It is disconnected: when the arbitrary neighborhood for the metal detection signal that any one in the first metal sensor 5 and the second metal sensor 10 obtains
Four signal peaks between three time intervals in vehicle driving distance it is equal, be judged as metallic foreign body occur, enter step
Otherwise S2 is judged as do not occur metallic foreign body, repeat this step；By taking Fig. 5 as an example, if there is metallic foreign body, metal in tyre surface
Detectable signal will appear pulse signal, while pulse signal generates each time, at the time of recording impulse moment (such as t1,
T2 ...) and corresponding vehicle instantaneous velocity of each moment (v1, v2 ...), the period between adjacent pulse signal twice
Be denoted as Δ t12, Δ t23, Δ t34 ..., the average speed in period between adjacent pulse signal twice be denoted as v12,
V23, v34 ..., in the first time period duration Δ t12 between adjacent pulse signal twice, average speed v12 calculates Δ
T12*v12 is denoted as A1；In second time period duration Δ t23, average speed v23 calculates Δ t23*v23, is denoted as A2, with
This analogizes, when system ECU detect three periods of arbitrary neighborhood processing costs An, An+1, An+2 it is equal when, then confirm presence
It is attached to the metallic foreign body of tyre surface；
S2, controller control alarm alert, such as return to step S1.
When confirmation tyre surface is there are after metallic foreign body, under vehicle stop state, controller is then according to the first gold medal obtained immediately
The metal detection signal for belonging to sensor 5 and the second metal sensor 10 judges whether there is pulse signal, if the first metal passes
There are pulse signals then to indicate for the metal detection signal of sensor 5, and the left anterior-superior part of 6 tyre surface of wheel is there are metallic foreign body, and preceding upper four
/ mono- loop section 11b, which is lighted, to alarm to prompt driver to check 6 front upper side of wheel；If the second metal sensor 10
There are pulse signals then to indicate for metal detection signal, and there are metallic foreign body, rear upper a quarter rings for the right back upper place of 6 tyre surface of wheel
Part 11c, which is lighted, to alarm to prompt front upper side after driver's inspection wheel 6；If the first metal sensor 5 and the second gold medal
Belong to sensor 10 metal detection signal pulse signal be all not present then indicate 6 tyre surface of wheel that there are metals for lower half portion is different
Object, then the lower half ring segments 11a of alarm, which is lighted, alarms to prompt driver to check 6 lower half portion of wheel.
