Description

Technical Field

[0001] The present invention relates to the field of automobile function settings, and in particular to a vehicle light control method, device and vehicle. Background Art

[0002] For car users, they have generally experienced the situation where the whole car is powered off and the driver forgot to turn off a certain headlight after leaving. However, if the car has not been started for a long time, the headlights that have been turned on will continue to consume the battery power, resulting in the risk of battery power failure. In this way, when the owner returns to the car after a long time and wants to start the vehicle, it is very easy for the battery to fail to provide power for the whole vehicle to start, resulting in the need for an external power supply and manual rescue. Summary of the invention

[0003] In view of the defects in the prior art, the technical problem solved by the present invention is: how to automatically turn off the car lights that are still working (turned on) after the car is powered off.

[0004] To achieve the above objectives, in the first aspect, an embodiment of the present application provides a method for controlling vehicle lights, which includes the following steps: after the vehicle is powered off and before the body controller goes into sleep mode, determining whether there are any turned-on vehicle lights; if not, the body controller enters sleep mode normally; if so, in the event that the vehicle lights are not turned on normally, the body controller turns off the vehicle lights and enters sleep mode.

[0005] In combination with the first aspect, in one implementation, the determination condition of abnormal on-state of the vehicle lights includes: no vehicle key is detected within a specified range.

[0006] In combination with the first aspect, in one embodiment, the process for determining that the vehicle key is not detected within the specified range includes: determining whether the signal strength value of the vehicle key is lower than the specified key signal threshold; if so, determining that the vehicle key is not detected within the specified range; otherwise, determining that the vehicle key is detected within the specified range.

[0007] In combination with the first aspect, in one implementation, under the condition that the vehicle key is not detected within the specified range, the determination condition for abnormal start of the vehicle light also includes: an external light intensity value is lower than a specified light intensity threshold.

[0008] In combination with the first aspect, in one implementation, the determination condition of abnormal on-state of the vehicle lights further includes: a vehicle key is detected within a specified range, and the battery voltage is lower than a warning voltage threshold.

[0009] In combination with the first aspect, in one embodiment, the process of determining that the battery voltage is lower than the warning voltage threshold includes: determining whether the battery voltage is continuously lower than the warning voltage threshold within a specified battery voltage monitoring period; if so, determining that the battery voltage is lower than the warning voltage threshold; otherwise, determining that the battery voltage is above the warning voltage threshold.

[0010] In combination with the first aspect, in one implementation, the method further includes the following steps: when the vehicle is powered off, regularly detecting and turning off the working vehicle lights according to a wake-up detection cycle.

[0011] In combination with the first aspect, in one embodiment, the wake-up detection cycle is obtained based on the time required for the headlights to be constantly on until the battery is depleted; the process of regularly detecting and turning off the working headlights according to the wake-up detection cycle when the vehicle is powered off includes: the wake-up detection cycle starts timing after the vehicle is powered off, and if the vehicle is detected to be powered on during the timing process, the timing starts again after the vehicle is powered off.

[0012] In the second aspect, an embodiment of the present application provides a vehicle light control device, which includes a vehicle body controller, and the vehicle body controller is used to: implement the method provided in the first aspect, that is, execute the above method to determine whether there are turned on vehicle lights, if not, enter the sleep state normally, and if so, when the vehicle lights are not turned on normally, the vehicle lights are intelligently turned off and enter the sleep state.

[0013] The input and output signals of each headlight are connected to the corresponding pins of the body controller through hard wires, or communicate with it through the CAN network. After receiving the switch signals of each headlight, the body controller accurately controls each headlight module according to its functional logic requirements.

[0014] The body controller is specifically used for:

[0015] (1) After receiving the external light intensity value signal from the light and rain sensor installed on the front windshield, it is determined whether the external light intensity value is lower than the light intensity threshold; the light and rain sensor and the body controller exchange information through the CAN network.

[0016] (2) Determine whether the signal strength value of the vehicle key received from the indoor antenna is lower than the specified key signal threshold. The basic principle of receiving the signal of the vehicle key is that the body controller starts the key search function and communicates with the successfully matched vehicle key through the wireless signal of the antenna. The vehicle key sends out the key signal strength value, and then the body controller identifies and feeds back the remote control key signal strength value. The larger the strength value, the closer the remote control key is to the indoor antenna, that is, the key is in the car. The smaller the strength value, the farther the remote control key is from the indoor antenna, that is, the key is not in the car.

[0017] (3) Collect the battery voltage and determine whether the battery voltage is lower than the warning voltage threshold.

[0018] (4) After receiving the message from T-BOX to wake itself up, it detects and turns off the lights that are still working; specifically: the Internet of Vehicles platform regularly wakes up T-BOX through remote wireless signals according to the set wake-up detection cycle. After T-BOX is automatically awakened, it forwards messages through the CAN network to wake up the body controller.

[0019] In a third aspect, an embodiment of the present application provides a car, which includes the headlight control device provided in the second aspect.

[0020] Compared with the prior art, the advantages of the present invention are:

[0021] (1) After the vehicle is powered off, the present invention can automatically detect whether there are any lights that are still working (turned on) and automatically turn off the lights that are not turned on normally, thereby avoiding the situation where the lights are always on due to human or other factors forgetting to turn off the lights. This also avoids the battery power being exhausted due to abnormal turning on of electrical equipment when the vehicle is not started. This ensures that the normal power of the battery is not consumed, and provides a better user experience.

[0022] (2) The present invention can achieve refined identification of whether the car lights that are still working are abnormally turned on through specific judgment methods (vehicle key judgment, external light judgment), thereby significantly improving the control accuracy of the car lights.

[0023] (3) When the vehicle is powered off, the system can periodically check and shut down the lights that are still working, thereby improving the control accuracy of the lights and preventing the battery from running low, thereby ensuring that users can use the vehicle normally.

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0029] The flowcharts shown in the accompanying drawings are only examples and do not necessarily include all the contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps may also be decomposed, combined or partially merged, so the actual execution order may change according to actual conditions.

[0030] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0031] In a first aspect, an embodiment of the present application provides a method for controlling vehicle lights, the steps of which include: after the entire vehicle is powered off and before the body control module (Body Control Module, BCM) goes into sleep mode, determining whether there are any vehicle lights that are turned on (the conditions for turning on are: the corresponding vehicle light switch is turned on and there is an enable signal); if not (does not exist), the body controller enters a sleep state normally; if yes (exists), in the case that the vehicle lights are not turned on normally, the body controller intelligently turns off the vehicle lights and then enters a sleep state.

[0032] It can be seen that the present invention can automatically detect whether there are any headlights that are still working (turned on) after the vehicle is powered off, and automatically turn off the headlights that are not turned on normally, thereby avoiding the situation where the headlights are always on due to forgetting to turn off the headlights due to human or other factors. This also avoids the battery power being exhausted due to abnormal turning on of electrical equipment when the vehicle is not started; thereby ensuring that the normal power of the battery is not consumed, and providing a better user experience.

[0033] The specific identification method of abnormally turning on the vehicle lights is described below through several embodiments.

[0034] In one embodiment, the determination conditions for abnormal opening of the vehicle lights include: no vehicle key is detected within a specified range (inside the vehicle), which generally corresponds to a single vehicle key scenario; at the same time, from the above-mentioned need to detect the vehicle key, it can be concluded that the vehicle key in this embodiment needs to have at least a signal transmission function, such as a remote control key or a smart key, and a simple mechanical lock plate key is not within the protection scope of this embodiment.

[0035] The specific determination scheme of the above conditions is: determine whether the signal strength value of the vehicle key is lower than the specified key signal threshold (300, which can be set according to different needs). If so, determine that the vehicle key is not detected within the specified range; otherwise, determine that the vehicle key is detected within the specified range.

[0036] The principle of this design is: by confirming whether the vehicle key is in the car, it is possible to indirectly confirm whether the driver is in the car, so as to distinguish whether the light is turned on manually or forgotten. Therefore, if the vehicle key is detected within the specified range, it means that the key is in the car, that is, the driver is still in the car, so the headlights continue to remain in the original state of lighting; if the vehicle key is not detected within the specified range (at this time, there is generally a behavior of locking the car remotely by closing the door with the vehicle key), it means that the key is not in the car, that is, the driver has left the car, and the headlights that are still working may continue to light up because they were forgotten to be turned off.

[0037] Therefore, the above solution can realize that the vehicle lights that are still working are automatically turned off only when the vehicle key is not in the vehicle, thereby reducing the probability of erroneous operation (ie, the vehicle lights do not actually need to be turned off).

[0038] Furthermore, for external lights, under the condition that the vehicle key is not detected within the specified range, the judgment conditions for abnormal opening of the lights also include: the external light intensity value is lower than the specified light intensity threshold (1200lux, which can be set according to different needs).

[0039] The specific determination scheme of the above conditions is: within the specified light intensity detection time (this time must be less than the time required for the car controller to sleep after power is turned off), collect a number of external light intensity values, and determine whether the average value of the collected external light intensity values ​​is lower than the light intensity threshold (there will be a certain range of errors). If so, determine that the external light intensity value is lower than the light intensity threshold, otherwise determine that the external light intensity value is above the light intensity threshold.

[0040] The design principle is:

[0041] When the driver has left the vehicle (the vehicle key is not detected), the external light intensity value is used to determine whether the current environment is daytime or nighttime, so as to comprehensively judge whether there is an actual need to turn on the lights. This is because some users require the external lights to be turned on at night to identify the night environment, that is, the scene corresponding to the night light recognition environment. For example, for vehicles with the "Go Home with You" function, even if the light switch is not turned on, the headlights will automatically turn on for auxiliary lighting to help the driver illuminate the way home.

[0042] In one embodiment, the determination condition of abnormal light on also includes: the vehicle key is detected within the specified range, and the battery voltage is lower than the warning voltage threshold; this situation generally corresponds to the scenario of multiple vehicle keys. The warning voltage threshold for a single-battery vehicle (such as a sedan or a small commercial vehicle) is generally set to 11.5V, and the warning voltage threshold for a dual-battery vehicle (such as a large commercial vehicle) is generally set to 23.5V, which can actually be set according to different needs.

[0043] The specific determination scheme of the above conditions is: continuously collect the battery voltage through the body controller to determine whether the battery voltage is continuously lower than the warning voltage threshold within the specified battery voltage monitoring time (this time must be less than the time required for the car controller to sleep after power off). If so, it is determined that the battery voltage is lower than the warning voltage threshold; otherwise, it is determined that the battery voltage is above the warning voltage threshold.

[0044] The principle of this design is: in the scenario where there are multiple vehicle keys and one of the keys is forgotten or fixed in the car, if the driver is only indirectly judged by whether the vehicle key is in the car, whether he has left the vehicle may be misjudged. At this time, whether to turn off the lights is determined by detecting whether the battery voltage is lower than the warning voltage threshold. Only when the battery voltage tends to be exhausted to a low voltage, the power supply can be automatically cut off and the lights are prohibited from being lit, thereby ensuring the battery power. It also ensures that the driver can start the engine smoothly when getting in the car, avoiding the situation where the vehicle cannot be started due to forgetting to turn off the external lights.

[0045] It can be seen that the present invention can achieve refined identification of whether the car lights that are still working are abnormally turned on through the above-mentioned specific judgment methods (vehicle key judgment, external light judgment), thereby significantly improving the car light control accuracy.

[0046] In one embodiment, the above method further includes the following steps: when the whole vehicle is powered off, regularly detecting and turning off the vehicle lights that are still working according to the wake-up detection cycle.

[0047] The wake-up detection cycle is obtained based on the time required for many high-power car lights to stay on until the battery tends to be depleted, which is generally 2 hours. The specific execution process of the above method includes: the wake-up detection cycle starts timing after the vehicle is powered off. If the vehicle is powered on during the timing process, the timing will start again after the vehicle is powered off.

[0048] The principle of this design is: in the above scenario, there are still some situations that cause the lights to stay on. Specifically:

[0049] For the above scenario of nighttime headlight recognition environment, before the body controller goes to sleep, the headlights will remain on because the external light intensity is lower than the light intensity threshold (the lights will not be turned off at this time);

[0050] For the above scenario of multiple vehicle keys, before the body controller goes into sleep mode, the lights may remain on because there are keys in the vehicle but the battery is above the warning voltage threshold.

[0051] For all the above scenarios, there may be a situation where the car lights remain on due to signal errors (for example, the vehicle key is not in the car, but the vehicle key is detected in the car due to signal errors, etc.).

[0052] To this end, when the vehicle is powered off, by regularly checking and turning off the lights that are still working, it is possible to improve the accuracy of light control while avoiding battery depletion, thereby ensuring that users can use the car normally.

[0053] The above method is described below through a specific embodiment.

[0054] See also Figure 1 As shown, the process of this embodiment includes:

[0055] S1: Determine whether there are any turned-on lights. If not, go to S5; if so, go to S2.

[0056] S2: Determine whether the signal strength value of the vehicle key is lower than 300. If so, determine that the vehicle key is not detected within the specified range, turn off the interior lights and go to S3, where the lights can be turned off immediately. If the vehicle has a delayed light off function, the lights can also be turned off with a corresponding delay. Otherwise, determine that the vehicle key is detected within the specified range and go to S4.

[0057] S3: Determine whether to turn off the lit external lights according to the external light intensity value and perform corresponding actions; the specific method is: collect the external light intensity value, determine whether the external light intensity value is lower than 1200lux, if so, do not do anything, even if there are lit external lights, do not turn them off, and go to S4; otherwise, turn off the external lights and go to S5.

[0058] S4: After determining whether to turn off all the lit lights according to the battery voltage and executing the corresponding behavior, go to S5; the specific method is: collect the battery voltage, and determine whether the battery voltage is lower than 23.5V (this embodiment is a large commercial vehicle). If so, turn off all the lights and go to S5, otherwise do not do anything, even if there are lit lights, do not turn them off, and go directly to S5.

[0059] S5: When the vehicle is powered off, regularly check and turn off the lights that are still working every 2 hours.

[0060] The execution subject of S1 to S5 is mainly the body controller (which mainly executes the action of turning off the lights). S1 to S4 are completed after the vehicle is powered off and before the body controller goes into sleep.

[0061] In the second aspect, an embodiment of the present application also provides a vehicle light control device, which mainly includes a vehicle body controller, which is used to: execute the above method to determine whether there are turned on vehicle lights, if not, enter the sleep state normally, and if so, in the case that the vehicle lights are not turned on normally, the vehicle lights are intelligently turned off and enter the sleep state.

[0062] See also Figure 2 As shown, the input and output signals of each headlight are connected to the corresponding pins of the body controller through hard wires, or communicate with it through the CAN network. After receiving the switch signals of each headlight, the body controller accurately controls each headlight module according to its functional logic requirements.

[0063] See also Figure 2 As shown, the body controller is specifically used for:

[0064] (1) After receiving the external light intensity value signal from the light and rain sensor installed on the front windshield, it is determined whether the external light intensity value is lower than the light intensity threshold; the light and rain sensor and the body controller exchange information through the CAN network.

[0065] (2) Determine whether the signal strength value of the vehicle key received from the indoor antenna is lower than the specified key signal threshold. The basic principle of receiving the signal of the vehicle key is that the body controller starts the key search function and communicates with the successfully matched vehicle key through the wireless signal of the antenna. The vehicle key sends out the key signal strength value, and then the body controller identifies and feeds back the remote control key signal strength value. The larger the strength value, the closer the remote control key is to the indoor antenna, that is, the key is in the car. The smaller the strength value, the farther the remote control key is from the indoor antenna, that is, the key is not in the car.

[0066] (3) Collect the battery voltage and determine whether the battery voltage is lower than the warning voltage threshold.

[0067] (4) After receiving the message from T-BOX (Telematic BOX, the intelligent vehicle terminal in the Internet of Vehicles system) to wake itself up, it detects and turns off the lights that are still working; specifically: the Internet of Vehicles platform regularly wakes up the T-BOX once according to the set wake-up detection cycle through remote wireless signals. After the T-BOX is automatically awakened, it forwards the message through the CAN network to wake up the body controller.
