"A SENSOR AND A SYSTEM TO MONITOR THE HEALTH OF TYRES OF A VEHICLE, AND A METHOD THEREOF"
Hella India Automotive Pvt Ltd., an Indian company, of Nanospace, Baner-Pashan Link Road, Pune-411045, India,
The following specification particularly describes the invention and the manner in which it is to be performed:

FIELD OF THE INVENTION
The present invention relates to a sensor, a system to monitor the health parameters of a wheel/tyre, and a method thereof.
BACKGROUND
The tyres/wheels of a ear are subjected to wear and tear on a daily basis resulting from several factors such as misaligned or unbalanced tyres and lack of camber, caster, toe adjustments of the tyres, and the like. These factors also play a vital role in maintaining the health of tyres for the user. For this reason, tyre or original equipment (OE) manufacturers recommend a certain time period (generally 6 months or 4,000- 5,000 kms.) after which the said parameters of tyres must be inspected and wheel/tyre balancing must be done. All these factors over time severely affect the health of a tyre and expose the user of that tyre to several safety hazards.
Misaligned wheels lead to increased wear and tear of the tyres, increased fuel consumption and decreased control over the vehicle. Due to such wear and tear, the tyres lose balance over time, making it imperative for the user to get the wheel balancing done at suitable intervals to maintain the health of the tyre and also to avoid hazardous incidents. The balance of tyres is affected due to several factors that include tread wear (causing a change in the weight distribution around the tyres), unbalanced tyres (causing the vehicle to shake or vibrate), misaligned tyres (causing wear and tear of the tyre or the vehicle pulling to one side) and components like toe, camber and caster (all these affecting the orientation of the tyres).
Wheel alignment or front-end/ tyre alignment is done at workshops by the technicians wherein they adjust the angle of a car's wheels to the position recommended by the manufacturers. Such wheel alignment services basically aim at tread depth inspection (inspecting poor alignment) along with toe, camber and caster inspection (inspecting wheel orientation) after which the vehicle's tyres are aligned to a recommended specification. During such alignment and balancing services, the technician adjusts the weight on the wheel rim to balance out tyre rotation trajectory, a calibrated spin balancer is used to test both static

(non-moving) and dynamic (moving) wheel balance. Such balancing is performed using large equipment/instruments at service stations at certain recommended time intervals.
The parameters such as camber, caster, toe, tread depth and balancing of the tyre are mainly responsible for the heath of the tyre and the control of the vehicle. These parameters can go off-limit any time based on several factors, such as road dynamics, and the like. The drivers will have no knowledge of such off-limit parameters and will continue using such tyres. Such usage is not recommended and also leads to increased and uneven tyre wear and tear, increased fuel consumption and emission and increased steering efforts. It is further responsible for a reduced operational life of such tyres and reduced control of the vehicle.
Presently, the users/drivers do not have any technology that aids them in predicting the run-time changes happening in the tyre health, i.e. whether the balancing, alignment and the parameters affecting them are in proper shape or not. Moreover, the user remains unaware about the wear and tear happening in the tyre during run-time, the misaligned or unbalanced situation of the tyre remains unknown, also the driver is unaware of the operational life left of the tyre, making the driver use the tyres even when such usage is not recommended. Such usage also leads to increased and uneven tyre wear and tear, reducing 10-50% of the tyre tread life as they are under inflation, improperly aligned and not balanced. This causes increased fuel consumption and also requires increased steering effort. Due to all this, many times a tyre life ends prematurely or is over used than its recommended operational life and such reasons even lead to fatal car crashes. Thus, there is a need to overcome such difficulties faced by the driver to avoid any unwarranted incident.
OBJECTS OF THE INVENTION
It is an object of the present invention to provide a system and a method to maintain the operational life of the tyre as well as the safety of the vehicle for the driver.
It is yet another object of the present invention to provide a system and a method to monitor the run-time health of each tyre using tyre health monitoring sensors.
It is yet another object of the present invention to provide a system and a method that monitors and detects the parameters affecting health and life of the tyres.

It is still another object of the present invention to alert the user of parameters working out of normal operable limits and reduce the fatal crashes caused due to such out of parameter tyres increasing the safety for the user.

DETAILED DESCRIPTION OF DRAWINGS
The detailed description set forth below in connection with the appended drawings is intended as a description of various embodiments of the present invention and is not intended to represent the only embodiments in which the present invention may be practiced. Each embodiment described in this disclosure is provided merely as an example or illustration of the present invention, and should not necessarily be construed as preferred or advantageous over other embodiments. The detailed description includes specific details for the purpose of providing a thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention may be practiced without these specific details.
Fig. 1 illustrates an overview of a vehicle including a Tyre Health Monitoring System (THMS) according to an embodiment of the present invention. THMS has at least one sensor incorporated in each of the tyres to continuously monitor and detect the parameters affecting the health of the tyres in runtime. The system further comprises a receiver (200) which is capable of receiving the information of several parameters such as camber, caster and toe angle, balancing, tread depth, alignment, and the like and predicting the operational life left of the tyres based on these parameters. The information received by the plurality of sensors incorporated in the vehicle is then transmitted to a receiver (200) which is configured to receive the parameter data, process, and analyze such data based on the threshold values of the parameters affecting the tyre health. Such information is transmitted using different audible and visual warning alerts based on various situations of the tyre parameters.
In a preferred embodiment of the present invention, the receiver (200) is an electronic control unit (ECU) which is capable of wireless communication and receives the information of tyre health parameters via any of the wireless communication protocols such as RF 313 MHz, RF 433 MHz, Classic Bluetooth 2.4 GHz, Bluetooth Low Energy (RLE) 2.4 GHz, Wi-fi, and the like. The receiver (200) then processes the received information, calculates such information

on the basis of the received information, and estimates the health parameters, further estimating the possible implications of these parameters on tyre health, excessive fuel consumption, and emission affecting each tyre in run-time and alerting the driver of the possible implications.
In another embodiment of the present invention, the sensor also incorporates sensor units such as accelerometer (130), gyroscope (140), magnetometer (150), pressure sensor (170), and the like that enables the run-time monitoring of various parameters affecting tyre health. These sensor units monitor the air pressure in the tyres, sense the acceleration, angular acceleration, and the magnetic field and such information is then processed to calculate various tyre parameters enabling the run-time monitoring of the tyre parameters.
Fig. 2 illustrates a THMS sensor (110) comprising various sensor units and components for sensing and recording the information of the parameters affecting tyre health. A battery enables the functioning of various sensor units placed inside the THMS sensor (110) including a pressure sensor (170), an accelerometer (130), a gyroscope (140), a magnetometer (150), and the like. An amplifier inside the sensor amplifies the pressure information and transmits the information for further processing. These sensor units effectively monitor the air pressure, the acceleration, angular acceleration of tyres, and also the magnetic field around the tyres based on which the information such as camber angle, caster and toe angle, eccentricity and tread depth for each tyre is determined.
According to an embodiment of the present invention, a Bluetooth Low Energy (BTLE) chip receives the information from the sensors, processes, controls, monitors and then compares it to the nominal threshold values as set by the OEM or vehicle manufacturers. Such processed information about the tyre health and its parameters is then transmitted via wireless data transmission to an intended receiver (200) which may be a Human-Machine Interface (HMI I/F), a mobile phone, and the like. The user or the driver of the vehicle has access to such receivers and this receiver (200) is used to display the run-time status of tyre parameters informing the user of possible implications on tyre health, fuel consumption, and emission after which the user can take the actions required.
In a preferred embodiment of the present invention, a THMS sensor (110) has a battery, preferably a coin cell battery which enables the functioning of sensor units such as the pressure sensor (170), accelerometer (130), gyroscope (140), magnetometer (150), and the

like. A pressure sensor (170) monitors the tyre pressure of the vehicle and this reading of the measured pressure is then amplified using an amplifier which is sent to a Bluetooth Low Energy (BTLE) chip. According to another embodiment of the present invention, BTLE chip has an analog-to-digital converter (ADC) incorporated in it that converts that amplified pressure information from analog to digital. ADC is also used to convert accelerometer (130), gyroscope (140), and magnetometer (150) information from analog to digital. BTLE chip incorporates several units such as a Central Processing Unit (CPU), a memory, a RF core, general inputs and outputs, a sensor controller engine, timing circuits, and a temperature monitor, all connected to the sensors units. The sensor also incorporates a transmitter and a receiver (200) which enables the transmission and receiving of data via wireless communication. In another embodiment of the present invention, a THMS sensor (110) includes an ISM transceiver (180) which is capable of transmitting and receiving tyre health information and the desired parameters in run-time, preferably at 2.4 GHz frequency.
Fig. 3 illustrates a system for monitoring the health of each tyre by recording and calculating the parameters affecting the tyre health in real-time and displaying it to the user or alerting the user based on the situation. According to an embodiment of the present invention, the system includes a THMS sensor (110) and a receiver (200). The THMS sensor (110) is capable of recording the air pressure, acceleration, angular acceleration, and magnetic field, alignment and balancing around each tyre, which is recorded via various sensor units such as pressure sensor (170), accelerometer (130), gyroscope (140), magnetometer (150), and the like. Such recorded parameters are filtered, calculated, and then compared to the threshold values as set by the car manufacturer or the OEMs.
The receiver (200) incorporates another ISM transceiver (180), capable of transmitting and receiving the information from the sensor. The calculated information is transmitted from, the sensor to a receiver (200) capable of receiving such information preferably at 2.4 GHz. The receiver (200) has a Human Machine Interface (HMI I/F) which is capable of being used by the intended user and is connected to a display unit (210) which may be a smart phone, HMI I/F in the vehicle Engine Control Unit (ECU), and the like. The information of various health parameters as calculated and compared by the Tyre Health Monitoring Sensor is received by the receiver (200) via wireless communication and is then displayed on the intended display unit (210). In an embodiment of the present invention, the wireless communication protocol via which the sensors communicate may be a a RF 313 MHz, RF 433 MHz, Classic Bluetooth 2.4 GHz, Bluetooth low Energy (BLE) 2.4 GHz, Wi-fi, and the like. Such wireless

communication enables the sensors to communicate wirelessly to the sensor units and various other units and also to the receiver (200) which is intended to receive such information and display it as an alert to the intended user. The entire system is capable of alerting the user about various out of limit parameters such as alignment, balancing, camber, caster, toe angle, tire tread depth, and also helping the user to verify if the tyre has been corrected to normal values during the service to maintain the tyre health parameters. The information about any parameter being out of the desired limits may be alerted to the user based on several alert techniques such as a visual warning based alert or an audible alert system, based on the situation of the tyre/wheel parameter. The sensor units are enabled to actively check the parameters such as camber, balancing, toe angle, tread depth, and the alignment of the tyre enabling proper information of the tyre to the user and reducing the risk of any incident due to such out of limit parameters.
Fig. 4a illustrates the camber measurement of the tyre according to an embodiment of the present invention. Camber is measured by measuring the angle between the vertical axis of the wheels used for steering and the vertical axis of the vehicle when viewed from the front or rear. The sensor unit, i.e. the accelerometer (130) is capable of sensing linear acceleration (m/s2), and when accelerometer (130) is kept on a flat surface, the z-axis points downwards and is aligned with the gravitational field vector. According to an embodiment of the present invention, when the tyre is in a steady condition, i.e. in a stationary mode or is not moving, the readings shown by the accelerometer (130) are 0, 0, 1 in terms of gravitational (g) values on the x, y and z- axis respectively.
Fig. 6 illustrates sensing of the camber angle deviation is preferably done by sensing the linear acceleration using Micro-Electro-Mechanical System (MEMS) by sensing the accelerometer's (130) deviation or the accelerometer's (130) tilt around the z-axis and for measuring the said tilt around z-axis, acceleration around the x-axis has to be measured and calculation of the sin angle has to be done providing the actual deviation. In a preferred embodiment, the camber angle deviation is calculated as:


Fig. 4b illustrates the measurement of the toe angle according to an embodiment of the present invention. Toe angle is the symmetric angle that each wheel makes with the longitudinal axis of the vehicle.
In a preferred embodiment of the present invention, the toe angle of a tyre is measured by a magnetometer (150) which is capable of measuring the strength of Earth's ambient magnetic field (measured in micro Tesla). The magnetic flux density in air is directly proportional to the magnetic field strength, and such a magnetometer (150) is capable of detecting the fluctuations in the Earth's magnetic field.
Fig. 7 illustrates the magnetometer (150) vector or the heading (He) angle which is also capable of being calculated using only Hx and Hy components of the Earth's magnetic field, i.e. the directions planar with the Earth's surface. The heading angle is calculated as:

The Heading angle is termed as the yaw angle in terms of rotational angle and according to a preferred embodiment of the present invention; it may also be termed as the toe angle, which is necessary to check if the tyre makes a symmetric angle with the longitudinal axis of the vehicle.
Fig. 4c illustrates the detection of an unbalanced tyre using an accelerometer (130) or a gyroscope (140) based on the distribution of mass within the tyre or along the distribution of mass along the entire tyre (including the rim of the tyre) to which the tyre is attached. According to en embodiment of the present invention, a tyre may be made to hop or wobble when it is rotated due to the asymmetries of mass in the tyre. Such asymmetries, causing hopping or wobbling of a tyre are responsible for disturbance in a ride, usually vertical and lateral vibrations.
Fig. 8 illustrates the detection of an unbalanced tyre using an accelerometer (130) or a gyroscope (140) and the four positions that are considered for the measurement include 0°, 90°, 180° and 270°.

In a preferred embodiment of the present invention, both gyroscope (140) and accelerometer (130) may be used to detect the four positions as described to detect an imbalanced tyre. The diagram represents a complete circle that a tyre rotates, and the four positions (0°, 90°, 180° and 270°) are based on time taken to complete each quarter. The time taken to complete two quarters is then compared to detect the imbalance in a tyre.
A gyroscope (140) sensor is used to measure the time component, which is used to record the time taken to complete each quarter and detect the asymmetries and imbalance in each tyre making it to hop or wobble. An accelerometer (130) or a gyroscope (140) sensor may be used to sense the tilt angle at the four desired positions during the rotation of a tyre. Thus, the lateral and vertical vibrations are reduced using such sensors further minimizing the ride disturbance.
In a preferred embodiment, the tread depth is dynamically measured. A gyroscope (140) measures the angular velocity(w) and an accelerometer (130) measures the linear velocity(V) or speed of the vehicle at constant pressure (P in psi). The radius of the wheel/tyre is estimated and the tread depth is thus measured by:

Fig. 4d illustrates the standards for tread depth monitoring of a tyre according to an embodiment of the present invention. Accelerometer (130) and gyroscope (140) may both be used to detect the angular and linear velocity at which a tyre rotates to calculate how much the tyre is worn. A 0% worn tyre has a tread depth of 8 mm while a 100% worn tyre has a tread depth of 1.6 mm, i.e. the most widely accepted minimum tread depth standard after which a tyre is not considered fit to be used further.
Fig. 5 illustrates the flow chart indicating the steps involved in the monitoring of a tyre health in run-time according to an embodiment of the present invention. The steps involved in the monitoring of the balancing of a tyre, estimating the camber angle, estimating the tread depth and estimating the toe angle are illustrated. Such estimated data is then calculated and compared to the nominal threshold values as set either by the manufacturer or the OEM and is further used to check the out of limit parameters in real-time and alert the user based on such calculation.
In a preferred embodiment of the present invention, as soon as a vehicle is started, the sensors are initialized (510). After the sensors are initialized (510), these sensor units, i.e. the

accelerometer (130), gyroscope (140), magnetometer (150), and the like are calibrated (512, 514, 516). The parameters from such sensor units are then recorded as readings (518, 520, 522), and further filtered for eliminating the noise recorded (524, 526, 528). Filtering is an essential step for the purpose of eliminating the noise and for signal conditioning. The time stamp of quarter rotation is also recorded to estimate the eccentricity (530), which is important to check the balancing and unbalancing parameters in each tyre. The recorded parameters from each sensor units are then fused (532, 534, 536) and determined to assess the camber angle, assess the tread depth, and assess the toe angle, called the parameter data (540, 542, 544, 546). Such parameter data is then compared to the nominal threshold values as provided by the OEM or the car manufacturer and an alert is generated based on the assessed data. The alert is transmitted (548) via wireless communication to the receiver (200) which then processes the alert information and displays it with the help of a graphical user interface (GUI) to the intended user in run-time/ real-time. The alert may either be a visual alert or an audible alert based on the situation of the said alert and parameter data.
