Title:

METHOD FOR CONTROLLING RASH-ADVANCE PREVENTION AT TAIL END OF ROUTE AND VEHICLE-MOUNTED DEVICE FOR RASH-ADVANCE PREVENTION AT TAIL END OF ROUTE

Document Type and Number:

WIPO Patent Application WO/2019/015241

Kind Code:

A1

Abstract:

Provided is a vehicle-mounted device for rash-advance prevention at the tail end of a route, the device comprising: a positioning module (101) for acquiring a satellite position of a vehicle; a calibration module (102) for carrying out positioning calibration on the satellite position and an actual position of the vehicle when the speed of the vehicle is zero; a speed acquisition module (103) for acquiring a current speed of the vehicle in real time and using same as a computational speed; a calculation module (104) for calculating and obtaining the current distance from the vehicle to a tail end and the braking distance corresponding to the current speed; a determination module (105) for determining whether a difference value between the current distance from the vehicle to the tail end and the braking distance is less than a pre-set safety margin; and a braking output module (106) for sending a braking instruction to a braking system when the difference value between the current distance from the vehicle to the tail end and the braking distance is less than the pre-set safety margin. Also provided is a method for controlling rash-advance prevention at the tail end of a route. The device and the method have a high positioning precision, a simple structure and a low maintenance cost, and can satisfy the requirement of a test route.
