Title: WORK VEHICLE CONTROL SYSTEM
Abstract:
Provided is a dump truck control system which is capable of dealing with block sections in accordance with a travel position and can reduce the information transmission amount. The present invention comprises a dump truck (1) that is equipped with: a permission request unit (4d) which, when a vehicle body (1a) is travelling in a prescribed block section (S1) within a travel path to be travelled, requests a travel permission request signal to be sent from a vehicle-mounted wireless device (2b) and for the purpose of requesting a travel permission signal that permits travel in a block section (S2) which is positioned ahead of the block section (S1); and a calculation unit (4c). If, on the basis of the travel position detected by a GPS device (2a), it is determined that travel is taking place in the block section (S1), the calculation unit (4c) varies the frequency of request of the travel permission signal by the permission request unit (4d) in accordance with the remaining distance (a) to an emergency stop location (E1) that is positioned in the block section (S1) and ahead of the vehicle body (1a). The present invention further comprises a control centre (11) which controls the travel of the dump truck (1).
