Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0034] In order to solve the problem that the vehicle ambient light in the prior art lacks the ability to respond to complex operations during driving and has limited effect on improving the driver's driving pleasure. The present invention provides an ambient light control method based on driving operations, which collects accelerator pedal information and brake pedal information respectively through a central domain controller and a brake controller, collects information in the central domain controller and combines it with a preset mapping table to obtain the target display state of the ambient light, and 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, so that the real-time display state of the ambient light is consistent with the target display state. On the whole, it can respond to the driver's acceleration and deceleration driving operations 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, and improve the driver's driving pleasure. The central domain controller performs the main data processing, with fast response speed and high processing accuracy, which can effectively ensure the real-time interaction between the ambient light and the driving operation and ensure the interactive effect.

[0035] For details, please refer to Figure 1 and Figure 2 This application mainly uses the vehicle's central domain controller 10 and brake controller 20 to implement data collection and processing tasks. The regional controller 30 is mainly used to forward the data of the target display status obtained after processing by the central domain controller 10 to the atmosphere light driver 40. The atmosphere light driver 40 drives the atmosphere light 41 according to the data information in the target display status, so that the actual display state of the atmosphere light 41 is consistent with the target display state.

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

[0037] Step S01: The accelerator pedal information and the brake pedal information are collected through the central domain controller and the brake controller respectively, and the brake pedal information is sent to the central domain controller.

[0038] Step S02: obtaining a target display state of the ambient light by combining the accelerator pedal information and the brake pedal information through a mapping table preset in the central domain controller, wherein the target display state includes display color, display frequency and display brightness.

[0039] Step S03: forwarding the target display state to the atmosphere light driver through the zone controller, so that the display state of the atmosphere light is controlled by the atmosphere light driver according to the target display state, so that the real-time display state of the atmosphere light is consistent with the target display state.

[0040] In step S01, the accelerator pedal information includes the accelerator pedal travel change rate, and the brake pedal information includes the brake pedal travel change rate, so that the accelerator pedal travel change rate is used as an acceleration reference, and the brake pedal travel change rate is used as a deceleration reference, so that the display state of the ambient light can match the driver's acceleration and deceleration operations.

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

[0042] In this embodiment, the ambient light is an RGB three-color integrated light. When the ambient light is enabled, it generally has an initial display state. The initial display state is, for example, a white constant. In this initial display state, the mapping relationship of the mapping table includes: when the accelerator pedal travel 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 travel change rate is greater than zero, the blue channel value of the display color is increased to the corresponding preset value.

[0043] Among them, the greater the accelerator pedal travel change rate and the brake pedal travel change rate, the greater the corresponding preset value, that is, the final display color of the ambient light is also related to the size of the accelerator pedal travel change rate and the brake pedal travel change rate.

[0044] To further enhance the difference in atmosphere at different acceleration levels, in this embodiment, the mapping relationship of the mapping table also includes: when the accelerator pedal travel change rate is greater than a first threshold value, the mapping value of the display frequency is the first frequency, otherwise it is the second frequency, and the first frequency is less than the second frequency; when the accelerator pedal travel change rate is greater than the first threshold value, the brightness range of the display brightness is the first range, otherwise it is the 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 travel change rate, the greater the display brightness.

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

[0046] Correspondingly, when the rate of change of the accelerator pedal travel is greater than the first threshold, corresponding to high acceleration, a flashing frequency of 10 Hz is easily perceived by humans, and a higher brightness mapping slope is used, which has a strong photosensitivity stimulation to the driver, indicating that the current state is in high-acceleration driving. The atmosphere provided is relatively tense, which matches the current driving behavior to a high degree. The tense atmosphere stimulation can prompt the driver to increase the secretion of adrenaline (within a safe range), increase the driver's excitement within a safe range, and enhance the perception of the driving environment and road environment, thereby improving safety under high-acceleration driving that is prone to dangerous conditions.

[0047] When the rate of change of the accelerator pedal travel is less than the first threshold, corresponding to a lower acceleration, a flashing frequency of 30 Hz can be effectively perceived by humans. At the same time, a lower brightness mapping slope is used, and the photosensitive stimulation to the driver is weak, indicating that the current state is a lower acceleration driving state. Compared with the high acceleration atmosphere, it is relatively peaceful and more suitable for safer acceleration methods. While ensuring that the ambient light can provide a certain atmosphere effect, the interference of the stimulation of the ambient light on driving safety can be reduced, thereby ensuring driving safety.

[0048] To further enhance the difference in atmosphere at different deceleration and braking levels, in this embodiment, the mapping relationship of the mapping table also includes: when the brake pedal stroke change rate is greater than the second threshold, the mapping value of the display frequency is the third frequency, otherwise it is the fourth frequency, and 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 the third range, otherwise it is the 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 travel of the brake pedal, the timing unit is seconds, the third frequency is 10 Hz, the fourth frequency is 30 Hz, the third range of display brightness is 50% to 100% of the maximum brightness, and the fourth range of display brightness is 50% to 75% of the maximum brightness. The atmosphere effect provided is similar to the relationship between the acceleration magnitude and the atmosphere effect, which will not be repeated here.

[0050] In this 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, the partial mapping relationship of acceleration and braking is the same, and the display brightness and frequency atmosphere are the same under high acceleration and high deceleration, and the display brightness and frequency atmosphere are the same under low acceleration and low deceleration. When accelerating driving, the display color is reddish, and when decelerating driving, the display color is bluish, which can effectively distinguish between accelerating driving and decelerating driving.

[0051] In some cases, high-acceleration driving is generally accompanied by high-deceleration driving behavior. For example, in racing, both acceleration and deceleration are high. When driving, the ambient light can maintain the same strobe and similar brightness. When switching between acceleration and deceleration, the display color bias is switched to effectively display the acceleration and deceleration switching, enhance the atmosphere, and increase the driving interest.

[0052] In emergency situations, the ambient light provides a more stimulating atmosphere for emergency braking, which can enhance the driver's ability to deal with emergency situations and improve driving safety.

[0053] Corresponding to the conventional uniform speed running behavior, the mapping relationship of the mapping table also 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%, the frequency can be set to 0 or greater than 60Hz, providing a flicker-free display effect, or using a low-frequency cyclic breathing display method.

[0054] The present application also provides a vehicle, including: an ambient light, a central domain controller, a brake controller, a regional controller and an ambient light driver, wherein the central domain controller, the brake controller and the regional controller are communicatively connected via a CAN bus.

[0055] The central domain controller and the brake controller are used to collect accelerator pedal information and brake pedal information respectively, and the brake controller is used to send the brake pedal information to the central domain controller;

[0056] The central domain controller is further used to obtain a target display state of the ambient light by combining the accelerator pedal information and the brake pedal information through a mapping table preset in the central domain controller, the target display state including display color, display frequency and display brightness;

[0057] The central domain controller is also used to forward the target display status to the ambient light driver through the regional controller;

[0058] The ambient light driver is used to control the display state of the ambient light according to the target display state, so that the real-time display state of the ambient light is consistent with the target display state.

[0059] In this embodiment, the accelerator pedal information includes the accelerator pedal travel change rate, and the brake pedal information includes the brake pedal travel change rate, so as to characterize the vehicle acceleration according to the accelerator pedal travel change rate, and characterize the vehicle deceleration according to the brake pedal travel change rate, thereby obtaining the driver's driving operation, and then the display state of the ambient light can be matched with the driver's driving operation, thereby improving the atmosphere creation effect.

[0060] The driving operation-based ambient light control method and vehicle provided in the present application can respond to the driver's acceleration and deceleration driving operations in real time, automatically control the display status of the ambient light in real time, realize the interaction between the ambient light and the driving operation, and enhance the driver's driving pleasure. The central domain controller is used for major data processing, with fast response speed and high processing accuracy, which can effectively ensure the real-time interaction between the ambient light and the driving operation and ensure the interactive effect.

[0061] Moreover, through automatic atmosphere control, it can not only avoid the danger of distracted driving caused by actively adjusting the atmosphere lights, but also have the effect of refreshing the mind and resisting fatigue. It can, to a certain extent, enhance the driver's perception of the changing environment and the ability to deal with emergency situations, thereby improving driving safety.
