When the driver sends out steering instruction operation, auxiliary voice prompt information is combined to start working. At least one traveling vehicle adjacent to the current vehicle is acquired by a detection system. The detection system may refer to a camera and radar integrated on the current vehicle; at least one running vehicle adjacent to the current vehicle is acquired through the camera and the radar. The traveling vehicle may refer to a vehicle adjacent to the current vehicle; for example, the adjacent vehicle on the left lane of the current vehicle, the adjacent vehicle on the right lane of the current vehicle, and the vehicle in which the lane in which the current vehicle is located are located in front of and behind the current vehicle.
The target vehicle comprises a vehicle which is adjacent to the current vehicle and is within a preset safety distance; the preset safe distance may refer to a safe driving distance of the adjacent vehicle on the roadway. The preset safe distance may refer to one thousandth of the current vehicle speed, for example, the running speed of the current vehicle is 60km/h, and the preset safe distance of the current vehicle is 60m.
As an alternative but non-limiting implementation, the determining at least one driving vehicle adjacent to the current vehicle and determining whether a target vehicle exists in the at least one driving vehicle includes, but is not limited to, steps A1-A3:
step A1: determining at least one driving vehicle on a current driving lane of the current vehicle and an adjacent lane; the adjacent lanes include a first travel lane to the left of the current travel lane and a second travel lane to the right of the current travel lane.
Step A2: and acquiring the running speed of the current vehicle, and determining a preset safe running distance according to the running speed of the current vehicle.

And determining the driving distance between the at least one driving vehicle and the current vehicle, and determining the target vehicle within the preset safe driving distance from the at least one driving vehicle. For example, the current vehicle is located in the rightmost lane of the driving lane; there are 10 running vehicles on the front, rear and left running roads of the current vehicle, the running distance between the 10 running vehicles and the current vehicle is acquired, and the running vehicle within the preset safe running distance is taken as the target vehicle.
S120, acquiring relative running information of the target vehicle and the current vehicle, and determining prompt tone information associated with the target vehicle according to the relative running information.
After determining the target vehicle within the preset safe driving distance, in order to avoid collision between the current vehicle and the target vehicle during the merging, a merging auxiliary sound prompt needs to be sent out to the current vehicle so as to reduce the condition that a driver looks at the rearview mirror or the screen in the vehicle and ensure the safety of the merging operation.

Alternatively, the alert sound may be an alert sound that is easily distinguished in the preset audio database. For example, the alert tone of the first adjacent vehicle on the left is A1, the alert tone of the second adjacent vehicle on the left is A2, and the alert tone of the first adjacent vehicle on the right is B1.
In another alternative of the embodiment of the present application, as shown in fig. 2, if the target vehicle does not exist within the preset safe driving distance of the current vehicle, the return detection system continues to determine whether the target vehicle exists within the preset safe driving distance of the current vehicle.

To the target vehicleThe relative driving distance of the current vehicle is normalized to obtain the prompt tone positioning distance associated with the target vehicle, wherein the normalization is as follows:
d n ＝1-exp(r n *(-1))
wherein d n To locate distance, r n Is the relative travel distance of the target vehicle and the current vehicle. r is (r) n The smaller d n The smaller.
And mapping the running speed of the target vehicle into a prompt tone envelope modulation frequency to generate a modulation prompt tone.

The magnitude of the modulation prompt tone frequency corresponds to the magnitude of the relative running speed of the target vehicle and the current vehicle; the alert tone information includes alert tone location distance, relative alert tone angle, and modulated alert tone. The faster the target vehicle running speed is relative to the current vehicle running speed, the higher the modulation frequency is, and the faster the frequency of the change in the warning tone value is.
S130, determining an audio signal output by the target audio prompt device according to the relative driving information, the prompt tone information and the audio prompt device deployment information of the current vehicle, and carrying out parallel auxiliary prompt on the current vehicle by adopting the audio signal.

Wherein, determining the deployment information of the voice prompt device of the current vehicle, referring to fig. 3, the voice prompt device of the current vehicle comprises S1, S2, S3 and S4; and determining at least two target voice prompt devices according to the relative running angle between the current vehicle and the target vehicle. For example, if the target vehicle is located at the upper right of the current vehicle, the target sound presentation apparatuses may be determined as S1 and S2.
And determining the sound power gain coefficient of the target sound prompting device based on a sound positioning method of vector synthesis amplitude translation according to the relative running information, the prompting sound information and the target sound prompting device deployment information of the current vehicle and the target vehicle. For example, taking an example in which the target vehicle is located between the target sound presenting devices S1 and S2, the sound power gain coefficient of the target sound presenting device is:
g 1n ＝d n *(cosβ n sinθ 2 -sinβ n cosθ 2 )/(cosθ 1 sinθ 2 -sinθ 1 cosθ 2 )
g 2n ＝d n *(cosβ n sinθ 1 -sinβ n cosθ 1 )/(cosθ 2 sinθ 1 -sinθ 2 cosθ 1 )
wherein g 1n Sound power gain for target sound prompting device S1Coefficient g 2n The sound power gain coefficient, beta, for the target sound alert device S2 n Theta is the relative driving angle or relative cue angle 1 For the angle θ of the position where the target sound prompting device S1 is located 2 The angle of the position of the target voice prompt device S2 is shown.
As an alternative but non-limiting implementation, the alert tone value gain factor of the target audio alert device includes:
and determining a prompt tone value gain coefficient of the target sound prompt device according to the running speed of the target vehicle and the relative running distance between the target vehicle and the current vehicle.

And determining the sound signal output by the target sound prompting device according to the sound power gain coefficient of the target sound prompting device, the prompting sound amplitude gain coefficient of the target sound prompting device and the modulation prompting sound of the target vehicle. The prompt tone value is adjusted according to the relative driving distance, and the closer the target vehicle is to the current vehicle, the larger the prompt tone value is. The prompt tone amplitude gain coefficient of the target sound prompt device is as follows:
a n ＝2^((v n /1000)/r n -1)
wherein a is n The cue tone amplitude gain coefficient for the target sound cue device.
As an optional but non-limiting implementation manner, the use of the sound signal to perform the auxiliary prompt for the current vehicle includes but is not limited to steps D1-D2:
step D1: at least two target voice prompt devices for carrying out parallel assistance on the current vehicle are determined, and voice signals output by the at least two target voice prompt devices are determined.
Step D2: after the current vehicle sends out the doubling instruction, the current vehicle is subjected to doubling prompt through sound signals output by the at least two target sound prompt devices.
Wherein, the target vehicle and the current vehicle are reflected by prompting the sound degree changeThe relative distance of the front traveling vehicle varies. Setting v according to automotive industry practice n And/1000 is a safe driving distance, namely one thousandth of the current speed (if the current vehicle speed is 60km/h, the safe distance is 60 m). A) when the relative driving distance of the target vehicle and the current vehicle is greater than the preset safe distance n Less than 1, does not send out the parallel line prompt tone; when the relative distance is smaller than the safety distance, a n If the number is larger than 1, a doubling prompting sound is sent out. Along with the reduction of the relative driving distance between the target vehicle and the current vehicle, the prompting sound volume gradually becomes larger, and the real-time dynamic prompting of the relative driving distance of the target vehicle can be realized. Output signal S of final mth target sound prompting device m-out The method comprises the following steps:
wherein S is m-out The sound signal output by the target sound prompting device is c, the number of the target vehicles is n, n is the nth target vehicle, and n is less than or equal to c. g mn The sound power gain coefficient for the mth target sound alert device.
After the output signal of the target voice prompt device is determined, when the current vehicle is in parallel connection, the output signal is adopted to carry out parallel connection auxiliary voice prompt on the current vehicle. For example, when there is a target vehicle on the right side of the current vehicle, the target sound alert devices located in the right front and right rear of the current vehicle will emit alert tones, and the sizes of the alert tones of the two target sound alert devices will be determined by the relative travel information and the relative alert tone information.
