Abstract

The application discloses a vehicle seat vibrator control method and device, and relates to the technical field of fatigue driving. In the process of driving, if it is detected that the driver is in a fatigue driving state, the pressure values borne by each position on the driver's seat are obtained multiple times, the average values of the multiple pressure values corresponding to each position on the driver's seat are calculated, and the seat vibrator at the position corresponding to the maximum average value is controlled to vibrate. The position corresponding to the maximum average value of the pressure values can be considered as the place on the driver's seat that is most closely contacted with the driver's body. Controlling the seat vibrator at the position with the maximum average value of the pressure values to vibrate can maximize the stimulating effect on the driver, can guarantee the reminding effect, can wake up the driver as much as possible, and can avoid all the vibrators under the driver's seat from vibrating. In the process of guaranteeing the fatigue driving reminding effect, the wasted electric energy of the seat vibrator is greatly reduced.

Description

Technical Field

[0001] This invention relates to the field of fatigue driving technology, and more particularly to a method and device for controlling vehicle seat vibrators. Background Technology

[0002] Because drowsy driving easily leads to accidents, some vehicles install vibrators under the seat cushions. These vibrators activate when driver fatigue is detected, aiming to wake the driver. However, currently, vibrators are widely distributed under the seat cushions, and all vibrate simultaneously. While this generally provides a good wake-up effect, some vibrators contribute virtually nothing to waking the driver, and the simultaneous vibration of all vibrators wastes a significant amount of electrical energy. This energy waste is particularly problematic for electric vehicles, reducing their driving range. Therefore, reducing the energy wasted by vehicle seat vibrators is a key issue that needs to be addressed. Summary of the Invention

[0019] On the other hand, embodiments of the present invention also provide the following technical solutions:

[0028] The control module is also used for:

[0029] If the difference between the first heart rate value and the second heart rate value is less than a preset heart rate value, then the vehicle seat vibrator is subject to preset control.

[0036] To more clearly illustrate the technical solutions in the embodiments of the present invention, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the accompanying drawings described below are some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0037] Figure 1 This is a flowchart of the vehicle seat vibrator control method in an embodiment of the present invention;

[0038] Figure 2 This is a schematic diagram of a vehicle seat vibrator control device in an embodiment of the present invention. Detailed Implementation

[0039] The embodiments of the present invention solve the technical problem of wasting electrical energy when a vehicle seat vibrator vibrates, as described in the prior art, through a vehicle seat vibrator control method and device.

[0040] To better understand the technical solution of the present invention, the technical solution of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] In this embodiment, it is assumed that each seat cushion and backrest of the vehicle is equipped with a vibrator and a pressure sensor. The pressure sensor can detect the pressure value at each position on the seat.

[0042] like Figure 1 As shown, the vehicle seat vibrator control method of this embodiment includes:

[0043] Step S1: If the driver is detected to be in a state of fatigue while the vehicle is in motion, the pressure values ​​of each position on the driver's seat are obtained multiple times.

[0044] Step S2: Calculate the average of multiple pressure values ​​corresponding to each position on the driver's seat;

[0045] Step S3: Control the vibration of the seat vibrator at the position corresponding to the position with the largest average value.

[0046] It is understandable that a driver's driving posture remains fixed for most of the driving process. This results in minimal variation in the pressure values ​​across different positions on the driver's seat, and a specific position on the driver's seat will inevitably experience the greatest pressure – the position in closest contact with the driver's body (such as the buttocks or back). In step S1, the pressure values ​​at each position on the seat will be collected multiple times during periods of driver fatigue.

[0047] Considering that determining the final pressure at each position on the seat might result in inaccurate pressure values ​​if only one or two pressure values ​​are used as the result, in step S2, the average of multiple pressure values ​​corresponding to each position is taken as the final pressure value for that position.

[0048] In this embodiment, it can be understood that the location corresponding to the highest average pressure value can be considered as the point on the driver's seat with the closest contact with the driver's body. Controlling the vibration of the seat vibrator at the point of highest average pressure value has the greatest stimulating effect on the driver, ensuring the reminder effect and waking the driver up as much as possible. Furthermore, it avoids all vibrators under the driver's seat vibrating simultaneously, greatly reducing the wasted energy of the seat vibrators while ensuring the fatigue driving reminder effect.

[0049] In this embodiment, considering that controlling only the seat vibrator at the position with the highest average pressure might still result in insufficient alertness, it is understood that the more seat vibrators vibrate, the greater the alertness for driver fatigue. However, controlling the vibrators in areas of the seat with loose contact with the driver also to vibrate would neither improve the alertness nor significantly increase energy waste. This embodiment can selectively control the vibration of seat vibrators at all positions on the seat where the contact with the driver's body is above a certain level, thus improving the alertness for driver fatigue without causing significant energy waste. Therefore, after step S2, the vehicle seat vibrator control method of this embodiment may further include:

[0050] The vibration of the seat vibrator is controlled at all positions corresponding to the average values ​​within the preset pressure range, where the maximum value of the preset pressure range is the maximum value among the average values.

[0051] In this embodiment, if the average pressure at a certain location is higher than the minimum value of a preset pressure range, it indicates that the contact between that location and the driver's body is relatively close. Controlling the vibration of the seat vibrator at that location serves as a reminder to the driver. This embodiment is equivalent to not controlling the vibration of the seat vibrator at locations where the average pressure is lower than the minimum value of the preset pressure range, thus avoiding significant energy waste. The minimum value of the preset pressure range can be 2 / 3 of the maximum value. Practice shows that at locations where the average pressure is lower than 2 / 3 of the maximum value, the contact between the seat vibrator and the driver's body is relatively small, and the vibration of the seat vibrator at this location has virtually no reminder effect; at locations where the average pressure is higher than 2 / 3 of the maximum value, the contact between the seat vibrator and the driver's body is relatively large, and the vibration of the seat vibrator at this location serves as a reminder.

[0052] Considering that excessive vibration intensity of the seat vibrator might cause an overreaction by the driver, potentially leading to a safety accident, this embodiment selects to control the vibration intensity of the seat vibrator to a preset intensity. The preset intensity is the maximum intensity to avoid an overreaction by the driver, and it is also lower than the maximum vibration intensity the seat vibrator can provide. However, if the driver has virtually no reaction when the seat vibrator vibrates at the preset intensity, the importance of preventing accidents caused by driver fatigue is necessarily higher than the importance of preventing an overreaction by the driver. Therefore, the vibration intensity of the seat vibrator should be allowed to exceed the preset intensity. Thus, before step S3, the vehicle seat vibrator control method of this embodiment may further include: acquiring the driver's first heart rate value; after step S3, the vehicle seat vibrator control method may further include: acquiring the driver's second heart rate value; if the difference between the first heart rate value and the second heart rate value is less than the preset heart rate value, then the vibration intensity of the seat vibrator is increased.

[0053] The driver's heart rate can be detected using existing heart rate monitoring devices such as wristbands, watches, or steering wheels. The first heart rate value is the driver's heart rate before the seat vibrator vibrates (when the driver is fatigued), and the second heart rate value is the driver's heart rate after the seat vibrator vibrates. It is understood that the human heart rate increases after stimulation, especially when stimulated in a fatigued state. In this embodiment, if the seat vibrator stimulates the driver at a preset intensity, the difference between the first and second heart rate values ​​should be significant, such as greater than the preset heart rate value. However, if the difference between the first and second heart rate values ​​is less than the preset heart rate value, it means that the seat vibrator at the preset intensity has no effect on the driver, and the vibration intensity of the seat vibrator needs to be increased to wake the driver as much as possible.

[0054] In addition, this embodiment can also select to keep the vibration intensity of the seat vibrator at the maximum vibration intensity that the seat vibrator can provide, without considering the driver's overreaction. If this still has no effect on the driver, since the vibration intensity of the seat vibrator has no room for further increase, it is necessary to consider reminding or waking up other passengers so that they can wake up the driver. Thus, before step S3, the vehicle seat vibrator control method of this embodiment can also include: obtaining the driver's first heart rate value; after step S3, the vehicle seat vibrator control method can also include: obtaining the driver's second heart rate value; if the difference between the first heart rate value and the second heart rate value is less than a preset heart rate value, then detecting whether there are other passengers in the vehicle; if there are other passengers in the vehicle, then controlling the vibration of the seat vibrator under the other passengers. This allows the vibration of the seat vibrator under other passengers to be controlled when the vibration of the driver's seat vibrator has no effect on the driver, thereby reminding other passengers that the driver is in a state of fatigue driving and waking up other passengers, which is beneficial for timely waking up the driver.

[0055] like Figure 2 As shown, this embodiment also provides a vehicle seat vibrator control device, including:

[0056] The acquisition module is used to acquire the pressure values ​​of various positions on the driver's seat multiple times during vehicle operation if the driver is detected to be in a state of fatigue driving.

[0058] The control module is used to control the vibration of the seat vibrator at the position corresponding to the position with the largest average value.

[0059] Preferably, the control module is also used for:

[0060] The vibration of the seat vibrator is controlled at all positions corresponding to the average values ​​within the preset pressure range, where the maximum value of the preset pressure range is the maximum value among the average values.

[0061] The acquisition module is further configured to: acquire the driver's first heart rate value before the seat vibrator at the position corresponding to the maximum of the average values ​​controlled by the control module vibrates; and acquire the driver's second heart rate value after the seat vibrator at the position corresponding to the maximum of the average values ​​controlled by the control module vibrates.

[0062] The control module is also used to: if the difference between the first heart rate value and the second heart rate value is less than the preset heart rate value, then to perform preset control on the vehicle seat vibrator.
