Detailed ways

The present application will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, as long as there is no conflict, the embodiments and features in the embodiments of this application can be combined with each other.

In this embodiment, a method for switching the automatic driving function is provided. As shown in Figure 1, the method includes:

Step 101: When the vehicle is in the autonomous driving state of the first autonomous driving mode, perform automatic driving planning on the vehicle based on the first automatic driving mode and perform automatic driving control according to the planned first automatic driving data, and The second automatic driving mode performs automatic driving planning on the vehicle to obtain second automatic driving data.

In the embodiment of the present application, when the vehicle is in the autonomous driving state of the first autonomous driving mode, while performing autonomous driving control on the vehicle in accordance with the first autonomous driving mode, autonomous driving planning is performed on the vehicle based on the second autonomous driving mode. Specifically, perform automatic driving planning on the vehicle based on the first automatic driving mode to obtain the first automatic driving data, and perform automatic driving control according to the planned first automatic driving data. At the same time, the vehicle is automatically driven in the second automatic driving mode. Plan to obtain the second automatic driving data. In the first automatic driving mode of the vehicle, automatic driving control of the vehicle is only based on the first automatic driving data. The second automatic driving data does not participate in the automatic driving control of the vehicle.

For this reason, when the vehicle monitoring information meets the preset automatic driving mode switching conditions, based on the second automatic driving data corresponding to the second automatic driving mode calculated when the vehicle is controlled in the first automatic driving mode, it can be quickly The currently running first automatic driving mode is switched to the second automatic driving mode. That is, when the vehicle is in the first automatic driving mode, the automatic driving planning of the vehicle has been carried out in advance according to the second automatic driving mode, thereby obtaining the second automatic driving data. Therefore, when the vehicle needs to switch to the second automatic driving mode, The vehicle can then be controlled to perform automatic driving in the second automatic driving mode according to the obtained second automatic driving data, so that when the vehicle switches to the automatic driving mode, it does not need to wait for the preliminary planning calculation time of the second automatic driving mode. Switching to automatic driving in the second automatic driving mode realizes rapid switching between the two automatic driving modes and does not require manual operation by the user.

Further, as a refinement and expansion of the specific implementation of the above embodiment, in order to completely explain the specific implementation process of this embodiment, another method for switching the automatic driving function is provided. As shown in Figure 3, the method includes:

Step 201: When the vehicle is in the automatic driving state of the first automatic driving mode, perform automatic driving planning for the first automatic driving mode on the vehicle based on the preset first planning frequency corresponding to the first automatic driving mode, And perform automatic driving control based on the latest planned automatic driving data.

Step 202: Based on the preset second frequency reduction frequency corresponding to the second automatic driving mode, perform automatic driving planning for the second automatic driving mode on the vehicle to obtain second automatic driving data.

Wherein, the preset second planning frequency is greater than the preset second frequency reduction frequency.

In the embodiment of the present application, when the vehicle is in the autonomous driving state of the first autonomous driving mode, the autonomous driving planning of the first autonomous driving mode is performed on the vehicle based on the preset first planning frequency corresponding to the first autonomous driving mode, and based on The latest and first autonomous driving data planned are used for autonomous driving control. To this end, automatic driving planning of the first automatic driving mode is performed on the vehicle by presetting the first planning frequency, thereby realizing automatic driving control of the vehicle.

At the same time, based on the preset second frequency reduction frequency corresponding to the second automatic driving mode, automatic driving planning for the second automatic driving mode is performed on the vehicle to obtain the second automatic driving data.

Step 203: When it is recognized that the vehicle monitoring information of the vehicle satisfies the preset automatic driving mode switching condition, control the vehicle to enter the second automatic driving mode, and control the vehicle to enter the second automatic driving mode based on the preset third automatic driving mode corresponding to the second automatic driving mode. The second planning frequency performs automatic driving planning for the second automatic driving mode on the vehicle, and performs automatic driving control based on the latest planned second automatic driving data.

In the above embodiment, when the vehicle monitoring information of the vehicle is recognized to meet the preset automatic driving mode switching conditions, the vehicle is controlled to enter the second automatic driving mode. In order to ensure quick mode switching, the vehicle is first planned according to the last plan before the automatic driving mode switching. Carry out vehicle control based on the second automatic driving data, and then perform automatic driving control on the vehicle at the normal frequency (that is, the preset second planned frequency) in the second automatic driving mode of the vehicle. After each second automatic driving data planning, the vehicle is controlled according to the normal frequency (that is, the preset second planned frequency). The latest second autonomous driving data is used for real-time autonomous driving correction, allowing the vehicle to achieve autonomous driving in the second autonomous driving mode.

Step 204: Based on the preset first frequency reduction frequency corresponding to the first automatic driving mode, perform automatic driving planning for the first automatic driving mode on the vehicle to obtain third automatic driving data.

Wherein, the preset first planning frequency is greater than the preset first frequency reduction frequency.

In the above embodiment, in order to ensure rapid switching of the next automatic driving mode, in the second automatic driving mode of the vehicle, the vehicle performs the first automatic driving based on the preset first frequency reduction frequency corresponding to the first automatic driving mode. Autonomous driving planning of the mode to obtain the third autonomous driving data. Therefore, after the vehicle switches from the initial first automatic driving mode to the second automatic driving mode, automatic driving planning is performed for the first automatic driving mode before the mode switch by presetting the first frequency reduction frequency, and then the second automatic driving mode is obtained. Three automatic driving data are used to quickly switch to the first automatic driving mode when the vehicle's vehicle monitoring information once again meets the preset automatic driving mode switching conditions, which improves the efficiency of the vehicle in completing automatic driving function switching.

In the embodiment of the present application, in the automatic driving state of the vehicle, optionally, it also includes: when it is recognized that the vehicle monitoring information of the vehicle does not meet the preset automatic driving conditions, outputting a first prompt to exit the automatic driving mode. information, and enter the automatic function standby state of the vehicle; when the user's operation data for the vehicle is received and the preset automatic operation data matches, the vehicle enters the automatic function standby state or enters the manual mode of the vehicle. control status.

In the above embodiment, when it is recognized that the vehicle monitoring information of the vehicle does not meet the preset automatic driving conditions, the first prompt information to exit the automatic driving mode is output, and the vehicle enters the automatic function standby state. When the user's request for the vehicle is received, When the operation data matches the preset automatic operation data, the vehicle enters the vehicle's automatic function standby state or enters the vehicle's manual control state.

Specifically, the preset automatic operation data can include the software switch being turned off, the user taking over the steering wheel, the user stepping on the brakes, the vehicle detecting a line crossing operation when the vehicle is in a non-lane changing scenario, the road the vehicle is driving on is too narrow, etc.

By applying the technical solution of this embodiment, when the vehicle is in the autonomous driving state of the first autonomous driving mode, the autonomous driving planning of the first autonomous driving mode is performed on the vehicle by presetting the first planning frequency and then the autonomous driving control is performed. Preset the second frequency reduction frequency to perform automatic driving planning for the second automatic driving mode and obtain the second automatic driving data. When the vehicle meets the preset automatic driving mode switching conditions and enters the second automatic driving mode, the vehicle performs automatic driving planning for the second automatic driving mode through the preset second planning frequency and performs automatic driving based on the planned latest second automatic driving data. Driving control, while performing automatic driving planning for the first automatic driving mode of the vehicle according to the preset first frequency reduction frequency, and obtaining third automatic driving data. It achieves reasonable and flexible scheduling of different automatic driving modes for different driving scenarios, improving the efficiency of the vehicle in completing automatic driving function switching.

In the embodiment of this application, the autonomous driving mode of the vehicle is entered through the following methods, as shown in Figure 4, including:

Step 301: In response to a vehicle start signal, control the vehicle to enter a manual control state.

In the embodiment of this application, the vehicle status includes a manual control status and an automatic function status. After the driver starts the vehicle, he immediately controls the vehicle to enter the manual control state in response to the vehicle start signal.

After the vehicle is started, the automatic function state and manual control state can be switched through the system soft switch or other means. The automatic function state includes the automatic driving state. When the vehicle system is in the automatic function state, the driver can initiate a trigger to enter the automatic driving state by moving the vehicle's shift lever, clicking on the screen button or key, and take over the steering wheel, apply the brakes or Other preset ways to exit the autopilot state.

Step 302: Receive an automatic function entry instruction and control the vehicle to enter an automatic function standby state. The automatic function entry instruction is executed when the received user biometric information matches the preset biometric information and/or when the received user biometric information matches the preset biometric information. Generated when the user operation data matches the preset automatic operation data.

Next, the automatic function state also includes an automatic function standby state. After receiving the automatic function entry instruction, the vehicle is first controlled to enter the automatic function standby state. The automatic function entry instruction matches the received user biometric information with the preset biometric information. And/or generated when the received user operation data matches the preset automatic operation data. For example, the user can indicate the automatic function status through voice input, fingerprint input, lever operation, etc.

As shown in Figure 5, the default initial state when the vehicle enters the automatic function state from the manual state is the automatic function standby state. When the system deactivates automatic (exits automatic driving), it will jump to this state. The automatic function state includes automatic function standby state, preprocessing state and automatic driving state. Among them, the automatic driving state includes the CP state and the HNP state. The vehicle performs automatic driving in the CP mode in the CP state, and performs automatic driving in the HNP mode in the HNP state. The automatic function standby state is switched to any automatic driving state through the preprocessing state, and the preprocessing state is also used when switching between different automatic driving states. In the preprocessing state, the vehicle configuration to the automatic driving state is completed. For example, when preparing to switch to the CP state, the vehicle configuration in the CP state is performed in the preprocessing state.

In the preprocessing state, functional message interaction with the relevant algorithm modules of the vehicle system can be realized to complete a series of preparations before entering the autonomous driving state. Through the preparation and judgment of the system state, the stability of the vehicle system and driving safety can be ensured. . The functions implemented by the preprocessing state can include: setting the operating mode, switching planning output, setting the functional mode and setting the automatic enable, etc., as shown in Figure 6.

Among them, the operating mode is set, for example: notifying map, positioning, sensing, prediction, planning, control and other algorithm modules to start running (usually the mode is set to HIGHWAY). The operating mode includes HIGHWAY, PARKING, etc., that is, high speed and parking.

Setting functional modes, for example: frequency control operation in the planning algorithm, controlling the vehicle to be set to driving mode (used to distinguish driving mode and parking mode), positioning operation to record status, prediction operation to switch models, functional modes include HNP and CP, mode switching corresponds to the switching between HNP and CP in functional mode.

For example, setting automatic enablement is used to start controlling the vehicle based on the planned output, perform related operations on the wire-controlled chassis in the vehicle system, set the driving speed, set the time interval, and set the driving style (including aggressive, conventional, conservative, etc.), and the above settings are all Need to wait for the status to return. After the vehicle is automatically enabled for setting, the user can send a driving style setting request to the vehicle, and the vehicle can then set the time interval and then set the driving style.

As shown in Figure 7, the automatic function standby state includes empty standby state, CP standby state and HNP standby state that can be switched arbitrarily among each other. The empty standby state is the default state for entering the automatic function state. After detecting that HNP automatic driving has been satisfied, It enters the HNP standby state when the conditions are met, and enters the CP standby state when it is detected that the HNP automatic driving conditions are not met but the CP automatic driving conditions are met.

Step 303: If the user's automatic driving instruction is received and the vehicle is recognized to meet the preset automatic driving mode conditions, the vehicle is controlled to enter an automatic driving preparation state and the vehicle is configured for automatic driving.

Then, after receiving the automatic driving instruction actively triggered by the user, that is, when the user wants to start automatic driving, if it is recognized that the vehicle meets the preset automatic driving mode conditions, then the vehicle is controlled to enter the automatic driving preparation state, and Configure the vehicle for autonomous driving.

Step 304: If it is recognized that the vehicle meets the preset automatic driving conditions and does not receive the user's automatic driving instruction, output the second prompt information to enter the automatic driving mode, and after receiving the second prompt information, When the feedback information is confirmed or when the rejection feedback information is not received within a preset time period, the vehicle is controlled to enter an automatic driving preparation state and the vehicle is configured for automatic driving.

Then, when the automatic driving instruction actively triggered by the user is not received, but it is recognized that the vehicle meets the preset automatic driving conditions, the second prompt information for entering the automatic driving mode is output, and after receiving the response to the second prompt information When the feedback information is confirmed or the rejection feedback information is not received within the preset time period, the vehicle is controlled to enter the autonomous driving preparation state and the vehicle is configured for autonomous driving. In a specific application scenario, when the driver is driving the vehicle, if the vehicle meets the preset automatic driving conditions, but the driver is not aware of the current road conditions, it can perform automatic driving. That is, the vehicle does not receive any information at this time. According to the user's automatic driving instruction, the vehicle can output a second prompt message to enter the automatic driving mode to prompt the user whether to turn on the automatic driving mode. If the user clicks to confirm or does not click to reject within a preset time period, such as 5 minutes, then The vehicle is then controlled to enter the autonomous driving preparation state. In this application scenario, it can prevent the user from neglecting to turn on the autonomous driving mode due to focusing on traffic driving.

In this embodiment, the preset automatic driving conditions include highway navigation driving conditions and cruise assisted driving conditions. When configuring the vehicle for automatic driving in step 304, optionally, if the vehicle meets the highway navigation driving conditions , then perform highway navigation driving configuration on the vehicle; if the vehicle meets the cruise assisted driving condition and does not meet the highway navigation driving condition, perform cruise assisted driving configuration on the vehicle.
