Abstract

An apparatus for monitoring the depth of the tread on a road vehicle tyre comprises sensors placed in the wheel arches or the tyres. The senors provide signals indicative of the wear on the tyre or the depth of tread. Warning lights on the dashboard, for each tyre, indicate to the driver the state of the tyre tread including if a tyre change is imminent or if the tread depth is illegal. Different coloured lights indicate the degree of tyre wear. An alternative method based on the average life expectancy of the tyres and the mileage done on the tyres, taken from the odometer, is also disclosed.

Description

TYRE TREAD MONITOR
<DESCRIPTION>
SYNOPSIS
Question: How often do you check your tyres on your vehicle? Answer 1: <Never> Answer 2: <Occasionally e.g. once/twice a year> Answer 3: <VWe act someone else to check them> The idea of a monitoring system for tyres ensures that drivers know when their tyres need to be changed or when they become illegal.
Being able to monitor the wear of lyres through an onboard monitoring system reduces the risk of running on lyres, which are unsafe for road use. The benefits of this will be increased road safety and the knowledge for the driver that he/she knows exactly when the lyres on the vehicle need to be replaced.
DESIGN
The Tyre Monitoring system will be ideally placed in the vehicles dashboard. It will enable the driver to monitor the status of their lyres every time the vehicle engine was started.
The following steps through the process of how the Tyre Monitoring system will be displayed to the driver: Start Vehicle Engine The Tyre Monitor system will be shown briefly (for a period of 10 seconds) to the driver when the vehicle engine starts on the vehicles dashboard, allowing the driver to check the current status of the tread OF his/her lyres Tyre Monitoring System Display The display will contain 4 light monitors (1 monitor for each tyre). The tyre monitors will be aligned side by side and each monitor will represent the current tread depth on a tyre. Each of the 4 tyre monitors will be defined as, O.S.F (Off Side Front), N.S.F (Near Side Front), O.S.R (Off Side Rear) & N.S.R (Near Side Rear). For more information on this, see <Figure l >.
The tyre monitors will be split into a series of colours (ranging from dark green, light green, yellow & red) - If the 'Green' light appears on any or all of the Tyre Monitors, it is a sign to the driver that the tyre tread is legal/safe.
- If the 'Yellow' light appears on any or all of the Tyre Monitors, it is a warning sign to the driver that the tyre tread is low and needs to be changed.
- If the 'Red' light appears on any/all of the Tyre Monitors, it is sign to the driver to change the tyres immediately & that the tyre is i [legal/unsafe.
The tread depth of each tyre will be used as the indicator measure on the display.
Each tyre on a vehicle has a standard tread depth (e.g. starting from 7 millimetres). As the tyre/s gets worn, different colours of green lights (ranging from dark green to light green) will appear on the monitor/s for the current tread depth.
The yellow indicator on the monitor will light up when the depth gets down to 2 mil & between 2 mil & 1.6 mil (leading up to the legal limit) and a warning light (displayed in yellow) will be shown on the dashboard indicating which tyre needs to be changed by its name.
When the tyre tread depth gets lower than legal limit of 1.6 millimetres, the red light will be displayed to the driver and a warning light (displayed in red) will be shown on the dashboard indicating which tyre needs to be changed by its name.
See <Figure 2> for how the monitor will look.
There are two processes in which the Tyre Monitoring system can be incorporated into the vehicle. The following steps through each of them in turn: 1. Simple Process (and Cost Effective! On average tyres are estimated to last for TO miles (7,000 for example). This being the case, the lyre monitor system will work by simply connecting it in with the mileage counter.
When the mileage for each of the 4 lyre service lights reaches 7,000 miles, the Red light will appear (this can be programmed for more miles for lyres on the rear as they do not wear as fast).
When a new lyre is put onto the vehicle the Tyre Monitoring System can be reset for that particular tyre with a touch of a button, (much like setting the mileage counter back to 0).
The lights will then count down over a certain amount of miles until the tyre/tyres were considered ready to be changed again.
If one of these lights was approaching red, or in the yellow zone, a new light will constantly appear on the dashboard stating 'Check lyre O.S. R' or 'Change Tyre N.S.F' for example.
As most vehicles service light history already works from the mileage counter, this will be easy to implement.
2. Complex Process (but more accurate! This way ultimately turns out to be the most accurate but also the most expensive and involves a more technical approach.
The Tyre Tread Monitor will take on the same design (as with the Simple Process) on the vehicles dashboard but instead of being connected to work with the mileage counter, it will use sensors to measure the tread on the tyre.
Sensors will need to be positioned in the vehicle where the tyre is positioned and in the tyrc tread of the tyre itself.
The sensors that need to be positioned in the vehicle will ideally be placed in each of the 4 wheel arches of the vehicle so that they will be able to record when a sensor had been activated within the tyre tread.
The sensors which will be inside the tyre tread, will become activated when the tyre tread got to a certain Icvel, e.g. if the tyre tread reached 5 millimetres, a sensor in the tyre tread will be activated and in turn will activate the sensor in the wheel arch which will report back to the tyre tread monitoring system that the particular tyrc tread on the tyre was at 5 millimetres.
Using sensors will also enable the recording and monitoring the tyre pressure within the Tyre Tread Monitor.
Being able to monitor tyre pressure via the Tyre Tread Monitor gives the user the ability to identify the-exact tyre pressure of each-lyre on the vehicle and to track slow punctures, leaking valves etc. This will be cost effective for the user as they will not need to replace their tyres so often & it will also be beneficial for safety reasons as vehicles will not be driven with uneven tyre wear as a result of lyres with incorrect tyre pressures.
Sensors will need to exist in the tyre or in the tyre valve and can again be picked up from the sensors in the wheel arch. Any change in tyre pressure will immediately be reported to the user via the Tyre Monitoring System on the vehicles dashboard.
See <Figure 3> for how the pressure monitor will fit in with the Tyre Tread Monitor.
SUMMARY
The Tyre Tread Monitor will lead to safer vehicles on our roads.
It can also be implemented into the vehicles dashboard with little effort and it can be enhanced to check for accurate lyre pressures.
I am unable to see of any reason why this will not be beneficial for the driver and road safety. i
