Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

The vehicle antenna arrangement and key detection area of the embodiment of the present invention are shown in fig. 1. The key detection range of the antenna is the area of the ellipse shadow corresponding to the antenna as the center. The invention focuses on the function implementation method, and is not limited to the system.

Referring to fig. 6, the specific steps of the embodiment of the present invention include:

1. key detection process

Referring to fig. 2, the key detection means that the PEPS controller drives the antenna to transmit a low-frequency signal, and after receiving the low-frequency signal, the key transmits a high-frequency signal to the PEPS, so that the detection process of the key bound to the vehicle is completed.

Before detecting the key, the key and the PEPS corresponding to the vehicle need to be mutually learned, and key information is stored, so that a foundation is laid for subsequently sending low/high frequency signals. The low-frequency signal sent by the PEPS drive antenna and the high-frequency signal sent by the key contain the key information. If the low-frequency signal sent by the PEPS drive antenna does not contain the key information, the key receives the low-frequency signal and does not send a high-frequency signal to the PEPS controller; if the high-frequency signal sent by the key does not contain the key information, the PEPS does not receive the signal; therefore, the key detection method can effectively detect the intelligent key bound by the vehicle and can effectively prevent the intelligent keys of other vehicles from being detected by mistake to cause the wrong unlocking operation.

The PEPS controller drives the antenna to transmit a low-frequency signal, and the transmission area range of the PEPS controller is the key detection area of the antenna (shown in fig. 1).

2. The key does not prompt the status explanation in the car:

the invention is totally provided with 3 keys which do not prompt the state in the vehicle:

the key does not prompt a first state in the vehicle: the driver presses a key start switch for the first time, the operation is the power-on intention of the vehicle, no intelligent valid key corresponding to the vehicle is detected in the vehicle at the moment, and the key is not in the vehicle at the moment to prompt a first state. At this time, a blinking prompt of "please put the valid key in the car" with frequency f1 appears on the meter screen, and the prompt time is t 1. (depending on the manufacturer, the form of the indication may be different, and since only a blinking indication is provided in this state, the value of t1 may be set to be larger as appropriate)

The key does not prompt the second state in the vehicle: when the vehicle is in the first state that the key is not in the vehicle, the driver does not find the prompt, presses the key starting switch again, and the operation is the power-on intention of the vehicle, detects that no intelligent effective key corresponding to the vehicle is in the vehicle, and enters the second state that the key is not in the vehicle. At this time, a blinking prompt of "please put the valid key in the car" with frequency f2 appears on the instrument screen, and a "dripping" sound prompt with frequency f2 is sent out at the same time, and the prompt time is t 2. (the prompting form can be different according to different manufacturers)

The key does not prompt the third state in the vehicle: at t4 after the vehicle enters the key and does not indicate the second state in the vehicle (to avoid that the second state is not indicated in the vehicle just after the key is exited, the driver presses the key start switch quickly, at which time the driver should be prompted again in the most obvious manner, so that the time t4> t2 is set, and each time the key exit does not indicate the third state in the vehicle, to avoid the driver continuing to press the key start switch, the key start switch state t4s needs to be detected, if the key start switch is pressed during the period and the key is not in the vehicle, the key does not indicate the third state in the vehicle, the driver is prompted again), the driver still does not find the prompt, presses the key start switch again, and the operation is the intention of electrifying the vehicle, and at the moment, the situation that no intelligent valid key corresponding to the vehicle exists in the vehicle is detected, and at the moment, the key is not in the vehicle, and the third state is prompted. At this time, it indicates that the driver does not notice the text prompt/sound prompt in the meter, and therefore, after entering the third state that the key is not in the vehicle, a flashing prompt of "please put the smart valid key into the vehicle" appears on the meter screen at a faster frequency f3(f3 is greater than f1/f2), and simultaneously, the continuous and uninterrupted "dropping" sound prompt is accompanied, and the prompt time is t 3. (the prompting form can be different according to different manufacturers)

3. Control process for prompting function that key is not in vehicle

In this patent, 3 kinds of keys total do not indicate the state in the car: the key is not in the vehicle to indicate a first state, the key is not in the vehicle to indicate a second state, and the key is not in the vehicle to indicate a third state.

The key does not prompt the first state in the vehicle and only prompts in a character, the key does not prompt the second state in the vehicle and also prompts in a buzzer with frequency except the character prompt, and the key does not prompt the third state in the vehicle and also prompts in the buzzer continuously except the character prompt. The key is not in the vehicle to prompt the first state, the key is not in the vehicle to prompt the second state, the key is not in the vehicle to prompt the third state is set according to the frequency and the times of pressing a key start switch by a driver, the prompting is more and more obvious, and the priorities of the three are sequentially increased (namely, if the conditions that the key is not in the vehicle to prompt the first state, the key is not in the vehicle to prompt the second state, and the key is not in the vehicle to prompt the third state are simultaneously met, the key is in the state with the highest priority-the key is not in the vehicle to prompt the third state, so that the driver can be more obviously prompted).

3.1 enter key not in the car to indicate the first state control flow

Referring to fig. 3, it is determined whether the one-key start switch is pressed in real time, if the one-key start switch is pressed and the operation intention is a vehicle power-on intention (i.e., if a key is in the vehicle, the vehicle can be powered on), an in-vehicle key detection command is sent, and the PEPS controller returns an intelligent key detection result. If the intelligent valid key is detected in the vehicle, the vehicle is normally powered on; if the intelligent valid key is not detected in the vehicle, the entering key does not prompt the first state in the vehicle, a flashing prompt of 'please put the intelligent valid key in the vehicle' with the frequency of f1 appears on the instrument screen, and the prompt time is t 1. After t1, or if the valid key in the vehicle is detected again and the smart valid key is detected in the vehicle, the exit key does not indicate the first state in the vehicle.

3.2 enter key not in the car to suggest the second state control flow

Referring to fig. 4, the first state is prompted when the key is not in the vehicle is detected in real time, whether the first state is prompted when the key is not in the vehicle enters the first state prompted when the key is not in the vehicle, and if the jump occurs, the detection process of the state of the one-key starting switch is started.

And in the one-key starting switch state detection process, judging whether the exit key does not prompt the first state in the vehicle in real time, and if the exit key does not prompt the first state in the vehicle, synchronously exiting the one-key starting switch state detection process.

In the one-key starting switch state detection process, whether a one-key starting switch is pressed down or not is judged in real time, if the one-key starting switch is pressed down and the operation intention is a vehicle power-on intention (namely, if a key is arranged in the vehicle, the vehicle can be powered on), an in-vehicle key detection command is sent out at the moment, the PEPS controller returns an intelligent key detection result, if an intelligent effective key is arranged in the vehicle, the vehicle is normally powered on, and a key quitting state does not exist in the vehicle, so that a first state is prompted; if the intelligent valid key is not detected in the vehicle, the entering key is not in the vehicle to prompt the second state, the exiting key is not in the vehicle to prompt the first state, a flickering prompt of 'please put the intelligent valid key into the vehicle' with the frequency of f2 appears on the instrument screen, and a 'dripping' sound prompt with the frequency of f2 is sent out at the same time, and the prompt time is t 2. After t2, or if the valid key in the vehicle is detected again and the smart valid key is detected in the vehicle, the exit key does not indicate the second state in the vehicle.

3.3 enter Key not in the third State control flow

Referring to fig. 5, the second state is prompted when the key is not in the vehicle is detected in real time, whether the second state is prompted when the key is not in the vehicle enters the second state prompted when the key is not in the vehicle, if the jump occurs, a one-key starting switch state detection process is started, and the timer 1 is started.

In the one-key-on switch state detection flow, if the one-key-on switch is not pressed for the period and the timer 1> -t 4, the one-key-on switch state detection flow is exited and the timer 1 is cleared by 0.

In the one-key starting switch state detection process, whether a one-key starting switch is pressed down or not is judged in real time, if the one-key starting switch is pressed down and the operation intention is a vehicle power-on intention (namely, if a key is arranged in the vehicle, the vehicle can be powered on), an in-vehicle key detection command is sent out at the moment, the PEPS controller returns an intelligent key detection result, if an intelligent effective key is detected in the vehicle, the timer 1 is clear 0, the vehicle is normally powered on, and if the key is not in the vehicle at the moment and a second state is prompted, the PEPS controller needs to quit the key and does not prompt the second state in the vehicle.

In the one-key starting switch state detection process, whether the one-key starting switch is pressed is judged in real time, if the one-key starting switch is pressed and the operation intention is a vehicle power-on intention (namely, if a key is in the vehicle, the vehicle can be powered on), an in-vehicle key detection command is sent at the moment, the PEPS controller returns an intelligent key detection result, if no intelligent valid key is detected in the vehicle, the timer 1 is cleared 0, if the key is not in the vehicle at the moment, a second state is required to be withdrawn, the key is not in the vehicle, and a third state is required to be entered, a flicker prompt of 'please put the intelligent valid key into the vehicle' with a faster frequency f3(f3 is larger than f1/f2) appears on an instrument screen, and meanwhile, a continuous 'dripping' sound prompt is accompanied, and the prompt time is t 3. After t3, or if the valid key in the vehicle is triggered again during the period and the valid key in the vehicle is detected, the exit key does not prompt the third state in the vehicle, and the one-key start switch state detection process is entered again, until the valid key in the vehicle is detected or the timer 1 is greater than or equal to t4 during the one-key start switch state detection process, the one-key start switch state detection process is exited.

Various parameters in the technical solution. Such as t1, t2, t3, t4, f1, f2 (different values can be set according to different manufacturers). These conditions may be varied to accomplish the object of the invention.
