[0033] The various exemplary embodiments, features, and aspects of this disclosure will now be described in detail with reference to the accompanying drawings. Furthermore, numerous specific details are set forth in the following detailed embodiments to better illustrate the invention. Those skilled in the art will understand that the invention can be practiced without certain specific details. In some instances, means well known to those skilled in the art have not been described in detail in order to highlight the spirit of the invention.

[0034] See Figure 1 An embodiment of the present invention provides a method for controlling the rear ambient lighting of a vehicle, comprising the following steps S11 to S12:

[0035] Step S11: Obtain the rear passenger occupancy status information and rear ambient light and music rhythm enable status information detected by the vehicle sensors.

[0036] Specifically, the vehicle-mounted sensors are, for example, any type of sensor installed on the rear seats to detect / sensor whether someone is sitting in the rear seats; for example, a camera and image recognition device to capture images of the rear seats and identify whether someone is sitting in them; for example, a gravity sensor to determine whether someone is sitting in the seat based on the weight borne by the seat; for example, a photoelectric sensor to determine whether someone is sitting in the seat based on the light signal of the rear seat environment, i.e., whether there is any obstruction, as there will be obstruction if someone is sitting in the seat; the above are just examples, and the vehicle-mounted sensors in the embodiments of the present invention are not limited to the above types;

[0037] Among them, in-vehicle ambient lighting has become increasingly popular because it can enhance the entertainment driving atmosphere. Currently, in-vehicle ambient lighting can achieve real-time synchronous brightness changes with the volume and frequency of externally played music, which is the ambient lighting music rhythm function. The method of this embodiment is applied to vehicles equipped with ambient lighting music rhythm function. In step S11, the enabling status of the rear ambient lighting music rhythm function is obtained, that is, whether the driver has activated the rear ambient lighting music rhythm function.

[0038] Step S12: If the rear passenger seating status information is that no one is sitting in the back seat, the rear ambient light music rhythm enable status information is invalid, and the vehicle speed is greater than the first preset vehicle speed threshold or the vehicle driving time is greater than the first preset time, then a first control command is generated, and the rear ambient light of the vehicle is controlled to gradually dim from normal brightness according to the first control command for a second preset time.

[0039] Specifically, when the rear ambient lighting music rhythm enable status information is invalid, it indicates that the driver does not need to use the rear ambient lighting; when the rear passenger seating status information is unoccupied, it indicates that there is no need for rear passenger ambient lighting. Generally, when the vehicle is first started, the rear passenger compartment needs lighting, but when the vehicle is driving steadily, lighting is not needed. Therefore, when the vehicle speed is greater than the first preset speed threshold or the vehicle driving time is greater than the first preset time, it indicates that the vehicle has been driving normally or has been driving for a period of time, and at this time, the rear passenger compartment does not need lighting. At this time, to meet the energy-saving requirements, energy-saving control is required, so a first control command is generated, and the rear ambient lighting of the vehicle is controlled to gradually dim from normal brightness according to the first control command for a second preset time.

[0040] The method of this invention determines whether to perform energy-saving control based on the passenger status of the rear seats, the ambient lighting and music rhythm enable status of the rear seats, and the vehicle speed. If so, a first control command is generated, and the rear ambient lighting is gradually dimmed from its normal brightness for a second preset time according to the first control command. This enables the rear ambient lighting to be turned off gradually when the driver does not need to use it, thereby reducing unnecessary lighting of the rear ambient lighting and reducing power consumption.

[0041] In a specific example, see Figure 2 The method further includes:

[0042] Step S13: After the rear ambient light of the vehicle gradually dims from its normal brightness for a second preset duration, if the vehicle speed decreases to a second preset speed threshold for a third preset duration during driving, a second control command is generated, and the rear ambient light of the vehicle is controlled to gradually brighten back to the normal brightness for a third preset duration according to the second control command.

[0043] Specifically, when the vehicle speed drops to the second preset speed threshold for a third preset time during driving, it indicates that the vehicle may need to stop. In this case, the rear ambient lights of the vehicle are controlled to gradually brighten to the normal brightness over the third preset time.

[0044] In one specific example, step S12 further includes:

[0045] When the rear ambient lighting music rhythm enable status information is valid, the rear ambient lighting of the vehicle is controlled to be lit at the normal brightness.

[0046] Specifically, when the rear ambient lighting music rhythm enable state is effectively activated, it indicates that the driver has a need to use the rear ambient lighting, and therefore no energy-saving control is performed.

[0047] In a specific example, the first preset vehicle speed threshold is greater than the second preset vehicle speed threshold; the first preset duration is greater than the second preset duration and the third preset duration.

[0048] For example, the first preset vehicle speed threshold is preferably, but not limited to, 20 km / h, the second preset vehicle speed threshold is preferably, but not limited to, 5 km / h, the first preset duration is preferably, but not limited to, 3 seconds, the second preset duration is preferably, but not limited to, 2 seconds, and the third preset duration is preferably, but not limited to, 1.7 seconds.

[0049] In a specific example, see Figure 3 The method further includes:

[0050] Step S10: Monitor in real time whether an ambient light energy-saving command input by the driver is received. If an ambient light energy-saving command input by the driver is received, then execute steps S11, S12, and S13. The ambient light energy-saving command is input by the driver through a physical button or by issuing a voice command.

[0051] See Figure 4 Another embodiment of the present invention provides a vehicle rear ambient lighting control system, comprising:

[0052] Information acquisition unit 1 is used to acquire information on the rear passenger occupancy status and the rear ambient lighting and music rhythm enable status detected by the vehicle sensors.

[0053] The first control unit 2 is configured to generate a first control command if the rear passenger occupancy status information is that no one is riding in the vehicle, the rear ambient light music rhythm enable status information is invalid, and the vehicle speed is greater than a first preset vehicle speed threshold or the vehicle travel time is greater than a first preset time. Then, the control unit 2 controls the rear ambient light of the vehicle to gradually dim from its normal brightness for a second preset time according to the first control command.

[0054] In a specific example, see Figure 5 The system also includes:

[0055] The second control unit 3 is used to generate a second control command after the rear ambient light of the vehicle gradually dims from its normal brightness for a second preset time. If the vehicle speed decreases to a second preset speed threshold for a third preset time during driving, the control unit 3 controls the rear ambient light of the vehicle to gradually brighten back to the normal brightness for a third preset time according to the second control command.

[0056] In one specific example, the first control unit 2 is further configured to:

[0057] When the rear ambient lighting music rhythm enable status information is valid, the rear ambient lighting of the vehicle is controlled to be lit at the normal brightness.

[0058] In a specific example, the first preset vehicle speed threshold is greater than the second preset vehicle speed threshold; the first preset duration is greater than the second preset duration and the third preset duration.

[0059] In a specific example, see Figure 6 The system also includes:

[0060] The instruction receiving unit 4 is used to monitor in real time whether an ambient light energy-saving instruction input by the driver is received. If an ambient light energy-saving instruction input by the driver is received, the rear ambient light control system of the vehicle is activated, so that the information acquisition unit, the first control unit, and the second control unit work. The ambient light energy-saving instruction is input by the driver through physical buttons or by issuing a voice command.
