[0048] Most existing automobiles are still in the mode of manual driving. When in the parking state, if the parking space is relatively small, or the adjacent parking space is parked irregularly, after parking is completed, the distance from the adjacent parking space is too close, the opening angle of the car door is small, and the driver cannot get out of the car smoothly.

[0049] Currently, high-end passenger cars have been installed with an automatic parking system that can use the automatic parking function, and the car can be parked in the parking space through remote control. However, most low-end passenger cars or commercial vehicles do not have an automatic parking system and can only be parked manually. Although the existing automatic parking system has powerful functions, its system is complex, including searching for a parking space, planning a parking path, making decisions and controlling each execution part of the car to complete the parking action, etc., resulting in high R & D costs and long development cycles, and it is not suitable for use in low-end passenger cars and commercial vehicles. Therefore, this application proposes an automatic parking system with simple functions and low costs.

[0050] Embodiment 1

[0051] The embodiment of the present application provides an automatic parking system.

[0052] See Figure 1 , Figure 1A structural schematic diagram of an automatic parking system provided by an embodiment of the present application is shown, comprising: a communication terminal 100 and a car 200; the car 200 comprises: an automatic parking device 201 and a braking device 202; the automatic parking device 201 comprises: at least one sensor module 2011; the sensor module 2011 is connected to the communication terminal 100 for communication, and is used to obtain distance information between the car 200 and an obstacle, and send the distance information to the communication terminal 100; the communication terminal 100 is connected to the braking device 202 for communication, and is used to send a preset parking instruction to the automatic parking device 201 according to the distance information; the automatic parking device 201 is also used to control the braking device 202 to park according to the preset parking instruction.

[0053] In this embodiment, the driver drives the car to the front of the parking space, turns on the straight-in and straight-out parking function through the communication terminal 100, leaves the cab, and closes the door. The automatic parking system controls the various components of the vehicle through the braking device 202 to achieve parking. During the parking process, the sensor module 2011 continuously monitors the distance information between the car 200 and the obstacle. When the distance is too close, an early warning is issued, and the user is reminded to adjust the steering wheel to prevent a collision accident.

[0054] The driver only needs to drive the vehicle to the front of the parking space and turn on the function, and then leave the cab, which greatly simplifies the parking process. Since the steps of searching for parking spaces and planning parking paths are omitted, the straight-in and straight-out parking method can complete parking quickly and improve time efficiency. And during the parking process, the system continuously detects obstacles and corrects the steering wheel in time to ensure safety. Real-time feedback and correction of the parking path help prevent collisions and improve parking safety. Compared with more complex autonomous driving parking systems, the straight-in and straight-out parking method is technically simpler and more direct. Due to the relatively low research and development and promotion costs, it is conducive to the application of this application in a wider range of models and markets.

[0055] In one embodiment, if Figure 2As shown in the figure, the automatic parking device 201 includes: a main control module 2013, a processing module 2012, a power management module 2015, and an internal communication module 2014; the power management module 2015 is electrically connected to the main control module 2013 and the sensing module 2011 respectively, and is used to step down and filter the obtained voltage and then supply power to each module; the processing module 2012 is communicatively connected to each sensing module 2011, and is used to receive the distance information sent by the sensing module 2011 and send the distance information to the main control module 2013; the internal communication module 2014 is communicatively connected to the communication terminal 100, the braking device 202, and the main control module 2013 respectively, and is used to receive the distance information sent by the main control module 2013 and control the braking device 202 to perform a preset action according to the obtained preset parking instruction and the distance information.

[0056] It should be noted that the power management module 2015 is used to step down and filter the obtained voltage to obtain a stable voltage, and output the stable voltage to the main control module 2013 for power supply. The main control module 2013 is used to control the sensing module 2011 to send ultrasonic pulse signals to the obstacle through the internal communication module 2014, and receive the echo signals returned by the obstacle according to each ultrasonic pulse signal, and calculate the obstacle distance information according to each echo signal.

[0057] Furthermore, according to the propagation speed of ultrasonic waves in the air (usually 340 m / s, but affected by factors such as temperature) and the time difference between the emission and return of ultrasonic waves, the main control module 2013 can calculate the distance to the obstacle. Among them, the distance information calculation formula is: distance = 1 / 2 × sound speed × time difference.

[0058] In an embodiment, the sensing module 2011 includes: a driving sub-module, an amplifying sub-module, and a control sub-module; the control sub-module is electrically connected to the driving sub-module and is used to control the driving sub-module to emit a first ultrasonic signal; the amplifying sub-module is electrically connected to the driving sub-module and the control sub-module respectively, and is used to obtain the first ultrasonic signal from the driving sub-module, amplify the first ultrasonic signal to a second ultrasonic signal, and send the second ultrasonic signal to the control sub-module; the control sub-module is also communicatively connected to the processing module 2012, and is also used to send the second ultrasonic signal to the obstacle, receive the echo signal returned by the obstacle according to the second ultrasonic signal, calculate the distance information according to the echo signal, and send the distance information to the processing module 2012.

[0059] It should be noted that the driving sub-module provides sufficient voltage and current for the probe core in the ultrasonic radar sensor to generate ultrasonic signals with sufficient intensity. The probe core is usually a piezoelectric ceramic sheet, which generates mechanical vibrations when a voltage is applied, thereby emitting ultrasonic waves. When ultrasonic waves are received, the vibrations are converted into electrical signals. The amplification sub-module amplifies the ultrasonic signal after obtaining it so that it can be recognized by the control sub-module.

[0060] In one embodiment, the control sub-module further includes: an AD converter; the AD converter is electrically connected to the amplification sub-module and is used to convert the second ultrasonic signal into a digital signal and send it to the obstacle.

[0061] In one embodiment, the sensing module 2011 includes: a plurality of ultrasonic radar sensors; each of the ultrasonic radar sensors is communicatively connected to the processing module 2012 and is electrically connected to the power management module 2015.

[0062] In this embodiment, as Figure 3 shown, the automatic parking device 201 is responsible for controlling 12 ultrasonic radar sensors, making decisions based on the distance data returned by each sensor, and then communicating with each component of the vehicle 200 through a communication bus to control the vehicle 200 to complete driving actions such as moving forward, backward, turning, and braking, and complete the parking function of driving straight in and out. In other embodiments, the number of ultrasonic radar sensors can be set according to requirements and is not limited herein.

[0063] In one embodiment, the automatic parking device 201 further includes: an alarm sub-module; the alarm sub-module is communicatively connected to the main control module 2013 and is used to send a warning message through the main control module 2013 when the distance information is less than a preset distance threshold.

[0064] For example, when the distance information obtained by the sensing module 2011 is less than 30 cm, the main control module 2013 immediately sends a control signal to the alarm sub-module to instruct it to send a warning message. The warning message includes: sound warning, optical signal warning, display screen warning, and display screen warning of the communication terminal 100. The specific warning message and the preset distance threshold can be set according to requirements and are not limited herein.

[0065] In one embodiment, the communication terminal 100 includes: a stop button module; the stop button module is respectively communicatively connected to the alarm sub-module and the braking device 202 and is used to control the braking device 202 to stop running according to the warning message.

[0066] It should be noted that the communication terminal 100 and the automobile 200 are wirelessly connected via Bluetooth or other wireless communication methods, and the communication terminal 100 can be a mobile phone APP or a Bluetooth controller. The communication terminal 100 displays the entire parking process, and can perform manual control parking or automatic control parking, mainly including the following button functions: (1) preparation button, (2) one-key direct entry, (3) one-key direct exit, (4) manual forward, (5) manual reverse, (6) emergency stop, and (7) current status / current progress display (reminder) function.

[0067] Parking control of the car through mobile devices allows users to start and control the parking process without entering the car. Especially in narrow or crowded parking environments, users can easily monitor and operate the vehicle to park in or out of the parking space through the communication terminal outside the car, greatly improving the convenience of use.

[0068] In one embodiment, the communication terminal 100 includes: an execution button module; the execution button module is respectively communicated with the braking device 202 and the automatic parking device 201, and is used to determine the preset parking instruction according to the distance information, and control the braking device 202 to perform a preset action according to the preset parking instruction.

[0069] In this embodiment, after the parking action is selected through the communication terminal 100, the braking device 202 controls various parts of the automobile 200 to park until the parking is successfully completed.

[0070] In one embodiment, the communication terminal 100 includes: a communication terminal 100 display screen; the communication terminal 100 display screen is respectively communicatively connected to the braking device 202 and the automatic parking device 201, and is used to obtain the parking status according to the automatic parking device 201 and display the parking status, wherein the parking status includes: a completed status and an unfinished status.

[0071] It should be noted that the parking status is displayed through the communication terminal 100. The completed status includes: when the vehicle successfully completes the parking operation, that is, the vehicle is safely parked in the predetermined parking space, and all related automatic parking actions are completed, the automatic parking system will notify the display screen of the communication terminal 100, and the display screen will then update the parking status to "completed status". The unfinished status includes: during the automatic parking process, as long as the vehicle has not reached the above-mentioned "completed status", it is considered to be in an "unfinished status". This may include any stage of searching for a parking space, adjusting the vehicle position to enter the parking space, or suspending the parking operation for some reason (such as detecting an obstacle).

[0072] Further, the communication terminal 100 can also display the parking progress. By obtaining the parking status in real time, corresponding instructions can be directly given according to the parking status, avoiding situations such as collisions.

[0073] In one embodiment, the system further includes: an in-vehicle display screen; the in-vehicle display screen is communicatively connected to the communication terminal 100 and is used to obtain the distance information and display the distance information.

[0074] The present invention provides an automatic parking system, including: a communication terminal 100 and an automobile 200; the automobile 200 includes: an automatic parking device 201 and a braking device 202; the automatic parking device 201 includes: at least one sensing module 2011; the sensing module 2011 is communicatively connected to the communication terminal 100 and is used to obtain the distance information between the automobile 200 and an obstacle and send the distance information to the communication terminal 100; the communication terminal 100 is communicatively connected to the braking device 202 and is used to send a preset parking instruction to the automatic parking device 201 according to the distance information; the automatic parking device 201 is further used to control the braking device 202 to park according to the preset parking instruction.
