DRIVER ASSISTANCE SYSTEM: abstract simplified (18189225)

• This abstract for appeared for patent application number 18189225 Titled 'DRIVER ASSISTANCE SYSTEM'

Simplified Explanation

The abstract describes a driver assistance system that uses an external sensor to gather information about the road ahead. The system then calculates the relative speed and predicted time to collision between the vehicle and an object. If the object is a pedestrian, the system automatically applies the brakes if the current state point is above a certain limit line. Additionally, if the state point is below or at the limit line, the system automatically changes the direction of the vehicle to avoid a collision.

Original Abstract Submitted

A driver assistance system is provided with: an external sensor unit that acquires forward information; and a driver assistance control device that calculates, on the basis of the forward information, a relative speed and a predicted time to collision between the vehicle body and an object, and additionally executes a braking control for emergency avoidance that operates a brake device automatically at a timing determined on the basis of the predicted time to collision. If the object is a pedestrian, the driver assistance control device executes the braking control when the current state point specified by the relative speed and the predicted time to collision is inside an area 1 above a braking avoidance limit line L, and executes a steering control that automatically changes the travel direction of the vehicle body when the state point is inside an area 2 at or below the limit line L.
