Vehicle

摘要

Disclosed is a hybrid work vehicle capable of smooth work travel using a work device with a low output internal combustion engine, while avoiding battery exhaustion. The vehicle includes an internal combustion engine that supplies drive power to a travel device and a work device via power transmission means, a motor generator that is driven by a battery, a load information generation part that generates load information representing a sudden increase in rotational load, an assist characteristic determination part that determines motor assist characteristics defining an assist amount and an assist time period of assist control based on load information, and a motor control unit that controls the motor generator based on the motor assist characteristics.

主权项

1. A vehicle comprising:
an internal combustion engine that supplies drive power to a travel device and a work device via power transmission means;
a transmission provided to the power transmission means;a shift control unit that adjusts a shift ratio of the transmission;a motor generator connected to the power transmission means;a motor control unit that performs motor assist control for assisting the internal combustion engine by outputting power from the motor generator to the power transmission means;a battery that receives charging power using the motor generator, and provides drive power to the motor generator;a load information generation part that generates load information representing an increase in rotational load received by the internal combustion engine; andan assist control determination part that executes the motor assist control, in order to eliminate the increase in rotational load, in priority to mechanical assist control for assisting the internal combustion engine by reducing the shift ratio of the transmission through the shift control unit.
