Adaptive anti-collision method for vehicle
First Claim
1. An adaptive anti-collision method for vehicles, wherein each vehicle having multiple sensors and a control unit, the sensors acquire a vehicle speed and a measured distance between the vehicle and an obstacle in the front, the control unit is electrically connected to an electronic control unit (ECU) of the vehicle and the sensors, and the adaptive anti-collision method is performed by the control unit and comprises steps of:
- creating multiple driving patterns and indices or alert levels corresponding to the driving patterns, wherein each driving pattern has a vehicle speed, a safe distance and a reference braking distance related parameter, and the driving pattern at the vehicle speed corresponds to a comparison relationship between the measured distance and the safe distance and one of four safe levels;
analyzing the vehicle speed and the measured distance acquired by the sensors to determine one of the driving patterns, wherein actual driving conditions of the vehicle are statistically analyzed to acquire a driving state of a driver of the vehicle and classify into a corresponding driving pattern associated with the driver so as to generate one of the indices or the alert levels corresponding to the driving pattern and vary control parameters of the vehicle according to the classified driving patterns, wherein the index generated according to the driving patterns is calculated by

Abstract
An adaptive anti-collision method for vehicles has steps of creating multiple driving patterns with each driving pattern corresponding to a vehicle speed, a safe distance and a braking distance parameter, such as longer safe distance configured for faster vehicle speed, and higher vehicle speed or shorter safe distance for different road condition, acquiring dynamic information, such as vehicle speed or acceleration, of the vehicle using sensors on the vehicle, combining the dynamic information and drivers'"'"' driving behavior to determine a driving pattern through a statistical analysis and a neural network, adjusting control parameters of the vehicle according to the driving pattern for an electronic control unit of the vehicle to issue an alert or activate a braking action according to the driving pattern. Accordingly, the anti-collision method can be adapted to different vehicle speed, road condition and drivers'"'"' driving habits for adjusting the safe distance and the braking system.
