Abstract:
An alarming apparatus for an automotive vehicle, comprising:a running state detector to detect a vehicular running state; a road surface frictional coefficient detector to detect a frictional coefficient of a road surface on which the vehicle is running, a vehicle using road surface frictional coefficient calculating section that calculates a vehicle using road surface frictional coefficient that corresponds to a road surface frictional force the presently running vehicle is using on the basis of the detected vehicular running state; a road surface frictional coefficient utilization rate calculating section that calculates a road surface frictional coefficient utilization rate which is a rate of the calculated vehicle using road surface frictional coefficient of the road surface to a maximum frictional coefficient detected by the road surface frictional coefficient detector; and an alarm controlling section that outputs an alarm command to an alarm device to issue an alarm when the calculated road surface frictional coefficient utilization rate is equal to or larger than a set value.
