Impact of weight and speed on Braking distance

When vehicle weight doubles – your stopping distance Doubles.

When vehicle speed doubles – your stopping distance Quadruples.

Note: But irrespective of 50kmph or 150kmph speed, presently vehicles braking

components, tire’s footprint area and its corresponding traction all remains the

same which terribly affects the braking distance.

Problem Statement

One of the primary challenge both the

automobile and tire industry face is creating

a right balance between simultaneously

increasing - tire traction in critical situations

for safety & stability while reducing rolling

resistance in normal situations to reduce -

tire wear & tear, fuel consumption, road

noise and Co2 emission.

Here the fact is its impossible to

simultaneously achieve both as these are

straight opposite extremes.

Solution Technological Solution Performance Improvement

Static Efficiency and Performance data on

asphalt road – 27% increase in vehicle

braking deceleration rate with around 20%

decrease in brake stopping distance.

Tires with potential of automatic & highly time sensitive dynamic footprint

area is the only affordable and viable solution for this problem.

SATPOS works by classifying scenarios into normal & critical driving

situations.

To enhance tire traction SATPOS utilises Electro Pneumatic Valve that works

by controlling the tire pressure [between a pre-set upper/lower cut-off

values to sustain stability and steer-ability] in a highly time sensitive manner

to dynamically change the road tire’s contact patch area increasing traction

according to nature of the critical driving situations.

The SATPOS interoperates with vehicle’s various ECUs, existing safety and

stability systems [E.g. ABS, EBD, ESP, TCS etc.] to perform pre computing to

set ready to control tire pressure, current computing to control the tire

pressure during critical situation and post computing to optimize pressure

after overcoming critical situations to continue with comfortable driving.

Testing Result Standpoint

Test Environment Test passenger vehicle was driven on

snow & asphalt road surfaces.

Areas included are shallow snow

covered, partially dry & paved road.

Using data obtained from the tests,

the road friction coefficient was

calculated & compared.

For a detailed information regarding testing & results please refer to: https://cutt.ly/yv7uvUJ

Methods used ABS equipped passenger vehicle is used for braking test.

The velocity for the tests was 50 km/h.

Two tyre pressures were considered, 1.5 bars & 2.4 bars to modify contact pattern between the tire and the road.

Four test scenarios were set.

Two scenarios consisted of braking on snow with the two different tyre pressures.

Two scenarios were of braking on asphalt, also with two different tyre pressures.

Test vehicle was equipped with a GPS system in order to measure the velocity, braking distance & deceleration.

Challenges, Hazards and Fail Safe Solutions TRIPLE LEVEL FAIL SAFE AND REDUNDANT SYSTEMS TO NULLIFY SAFETY AND STABILITY CHALLENGES.

Possibility of failure of all safety systems are almost zero

• Similar to company recommended tire pressure, a recommended lower cut-off tire pressure value is integrated into SATPOS system.

• In critical braking situation, the SATPOS electro pneumatic valves instantaneously opens to reduce the tire pressure and closes particularly at recommended lower cut-off pressure value which plays a crucial role in reducing emergency braking distance without compromising on safety, stability and steer-ability of the vehicle.

Effect of stability and steer-ability when

reducing tire pressure?

• Actual lower cut-off pressure value’s are determined after performing proper real world safety and stability assessments in concurrence with tire manufacturers.

• Initially a safety headroom above low pressure cut-off value may be provided for additional safety.

Determination of lower cut-off pressure?

• Required rate of change in tire pressure with corresponding peak change in tire traction are achieved with application specific Electro Pneumatic Schrader Solenoid Valve.

Rate of change of tire pressure?

Is SATPOS a fail safe system?

What happens in a partial or complete failure of

valve operation or whole SATPOS system?

• Level 1 - During emergency braking SATPOS valve performs electro mechanical low pressure cut-off.

• Level 2 - If that fails then a pressure calibrated mechanical low pressure cut-off is performed.

• Initially SATPOS should be implemented on RFT tires that have the potential to run without pressure in

extreme emergency situations [With side wall reinforcement and tire inserts].

• Level 3 - So in the event of complete failure of valves the RFT tires provides safety and stability.

• Stability & steer-ability remain functional for considerable amount of time and distance on RFT.

• Run-flat tires are standard on 14% of new vehicles, according to Edmunds data.

• Reporting - Simultaneously TPMS actively alerts the tire pressure status to driver to act accordingly.

• Self diagnosis - SATPOS performs periodic self diagnosis for its reliable operations.

• So when one fails, second and consecutive systems will automatically and instantaneously works to

sustain stability and steer ability of the vehicle eliminating hazards and safety challenges.
