The vehicle light type information brightness level judgment unit is used for judging the brightness level of the alarm lamp suitable for the current vehicle light according to the vehicle light type information.
In the brightness adjusting device, four schemes are available in total to judge the brightness level, and some or one of the four schemes is adopted to judge the brightness level according to the configuration of the vehicle, wherein if the four schemes can be applied, the priority of ambient brightness information acquisition is highest when information acquisition is carried out, then vehicle light type information acquisition is carried out, and then information acquisition of combined information of weather and time is carried out, and the priority is time information acquisition when the priority is lowest.
Further, the brightness adjusting device is provided with a fault prompting module, and the fault prompting module can obtain fault information fed back by the brightness control module and send prompting information to prompt a driver that the alarm lamp has a fault. The prompt information can be prompted by flashing of an instrument panel.
Further, the brightness adjusting device is provided with a manual control module, the manual control module is used for manually selecting the brightness level, the manual control module comprises a brightness level selection unit, and the brightness level selection unit is used for manually selecting the brightness level and sending a signal value corresponding to the brightness level to the brightness control module. The priority of the manual control module is greater than that of the brightness control module, namely when the brightness level is selected through the manual control module, the brightness control module adjusts the brightness according to the priority set by the manual control module. The device also comprises a manual adjustment storage module, wherein the manual adjustment storage module is used for memorizing the manually adjusted alarm lamp brightness and the current control information.
Further, the device also comprises a blind area obstacle relative speed detection module, wherein the blind area obstacle relative speed detection module is used for detecting the relative speed of the obstacle and the vehicle.
Furthermore, the device also comprises a risk grade judging module, wherein the risk grade judging module is used for judging the risk grade according to the relative speed, and different risk grades correspond to different reminding modes. When the barrier in the blind area is far away from the vehicle, the risk level is low, and only light reminding can be adopted. When the barrier in the blind area is close to the vehicle, the risk level is high, and at the moment, the forms of voice alarm, light flicker and the like are adopted to remind the driver of paying attention.
Specifically, when the blind area obstacle detection module detects that an obstacle exists in the blind area, the alarm lamp control module starts an alarm lamp to remind a driver of paying attention. After the control information is obtained, the brightness control module adjusts the brightness of the alarm lamp to be proper according to the judgment result of the brightness grade judgment module. At this time, it is possible to determine whether the driver has an intention to change the lane by information obtained by turning on a turn signal or a steering wheel torque sensor or the like. When the alarm lamp was opened, the driver tried to change the way, and the alarm lamp can twinkle this moment and remind to through other means such as sound, remind the driver to notice, there is the risk in the change of way this moment. When the alarm lamp was opened, blind area barrier relative speed detection module also can detect the relative speed of barrier and vehicle to judge the risk level, when judging the risk level higher, remind the driver to notice through sound or light scintillation.
In the brightness adjusting device, when the brightness level is judged according to the environment brightness information, the brightness adjusting device is provided with a brightness sensor, the brightness sensor can obtain the environment brightness information and send the environment brightness information to a brightness level judging module, and the brightness level is judged by an environment brightness information brightness level judging unit. The environment brightness information brightness level judging unit can set different signal values according to environment brightness information with different brightness, the signal values correspond to nine early warning lamp brightness values with different levels and an early warning lamp brightness default value respectively, and the brightness is enhanced from the 1 st level to the 9 th level. As shown in the table below.
For example, when an obstacle is detected to exist in the blind area, a warning lamp is turned on to remind a driver, and meanwhile current ambient brightness information is obtained. When the brightness information obtained by the brightness sensor is between (a-b) lx, the ambient brightness information brightness level judging unit sends a signal value corresponding to (a-b) lx to the brightness control module, and the brightness control module adjusts the brightness of the alarm lamp to 2 levels according to the signal value.
When the brightness sensor can not obtain the brightness information, the ambient brightness information brightness level judging unit outputs a signal value corresponding to an invalid value, and when the brightness control module obtains the invalid value, a default value is executed, and the alarm lamp is adjusted to be the default value brightness.
In the brightness adjustment device, when the brightness level is determined based on the combination information of weather and time, the time and the weather are combined based on different time periods and different weather conditions, for example, in the morning on a sunny day or in the evening on a rainy day, and then the brightness level is determined based on the combination information. The weather information and the time information can be obtained through networking. According to different combination information, the combination information brightness level judgment unit sets different signal values which respectively correspond to nine early warning lamp brightness values with different levels and an early warning lamp brightness default value, and the brightness is enhanced from the 1 st level to the 9 th level.
As shown in the table below.
Wherein X represents sunny days, Y represents cloudy days, Z represents cloudy days or rainy days, and P represents that weather information cannot be acquired. A corresponds to 10 am to 2 pm, B corresponds to 8 am to 10 am and 2 pm to 4 pm, C corresponds to 6 am to 8 am and 4 pm to 6 pm, D corresponds to 6 pm to 6 am, and E corresponds to no time information.
For example, when an obstacle is detected in the blind area, a warning lamp is turned on to remind the driver, and the current combined information is obtained. When the combined information obtained by the combined information obtaining module is A & Y, namely corresponding to 10 am to 2 pm in cloudy weather, the combined information brightness level judging unit sends a signal value corresponding to the A & Y to the brightness control module, and the brightness control module adjusts the brightness of the alarm lamp to be 8 levels according to the signal value.
When the weather information obtaining unit cannot obtain the weather information or the time information obtaining unit cannot obtain the time information, the combined information brightness level judging unit outputs a signal value corresponding to an invalid value, and when the brightness control module obtains the invalid value, a default value is executed, and the alarm lamp is adjusted to be the default value brightness.
In the luminance adjusting apparatus, the luminance level may be determined based on only the time information. The brightness is adjusted according to different time periods in the day and night. The brightness is improved in the daytime, the condition that the alarm lamp is not obvious is avoided, the brightness is reduced at night, and the condition that the alarm lamp is too dazzling is avoided. According to different time information, the time information brightness level judging unit sets different signal values which respectively correspond to 9 early warning lamp brightness values with different levels and an early warning lamp brightness default value, and the brightness is enhanced from the 1 st level to the 9 th level.
As shown in the table below.
Wherein, A corresponds to 10 am to 2 pm, B corresponds to 8 am to 10 am and 2 pm to 4 pm, C corresponds to 6 am to 8 am and 4 pm to 6 pm, D corresponds to 6 pm to 6 am, and E corresponds to no time information.
For example, when an obstacle is detected in the blind area, a warning lamp is turned on to remind the driver, and the current time information is obtained. When the time information obtained by the time information obtaining unit is A, namely corresponding to 10 am to 2 pm, the time information brightness level judging unit sends a signal value corresponding to A to the brightness control module, and the brightness control module adjusts the brightness of the alarm lamp to 7 levels according to the signal value.
When the time information obtaining unit can not obtain the time information, the time information brightness level judging unit outputs a signal value corresponding to an invalid value, and when the brightness control module obtains the invalid value, a default value is executed, and the alarm lamp is adjusted to be the default value brightness.
In the brightness adjusting device, the brightness level can be judged according to the type information of the vehicle light. During driving, the vehicle can also have lights which indicate the driving state of the vehicle, the driving state of the vehicle reflects the external environment condition, such as fog light opening for indicating in a heavy fog environment, and low beam light opening for indicating in a dim environment, and under such a condition, the driver needs a clearer early warning. For example: the front fog lamp and the rear fog lamp represent that the vehicle runs in a foggy environment, so that when a driver arrives at a blind spot, the driver needs to give a more clear early warning and needs to improve the brightness of the warning lamp. According to different vehicle light type information, the vehicle light type information brightness level judging unit sets different signal values which respectively correspond to nine early warning lamp brightness values with different levels and an early warning lamp brightness default value, and the brightness is enhanced from the 1 st level to the 9 th level. As shown in the table below.
Wherein a is the high beam on, b is the dipped headlight on, c is the Auto-stop on, d is the front fog light and the back fog light on, e is the driving light on or the light off, f is the state that the light can not be obtained.
For example, when an obstacle is detected in the blind area, a warning lamp is turned on to remind the driver, and the current time information is obtained. When the vehicle light type information obtained by the vehicle light type information obtaining module is b, namely the corresponding dipped headlight is turned on, the vehicle light type information brightness level judging unit sends a signal value corresponding to b to the brightness control module, and the brightness control module adjusts the brightness of the alarm lamp to be 3 levels according to the signal value.
When the vehicle light type information obtaining module cannot obtain the vehicle light type information, the vehicle light type information brightness level judging unit outputs a signal value corresponding to an invalid value, and when the brightness control module obtains the invalid value, a default value is executed, and the alarm lamp is adjusted to be the default value brightness.
According to the blind spot monitoring alarm lamp brightness adjusting device, brightness grade judgment can be carried out on the device according to environment brightness information, or brightness grade judgment can be carried out on weather and time combined information, or brightness grade judgment can be carried out on time information, or brightness grade judgment can be carried out on vehicle light type information, higher compatibility can be achieved, and one of the four schemes can be selected according to vehicle configuration to carry out corresponding control. When the brightness is adjusted and controlled, a relatively simple control logic is adopted, a controller is added or the existing controller is relied on, the signal sending end for driving the lamp to be lightened is used for distinguishing and sending, and the alarm lamp can realize the brightness control according to the signal execution. In addition, because brightness adjusting device can adjust the luminance of alarm lamp, avoids appearing the not obvious or dazzling phenomenon of suggestion, promotes the driving impression.

Further, after the detection information of the blind area obstacles is obtained, the relative speed of the blind area obstacles and the vehicle is obtained, the risk level is judged, and when the risk level is high, the driver is reminded to pay attention.
Further, when a fault occurs, the fault prompting module can obtain fault information fed back by the brightness control module and send prompting information to prompt a driver that the alarm lamp has a fault. The prompt information can be prompted by flashing of an instrument panel.
Further, when the driver manually adjusts, the driver manually selects the brightness level and sends a signal value corresponding to the brightness level to the brightness control module. The priority of the manual control module is greater than that of the brightness control module, namely, when the brightness level is selected by the manual control module, the brightness control module adjusts the brightness according to the priority set by the manual control module.
Further, the obtaining the corresponding brightness level of the alarm lamp according to the current parameter of the brightness control information includes:
comparing different parameters of the brightness control information with the brightness of the alarm lamp to obtain the corresponding relation between the parameters of the brightness control information and the brightness of the alarm lamp;
and acquiring the corresponding brightness level of the alarm lamp according to the corresponding relation and the current parameter of the brightness control information.
Specifically, when the blind area obstacle detection module detects that an obstacle exists in the blind area, the alarm lamp control module starts an alarm lamp to remind a driver of paying attention. After the control information is obtained, the brightness control module adjusts the brightness of the alarm lamp to be proper according to the judgment result of the brightness grade judgment module. At this time, it is possible to determine whether the driver has an intention to change the lane by information obtained by turning on a turn signal or a steering wheel torque sensor or the like. When the alarm lamp was opened, the driver tried to change the way, and the alarm lamp can twinkle this moment and remind to through other means such as sound, remind the driver to notice, there is the risk in the change of way this moment. When the alarm lamp was opened, blind area barrier relative speed detection module also can detect the relative speed of barrier and vehicle to judge the risk level, when judging the risk level higher, remind the driver to notice through sound or light scintillation.
In the brightness adjusting device, brightness level judgment can be performed according to environment brightness information, brightness level judgment can be performed according to weather and time combination information, brightness level judgment can be performed according to time information, and brightness level judgment can be performed according to vehicle light type information. The four schemes can judge the brightness level, and some or one of the four schemes is adopted to judge the brightness level according to the configuration of the vehicle, wherein if the four schemes can be applied, the priority of the judgment of the brightness level according to the ambient brightness information is the highest, the judgment of the brightness level according to the type information of the vehicle light is carried out, the judgment of the brightness level according to the combined information of the weather and the time is carried out again, and the judgment of the brightness level according to the time information is carried out when the priority is the lowest.
According to the method for adjusting the brightness of the blind spot monitoring alarm lamp, the brightness level can be judged according to the environment brightness information, or the brightness level can be judged according to the weather and time combination information, or the brightness level can be judged according to the time information, or the brightness level can be judged according to the vehicle light type information, so that the method has higher compatibility, and can select one of the four schemes to perform corresponding control according to the configuration of a vehicle. When the brightness is adjusted and controlled, a relatively simple control logic is adopted, a controller is added or the existing controller is relied on, the signal sending end for driving the lamp to be lightened is used for distinguishing and sending, and the alarm lamp can realize the brightness control according to the signal execution. In addition, because brightness adjusting device can adjust the luminance of alarm lamp, avoids appearing the not obvious or dazzling phenomenon of suggestion, promotes the driving impression.
