Title: Garbage collection vehicle
Inventor: OHARA HOMARE
IPC: B60P3/00
Filed: 2021-04-28
Abstract: To provide a garbage collection vehicle having a discharge plate operation function, which accurately calculates an approximate value of a garbage weight loaded in a garbage collection box.SOLUTION: According to whether or not a discharge plate operation function is used (S22) and whether or not the relative density of collected garbage is different from relative density of average garbage by a predetermined threshold or more (S21), the garbage collection vehicle switches approximation formulas to be used for calculating an approximate value of a weight of loaded garbage (S23-25). Thus, the approximate value of the weight of the garbage loaded in the garbage collection box can be calculated, taking into account the presence or absence of the use of the discharge plate operation function. In addition, the approximation formulas to be used for calculating the approximate value can be switched between when the relative density of the collected garbage is close to the relative density of the average garbage and when it is significantly different (when it is garbage such as used diapers), thereby allowing for accurate calculation of the approximate value of the weight of the garbage loaded in the garbage storage box.SELECTED DRAWING: Figure 10
