Referring to fig. 1, a block diagram of an automobile 100 according to an embodiment of the invention is shown. The automobile 100 includes a rain sensor 110, a sunlight sensor 120, a combination switch 130, a left turn light 140, a right turn light 150, a Body Control Module (BCM) 160, an Airbag controller (airbagcontrol Unit, ACU)11, and a collision sensor 12, wherein the sunlight sensor 120 is electrically connected to the rain sensor 110, the Airbag controller 11 is electrically connected to the collision sensor 12, and the rain sensor 110, the combination switch 130, the left turn light 140, the right turn light 150, and the Airbag controller 11 are electrically connected to the Body Control Module 160.
The sunlight sensor 120 is configured to collect light intensity information and output a corresponding light intensity level to the rainfall sensor 110 according to the light intensity information.
In this embodiment, a plurality of light intensity levels (for example, weak, medium, strong, and extra strong) are calibrated in advance in the solar sensor 120, each light intensity level corresponds to one light intensity range, and the solar sensor 120 determines the corresponding light intensity level according to the light intensity range in which the currently acquired light intensity information is located, and then outputs the light intensity level to the rainfall sensor 110. It should be noted that the light intensity levels calibrated in the solar sensor 120 are not limited to the above five types, and may be increased or decreased during calibration in practical applications; the solar sensor 120 collects light intensity information in real time without a special switch to control the on and off of the light intensity information.
The rainfall sensor 110 is configured to, when the combination switch 130 is in the automatic operating mode, acquire rainfall information and determine a rainfall level corresponding to the rainfall information, determine a visibility level of a current environment according to the rainfall level and the light intensity level, and send a first double flashing light turning-on instruction to the vehicle body control module 160 when the visibility level does not exceed a preset level.
In this embodiment, the combination switch 130 is an integration of a turn light switch and a wiper switch, and when the automobile 100 runs in a rainy day, a driver needs to turn on the wiper switch through the combination switch 130 and adjust the wiper switch to an Automatic (AUTO) operating mode, so as to turn on the rainfall sensor 110, and the rainfall sensor 110 collects rainfall information. The rainfall sensor 110 is also pre-calibrated with a plurality of rainfall levels (e.g., downy rain, light rain, medium rain, heavy rain), each rainfall level corresponds to a rainfall range, and the rainfall sensor 110 determines the corresponding rainfall level according to the rainfall range in which the collected rainfall information is located.
In this embodiment, the rainfall sensor 110 is pre-stored with a visibility rating table, the visibility rating table includes a corresponding relationship between a rainfall level, a light intensity level and a visibility level, and the rainfall sensor 110 is configured to determine a corresponding visibility level in the visibility rating table according to the rainfall level and the light intensity level. As shown in the visibility ranking table in fig. 2, 6 visibility rankings are divided into "0", "1", "2", "3", "4", and "5", respectively. Wherein, the visibility grade is '0' to indicate that the visibility is good, and the corresponding visibility range is x is more than or equal to 10.0 km; the visibility grade is '1' which means that the visibility is better, and the corresponding visibility range is 1.5 km-x < 10 km; the visibility grade is '2' which indicates that the visibility is poor, and the corresponding visibility range is x which is more than or equal to 0.5km and less than 1.5 km; the visibility grade is 3, which indicates poor visibility, and the corresponding visibility range is x which is more than or equal to 0.2km and less than 0.5 km; the visibility grade is '4', which means that the visibility is poor, and the corresponding visibility range is more than or equal to 0.05km and less than or equal to x and less than 0.2 km; a visibility rating of "5" indicates very poor visibility, corresponding to a visibility range of x < 0.05 km. The rainfall sensor 110 periodically (for example, with a period of 100 ms) determines a corresponding visibility level according to the currently obtained rainfall level and the light intensity level, compares the visibility level with a preset level, and sends a first double-flashing-light turning-on instruction to the vehicle body control module 160 if the visibility level does not exceed the preset level. For example, assuming that the preset level is "4", the rainfall sensor 110 sends a first strobe turning-on instruction to the vehicle body control module 160 when the visibility level is "4" or "5".
The airbag controller 11 is configured to determine whether the automobile 100 is collided according to the detection signal sent by the collision sensor 12, and send a second flashing light turning-on instruction to the body control module 160 when it is determined that the automobile 100 is collided.
In the present embodiment, the number of the collision sensors 12 for detecting whether the automobile 100 collides may be 4, and the collision sensors are respectively disposed at different positions on the automobile 100, for example, a front collision sensor, a rear collision sensor, and side collision sensors respectively mounted on left and right door center pillars. When the automobile 100 collides, the collision sensor 12 vibrates or displaces, so as to send a corresponding detection signal to the airbag controller 11; the airbag controller 11 sends a second flashing light turning-on command to the body control module 160 after determining that the vehicle 100 has collided according to the received detection signal.
The vehicle body control module 160 is configured to execute the second dual-flash-lamp turning-on instruction to control the left turn lamp 140 and the right turn lamp 150 to be turned on simultaneously when the vehicle speed of the vehicle 100 is less than or equal to a preset value, execute the turn-lamp turning-on instruction to control the left turn lamp 140 or the right turn lamp 150 to be turned on when the vehicle speed of the vehicle 100 is greater than the preset value and the turn-lamp turning-on instruction is received, and execute the first dual-flash-lamp turning-on instruction to control the left turn lamp 140 and the right turn lamp 150 to be turned on simultaneously when the vehicle speed of the vehicle 100 is greater than the preset value and the turn-lamp turning-on instruction is not received.
In this embodiment, the priority level of the control system for automatically opening the double flashing in case of collision is higher than the priority level of the control system for turning the indicator, and the priority level of the control system for automatically opening the double flashing in rainy days is higher than the priority level of the control system for automatically opening the double flashing in rainy days, so that the control system for automatically opening the double flashing in rainy days can not affect the basic requirements of emergencies when working, namely, when the automobile 100 collides, the control system automatically opens the double flashing, and the basic requirements of normal driving of the automobile 100 can not be affected, namely, the use of the steering function is realized. For example, when the automobile 100 runs in an environment with low visibility in rainy days and a collision occurs, the automobile body control module 160 may receive a first double-flashing-light turning-on instruction and a second double-flashing-light turning-on instruction, and the automobile body control module 160 needs to judge whether the speed of the automobile 100 is less than or equal to 10km/h, and if so, determines that the automobile 100 is currently in a low-speed or stopped state, needs to turn on double flashing, and simultaneously turns off the double-flashing function and the steering function in rainy days, that is, does not execute the first double-flashing-light turning-on instruction and the steering-light turning-on instruction; when the speed of the automobile 100 is greater than 10km/h (i.e., the automobile 100 is not in a low speed or stop state after collision), the second double-flashing-light turning-on instruction does not need to be executed, the function of the automobile 100 that turns to is prioritized is turned on, if the automobile body control module 160 receives the turning-light turning-on instruction at this time, the turning-light turning-on instruction is preferentially executed to turn on the left turning light 140 or the right turning light 150, and if the automobile body control module 160 does not receive the turning-light turning-on instruction at this time, the first double-flashing-light turning-on instruction is executed, so that the function of automatically turning on double flashing when the automobile 100 runs in an environment with low visibility in rainy days is realized.
The vehicle body control module 160 is further configured to execute the turn signal turning-on instruction to control the left turn signal 140 or the right turn signal 150 to be turned on when the first dual flash light turning-on instruction and the second dual flash light turning-on instruction are not received and the turn signal turning-on instruction is received; when the second dual flashing light turning-on command is not received, the turn signal turning-on command is not received, and the first dual flashing light turning-on command is received, the first dual flashing light turning-on command is executed to control the left turn signal 140 and the right turn signal 150 to be turned on simultaneously.
That is, when the automobile 100 is neither collided nor driven in an environment with a low visibility level, the body control module 160 does not receive the first dual flash light turning-on instruction and the second dual flash light turning-on instruction, and if the turn light turning-on instruction is received at this time, the turn light turning-on instruction is executed; when the automobile 100 runs in an environment with low visibility level and no collision occurs, the automobile body control module 160 receives a first double-flashing-light starting instruction, does not receive a second double-flashing-light starting instruction, and executes the first double-flashing-light starting instruction if the turning-light starting instruction is not received; if the turn signal lamp starting instruction is received, the turn signal lamp starting instruction is preferentially executed, and the first double-flash-lamp starting instruction is suspended.
The body control module 160 is further configured to control the left turn light 140 or the right turn light 150 to be turned off when receiving a turn light turn-off command in the process of executing the turn light turn-on command.
For example, when the body control module 160 receives a turn signal turning-on command during execution of a first dual flashing light turning-on command, the turn signal turning-on command is preferentially executed, and execution of the first dual flashing light turning-on command is suspended; when a turn-off command of the turn lights is received, the left turn light 140 or the right turn light 150 is controlled to be turned off, and then the first double flashing light turn-on command is continuously executed.
In the present embodiment, the turn signal on command or the turn signal off command may be obtained by the driver manually operating the turn signal switch in the combination switch 130, or may be automatically generated by the automobile 100 according to the driving state. Next, a principle of automatically generating a turn-on command or a turn-off command of the turn lights will be explained.
The automobile 100 further includes a camera 101, a lane auxiliary control module 102, an Electronic Stability Controller (ESC) 103 and a corner sensor 104, wherein the camera 101 and the ESC 103 are electrically connected to the lane auxiliary control module 102, and the ESC 103 is electrically connected to the corner sensor 104.
The camera 101 is configured to collect lane information of the vehicle 100, and send the lane information to the lane assist control module 102.
In the present embodiment, the camera 101 may detect red, yellow and green traffic lights in front of the automobile 100, lane positions (white lines on roads, arrow lines of turns, etc.), so as to obtain information about the lane where the automobile 100 is currently located.
The electronic stability control device 103 is configured to acquire angle information of a steering wheel of the automobile 100 through the steering angle sensor 104, and send the angle information to the lane assist control module 102.
In the embodiment, the rotation angle sensor 104 is used for detecting the speed and the amplitude of the rotation of the steering wheel, so as to obtain corresponding angle information, and the angle information is sent to the lane assist control module 102 through the electronic stability control device 103.
The lane auxiliary control module 102 is configured to send the turn signal turning-on instruction or the turn signal turning-off instruction to the vehicle body control module 160 according to the lane information and the angle information.
In this embodiment, after receiving the lane information and the angle information, the lane assist control module 102 determines whether the intention of the driver is steering, returning to the right, or deviating according to the lane information and the angle information, and then determines to send a turn-on command or a turn-off command of the turn lights. For example, when it is determined that the vehicle is turning (left-turning or right-turning), a turn signal turn-on command (a command to turn on the left turn signal 140 or a command to turn on the right turn signal 150) is transmitted to the vehicle body control module 160, so that the vehicle body control module 160 controls the left turn signal 140 to be turned on or the right turn signal 150 to be turned on; when it is determined that the lane has been returned, a turn lamp turn-off command is transmitted to the body control module 160, so that the body control module 160 controls the left turn lamp 140 to be turned off or the right turn lamp 150 to be turned off. In this embodiment, when the vehicle 100 is driving, if the driver does not turn on the turn signal, when the vehicle 100 deviates from the current lane, and the system determines that the vehicle 100 deviates from the lane without steering requirement, the lane assist control module 102 may prompt the driver, and after more than 5 seconds, if the driver does not turn on the turn signal, the system automatically turns on the turn signal to prompt the vehicle behind to deviate from the lane, and when the vehicle 100 returns, the control system automatically generates the turn signal turn-on command or the turn signal turn-off command to turn off.
In this embodiment, the automobile 100 further includes a lane departure warning light 105, the lane departure warning light 105 is electrically connected to the lane auxiliary control module 102, the lane departure warning light 105 may be disposed on a rear view mirror of the automobile 100, and when the automobile 100 departs from a lane, the lane auxiliary control module 102 controls the lane departure warning light 105 to light or flash so as to remind a driver of the departure of the automobile from the lane.
In this embodiment, the body control module 160 is configured to determine whether the automobile 100 is in a forward state when receiving the turn signal turning-on instruction, and control the left turn signal 140 or the right turn signal 150 to turn on according to the turn signal turning-on instruction when the automobile 100 is in the forward state. That is, the vehicle 100 does not need to turn on the turn signal when the vehicle is reversing, and therefore, after receiving the turn signal turn-on command, the vehicle body control module 160 needs to further determine whether the vehicle 100 is in the reversing state, and the vehicle body control module 160 will execute the turn signal turn-on command only when the vehicle 100 is not in the reversing state.
It should be noted that, in the present embodiment, the vehicle body control module 160 executes the automatically generated turn-on command only after executing the automatically generated turn-on command, and the vehicle body control module 160 does not automatically turn off by the driver operating the turn light turned on by the turn light switch.
In this embodiment, the rainfall sensor 110 is further configured to send a double flashing light turning-off instruction to the vehicle body control module 160 when the visibility level is increased to exceed the preset level. For example, when the visibility level of the current environment is increased from "4" or "5" to "1", "2", or "3", the rainfall sensor 110 sends a double flashing light off command to the body control module 160.
The vehicle body control module 160 is further configured to control the left turn light 140 and the right turn light 150 to be turned off simultaneously according to the dual flashing light turning-off command when the first dual flashing light turning-on command is executed.
That is, after the automobile 100 starts the double flashing, if the visibility of the current environment is improved to a level that does not satisfy the condition of starting the double flashing, the body control module 160 controls the left turn light 140 and the right turn light 150 to be simultaneously turned off according to the double flashing light turning-off command sent by the rainfall sensor 110, so as to implement the turning-off of the double flashing; of course, if the turn signal turn-on command is received simultaneously with the double flashing light turn-off command, the turn signal turn-on command is preferentially executed, and after the turn signal turn-off operation is completed, the left turn signal 140 and the right turn signal 150 are controlled to be turned off simultaneously according to the double flashing light turn-off command sent by the rainfall sensor 110. In the present embodiment, when the automobile 100 is turned on due to a collision, even if the body control module 160 receives the double flashing light turn-off command sent by the rainfall sensor 110, the double flashing will not be turned off.
Further, the automobile 100 further includes a combination meter 170, the combination meter 170 is electrically connected to the automobile body control module 160, and the automobile body control module 160 is further configured to send a prompt message to the combination meter 170 according to the first double-flashing-light turning-on instruction when receiving the first double-flashing-light turning-on instruction, so as to prompt the driver to reduce the automobile speed.
