Title:
SAFETY DEVICE OF VEHICLE
Document Type and Number:
Japanese Patent JP3028261
Kind Code:
B2
Abstract:
PURPOSE: To keep off the frequently occurrence of automatic collision avoidance operation in the case where a surface road at a rainfall or the like is low, in a safety device which has this collision avoidance operation such as braking or the like operated automatically if a car-to-car distance becomes shorter than the specified collision avoidance car-to-car distance, while making the collision avoidance car-to-car distance the larger, the small in the road surface μ.
CONSTITUTION: This car safety device is made up of installing a collision avoidance car-to-car distance decision means 12, which determines a collision avoidance car-to-car distance while at the time of determining this distance, determines it to be increasingly compensated if a road surface μ becomes lessened by a compensation means 10, a collision avoidance control means 16 which has a brake operated if a car-to-car distance has become shorter than the collision avoidance car-to-car distance, and a compensation limiting means 18 which restricts the increasing compensation of the collision avoidance car-to-car distance by the compensation means 10 at a time when the road surface μ is less than the specified value.
