The vehicle seeking signal control method in the embodiment of the application, as shown in fig. 1, includes the signal activation steps of:
step S101: in response to a vehicle parking operation, or
Responding to an in-vehicle routing unit activation signal from the mobile terminal;
step S102: and activating the vehicle-mounted routing unit to send out a routing signal, and forming a vehicle-mounted routing signal field around the vehicle. According to the embodiment of the application, a vehicle parking operation or a vehicle routing unit activation signal sent by a mobile terminal is used as a trigger condition for activating the vehicle routing unit to send out a routing signal, and after the vehicle routing signal is excited, a vehicle routing signal field is formed around a vehicle and used for vehicle searching of the mobile terminal.
Specifically, after the vehicle is parked or the vehicle-mounted routing unit activation signal of the mobile terminal is received, whether the vehicle meets the vehicle-mounted routing unit activation condition can be judged, and if the vehicle meets the vehicle-mounted routing unit activation condition, the step S102 is executed to activate the vehicle-mounted routing unit, so that energy waste caused by activation of the vehicle-mounted routing unit when the vehicle does not need to be searched is avoided. For example, if the vehicle is parked in a fixed parking space, the vehicle-mounted routing unit does not need to be activated after parking operation; and receiving the vehicle-mounted routing unit activation signal of the mobile terminal in the vehicle driving process, wherein the vehicle-mounted routing unit does not need to respond.
The vehicle-mounted routing unit comprises a first router 201, a second router 202 and a third router 203 which are dispersedly installed on a vehicle body; as shown in fig. 2, the first router 201, the second router 202, and the third router 203 are installed on the vehicle body in a spatially triangular manner.

activating the first router 201 to send out a first routing signal;
activating the second router 202 to issue a second routing signal;

In the semi-open space of the parking lot, the range of the routing signal field can at least cover the range of at least 300m around the vehicle body, and the coverage range of the routing signal field can be enlarged through an external antenna so as to improve the vehicle searching range.
The vehicle-mounted routing unit provided with the three routers generates a routing signal field comprising three routing signals, and the mobile terminal enters the routing signal field and can determine the specific position of the vehicle according to the signal intensity of the three routing signals.
According to the vehicle searching signal control method, the vehicle-mounted routing signal field is sent by the vehicle-mounted routing unit and used for searching vehicles at the mobile terminal, signals of the vehicle-mounted routing signal field are stable, the whole vehicle searching process does not depend on external signals, and the vehicle searching signal control method is suitable for searching vehicles on any occasions.

and if the intensity of the current positioning signal is smaller than the set intensity threshold value, activating the vehicle-mounted routing unit to send out a routing signal, and forming a vehicle-mounted routing signal field around the vehicle. The judgment of the vehicle parking operation can be carried out by stopping the engine, closing the vehicle door, and/or enabling the distance between the vehicle key and the vehicle to be larger than the set distance. After the vehicle stops, the judgment of the current positioning signal strength is the judgment of whether the vehicle meets the activation condition of the vehicle-mounted routing unit in the embodiment. After the vehicle is parked, whether the current positioning signal reaches a set intensity threshold value or not is judged, the current positioning signal is a GPS positioning signal, when the intensity of the GPS positioning signal is smaller than the set intensity threshold value, the current positioning signal is weak, the risk of positioning difficulty exists, at the moment, a vehicle-mounted routing unit is activated, a vehicle-mounted routing signal field is sent out, and a driver can use a vehicle key, a mobile phone and other mobile terminals to search the vehicle through the vehicle-mounted routing signal field.
In the embodiment of the application, after the vehicle is parked, whether the vehicle-mounted routing unit is activated is determined by judging the strength of the current positioning signal, and the vehicle-mounted routing unit is activated to send the vehicle-mounted routing signal field only in the parking lot with the weaker current positioning signal, so that the energy waste is avoided.

The vehicle-mounted routing unit activation signal can be sent by a driver operating the mobile terminal, or can be automatically sent by triggering the mobile terminal after meeting a set condition. As an example, the mobile terminal is a smart key, and the vehicle routing unit activation signal may be automatically sent out when the mobile terminal cannot detect the vehicle positioning signal, or the vehicle routing unit activation signal may be sent out by a driver operating the smart key.
In the embodiment of the application, after receiving the vehicle-mounted routing unit activation signal from the mobile terminal, the determination of whether the vehicle is shut down is the determination of whether the vehicle meets the vehicle-mounted routing unit activation condition in the foregoing embodiment. After receiving the vehicle-mounted routing unit activation signal from the mobile terminal, whether the vehicle is in a flameout state needs to be judged, if the vehicle is not flameout at the moment, the requirement of vehicle searching is not met, the vehicle-mounted routing unit activation signal sent by the mobile terminal is an invalid signal, and the vehicle-mounted routing unit does not respond to the invalid signal.
According to the embodiment of the application, after the vehicle-mounted routing unit activation signal of the mobile terminal is received, whether the vehicle is in a flameout state or not is judged to determine whether the vehicle-mounted routing unit is activated or not, the response to misoperation of the mobile terminal is prevented, and energy waste is avoided.

and after receiving a feedback signal from the mobile terminal, the vehicle-mounted routing unit periodically sends out a routing signal at a second frequency, wherein the second frequency is greater than the first frequency.
In the embodiment of the application, after a vehicle stops, the vehicle-mounted routing unit sends out routing signals periodically at a first frequency, and when the mobile terminal searches for the vehicle, a feedback signal is sent to the vehicle when the mobile terminal acquires the routing signals sent out by the corresponding vehicle. After the vehicle receives the feedback signal from the corresponding mobile terminal, the fact that the driver is searching the vehicle is indicated, and the vehicle-mounted router sends out the routing signal at the second frequency which is greater than the first frequency, so that the driver can search the vehicle conveniently. Before and after receiving the feedback signal from the mobile terminal, the vehicle-mounted routing unit sends out routing signals at different frequencies, so that the energy consumption of the vehicle can be saved before the driver searches the vehicle, and the signal intensity during vehicle searching can be ensured.

step S404: the onboard routing unit is turned off.
The embodiment of the application provides three control methods for closing a vehicle-mounted routing unit: one is to automatically shut down the on-board routing unit when the vehicle is started. And secondly, the vehicle-mounted routing unit is closed after a vehicle-mounted routing unit closing signal of the mobile terminal is received, namely, the driver controls the vehicle-mounted routing unit to be closed through the mobile terminal. And thirdly, the vehicle-mounted routing unit is automatically closed when the activation time reaches a set time threshold, the set time threshold can be set to be 24 hours, which is equivalent to the set maximum activation time of the vehicle-mounted routing unit, and the vehicle-mounted routing unit is automatically closed when the activation time exceeds the maximum activation time, so that the energy-saving effect is achieved.
