Description

Technical Field

[0001] The present invention belongs to the technical field of vehicle key authentication, and in particular relates to a vehicle power-on start key authentication and validity processing method. Background Art

[0002] With the continuous development of science and technology, drivers' requirements for cars are constantly increasing, and the functions that cars can achieve in the field of intelligence are also increasing. At present, in commonly used PEPS models, the functions of powering on the vehicle or unlocking and locking the vehicle through the door handle are realized based on smart key authentication; when the driver presses the start button SSB or steps on the brake pedal, the vehicle authenticates the smart key. If the smart key is authenticated, it can be powered on or started. However, the existing technology does not deal with the validity period of the smart key, nor does it consider the impact of changes in the vehicle power status or door status on the key validity.

[0003] When the driver presses the start button SSB or steps on the brake, the vehicle's authentication result for the smart key is valid; but after the authentication is completed, the key validity maintenance time cannot be too long or too short: if the maintenance time is too short, the smart key will become invalid as soon as it becomes valid, which will lead to repeated and continuous authentication of the smart key, damage the vehicle battery and the smart key battery, and affect other performance of the vehicle; if the maintenance time is too long, when the driver walks out of the car door with the key, while the key validity is still maintained, anyone can get in the car and start the engine, which poses a risk of the car being stolen. On the other hand, if only the smart key can be used but the mechanical key cannot be used to power on or start the vehicle, due to the limited number of smart keys configured for each vehicle, it will lead to insufficient user use and a bad experience. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a vehicle power-on and start key authentication and validity processing method for maintaining the validity of a smart key for an appropriate length of time or using a mechanical key to complete the vehicle power-on and power-off or start function.

[0005] The technical solution adopted by the present invention to solve the above technical problems is: a vehicle power-on start key authentication and validity processing method, comprising the following steps:

[0006] When a brake pedal signal is detected or the SSB button is pressed, the validity of the smart key is determined. If it is valid, a preset mode is entered. If it is invalid, an in-vehicle key authentication request is issued. When a valid smart key is detected in the vehicle, the preset mode is entered again; the preset mode includes a smart key validity delay mode;

[0007] If no valid smart key is detected in the vehicle and the brake pedal is released, the vehicle enters the smart key invalid state; if no start button SSB and brake pedal release signal is detected, the smart key is continuously authenticated until the smart key is valid or the brake pedal is released;

[0008] When the vehicle is in the smart key validity delay mode, the first timer starts timing; at the same time, if a signal that any door is open is recognized, the smart key is judged to be invalid, and the first timer pauses timing; when a signal that all doors are closed is recognized, the smart key is judged to be valid, and the first timer continues timing. When the first timer reaches the preset first smart key validity period, the vehicle is allowed to be started normally, or the vehicle can be locked or unlocked using a mechanical key or when the vehicle is not locked.

[0009] According to the above scheme, the first smart key validity duration of the smart key validity delay mode is an adjustable value, which is preset to 1h, 2h, ..., or nh by key selection.

[0010] According to the above scheme, the preset mode also includes a default mode, for the driver to select one of the preset modes by pressing a button; the validity period of the second smart key in the default mode is a default value;

[0011] When the vehicle is in the default mode, if a signal is detected that any door or window is in a half-open or open state, the validity period of the second smart key is the minimum value to ensure normal power-on of the vehicle; when all doors and windows are closed and the state does not change, the validity period of the second smart key lasts until any door or window is opened, and the smart key signal is detected when the first SSB signal of pressing the start button or the brake signal is recognized; thereafter, it is assumed that the smart key is in the car and the validity of the smart key is no longer detected.

[0012] Furthermore, the validity determination method of the smart key also includes:

[0013] When the vehicle is in the smart key validity delay mode, if it is in the default mode, the first timer restarts the timing; if it is not in the default mode, the first timer continues to count, and continues to run the first timer until the smart key validity time reaches the preset first smart key validity time, then the smart key valid state is exited, and if it is recognized that the brake pedal has been released, the smart key invalid state is entered, and the status of the start button SSB and the brake pedal is judged again; if the brake pedal is not released, the smart key authentication is continued until the smart key valid state is entered or the brake pedal is released;

[0014] When the vehicle is in the smart key validity delay mode, if it is determined in real time that the power gear is in the Start gear, the timing of the first timer is paused and it is continuously determined whether the power gear exits the Start gear; after exiting the gear, the first timer continues timing.

[0015] Furthermore, if the vehicle is detected in real time to be in the default mode when the smart key is in the valid state:

[0016] If a signal that any door or window of the vehicle is open or any door or window changes from open to fully closed is identified, a request for in-vehicle key authentication is issued, and the smart key is maintained in a valid state when a valid smart key is detected in the vehicle; if no smart key is detected in the vehicle, it is determined whether the brake pedal has been released; if the brake pedal has been released, the smart key is in an invalid state, and the state of the start button SSB and the brake pedal is determined again; if the start button SSB and the brake pedal are not released, the smart key is continuously detected until the smart key is in a valid state or the brake pedal is released;

[0017] In the smart key valid state, if it is detected in real time that the vehicle is not in the default mode and any door or window of the vehicle is open, the smart key will enter the invalid state and the vehicle will be prohibited from starting; if it is detected in real time that all doors and windows are closed, the smart key will enter the valid state.

[0018] According to the above scheme, the preset mode also includes a mechanical key effective mode, for the driver to select one of the preset modes by pressing a button; the validity period of the third smart key in the mechanical key effective mode is a preset value;

[0019] When the vehicle is in the mechanical key valid mode and all the doors are locked, after it is recognized that the mechanical key has successfully unlocked the vehicle, the second timer starts timing, and firstly all the preset conditions in the mechanical key valid mode are set to be unsatisfied; when it is recognized that any of the preset conditions is satisfied within the validity period of the third smart key, the second timer stops timing, and it is re-determined whether the vehicle is in the mechanical key valid mode;

[0020] When it is identified that all the preset conditions are met within the third smart key validity period and the conditions of other options are not met, the smart key enters a valid state and the vehicle is allowed to be started; after entering the valid smart key state, if it is identified that any of the preset conditions is not met within the third smart key validity period, the smart key enters an invalid state, the vehicle is prohibited from being started, and the vehicle is re-detected whether it is in the mechanical key valid mode.

[0021] Furthermore, the steps of unlocking the vehicle using a mechanical key are:

[0022] Waiting for receiving a signal that the driver selects a mechanical key valid mode in a preset mode by pressing a key;

[0023] When in the mechanical key valid mode, all preset conditions are set to not be satisfied;

[0024] Control all doors and windows of the vehicle to be locked;

[0025] For the driver to unlock the vehicle using a mechanical key.

[0026] Further, the preset conditions include a main driver's door opened, a passenger door opened, a left rear door opened, a right rear door opened, hazard warning lights turned on, low beam lights turned on, and high beam lights turned on;

[0027] The situation where the preset condition is met is the state where the condition selected by the driver in the preset conditions is met;

[0028] The situation where the preset conditions are not met is a state where any one of the conditions selected by the driver among the preset conditions is not met;

[0029] The condition of other options being met is a state where any condition other than the condition selected by the driver among the preset conditions is met;

[0030] The situation where the conditions of other options are not satisfied is a state where all conditions other than the conditions selected by the driver among the preset conditions are not satisfied.

[0031] A vehicle key detection system comprises a controller, and the controller is used to complete a vehicle power-on start key authentication and validity processing method.

[0032] A computer storage medium stores a computer program executable by a computer processor, wherein the computer program executes a vehicle power-on start key authentication and validity processing method.

[0033] The beneficial effects of the present invention are:

[0034] 1. A vehicle power-on key authentication and validity processing method of the present invention enables the vehicle to enter a default mode, a key validity delay mode or a mechanical key validity mode through operation, and processes requests for key validity and key authentication in the corresponding mode according to changes in the vehicle's power state and door state, thereby achieving the function of maintaining the validity of the smart key for an appropriate length of time or using a mechanical key to complete the vehicle power on and off or start-up, effectively avoiding the risk of vehicle theft.

[0035] 2. The present invention avoids the risk that the key validity is maintained for too long, and the driver presses the start button SSB or steps on the brake pedal and immediately opens the door to leave the vehicle, resulting in anyone being able to start the engine and drive away the vehicle; at the same time, the validity of the smart key is processed according to the power gear, thereby avoiding the situation where the engine start time is long and the key validity is maintained for too short a time, resulting in the key validity being cleared and frequent key authentication, thereby avoiding the disadvantages of failure to successfully start the vehicle and accelerated battery consumption.

[0036] 3. The present invention sets the key validity maintenance time according to the actual scenario or the driver's intention, so that when the smart key is lost and only the mechanical key is available, the vehicle can still be started or shut down, thus avoiding the problem of being unable to start the vehicle after the smart key is lost. When entering the vehicle validity delay mode or the mechanical key validity mode, the vehicle prompts the driver until the driver presses the "known" button in the vehicle computer, ensuring that the driver understands the situation, avoiding the situation where the driver forgets to set a longer key validity maintenance time or set the mechanical key to be valid, resulting in the risk of the vehicle being started by others.

[0037] 4. The present invention detects the state of the vehicle brake or start button SSB in real time, authenticates the smart key when the conditions are met, and maintains the validity of the smart key if a valid smart key is detected. During the period of maintaining the key validity, the door and power gear status are detected in real time, and the key validity is cleared when certain conditions are met; or the smart key is authenticated again when certain conditions are met; ensuring that the key validity can be quickly cleared after the driver takes out the smart key.

[0043] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0044] The vehicle key detection system used to implement the vehicle power-on key authentication and validity processing method of the present invention includes a PEPS controller and a plurality of key detection antennas. The arrangement of the key detection antenna and the intelligent key detection area are as follows: Figure 1 As shown, the elliptical 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 can also be implemented by using other types of key detection antenna arrangements and smart key detection areas.

[0045] Embodiment 1:

[0046] See also Figure 2 A vehicle power-on start key authentication and validity processing method of the present invention comprises the following steps:

[0047] When the signal of the brake pedal being pressed or the SSB button being pressed is detected, the validity of the smart key is determined. If it is valid, the preset mode is entered. If it is invalid, a request for in-vehicle key authentication is issued. When a valid smart key is detected in the vehicle, the preset mode is entered again; if no valid smart key is detected in the vehicle and a signal of the brake pedal being released is detected, the smart key invalid state is entered; if no signal of the start button SSB and the brake pedal being released is detected, the smart key is continuously authenticated until the smart key valid state is entered or the brake pedal is released.

[0048] The preset modes include a smart key validity delay mode, a default mode and a mechanical key validity mode; the switching of the preset modes is determined by the principle of triggering after the driver selects a button.

[0049] 1. Set and remind the validity period of smart key in different preset modes

[0050] The first smart key validity period of the smart key validity delay mode is an adjustable value, which is preset to 1h, 2h,..., or nh through the corresponding time button selection; the second smart key validity period of the default mode is the default value, which is preset to the default value when the mode is selected through the default mode button; the smart key validity time t is set by pressing the corresponding time button, and the vehicle returns to the default mode when the default mode button is pressed.

[0051] The validity time of the third smart key in the mechanical key valid mode is the preset value. When the vehicle is in the non-mechanical key valid mode, long press the vehicle's central control unlock button or other preset buttons that can be operated in the OFF position for t1s, and the vehicle enters the mechanical key valid mode; when the vehicle is in the mechanical key valid mode, exit the vehicle mechanical key valid mode through the same operation; the default setting is restored to the default mode, and if you exit by setting the smart key valid time on the vehicle computer, you will enter the vehicle validity delay mode.

[0052] When in the smart key validity delay mode or the mechanical key validity mode, the driver is prompted that the smart key validity maintenance time has been modified or that the mechanical key validity mode has been entered, including the vehicle's four doors being closed, the horn sounding, and the vehicle computer displaying "the vehicle is in a certain mode"; until the driver clicks the "Known" button, the vehicle computer no longer displays and the horn no longer sounds.

[0053] 2. Perform smart key detection when the vehicle is powered on, powered off or started to determine the validity of the smart key.

[0054] For the smart key authentication process, see Figure 3 The PEPS controller drives the key detection antenna to send a low-frequency signal, and the smart key receives the low-frequency signal and sends a high-frequency signal to the PEPS controller.

[0055] The low-frequency signal sent by the key detection antenna driven by the PEPS controller and the high-frequency signal sent by the smart key both contain key information. If the low-frequency signal sent by the key detection antenna driven by the PEPS controller does not contain key information, the smart key will not send a 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 above-mentioned smart key detection method can effectively detect the smart keys that have been bound to the vehicle, and can effectively prevent the smart keys of other vehicles from being mistakenly detected, resulting in misinterpreted locking operations.

[0056] 2.1 Smart Key Validity Judgment in Smart Key Validity Delay Mode

[0057] When the vehicle is in the smart key validity delay mode, the first timer starts timing; at the same time, if a signal that any door is open is recognized, the smart key is judged to be invalid, and the first timer pauses timing; when a signal that all doors are closed is recognized, the smart key is judged to be valid, and the first timer continues timing. When the first timer reaches the preset first smart key validity period, the vehicle is allowed to be started normally, or the vehicle can be locked or unlocked using a mechanical key or when the vehicle is not locked.

[0058] 2.2 Smart Key Validity Judgment in Default Mode

[0059] When the vehicle is in the default mode, if a signal is detected that any door or window is in a half-open or open state, the validity period of the second smart key is the minimum value to ensure normal power-on of the vehicle; when all doors and windows are closed and the state does not change, the validity period of the second smart key lasts until any door or window is opened, and the smart key signal is detected when the first start button SSB signal or brake signal is identified; thereafter, it is assumed that the smart key is in the car (regardless of how the driver operates in the car, including pressing the start button SSB or stepping on the brake, etc.), and the validity of the smart key is no longer detected, so as to reduce the number of smart key authentication times and the energy consumption of the vehicle battery and the smart key battery.

[0060] The validity of the smart key is also determined by:

[0061] When the vehicle is in the smart key validity delay mode, if it is in the default mode, the first timer restarts (timer 1 returns to 0 and restarts timing); if it is not in the default mode, the first timer continues to count (timer 1 does not return to 0 and continues to count), and continues to run the first timer until the smart key validity time reaches the preset first smart key validity time, then exits the smart key valid state, if it is recognized that the brake pedal is released, enters the smart key invalid state, and judges the status of the start button SSB and the brake pedal again; if the brake pedal is not released, continues to authenticate the smart key until entering the smart key valid state or the brake pedal is released; when the vehicle is in the smart key validity delay mode, if it is determined in real time that the power gear is in the Start gear, pauses the timing of the first timer and continues to judge whether the power gear has exited the Start gear; after exiting the gear, the first timer continues to count.

[0062] In the smart key valid state, if it is detected in real time that the vehicle is in the default mode, if any door or window of the vehicle is open (if the driver takes the smart key outside the vehicle and the timing of the first timer is not greater than t, when someone enters the vehicle and presses the start button SSB while stepping on the brake, the engine is directly started, causing the vehicle to be stolen) or any door or window changes from open to completely closed, an in-vehicle key authentication request is issued, and the smart key valid state is maintained when a valid smart key is detected in the vehicle; if no smart key is detected in the vehicle, it is determined whether the brake pedal is released; if the brake pedal is released, the smart key is entered into the invalid state, and the states of the start button SSB and the brake pedal are determined again; if the start button SSB and the brake pedal are not released, the smart key is continuously detected until the smart key is entered into the valid state or the brake pedal is released;

[0063] In the smart key valid state, if it is detected in real time that the vehicle is not in the default mode and any door or window of the vehicle is open, the smart key will enter the invalid state and the vehicle will be prohibited from starting; if it is detected in real time that all doors and windows are closed, the smart key will enter the valid state.

[0064] 2.3 Intelligent key validity judgment in mechanical key valid mode

[0065] Each vehicle is equipped with two smart keys, each with a mechanical key. The smart key and the mechanical key can be used separately and can both start the vehicle normally. When the vehicle is in the mechanical key valid mode, the driver uses the mechanical key to start the vehicle. The mechanical key is equipped with a sensor to identify whether the mechanical key has been inserted into the vehicle lock hole.

[0066] The preset conditions in the effective mechanical key mode include the main driver's door opened, the passenger door opened, the left rear door opened, the right rear door opened, the hazard warning lights turned on, the low beam lights turned on, and the high beam lights turned on. The purpose of setting the preset conditions is to prevent others from using mechanical keys or illegal mechanical keys to open the door and start the vehicle, thereby avoiding the risk of theft; in actual applications, selecting different preset condition options and their permutations and combinations can obtain a variety of preset conditions to correspond to various actual application scenarios. This embodiment takes the preset conditions of "main driver's door opened, passenger door opened, left rear door opened, right rear door opened, hazard warning lights turned on" as an example to determine whether the vehicle is in the effective mechanical key mode.

[0067] The situation where the preset conditions are met is a state where the conditions selected by the driver among the preset conditions are met; the situation where the preset conditions are not met is a state where any one of the conditions selected by the driver among the preset conditions is not met; the situation where the conditions of other options are met is a state where any one of the conditions other than the conditions selected by the driver among the preset conditions is met; the situation where the conditions of other options are not met is a state where all the conditions other than the conditions selected by the driver among the preset conditions are not met.

[0068] See also Figure 4 , when the vehicle is in the mechanical key valid mode and all the doors are locked, after recognizing that the mechanical key has successfully unlocked the vehicle, the second timer starts timing, and firstly all the preset conditions in the mechanical key valid mode are set to be unsatisfied (four doors are closed and the hazard warning lights are off); when any of the preset conditions is recognized to be satisfied (any of the four doors is opened or the hazard warning lights are on) within the validity period of the third smart key, the second timer is stopped, and it is re-determined whether the vehicle is in the mechanical key valid mode;

[0069] When it is identified within the third smart key validity period that all the preset conditions are met and the conditions of other options are not met (four doors are open, the hazard warning lights are on, and the low beam and high beam are not on), the smart key enters a valid state and the vehicle is allowed to be started; after entering the smart key valid state, if it is identified within the third smart key validity period that any of the preset conditions is not met (any of the four doors is closed or the hazard warning lights are off), the smart key enters an invalid state, starting the vehicle is prohibited, and the vehicle is re-detected whether it is in the mechanical key valid mode.

[0070] The steps to unlock the vehicle using a mechanical key are as follows:

[0071] Waiting for receiving a signal that the driver selects a mechanical key valid mode in a preset mode by pressing a key;

[0072] When in the mechanical key valid mode, all preset conditions are set to not be met (four doors closed and hazard warning lights off);

[0073] Control all doors and windows of the vehicle to be locked;

[0074] For the driver to unlock the vehicle using a mechanical key.

[0075] Within t2 after the mechanical key is unlocked, set the mechanical key preset conditions to be satisfied (four doors open and hazard warning lights on), set the conditions in other options to be unsatisfied (low beam and high beam off), enter the smart key valid state, and start the vehicle;

[0076] Close the car door and enter the smart key invalid state;

[0077] The vehicle started and ran normally.

[0078] If you need to use the mechanical key to power on again later, repeat the steps "Set all preset conditions to not be satisfied" to step "Within t2 after the mechanical key is unlocked, set the mechanical key preset conditions to be satisfied and set the conditions in other options to not be satisfied". At this time, the smart key is in the valid state again.

[0079] Embodiment 2:

[0080] In the case where other parts are the same as those in Embodiment 1, if the driver sets the validity period of the smart key to 24 hours, then:

[0081] 1. After using the smart key to start the vehicle, the smart key will remain valid for 24 hours; therefore, if the smart key is lost or given to someone else within 24 hours, the vehicle can still be powered on and off normally to meet user needs;

[0082] 2. If a non-driver needs to use a keychain with a smart key, there is no need to remove the smart key, just change the validity period of the smart key;

[0083] 3. The driver can start the vehicle without the smart key; if the driver has a mechanical key, the vehicle can be unlocked and started, and the vehicle can be used normally 24 hours a day without the smart key.

[0084] Embodiment 3: The vehicle status conditions and time parameters in the technical solution can be set with alternative solutions, such as maintaining the validity of the smart key for t1, etc.; when these conditions change, the technical problems targeted by the present invention can also be solved and the beneficial effects of the present invention can be achieved.

[0085] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

[0086] The above embodiments are only used to illustrate the design ideas and features of the present invention, and their purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly. The protection scope of the present invention is not limited to the above embodiments. Therefore, any equivalent changes or modifications made based on the principles and design ideas disclosed by the present invention are within the protection scope of the present invention.
