Electrically-powered vehicle

摘要

A hybrid vehicle illustrated as a representative example of an electrically-powered vehicle includes a chargeable/dischargeable power storage device, a motor configured to generate a vehicle drive force by receiving supply of power from the power storage device, an internal combustion engine as a drive force source, and a generator configured to generate charging power for the power storage device by power generation using an output of the internal combustion engine. If the generator cannot be operated normally, the control unit causes the electrically-powered vehicle to perform limp-home mode traveling by traveling using only the motor. During the limp-home mode traveling, the control device calculates a remaining travelable distance in the limp-home mode traveling, based on at least a remaining capacity of the power storage device and a vehicle speed.

主权项

1. An electrically-powered vehicle comprising:
a chargeable/dischargeable power storage device, a motor configured to generate a vehicle drive force by receiving supply of power from said power storage device; and a control unit controlling the vehicle drive force to be generated in response to a driver's request, said control unit including a calculation unit calculating a remaining travelable distance in first traveling using stored power in said power storage device, based on at least a remaining capacity of said power storage device and a vehicle speed, wherein during said first traveling, said motor is driven to output the requested vehicle drive force to said electrically-powered vehicle; wherein said calculation unit calculates the remaining travelable distance in said first traveling based on the remaining capacity of said power storage device and the vehicle speed at start of said first traveling, as an initial value, and updates the remaining travelable distance in said first traveling based on the remaining capacity of said power storage device, the vehicle speed, and the requested drive force during said first traveling; and wherein said calculation unit corrects the remaining capacity of said power storage device at the start of said first traveling, by adding a correction value based on the vehicle speed at the start of said first traveling, and calculates the initial value of the remaining travelable distance in said first traveling based on said corrected remaining capacity.
