[0048] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0049] Figure 1 This is a flowchart of a rear combination lamp control method provided in one or more embodiments of the present invention. See also... Figure 1 The control method for the rear combination lights includes the following operating steps:
[0050] S11 sets a safe following distance for vehicles behind.
[0051] S12 receives driving parameters transmitted from the following vehicle.
[0052] S13, based on driving parameters, determines whether the distance between the vehicle and the vehicle behind is within a safe distance.
[0053] S14, if the vehicle is outside the safe distance, project a safety following line at the corresponding position of the safe distance.
[0054] S15, if within a safe distance, project a safety following line at the front of the following vehicle.
[0055] The technical solution of this embodiment, by projecting a safety following line behind the vehicle, reminds the vehicles behind to pay attention to a safe following distance, which can effectively reduce the probability of rear-end collisions.
[0056] When implementing this method, it is first necessary to set a suitable safe following distance for the following vehicle.
[0057] The safe following distance setting needs to meet certain requirements. The primary requirement is to ensure the safety of the vehicle behind. This safe following distance setting should effectively alert drivers of vehicles behind to maintain a safe distance, thereby effectively preventing rear-end collisions.
[0058] The setting for safe following distance has a variable range. Settings within this range are valid. In other words, the safe following distance setting is allowed to adjust automatically within this variable range.
[0059] So, within the variable range, how to choose the setting value for the safe following distance needs to take into account factors such as the weather and the current driving speed.
[0060] For example, if the current weather is snowing, the safe following distance should be set slightly larger. If the current driving speed is very high, the safe following distance should also be set slightly larger.
[0061] Next, the driving parameters of the following vehicle are received. In this embodiment, the driving parameters mainly refer to the driving speed and geographical location of the following vehicle.
[0062] The aforementioned driving parameters of the following vehicle can be measured by the radar installed on the vehicle itself, or by the driving radar of the following vehicle, and then transmitted to the relevant controller of this vehicle.
[0063] After receiving the driving parameters from the vehicle behind, a basis for judging the distance between the two vehicles is established. In other words, it can now determine whether the distance between the two vehicles has exceeded the previously set safe following distance. It should be understood that when the distance between the two vehicles is greater than the safe following distance, the situation is safe, and no warning is needed. However, if the distance between the two vehicles is equal to or less than the safe following distance, the current situation is less safe, and a warning needs to be given to the driver of the vehicle behind.
[0064] In this embodiment, a safety following line is projected behind the vehicle to provide a safety reminder to the driver of the vehicle behind.
[0065] The projection of safe following lines is divided into two different methods. The first method is used when the distance between the vehicle and the vehicle behind does not exceed the safe following distance. If the distance between the vehicle and the vehicle behind does not exceed the safe following distance, the current distance can be considered safe. In this case, the safe following line is projected only at a predetermined distance behind the vehicle. That is to say, in the first projection method, the distance between the safe following line and the rear of the vehicle is a fixed value.
[0066] The second method is used when the distance between the vehicle and the vehicle behind has exceeded the safe following distance. If the distance between the vehicle and the vehicle behind has exceeded the safe following distance, the current distance is dangerous, and it is necessary to warn the driver of the vehicle behind by projecting a safe following line.
[0067] In the second projection method, the safety following line moves with the position of the front of the following vehicle. That is to say, the distance between the safety following line and the rear of the vehicle is not fixed, but rather the safety following line is projected wherever the front of the following vehicle is.
[0068] In addition to the variable-position safety following line, other auxiliary means can be added to alert the driver of the following vehicle and remind them to maintain a safe following distance.
[0069] These auxiliary methods could include projecting a high-brightness safety following line or illuminating one's own position lights, etc.
[0070] Figure 2 A schematic diagram of the safety following line projection under the first projection method is shown. See also Figure 2 In the first projection method, the distance between the vehicle in front and the vehicle behind is still large and does not exceed the safe following distance.
[0071] At this point, a safety following line is projected at a fixed position behind the vehicle. Furthermore, the distance between the projected safety following line and the rear of the vehicle remains constant.
[0072] Figure 3 A schematic diagram of the safety following line projection under the second projection method is shown. See also Figure 3 In the second projection method, the distance between the vehicle in front and the vehicle behind has exceeded the safe following distance.
[0073] At this point, the position of the safety following line projected behind the vehicle needs to be adjusted according to the position of the front of the following vehicle. In other words, the distance between the safety following line and the rear of the vehicle will change as the position of the front of the following vehicle changes.
[0074] Figure 4 This is a flowchart of a rear combination lamp control method provided in one or more embodiments of the present invention. See also... Figure 4 The control method for the rear combination lights includes the following operating steps:
[0075] S41 sets a safe following distance for vehicles behind.
[0076] S42 receives driving parameters transmitted from the following vehicle.
[0077] S43 determines whether the distance to the vehicle behind is within a safe distance based on driving parameters.
[0078] S44, if outside the safe distance, project the first preset prompt at the safe following line.
[0079] S45, if within a safe distance, projects a second set prompt at the safe following line.
[0080] In this embodiment, in order to warn the driver of the following vehicle, in addition to projecting a safety following line behind the vehicle, a prompt message is further projected at the location of the projected safety following line.
[0081] Setting warning words, also known as safety warning words, serves a similar purpose to following lane markings: to alert vehicles behind them of current safety risks.
[0082] Because the safety following line projection process is managed separately for two different scenarios, the projection of safety reminder messages also differentiates between these two scenarios.
[0083] When the following vehicle is at a safe distance, the projected safety warning word is called the first preset warning word, or the first safety warning word.
[0084] Since this is a relatively safe situation, the first setting prompt word was "safe".
[0085] When the following vehicle is within a safe distance, the projected safety warning message is called the second preset warning message, or the second safety warning message.
[0086] In this situation, a rear-end collision is very likely to occur. Therefore, the second warning message was set to "Keep a safe distance".
[0087] Increasing the projection of prompt words can more clearly alert drivers behind, thus more effectively preventing rear-end collisions.
[0088] In addition to adding prompts, you can also change the projection color to a more eye-catching color, increase the projection brightness, and so on to more noticeably remind drivers behind you.
[0089] Figure 5 and Figure 6 The images show the projection effect of the safety following line after adding the warning words. See also Figure 5 When the following vehicle is at a safe distance, a safety following line is projected at a fixed position. In addition, a first setting prompt word "safety" is projected at the location of the projected safety following line.
[0090] See Figure 6 When the vehicle behind is within a safe distance, a safety following line is projected at a variable position. In addition, a second warning message with the words "Caution: Distance" is projected at the location of the projected safety following line.
[0091] Figure 7 This is a flowchart of a rear combination lamp control method provided in one or more embodiments of the present invention. See also... Figure 7 The control method for the rear combination lights includes the following operating steps:
[0092] S71 sets a safe following distance for vehicles behind.
[0093] S72 receives driving parameters transmitted from the following vehicle.
[0094] S73 determines whether the distance to the vehicle behind is within a safe distance based on driving parameters.
[0095] S74, if outside the safe distance, project a safety following line at the corresponding position of the safe distance.
[0096] S75, if within a safe distance, will project a safety following line in a bright form at the front of the following vehicle.
[0097] In this embodiment, when a vehicle behind exceeds the safe distance set by this vehicle, this vehicle projects a safety following line to the rear using a high-brightness method.
[0098] The safety following lines projected using a high-brightness method are more conspicuous than ordinary safety following lines, providing a more obvious warning to drivers of following vehicles and more effectively preventing rear-end collisions.
[0099] Figure 8 The safety following line is shown in highlighted projection. See also Figure 8 The safety following lines projected in a high-brightness manner are more conspicuous than those projected in a normal manner, and their effect on alerting drivers of following vehicles is more obvious.
[0100] Figure 9 This is a flowchart of a rear combination lamp control method provided in one or more embodiments of the present invention. See also... Figure 9 The control method for the rear combination lights includes the following operating steps:
[0101] S91 sets a safe following distance for vehicles behind.
[0102] S92 receives driving parameters transmitted from the following vehicle.
[0103] S93 determines whether the distance to the vehicle behind is within a safe distance based on driving parameters.
[0104] S94, if outside the safe distance, project a safety following line at the corresponding position of the safe distance.
[0105] S95, if within a safe distance, control the position light to highlight.
[0106] In this embodiment, when a vehicle behind exceeds the safe distance set by this vehicle, this vehicle uses a bright position light to alert the driver of the following vehicle of the safety risk.
[0107] The use of high-brightness position lights to indicate safety risks is more eye-catching than ordinary headlights, providing a more obvious warning to drivers behind and more effectively preventing rear-end collisions.
[0108] It should be understood that the security risk warning method provided in this embodiment can be used in combination with other risk warning methods described in the foregoing embodiments of this application to improve the warning effect.
