Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Unless defined otherwise, all technical terms used in the examples of the present application have the same meaning as commonly understood by one of ordinary skill in the art. In this application, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
A start switch (ignition switch) is one of the most important switches on a vehicle body, and is mainly used to control an ignition circuit, thereby starting an engine. Backlights are light sources that illuminate an electronic device from the side or back. In the related art, either the backlight is not provided at the start switch of the vehicle body, or the lighting mode of the backlight at the start switch is single. In order to more intuitively transmit the change information of the vehicle state to the driver and improve the technological sense of the whole vehicle body, the embodiment of the application provides a backlight control method, the backlight is applied to a starting switch of the vehicle, as shown in fig. 1, the method comprises the following steps:
Considering that the brightness of the backlight should be adapted to the current light intensity in the vehicle, so that the brightness of the backlight is in accordance with the actual requirement, in the embodiment of the present application, a sensor for detecting the light intensity, such as an ambient light sensor, a light sensor (brightness sensor), etc., may be disposed at a preset position of the vehicle, such as above a front windshield of the vehicle, and the sensor may acquire the light intensity in the vehicle in real time.
And step 102, determining the current contextual model of the vehicle based on the light intensity.
After the light intensity in the current vehicle is obtained, the scene mode where the current vehicle is located can be determined based on the light intensity. There may be multiple types of profiles, and differences in light intensity may result in different profiles for the vehicle.
In the embodiment of the present application, the scene mode may include a day mode and a black day mode, and it should be noted that "day" and "black day" herein do not generally mean that the color of the day is early or late, but mean the brightness of the environment inside the vehicle. In some scenarios, the vehicle is currently in the daytime from a time point of view, but is in a dark day mode based on the brightness level of the interior of the vehicle, for example, when the vehicle passes through a tunnel in the daytime, the daytime from a time point of view, but when the vehicle passes through the tunnel, the light intensity of the interior of the vehicle is weak, and the vehicle is in the dark day mode. In other situations, the vehicle is in the evening (near the dark day) from the time point of view, but the vehicle is in the daytime mode based on the brightness of the interior of the vehicle. The dark day mode and the daytime mode may be switched in real time according to the intensity of light inside the vehicle.
Optionally, in this embodiment of the application, it may be determined whether the current contextual model is the daytime model or the dark day model based on a magnitude relationship between a preset light intensity threshold and the current light intensity inside the vehicle. If the light intensity in the current vehicle is larger than or equal to the light intensity threshold value, determining that the current contextual model of the vehicle is the daytime model; and if the current light intensity in the vehicle is smaller than the light intensity threshold value, determining that the current contextual model of the vehicle is a black day model.
And 103, acquiring the current vehicle state and the current lighting mode of the backlight.
The current vehicle state and the current lighting mode of the backlight are acquired so as to switch the lighting mode of the backlight subsequently based on the two.
And 104, when the current lighting mode and the vehicle state of the backlight meet preset conditions, selecting a target lighting mode from the lighting modes corresponding to the scene mode based on the vehicle state and the current lighting mode, and switching the backlight from the current lighting mode to the target lighting mode.
In the embodiment of the present application, the contextual model output device of the vehicle may output a contextual model in which the vehicle is currently located, the determination device may determine whether the current vehicle state and the current lighting mode of the backlight satisfy preset conditions, and the vehicle body control device, for example, the ECU may select a corresponding target lighting mode from the lighting modes corresponding to the contextual model in which the vehicle is currently located and switch the backlight from the current lighting mode to the target lighting mode when the current vehicle state and the current lighting mode of the backlight satisfy the preset conditions. The above devices may communicate via a CAN network.
The backlight lamp control method provided by the embodiment of the application determines the current contextual model of the vehicle based on the illumination intensity of the current vehicle, and then selects the target lighting mode from the lighting modes corresponding to the contextual model based on the vehicle state and the current lighting mode when the current lighting mode of the backlight lamp and the current vehicle state meet the preset conditions. The control method considers a plurality of factors of the light intensity in the vehicle, the vehicle state and the current lighting mode of the backlight, and reasonably switches the lighting mode of the backlight based on the actual situation, thereby improving the driving experience of the driver.
As an example, the correspondence relationship of the current lighting mode of the backlight in different scene modes, the vehicle state, and the target lighting mode may be stored in the vehicle body control device. Therefore, when the lighting mode of the backlight is switched, the target lighting mode corresponding to the current vehicle state and the current lighting mode of the backlight can be found from the correspondence relationship in the current scene mode, and the backlight can be switched from the current lighting mode to the target lighting mode. For example, the vehicle body control device may store a preset correspondence relationship as shown in table 1, for example, when the current lighting mode of the acquired backlight is B3 and the current vehicle state is C3, then the target lighting mode may be determined to be D3 based on the preset correspondence relationship shown in table 1. Wherein the vehicle state C1' may be the same as or different from the vehicle state C1; the current lighting mode B1 is different from the current lighting mode B1'; the target lighting pattern D1 is different from the target lighting pattern D1'.
TABLE 1
Table 1 shows only two profiles a1 and a2, it being understood that more profiles A3, a4 … …, etc. may be provided for more precise control of the backlight. The various types of profiles described above may be determined based on setting a plurality of light intensity thresholds.
Each of the plurality of profiles may correspond to a respective lighting pattern, and the lighting patterns corresponding to the plurality of profiles are different in order to show the difference between the plurality of profiles. The above difference may be embodied as a difference in brightness of the lighting modes corresponding to different scene modes, for example, the scene mode a corresponds to three lighting modes B1, B2, and B3, the scene mode B corresponds to three lighting modes B1 ', B2', and B3 ', and B1 and B1', B2 and B2 ', and B3 and B3' differ only in brightness from each other. The above-mentioned difference may also be embodied as different types and numbers of lighting modes corresponding to different scene modes, for example, scene mode C corresponds to two lighting modes B11, B22, and scene mode D corresponds to three lighting modes B1 ', B2', and B3 ', where B11 and B22 are different from any one of B1', B2 ', and B3'. Of course, other settings may be performed on the type of the profile and the lighting mode type corresponding to each profile, and the embodiment of the present application is not limited thereto.
As an example, in a case where the contextual models include a daytime model and a dark day model, each of the contextual models corresponds to four lighting modes of a breathing mode, a first normally on mode, a second normally on mode, and a blanking mode. Besides the extinguishing mode, the brightness of each lighting mode in the daytime mode is greater than that of the same lighting mode in the dark day mode, namely the brightness of the first normally-bright mode in the daytime mode is greater than that of the first normally-bright mode in the dark day mode, and the description is omitted.
Optionally, in this embodiment of the application, when the current vehicle state and the current lighting mode of the backlight satisfy a preset condition, selecting a target lighting mode from lighting modes corresponding to the current contextual model based on the vehicle state and the current lighting mode, and switching the backlight from the current lighting mode to the target lighting mode includes:
when the current lighting mode of the backlight is the off mode, and the vehicle state satisfies one of the following conditions: when the door of the vehicle is changed from a closed state to an open state or when the power mode of the starting switch is switched, a breathing mode is selected as a target lighting mode from lighting modes corresponding to the current scene mode, and the backlight lamp is switched from a lighting-off mode to a breathing mode.
It should be noted that the start switch of the vehicle generally includes three modes, LOCK, ON and ACC, and the start switch is switched in the sequence of LOCK-ON-ACC every time the switch is pressed. The power mode of the starting switch is switched every time the starting switch is pressed.
The above setting is explained below with reference to a specific application scenario:
situation one
When the user opens the door of the vehicle in the locked state from outside the vehicle and intends to drive the vehicle, the vehicle is in the key-off state, and therefore it can be understood that the current lighting mode of the backlight is the key-off mode. In this case, when it is determined that the door is turned on from off, the backlight is switched from off to on. The user's gaze can be quickly positioned to the position of the start switch by the flickering of the backlight, thereby improving the driving experience.
In this embodiment, the vehicle door may be a vehicle door corresponding to a main driver seat. When the door corresponding to the main driver seat is opened, the probability that the user intends to drive the vehicle is high, and at the moment, the backlight lamp at the starting switch is switched from the extinguishing mode to the breathing mode, so that the sight of the user can be quickly positioned to the position of the starting switch, and the driving experience is improved. Of course, the door may be any door of the vehicle body.
Situation two
The user drives to a place and puts off the vehicle, and then intends to rest on the vehicle. In order to avoid wasting electric energy, the backlight lamp is switched to the extinguishing mode after a period of time. After the user has finished resting, when intending to start again and ignite the vehicle, the power mode of the starting switch can be switched, at the moment, the backlight is changed from the extinguishing mode to the breathing mode, so that the information that the power mode is switched is fed back to the user, meanwhile, the atmosphere in the vehicle can be improved due to the ignorance of the backlight, and the technological sense of the vehicle body is improved.
Optionally, in this embodiment of the application, when the current vehicle state and the current lighting mode of the backlight satisfy a preset condition, selecting a target lighting mode from lighting modes corresponding to the current contextual model based on the vehicle state and the current lighting mode, and switching the backlight from the current lighting mode to the target lighting mode includes:
when the current lighting mode of the backlight lamp is a breathing mode, and when the mobile device carried by the user is matched with the vehicle, the gear of the vehicle is P gear or N gear, and the brake is pressed down, selecting a second normal lighting mode as a target lighting mode from the lighting modes corresponding to the current contextual model, and switching the backlight lamp from the breathing mode to the second normal lighting mode.
When the current lighting mode of the backlight lamp is the second constant lighting mode and when the brake is released, selecting a breathing mode as a target lighting mode from the lighting modes corresponding to the current scene mode, and switching the backlight lamp from the second constant lighting mode to the breathing mode.
The above setting is explained below with reference to a specific application scenario:
scene three
Referring to the above scenario one, when the user opens the door from outside the vehicle to intend to drive the vehicle, the backlight is switched from the extinction mode to the breathing mode. When a user starts a vehicle, before a starting switch is pressed, the brake is usually pressed down, a vehicle body system can identify mobile equipment carried by the user for identifying whether the identity of the user entering the vehicle is legal or not, when the mobile equipment is matched with the vehicle and the gear of the vehicle is N gear or P gear, the user can be determined to be legal (namely illegal persons such as illegal vehicle stealing persons) and the vehicle is in a non-starting state, and under the precondition that the vehicle can be successfully ignited by pressing the starting switch while the brake is pressed down. At this time, if it is detected that the brake is pressed, the backlight is switched from the breathing mode to the second normal lighting mode (with a higher brightness). The change of the state of the backlight can be intuitively reflected by switching the backlight from a flickering state (namely a breathing mode) to a brighter state (namely a second normally-on mode), so that a user can know that the current brake is effectively stepped on through the change of the backlight, and further can perform the next operation, namely pressing a starting switch to start an engine of a vehicle.
After the vehicle is successfully started, the user releases the brake, and if the brake is released, the backlight lamp is switched from the second normally-on mode to the breathing mode to change the state of the backlight lamp, so that the user can know that the current brake is released through the change of the backlight lamp.
It should be noted that, in order to prevent the vehicle from accidental situations such as vehicle fleeing and vehicle slipping during ignition, the automatic car-blocking type is usually designed such that the ignition must be applied to the brake, and the ignition cannot be successfully started without applying the brake. And the automatic transmission type must be in P gear or N gear at the time of ignition.
Optionally, in this embodiment of the application, when the current vehicle state and the current lighting mode of the backlight satisfy a preset condition, selecting a target lighting mode from lighting modes corresponding to the current contextual model based on the vehicle state and the current lighting mode, and switching the backlight from the current lighting mode to the target lighting mode includes:
when the current lighting mode of the backlight is a breathing mode, and the vehicle state satisfies one of the following conditions: when the vehicle is started successfully or in a non-flameout state, the breathing cycle of the backlight reaches a preset number, a first normally-on mode is selected as a target lighting mode from lighting modes corresponding to the current scene mode, and the backlight is switched to the first normally-on mode from the breathing mode.
It should be noted that the successful start refers to the successful ignition of the vehicle, that is, the engine is in a starting state, and the vehicle enters a non-flameout state after being successfully started.
The above setting is explained below with reference to a specific application scenario:
scene four
Referring to the third scenario, when the user starts the vehicle from the outside of the vehicle and intends to drive the vehicle, the backlight is switched from the off mode to the breathing mode, and then when the brake is pressed, the backlight is switched from the breathing mode to the second normally-on mode, and when the brake is released, the backlight is switched from the second normally-on mode to the breathing mode. When the vehicle has finished starting, namely the vehicle enters a non-flameout state, the backlight lamp is switched to the first normally-on mode from the breathing mode. The reason is that after the vehicle is started, the vehicle is in a running state most of the time, and in this case, the backlight is switched from a dim-and-bright state (breathing mode) to a low-brightness and normally-bright state (first normally-bright mode), so that electric energy can be saved, and the influence of the backlight on the sight or attention of a user can be avoided. That is, when the vehicle is in a non-key-off state, the backlight at the activation switch is in the first normally-on mode most of the time except for a special change in the vehicle state.
The above setting is mainly directed to a scenario in which the vehicle is ignited. When the vehicle finishes starting and enters a non-flameout state, the backlight lamp is in a first normally-on mode. It is considered that the backlight may be triggered to switch from the first normally-on mode to the breathing mode when the vehicle is not turned off, such as when a user presses a brake (discussed in detail later). In the embodiment of the application, when the vehicle is in a non-flameout state, after the backlight lamp completes the breathing cycle for the preset times, the backlight lamp is switched to the first normally-on mode from the breathing mode, so that the first normally-on mode is ensured to be a conventional lighting mode of the non-flameout state of the vehicle, the influence of light of the backlight lamp on the driving of a driver is avoided, and meanwhile, the electric energy can be saved.
Optionally, in this embodiment of the application, when the current vehicle state and the current lighting mode of the backlight satisfy a preset condition, selecting a target lighting mode from lighting modes corresponding to the current contextual model based on the vehicle state and the current lighting mode, and switching the backlight from the current lighting mode to the target lighting mode includes:
when the current lighting mode of the backlight is the first normal lighting mode and the vehicle state satisfies one of the following conditions: when the power mode of the starting switch is switched, or when the vehicle is in a non-flameout state, the brake is pressed down, or when the vehicle is in a non-flameout state, the door of the vehicle is changed from a closed state to an open state, a breathing mode is selected as a target lighting mode from lighting modes corresponding to the current contextual model, and the backlight lamp is switched from a first normal lighting mode to a breathing mode.
The above setting is explained below with reference to a specific application scenario:
scene five
Referring to the above scenario four, the user successfully starts the vehicle, and after the vehicle enters a non-flameout state, the backlight is switched from the breathing mode to the first normally-on mode. After a user drives a vehicle for a period of time, the vehicle is flamed out and is stopped to a certain place, and the user waits for a rest in the vehicle. When the lamp is turned off, the user can press the starting switch, so that the power supply mode is switched, and at the moment, the backlight lamp is switched to the breathing mode from the first normally-on mode. The information that the power mode of the starting switch is changed can be intuitively transmitted to the user by switching the backlight lamp from the low-brightness normal-bright state to the flickering breathing state.
Scene six
Referring to the above scenario four, the user successfully starts the vehicle, and after the vehicle enters a non-flameout state, the backlight is switched from the breathing mode to the first normally-on mode. When a user drives a vehicle to run on a road, the vehicle can be braked when encountering conditions such as pedestrians or roadblocks, and at the moment, when the situation that the brake is stepped on is detected, the backlight lamp is switched from the first normal lighting mode to the breathing mode. The information that the brake is effectively pressed down can be intuitively transmitted to the user by switching the backlight lamp from the low-brightness normally-on state to the flickering breathing state.
Scene seven
Referring to the above scenario four, the user successfully starts the vehicle, and after the vehicle enters the non-flameout state, the backlight is switched to the first normally-on mode from the breathing state. When a user drives a vehicle on a road, the user approaches a convenience store and needs to get off temporarily to buy some articles, in the situation, the user can temporarily stop the vehicle (but the vehicle cannot be flamed out) by engaging an N gear or a P gear, then opens a vehicle door to buy the articles, and at the moment, the backlight lamp is switched from a first normally-on mode to a breathing mode.
Optionally, in this embodiment of the application, when the current vehicle state and the current lighting mode of the backlight satisfy a preset condition, selecting a target lighting mode from lighting modes corresponding to the current contextual model based on the vehicle state and the current lighting mode, and switching the backlight from the current lighting mode to the target lighting mode includes:
when the current lighting mode of the backlight is a breathing mode, and the vehicle state satisfies one of the following conditions: when the vehicle-mounted network of the vehicle enters a dormant state or when the vehicle is locked from the outside, the extinguishing mode is selected as a target lighting mode from the lighting modes corresponding to the current scene mode, and the backlight lamp is switched from the first normally-on mode to the extinguishing mode.
The vehicle is locked from the outside, which means that the driver leaves the vehicle and locks the vehicle by keyless or remote control, inductive locking, or other remote control.
The above setting is explained below with reference to a specific application scenario:
situation eight
Referring to the above scenario four, the user successfully starts the vehicle, and after the vehicle enters the non-flameout state, the backlight is switched to the first normally-on mode from the breathing state. When a user drives the vehicle to go home from work and arrives at a community, the vehicle is flamed out, namely the power supply mode of the starting switch is switched, and at the moment, the backlight lamp is switched from the first normally-on mode to the breathing mode. Meanwhile, the user does not want to get off immediately but continues to wait for a period of time in the vehicle, so that the vehicle-mounted network enters a dormant state after a period of time because the vehicle is not started, and at the moment, the backlight is switched from a breathing mode to a blanking mode, so that the backlight is turned off under the condition that the user does not use the vehicle, and unnecessary power consumption is avoided.
Situation nine
Referring to the above scenario eight, when the user turns off the vehicle, the backlight is switched from the first normally-on mode to the breathing mode. The user opens the door to get off and leave, and locks the vehicle through keyless locking, namely, the vehicle can be locked without taking out the key from the bag, or the vehicle is locked through remote locking, induction locking or other remote control modes, so that the backlight lamp is turned off under the condition that the user does not use the vehicle, and unnecessary power consumption is avoided.
For the color of the light from the backlight, various colors such as white, ice blue, and the like which do not affect the sight of the driver can be set. In the using process, the user can select or switch according to own preference, so that the driving experience is improved.
For the breathing pattern of the backlight, a plurality of breathing cycles may be set. For each breathing cycle, the brightness of the backlight may be set to gradually change from darkest to brightest, and then gradually change from brightest to darkest. For example, a plurality of time points T1ms-T2ms-T3ms-T4ms-T5ms (wherein T5> T4> T3> T2> T1) are set from T1ms to T2ms to T3ms corresponding to a PWM output from small to large, and from T3ms to T4ms to T5ms corresponding to a PWM output from large to small, i.e., at T3ms, corresponding to a maximum PWM output, such as 100%, to complete a breathing cycle. Of course, other breathing cycle methods may also be employed, and the application is not limited thereto.
In the case where the scene mode includes the black day mode and the daytime mode, the above method of switching the lighting mode of the backlight is applicable to both the black day mode and the daytime mode.
The above application scenarios are merely exemplary and are not exhaustive, and the switching setting of the lighting mode of the backlight provided by the embodiments of the present application is not limited to the above application scenarios.
