[0018] Other features and advantages of the present invention will be better understood through the following detailed description of the optional embodiments in conjunction with the accompanying drawings, in which the same reference numerals identify the same or similar components, wherein:

[0019] Figure 1 is a schematic diagram of a driving mode control system of a vehicle according to an embodiment of the present invention;

[0020] Figure 2 is a flow chart of a driving mode control method of a vehicle according to an embodiment of the present invention;

[0021] Figure 3 is a flowchart of a driving mode control method of a vehicle according to another embodiment of the present invention. DETAILED DESCRIPTION

[0022] The implementation and use of the embodiments are discussed in detail below. However, it should be understood that the specific embodiments discussed are merely illustrative of specific ways to implement and use the invention, and are not intended to limit the scope of the invention.

[0023] Typically, new energy vehicles have high acceleration and deceleration performance. The inventors have realized that such high acceleration and deceleration performance of the vehicle may be uncomfortable for rear passengers, especially when the rear passengers include elderly people and / or children.

[0024] Reference Figure 1, Figure 1 is a schematic diagram of a driving mode control system of a vehicle according to an embodiment of the present invention.

[0025] A driving mode control system for a vehicle according to an embodiment of the present invention includes an input module 100, a control module 200 and an adjustment module 300. The input module 100 includes a passenger monitoring unit 110, which collects images of passengers through monitoring components such as a passenger status detection camera 111, and the passenger status detection camera 111 transmits the image of the passenger to the passenger monitoring unit 110 through a low voltage differential signal (LVDS). The passenger monitoring unit 110 detects the identity information and status of the passenger based on the collected image, such as the approximate age and gender of the passenger, so as to determine whether the passenger includes an elderly person and / or a child. When it is detected that the passenger includes an elderly person and / or a child, the passenger monitoring unit 110 generates a driving mode adjustment request signal. The control module 200 includes a body controller 210, and the driving mode adjustment request signal generated by the passenger monitoring unit 110 is sent to the body controller 210 through, for example, a CAN bus, and the body controller 210 outputs a driving mode adjustment instruction based on the driving mode adjustment request signal. The driving mode adjustment instruction output by the vehicle body controller 210 is sent to the adjustment module 300 via the CAN bus, and the adjustment module 300 adjusts the current driving mode of the vehicle to a preset driving mode based on the driving mode adjustment instruction. The preset driving mode is, for example, a comfortable riding mode with reduced driving performance.

[0026] In addition, the input module 100 of the present invention also includes a driving mode switch 120, through which the passenger can select the desired driving mode. After receiving the driving mode selected by the passenger, the driving mode switch 120 generates a driving mode adjustment request signal, and transmits the driving mode adjustment request signal to the control module 200 via a wired signal to adjust the driving mode.

[0027] The present invention sets a passenger monitoring unit 110 and a driving mode switch 120 in the input module 100, so that: on the one hand, the driving mode can be adjusted according to the passenger information detected by the passenger monitoring unit 110, and on the other hand, the driving mode selection made by the passenger through the driving mode switch 120 based on the passenger's own needs. Thus, the passenger's riding experience is improved through both automatic selection and manual selection. In addition, since the driving mode switch 120 is set, the driving mode control system of the present invention can also actively select the driving mode through the driving mode switch 120 when the passenger is not identified as an elderly person and / or a child or when the passenger does not include an elderly person and / or a child, thereby further improving the riding comfort.

[0028] In some embodiments, the driving mode switch 120 can be disposed at the front seat backrest or the rear seat armrest of the vehicle. In this way, it is convenient for rear passengers to select the driving mode. It is understood that the installation position of the driving mode switch 120 is not limited thereto and can vary depending on different needs.

[0029] In addition, the driving mode switch 120 can be provided with a normal electric vehicle mode and a comfortable ride mode for passengers to choose. In the normal electric vehicle mode, the driving performance of the vehicle will be maintained at 100% acceleration performance and 100% regenerative braking performance. In the comfortable ride mode, the driving performance of the vehicle can be maintained at less than 80% acceleration performance and less than 80% regenerative braking performance according to the adjustment capability. It should be noted that the driving modes selectable by passengers are not limited to this. According to the adjustment capability of the vehicle, in addition to setting the normal electric vehicle mode, a comfortable ride mode with multiple gears can also be set so that passengers can choose as needed.

[0030] Continue to refer to Figure 1 In this embodiment, the adjustment module 300 may include a vehicle controller 310, and the vehicle controller 310 is configured to adjust the driving performance of the vehicle based on the driving mode adjustment instruction from the body controller 210. Specifically, the vehicle controller 310 coordinates the vehicle's propulsion system 330 through the CAN bus to reduce the vehicle's acceleration performance. In some embodiments, depending on the vehicle's adjustment capability, the propulsion system 330 can adjust the vehicle's acceleration performance to less than or equal to 80% of the acceleration performance. For example, the propulsion system 330 can adjust the vehicle's acceleration performance to 80% or 70% of the acceleration performance. In this way, the driving mode control system of the present invention reduces the acceleration performance of the vehicle, so that passengers will not feel the higher acceleration of the vehicle when riding, thereby improving ride comfort.

[0031] In addition, in the present embodiment, the adjustment module 300 may further include an electronic stability controller (ESC) 320, which is configured to adjust the regenerative braking performance of the vehicle based on the driving mode adjustment instruction from the body controller 210. In some embodiments, the electronic stability controller 320 may adjust the regenerative braking performance of the vehicle to less than or equal to 80% of the regenerative braking performance, depending on the adjustment capability of the vehicle. For example, the electronic stability controller 320 may adjust the regenerative braking performance of the vehicle to 80%, 50% or 0% of the regenerative braking performance. In this way, the driving mode control system of the present invention reduces or even cancels the regenerative braking of the vehicle, so that passengers will not feel the emergency braking of the vehicle when riding, thereby improving the riding comfort.

[0032] It should be pointed out that the configuration of the adjustment module 300 of the present invention is not limited to this, and different adjustment devices can be configured according to vehicle requirements. For example, the adjustment module 300 can also be configured with a device for adjusting the traction of the vehicle, a device for adjusting the body height of the vehicle, etc., so as to improve the stability of the vehicle during driving and improve the riding experience of passengers.

[0033] like Figure 1 As shown, the driving mode control system according to the present invention may also include an output module 400. The body controller 210 may command the output module 400 to send a driving mode adjustment reminder signal to the driver through the CAN bus. The driver chooses whether to adjust the driving mode based on the driving mode adjustment reminder signal. When the driver confirms the adjustment of the driving mode within a preset time period such as 5 seconds or 10 seconds, the output module 400 sends a confirmation adjustment message to the body controller 210. The body controller 210 generates a driving mode adjustment instruction based on the confirmation adjustment message to command the adjustment module 300 to adjust the driving performance of the vehicle. In this way, the driving mode control system of the present invention can also choose whether to change the driving mode according to the driver's demand for the driving performance of the vehicle, so that the adjustment process of the driving mode is safer and more reliable.

[0034] In some embodiments, the output module 400 may include an infotainment controller 410, which sends a driving mode adjustment reminder signal to a terminal device 420 used by the driver based on the driving mode adjustment instruction from the body controller 210. The terminal device 420 may include a central display 421 and a sound device 422. After receiving the driving mode adjustment reminder signal, the terminal device 420 may pop up a text notification such as "Driving mode changed to comfortable riding mode, yes or no" on its central display 421, and / or issue a voice notification of the above content through its sound device 422. Thus, the driver can choose whether to change the driving mode. Alternatively, after the notification pops up on the central display 421, and if the driver does not confirm or reject the driving mode change, the sound device 422 may issue a voice notification to remind the driver to make a choice. In this embodiment, the sound device 422 may be a speaker.

[0035] In some embodiments, after the infotainment controller 410 drives the terminal device 420 to issue a notification on whether to adjust the driving mode, and the terminal device 420 does not issue a confirmation adjustment message within a preset time period, the body controller 210 may automatically generate a driving mode adjustment instruction to adjust the driving mode. In this way, the driving mode may be changed without the driver confirming or rejecting the change of the driving mode.

[0036] Reference Figure 2 , Figure 2 A driving mode control method according to an embodiment of the present invention is shown.

[0037] First, the passenger status detection camera 111 collects images of passengers (step S100 ).

[0038] The passenger monitoring unit 110 determines whether the passengers include elderly persons and / or children based on the acquired images (step S101 ).

[0039] In the case where the passengers include elderly people and / or children, the passenger monitoring unit 110 generates a driving mode adjustment request signal (step S102).

[0040] The passenger monitoring unit 110 sends a driving mode adjustment request signal to the vehicle body controller 210 , and the vehicle body controller 210 outputs a driving mode adjustment instruction based on the driving mode adjustment request signal (step S103 ).

[0041] The vehicle body controller 210 sends the driving mode adjustment instruction to the adjustment module 300 , and the adjustment module 300 adjusts the driving mode of the vehicle to a preset driving mode (step S104 ).

[0042] In step S104, the body controller 210 commands the vehicle controller 310 and the electronic stability controller 320 of the adjustment module 300 to adjust the driving performance of the vehicle based on the driving mode adjustment instruction, wherein the vehicle controller 310 coordinates the propulsion system 330 to reduce the acceleration performance of the vehicle, and the electronic stability controller 320 reduces or cancels the regenerative braking performance of the vehicle.

[0043] In addition, the driving mode control method of the vehicle according to the present invention may also generate a driving mode adjustment request signal based on the driving mode selected by the passenger through the driving mode switch 120 (step S105 ).

[0044] In this way, the present invention controls the vehicle's driving mode from two aspects: the vehicle's autonomous monitoring and the passengers' needs, so that the passengers have a better riding experience.

[0045] Reference Figure 3 , Figure 3 A driving mode control method of a vehicle according to another embodiment of the present invention is shown.

[0046] By comparison Figure 3 and Figure 2 It can be seen that, Figure 3 The method shown is similar to Figure 2The difference between the method shown is that after the body controller 210 outputs a driving mode adjustment instruction based on the driving mode adjustment request signal, the body controller 210 will also send the driving mode adjustment instruction to the infotainment controller 410 of the output module 400, and the infotainment controller 410 generates a driving mode adjustment reminder signal (step S204).

[0047] Based on the driving mode adjustment reminder signal, the infotainment controller 410 drives the terminal device 420 used by the driver to issue a notification on whether to change the driving mode, and the driver makes a choice through the terminal device 420 (step S205).

[0048] If the driver chooses to confirm the adjustment within the preset time period, the terminal device 420 sends a confirmation adjustment message to the body controller 210, and the body controller 210 generates a driving mode adjustment instruction based on the confirmation adjustment message to adjust the driving mode to the preset driving mode (step S207).

[0049] In addition, if the driver does not confirm or reject the adjustment within the preset time, that is, if the body controller 210 does not receive the confirmation adjustment message sent by the terminal device 420 within the preset time, the body controller 210 will automatically generate a driving mode adjustment instruction, thereby adjusting the driving mode to the preset driving mode (step S206).

[0050] The driving mode control system of the present invention helps passengers to automatically or manually select a driving mode by setting a passenger monitoring unit 110 and a driving mode switch 120, thereby obtaining a comfortable riding experience of the vehicle. The control system of the present invention can realize driving mode control by adding a driving mode switch 120 to the existing vehicle configuration, combining software and hardware design, which is cost-effective, has high production efficiency, and can also be applied to a variety of scenarios, such as taxis. In addition, the control system of the present invention is not limited to new energy vehicles, and can also be applied to other types of vehicles such as hybrid vehicles according to needs. Specifically, when applied to hybrid vehicles, the driving mode can be adjusted when the driving mode control system detects that the passengers include the elderly and / or children or according to the needs of the passengers, wherein the driving mode that the passenger can select can be a comfortable riding mode with reduced driving performance, a normal fuel vehicle mode, and a normal electric vehicle mode. In the normal fuel vehicle mode or the normal electric vehicle mode, the acceleration performance of the vehicle can be 100% acceleration performance. In the comfortable riding mode, the driving mode control system can adjust the acceleration performance of the vehicle to less than or equal to 80% acceleration performance, and the passenger will not feel the higher acceleration of the vehicle when riding, thereby improving the riding comfort.

[0051] It should be understood that the embodiments shown in the figures only show optional configurations of the driving mode control system according to the present invention, which are however only illustrative and not restrictive, and other configurations may be adopted without departing from the spirit and scope of the present invention.
