[0034] To solve the problem that the ambient light of the prior art vehicle lacks the response ability to the complex operation in driving and has limited effect on improving the driving pleasure of the driver. The present application provides a driving operation based ambient light control method, which collects the accelerator pedal information and the brake pedal information through the central domain controller and the brake controller respectively, obtains the target display state of the ambient light in the central domain controller combined with the preset mapping table, then forwards the target display state to the ambient light driver through the regional controller, and drives the ambient light through the ambient light driver to make the real-time display state of the ambient light consistent with the target display state. Overall, it can respond to the acceleration and deceleration driving operation of the driver in real time, automatically control the display state of the ambient light in real time, realize the interaction between the ambient light and the driving operation, improve the driving pleasure of the driver, and use the central domain controller for main data processing, which has fast response speed and high processing precision, can effectively guarantee the real-time interaction between the ambient light and the driving operation, and guarantee the interaction effect.

[0035] In particular, with reference to Figure 1 and Figure 2 , the application mainly uses the central domain controller 10 and the brake controller 20 to realize the data acquisition and processing task, and the area controller 30 is mainly used to forward the data of the target display state obtained after the central domain controller 10 processes to the atmosphere lamp driver 40, and drive the atmosphere lamp 41 according to the data information in the target display state through the atmosphere lamp driver 40, so that the actual display state of the atmosphere lamp 41 is consistent with the target display state.

[0036] In this embodiment, the control method comprises:

[0037] Step S01: Collecting the accelerator pedal information and the brake pedal information through the central domain controller and the brake controller respectively, and sending the brake pedal information to the central domain controller.

[0038] Step S02: Obtaining the target display state of the atmosphere lamp through the preset mapping table in the central domain controller, combining the accelerator pedal information and the brake pedal information, the target display state including display color, display frequency and display brightness.

[0039] Step S03: Forwarding the target display state to the atmosphere lamp driver through the area controller, so as to control the display state of the atmosphere lamp according to the target display state through the atmosphere lamp driver, so that the real-time display state of the atmosphere lamp is consistent with the target display state.

[0040] In step S01, the accelerator pedal information includes the accelerator pedal stroke change rate, and the brake pedal information includes the brake pedal stroke change rate, so that the display state of the atmosphere lamp can match the acceleration and deceleration operation of the driver by taking the accelerator pedal stroke change rate as the acceleration reference and the brake pedal stroke change rate as the deceleration reference.

[0041] The brake controller 20 and the central domain controller 10 communicate through the CAN bus, which can realize real-time transmission of data, ensure the real-time transmission of brake pedal information to the central domain controller 10, and further ensure the real-time adjustment of the atmosphere lamp and the interactive effect of the atmosphere lamp and the driving behavior.

[0042] In this embodiment, the atmosphere lamp is an RGB three-color integrated lamp, and when the atmosphere lamp is enabled, it generally has an initial display state, such as white constant, etc. In the initial display state, the mapping relationship of the mapping table includes: when the accelerator pedal stroke change rate is greater than zero, the red channel value of the display color is increased to the corresponding preset value; when the brake pedal stroke change rate is greater than zero, the blue channel value of the display color is increased to the corresponding preset value.

[0043] The greater the accelerator pedal stroke change rate and brake pedal stroke change rate, the greater the preset value, that is, the final display color of the atmosphere lamp is also related to the size of the accelerator pedal stroke change rate and brake pedal stroke change rate.

[0044] To further distinguish the atmosphere of different acceleration degrees, in the embodiment, the mapping relationship of the mapping table further includes: when the accelerator pedal stroke change rate is greater than a first threshold, the mapping value of the display frequency is a first frequency, otherwise, the mapping value of the display frequency is a second frequency, the first frequency is less than the second frequency; when the accelerator pedal stroke change rate is greater than the first threshold, the brightness range of the display brightness is a first range, otherwise, the brightness range of the display brightness is a second range, the starting brightness of the first range and the second range is the same, the ending brightness of the first range is greater than the ending brightness of the second range, and the greater the accelerator pedal stroke change rate, the greater the display brightness.

[0045] In a specific example, the first threshold is 50% of the total stroke of the accelerator pedal, the timing unit is second, the first frequency is 10 Hz, the second frequency is 30 Hz, the first range of the display brightness is 50% to 100% of the maximum brightness, and the second range of the display brightness is 50% to 75% of the maximum brightness.

[0046] Correspondingly, when the accelerator pedal stroke change rate is greater than the first threshold, corresponding to high acceleration, the flashing frequency of 10 Hz is easy to be perceived by humans, and at the same time, a higher brightness mapping slope is adopted, the light stimulation to the driver is strong, indicating that the current is in a high acceleration driving state, and a relatively tense atmosphere is provided, which has a high matching degree with the current driving behavior, and through the stimulation of the relatively tense atmosphere, the secretion of adrenaline of the driver can be increased (within a safe range), the excitement of the driver can be increased within a safe range, the perception ability to the driving environment and road environment can be improved, and thus the safety under high acceleration driving which is easy to encounter dangerous conditions can be improved.

[0047] When the accelerator pedal stroke change rate is less than the first threshold, corresponding to low acceleration, the flashing frequency of 30 Hz can be effectively perceived by humans, and at the same time, a lower brightness mapping slope is adopted, the light stimulation to the driver is weak, indicating that the current is in a low acceleration driving state, and compared with the atmosphere of high acceleration, the atmosphere is more peaceful, which is more suitable for a safer acceleration mode, under the condition that the atmosphere lamp can provide a certain atmosphere effect, the interference of the stimulation of the atmosphere lamp to the driving safety can be reduced, and the driving safety can be ensured.

[0048] To further enhance the atmosphere difference of different deceleration braking degrees, in the embodiment, the mapping relationship of the mapping table further includes: when the brake pedal stroke change rate is greater than the second threshold, the mapping value of the display frequency is a third frequency, otherwise, a fourth frequency, the third frequency is less than the fourth frequency; when the brake pedal stroke change rate is greater than the second threshold, the brightness range of the display brightness is a third range, otherwise, a fourth range, the starting brightness of the third range and the fourth range is the same, the ending brightness of the third range is greater than the ending brightness of the fourth range, and the greater the brake pedal stroke change rate, the greater the display brightness.

[0049] In a specific example, the second threshold is 50% of the total stroke of the brake pedal, the timing unit is second, the third frequency is 10Hz, the fourth frequency is 30Hz, the third range of the display brightness is 50% to 100% of the maximum brightness, and the fourth range of the display brightness is 50% to 75% of the maximum brightness. The atmosphere effect provided is similar to the relationship between the acceleration size and the atmosphere effect described above, which will not be repeated here.

[0050] In the embodiment, the first threshold and the second threshold are the same, the first frequency and the third frequency are the same, the second frequency and the fourth frequency are the same, the first range and the third range are the same, and the second range and the fourth range are the same. That is, part of the mapping relationship of acceleration and braking is the same, the same display brightness and frequency atmosphere is provided under high acceleration and high deceleration, the same display brightness and frequency atmosphere is provided under low acceleration and low deceleration, the display color is biased red during acceleration driving, the display color is biased blue during deceleration driving, and the acceleration driving and deceleration driving can be effectively distinguished.

[0051] In some cases, during high acceleration driving, high deceleration driving behavior is generally accompanied, for example, in racing sports, both the acceleration and the deceleration are high, during driving, the atmosphere lamp can maintain the same frequency flashing and similar brightness, and by switching the display color bias during acceleration and deceleration switching, the acceleration and deceleration switching can be effectively shown, the atmosphere feeling is improved, and the driving interest is improved.

[0052] In an emergency situation, the atmosphere lamp provides a more stimulating atmosphere corresponding to the emergency braking behavior, which can improve the handling ability of the driver in the emergency situation and improve the driving safety.

[0053] Corresponding to the conventional uniform speed running behavior, the mapping relationship of the mapping table further includes: when the accelerator pedal stroke change rate and the brake pedal stroke change rate are both zero, the display color is kept white, the display brightness is 50%, and the frequency can be set to 0 or greater than 60Hz, providing a no-flashing display effect, or a low-frequency breathing display mode is adopted.

[0054] The application also provides a vehicle, comprising an atmosphere lamp and a central domain controller, a brake controller, a region controller and an atmosphere lamp driver, wherein the central domain controller, the brake controller and the region controller are connected through a CAN bus.

[0055] The central domain controller and the brake controller are respectively used for collecting accelerator pedal information and brake pedal information, and the brake controller is used for sending the brake pedal information to the central domain controller.

[0056] The central domain controller is also used for obtaining a target display state of the atmosphere lamp by combining the accelerator pedal information and the brake pedal information through a preset mapping table in the central domain controller, and the target display state comprises a display color, a display frequency and a display brightness.

[0057] The central domain controller is also used for forwarding the target display state to the atmosphere lamp driver through the region controller.

[0058] The atmosphere lamp driver is used for controlling a display state of the atmosphere lamp according to the target display state, so that the real-time display state of the atmosphere lamp is consistent with the target display state.

[0059] In the embodiment, the accelerator pedal information comprises an accelerator pedal stroke change rate, and the brake pedal information comprises a brake pedal stroke change rate, so as to represent vehicle acceleration according to the accelerator pedal stroke change rate and vehicle deceleration according to the brake pedal stroke change rate, thereby obtaining the driving operation of the driver, and further matching the display state of the atmosphere lamp with the driving operation of the driver, and improving the atmosphere creating effect.

[0061] Moreover, through the automatic atmosphere regulation and control, the distraction caused by the active regulation of the atmosphere lamp can be avoided, the refreshing effect and the anti-fatigue effect can be achieved, the perception ability of the driver to the changing environment can be improved to a certain extent, the processing ability of the driver to the emergency situation can be improved, and the driving safety can be improved.
