[0043] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0044] It should be clear that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] Embodiment 1

[0046] This embodiment provides a vehicle safe driving control method, which can be executed by a vehicle safe driving control device implemented by software and / or hardware. The device can be deployed on a vehicle driving control device to control the safe driving of the vehicle. Figure 1 The method includes the following steps 101-103.

[0047] Step 101: Perform virus detection on an external memory connected to a vehicle driving control device.

[0048] In this step, the vehicle driving control device is provided with a CPU chip and an internal memory for controlling the vehicle driving. For example, the control device may be an onboard computer. External memory refers to storage other than the vehicle driving control device memory and the CPU cache, such as a USB flash drive, a hard disk, a floppy disk or an optical disk, etc. When performing virus detection on the external memory, only a local virus library may be used for virus detection, or a powerful cloud virus library may be connected to the network and used for virus detection. As a preferred embodiment, performing virus detection on the external memory connected to the vehicle driving control device includes:

[0049] When the connection between the external storage and the vehicle driving control device is established, a local virus library search is performed on the connected external storage to detect whether the connected external storage has a local virus;

[0050] If there is no local virus, the external storage is started, the cloud virus database is connected to the network, and the cloud virus database is checked for the connected external storage; after the connected external storage has no cloud virus, it is determined that access to the external storage is allowed.

[0051] Optionally, after searching the local virus database of the connected external storage to detect whether the connected external storage has local viruses, the method further includes: if there are local viruses, disconnecting the external storage and / or issuing an alarm.

[0052] Preferably, the method provided in this embodiment further includes: connecting to a cloud virus database according to a set period, and using the cloud virus database to update the local virus database.

[0053] Furthermore, the method provided in this embodiment also includes: when the traffic of communicating with the cloud after connecting to the network exceeds a set threshold, the connection with the cloud is automatically cut off and the whole machine scan is started.

[0054] The above-mentioned setting period and setting threshold can be set by those skilled in the art based on experience.

[0055] Step 102: After determining that the connected external memory is virus-free and access to the external memory is allowed, obtain the current driving mode of the vehicle.

[0056] In this step, the vehicle driving mode can be divided into: automatic driving mode and manual driving mode, or divided into: full automatic driving mode, semi-automatic driving mode and manual driving mode. A parameter for identifying the vehicle driving mode can be pre-set, and the initial value of the parameter can be defaulted to the value corresponding to the manual driving mode, and the parameter value can be dynamically modified in real time according to the actual driving state of the vehicle. The current driving mode of the vehicle can be obtained by reading the parameter value.

[0057] Step 103: Setting content reading permissions corresponding to the driving mode for the connected external memory.

[0058] In this step, not only is the content reading permission set for the connected external memory, but more importantly, the content reading permission in the external memory is determined according to the current driving mode of the vehicle. For example, in the automatic driving mode, the vehicle driving control device is relatively easy to be infected with viruses. Once the virus invades, it will threaten the automatic driving of the vehicle driving control device. Therefore, it can be set to allow only a small amount of file content (such as the first type of file content) in the external memory to be read; in the manual driving mode, the possibility of the vehicle driving control device being infected by the virus is relatively low. Even if the virus invades, the driving safety is not easily affected by manual control of the vehicle driving, so it can be set to restrict only a small number of file contents (such as the second type of file content) in the external memory from being read. Among them, the first type of file content can be a file content that is not easily infected by viruses according to historical statistics or experience; on the contrary, the second type of file content can be a file content that is easily infected by viruses according to historical statistics or experience. In addition, the first type of file content can also include file content that must be read for the automatic driving process.

[0059] Embodiment 2

[0060] This embodiment provides another vehicle safe driving control method based on the above embodiment 1. The method can be executed by a vehicle safe driving control device implemented by software and / or hardware, and the device can be deployed on a vehicle driving control device to control the safe driving of the vehicle. Figure 2 The method specifically includes the following steps 200-204.

[0061] Step 201: Perform virus detection on an external memory connected to a vehicle driving control device.

[0062] Step 202: After determining that the connected external memory is virus-free and access to the external memory is allowed, obtain the current driving mode of the vehicle.

[0063] Step 203: Setting content reading permissions corresponding to the driving mode for the connected external memory.

[0064] The above steps 201 to 203 are the same as the steps 101 to 103 in the above embodiment 1, and are not described again here.

[0065] Step 204: When it is monitored that other processes other than the processes required for vehicle driving are started, a vehicle driving safety hazard detection is performed.

[0066] In this step 204, preferably, when the vehicle driving mode is the automatic driving mode, the process of the operating system running the vehicle driving control device can be monitored in real time. If it is monitored that other processes other than the processes that need to be run for vehicle driving are started, it is immediately detected whether there are safety hazards in vehicle driving. Of course, vehicle driving safety hazard detection can also be performed when the vehicle driving mode is the manual driving mode. Specifically, the vehicle driving safety hazard detection process may include: scanning the vehicle driving control device as a whole machine to check whether the device has security vulnerabilities. Alternatively, it is also possible to only detect other processes other than the processes that need to be run for vehicle driving that are started and only scan the other processes to check whether there are malicious operations, such as whether there are external connections, whether there are query operations on system-level directories, etc. Further, if it is detected that there are security vulnerabilities in the device, or other processes other than the processes that need to be run for vehicle driving have malicious operations, a safety hazard prompt is performed, such as issuing a sound and light pop-up window prompt to prompt the user to manually choose to exit the current vehicle driving mode, or the device itself actively exits the current vehicle driving mode while the safety hazard prompt is performed.

[0067] As a preferred implementation, after performing the vehicle driving safety hazard detection, the vehicle safe driving control method provided in this embodiment further includes step 205:

[0068] If a safety hazard is detected and the vehicle fails to exit the current driving mode, the vehicle driving control device is switched to a new operating system so that the new operating system can restore the vehicle driving state before the switch and take over the old operating system for vehicle driving control.

[0069] The triggering of the system switching operation may be automatically triggered when the condition that there is a safety hazard and the vehicle fails to exit the current driving mode is met, or it may be triggered when the user operation is detected to be consistent with the preset system switching operation after the condition is met. Exemplarily, the operating systems before and after the switching are different underlying operating systems, for example, one is an Android operating system and the other is an IOS operating system. Preferably, in order to ensure the normal operation and function of the vehicle, the new operating system after the switching may not be provided with an interface for connecting to an external device.

[0070] Embodiment 3

[0071] This embodiment provides a preferred embodiment based on the above embodiments. This embodiment takes the vehicle as a car, the vehicle driving control device as a car onboard computer, and the external memory as a USB flash drive as an example to provide a safe driving control method. Of course, this preferred embodiment is also applicable to other types of vehicles, vehicle driving control devices, and external memories. Specifically, the method includes the following steps:

[0072] Step 1: Create a cloud virus database and a local virus database. The onboard computer of the car can connect to the cloud virus database through the network and update the local virus database through the cloud virus database according to the set period.

[0073] Step 2: When the USB flash drive is inserted, the car's onboard computer searches the local virus database for the USB flash drive to detect whether there are local viruses. If there are no local viruses, the USB flash drive is started and step 3 is executed. If there are local viruses, the USB flash drive is ejected and an alarm is issued.

[0074] Step 3: The car's onboard computer starts to connect to the cloud virus database and perform cloud virus database scan on the USB flash drive. After the USB flash drive is free of cloud viruses, it is confirmed that reading the contents of the USB flash drive is allowed.

[0075] Step 4: If the current driving mode of the car is the automatic driving mode, the car's onboard computer activates the whitelist function to limit the reading of the content in the USB flash drive, and only allows the setting file content in the whitelist to be read, such as music.

[0076] If the current driving mode of the car is manual driving mode, the car's onboard computer activates the blacklist function to limit the reading of the contents in the USB flash drive, and only restricts the reading of the setting file contents in the blacklist, such as XX.

[0077] Typically, when the car is in the automatic driving mode, after the U disk content is allowed to be read, the car's onboard computer monitors the system process. When monitoring the start of other processes other than the process required for the vehicle's automatic driving, the car's onboard computer prompts the user that the current automatic driving mode has safety hazards and scans the entire machine at the same time. Among them, the user prompt can be a prompt such as a sound and light pop-up window to the user, prompting the user to actively choose to exit the automatic driving mode. If the whole machine scan finds that there is a vulnerability, but the automatic driving mode cannot be exited, the user can switch to another operating system with a different underlying layer by long pressing the physical button of the switching system for 5S (to prevent accidental touch), such as the first system is the Android underlying layer, and the second system is the IOS underlying layer. The new operating system takes over the current car status and related parameters, and the first operating system defaults to the shutdown state. The external interface of the car's onboard computer is based on the first operating system. The second operating system does not have an interface for connecting to external devices. Its main function is to ensure the normal operation and function of the vehicle without any danger. The first operating system has the admin permission for the vehicle (it can work normally, but the permission for core file operations is insufficient), and the second operating system has the root permission for the vehicle (it has the highest authority over the vehicle and the car's onboard computer); when ROOT logs in, other accounts lose all permissions.

[0078] Step 5: When the vehicle computer is in networking mode, add traffic monitoring for communication with the cloud, set the traffic threshold to trigger an alarm and cut off the network connection. For example, when the transmission protocol is http, the communication traffic is 10M / S under normal conditions, and the threshold is set to 30M. If the current traffic size exceeds the threshold, the connection with the cloud is automatically cut off and the whole machine scan is started.

[0079] In addition, an embodiment of the present invention also provides a vehicle safety driving control device, see Figure 3 , the device comprises:

[0085] If there is no local virus, the external storage is started, the cloud virus database is connected to the network, and the cloud virus database is checked for the connected external storage; after the connected external storage has no cloud virus, it is determined that access to the external storage is allowed.
