Technical Field
The present invention relates to a vehicle.
Background
Conventionally, as such a vehicle, a vehicle including a motor for traveling, a main battery that exchanges electric power with the motor, and a solar system has been proposed (for example, see patent document 1). Here, the solar system includes a solar charging unit that receives sunlight to generate power, a solar battery that stores power generated by the solar charging unit, and a boosted DCDC that boosts the power of the solar battery and supplies the boosted power to the main battery.
Disclosure of Invention
Problems to be solved by the invention
In such a vehicle, in order to extend the cruising distance, it is also conceivable to perform solar charging in which electric power from the solar system is supplied to the main battery during the trip. In this case, if a short-circuit abnormality occurs in the solar system (for example, boost DCDC or the like), a current flows from the main battery to the short-circuited portion, and the motor cannot output a torque, so that there is a possibility that running using the torque from the motor is difficult.
The vehicle of the present invention is mainly intended to be able to travel even when a short-circuit abnormality occurs in a solar system or the like.
Means for solving the problems
In order to achieve the above-described main object, the vehicle according to the present invention employs the following configurations.
A vehicle according to the present invention includes:
a motor for traveling;
an electrical storage device that exchanges electric power with the electric motor;
a solar energy system that generates electricity using solar light and is capable of performing solar charging that supplies the electricity generated by the electricity generation to the electricity storage device;
a charging relay that connects and disconnects the solar system and the power storage device by being connected and disconnected; and
a control device for controlling the motor, the solar system, and the charging relay,
the control device turns off the charging relay when a short-circuit abnormality on the solar power system side relative to the charging relay is detected when the charging relay is turned on in a current trip, and keeps the charging relay off at least in the current trip.
In the vehicle according to the present invention, when a short-circuit abnormality on the solar system side of the charging relay is detected when the charging relay is on in the current trip, the charging relay is turned off, and the charging relay is kept off at least in the current trip. Thus, since the charging relay is kept disconnected from the solar system side, even when a short-circuit abnormality occurs on the solar system side of the charging relay, the same traveling as that in a case where the short-circuit abnormality does not occur can be performed.
In the vehicle according to the present invention, when the system start is instructed, the control device may turn on the charging relay to perform a short-circuit abnormality diagnosis on the solar system side of the charging relay, and when it is determined that a short-circuit abnormality has occurred on the solar system side of the charging relay, the control device may turn off the charging relay to prepare (enter a travelable state) and keep the charging relay off at least in a current trip. In this way, it is possible to detect a short-circuit abnormality on the solar system side of the charging relay during a period from the system being instructed to start to the time of readiness, that is, during a stop.
In the vehicle in which the short-circuit abnormality diagnosis on the solar power system side of the charging relay is executed when the system start-up is instructed, the control device may execute the short-circuit abnormality diagnosis when it is determined that the short-circuit abnormality does not occur on the solar power system side of the charging relay before the control device becomes ready, and thereafter, when it is determined that the short-circuit abnormality occurs on the solar power system side of the charging relay, the control device may keep the charging relay off at least in a current trip.
In the vehicle according to the aspect of the present invention, when the system start is instructed, the control device may be configured to perform the short-circuit abnormality diagnosis on the solar power system side of the charging relay, and the control device may be configured to perform the short-circuit abnormality diagnosis on the solar power system side of the charging relay, when it is determined that the short-circuit abnormality has occurred on the solar power system side of the charging relay in the previous trip, prepare for the short-circuit abnormality diagnosis, without performing the short-circuit abnormality diagnosis on the current trip, and keep the charging relay off in the current trip. This can shorten the time from the start of the instructed system to the readiness.
