[0071] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0072] The same reference numerals in the drawings represent the same or similar elements, components or parts, and thus the repeated description of the same or similar elements, components or parts may be omitted below. It should also be understood that although the first, second, third and other attributives representing the numbers may be used herein to describe various devices, elements, components or parts, these devices, elements, components or parts should not be limited by these attributives. In other words, these attributives are only used to distinguish one from another. For example, the first device may also be called the second device, but it does not deviate from the essential technical solution of the present invention. In addition, the terms "and / or" and "and / or" refer to all combinations including any one or more of the listed items.

[0073] See also Figure 1 , Figure 1 FIG. 1 is a flow chart of a vehicle mode switching method provided by the present invention. Figure 1 As shown, the method includes:

[0074] S11. When the vehicle meets the first preset condition, if the mode switching controller receives a diagnosis instruction, it sends a vehicle mode signal corresponding to the diagnosis instruction.

[0075] In this embodiment, when the vehicle switches the whole vehicle mode, it is generally required that the vehicle is in the starting state, the vehicle is stopped or the speed is low, and the gear of the vehicle is in the stop gear, etc., so that the vehicle can ensure the driving safety when the vehicle switches the whole vehicle mode. The first preset condition can be that the vehicle power mode is ON and not Crank On, the speed is ≤2KM / h, and the vehicle gear is P gear. Of course, there are control requirements for other components of the vehicle, which will not be repeated in this solution.

[0076] In this embodiment, the vehicle mode includes: factory mode / transportation mode, user mode and exhibition hall mode, etc. Different modes are applied to different vehicle situations. For example, transportation mode: mainly to meet the needs of long-distance transportation scenarios. In transportation mode, due to the long shipping cycle, in order to prevent power outage, most self-wake-up conditions and irrelevant functions will be restricted in transportation mode; when the controller enters sleep mode after the vehicle is powered off, the controller with deep sleep state immediately enters deep sleep state. Exhibition hall mode: mainly to meet the needs of venue exhibitions. In exhibition hall mode, only vehicle power will be restricted, high voltage cannot be powered on to PT_Ready, and other functions are normal. User mode: User mode is the normal use mode, the vehicle is in full-function state, and no restrictions are imposed.

[0077] In this embodiment, according to the usage requirements of different scenarios, the vehicle mode switching can be completed through diagnostic instructions to ensure the safety of users.

[0078] In this embodiment, the current scene can be determined by identifying the vehicle's surroundings and the vehicle's status, and a diagnostic instruction can be generated based on the usage requirements of the current scene so that the vehicle can complete the vehicle mode switch. For example, when the vehicle is transported to the exhibition hall, the exhibition hall environment can be collected by the sensors and video devices installed on the vehicle. At this time, it is necessary to switch from user mode or transportation mode to exhibition hall mode, and generate corresponding diagnostic instructions to achieve the vehicle mode switch. The staff can also enter the current scene according to current needs, determine whether the vehicle mode needs to be switched based on the entered current scene information, and generate diagnostic instructions to complete the vehicle mode switch when the vehicle mode needs to be switched. Of course, the current scene and the usage requirements of the current scene can also be determined in other ways, and this solution does not specifically limit this.

[0079] In this embodiment, the mode switching controller is a key component of the automotive electronic control system, which is responsible for regulating the vehicle's driving mode; after receiving the diagnostic instruction to switch the vehicle mode, the mode switching controller sends a corresponding vehicle mode signal to switch the vehicle mode, and the vehicle mode signal includes: 1) Transport mode: the vehicle mode signal is (0x431, CEM_1_CarMode=0x3: Transport Mode) 2) Exhibition hall mode: the vehicle mode signal is (0x431, CEM_1_CarMode=0x4: Exhibition Mod) 3) User mode: the vehicle mode signal is (0x431, CEM_1_CarMode=0x1: NormalMode), and the characters corresponding to each vehicle mode are the character instructions corresponding to different vehicle modes in the vehicle system.

[0080] S12: The power switching controller receives the vehicle mode signal and sends a power switching signal corresponding to the vehicle mode signal.

[0081] In this embodiment, the power switching controller can be a central control system in the vehicle, which can display the received vehicle mode signal on the central control display of the central control system and prompt the vehicle mode to be switched. Furthermore, a vehicle mode switching pop-up window can pop up, and the user can further determine whether to switch the vehicle mode. It can also be other processor systems that receive the vehicle mode signal fed back by the mode switching controller to generate the power switching signal.

[0082] In this embodiment, after the power switching controller receives the vehicle mode signal, it sends a corresponding power switching signal: 1) After receiving the vehicle mode signal (0x431, CEM_1_CarMode=0x3: TransportMode), the power switching controller sends a power switching signal (0x532, ShowRoomSwt=0x1: Close) 2) After receiving the vehicle mode signal (0x431, CEM_1_CarMode=0x4: Exhibition Mode), the power switching controller sends a power switching signal (0x532, ShowRoomSwt=0x2: Open) 3) After receiving the vehicle mode signal (0x431, CEM_1_CarMode=0x1: Normal Mode), the power switching controller sends a power switching signal (0x532, ShowRoomSwt=0x1: Close); After receiving the character instructions of the above-mentioned vehicle mode, the power switching controller generates a corresponding power switching signal. The characters corresponding to the power switching signal in this scheme are the character instructions corresponding to different power switching signals in the vehicle system.

[0083] S13, the vehicle power controller receives the power switching signal and switches the vehicle to a corresponding power state.

[0084] In this embodiment, the vehicle power controller may be an HCU (Hybrid Control Unit), i.e., a hybrid vehicle controller, which is a core control component in a hybrid vehicle. HCU is widely used in hybrid vehicles. Through the precise control and management of HCU, the goals of low fuel consumption, low emissions and high energy efficiency are achieved. At the same time, HCU also provides a smooth and responsive driving experience, meeting consumers' high-quality demands for hybrid vehicles.

[0085] In this embodiment, the vehicle power state is controlled by the vehicle power controller according to the power switching signal, so that the vehicle enters the corresponding vehicle mode.

[0086] In this embodiment, when switching the vehicle mode, in addition to the vehicle power, other components in the vehicle need to be controlled. For example, in the transport mode, in addition to power limitation, components such as wipers, air conditioners, and window glass need to be controlled. In this solution, the vehicle mode signal will also be sent to other controllers of the vehicle, and other controllers will control the corresponding vehicle components respectively. Specifically, the other relevant controllers receive the vehicle mode signal sent by the mode switching controller (according to the vehicle mode status and the "vehicle mode function execution table", and execute the vehicle mode switching. The "vehicle mode function execution table" is pre-configured in the vehicle's control table and called when the vehicle mode is switched.

[0087] In the present disclosure, when the vehicle meets the first preset condition, the mode switching controller will respond to the received diagnostic instruction and issue a vehicle mode signal that matches the diagnostic instruction. This signal is then received by the power switching controller, and a corresponding power switching signal is issued according to its content. Finally, after receiving this power switching signal, the vehicle power controller will perform corresponding operations to switch the vehicle to a specified power state. This series of processes ensures that when the vehicle faces specific diagnostic needs, it can quickly and accurately adjust its power mode to adapt to different operations or safety needs.

[0088] See also Figure 2 , Figure 2 The second flow chart of a vehicle mode switching method provided by the present invention is as follows: Figure 2 As shown, the vehicle mode signal includes: the signal of the exhibition hall mode; the switching method includes:

[0089] S21. When the vehicle switches to the power state corresponding to the showroom mode or switches from the power state corresponding to the showroom mode to other power states, the vehicle power controller feeds back a power execution state signal.

[0090] In this embodiment, when the vehicle switches to the power state corresponding to the exhibition hall mode or switches from the power state corresponding to the exhibition hall mode to other power states, that is, the vehicle is in the non-exhibition hall mode, the mode switching controller sends a signal corresponding to the exhibition hall mode, and at this time, it switches from the non-exhibition hall mode to the exhibition hall mode according to the signal of the exhibition hall mode; or, the vehicle is in the exhibition hall mode, the mode switching controller sends a signal corresponding to the non-exhibition hall mode, and at this time, it switches from the exhibition hall mode to the non-exhibition hall mode according to the signal of the non-exhibition hall mode.

[0091] In this embodiment, after the vehicle power controller controls the vehicle to switch to the exhibition hall mode or from the exhibition hall mode to the non-exhibition hall mode, it feeds back the power execution status signal. Specifically, when entering or exiting the exhibition hall mode, after the HCU executes, it needs to feed back the power execution status signal (0X416, HCU_ShowRoomRunngSts), (0X416, HCU_ShowRoomRunngSts) is the character corresponding to the power execution status signal.

[0092] S22: After receiving the power execution state signal, the mode switching controller feeds back the mode execution state signal.

[0093] In this embodiment, after the mode switching controller receives the HCU power execution status signal, it feeds back the mode execution status signal according to the power execution status signal (0X431, CarModeSts=0X1 exhibition hall mode entry is successful; CarModeSts=0X2 exhibition hall mode exit is successful; CarModeSts=0X3 exhibition hall mode entry failed; CarModeSts=0X4 exhibition hall mode exit failed; CarModeSts=0X5 power abnormality recovery in exhibition hall mode), that is, determines whether the exhibition hall mode entry or exit is successful through the power situation feedback from the vehicle power controller, as well as the power situation of the vehicle in the exhibition hall mode, and generates a corresponding mode execution status signal.

[0094] S23, the power switching controller controls the vehicle according to the received mode execution state signal and the preset function execution table.

[0095] In this embodiment, the mode execution status signal is fed back to the power switching controller, and the power switching controller controls the vehicle according to the mode execution status signal. If the exhibition hall mode fails to be entered, the user mode can be re-entered to avoid the vehicle being unusable. If the exhibition hall mode fails to be exited, the exhibition hall mode can be switched back to the exhibition hall mode. When the vehicle power is abnormally restored, the vehicle can be emergency braked and the staff can be prompted to handle it. For example, if the vehicle power is abnormally restored, the mode execution status signal is fed back to the central control system, and the mode execution status signal can be displayed in real time on the central control screen of the central control system. At the same time, the vehicle is controlled to brake to ensure the safety of the vehicle. A pop-up window "Exhibition hall mode failure, power system abnormal recovery, please ask the staff to check" can also be popped up on the central control screen. This pop-up window cannot be closed before the vehicle mode is successfully switched.

[0096] In a specific embodiment, Figure 3 As shown, the mode execution status signal includes: a successful entry signal of the exhibition hall mode and a failed entry signal of the exhibition hall mode; the vehicle mode switching method for entering the exhibition hall mode includes:

[0099] S32: When the mode switching controller receives the first power execution state signal within a preset time interval of sending the vehicle mode signal, the mode switching controller feeds back a showroom mode entry success signal to the power switching controller.

[0100] In this embodiment, the first power execution status signal is fed back by the vehicle power controller after the mode switching controller sends a signal of the exhibition hall mode. Since the switching speed of the vehicle mode is relatively fast, a preset time interval is set at this time to screen the identity of the feedback signal to ensure the security of the feedback signal received by the mode switching controller, avoid misjudgment of the mode switching controller due to abnormal signals sent by external intrusion, and improve the overall security of the system. The preset time interval in this scheme can be 7 seconds. Specifically, the mode switching controller receives the power execution status signal (0X416, HCU_ShowRoomRunngSts) within 7S of sending the signal (0x431, CEM_1_CarMode=0x4: Exhibition Mode), and sends a successful status signal of entering the exhibition hall mode (0X431, CarModeSts=0X1) to the power switching controller.

[0101] S33: The power switching controller prompts that the exhibition hall mode is turned on according to the received exhibition hall mode entry success signal, and displays power limitation information.

The signal received after the timeout may be an abnormal signal or the vehicle abnormally switches the vehicle mode. At this time, further control of the vehicle is required to avoid vehicle failure.

[0106] S42. The power switching controller prompts that the exhibition hall mode entry fails according to the received exhibition hall mode entry failure signal, and switches to the user mode; the user mode signal is one of the vehicle mode signals.
