Method for controlling braking of driving training vehicle

Abstract

The invention discloses a method for controlling braking of a driving training vehicle, and the method mainly comprises the steps: obtaining the coordinates of a GPS main antenna of the vehicle and the course angle information of the vehicle in real time through vehicle-mounted double GPS antennas, and calculating the real-time coordinates of two angular points of a vehicle head and two rear wheels of the vehicle according to the distance from the GPS main antenna of the vehicle to the two angular points of the vehicle head and the distance from the GPS main antenna of the vehicle to the two rear wheels of the vehicle; the method comprises the following steps: acquiring vehicle speed data and vehicle steering wheel angle data in real time, calculating outer and inner steering radiuses of a vehicle according to the vehicle steering wheel angle data, calculating a vehicle predicted buffer length according to the vehicle speed data, and obtaining a track predicted buffer area of the vehicle by combining the steering of the vehicle; according to the track prediction buffer area and the obtained coordinate information of the obstacle, whether the obstacle is in the track prediction buffer area or not is judged, and if yes, a braking instruction is triggered. According to the invention, pre-judgment and timely intervention of danger can be realized by calculating the pre-collision area through trajectory prediction, and the user experience feeling of driving simulation of trainees is improved.

Description

technical field [0001] The invention relates to a method for controlling braking of a driving training vehicle, belonging to the technical field of vehicle collision safety. Background technique [0002] With the continuous improvement of people's living standards, convenient transportation has become a major demand for people, and travel safety is the top priority. Motor vehicle driving skills have attracted more and more people's attention. Every year, tens of thousands of students participate in the training of professional driving skills. After passing the motor vehicle driving skills test, they can obtain a driver's license. Passing the driving skills test can try to avoid the driver from driving the vehicle. Traffic accidents occur in the process of driving. The occurrence of accidents will not only have a certain impact on the vehicle itself, but also pose a very serious threat to people's safety and economy. [0003] In the field of driving training, the robot coach...
