Adaptive vehicle anti-collision method

Abstract

The invention discloses an adaptive vehicle anti-collision method. A plurality of vehicle speed parameters, vehicle distance parameters and braking distance parameters at different driving types are pre-established by a control system of a vehicle, longer vehicle distances are set when the vehicle speeds are higher, the vehicle distances are increased or decreased appropriately according to different road conditions, sensors on the vehicle obtain dynamic information, such as the vehicle speeds or accelerations, analysis is performed by combining driving behaviors, a driver is classified into a certain driving type through statistical analysis and an artificial neural network, control parameters of the vehicle are adjusted by referring to the driving type of the vehicle driver, and thus an electronic control unit of the vehicle can perform warning or control to brake in an appropriate time in accordance with the driving habits of the driver. By adopting the adaptive vehicle anti-collision method, the problem that the safety vehicle distance and a brake device cannot be adjusted by an anti-collision system of the existing vehicle by aiming at different vehicle speeds, road conditions, habits of the driver or vehicle conditions is solved.

Description

technical field [0001] The invention relates to a vehicle anti-collision method, in particular to an adaptive vehicle anti-collision method capable of predicting driving patterns and fine-tuning vehicle parameters to timely provide warning information. Background technique [0002] Existing vehicles are equipped with a variety of driving safety aids to avoid the risk of collisions when the driver is driving the vehicle, such as the common Forward Collision Warning System (FCWS: Forward Collision Warning System) or the Automatic Braking System (AEB: Autonomous Emergency Braking), which mainly uses the radar sensor located at the front of the car to detect the distance between the vehicle (or obstacle) in front and the vehicle with radar waves. If the distance between the two vehicles is lower than the set value, That is, the system activates the brake system of the car to perform emergency braking and issue a warning to avoid vehicle collision or chasing.

Problems solved by technology

[0004] As mentioned above, the existing vehicle anti-collision system controls the braking device of the vehicle according to the preset vehicle distance judgment standard, and cannot adjust the safe distance between vehicles and brakes according to different vehicle speeds, road conditions, driver habits or vehicle conditions. Therefore, the main purpose of the present invention is to provide an adaptive vehicle anti-collision method, which mainly obtains the dynamic information of
