Title:
TIRE AIR PRESSURE ABNORMALITY NOTIFICATION DEVICE AND TIRE AIR PRESSURE ABNORMALITY NOTIFICATION METHOD
Document Type and Number:
Japanese Patent JP2016043749
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a tire air pressure abnormality notification device capable of precisely detecting the abnormality of a tire air pressure without adding a new sensor thereto.SOLUTION: A tire air pressure abnormality notification device 10 includes: a vehicle position detection part 11 which is connected to a beacon signal receiving device 25, an autonomous navigation support sensor 30 and a map DB21 and detects a vehicle position based on beacon signals received at first and second spots by the vehicle 1 during travelling; a ride distance gain part 12 for gaining a ride distance between the first and second spots by approaching the map DB21; an autonomous navigation distance gain part 13 for gaining an autonomous navigation travelling distance based on a signal outputted from the autonomous navigation support sensor 30 when the vehicle 1 travels between the first and second spots; an air pressure abnormality determination part 14 for determining abnormality of a tire air pressure based on the gained ride distance and the autonomous navigation travelling distance; and an air pressure abnormality notification part 15 for notifying the abnormality of the tire air pressure to a driver.SELECTED DRAWING: Figure 2
