Only us "Type-A" engineers worry about such things!  |
No way, you didn't complicate my life, you gave us inputs to think more and plan and understand better.
Now my innovative senses are triggered and think that right way to generate TPMS alarm is :
If Ts1, Ts2, Ts3 and Ts4 are the tire pressures when TPMS is set and t1, t2, t3 and t4 are the actual tire pressures sensed by TPMS, then
Alarm shoul be generated if max{(Ts1-t1), (Ts2-t2), (Ts3-t3), (Ts4-t4)} -min{(Ts1-t1), (Ts2-t2), (Ts3-t3), (Ts4-t4)} > x amount of pressure.
A warning for low tire pressures can be generated if max{(Ts1-t1), (Ts2-t2), (Ts3-t3), (Ts4-t4)} > y amount of pressure.
This simple mathematical formulation can take care of variations in tire pressures of all tires due to temperatures, altitudes, storms etc.
