Description
Technical Field
The invention belongs to the field of vehicle remote control, and particularly relates to a method for remotely and temporarily authorizing keyless vehicle use.
Background
To use the vehicle normally, first, there must be a "key", which is a type that changes from day to day in the current rapid development of automobile technology, but no matter a physical key or a virtual key, such as: mechanical key, intelligent key, bluetooth key, APP remote control, face identification, its essence is all "use the mandate". When someone other than the vehicle owner needs to use the vehicle but does not have a key: the mechanical key and the intelligent key cannot cross over the space; the APP remote control has the problem that the APP remote control cannot directly take over locally; the Bluetooth key needs to download an application program of a corresponding vehicle type in advance and needs a sharing authority of a vehicle owner; face recognition requires a vehicle owner to add account information through an APP and assign usage rights. When a scenario is encountered that requires only temporary authorization for use, such as: the family needs to use the vehicle when going out, but does not have a key; a friend needs to use the vehicle temporarily, but does not have any authorization or key; the maintenance master has the advantages that the maintenance master can well find the vehicle problems for the user, but the user sometimes goes out to take away the key, and the vehicle is beside the maintenance master; the vehicle is anchored but the vehicle is in urgent need to leave, the vehicle is not locked and is not safe, and an insurance company can rescue the vehicle, but does not have a key after the vehicle is anchored. The scene that the user rights are tried to be handed over through the modes of a mechanical key, a smart key, a Bluetooth key, APP remote control and face recognition is particularly complex and time-consuming.
Disclosure of Invention
The invention aims to provide a method for remotely and temporarily authorizing keyless vehicle use, so that a temporary user can use the vehicle simply and conveniently.
The invention relates to a method for remotely and temporarily authorizing keyless vehicle use, which comprises the following steps:
when the intelligent vehicle body controller (IBCM) obtains a friend mode starting instruction, unlocking the whole vehicle, starting a friend mode (namely the whole vehicle enters a friend mode activation state), and respectively counting down for first preset time by the intelligent vehicle body controller and a vehicle machine (namely HU);
if the vehicle door is not opened within the second preset time, the intelligent vehicle body controller and the vehicle machine stop counting down, the intelligent vehicle body controller locks the whole vehicle, and the whole vehicle automatically exits from a friend mode;
if the door is opened within the second preset time, the car machine lights the display screen of the car machine, displays the countdown remaining time and prompts to start the engine within the countdown remaining time; in the remaining time of countdown, if the intelligent vehicle body controller acquires a one-key starting switch touch signal and a brake pedal depression signal, an engine starting request is sent to an engine management system, a countdown exiting request is sent to a vehicle machine, the intelligent vehicle body controller and the vehicle machine stop counting down, a display screen of the vehicle machine exits a countdown remaining time display interface, and the vehicle can be normally used (a temporary user can normally use the vehicle); when the countdown remaining time reaches 0, the display screen of the vehicle machine quits the countdown remaining time display interface, and if the intelligent vehicle body controller does not acquire a one-key starting switch touch signal and a brake pedal treading signal at the moment, the friend mode is closed;
in the normal use process of the vehicle, when the intelligent vehicle body controller does not acquire a friend mode closing instruction but acquires an engine extinguishing state signal, four vehicle doors closing state signals and a door handle locking switch touch signal, the whole vehicle is locked, and the whole vehicle automatically exits from a friend mode;
when the vehicle-mounted device acquires a friend mode closing instruction, prompting the vehicle owner to close the friend mode, and stopping starting the vehicle after flameout; the method comprises the steps that when an intelligent automobile body controller obtains a friend mode closing instruction, a friend mode is closed;
wherein the first preset time is longer than the second preset time; after the friend mode is closed, if the engine is in a turned-off state, the intelligent automobile body controller only acquires a one-key starting switch touch signal and a brake pedal treading signal, but does not detect a key signal, the intelligent automobile body controller does not send an engine starting request to an engine management system; after the friend mode is closed, the intelligent vehicle body controller locks the whole vehicle when acquiring a signal that the engine is in a turning-off state, a signal that the four doors are in a closing state and a signal that the door handle locking switch triggers.
In the normal use process of the vehicle, the intelligent vehicle body controller can start the engine again (without a key) as long as the door handle locking switch is not touched under the condition that a friend mode closing instruction is not obtained, even if the engine is extinguished. In the normal use process of the vehicle, under the condition that the instruction of closing the friend mode is obtained, if the engine is not extinguished, the intelligent vehicle body controller can be continuously used until the engine is extinguished after the vehicle is used, and the engine cannot be started (without a key) after the engine is extinguished.
Preferably, after the TSP background receives a friend mode starting control signal sent by the mobile terminal, when the power supply of the entire vehicle is judged to be OFF and the vehicle is in a fortifying state, a friend mode starting instruction is sent to a vehicle-mounted communication controller (namely, the T-BOX), and the vehicle-mounted communication controller forwards the friend mode starting instruction to the CAN bus. And the intelligent vehicle body controller and the vehicle machine acquire a friend mode starting instruction from the CAN bus. After receiving a friend mode closing control signal sent by the mobile terminal, the TSP background sends a friend mode closing instruction to the vehicle-mounted communication controller, and the vehicle-mounted communication controller forwards the friend mode closing instruction to the CAN bus. And the intelligent vehicle body controller and the vehicle machine acquire a friend mode closing instruction from the CAN bus.
Preferably, the first preset time is 2min, and the second preset time is 30 s.
After the method and the device are used, the vehicle owner can remotely control the APP to perform temporary authorization through the vehicle on the mobile terminal, so that the temporary user (such as family, friends, a maintenance master, a trailer master and the like) can conveniently and simply use the vehicle without using a key under the condition of not downloading the APP of the corresponding vehicle type, and the vehicle using experience is improved.
