Problems solved by technology

Therefore, when the driver passes through some road sections with complex scenes, he does not hesitate to turn around and adjust the direction before returning to pass through the complex road sections. This not only reduces driving efficiency and unnecessary energy consumption, but also brings a bad driving experience.

[0056] see figure 1 , is a schematic flow chart of an automatic reversing method provided in this embodiment, the automatic reversing method includes the following steps:

[0057] S101: During the advancing process of the target vehicle, record the advancing track of the target vehicle.

[0058] In this embodiment, any vehicle that realizes automatic backing by adopting this embodiment is defined as a target vehicle. During the forward driving process of the target vehicle, the position information of the target vehicle can be detected in real time and stored in the local database of the target vehicle, thereby recording the forward track of the target vehicle.

[0059] It can be understood that if the vehicle position information is recorded infinitely, the storage space of the local database will be completely occupied. Therefore, in order to save the storage space of the local database, and considering that the driver usually performs a reversing behavior within the vicin...

[0070] It should be noted that this embodiment will introduce the specific implementation manner of S101 in the first embodiment through the following step S401.

[0071] see Figure 4 , is a schematic flow chart of an automatic reversing method provided in this embodiment, the automatic reversing method includes the following steps:

[0072] S401: During the advancing process of the target vehicle, record the vehicle position of the target vehicle at each recording moment, and use each recorded vehicle position to form a forward trajectory of the target vehicle.

[0073] During the forward process of the vehicle, the positioning system can be used to continuously obtain the vehicle position of the target vehicle according to a preset time interval (such as every 0.5 seconds), specifically, the rear axle center of the target vehicle can be obtained (such as Figure 5 shown), or obtain the position change coordinates of other vehicle parts.

[0082] It should be noted that this embodiment will introduce the specific implementation manner of S102 in the first embodiment through the following steps S601-S604.

[0083] see Image 6 , is a schematic flow chart of an automatic reversing method provided in this embodiment, the automatic reversing method includes the following steps:

[0084] S601: During the advancing process of the target vehicle, record the advancing trajectory of the target vehicle.

[0085]It should be noted that this step S601 is consistent with S101 in the above-mentioned first embodiment. For relevant details, please refer to the introduction of the first embodiment, which will not be repeated here. Of course, this step S601 can also be replaced by S401 of the second embodiment or its specific implementation manner. For relevant details, please refer to the introduction of the second embodiment, and details will not be repeated here.

Abstract

The invention discloses an automatic reversing method and device. The method comprises the steps of recording a moving-forward trajectory of a target vehicle during the moving-forward process of the target vehicle, controlling the target vehicle to start to reverse from the current position if an automatic reversing command to the target vehicle is detected after the target vehicle stops moving forward, allowing the target vehicle to backtrack along the moving-forward trajectory by correcting a steering wheel angle of the target vehicle at each reversing moment, and controlling the target vehicle to stop reversing if a reversing stop command to the target vehicle is detected during the reversing process. The automatic reversing method and device can control the target vehicle to backtrackalong the moving-forward trajectory based on the recorded moving-forward trajectory, so that a driver can return without the need for controlling the vehicle to turn around so as to increase the efficiency of the vehicle in the return process and to improve the driving experience of the driver.

Description

technical field [0001] The present application relates to the technical field of automatic control, in particular to an automatic reversing method and device. Background technique [0002] In the actual driving process, the driver is usually able to control the path planning and driving control in the forward direction relatively skillfully. And reversing is also an action that will inevitably be performed during driving. Because cars generally adopt the steering principle of front-wheel drive vehicles, this enables the driver to flexibly control the reversing track when reversing. In the actual driving process, reversing is mostly used for low-speed driving. , Scenes with high mobility requirements, such as parking, passing on narrow roads, etc. [0003] However, it is often difficult for the driver to cope with the slightly complicated reversing scene. This is because the orientation of the driver's seat is the direction of forward driving, so that the field of vision du...
