Description

Technical Field

[0001] The present invention relates to the technical field of shift handles, in particular to an anti-slip vehicle shift handle and its working method. Background Art

[0002] The vehicle shift handle is a core component in the vehicle control system. It is a key medium for the driver to interact with the vehicle's power transmission system, mainly used to achieve gear shifting such as forward, reverse, neutral, and parking, thereby controlling the driving state and power output of the vehicle. Structurally, it usually consists of a handle body, a connecting shaft, a transmission mechanism, an electronic control unit, etc. The shift handles of some high-end models also integrate intelligent components such as sensors and displays. Functionally, early shift handles only had basic manual shifting functions, while modern shift handles continuously integrate innovative technologies, giving rise to diverse interaction methods and practical functions: such as achieving multi-mode tactile feedback through linear vibration motors, piezoelectric ceramic elements, etc., enabling the driver to obtain clear and intuitive tactile cues when shifting gears; realizing gesture sensing operations with sensors such as infrared and millimeter-wave radar, supporting contactless shifting and multi-system linkage control of the vehicle; adopting a composite structure of carbon fiber reinforced composite material and high-strength aluminum alloy, taking into account lightweight and high strength, and improving vehicle performance and safety; designing pluggable interfaces and modular internal structures to facilitate users to replace and upgrade function modules by themselves. The vehicle shift handle is developing towards the direction of intelligence, humanization, and multi-functionality, not only significantly improving the convenience, comfort, and safety of driving operations, but also greatly enhancing the technological sense and market competitiveness of the vehicle.

[0003] Chinese Patent Publication No. CN210830413U discloses a shift handle, which includes a housing provided with a first opening, and a key is arranged in the first opening; a control board assembly and a rotary trigger are arranged in the housing; a switch button is arranged on the control board assembly; the rotary trigger is rotatably connected to the housing, and it has a trigger end and an actuating end, and the trigger end and the actuating end respectively abut against the key and the switch button; a downwardly inclined diversion member is arranged on the rotary trigger, and the diversion member is located above a part of the control board assembly. The shift handle of the present invention realizes that the water entering the housing through the assembly gap between the key and the housing can flow along the diversion member and drain out of the control board assembly by arranging the diversion member on the rotary trigger. Thus, without configuring additional shielding components inside the shift handle, waterproof protection for the PCB board and electronic components can be achieved. While meeting the multi-functional additions such as the lighting of the shift handle and the triggering of the parking gear signal, the internal structural complexity of the shift handle is not increased, and the cost is relatively low.

[0004] The existing technical solutions mentioned above have the following drawbacks: the existing vehicle gear shift levers lack a feedback mechanism. After shifting gears, novice drivers cannot intuitively perceive whether the shift was successful or the gear position status. They need to confirm through the instrument panel display, which increases the complexity of operation and affects driving safety. Therefore, we propose an anti-slip vehicle gear shift lever and its working method to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide an anti-slip vehicle gear shift lever and its working method, in order to solve the problem mentioned in the background art that existing vehicle gear shift levers lack a feedback mechanism. Novice drivers cannot intuitively perceive whether the gear shift was successful or the gear switching status after shifting gears, and need to confirm it through the instrument panel display, which increases the complexity of operation and also affects driving safety.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an anti-slip vehicle gear shift lever, comprising a gear shift lever, a central control system, a cloud server, a gear shift lever system, and a vibration motor mount. A prompting top block housing is fixedly installed inside the upper end of the gear shift lever. A prompting top block is slidably installed inside the prompting top block housing. An electric telescopic rod is installed between the lower end of the prompting top block and the inner wall of the prompting top block housing. A control unit is installed inside the gear shift lever system. A vibration motor mount is installed above the gear shift lever, and a vibration motor is installed inside the vibration motor mount. The gear shift lever system includes a vehicle speed sensor and a throttle position sensor. The vehicle speed sensor detects the vehicle speed and transmits an electrical signal to the control unit. The throttle position sensor accurately senses the current gear position of the gear shift lever and converts this position information into an electrical signal, which is transmitted to the control unit. The control unit controls the extension and retraction of the electric telescopic rod and the vibration of the vibration motor to indicate the current gear position to the driver.

[0007] Preferably, a gear shift slot plate is installed above the gear shift mechanism, and a gear shift handle rod is installed below the gear shift handle.

[0008] Preferably, a plurality of first anti-slip strips are symmetrically installed at equal intervals on both sides of the gear shift lever, and a second anti-slip strip is symmetrically installed at equal intervals on both sides of the front end of the gear shift lever.

[0009] Preferably, a heart rate sensor is installed at the center of the front side above the gear shift lever, and two skin conductance sensors are installed on one side of the indicator block.

[0010] Preferably, a temperature-measuring infrared sensor housing is installed at the middle position of the front side of the lower end of the gear shift lever, and a temperature-measuring infrared sensor is installed inside the temperature-measuring infrared sensor housing.

[0011] Preferably, a fixed base is fixedly provided inside the lower end of the gear shift handle, and a vibration motor output end slot is opened at the middle position of the lower end of the fixed base, and the output end of the vibration motor is in contact with the inner wall of the vibration motor output end slot.

[0012] Preferably, a shift lever connecting block is provided at the upper end of the shift lever handle, the shift lever connecting block is located inside the vibrating motor base and fixedly connected, a shift lever groove is provided at the middle position of the lower end of the vibrating motor base, the diameter of the shift lever groove is smaller than the diameter of the shift lever connecting block, and a vibrating motor is fixedly installed above the shift lever connecting block.

[0013] Preferably, the heart rate sensor, the infrared temperature sensor, the skin conductance sensor, the vehicle speed sensor, and the throttle position sensor are electrically connected to the control unit.

[0014] Preferably, the control unit is electrically connected to the electric telescopic rod and the vibration motor respectively, the control unit is electrically connected to the central control system, the central control system is electrically connected to the central control screen, and the control unit is electrically connected to the cloud server.

[0015] A method for operating an anti-slip vehicle gear shift lever includes the following steps:

[0016] Step 1: During driving, the vehicle speed sensor detects the vehicle speed and transmits the electrical signal to the control unit. The throttle position sensor accurately senses the current gear position of the gear shift lever and converts this position information into an electrical signal, which is then transmitted to the control unit. The control unit controls the extension and retraction of the electric telescopic rod and the vibration of the vibration motor to indicate the current gear position to the driver. At the same time, the control unit sends a signal to the central control system, which controls the central control screen to display the current gear position.

[0017] Step Two: Insert your finger into the heart rate sensor. The heart rate sensor monitors the heart rate in real time and sends the data to the control unit. The skin of your palm is in contact with two skin conductance sensors. These sensors detect real-time changes in the skin's surface conductivity and send the data to the control unit. Changes in conductivity indirectly reflect the excitation level of the human sympathetic nervous system. An infrared temperature sensor emits infrared rays to detect the temperature at the driver's wrist and sends the data to the control unit. The control unit analyzes and processes the data to determine if the driver is fatigued or in a state of stress. If an abnormality is detected, the control unit controls the electric telescopic rod to slowly extend and the vibration motor to vibrate, prompting the driver to adjust their state. The central control system automatically adjusts the in-car air conditioning temperature and plays refreshing or soothing music to alleviate the driver's discomfort.

[0018] Step 3: The physiological data collected by the heart rate sensor, skin conductance sensor, and infrared thermometer is collected and analyzed by the control unit and uploaded to the cloud server to analyze the recent fluctuations in physiological data. When abnormal fluctuations or potential health risks are detected, such as excessively fast heart rate for several consecutive days which may indicate heart problems, the central control system will control the central control screen to prompt the driver for abnormal body data. In the event of an emergency health condition, the central control system will automatically contact the nearest hospital and provide the driver's health data.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. This invention uses a vehicle speed sensor and a throttle position sensor to collect real-time information on vehicle speed and gear shift lever position. The control unit then controls the electric telescopic rod and vibration motor to work, using extension and vibration to indicate the current gear to the driver. Simultaneously, the information is displayed on the central control screen, preventing the driver from being distracted by looking down at the gear position. This allows for quick and accurate gear confirmation even in complex road conditions, effectively reducing the risk of traffic accidents caused by misjudging the gear position.

[0021] 2. This invention utilizes a heart rate sensor, a skin conductance sensor, and a temperature-measuring infrared sensor to work in tandem, monitoring the driver's heart rate, skin conductance, and body temperature in real time. The control unit analyzes the data and, upon detecting driver fatigue or stress, issues a warning via an electric telescopic rod and a vibration motor. Simultaneously, the central control system automatically adjusts the vehicle's air conditioning temperature and plays music to help alleviate driver discomfort and reduce driving errors caused by poor physical condition, making the driving process safer and more comfortable. The physiological data collected by various sensors is aggregated and analyzed by the control unit and uploaded to a cloud server. In-depth analysis of recent data fluctuations allows for the early prediction of potential health risks. When an abnormality is detected, the central control screen promptly reminds the driver to pay attention to their physical condition. In emergency health situations, the system automatically contacts nearby hospitals and provides health data, safeguarding the driver's health and demonstrating the vehicle's human-centered design, thus enhancing user satisfaction with the product.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] Please see Figure 1-5 One embodiment of the present invention provides an anti-slip vehicle gear shift lever, comprising a gear shift lever 4, a central control system 19, a cloud server 20, a gear shift lever system 24, and a vibration motor mount 25. A prompting top block housing 12 is fixedly installed inside the upper end of the gear shift lever 4. A prompting top block 10 is slidably installed inside the prompting top block housing 12. An electric telescopic rod 13 is installed between the lower end of the prompting top block 10 and the inner wall of the prompting top block housing 12. A control unit 18 is installed inside the gear shift lever system 24. A vibration motor mount 25 is installed above the gear shift lever 4, and a vibration motor 16 is installed inside the vibration motor mount 25. The gear shift lever system 24 includes a vehicle speed sensor 22 and a throttle position sensor 23. The vehicle speed sensor 22 detects the vehicle speed and transmits an electrical signal to the control unit 18. The throttle position sensor 23 accurately senses the current gear position of the gear shift lever 4 and converts this position information into an electrical signal, which is transmitted to the control unit 18. The control unit 18 controls the extension and retraction of the electric telescopic rod 13 and the vibration of the vibration motor 16 to indicate the current gear position to the driver.

[0030] The vehicle speed sensor 22 and throttle position sensor 23 collect information on the vehicle speed and gear position of the gear shift lever in real time. The control unit 18 drives the electric telescopic rod 13 and the vibration motor 16 to transmit the current gear position to the driver through extension and vibration. This prevents the driver from being distracted by looking away from the road to check the gear position, improves driving focus and safety, and can effectively reduce the risk of accidents caused by misjudging the gear position, especially in complex road conditions.

[0031] Please see Figure 1-3A gear shift slot plate 2 is installed above the gear shift mechanism 1, and a gear shift lever 3 is installed below the gear shift lever 4. Multiple first anti-slip strips 8 are symmetrically installed at equal intervals on both sides of the gear shift lever 4, and second anti-slip strips 9 are symmetrically installed at equal intervals on both sides of the front end of the gear shift lever 4.

[0032] The first anti-slip strip 8 and the second anti-slip strip 9 set on both sides and the front end of the gear shift lever 4 increase the friction between the lever surface and the hand. During driving, whether it is normal operation or emergency gear shifting, it can effectively prevent the hand from slipping, ensure the driver's stable grip on the gear shift lever 4, make the gear shifting operation more precise and reliable, and provide a guarantee for safe driving.

[0033] Please see Figure 1-4 A heart rate sensor 5 is installed at the center of the front side above the gear shift lever 4, and two skin conductance sensors 11 are installed on one side of the indicator block 10. A temperature-measuring infrared sensor housing 6 is installed at the center of the front side of the lower end of the gear shift lever 4, and a temperature-measuring infrared sensor 7 is installed inside the temperature-measuring infrared sensor housing 6.

[0034] The heart rate sensor 5, skin conductance sensor 11, and temperature infrared sensor 7 work together to monitor the driver's heart rate, skin conductance, body temperature, and other physiological indicators in real time. The control unit 18 analyzes and processes the data. Once it detects that the driver is in a poor physical state such as fatigue or tension, it will issue a timely reminder and link the central control system 19 to adjust the in-vehicle environment. It can also predict potential health risks through the cloud server 20, thus comprehensively protecting the driver's health and driving safety.

[0035] Please see Figure 4 A fixed base 14 is fixedly installed inside the lower end of the gear shift lever 4. A vibration motor output end slot 15 is opened at the middle position of the lower end of the fixed base 14. The output end of the vibration motor 16 is in contact with the inner wall of the vibration motor output end slot 15. A gear shift lever connecting block 17 is provided at the upper end of the gear shift lever 3. The gear shift lever connecting block 17 is located inside the vibration motor base 25 and is fixedly connected. A gear shift lever slot is opened at the middle position of the lower end of the vibration motor base 25. The diameter of the gear shift lever slot is smaller than the diameter of the gear shift lever connecting block 17. The vibration motor 16 is fixedly installed above the gear shift lever connecting block 17.

[0036] The fixed base 14, the vibration motor output end slot 15, and the shift handle rod connecting block 17 constitute a stable installation structure, ensuring that the vibration motor 16 is stable and without displacement during operation, so that the vibration indication function can operate continuously and reliably. At the same time, it enhances the overall strength and durability of the shift handle 4, reducing the problem of functional failure caused by loose or damaged parts.

[0037] Please see Figure 1-5The heart rate sensor 5, the infrared temperature sensor 7, the skin conductance sensor 11, the vehicle speed sensor 22, and the throttle position sensor 23 are electrically connected to the control unit 18. The control unit 18 is electrically connected to the electric telescopic rod 13 and the vibration motor 16, the central control system 19, the central control screen 21, and the cloud server 20.

[0038] The system enables efficient data transmission and sharing, allowing the gear shift lever system 24 to not only provide basic gear shift prompts, but also perform various functions such as health monitoring, in-vehicle environment adjustment, and cloud data analysis. The intelligent collaboration between the various systems provides drivers with a convenient, intelligent, and safe driving experience, thereby improving the overall intelligence level of the vehicle.

[0039] A method for operating an anti-slip vehicle gear shift lever includes the following steps:

[0040] Step 1: During driving, the vehicle speed sensor 22 detects the vehicle speed and transmits an electrical signal to the control unit 18. The throttle position sensor 23 accurately senses the current gear position of the gear shift lever 4 and converts this position information into an electrical signal, which is then transmitted to the control unit 18. The control unit 18 controls the extension and retraction of the electric telescopic rod 13 and the vibration of the vibration motor 16 to indicate the current gear position to the driver. At the same time, the control unit 18 sends a signal to the central control system 19, which controls the central control screen 21 to display the current gear position.

[0041] Step Two: Insert a finger into heart rate sensor 5. Heart rate sensor 5 monitors heart rate in real time and sends the data to control unit 18. The palm skin is in contact with two skin conductance sensors 11. Skin conductance sensors 11 detect real-time changes in skin surface conductivity and send the data to control unit 18. Changes in conductivity indirectly reflect the excitation level of the human sympathetic nervous system. Infrared sensor 7 emits infrared rays to detect the temperature at the driver's wrist and sends the data to control unit 18. Control unit 18 analyzes and processes the data to determine whether the driver is in a state of fatigue or tension. If an abnormality is detected, control unit 18 controls the electric telescopic rod 13 to slowly vibrate and the vibration motor 16 to prompt the driver to adjust their state. Central control system 19 automatically adjusts the in-vehicle air conditioning temperature and plays refreshing or soothing music to alleviate the driver's poor state.

[0042] The raw data collected by the heart rate sensor (5), the infrared thermometer (7), and the skin conductance sensor (11) are filtered to remove noise interference. For example, the moving average filtering method is used to calculate the average of multiple sets of continuously collected data to make the data smoother and more stable. Through a large number of experiments and studies, normal range thresholds for heart rate, body temperature, and skin conductance are set respectively. For example, under normal driving conditions, the heart rate is generally 60-100 beats / minute, the body temperature is 36℃-37.2℃, and the skin conductance is in a relatively stable range.

[0043] Real-time monitoring of sensor data indicates that the driver may be under stress if the heart rate is consistently above the upper limit of the normal range, body temperature rises or falls abnormally, and skin conductivity increases significantly. If the heart rate is abnormally slow or fluctuates irregularly, body temperature drops, and skin conductivity changes little but remains at a low level, the driver may be fatigued.

[0044] Data collected from the heart rate sensor (5), temperature infrared sensor (7), and skin conductance sensor (11) under various driving scenarios, when the driver is in a normal, fatigued, or tense state, were manually labeled to clarify the corresponding state category of the data.

[0045] Extract valuable features from the raw data, such as the rate of change in heart rate, the fluctuation range of body temperature, and the trend of skin conductivity. Combine these features into a feature vector, which serves as the input to a machine learning model. Choose an appropriate machine learning model, such as Support Vector Machine (SVM), Random Forest, or Neural Network. Train the model using a labeled dataset, adjusting the model parameters to achieve good classification accuracy on both the training and validation sets.

[0046] After feature extraction, the real-time sensor data is input into the trained model, which outputs a prediction of the driver's state, thereby determining whether the driver is in a state of fatigue or stress.

[0047] Using fuzzy logic algorithm

[0048] Fuzzy rules are formulated based on driving experience and physiological knowledge. For example, if the heart rate is "high," body temperature is "high," and skin conductivity is "high," then the driver is "nervous"; if the heart rate is "low and fluctuates irregularly," body temperature is "low," and skin conductivity is "low," then the driver is "fatigued." The membership degrees of the real-time sensor data in each fuzzy set are calculated using membership functions. Then, reasoning is performed based on the fuzzy rules, and finally, through defuzzification, the final judgment of whether the driver is fatigued or nervous is obtained.

[0049] Step 3: The physiological data collected by the heart rate sensor 5, skin conductance sensor 11, and infrared temperature sensor 7 are collected and analyzed by the control unit 18 and uploaded to the cloud server 20 to analyze the recent fluctuations in physiological data. When abnormal fluctuations or potential health risks are detected, such as excessively fast heart rate for several consecutive days which may indicate heart problems, the central control system 19 controls the central control screen 21 to prompt the driver about abnormal body data. In the event of an emergency health condition, the central control system 19 automatically contacts the nearest hospital and provides the driver's health data.

[0050] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
