[0045] Here, the exemplary embodiments will be described in detail, and the examples are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure.

These terms are only used to distinguish the same type of information from each other.

[0048] Currently, with the increasing popularity of intelligent vehicles represented by electric vehicles, users' demand for the assisted driving experience is also constantly rising. However, since the current different assisted driving modules of the vehicle are respectively connected to the vehicle's control system, when the vehicle switches between different assisted driving functions currently, there will be a short time gap without any assisted driving function, and at this time, the vehicle has a risk of getting out of control, posing a safety hazard to users.

[0049] As Figure 1 shown, in the current intelligent driving domain controller, different assisted driving modules are respectively connected to the vehicle's control system (such as the chassis domain controller) through independent interfaces. In one example, when the user switches the current first assisted driving function to the second assisted driving function, the first assisted driving function module will first disconnect from the chassis domain controller. After that, the second assisted driving function module will connect to the chassis domain controller, and during the above process, there is a short time gap without any assisted driving function, and at this time, the vehicle has a risk of getting out of control, posing a safety hazard to users.

[0050] In view of this, the present disclosure provides a vehicle control method to at least solve the technical problems existing in the related art. The method of the present disclosure is applied to a vehicle provided with an intelligent driving domain controller, and the intelligent driving domain controller includes at least two intelligent driving function modules and is provided with a unified interface for establishing a handshake connection with the chassis domain controller.

[0051] Among them, the intelligent driving domain controller represents an element that integrates vehicle intelligent driving related function information, including assisted driving functions and / or autonomous driving functions, such as an autonomous driving domain controller (ADCU, Automated Driving Control Unit). The intelligent driving domain controller includes at least two intelligent driving function modules, which can be used to execute assisted driving functions at vehicle levels L1 to L4, such as high-speed assisted driving function (HWA, High Way Assist), automated assisted navigation driving function (NOP, Navigate on Pilot), city pilot function (CPT, City Pilot), etc.

[0052] In addition, the intelligent driving domain controller is also provided with a unified interface for establishing a handshake connection with the chassis domain controller, so that each intelligent driving function module in the intelligent domain controller can interact with other domain controllers through the same interface.

[0053] Figure 2 Shows a flowchart of a vehicle control method according to an exemplary embodiment of the present disclosure.

[0054] In step S101, in response to receiving a first activation instruction, control the first advanced driving assistance function module to connect to the unified interface, and control the unified interface to establish a handshake connection with the chassis domain controller.

[0055] Optionally, the first activation instruction, which represents a control instruction for triggering the first advanced driving assistance function, can be actively triggered by the user or automatically triggered by the intelligent driving domain controller. The first advanced driving assistance function module represents the relevant control algorithms for executing the first advanced driving assistance function, and can include any advanced driving assistance system (ADAS) function among the at least two intelligent driving functions, such as the high-way assist (HWA) function, the navigate on pilot (NOP) function, the city pilot (CPT) function, etc. The chassis domain controller represents the vehicle's motion control actuator, including the lateral braking system and the longitudinal braking system.

[0056] In the case of receiving the first activation instruction, by controlling the first advanced driving assistance function module to connect to the unified interface and controlling the unified interface to establish a handshake connection with the chassis domain controller, the first advanced driving assistance function module can perform handshake interaction with the chassis domain controller, facilitating information transmission, alphabet verification, or other protocol validations, so as to enable the vehicle to activate the first advanced driving assistance function.

[0057] In step S102, in response to receiving a second activation instruction, control the second advanced driving assistance function module to connect to the unified interface, and control the first advanced driving assistance function module to disconnect from the unified interface.

[0058] Optionally, the second activation instruction, which represents a control instruction for triggering the second advanced driving assistance function, can also be actively triggered by the user or automatically triggered by the intelligent driving domain controller. The second advanced driving assistance function module represents the relevant control algorithms for executing the second advanced driving assistance function, and can include any function among the at least two intelligent driving functions other than the first advanced driving assistance function.

[0059] Figure 3 FIG. shows a schematic diagram of a vehicle control method according to an exemplary embodiment of the present disclosure.

[0060] Upon receiving the second activation instruction, indicating that the current vehicle needs to perform a switching operation of the intelligent driving function, it is possible to control the second auxiliary driving function module to connect to the unified interface and control the first auxiliary driving function module to disconnect from the unified interface. That is to say, when the unified interface maintains a handshake connection with the chassis domain controller, the switching process of the auxiliary driving function module is completed inside the intelligent driving domain controller. When the second auxiliary driving function module performs a handshake interaction with the chassis threshold controller, the vehicle can start the second auxiliary driving function.

[0061] In the solution described in the present disclosure, by maintaining the handshake connection between the unified interface and the chassis domain controller and performing the switching of the auxiliary driving function module inside the intelligent driving domain controller, the seamless switching of the intelligent driving function of the vehicle is achieved, without time gaps and out-of-control risks, improving the safety of the vehicle and users.

[0062] In an optional embodiment, the method further includes:

[0063] In response to receiving an exit instruction for the auxiliary driving function, control the intelligent driving domain controller to disconnect the handshake connection with the chassis domain controller.

[0064] Specifically, when the intelligent driving function currently executed by the vehicle exits, the handshake connection between the intelligent driving domain controller and the chassis domain controller can be directly interrupted, and the intelligent driving domain controller is controlled to end the current intelligent driving function.

[0065] In an optional embodiment, the method further includes:

[0066] In response to the vehicle being powered on, detect whether the vehicle currently meets the intelligent driving function activation condition;

[0067] When the vehicle currently meets the intelligent driving function activation condition, obtain the activation instruction for the first auxiliary driving function.

[0068] Specifically, before performing the above method, after the vehicle is powered on, the chassis threshold controller can be controlled to perform a self-check on the vehicle health status and determine whether to receive the activation instruction according to the vehicle health status.

[0069] Exemplarily, the detection of whether the vehicle currently meets the intelligent driving function activation condition includes:

[0070] Determine the current vehicle condition status:

[0071] When the current vehicle has no faults and the current vehicle battery level is not lower than a preset battery level value, it is determined that the vehicle currently meets the intelligent driving function activation condition;

[0072] Otherwise, it is determined that the vehicle currently does not meet the conditions for enabling the intelligent driving function.

[0073] Specifically, it can be determined whether the current vehicle has a vehicle-wide failure. For example, it can be detected whether there is an abnormal display of the tire pressure monitoring system (TMPS light on) or a motor failure (TM light on) through the electronic control unit (ECU, Electronic Control Unit) to determine whether the current vehicle meets the conditions for enabling the intelligent driving function. Or the remaining power of the vehicle can be obtained through the power management controller of the vehicle. After the remaining power is lower than the preset power value, the intelligent driving function is prohibited from starting to prompt the user, so as to avoid danger caused by the shutdown of the vehicle system.

[0074] In an optional embodiment, when the vehicle is provided with a parking domain controller, the method further includes:

[0075] In response to receiving an activation instruction for the parking function, control the parking domain controller to be connected to the unified interface through the intelligent driving domain controller, and control the intelligent driving domain controller to establish a handshake connection with the chassis domain controller through the unified interface to start the parking function.

[0076] Among them, the parking domain controller can establish a handshake connection with the chassis domain controller through the unified interface of the intelligent driving domain controller to implement the parking function, realizing the interface integration of the parking domain controller and the intelligent driving domain controller.
