[0041] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0042] like Figure 1 As shown, the system for automatically adjusting steering wheel damping provided by this embodiment includes:

[0043] Steering wheel grip force detection module 1, used to detect the pressure of the driver's hand on the steering wheel;

[0044] An automotive electronic control unit (ECU) 3 is used to analyze the detection result of the steering wheel grip force detection module 1 to obtain the driver's operation intention, and obtain a steering wheel damping adjustment strategy according to the driver's operation intention;

[0045] The steering system 4 is used to control the steering of the steering wheel according to the steering wheel damping adjustment strategy and adjust the damping of the steering wheel.

[0046] Wherein, the steering wheel grip force detection module 1 comprises:

[0047] A plurality of flexible pressure sensors are arranged on both sides of the hand gripping position of the steering wheel to collect the pressure signal of the driver's hand gripping the steering wheel;

[0048] A plurality of resistance measuring units are built into each of the flexible pressure sensors and are used to convert the pressure signals collected by each of the flexible pressure sensors into corresponding resistance change signals.

[0049] Specifically, each of the flexible pressure sensors is fixed to the inner surface of both sides of the steering wheel by bonding. Flexible pressure sensors are usually manufactured in a thin and soft form and can be easily attached to the surface of the steering wheel. Flexible pressure sensors can increase safety and the ability to withstand deformation, and are suitable for curved surfaces. Data can be stored and transmitted to the automotive electronic controller unit 3 or the signal processing circuit module 2 (described later) via Bluetooth when necessary for processing and analysis. By installing multiple flexible pressure sensors at different positions on the steering wheel, the position of the driver's hand and the different pressures applied to the steering wheel can be detected.

[0050] The flexible pressure sensor on the surface of the steering wheel usually contains conductive materials, such as conductive polymers or conductive nanomaterials. When the driver applies pressure, the resistance of these conductive materials changes. The flexible pressure sensor has a circuit inside that can measure the change in resistance. When pressure is applied to the surface of the flexible pressure sensor, the contact area and distance between the conductive materials will change, resulting in a change in resistance, which can be measured by the circuit.

[0051] Furthermore, the system for automatically adjusting the steering wheel damping also includes a signal processing circuit module 2, which is respectively connected to the steering wheel grip detection module 1 and the automotive electronic controller unit 3, and is used to convert the resistance change signal output by each resistance measurement unit into a digital or analog signal related to the pressure intensity, and send the processing result to the automotive electronic controller unit 3. The signal processing circuit module 2 is arranged inside the automotive electronic controller unit 3. The resistance change signal output by the sensor passes through the signal processing circuit module 2 to convert it into a digital or analog signal related to the pressure intensity. The resistance change signal output by the flexible pressure sensor can be processed by the signal processing circuit module 2 to convert the original resistance change signal generated by the flexible pressure sensor into a more meaningful and usable form such as an analog voltage or a digital signal.

[0052] Specifically, the signal processing circuit module 2 includes:

[0053] A signal amplifying unit, used for amplifying the resistance change signal corresponding to each of the flexible pressure sensors;

[0054] Filtering unit: used for filtering the resistance change signal processed by the signal amplifying unit;

[0055] Analog-to-digital conversion unit: used to convert the analog voltage signal of the resistance change signal processed by the filtering unit into a digital voltage signal;

[0056] Calibration and correction unit: used to calibrate and correct the digital voltage signal processed by the analog-to-digital conversion unit.

[0057] The resistance change signal output by the flexible pressure sensor may be relatively small, so it may be necessary to amplify the signal through an amplifier circuit and filter it through a filter unit to increase the signal-to-noise ratio. The analog-to-digital conversion unit converts the analog voltage signal into digital form through an analog-to-digital converter analog signal. Since the performance of the flexible pressure sensor may be affected by environmental conditions, manufacturing changes and other factors, calibration and correction through the calibration and correction unit can ensure that the output data is accurate and reliable.

[0058] Furthermore, the system for automatically adjusting the steering wheel damping also includes: a cloud data storage and analysis module 5, which is connected to the signal processing circuit module 2, and is used to analyze the detection results of the steering wheel grip detection module 1, obtain the driver's gripping method of the steering wheel in different situations, and store the detection results and analysis results. Cloud service is a platform for storing, managing and processing data from vehicles. The processed signal is transmitted to the cloud data storage and analysis module 5 via a cloud connection. The data analysis module located in the cloud service is responsible for analyzing the pressure data of holding the steering wheel, and can obtain the driver's gripping method of the steering wheel in different situations. This helps to identify the driver's habits and behavior patterns and provides a basis for improving the driving experience.

[0059] Furthermore, the automotive electronic controller unit 3 is specifically used for:

[0060] According to the detection result of the steering wheel grip force detection module 1, the position of each finger on both sides of the steering wheel and the pressure distribution corresponding to each finger are obtained;

[0061] The driver's operating intention is obtained according to the positions of the fingers on both sides of the steering wheel and the pressure distribution corresponding to each finger;

[0062] Obtaining a steering wheel damping adjustment strategy according to the driver's operating intention;

[0063] According to the steering wheel damping adjustment strategy, a steering wheel damping adjustment instruction is output to the steering system 4 .

[0064] The step of obtaining the driver's operation intention according to the positions of the fingers on both sides of the steering wheel and the pressure distribution corresponding to the fingers specifically includes:

[0065] If the driver increases the grip force while turning the steering wheel, the driver's operating intention is a change in the current road conditions.

[0066] Furthermore, the steering wheel damping adjustment strategy includes: if the current road condition changes, the steering wheel damping is reduced; and the steering wheel damping size is adaptively adjusted according to the driver's grip strength.

[0067] Furthermore, the steering system 4 is specifically used to receive the steering wheel damping adjustment instruction, control the steering of the steering wheel according to the steering wheel damping adjustment instruction, and adjust the damping size of the steering wheel. The steering wheel receives the steering wheel damping adjustment instruction output by the automobile electronic controller unit 3 and adjusts the damping size. Specifically, the automobile electronic controller unit 3 adjusts the steering wheel damping through the software and control algorithm in the electronic power steering system. The control algorithm in the automobile electronic controller unit 3 calculates the power assistance to be applied and the degree of damping adjustment in real time based on the received sensor data. The damping force of the steering wheel is adjusted through the motor in the electronic power steering system. The motor can apply additional power assistance to the steering system and simulate different damping feelings at the same time.

[0068] The data processed by the automotive electronic controller unit 3 or the signal processing circuit module 2 can be integrated with the vehicle's steering system to achieve the purpose of controlling the steering wheel. When the driver turns the steering wheel and increases the grip, it means that the current road conditions have changed, and it is necessary to output a command to reduce the steering wheel damping, so that the steering wheel damping can be reduced to facilitate the driver to easily turn the steering wheel; at the same time, the steering wheel damping is adaptively adjusted according to the driver's grip strength, and the steering wheel damping value is not always the same.

[0069] The system for automatically adjusting the steering wheel damping provided by the embodiment of the present invention receives the pressure generated by the driver's hands holding the steering wheel through a steering wheel grip force detection module, and determines the force applied to turn the steering wheel in the current driving scenario by recording and analyzing the pressure changes generated during the driving process; adjusts the steering wheel damping size according to the force applied to turn the steering wheel, helping the user to turn the steering wheel more easily; and can adaptively adjust the steering wheel damping size according to the strength with which each driver currently holds the steering wheel, helping the driver to drive the car more easily and safely.

[0070] like Figure 2 As shown, the method for automatically adjusting the steering wheel damping provided by this embodiment includes the following steps in actual implementation:

[0071] Step S1, detecting the pressure of the driver's hands on the steering wheel.

[0072] In one implementation of the method for automatically adjusting steering wheel damping of the present invention, step S1 may specifically include:

[0073] Step S11: collecting pressure signals of the driver's hands gripping the steering wheel through a plurality of flexible pressure sensors disposed on both sides of the hand gripping position of the steering wheel.

[0074] Wherein, each of the flexible pressure sensors is fixed to the inner surface of both sides of the steering wheel by bonding. The flexible pressure sensor is usually manufactured in a thin and soft form and can be easily attached to the surface of the steering wheel.

[0075] Step S12: converting the pressure signal collected by each of the flexible pressure sensors into a corresponding resistance change signal through a plurality of resistance measurement units built into each of the flexible pressure sensors.

[0076] The flexible pressure sensor on the surface of the steering wheel usually contains conductive materials, such as conductive polymers or conductive nanomaterials. When the driver applies pressure, the resistance of these conductive materials changes. The flexible pressure sensor has a circuit inside that can measure the change in resistance. When pressure is applied to the surface of the flexible pressure sensor, the contact area and distance between the conductive materials will change, resulting in a change in resistance, which can be measured by the circuit.

[0077] Step S2: analyzing the detection result of the pressure of the driver's hand on the steering wheel to obtain the driver's operation intention, and obtaining the steering wheel damping adjustment strategy according to the driver's operation intention.

[0078] Specifically, the automobile electronic controller unit analyzes the detection result of the pressure of the driver's hand on the steering wheel to obtain the driver's operation intention, and obtains the steering wheel damping adjustment strategy according to the driver's operation intention. In one embodiment of the method for automatically adjusting the steering wheel damping of the present invention, the step S2 may specifically include:

[0079] Step S21, obtaining the position of each finger on both sides of the steering wheel and the pressure distribution corresponding to each finger according to the detection result of the steering wheel grip force detection module 1.

[0080] Step S22: Obtain the driver's operation intention according to the positions of the fingers on both sides of the steering wheel and the pressure distribution corresponding to the fingers.

[0081] Specifically, if the driver increases the grip force while turning the steering wheel, the driver's operating intention is a change in the current road condition.

[0082] Step S23: Obtain a steering wheel damping adjustment strategy according to the driver's operating intention.

[0083] The steering wheel damping adjustment strategy includes: if the current road condition changes, the steering wheel damping is reduced; and the steering wheel damping size is adaptively adjusted according to the driver's grip strength.

[0084] Step S24: output a steering wheel damping adjustment instruction to the steering system 4 according to the steering wheel damping adjustment strategy.

[0085] Step S3: controlling the steering of the steering wheel according to the steering wheel damping adjustment strategy, and adjusting the damping of the steering wheel.

[0086] Among them, the steering wheel steering is controlled by the steering system according to the steering wheel damping adjustment strategy, and the damping of the steering wheel is adjusted. Specifically, the steering wheel damping adjustment instruction is received, the steering wheel steering is controlled according to the steering wheel damping adjustment instruction, and the damping of the steering wheel is adjusted. Specifically, the automotive electronic controller unit 3 adjusts the steering wheel damping through the software and control algorithm in the electronic power steering system. The control algorithm in the automotive electronic controller unit 3 calculates the power assistance to be applied and the degree of damping adjustment in real time based on the received sensor data. The damping force of the steering wheel is adjusted through the motor in the electronic power steering system. The motor can apply additional power assistance to the steering system and simulate different damping feelings at the same time.

[0087] Furthermore, in some embodiments of the present invention, after step S1 and after step S2, a step of converting the resistance change signal output by each resistance measuring unit into a digital or analog signal related to the pressure intensity is also included. Specifically, the resistance change signal corresponding to each flexible pressure sensor is amplified by a signal amplification unit; the resistance change signal processed by the signal amplification unit is filtered by a filtering unit; the analog voltage signal of the resistance change signal processed by the filtering unit is converted into a digital voltage signal by an analog-to-digital conversion unit; and the digital voltage signal processed by the analog-to-digital conversion unit is calibrated and corrected by a calibration and correction unit.

[0088] The method for automatically adjusting the steering wheel damping provided by the embodiment of the present invention receives the pressure generated by the driver's hands holding the steering wheel through a steering wheel grip force detection module, and determines the force applied to turn the steering wheel in the current driving scenario by recording and analyzing the pressure changes generated during the driving process; adjusts the steering wheel damping size according to the force applied to turn the steering wheel, helping the user to turn the steering wheel more easily; and can adaptively adjust the steering wheel damping size according to the strength with which each driver currently holds the steering wheel, helping the driver to drive the car more easily and safely.
