Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.
It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of exemplary embodiments according to the invention. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, and it should be understood that when the terms "comprises" and/or "comprising" are used in this specification, they specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof, unless the context clearly indicates otherwise.
The vehicle OBD interface is a hardware interface reserved on a vehicle-mounted computer, and can acquire running information such as the speed, the rotating speed, the water temperature and the like of a vehicle. The vehicle-mounted computer is internally provided with a vehicle-mounted diagnosis system, the running state of the vehicle is judged by utilizing information such as vehicle speed, rotating speed, water temperature and the like, a warning is given out when the vehicle is in fault, an OBD (On-Board Diagnostic) interface (short for OBD) is reserved On the vehicle-mounted computer for facilitating a maintenance worker to process the vehicle fault, and the maintenance worker can grasp the state of the vehicle after connecting the vehicle by utilizing a computer or other hardware equipment through the OBD interface, so that the debugging and the maintenance are facilitated.
As described in the background art, in a state where a vehicle is locked, remote unlocking needs to be performed by using the T-BOX, and unlocking needs to be performed by issuing an instruction through a background system after the T-BOX is networked, and if the vehicle is located in an area with weak signal coverage, the vehicle cannot be connected to a network, and further cannot be unlocked.
It should be noted that the locked state mentioned in this embodiment refers to a state in which the engine speed of the vehicle is limited, and in this state, the functions of each component of the vehicle, such as the door and the engine, can be normally started, and only the engine speed is limited. Accordingly, the unlocked state refers to a state in which the engine is released from the rotational speed restriction.
Therefore, the following embodiments provide a terminal emergency unlocking method and device and a motor vehicle, and the vehicle is unlocked only by using TBOX hardware in combination with the vehicle state, so that the situation that unlocking cannot be performed due to signal problems is avoided.
The first embodiment is as follows:
as shown in fig. 1, an emergency terminal unlocking method includes the following steps:
the TBOX is connected through a vehicle OBD interface, and a vehicle-mounted computer is powered on;
repeatedly disconnecting and connecting the built-in battery of the TBOX and the antenna for a set number of times within a set time period according to the unlocking condition;
if the unlocking condition is met, the TBOX sends an unlocking message to the vehicle-mounted computer, the vehicle-mounted computer is powered on again after the power is off for a set time period, and the vehicle is unlocked.
And if the unlocking condition is not met, the vehicle-mounted computer is powered on again after the power is off for a set time period, and the built-in battery and the antenna of the TBOX are repeatedly disconnected and connected for a set number of times.
If the unlocking condition is met, the TBOX stores an emergency unlocking record once, and the accumulated emergency unlocking times are not more than three times.
And repeatedly disconnecting and connecting the built-in TBOX battery and the antenna for a set number of times in at least 30 seconds.
The set number of times of repeated disconnection and connection of the internal battery is at least three times.
The set number of times of repeatedly disconnecting and connecting the antenna is at least five times.
The method also comprises the steps of acquiring the water temperature of the vehicle, and repeatedly disconnecting and connecting the built-in battery and the antenna of the TBOX for the set times after the water temperature reaches the set temperature.
If the unlocking condition is met, a GPS indicator light and a GSM indicator light of the TBOX twinkle.
The method comprises the following specific steps:
TBOX is connected through an OBD interface of the vehicle to power up the vehicle T15 (send a power supply ignition wire number to the vehicle-mounted computer to wake up the vehicle-mounted computer).
And (3) detaching the TBOX shell at the water temperature of at least 40 ℃, and plugging and unplugging the built-in battery for 3 times and the antenna for 5 times within 1 minute. The water temperature of 40 ℃ can be realized by starting the engine (in the locking state of the embodiment, the engine can be normally started, and only the rotating speed of the engine is limited)
Judging whether an unlocking condition is met, if so, adding 1 to the emergency unlocking times, unlocking for 3 times at most, sending an unlocking message, and after sending the unlocking message, displaying a switching-on state by the TBOX through two LED lamps, wherein the two lamps flicker in a green light mode; if the unlocking condition is not met, the T15 is electrified for one minute and then is electrified again for operation.
And powering off the whole vehicle T15 for 1 minute, and unlocking the vehicle after powering on again.
The method is only carried out on TBOX hardware, and unlocking is carried out under certain conditions by combining the state of the whole vehicle, and the method is simple and suitable for unlocking in an emergency state when TBOX cannot be connected with a network due to weak signals.
The number of times of emergency unlocking is stored in the TBOX terminal so as to limit the number of times, and unlimited repeated unlocking of the vehicle can be prevented. If the unlocking accumulated times reach a set value, resetting of the unlocking times can be carried out through remote operation of a platform (namely a mobile phone APP) of the vehicle network system after unlocking.
Whether to send the unlocking message or not is displayed through two LED lamps (GPS and GSM), and the unlocking message is more visual.
Example two:
the embodiment provides a terminal emergency unlocking device for implementing the unlocking method, which includes: TBOX and vehicle computer connected through OBD interface.
Example three:
the embodiment provides a motor vehicle equipped with the emergency unlocking device described in the second embodiment.
