensor may include a gyroscope, and the angular velocity data of the vehicle in the parking state is monitored in real time through the gyroscope. The angular velocity data may be the angular velocity data of the entire vehicle. For example, the inertial sensor is integrated in the chassis of the vehicle. When the entire vehicle shakes, the inertial sensor detects the generation of angular velocity data; or the angular velocity data may also be the angular velocity data of a certain part of the vehicle, such as detecting the angular velocity data of vehicle components such as wheels, gearboxes, and axles. The angular velocity threshold can be set according to actual conditions and is not limited here. After obtaining the angular velocity data, the angular velocity data and the angular velocity threshold can be compared. The angular velocity data can be used to characterize the risk state that the vehicle may have abnormal slipping. If the angular velocity data obtained according to the comparison result is greater than the angular velocity threshold, it is determined that the vehicle may have the risk of slipping. At this time, the vehicle controller can be awakened to further determine whether the vehicle has the risk of abnormal slipping through the vehicle controller. In some other embodiments, the parking state information may further include angular acceleration data. By comparing the angular acceleration data with an angular acceleration threshold, when the angular acceleration data is greater than the angular acceleration threshold, the vehicle controller is awakened.

[0056] Furthermore, the inertial sensor may also include an accelerometer, which may collect acceleration data. After the vehicle controller is awakened, the vehicle controller may read the acceleration data collected by the inertial sensor and compare the acceleration data with a first acceleration threshold. If the acceleration data is greater than the first acceleration threshold according to the comparison result, it is determined that the vehicle is at risk of slipping. At this time, the electronic parking system may be awakened, and a clamping force may be applied by the electronic parking system to prevent the vehicle from slipping. Therefore, before waking up the electronic parking system, the angular velocity data is first compared with the angular velocity threshold. When the angular velocity data is greater than or equal to the angular velocity threshold, the vehicle controller may be awakened first, and the vehicle controller may be further determined to determine whether the vehicle is slipping, thereby more accurately waking up the electronic parking system to apply a clamping force to the vehicle to prevent the vehicle from slipping, thereby improving the safety performance of the vehicle when parking.

[0057] The parking status information may further include angular velocity data and acceleration data. When the acceleration data is greater than the second acceleration threshold and the angular velocity data is greater than the angular velocity threshold, the vehicle controller is awakened.

[0058] In some embodiments, the vehicle controller of the vehicle is in a dormant state when in a parking state, and the electronic parking system wake-up method includes: waking up the vehicle controller based on parking state information; in response to the vehicle controller being in an awake state, monitoring the parking state of the vehicle within a preset time period; if the electronic parking system is not woken up within the preset time period based on the parking state, the vehicle executes a power-off process.

[0059] The method step may be after the step of obtaining the parking state information generated by the vehicle in the parking state, when the parking state information indicates that the vehicle may have the risk of abnormal slipping, the vehicle controller is awakened. For example, the parking state information includes angular velocity data and / or acceleration data, and when the acceleration data is greater than the second acceleration threshold and / or the angular velocity data is greater than the angular velocity threshold, the vehicle controller is awakened. After the vehicle controller is awakened, the parking state of the vehicle can be monitored within a preset time period, wherein the preset time period can be set according to actual conditions and is not limited here. The parking state can be characterized by the parking state information, that is, the parking state is used to monitor whether the vehicle has the risk of slipping within the preset time period. If there is a risk of slipping, the electronic parking system is awakened to apply a clamping force to prevent the vehicle from slipping. If there is no risk of slipping, the electronic parking system continues to be in a dormant state, that is, there is no need to wake up the electronic parking system within the preset time period, and the vehicle can enter the power-off process. Therefore, after the vehicle controller is awakened, if there is still no need to wake up the electronic parking system within the preset monitoring time period, it can be determined that there is no risk of the vehicle rolling away. At this time, the vehicle can execute the power-off process to further alleviate the risk of serious vehicle power loss.

[0060] In summary, the electronic parking system of the vehicle is in a dormant state when the vehicle is parked, which can alleviate the risk of serious power loss caused by the long-term monitoring of whether the vehicle slips after the vehicle enters the parking state, and can determine whether to wake up the electronic parking system through the parking state information. When the parking state information indicates that the vehicle has no risk of slipping, the electronic parking system continues to be in a dormant state, further alleviating the risk of serious power loss. When the parking state information indicates that the vehicle may slip, the electronic parking system can be awakened to apply clamping force to the vehicle to prevent the vehicle from slipping. There is no need to keep the electronic parking system in a monitoring state for a long time, and the risk of accidents can be alleviated, thereby improving the safety performance of the vehicle when parking.

[0061] In order to solve the technical problems existing in the related technology, the present application also provides a parking control system, see Figure 4 , Figure 4 It is a schematic block diagram of the structure of a parking control system according to one or more embodiments of the present application.

[0062] The parking control system 400 includes an inertial sensor 410, a vehicle controller 420, and an electronic parking system 430. The inertial sensor 410 is used to obtain parking state information generated by the vehicle in a parking state, wherein the electronic parking system 430 of the vehicle is in a dormant state in the parking state; the vehicle controller 420 is used to determine whether to wake up the electronic parking system 430 based on the parking state information.

[0063] The vehicle controller 420 may include but is not limited to the vehicle controller of the vehicle or other controllers that can perform operations such as waking up or sleeping the electronic parking system 430. The inertial sensor 410 may be electrically connected to the power control module of the vehicle controller 420. The inertial sensor may be used to collect parking state information. The inertial sensor may wake up the power control module of the vehicle controller 420 according to the parking state information, and then wake up the vehicle controller 420, so that the vehicle controller 420 can determine whether to wake up the electronic parking system 430 based on the parking state information, and apply a clamping force through the electronic parking system 430 to prevent the vehicle from slipping.

[0064] The parking control system 400 can be used to execute the electronic parking system wake-up method of any of the above embodiments, which will not be described in detail here.

[0065] Thus, the electronic parking system 430 of the vehicle is in a dormant state when the vehicle is in the parking state, which can alleviate the risk of serious power loss caused by the electronic parking system 430 monitoring whether the vehicle is slipping for a long time after the vehicle enters the parking state, and the inertial sensor 410 can obtain the parking state information, so that the vehicle controller 420 can determine whether to wake up the electronic parking system 430 through the parking state information. When the parking state information indicates that the vehicle has no risk of slipping, the electronic parking system 430 continues to be in a dormant state, further alleviating the risk of serious power loss. When the parking state information indicates that the vehicle may slip, the electronic parking system 430 can be awakened to apply a clamping force to the vehicle to prevent the vehicle from slipping. There is no need to keep the electronic parking system 430 in a monitoring state for a long time, and the risk of accidents can be alleviated, thereby improving the safety performance of the vehicle when parking.

[0066] Furthermore, the inertial sensor 410 includes an accelerometer, which is used to obtain acceleration data generated by the vehicle in the parking state. The vehicle controller 420 is used to compare the acceleration data with the first acceleration threshold value, and if the acceleration data is greater than or equal to the first acceleration threshold value, the electronic parking system 430 is awakened. If the acceleration data is less than the first acceleration threshold value, the electronic parking system 430 remains in a dormant state. The acceleration data can be the acceleration data of the entire vehicle. For example, the inertial sensor 410 is integrated in the vehicle chassis. When the entire vehicle shakes, the inertial sensor 410 detects the acceleration data; or the acceleration data can also be the acceleration data of a certain part of the vehicle, such as detecting the acceleration data of vehicle components such as wheels, gearboxes, and axles. Therefore, the acceleration data is compared with the first acceleration threshold. When the acceleration data is greater than or equal to the first acceleration threshold, it can be accurately characterized that there is a risk of the vehicle slipping. At this time, the electronic parking system 430 can be awakened to apply a clamping force to the vehicle to prevent the vehicle from slipping, thereby improving the accuracy of the vehicle slipping detection and improving the safety performance of the vehicle when parking.

[0067] Among them, the vehicle controller 420 is in a dormant state in the parking state. If the acceleration data is greater than the second acceleration threshold, the vehicle controller 420 is awakened, wherein the first acceleration threshold is greater than the second acceleration threshold. If the acceleration data is less than the second acceleration threshold, the vehicle controller 420 remains in a dormant state. Therefore, before waking up the electronic parking system 430, the acceleration data is first compared with the second acceleration threshold. When the acceleration data is greater than or equal to the second acceleration threshold, it can be characterized that the vehicle may have a risk of slipping. At this time, the vehicle controller 420 can be awakened first, and the vehicle controller 420 can further determine whether the vehicle is slipping according to the acceleration data, so that the electronic parking system 430 can be awakened more accurately to apply clamping force to the vehicle to prevent the vehicle from slipping, thereby improving the safety performance of the vehicle when parking.

[0068] Optionally, the inertial sensor 410 includes a gyroscope, which is used to obtain angular velocity data and / or angular acceleration data generated by the vehicle in the parking state, and the gyroscope responds to the angular velocity data and / or angular acceleration data to wake up the vehicle controller 420 and / or the electronic parking system 430. The angular velocity data and / or angular acceleration data may be the angular velocity data and / or angular acceleration data of the entire vehicle, for example, the inertial sensor 410 is integrated in the vehicle chassis, and when the entire vehicle shakes, the inertial sensor 410 detects the generation of angular velocity data and / or angular acceleration data; or the angular velocity data and / or angular acceleration data may also be the angular velocity data and / or angular acceleration data of a certain part of the vehicle, for example, the angular velocity data and / or angular acceleration data of vehicle components such as wheels, gearboxes, and axles are detected. After detecting the angular velocity data generated in the parking state, the angular velocity data can be compared with the angular velocity threshold; if the angular velocity data is greater than or equal to the angular velocity threshold, the vehicle controller is awakened; in response to the vehicle controller being in the awakened state, it is determined whether to wake up the electronic parking system. After detecting the angular acceleration data generated in the parking state, the angular acceleration data can be compared with the angular acceleration threshold; if the angular acceleration data is greater than or equal to the angular acceleration threshold, the vehicle controller is awakened; in response to the vehicle controller being in the awakened state, it is determined whether to wake up the electronic parking system. Thus, by acquiring angular velocity data and / or angular acceleration data through the gyroscope, and then waking up the vehicle controller 420 and / or the electronic parking system 430, the electronic parking system 430 can be more accurately awakened to apply clamping force to the vehicle to prevent the vehicle from slipping, thereby improving the safety performance of the vehicle when parking.

[0069] The vehicle controller 420 can also monitor the parking state of the vehicle within a preset time period; if the electronic parking system 430 is not awakened within the preset time period based on the parking state, the vehicle executes the power-off process. Therefore, after the vehicle controller 420 is awakened, if the electronic parking system 430 still does not need to be awakened within the preset monitoring time period, it can be determined that there is no risk of the vehicle rolling away, and the vehicle can be put into the parking state at this time, further alleviating the risk of serious loss of vehicle power.
