As shown in fig. 2, the method comprises the steps of:

in step 201, in response to receiving a steering instruction for a target vehicle, a first turn-on instruction is sent to a signal receiver installed on the target vehicle, wherein the first turn-on instruction is used for instructing the signal receiver to receive signals transmitted by other vehicles.

In the exemplary embodiment of the present application, a target vehicle is installed with a left turn light and a right turn light, the left turn light corresponds to one turn control, and the right turn light corresponds to one turn control. In response to a driver of the target vehicle selecting an instruction of a steering control corresponding to any one of the steering lamps, the electronic equipment receives a steering instruction aiming at the target vehicle. The target vehicle is also provided with a signal receiver, the signal receiver is used for receiving signals transmitted by other vehicles, and the signal receiver and the electronic equipment are in communication connection through a wired network or a wireless network. The signal receiver may be installed at any position on the target vehicle, which is not limited in the embodiments of the present application. Illustratively, the signal receiver is mounted in front of the target vehicle. In response to the electronic equipment receiving a steering instruction for the target vehicle, the electronic equipment sends a first opening instruction to the signal receiver, so that the signal receiver opens the signal receiver based on the first opening instruction, and further receives signals transmitted by other vehicles.

Optionally, in response to the navigation application installed in the electronic device, the navigation application is configured to acquire a navigation route, so that the electronic device displays the navigation route, and further, the target vehicle travels according to the navigation route. When the running state of the navigation application program is running, acquiring a navigation route in the navigation application program, acquiring the current position of the target vehicle, and determining whether the target vehicle needs to turn or not based on the current position of the target vehicle and the navigation route. When the target vehicle needs to be steered, the navigation application program sends a steering instruction for the target vehicle to the electronic equipment, and the electronic equipment acquires the steering instruction.

A distance between a location at which the target vehicle is currently located and a location at which the target vehicle needs to be steered is determined. And determining that the target vehicle needs to be steered in response to the current position of the target vehicle being behind the position where the target vehicle needs to be steered and the distance between the current position of the target vehicle and the position where the target vehicle needs to be steered being less than a distance threshold.

In response to the current location of the target vehicle being ahead of the location where the target vehicle needs to turn, it is determined that the target vehicle does not need to turn. In response to the target vehicle being currently located behind the location where the target vehicle needs to turn, but the distance between the location where the target vehicle is currently located and the location where the target vehicle needs to turn being not less than the distance threshold, it is determined that the target vehicle does not need to turn.

Since location B is behind location a, it is determined that the target vehicle requires steering in response to the distance between location a and location B being less than the distance threshold. In the graph (2) of fig. 3, the position where the target vehicle is currently located is position C, the position where the target vehicle needs to turn is position B, and since position C is ahead of position B, it is determined that the target vehicle does not need to turn.

The target vehicle is also provided with a signal transmitter, the electronic device and the signal transmitter are in communication connection through a wired network or a wireless network, and the signal transmitter can be arranged at any position of the target vehicle. Illustratively, the signal transmitter is mounted in front of the target vehicle. In response to receiving a steering instruction for the target vehicle, the electronic device sends a second turn-on instruction to the signal transmitter, wherein the second turn-on instruction is used for instructing the signal transmitter to transmit a second signal with the target frequency. And after the signal transmitter receives the second starting instruction, the signal transmitter is started, and a second signal with the frequency as the target frequency is transmitted outwards through the signal transmitter. Wherein, the radiation length of the second signal emitted by the signal emitter can reach 100 meters.

The target frequency is any frequency in a frequency interval of 50 Hz to 80 Hz. For example, the target frequency is 60 hertz.

It should be noted that the first open command and the second open command may be the same command or two different commands, which is not limited in this embodiment of the application. After receiving a steering instruction for a target vehicle, a first opening instruction and a second opening instruction may be sent at the same time, or the first opening instruction may be sent to a signal receiver first, and then the second opening instruction is sent to a signal transmitter, or the second opening instruction may be sent to the signal transmitter first, and then the first opening instruction is sent to the signal receiver.

Alternatively, in response to the absence of the second signal having the target frequency from the at least one first signal, the travel speed of the target vehicle need not be controlled. In response to the presence of a second signal having a target frequency in the at least one first signal, the travel speed of the target vehicle is controlled in accordance with the following procedure.

In response to the current running speed not being greater than the target running speed, the running speed of the target vehicle does not need to be controlled. In response to the current travel speed of the target vehicle being greater than the target travel speed, the travel speed of the target vehicle is adjusted from the current travel speed to the target travel speed for the target duration.

The target running speed may be a fixed running speed set based on experience. Illustratively, the target travel speed is 40 km/h. The target running speed is a running speed determined based on the position where the target vehicle is currently located. Alternatively, the driving road on which the target vehicle is located is determined based on the current position of the target vehicle, and the driving speed corresponding to the driving road on which the target vehicle is located is taken as the target driving speed.

In one possible implementation, there are two implementations that determine the target travel speed based on the current location of the target vehicle.

In the first implementation manner, the electronic device stores the corresponding relationship between the driving road and the road state and the corresponding relationship between the road state and the driving speed. The electronic equipment determines the target running speed based on the current position of the target vehicle, the corresponding relation between the running road and the road state, and the corresponding relation between the road state and the running speed.

		Road one	Sparse state
Road two	Congestion status
		Road three	Sparse state

As can be seen from the first table, when the driving road is a first road, the corresponding road state is a sparse state. When the driving road is other, the corresponding road state is shown in the table one, which is not described herein again.

The first table is only an exemplary corresponding relationship between the driving road and the road state provided in the embodiment of the present application, and is not limited thereto.

The road state of the travel road may be determined based on the number of vehicles traveling on the travel road in a certain time period, and when the number of vehicles traveling on the travel road in a certain time period exceeds a number threshold, the road state of the travel road is determined to be a congestion state. And when the number of vehicles running on the running road in a certain time period does not exceed the number threshold, determining that the road state of the running road is a sparse state.

The number threshold is set based on experience, or adjusted according to a driving road, which is not limited in the embodiment of the present application. Illustratively, the quantity threshold is 50. A certain time period refers to any time period in a day, which is not limited in the embodiments of the present application. For example, a time period is 12:00-14:00 of a day.

The following table two shows a table of a corresponding relationship between a road state and a driving speed provided in the embodiments of the present application.

		Congestion	40 km/h
Sparse	50 km/h

As can be seen from the second table, when the road state is the congestion state, the corresponding running speed is 40 km/h; when the road state is sparse, the corresponding driving speed is 50 kilometers per hour.

It should be noted that the second table is only an exemplary corresponding relationship between a road state and a driving speed provided in the embodiment of the present application, and the road state may have more states, which is not limited in the embodiment of the present application.

In the second implementation manner, the server stores the corresponding relation between the driving road and the road state and the corresponding relation between the road state and the driving speed, and the electronic device acquires the target driving speed by sending a speed acquisition request to the server.

In a possible implementation manner, after acquiring the current position of the target vehicle, the electronic device generates a speed acquisition request based on the current position of the target vehicle, where the speed acquisition request carries the current position of the target vehicle, and the speed acquisition request is used for acquiring the target running speed. The electronic device sends the speed acquisition request to the server. And the server receives the speed acquisition request, analyzes the speed acquisition request and obtains the current position of the target vehicle. The server determines a driving road where the target vehicle is located based on the current position of the target vehicle. The server determines the road state of the driving road on which the target vehicle is located based on the driving road on which the target vehicle is located and the corresponding relationship between the driving road and the road state. And determining the running speed of the running road on which the target vehicle is located based on the road state of the running road on which the target vehicle is located and the corresponding relation between the road state and the running speed. The server sends the running speed of the running road where the target vehicle is located to the electronic device, and the electronic device obtains the running speed of the running road where the target vehicle is located, namely obtains the target running speed.

Any one of the above-described implementations may be selected to determine the target travel speed, which is not limited in the embodiment of the present application.

Alternatively, the target duration may be a fixed duration, for example, the target duration is 30 seconds. Of course, the target duration may also be determined based on a target distance between the target vehicle and the vehicle transmitting the second signal. Wherein the manner of determining the target distance between the target vehicle and the vehicle transmitting the second signal comprises: the signal strength of the second signal is determined, and the distance corresponding to the signal strength of the second signal is taken as the target distance between the target vehicle and the vehicle transmitting the second signal.

In a possible implementation manner, one signal strength corresponds to one distance, and the electronic device stores a corresponding relationship between the signal strength and the distance. The electronic device determines a signal strength of the second signal based on the signal strength determination component, and takes a distance corresponding to the signal strength of the second signal as a target distance between the target vehicle and the vehicle that transmitted the second signal.

As shown in the following table three, a table of correspondence between signal strength and distance provided in the embodiments of the present application is shown.

It should be noted that the third table is only an exemplary corresponding relationship between the signal strength and the distance provided in the embodiment of the present application, and is not limited thereto. The signal strength is inversely proportional to the distance, with higher signal strength corresponding to shorter distances and lower signal strength corresponding to longer distances.

Illustratively, the signal strength of the second signal is determined to be 60, and the target distance between the target vehicle and the vehicle transmitting the second signal is determined to be 80 meters based on the signal strength of the second signal and table three above.
