Vehicle-mounted computer is configured as obtaining RSSI value, when radio communication signal intensity is less than the first standard value, by vapour Vehicle is dimensioned to the first distance value at a distance from first base station, carries out the switching of radio signal connection, concrete operations at this time It is as follows：
(1) when being more than the first distance value at a distance from automobile is between first base station, vehicle-mounted computer and first base station are disconnected Radio signal connects, while vehicle-mounted computer sends out GPS positioning instrument and plans trip order again；
(2) obtain the position of the second base station checked in by the radio base station sites database configured in vehicle-mounted computer with Neighbouring information of vehicle flowrate, under the premise of destination is constant, GPS positioning instrument is by the stroke planning of pilotless automobile with second On the shortest path of base station stroke, preferential planning meets and vehicle flowrate most short with the second base station stroke and is less than first flow at the same time On the path of value；
(3) the current travel speed of the pilotless automobile measured by velocity sensor is obtained；
(4) when travel speed is more than First Speed value, vehicle-mounted computer controls the distributive value of engine electric spray system, limitation Pilotless automobile accelerates, while control brake makes pilotless automobile be decelerated to First Speed and the traveling that remains a constant speed；When When travel speed is less than First Speed value, vehicle-mounted computer controls the distributive value of engine injector system, limits pilotless automobile Accelerate, while controlling brake monitor makes pilotless automobile remain a constant speed traveling；
(5) when being less than the first distance value at a distance from the second base station when automobile, vehicle-mounted computer establishes the nothing with the second base station Line electric signal connects；
First standard value refers to：Communication delay between vehicle-mounted computer and server is equal to the nothing in the case of first time Line electricity communication signal intensity；
First base station refers to：The base station that radio signal is connect currently is established with vehicle-mounted computer；
Second base station refers to：Between first base station and automobile destination, with first base station apart from nearest base station.
The beneficial effects of the invention are as follows：The digital communication chip for measuring RSSI value is added, when vehicle-mounted computer and first base station Between radio communication signal connection exist influence ride safety of automobile risk when disconnect at once, carry out to the second base station Close to the safety operation of traveling, realize that the safety of radio signal connection of the vehicle-mounted computer between first base station and the second base station is cut It changes.By radio communication signal intensity, this external factor that can influence pilotless automobile travel safety is supervised in real time Control realizes the implementation for controlling safety operation by this external factor, improves intelligence and the pilotless automobile of brake apparatus The safety of traveling.
