Abstract

An electric drive vehicle includes a vehicle main body 10, a battery 12, a power generating unit 11 that charges to the battery 12, an operating condition setting switch 40 capable of setting an operating condition of the power generating unit 11, a power-generating-unit side ECU 113 that operates the power generating unit 11 on the basis of the operating condition, a navigation system 30 that acquires a vehicle traveling condition, and a vehicle-side ECU 50 that estimates the amount of charge consumed in the battery 12 during traveling under the vehicle traveling condition. The vehicle-side ECU 50 turns on an alarm lump 46 when an estimated time necessary for charging the battery to make up the amount of charge estimated is longer than a desired time it takes to charge the battery to make up the amount of charge estimated.

Claims

1. An electric drive vehicle comprising:

a vehicle main body;

a battery mounted on the vehicle main body and usable for traveling; and

a power generating unit that charges to the battery, further comprising;

an operating condition setting part configured for a user of the electric drive vehicle to set an operating condition of the power generating unit to a first mode in which the power generating unit is operated with priority of fuel economy and a second mode in which the power generating unit is operated with priority of output;

an operation part configured to operate the power generating unit under the operating condition set by the operating condition setting part;

a vehicle traveling condition acquiring part configured to acquire a vehicle traveling condition about a route to a destination of the electric drive vehicle;

an estimation part configured to estimate, from the vehicle traveling condition, an amount of charge of the battery consumed in traveling under the vehicle traveling condition;

an estimated time calculating part configured to calculate an estimated time necessary for charging the battery to make up the amount of charge estimated by the estimation part under the traveling condition by the power generating unit;

a time setting part configured to set an expected time to the destination; and

a first notification control part configured to perform a control to notify a driver of an alarm when the estimated time necessary for charging the battery is longer than the expected time to the destination.

2. The electric drive vehicle according to claim 1, further comprising:

an estimated amount-of-fuel calculating part configured to calculate an estimated amount of fuel needed to travel under the vehicle traveling condition; and

a second notification control part configured to perform a control to notify the driver of the estimated amount of fuel.

3. The electric drive vehicle according to claim 1, further comprising:

a vehicle utilizing condition grasping part configured to grasp a vehicle utilizing condition;

a travelable distance calculating part configured to calculate a travelable distance taking the vehicle utilizing condition into consideration; and

a third notification control part configured to perform a control to notify the driver of the estimated travelable distance.

4. The electric drive vehicle according to claim 2, further comprising:

a vehicle utilizing condition grasping part configured to grasp a vehicle utilizing condition;

a travelable distance calculating part configured to calculate a travelable distance taking the vehicle utilizing condition into consideration; and

a third notification control part configured to perform a control to notify the driver of the estimated travelable distance.
