Background
With the continuous development of science and technology, the requirements of drivers on automobiles are continuously improved, and the functions of automobiles in the intelligent field are continuously increased. In the conventional PEPS vehicle type, the function of powering on the vehicle or unlocking and locking the vehicle through a door handle is realized on the basis of intelligent key authentication; when the driver presses the start button SSB or presses the brake pedal, the vehicle authenticates the intelligent key, and if the intelligent key is authenticated, the vehicle can be electrified or started. However, the prior art does not deal with the effective duration of the smart key, nor does it consider the effect on the key effectiveness when the vehicle power state or the door state changes.
When a driver presses a start button SSB or steps on a brake, the authentication result of the vehicle on the intelligent key is valid; however, after authentication is completed, the key validity maintenance time cannot be too long or too short: if the maintenance time is too short, the intelligent key becomes invalid immediately after being valid, repeated and continuous authentication of the intelligent key can be caused, the vehicle battery and the intelligent key battery are lost, and other performances of the vehicle are affected; if the maintenance time is too long, after the driver leaves the vehicle door with the key, anyone can start the engine when getting on the vehicle in a state that the validity of the key is still maintained, and the risk of stolen vehicle exists. On the other hand, if only the smart key is used and the mechanical key cannot be used for powering up or starting the vehicle, the number of smart keys configured for each vehicle is limited, which results in poor user experience.

Detailed Description
The invention will be described in further detail with reference to the drawings and the detailed description.
The vehicle key detection system adopted for realizing the vehicle power-on starting key authentication and effectiveness processing method comprises a PEPS controller and a plurality of key detection antennae. The arrangement of the key detection antenna and the smart key detection area are shown in fig. 1, and the oval shadow area corresponding to the key detection antenna as the center is the smart key detection range of the key detection antenna. The method of the present invention may also be implemented using other types of key detection antenna arrangements and smart key detection areas.
Example 1:
referring to fig. 2, the method for authenticating and processing the validity of the key for power-on starting of the vehicle comprises the following steps:
judging the validity of the intelligent key when a brake pedal signal is detected to be stepped on or an SSB button is pressed, entering a preset mode if the intelligent key is valid, sending an in-vehicle key authentication request if the intelligent key is invalid, and entering the preset mode when the effective intelligent key exists in the vehicle; if no effective intelligent key exists in the vehicle and a signal of releasing a brake pedal is detected, the intelligent key is in an invalid state; if the signals of the start button SSB and the brake pedal release are not detected, the intelligent key is continuously authenticated until the intelligent key is in a valid state or the brake pedal is released.
The preset modes comprise a smart key validity delay mode, a default mode and a mechanical key validity mode; the switching of the preset mode is determined by the driver through the key selection, namely the post-triggering principle.
1. Respectively setting and prompting validity duration t of intelligent key under different preset modes
The first intelligent key validity duration of the intelligent key validity delay mode is an adjustable value, and the first intelligent key validity duration is preset to be 1h, 2h, … or nh through the corresponding time key; the validity duration of the second intelligent key in the default mode is a default value, and the second intelligent key in the default mode is preset to be the default value when the mode is selected through a default mode key; the validity time t of the intelligent key is set by pressing the corresponding time key, and the vehicle returns to the default mode when the default mode key is pressed.
And the third intelligent key validity duration of the mechanical key validity mode is a preset value. When the vehicle is in a non-mechanical key effective mode, long-time pressing of a central control unlocking key or other preset keys t1s which can be operated in an OFF gear of the vehicle causes the vehicle to enter the mechanical key effective mode; when the vehicle is in the mechanical key effective mode, exiting the mechanical key effective mode of the vehicle through the same operation; the default setting is restored to the default mode, and if the vehicle exits by setting the effective time of the intelligent key on the vehicle, the vehicle effectiveness delay mode is entered.
When in the smart key validity delay mode or the mechanical key validity mode, prompting the driver that the smart key validity maintenance time is modified or the mechanical key validity mode is entered comprises that four doors of the vehicle are in a closed state and loud speaker, and the vehicle machine displays that the vehicle is in a certain mode; until the driver clicks the "know" button, the car machine is no longer displayed and the horn is no longer loud.
2. And when the vehicle is electrified, the vehicle is electrified or the vehicle is powered off or the vehicle is started, the intelligent key is detected to judge the effectiveness of the intelligent key.
The smart key authentication flow is shown in fig. 3. The PEPS controller drives the key detection antenna to send a low-frequency signal, and the intelligent key sends a high-frequency signal to the PEPS controller after receiving the low-frequency signal.
The PEPS controller drives the key detection antenna to send low-frequency signals and the intelligent key to send high-frequency signals which contain key information. If the PEPS controller drives the key detection antenna to send the low-frequency signal which does not contain key information, the intelligent key does not send the high-frequency signal to the PEPS controller after receiving the low-frequency signal; if the high frequency signal sent by the smart key does not contain key information, the PEPS controller will not receive the high frequency signal. Therefore, the intelligent key detection method can effectively detect the intelligent keys bound by the vehicle, and can effectively prevent false detection of intelligent keys of other vehicles, thereby causing false unlocking operation.
2.1 Intelligent Key validity determination in Intelligent Key validity delay mode
When the vehicle is in the intelligent key effectiveness delay mode, a first timer starts to count; meanwhile, if any signal of opening the car door is identified, judging that the intelligent key is invalid, and stopping timing by the first timer; when the signals of all the doors are identified, judging that the intelligent key is effective, and continuing to count by the first timer, and allowing the vehicle to be started normally or locking or unlocking the vehicle when a mechanical key is used or not locked within the preset effective duration of the first intelligent key by the first timer.
2.2 Intelligent Key validity determination in default mode
When the vehicle is in the default mode, if any signal that the door and window of the vehicle is in the half-open state or the open state is detected, the validity duration of the second intelligent key is the minimum value for ensuring the normal power-on of the vehicle; when all doors and windows of the vehicle are closed and the state is unchanged, the validity duration of the second intelligent key is continuous to any one of the doors and windows of the vehicle, and an intelligent key signal is detected when the start button SSB signal or the brake signal is identified to be pressed for the first time; thereafter, the default smart key is in the vehicle (no matter how the driver operates in the vehicle, including pressing the start button SSB or stepping on the brake, etc.), the smart key validity is no longer detected, so as to reduce the smart key authentication times and the energy consumption of the vehicle battery and the smart key battery.
The judging mode of the validity of the intelligent key further comprises the following steps:
when the vehicle is in the smart key validity delay mode, if the vehicle is in the default mode, the first timer restarts counting (the timer 1 returns to 0 and counts again); if the intelligent key is not in the default mode, the first timer continues to count (the timer 1 does not return to 0 and continues to count), and continues to run the first timer until the intelligent key validity time reaches the preset first intelligent key validity duration, the intelligent key valid state is exited, if the brake pedal is identified to be released, the intelligent key invalid state is entered, and the states of the start button SSB and the brake pedal are judged again; if the brake pedal is not released, continuing to perform intelligent key authentication until the intelligent key is in a valid state or the brake pedal is released; when the vehicle is in the intelligent key effectiveness delay mode, if the vehicle is judged to be in the Start gear in real time, stopping the timing of the first timer and continuously judging whether the power gear exits from the Start gear; the first timer continues to count after exiting the gear.
If the vehicle is detected to be in a default mode in real time in the effective state of the intelligent key, if any door and window of the vehicle is identified to be opened (if a driver takes the intelligent key out of the vehicle, the timing of a first timer is not more than t, when someone enters the vehicle and presses a start button SSB by stepping on a brake, the engine is directly started to cause the vehicle to be stolen), or any door and window is changed into a signal of being completely closed from being opened, an in-vehicle key authentication request is sent, and the effective state of the intelligent key is maintained when the effective intelligent key in the vehicle is detected; if the intelligent key is not detected in the vehicle, judging whether a brake pedal is released or not; if the brake pedal is released, the intelligent key is in an invalid state, and the states of the starting button SSB and the brake pedal are judged again; if the starting button SSB and the brake pedal are not released, continuously detecting the intelligent key until the intelligent key is in an effective state or the brake pedal is released;
if the vehicle is detected not to be in the default mode in real time in the effective state of the intelligent key, and the vehicle enters the ineffective state of the intelligent key when any door or window of the vehicle is opened, the vehicle is forbidden to start; and if all doors and windows are detected to be closed in real time, entering an intelligent key effective state.
2.3 Intelligent Key validity determination in mechanical Key validity mode
Each vehicle is provided with 2 intelligent keys, each intelligent key is provided with a mechanical key, the intelligent keys and the mechanical keys can be used separately, and the vehicle can be started normally.

controlling all doors and windows of the vehicle to be in a locking state;
for the driver to unlock the vehicle using a mechanical key.
In t2 after the mechanical key is unlocked, setting the preset condition of the mechanical key to be satisfied (four doors are opened and a dangerous alarm lamp is opened), setting the condition in other options to be unsatisfied (a low beam high beam is closed), entering the effective state of the intelligent key, and starting the vehicle;
closing a vehicle door and entering an intelligent key invalid state;
the vehicle is started and normally runs.
If the mechanical key needs to be used again for power-on later, repeating the operation step of setting all preset conditions not to be met in t2 after the mechanical key is unlocked in the step, setting the preset conditions of the mechanical key to be met, setting the conditions in other options to be not met, and entering the effective state of the intelligent key at the moment.
Example 2:
in the other parts, in the same manner as in embodiment 1, if the driver sets the smart key validity time to 24 hours, then:
1. after the vehicle is started by using the intelligent key, the effectiveness of the intelligent key is maintained for 24 hours; therefore, the intelligent key is lost or is given to other people within 24 hours, and the vehicle still meets the requirements of users and is powered on and powered off normally;
2. if a non-driver needs to use a key string with the intelligent key, the intelligent key is not required to be taken down, and the validity time of the intelligent key is only required to be changed;
3. the driver can start the vehicle without the intelligent key; if the intelligent key is provided, the unlocking function and the vehicle starting function can be completed for the vehicle, and the vehicle can be normally used for 24 hours under the condition that the intelligent key is not provided.
