Description

Technical Field

[0001] The present invention relates to the field of vehicle technology, and in particular to a method, device, equipment and storage medium for automatically releasing a vehicle from parking. Background Art

[0002] In recent years, with the continuous development of social economy, the number of cars has continued to increase. Compared with public transportation, cars can go directly from the departure point to the destination, saving waiting and transfer time, improving travel efficiency, and providing convenience and comfort for people's life and work.

[0003] At present, with the popularization of electronic parking function, more and more cars are equipped with electronic parking calipers. Cars equipped with electronic parking calipers can clamp and release the calipers through electronic control. According to the use scenarios of the vehicles, there are many situations in which the parking is automatically released according to the driving environment without the driver operating the clamping and releasing switch of the electronic parking caliper. For example, when the driver controls the gear to change from P gear to other gears, if the vehicle determines that the driving environment is safe, it will automatically control the parking caliper to release the clamping force, and the vehicle can drive directly when the driver steps on the accelerator next; or the current gear of the vehicle is D gear or R gear, and the electronic parking caliper is in a clamped state at this time. If the driver steps on the accelerator at this time and plans to start the vehicle, then if the driving environment is safe at this time, the system will control the parking caliper to be released directly, and the vehicle can start directly without the driver operating the parking function switch; the above two scenarios save the driver's operation and improve the convenience of vehicle use.

[0004] However, during the above operation, the clamping force of the electronic parking caliper is released by controlling the motor so that the mechanical mechanism connected to the motor retreats from the state of pushing the friction plate and the brake disc to the state of no clamping force between the friction plate and the brake disc. Because the mechanical hard connection connected to the motor is directly controlled, and the vehicle may be parked on a slope at this time, when the driver steps on the accelerator to drive the vehicle, in order to ensure that the vehicle does not slip, and the driving force and parking brake force cannot be stuck, it is necessary to calibrate and match the slope of the motor parking brake force release and the rate of increase of the driving torque at this time, so as to avoid starting stuck or vehicle slipping. However, due to the mechanical hard connection between the motor and the friction plate and the randomness of the slope where the vehicle is parked, it is difficult to ensure a smooth start, and the practicality is not good.

[0082] In recent years, with the continuous development of social economy, the number of cars has continued to increase. Compared with public transportation, cars can go directly from the departure point to the destination, saving waiting and transfer time, improving travel efficiency, and providing convenience and comfort for people's life and work.

[0083] At present, with the popularization of electronic parking function, more and more cars are equipped with electronic parking calipers. Cars equipped with electronic parking calipers can clamp and release the calipers through electronic control. According to the use scenarios of the vehicles, there are many situations in which the parking is automatically released according to the driving environment without the driver operating the clamping and releasing switch of the electronic parking caliper. For example, when the driver controls the gear to change from P gear to other gears, if the vehicle determines that the driving environment is safe, it will automatically control the parking caliper to release the clamping force, and the vehicle can drive directly when the driver steps on the accelerator next; or the current gear of the vehicle is D gear or R gear, and the electronic parking caliper is in a clamped state at this time. If the driver steps on the accelerator at this time and plans to start the vehicle, then if the driving environment is safe at this time, the system will control the parking caliper to be released directly, and the vehicle can start directly without the driver operating the parking function switch; the above two scenarios save the driver's operation and improve the convenience of vehicle use.

[0084] However, during the above operation, the clamping force of the electronic parking caliper is released by controlling the motor so that the mechanical mechanism connected to the motor retreats from the state of pushing the friction plate and the brake disc to the state of no clamping force between the friction plate and the brake disc. Because the mechanical hard connection connected to the motor is directly controlled, and the vehicle may be parked on a slope at this time, when the driver steps on the accelerator to drive the vehicle, in order to ensure that the vehicle does not slip, and the driving force and parking brake force cannot be stuck, it is necessary to calibrate and match the slope of the motor parking brake force release and the rate of increase of the driving torque at this time, so as to avoid starting stuck or vehicle slipping. However, due to the mechanical hard connection between the motor and the friction plate and the randomness of the slope where the vehicle is parked, it is difficult to ensure a smooth start, and the practicality is not good.

[0085] In view of this, an embodiment of the present application provides an automatic release method, device, equipment and storage medium for parking a vehicle. When a target vehicle is on a slope, the method detects whether the driver of the target vehicle is in position; if it is determined that the driver is in position, detects whether the brake pedal of the target vehicle is pressed; if it is determined that the brake pedal is pressed, detects the current slope signal of the target vehicle, and determines the corresponding target braking force and target driving force according to the slope signal; wherein the target braking force is the minimum braking force corresponding to the target vehicle when the target vehicle does not slip on the slope, and the target driving force is the minimum driving force for the target vehicle to start upward movement on the slope; if it is determined that the gear position of the target vehicle is switched to the driving gear, releases the current electronic parking caliper and adjusts the hydraulic braking force to the target braking force; when it is detected that the accelerator pedal of the target vehicle is pressed, the hydraulic braking force is released synchronously according to the stroke of the accelerator pedal until the first driving force corresponding to the stroke of the accelerator pedal reaches the target driving force. This method automatically releases the electronic parking caliper based on the driver's operation after identifying the driver's starting demand, and ensures that the vehicle does not roll down the slope through compensation of hydraulic braking force. When the driver continues to increase the throttle opening to drive the vehicle, the method controls the coordination of the hydraulic braking force and the increasing driving force to ensure the smoothness of the vehicle's starting power increase, improve the safety of the vehicle's starting, enhance the driving experience, and improve practicality.

[0086] Please refer to Figure 1 , Figure 1 A schematic diagram of the implementation environment of an automatic release method for parking a vehicle provided in an embodiment of the present application is shown. In this implementation environment, the main hardware and software entities involved include a terminal device 110, a target vehicle 120, and a cloud server 130, wherein a communication connection can be established between the terminal device 110, the target vehicle 120, and the cloud server 130. The automatic release method for parking a vehicle provided in an embodiment of the present application can be implemented locally in the target vehicle 120, or can be executed based on data interaction between the terminal device 110 and the target vehicle 120, or between the target vehicle 120 and the cloud server 130.

[0087] Among them, the terminal device 110 of the above embodiment may include a mobile phone, a computer, a smart wearable device, a PDA device, an intelligent voice interaction device, a vehicle terminal, etc., but is not limited thereto.

[0088] The cloud server 130 can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers. It can also be a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN (Content Delivery Network), as well as big data and artificial intelligence platforms.

[0089] The terminal device 110, the target vehicle 120 and the cloud server 130 may establish a communication connection through a wireless network or a wired network. The wireless network or wired network uses standard communication technology and / or protocols, and the network may be set to the Internet or any other network, such as but not limited to a local area network (LAN), a metropolitan area network (MAN), a wide area network (WAN), a mobile, wired or wireless network, a private network or any combination of a virtual private network.

[0090] Of course, it is understandable that Figure 1 The implementation environment in the embodiment of the present application is only some optional application scenarios of the automatic release method of the vehicle parking provided in the embodiment of the present application, and the actual application is not fixed to Figure 1 The hardware and software environment shown.

[0091] Below, in combination with the introduction of the aforementioned implementation environment, an automatic release method for parking a vehicle provided in an embodiment of the present application is introduced and illustrated.

[0092] Please refer to Figure 2 , Figure 2 is a schematic diagram of an automatic release method for parking a vehicle provided in an embodiment of the present application, and the automatic release method for parking a vehicle includes but is not limited to:

[0093] Step 210: When the target vehicle is on a ramp, detecting whether the driver of the target vehicle is in place;

[0094] Step 220: If it is determined that the driver is in place, detect whether the brake pedal of the target vehicle is pressed;

[0095] Step 230: If it is determined that the brake pedal is depressed, detect the current slope signal of the target vehicle, and determine the corresponding target braking force and target driving force according to the slope signal; wherein the target braking force is the minimum braking force corresponding to the target vehicle when it does not slip on the slope, and the target driving force is the minimum driving force for the target vehicle to start moving upward on the slope;

[0096] Step 240: If it is determined that the gear position of the target vehicle is switched to the driving gear position, release the current electronic parking caliper and adjust the hydraulic braking force to the target braking force;

[0097] Step 250: When it is detected that the accelerator pedal of the target vehicle is depressed, the hydraulic braking force is synchronously released according to the stroke of the accelerator pedal until the first driving force corresponding to the stroke of the accelerator pedal reaches the target driving force.

[0098] In an embodiment of the present application, a method for automatically releasing a parked vehicle is provided. The method automatically releases an electronic parking caliper after identifying the driver's starting demand based on the driver's operation, and ensures that the vehicle does not roll down a slope by compensating the hydraulic braking force. When the driver continues to increase the throttle opening to drive the vehicle, the hydraulic braking force is controlled to coordinate with the increasing driving force to ensure the smoothness of the vehicle's starting power increase, improve the safety of the vehicle's starting, enhance the driving experience, and improve practicality.

[0099] Specifically, in the embodiment of the present application, the target vehicle refers to a vehicle equipped with an automatic release function for parking the vehicle, which can be any type of vehicle, and the present application does not limit this. The method in the embodiment of the present application can be applied to the scene where the target vehicle is parked on a slope. When executing the method in the embodiment of the present application, it can be detected whether the target vehicle is on a slope first. For example, in some embodiments, the present application can determine the body posture of the target vehicle by means of a sensor, so as to determine whether it is on a slope. For example, an inertial measurement unit, a wheel speed sensor and a pressure sensor are generally installed on the target vehicle. The inertial measurement unit is a commonly used sensor that can measure the posture and acceleration of the vehicle, usually including a three-axis accelerometer and a three-axis gyroscope, and can provide the vehicle's tilt angle information in real time. The wheel speed sensor can monitor the rotation speed of the wheel, and judge whether the vehicle is on a slope by comparing the speed difference between the front and rear wheels: on a flat road, the speed of the front and rear wheels is basically the same, and on a slope, due to the effect of gravity, the load distribution of the front and rear wheels is different, which may cause a speed difference. Therefore, by monitoring the difference in the front and rear wheel speeds, it can be inferred whether the vehicle is on a slope. A pressure sensor is installed in the suspension system of the vehicle, and the pressure sensor can detect the vertical load on each wheel. On a ramp, due to the effect of gravity, the loads of the front and rear wheels will be different. By comparing the load differences of each wheel, it is possible to determine whether the vehicle is on a ramp. Therefore, in the embodiment of the present application, the detection data of the inertial measurement unit, wheel speed sensor or pressure sensor of the target vehicle can be obtained, and according to these detection data, it is possible to determine whether the target vehicle is on a ramp. The detection data here can be of one sensor or of multiple sensors. When multiple sensors are used, it can be determined that the target vehicle is on a ramp only when each sensor determines that the target vehicle is on a ramp, or it can be determined that the target vehicle is on a ramp only when more than half of the sensors determine that the target vehicle is on a ramp, and the application does not limit this. In some embodiments, the position information of the target vehicle can also be obtained by a global positioning system (GPS), and then it is determined whether the target vehicle is on a ramp based on the position information.

[0100] In the embodiment of the present application, when the target vehicle is on a ramp, it is possible to detect whether the driver of the target vehicle is in place, that is, whether there is a driver ready to drive in the driving position of the current target vehicle. If the driver is in place, it is possible to further detect whether the brake pedal of the current target vehicle is stepped on. If the brake pedal is stepped on, it means that the current target vehicle is likely to start from the parked position. At this time, the current slope signal of the target vehicle can be detected, for example, the longitudinal acceleration of the target vehicle can be detected, and then the current slope signal of the target vehicle can be determined based on the longitudinal acceleration. The slope signal here refers to the inclination angle of the ramp where the target vehicle is located. In the embodiment of the present application, its specific size is not limited.

[0101] After the slope signal is detected, the target braking force and target driving force corresponding to the current target vehicle can be determined according to the slope signal, where the target braking force is the minimum braking force corresponding to the target vehicle when it does not slip on the ramp, and the target driving force is the minimum driving force for the target vehicle to start the upward movement on the ramp. According to the target braking force, it is convenient to control the braking force when automatically parking, and according to the target driving force, it can be judged whether the current driver controls the target vehicle to move forward. In the embodiment of the present application, it is further monitored whether the driver of the target vehicle has a shift operation, that is, the gear of the target vehicle is switched from the parking gear to the driving gear (such as D gear or R gear), if so, the current electronic parking caliper is released, and then the hydraulic braking force is adjusted to the target braking force. In this way, the electronic parking caliper can be released in advance, and the hydraulic braking force and the driving force controlled by the driver can be coordinated later to achieve a smooth start of the target vehicle.

[0102] In an embodiment of the present application, the working condition of the accelerator pedal of the target vehicle can be detected. When it is determined that the accelerator pedal is stepped on, the hydraulic braking force can be released synchronously according to the stroke of the accelerator pedal. The purpose of synchronously releasing the hydraulic braking force here is to balance the driving force and braking force of the vehicle to prevent the wheels from slipping or the vehicle from sliding backward. Specifically, in an embodiment of the present application, the stroke of the accelerator pedal can be detected at all times to determine the first driving force corresponding to it, and then the hydraulic braking force can be gradually reduced according to the increase of the first driving force. The hydraulic braking force reduced in this process matches the increased driving force, ensuring that the vehicle will not stagnate due to excessive braking force, nor will it slide backward due to insufficient braking force. Until the first driving force corresponding to the stroke of the accelerator pedal reaches the target driving force, the hydraulic braking force is released, and the target vehicle can just start to go up on the slope, thereby achieving a smooth and smooth slope start.

[0103] It can be understood that the automatic release method for vehicle parking provided in the embodiment of the present application automatically releases the electronic parking caliper after identifying the driver's starting demand based on the driver's operation, and ensures that the vehicle does not roll down the slope through compensation of hydraulic braking force. When the driver continues to increase the throttle opening to drive the vehicle, the hydraulic braking force is controlled to coordinate with the increasing driving force to ensure the smoothness of the vehicle's starting power increase, improve the safety of the vehicle's starting, improve the driving experience, and improve practicality.

[0104] Specifically, refer to Figure 3 In some embodiments, the detecting whether the driver of the target vehicle is present includes:

[0105] Obtain pressure detection data from a pressure sensor disposed at the driver's seat;

[0106] If the pressure detection data is greater than a first threshold, it is determined that the driver of the target vehicle is in position.

[0107] In the embodiment of the present application, when detecting whether the driver of the target vehicle is in place, in some embodiments, the pressure detection data of the pressure sensor set in the driving position can be obtained. In the embodiment of the present application, the pressure sensor can be installed under the driver's seat or inside the seat cushion to monitor whether the driver is sitting in the driving position in real time. It can work together with the data acquisition module and the central processing unit (CPU) to realize the detection of the driver's position. Specifically, in the embodiment of the present application, the data acquisition module can be connected to the pressure sensor, which is responsible for collecting pressure data and converting it into a digital signal that can be recognized by the system. The central processing unit can receive data from the data acquisition module and determine whether the driver is in place according to a preset first threshold. It can be understood that if there is no one in the current driving position, the detected pressure detection data is 0 or a smaller value; if the driver is sitting in the driving position, the detected pressure detection data will be a larger value. Therefore, in the embodiment of the present application, a threshold can be pre-set, recorded as the first threshold. If the pressure detection data is greater than the first threshold, it can be determined that the driver of the target vehicle is in place. On the contrary, if the pressure detection data is less than or equal to the first threshold, it can be determined that the driver of the target vehicle is not in place. In the embodiment of the present application, the size of the first threshold can be flexibly determined according to actual needs, and the present application does not limit this.

[0108] Specifically, refer to Figure 4 In some embodiments, the detecting whether the driver of the target vehicle is present includes:

[0109] Detecting a seat belt signal of a driver's seat of the target vehicle;

[0110] According to the seat belt signal, it is determined whether the driver of the target vehicle is in place.

[0111] In the embodiment of the present application, when detecting whether the driver of the target vehicle is in place, in some cases, the seat belt signal of the driver's seat of the target vehicle can also be detected, that is, it is determined whether the seat belt of the driver's seat of the target vehicle is used. If it is used, it means that there is a driver in the current driver's seat, and it can be determined that the driver of the target vehicle is in place. Conversely, if it is not used, it means that there is probably no driver in the current driver, and it can be determined that the driver of the target vehicle is not in place.

[0112] Specifically, refer to Figure 5 In some embodiments, the detecting whether the driver of the target vehicle is present includes:

[0113] Collecting image data of the driving position of the target vehicle;

[0114] Perform image recognition on the image data, and determine whether the driver of the target vehicle is in place based on the result of the image recognition.

[0115] In the embodiment of the present application, when detecting whether the driver of the target vehicle is in place, in some cases, image data of the driver's seat of the target vehicle can also be collected. Then, image recognition can be performed on the image data, for example, machine learning, deep learning and other algorithms can be used to detect whether there is a person in the image data. If there is, it can be determined that the driver of the target vehicle is in place. If not, it can be determined that the driver of the target vehicle is not in place.

[0116] Specifically, refer to Figure 6 In some embodiments, if it is determined that the driver is in position, detecting whether the brake pedal of the target vehicle is depressed includes:

[0117] If it is determined that the driver is in place, detecting whether the doors of the target vehicle are all closed;

[0118] If it is determined that all doors of the target vehicle are closed, it is detected whether the brake pedal of the target vehicle is stepped on.

[0119] In the embodiment of the present application, after determining that the driver is in position, when the automatic release function of the vehicle parking is performed, in order to ensure the safety of vehicle driving, it can be detected whether the doors of the target vehicle are completely closed. If so, the subsequent detection task is further performed, that is, whether the brake pedal of the target vehicle is stepped on. If it is found that the door is not completely closed, the driver can be reminded to operate, thereby improving the safety of vehicle application.

[0120] Specifically, refer to Figure 7 In some embodiments, adjusting the hydraulic braking force to the target braking force includes:

[0121] detecting a first braking force corresponding to a current stroke of the brake pedal;

[0122] If the first braking force is less than the target braking force, the current hydraulic braking force is increased to the target braking force; or, if the first braking force is greater than the target braking force, the current hydraulic braking force is reduced to the target braking force.

[0123] In the embodiment of the present application, when adjusting the hydraulic braking force to the target braking force, the first braking force corresponding to the current brake pedal stroke can be detected first. If the first braking force is small and smaller than the target braking force, the current hydraulic braking force can be increased to the target braking force; on the contrary, if the first braking force is large and larger than the target braking force, the current hydraulic braking force can be reduced to the target braking force.

[0124] Specifically, in some embodiments, the method further includes:

[0125] If it is determined that the brake pedal is not depressed, detecting whether the current electronic parking caliper is clamped;

[0126] If it is determined that the electronic parking caliper is clamped and the gear position of the target vehicle is the forward gear position, the current slope signal of the target vehicle is detected, and the corresponding target braking force and target driving force are determined according to the slope signal; wherein the target braking force is the minimum braking force corresponding to the target vehicle when it does not slip on the slope, and the target driving force is the minimum driving force for the target vehicle to start moving upward on the slope;

[0127] Detecting whether the accelerator pedal of the target vehicle is depressed;

[0128] If it is determined that the accelerator pedal of the target vehicle is depressed, and the first driving force corresponding to the stroke of the accelerator pedal does not reach the target driving force, releasing the current electronic parking caliper and adjusting the hydraulic braking force to the target braking force;

[0129] The hydraulic braking force is synchronously released according to the stroke of the accelerator pedal until the first driving force corresponding to the stroke of the accelerator pedal reaches the target driving force.

[0130] In the embodiment of the present application, if the driver does not step on the brake pedal, but the electronic parking caliper is clamped at this time, it can be further determined whether the gear position of the target vehicle is the forward gear position. If so, the electronic parking caliper can also be released according to the throttle situation. Specifically, in the embodiment of the present application, the slope signal of the current target vehicle can be detected to determine the corresponding target braking force and target driving force, which have the same meanings as in the aforementioned embodiment and are not repeated here. Then, it can be detected whether the throttle of the target vehicle is stepped on. If so, it can continue to determine whether the first driving force corresponding to the stroke of the throttle pedal reaches the target driving force. If it reaches, the current electronic parking caliper can be directly released, and the vehicle will move forward directly at this time. If the target driving force is not reached, the current electronic parking caliper can be released, and the hydraulic braking force can be adjusted to the target braking force, and then the hydraulic braking force can be released synchronously according to the stroke of the throttle pedal until the first driving force corresponding to the stroke of the throttle pedal reaches the target driving force. At this time, the hydraulic braking force is released, and the target vehicle can just start to go up on the slope, thereby achieving a smooth and smooth slope start.

[0131] Specifically, in some embodiments, the method further includes:

[0132] If it is determined that the accelerator pedal of the target vehicle is depressed, recording the accumulated time duration during which the first driving force corresponding to the stroke of the accelerator pedal does not reach the target driving force;

[0133] When it is determined that the accumulated time exceeds a second threshold, the electronic parking caliper is controlled to be clamped.

[0134] In the embodiment of the present application, if the driver steps on the accelerator pedal, but the first driving force corresponding to the stroke of the accelerator pedal does not reach the target driving force, and the duration is relatively long, for the sake of safety, the electronic parking caliper can be pulled up again to park the vehicle. Specifically, in the embodiment of the present application, the cumulative duration of the first driving force corresponding to the stroke of the accelerator pedal not reaching the target driving force can be recorded, and a threshold value can be set specifically, recorded as the second threshold value. If the cumulative duration exceeds the second threshold value, the electronic parking caliper can be controlled to clamp again.
