- the outer part data calculation unit 115 calculates outer part data 81D indicating the range of the outer part 81 (boundary update scheduled area). On the other hand, if it is determined that the traffic area 80 does not exist outside the operation area 50, the process is terminated.
- the determination unit 114 determines whether or not the dump truck 2 has passed the predetermined position P3 (step S40). In step S ⁇ b> 40, the determination unit 114 performs determination based on the position transmitted from the dump truck 2. When it is determined that the dump truck 2 does not pass the predetermined position P3 (No in step S40), the determination in step S40 is repeated until the dump truck 2 passes the predetermined position P3.
- Step S50 the determination unit 114 determines whether or not the operating area data 50D has already been updated. In step S50, the determination unit 114 determines that the operation area data 50D is not updated when the dump truck 2 first passes through the course passing through the loading point LPP (No in step S50). Further, the determination unit 114 determines that the operation area data 50D has been updated when the dump truck 2 passes through the course passing through the loading point LPP after the second unit (Yes in step S50).
- the update data generation unit 116 expands the operation area 50 according to the range of the outer portion 81 of the traffic area 80.
- Update data 90D is generated (step S60).
- the operating area setting unit 112 reflects the generated update data 90D in the operating area data 50D (step S70). As a result, the operating area 50 is deformed into a shape corresponding to the outer portion 81.
- step S50 If the determination unit 114 determines that the operating area data 50D has been updated (Yes in step S50), the process ends without performing steps S60 and S70.
- the work vehicle control system 100 includes the course data generation unit 111 that generates the travel condition including the travel route TR of the dump truck 2 in the work area PA, and the area in which the dump truck 2 can operate.

- the update data generation unit 116 generates update data 90D in which the operation area 50 is extended so as to extend in the outward direction of the traffic area 80.
- the operation area 50 can be expanded to an area wider than the area through which the dump truck 2 has actually passed.
- the update data generation unit 116 generates update data 90D in which the operation area 50 is extended so that the boundary line 51 of the operation area 50 is along the outline 82 of the outer portion 81. Therefore, it is possible to prevent the operation area 50 from being excessively expanded.
- the update data generation unit 116 generates update data 90D that is deformed so that the boundary line 51 of the operating region 50 overlaps the outline 82 of the outer portion 81. Thereby, it can suppress more reliably that the operation area
- the dump truck 2 has been described as an example of a so-called drive-by type course in which the dump truck 2 arrives forward with respect to the loading point LPP. is not.
- the course may be a switchback type course in which the dump truck 2 switches back and reaches the loading point LPP.

- the operating area setting unit 112 sets the operating area 55.
- the boundary line 56 of the operation area 55 is set along the wall portion W, for example.
- the course data generating unit 111 travels along the loading point LPP. Generate TR.
- the course defined by the travel route TR is, for example, a course in which the dump truck 2 arrives in reverse by switching back to the loading point LPP. In this case, the dump truck 2 moves backward to reach the loading point LPP, and after loading by the loader 3 at the loading point LPP, the dump truck 2 travels forward from the loading point LPP.
- the traffic area setting unit 113 calculates traffic area data indicating the range of the traffic area 85 of the dump truck 2.
- the rear end of the dump body 22 is disposed so as to protrude rearward from the rear wheel 25R, and a space is provided between the dump body 22 and the ground. For this reason, the rear end of the dump body 22 can pass even above the protrusion that protrudes to a predetermined height from the ground. On the other hand, it may be difficult for the rear wheel 25R to pass above such a protrusion. Thus, even if the rear end of the dump body 22 can pass, the rear wheel 25R is not necessarily allowed to pass. Therefore, the traffic area setting unit 114 does not set the traffic area 80 behind the rotational axis AX of the rear wheel 25R of the dump truck 2.
- the determination unit 114 determines whether or not the traffic area 85 exists outside the operation area 55 based on the operation area data and the traffic area data.
