Example one
Referring to fig. 3, a cue light control method according to a first embodiment of the present invention is shown, and is applied to a vehicle, and may be applied to a controller of the vehicle, where the left and right sides of the vehicle are respectively provided with a detection radar and an external rearview mirror with a cue light, and the method specifically includes steps S01 to S03.
Step S01, acquiring detection information obtained by the detection radar detecting the moving target on the side where the detection radar is located, wherein the detection information comprises the relative speed and the relative distance between the moving target and the vehicle.
During specific implementation, the main radar on the left side of the vehicle detects moving target information on the left side of the vehicle and sends the detection information to the controller (such as central control) through the whole vehicle CAN, the main radar on the right side of the vehicle detects the moving target information on the left side of the vehicle and sends the detection information to the main radar through radio frequency, and the main radar sends the detection information to the controller (such as central control) through the whole vehicle CAN, so that the controller CAN acquire the detection information of the two detection radars from the whole vehicle CAN.
And step S02, determining a preset prompt level corresponding to the moving target according to the relative speed and the relative distance.
In some optional embodiments, a detection information-prompt level mapping table may be pre-established, and different relative speed and relative distance combinations and corresponding preset prompt levels thereof may be entered into the detection information-prompt level mapping table, so that the preset prompt level corresponding to the moving target may be determined by looking up the mapping table according to the relative speed and relative distance between the moving target and the vehicle. Or, in other alternative embodiments, the meeting time required for the moving target to move to meet the vehicle may be calculated according to the relative speed and the relative distance, and the prompt level corresponding to the meeting time is determined by searching a preset time-prompt level mapping table, where the time-prompt level mapping table records different meeting times and corresponding preset prompt levels, so as to determine the preset prompt level corresponding to the moving target by searching the table according to the time.
And step S03, controlling the prompting lamp at one side of the moving target to light and prompt according to a preset lighting mode corresponding to the preset prompting level.
In specific implementation, a prompting level-lighting mode mapping table can be established in advance, different prompting levels and preset lighting modes corresponding to the prompting levels are recorded into the prompting level-lighting mode mapping table, and therefore the preset lighting modes corresponding to the preset prompting levels can be determined through table lookup of the prompting levels in the follow-up process.
In some preferred embodiments, the preset prompting levels include a first preset prompting level, a second preset prompting level and a third preset prompting level, which are set from high to low, that is, three prompting levels are preset in total, and the lighting modes of the prompting lamps corresponding to the third preset prompting level, the second preset prompting level and the first preset prompting level may be long-lighting, low-frequency flashing and high-frequency high-brightness flashing in sequence, that is, when the third preset prompting level is determined, the lighting mode of the prompting lamps is long-lighting; when the second preset prompt level is determined, the lighting mode of the prompt lamp is low-frequency flickering; when the first preset prompt level is determined, the lighting mode of the prompt lamp is high-frequency highlight flashing, namely the higher the level is, the more obvious the lighting mode of the prompt lamp is, so that a better safety prompt effect is achieved.
In order to better perform table lookup to determine the prompt level and the lighting mode, the time-prompt level mapping table and the prompt level-lighting mode mapping table can also be combined into a mapping table to form a time-prompt level-lighting mode mapping table, so that the finally required lighting mode can be directly determined in one table. Referring to table 1 below, a time-cue level-lighting manner mapping table according to the present embodiment is shown:
table 1:
| lighting system | Prompt level | TTC |
| Long bright | C | ≤3.5s |
| Low frequency flicker | B | ≤3s |
| High frequency highlight flicker | A | ≤2.5s |
The method comprises the steps of obtaining a first preset prompting level, a second preset prompting level and a third preset prompting level, wherein TTC is L/V, represents the meeting time required for a moving target to move to meet the vehicle, L represents the relative distance between the moving target and the vehicle, V represents the relative speed between the moving target and the vehicle, A is the first preset prompting level, B is the second preset prompting level, and C is the third preset prompting level.
It should be noted that the TTC threshold value (e.g. 3.5s) given in table 1 is only to verify the applicability of the present application, and is only a set of feasible embodiments given in the present application, but this does not mean that only this set of TTC threshold value is provided, and in the specific implementation, the adaptive adjustment may be performed according to the driving habits of different vehicle models and different drivers, for example, for a vehicle model with a longer vehicle body, because the time required for lane change is correspondingly increased, the TTC threshold value may be correspondingly increased, so that the coming vehicle prompt may be performed in advance, and a better prompt effect may be achieved.
In summary, in the warning light control method in the above embodiment of the present invention, the relative speed and the relative distance between the moving target and the vehicle are detected by the detection radar, the warning level required to perform the safety warning is determined according to the detected relative speed and the detected relative distance, and the warning light on the side where the moving target is located is turned on according to the preset lighting manner corresponding to the determined warning level, so that the safety warning is performed in different lighting manners, so that the driver can obtain more information of the moving target from the different lighting manners of the warning light, and the safety warning effect is improved.
Example two
Referring to fig. 4, a cue light control method according to a second embodiment of the present invention is shown, applied to a vehicle, where the left and right sides of the vehicle are respectively provided with a detection radar and an exterior mirror with a cue light, and the method specifically includes steps S11 to S16.
Step S11, acquiring detection information obtained by the detection radar detecting the moving target on the side where the detection radar is located, wherein the detection information comprises the relative speed and the relative distance between the moving target and the vehicle.
And step S12, calculating the meeting time required for the moving target to move to meet the vehicle according to the relative speed and the relative distance.
The formula for calculating the meeting time is as follows: TTC represents a vehicle-crossing time required for the moving target to move into meeting with the host vehicle, L represents a relative distance between the moving target and the host vehicle, and V represents a relative speed between the moving target and the host vehicle.
And step S13, determining a preset prompt level corresponding to the moving target according to the meeting time and the relative speed.
In specific implementation, the step S13 may be specifically implemented according to the following refining steps, where the refining steps specifically include:
and acquiring a preset prompt level corresponding to the meeting time and the relative speed from a pre-stored mapping table so as to obtain a preset prompt level corresponding to the moving target.
And step S14, controlling the prompting lamp at one side of the moving target to light and prompt according to a preset lighting mode corresponding to the preset prompting level.
It should be noted that, referring to table 1, in the first embodiment, the lighting method is mapped by using the meeting time only, that is, the meeting time is used as the only determination parameter for the warning light to give the safety warning, and there is a disadvantage that the speed of the vehicle coming from the side direction cannot be fed back to the driver, for example, the current time for the vehicle in the right rear of the vehicle to meet the vehicle is 3.5s, then according to the mapping table given in table 1, the warning light on the right rear view mirror is long-lighted for making the normal warning, so as to give a warning that the vehicle comes from the right rear but has a relatively long time to meet the vehicle, at this time, if the speed of the vehicle in the right rear is fast, and the driver obtains a warning that the vehicle still has a lane change, at this time, the vehicle in the right rear is fast due to the speed, and the response and braking time are short, so that the collision is likely to occur, Traffic accidents such as scratching. Therefore, the embodiment is further optimized, the relative speed is included in the judgment parameters for safety prompt of the prompt lamp, that is, the preset prompt level corresponding to the moving target is determined according to the meeting time and the relative speed, and the preset lighting mode is determined according to the preset prompt level.
Referring to table 2 below, an example of the pre-stored mapping table in the present embodiment is shown:
table 2:
| lighting system | Object type | Relative velocity | TTC | |
| Long bright | C | 0～10m/s | ≤3.5s | |
| Low | B | 10～15m/s | ≤3.5s | |
| High frequency highlight flicker | A | 15～20m/s | ≤3.5s | |
| Low frequency flicker | B | 0～10m/s | ≤3s | |
| High frequency | A | 10～15m/s | ≤3s | |
| High frequency highlight flicker | A | 0～10m/s | ≤2.5s |
Wherein, A is a first preset prompt level, B is a second preset prompt level, and C is a third preset prompt level. It can be understood that the faster the relative speed, the faster the speed of representing the moving target, therefore, the relative speed is incorporated into the judgment parameter of the safety prompt of the prompting lamp, so that the driver can generally master the speed and meeting time of the vehicle coming from the rear through the lighting mode of the lifting lamp, and therefore more correct driving operation can be performed, and safety accidents can be better avoided.
It should be noted that the TTC threshold (e.g. 3.5s) and the relative speed threshold (e.g. 10m/s) given in table 1 above are only for verifying the applicability of the present application, and are only one set of possible embodiments given in the present application, but this does not mean that only this set of TTC threshold and relative speed threshold is available, and in the specific implementation, the adaptive adjustment may be made according to the driving habits of different vehicle models and different drivers.
Step S15, it is detected whether there is an event that satisfies an alarm condition made to the side where the moving object is located.
Wherein the event satisfying the alarm condition comprises a turn signal, a door open and/or a lane change event. When the detection result is yes, that is, there is an event made to the side where the indicator lamp that has been turned on, that satisfies the alarm condition, step S16 is executed.
And step S16, controlling the instrument alarm to send out alarm sound prompt.
By way of example and not limitation, when the meeting time of the moving target and the vehicle is detected by the detection radar (main radar) on the left side meets the prompt condition, the prompt lamp of the left side outer rearview mirror is turned on, and if the driver turns the steering wheel to the left, dials the left steering lamp and/or opens the left vehicle door at the moment, the vehicle-mounted MP5 sends out a warning sound prompt to avoid the collision risk caused by lane change or door opening.
Further, in some optional embodiments of the present invention, the method may further comprise:
and under the same preset prompt level, the meeting time required by the moving target at the assistant driving side is longer than that required by the moving target at the main driving side.
It should be noted that, since the passenger side is farther from the driver, the blind area on the passenger side is larger than that on the driver side, and in order to further improve the safety prompting effect, in the present embodiment, under the same prompting level, the TTC critical value set on the passenger side is larger than that set on the main driver side, so that under the same vehicle coming condition, the prompting lamp on the passenger side is turned on in advance to prompt, thereby achieving a better safety prompting effect.
In specific implementation, the assistant driving side and the main driving side may use different pre-stored mapping tables, for example, the main driving side may use the pre-stored mapping table given in table 2, and the assistant driving side may use the pre-stored mapping table given in table 3 below:
table 3:
wherein, A is a first preset prompt level, B is a second preset prompt level, and C is a third preset prompt level. Compared with the tables 2 and 3, under the same condition, the prompting lamp on the copilot side is lightened for 0.5s in advance compared with the prompting lamp on the main driving side, so that the influence on the driver caused by the larger blind area on the copilot side can be well compensated, and the safety prompting effect is further improved.
Further, in some optional embodiments of the present invention, warning lights for respectively giving a safety prompt to two sides of a vehicle are disposed in a preset display in a cab, where the preset display is at least one of a center control screen, a head-up display, a car recorder, and an interior rearview mirror, and the method may further include:
and when the preset prompt level corresponding to the moving target is the first preset prompt level, controlling a warning lamp corresponding to one side of the preset display where the moving target is located to be lightened according to a preset lightening mode corresponding to the first preset prompt level for prompting.
When the safety prompting device is specifically implemented, a left warning lamp and a right warning lamp can be arranged on a central control screen, a head-up display, a vehicle data recorder or an inner rearview mirror (the central control screen or the head-up display is selected preferentially), the left warning lamp corresponds to the left warning lamp, the right warning lamp corresponds to the right warning lamp, when the preset prompting level corresponding to the moving target is a first preset prompting level (A level), the warning lamp and the prompting lamp on one side of the moving target simultaneously flicker in a high-frequency and high-brightness mode, so that the corresponding lightening prompting is carried out at the position of the significant position in the cab, and the safety prompting effect is further improved. The warning lamp and the prompting lamp can be LED lamps, so that the warning lamp and the prompting lamp have high controllability.
