Equipped with a solar power generation device that includes a light collecting member that collects and irradiates sunlight, a drive device that drives the light collecting member, and a control device that controls the drive device, and that has at least one solar cell panel. A light collecting device that irradiates light to a parked vehicle using a light concentrating member, the control device determining the power generation efficiency of solar power generation by the solar power generation device based on the position of the solar cell panel. The drive device is controlled so that the power generation efficiency is equal to or higher than the initial power generation efficiency that is the power generation efficiency at the initial position of the light collecting member.

Light collecting device

A vehicle management device for managing parking positions in a parking lot of a plurality of vehicles equipped with a solar battery and a power storage device for storing electric power generated by the solar battery, wherein based on the conversion efficiency of the solar battery of each vehicle and the sunlight conditions of the parking lot, the parking position of each vehicle is set so that the amount of solar electric power generation by multiple vehicles per unit time or the sum total of the amount of power generated by the solar cells mounted on multiple vehicles is large. As a result, the amount of electric power generated per unit time and the sum of the amount of electric power generated of the vehicles as a whole can be improved.

Vehicle management device managing parking position in a parking lot and vehicle

A vehicle equipped with a driving unit for traveling, a power storage device capable of supplying power to the drive unit, and a solar cell system capable of supplying power generated by a solar cell to the power storage device. A vehicle management device that determines the cause, based on whether or not a decrease in the amount of power generation has occurred while the vehicle is running and whether or not a decrease in the amount of power generation has occurred while the vehicle is parked, determines whether the decrease in the amount of power generation is caused by the state abnormality of the solar cell or the external environment.

Vehicle management device

A driving control apparatus of a hybrid vehicle is provided with: an internal combustion engine, a power dividing mechanism generator; an electric motor capable of outputting power according to electric power supplied from at least one of the generator and a storage battery, to a drive shaft; a changing device capable of changing an operating state of the generator, from one state to the other state out of a first state in which the rotating shaft of the generator can rotate and a second state in which a rotating shaft of the generator is fixed in a stop state; and a controlling device for controlling the changing device to change the operating state of the generator from the one state to the other state in a predetermined period in which the rotating shaft of the generator does not rotate.

Driving control apparatus and method of hybrid vehicle

In a hybrid vehicle in which a fixed speed change mode can be realized by the locking of a rotational element, the mislocking of the rotational element is prevented. A hybrid drive apparatus which has an engine, a MGand a MGand which functions as a power unit of a hybrid vehicle is provided with a brake mechanism of a cam-lock type which can control the MGin a lock state and a non-lock state by changing the state of a sun gear between the lock state and the non-lock state. In mislocking prevention control, an ECU calculates MGangular acceleration D&#x3c9;g, which is the absolute value of angular acceleration of the motor generator MGon the basis of a MGrotational speed Ngmand judges that the sun gear Sis in a mislocking state if the MGangular acceleration D&#x3c9;g is greater than a criterion value D&#x3c9;gth.
