  • Hands-free telephone apparatus for vehicles and control-method therefor
    Patent number: 6718187
    Abstract: With a mobile telephone (10) set into a telephone holder (11), if a telephone call is received, rather than sounding an audible ringing, a head-up display (60) notifies the driver by a display (67) made in a peripheral vision region (64) outside of a central vision region (63) of the driver. The driver can respond to the incoming call only in the case in which the driving burden on the driver is small enough that, even without the aid of an audible ringing, the driver can notice the received-call display in only the peripheral vision region.
