JUDGMENT LINE CALCULATIONS FOR A VEHICLE SAFETY SYSTEM
First Claim
Patent Images
1. A safety system for a vehicle comprising:
- at least one object sensor configured to detect a distance from an object in a path of the vehicle and the speed and acceleration of the object;
at least one vehicle sensor configured to determine a speed and acceleration of the vehicle; and
a control to determine a first amount of time until the vehicle must begin braking to avoid contact with the object and a second amount of time until the vehicle must begin steering to avoid contact with the object, wherein the first amount of time and the second amount of time are based on the detected distance, the speed and acceleration of the object and the speed and acceleration of the vehicle.

Abstract
A vehicle has a safety system including at least one object sensor to detect a distance from an object in a path of the vehicle and the speed and acceleration of the object. The sensor data is input into a control to determine a desired braking judgment line and a steering judgment line between the vehicle and the object. The safety system then compares the vehicle and object acceleration. Following, the safety system calculates a judgment line between the object and the vehicle based upon equations for the determined scenario. The judgment line is then used to determine a warning distance and warn a vehicle operator.
