The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
It will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or be connected to the other element through intervening elements. Further, "connection" in the following embodiments is understood to mean "electrical connection", "communication connection", or the like, if there is a transfer of electrical signals or data between the connected objects.
As described in the background, the prior art automotive rear combination lamp products are functionally simple, support the illumination of basic legislative item functions, have almost no diagnostic function, no control unit, and no other intelligent applications. However, with the technical progress of automobile informatization and intellectualization, the functions of the rear combination lamp can be better utilized, the technological degree is improved, the driving safety is improved, and the individual requirements are met.
For the above reasons, please refer to fig. 1, in an embodiment of the present application, a rear combination lamp control device 100 is provided, which includes an emergency braking signal obtaining module 10 and a control module 20, wherein the emergency braking signal obtaining module 10 is electrically connected to the control module 20. The emergency braking signal acquisition module 10 is used for acquiring an emergency braking signal, the control module 20 is used for controlling the rear combination lamp of the vehicle to execute a preset emergency braking action according to the emergency braking signal, and the emergency braking signal comprises at least one of a first emergency braking signal used for indicating that the acceleration value of the whole vehicle is less than or equal to a first preset threshold value, an anti-lock braking working signal and a braking lamp 11 signal from the vehicle body controller. The Anti-lock Braking System is called ABS for short. The function is that when the automobile brakes, the braking force of the brake is automatically controlled, so that the wheels are not locked and are in a state of rolling and sliding (the sliding rate is about 20 percent) to ensure that the adhesive force between the wheels and the ground is at the maximum.
As an example, continuing to refer to fig. 1, the emergency brake signal acquisition module 10 is configured to enable the rear combination lamp control device 100 to accurately and effectively acquire the emergency brake signal, so that the control module 20 can perform a preset action according to the signal. For example, the acceleration value and the anti-lock brake working signal of the automobile are collected, the brake lamp 11 is timely turned on according to the emergency braking mode through calculation and judgment, no additional device or part is added, and the comprehensive cost is low. And in addition, the intellectualization of the rear combination lamp of the vehicle is facilitated, the potential safety hazard caused by delay is avoided, and the driving safety is improved.
As an example, with continuing reference to fig. 1, in an embodiment of the present application, the predetermined emergency braking action includes flashing the brake lamp 11 in the rear combination lamp at a predetermined frequency and increasing the current for driving the brake lamp 11, so that the brightness of the brake lamp 11 reaches the upper limit of the regulation. The luminous intensity in the direction of the reference axis of the stop lamp 11 is strictly defined, and the maximum value of class S1 for two or more lamps is 260 candela. So that the brake lamp 11 in the emergency braking state flickers or the brightness is obviously different from that in the general braking state, and the automobile is different from the ordinary brake lamp 11 so as to better remind the rear automobile that the front automobile is in the emergency braking state, so that the rear automobile can be braked or avoided in time.
By way of example, continuing to refer to fig. 1, in one embodiment of the present application, the control module 20 is further configured to: and if the obtained whole vehicle acceleration value is greater than the first preset threshold value and an anti-lock brake non-working signal is obtained, controlling the rear combination lamp to stop executing a preset emergency braking action so as to reduce energy consumption when the vehicle is not in an emergency braking state.
Specifically, in the vehicle rear combination lamp control device 100 in the above embodiment, the first preset threshold is an emergency braking threshold; the emergency braking threshold value is the acceleration of the whole vehicle during the period that the vehicle is positioned on a flat road surface and the tread depth of a brake pedal is a second preset threshold value, and the second preset threshold value is 85% -95%. For example, in some embodiments, the second preset threshold may be 85%, 90%, or 95%. So as to judge whether the vehicle is in a braking state and an emergency braking state, and distinguish a general braking state from an emergency braking state.
As an example, please refer to fig. 2, in an embodiment of the present application, the rear combination vehicle lamp control device further includes an image acquisition unit 30, and the image acquisition unit 30 is connected to the control module 20 and is configured to acquire tunnel information within a preset distance range in front of the vehicle;
the control module 20 is further configured to: under the condition that the position lamp 31 and the outline marker lamp 32 in the rear combination lamp are not lighted, the rear combination lamp is controlled to execute a preset tunnel mode action according to the tunnel information, so that when a vehicle is about to enter a tunnel, the rear vehicle is reminded in advance and the position information is displayed in time, potential safety hazards caused by delay are avoided, and driving safety is improved.
Referring to fig. 3 as an example, in an embodiment of the present application, the image capturing unit 30 includes at least one of a front camera 33 and a telematics terminal 34; and/or the preset tunnel mode action comprises that the position lamp 31 and the outline marker lamp 32 in the vehicle rear combined lamp are both lighted. For example, in some embodiments, the front camera 33 is set to send out a tunnel signal when a tunnel appears 200m ahead of the vehicle; or when it is set that there is a tunnel 200m ahead of the navigation recognition, the in-vehicle information terminal 34 sends a tunnel signal. So that before the vehicle got into the tunnel, open position lamp 31 and marker lamp 32 in advance, light was dark after can solving and getting into the tunnel through sunshine rainfall sensor perception among the traditional art, and the delay of bringing is lighted through automobile body controller control position lamp 31 and marker lamp 32, avoids consequently postponing the potential safety hazard of bringing, improves and drives the security.
As an example, referring to fig. 4, in an embodiment of the present application, the rear combination lamp control device 100 further includes a light intensity sensor 40 connected to the control module 20 for collecting light intensity within a preset distance range around the vehicle; the control module 20 is further configured to: and if the light intensity is greater than or equal to the preset light intensity threshold value, controlling the rear combination lamp to stop executing the preset tunnel mode action, so that the preset tunnel mode action is closed in time when the vehicle leaves the tunnel, and the energy is saved.
