Description

The present invention is a vehicle having an engine, a motor-generator, a driving device for driving the bodywork equipment by the power of the power or the motor-generator of the engine, a power transmission mechanism for bodywork equipment driving the vehicle with an Regarding the mounting equipment control system of the vehicle and the mounting equipment control method of the vehicle.

Among vehicles equipped with an engine (internal combustion engine) such as a diesel engine, there is a vehicle equipped with a mounting facility (for example, a packer device in the case of a dust vehicle) that is driven when the vehicle is stopped. In a vehicle equipped with this mounting equipment, in the prior art, when the vehicle is stopped to drive the mounting equipment, the power of the engine is transmitted to the other end side of the PTO shaft via the PTO shaft connected to the transmission. The erection equipment was driven by transmitting to the drive device for driving the erection equipment connected to.

In connection with this, in a garbage truck that extracts the driving force of a traveling engine that supplies pressure oil to the hydraulic equipment that drives the dust loading device and drives it with the PTO device, the value of the load on which the dust loading device acts is predetermined. When the value exceeds the value of, by adding the power of the electric motor to the power of the traveling engine, the dust loading device is driven against a large load while avoiding an increase in the rotation speed of the traveling engine. A garbage truck capable of being used has been proposed (see, for example, Patent Document 1).

However, the present inventors have consumed the fuel consumption of the engine required to drive the mounting equipment in the process of traveling the vehicle on a preset travel path such as the garbage collection process of the dust vehicle and the delivery process of the delivery vehicle. However, it was discovered that the amount is not necessarily small compared to the fuel consumption of the engine required to drive on this travel route. In particular, this tendency is remarkable when the packer device of a dust vehicle is used as the mounting equipment.

Therefore, the present inventors have developed a vehicle equipped with a motor generator for driving the mounting equipment. More specifically, as shown in FIGS. 2 and 3, the power of either the engine 10 or the motor generator 111 is transmitted to the drive device 110 via the power transmission mechanism 114, and the drive device 110 is transmitted. We have developed a vehicle configured to drive the mounting equipment 115.

In this vehicle, the power of the engine 10 or the power of the motor generator 111 is used to drive the mounting equipment 115 when the vehicle is stopped, depending on the charge amount (SOC) of the battery 113 connected to the motor generator 111 via the inverter 112. Since this is performed by either of the above, the fuel consumption of the engine 10 required to drive the mounting equipment 115 can be reduced as compared with the conventional technique. Further, in this vehicle, when the charge amount of the battery 113 is small, the mounting equipment 115 is driven by the power of the engine 10 and the motor generator 111 is generated to charge the battery 113.

However, as shown in FIGS. 2 and 3, the power transmission mechanism 114 provided in this vehicle proposed by the present inventors includes a motor generator 111 and a drive device 110 on the power input shaft (PTO shaft) 116 of the engine 10. Due to this configuration, parts (gears, chains, etc.) for transmitting power between the engine 10, the motor generator 111, and the drive device 110 are connected in parallel. In FIG. 3, the drive is used. Gear 114a, idle gear 114b, driven gear 114c) are required. Since these power transmission parts 114a to 114c are arranged in the power transmission mechanism 114, there are problems that the power transmission mechanism 114 becomes large and takes up space, the weight of the entire vehicle becomes large, and the cost becomes high. It was.
