TIRE INTERNAL PRESSURE CONTROL SYSTEM

摘要

PROBLEM TO BE SOLVED: To sufficiently improve braking performance of a vehicle 3 by shortening a braking distance even on a wet road surface or a snow road surface. SOLUTION: When a second internal pressure mode set corresponding to a condition of the wet road surface or the snow road surface is selected by an internal pressure mode selection switch 29, a CPU 39 of a controller 35 performs control so that internal pressure of at least one of a sub air chamber 19B at the vehicle mounting inside in front wheel tires 5L and 5R and/or rear wheel tires 7L and 7R and a sub air chamber 19B at the vehicle mounting outside may be different from internal pressure of a main air chamber 19A.
