Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
Unless otherwise specified, the front-rear direction in the present application is the longitudinal direction of the vehicle, i.e., the X direction; the left and right directions are the transverse direction of the vehicle, namely the Y direction; the up-down direction is the vertical direction of the vehicle, i.e., the Z direction.
The following describes an anti-rear-end collision system 100 for a vehicle according to an embodiment of the present invention with reference to fig. 1 to 4.
The rear-end collision prevention system 100 for a vehicle according to an embodiment of the present invention includes: detection means, presentation means 50 and control means.
As shown in fig. 1, the detecting device is suitable for being installed at the rear of the vehicle 101, and the detecting device may be a camera 10 and is used for detecting the operation information of the rear vehicle 102 so as to monitor the relative distance and the relative speed between the vehicle 101 and the rear vehicle 102 in real time. Therefore, the driver and the passenger can adjust the running state of the vehicle 101 in time according to the detection condition, thereby effectively preventing the rear-end collision of the vehicle 102.
The prompting device 50 is used for sending prompting signals to the vehicle 101 and the rear vehicle 102, so that when the vehicle 101 is prone to rear-end collision with the rear vehicle 102, the prompting device 50 can prompt people in the vehicle and send the prompting signals to a driver of the rear vehicle 102 at the same time, so that the people in the vehicle of the two vehicles can take measures for avoiding rear-end collision, the driving state of the vehicle 101 can be adjusted in time, and safe driving performance is improved.
The detection device and the prompt device 50 are electrically connected with the control device, that is, the detection device can transmit the detected running information of the rear vehicle 102 to the control device, and the control device can selectively trigger the prompt device 50 according to the detection information.
The control device is adapted to analyze the moment of contact distance between the vehicle 101 and the following vehicle 102 based on the operation information, and as shown in fig. 2 and 3, the control device is configured to control the prompting device 50 to be turned on when the moment of contact distance is smaller than a first set value, and not to trigger the prompting device 50 when the moment of contact distance is larger than a second set value. The first set value is a safe collision distance moment, the second set value is a dangerous collision distance moment, and the control device can compare the actual contact distance moment with the first set value and the second set value so as to more accurately determine whether the relative running state of the vehicle 101 and the rear vehicle 102 has the risk of rear-end collision.
As shown in fig. 3, the actual contact distance time between the vehicle 101 and the rear vehicle 102 is TTC (contact distance time), the first set value is TTC2, and the second set value is TTC 1. Thus, when TTC > TTC1, the actual contact distance time is greater than the safe collision distance time, under this relative operating condition, the occupants of both the front and rear vehicles 102 can make safe adjustments in time within a sufficient time, the control device does not trigger the prompting device 50, and both vehicles can run safely; when the TTC is less than TTC2, that is, the actual contact distance time is less than the dangerous collision distance time, that is, under the relative operation condition, if an accident occurs, the drivers and the passengers of both cars cannot make a safety adjustment in time to prevent the rear-end collision of the rear car 102, that is, the vehicle 101 has a risk of being rear-end collided by the rear car 102, at this time, the control device controls the prompting device 50 to be turned on to prompt the drivers and the passengers of the vehicle 101 and the rear car 102 to make a safety adjustment as soon as possible and in time, so as to effectively avoid the rear-end collision of the rear car 102, and improve the driving safety.
The TTC 1-TTC 2 are fluctuation ranges of time required for actually taking safety adjustment measures, and it can be understood that different vehicles 101 actually need different periods of time for performing rear-end collision prevention operation, and the actual contact distance time is compared with the TTC1 and the TTC2, so that drivers and passengers can be guaranteed to perform safety operation in time when the vehicles 101 with different braking systems and power systems are used.
According to the rear-end collision prevention system 100 for the vehicle, the running information of the rear vehicle 102 detected by the detection device is transmitted to the control device, and the control device can selectively trigger the prompt device 50 according to the detection information, so that the drivers and passengers of the vehicle 101 and the drivers and passengers of the rear vehicle 102 can be timely reminded of making safety adjustment, and meanwhile, the running state of the vehicle 101 can be timely adjusted, so that the running safety is effectively improved.
As shown in fig. 1, the detection device is used for detecting the relative distance and the relative speed between the rear vehicle 102 and the vehicle 101, and the actual contact distance time TTC between the vehicle 101 and the rear vehicle 102 is S/V (S represents the relative distance; V represents the relative speed), so that the control device can more accurately analyze the actual operation information of the rear vehicle 102 through the detection result of the detection device, so as to compare the actual operation information with the vehicle 101 in real time, and ensure that the vehicle 101 maintains a relatively safe state with the rear vehicle 102 at any time, thereby effectively improving the accuracy of the rear-end collision prevention system 100.
As shown in fig. 2, the actual contact distance moment of the first of the two rear vehicles 102 (the rear vehicle 102 in the middle of fig. 2) with the vehicle 101 is close to the safe collision distance moment, and at this time, the vehicle 101 and the first rear vehicle 102 are extremely easy to have the risk of rear-end collision; the actual contact distance moment of the second of the two rear vehicles 102 (the rear vehicle 102 on the right side of fig. 2) with the vehicle 101 approaches the dangerous collision distance moment, and at this time, the risk of rear-end collision between the vehicle 101 and the second rear vehicle 102 is unlikely to occur. Therefore, the detection device analyzes and compares the actual relative travel distance and speed of the vehicle 101 and the rear vehicle 102 to more accurately judge whether the vehicle 101 and the rear vehicle 102 have the possibility of rear-end collision or collision, so that the detection and control results of the rear-end collision prevention system 100 are closer to the actual state.
In some embodiments, as shown in fig. 1, the detection device includes a camera 10, the camera 10 is disposed in a middle area of a rear portion of a vehicle body of the vehicle 101, so that the camera 10 can clearly and comprehensively photograph the operation status of the rear vehicle 102, and distances between the camera 10 and left and right sides of the rear vehicle 102 are equal, so that accuracy of detection results of the two sides of the rear vehicle 102 is more balanced, a situation that the detection results are inconsistent due to non-uniform distance between the camera 10 and the left and right sides of the rear vehicle 102 is avoided, and accuracy of the detection device for detecting the operation information of the rear vehicle 102 is improved.
The camera 10 includes: a lens, an image sensor and a dynamic processor, wherein the lens and the image sensor are used for collecting the image information of the rear vehicle 102.
The image sensor and the dynamic processor are suitable for being electrically connected with the control device through a low-voltage differential signal cable, so that the image information of the rear vehicle 102 is transmitted to the dynamic processor, the dynamic processor processes the image information of the rear vehicle 102 and sends the processed information to the control device, and then the control device processes the received information to obtain the relative distance and the relative speed of the vehicle 101 and the rear vehicle 102.
In some embodiments, the control device includes an integrated controller 20 and a body controller 30,
as shown in fig. 4, the integrated controller 20 is electrically connected to the detection device, so that the integrated controller 20 can receive the operation information of the rear vehicle 102 collected by the detection device, and then the integrated controller 20 determines and analyzes the actual contact distance time according to the received operation information, and then compares the contact distance time with the first set value and the second set value to determine whether the rear-end collision risk exists between the vehicle 101 and the rear vehicle 102.
The integrated controller 20 is electrically connected with the vehicle body controller 30, and the integrated controller 20 is configured to output a control signal to the vehicle body controller 30, and the vehicle body controller 30 is adapted to control the prompting device 50 to selectively turn on after receiving the control signal. Thus, when TTC < TTC2, there is a risk that the vehicle 101 will be rear-ended by the following vehicle 102, the integrated controller 20 outputs a control signal to turn on the presentation device 50 to the vehicle body controller 30, and the vehicle body controller 30 controls the presentation device 50 to turn on upon receiving the control signal; when TTC > TTC1, the vehicle 101 is not in danger of being rear-ended by the rear vehicle 102, the integrated controller 20 outputs a control signal not to turn on the prompting device 50 to the vehicle body controller 30, and the vehicle body controller 30 does not trigger the prompting device 50 after receiving the control signal, so that the integrated controller 20 can selectively send out a prompting signal by controlling the prompting device 50 through the vehicle body controller 30 according to actual conditions, and it is ensured that a driver and an occupant can make safety adjustment in time.
The body controller 30 may be an original device of the vehicle 101, and does not need to be separately installed, which is beneficial to reducing the cost, for example, the body controller 30 is a driving member for turning on the voice speaker.
In some embodiments, the integrated controller 20 includes a housing and circuit components disposed within the housing, including an integrally disposed printed circuit board, flash memory chips, and a micro control unit. Therefore, the integrated controller 20 can temporarily store the operation information of the rear vehicle 102 collected by the detection device, and process the operation information of the rear vehicle 102, which is beneficial to improving the accuracy of the control device.
In some embodiments, the prompting device 50 includes: the automobile alarm comprises a sound prompt element and a light prompt element, wherein the sound prompt element is used for outputting alarm sound, and the light prompt element is used for outputting alarm light so as to prompt drivers and passengers of the automobile 101 and the rear automobile 102 from two visual and auditory angles, so that rear-end collision is effectively prevented, and the running safety of the automobile 101 is improved.
The sound prompting element comprises a voice loudspeaker arranged on the instrument desk, and can give out alarm sound through the voice loudspeaker to remind a driver and passengers in the vehicle 101 to make safety adjustment; the light prompting element comprises a tail lamp arranged at the rear part of the vehicle body, so that when the tail lamp is lightened, a driver and passengers of the rear vehicle 102 can be reminded to make safety adjustment, and then rear-end collision is effectively prevented, and the driving safety of the vehicle is effectively improved.
In some embodiments, the rear-end collision avoidance system 100 for a vehicle further comprises: the power supply 40 is controlled.
The detection device and the control device are both electrically connected with the control power supply 40, and the control power supply 40 is set to control the detection device and the control device to be started after the vehicle 101 is powered on, so that the control power supply 40 can control the detection device and the control device to be started when the vehicle 101 runs; when the vehicle 101 is parked, the control power source 40 is turned off to make both the detection device and the control device in the off state, and the operating states of the detection device and the control device are flexibly switched, thereby improving the rationality of the rear-end collision prevention system 100 for a vehicle.
The invention also provides a vehicle.
According to the vehicle provided by the embodiment of the invention, the rear-end collision prevention system 100 for the vehicle is arranged, the running information of the rear vehicle 102 detected by the detection device is transmitted to the control device, and the control device can selectively trigger the prompt device 50 according to the detection information, so that the running information of the rear vehicle 102 can be timely reminded for the driver and the passenger of the vehicle 101, and therefore the driver and the passenger of the rear vehicle 102 can timely adjust the running of the vehicle 101, and the running safety performance is effectively improved.
