A vehicle lamp includes a housing attached to a vehicle and including an opening, an outer lens covering the opening of the housing and including an inner surface subjected to an anti-fogging treatment, and a light source disposed in an internal space defined by the housing and the outer lens. The inner surface of the outer lens includes a first region and a second region adjacent to the first region and positioned below the first region. The inner surface of the outer lens is provided with a protrusion, a step, or a groove along a boundary between the first region and the second region.

A relay drive control device is configured to control drive of a relay for connecting a battery mounted on a vehicle and an external power supply. The relay drive control device includes a controller configured to, when driving the relay, supply an output voltage of the battery to the relay after increasing the output voltage to a voltage value at which the relay is drivable.

A charging control device includes: a determination section configured to make a determination as to whether an auxiliary device battery that supplies electric power to auxiliary devices of a vehicle is within a predetermined first temperature range; and a control section configured to, in a case in which the auxiliary device battery is within the first temperature range, cause a charging section to charge the auxiliary device battery.

Charging control for improving efficiency of charging auxiliary device battery

There is provided an arbitration device that arbitrates operation requests from a plurality of first power loads in a vehicle, the arbitration device including: a reception section; a memory section; a calculation section that calculates a total power consumption combining the first power consumption and the second power consumption; and a control section at which priorities of the plurality of first power loads are specified, when the total power consumption exceeds a threshold, the control section selecting which of the first power loads to approve based on the priorities and causing each operating first power load that is not approved to pause operation, and, when the total power consumption is less than or equal to the threshold, the control section allowing each operating first power load to continue operation.

Arbitration device for arbitrating plural power loads in vehicle

An air flow adjusting structure for a vehicle includes: a fender liner provided above a tire in a vehicle vertical direction, the fender liner including an arch such that an air flow passage is formed between the arch and the tire; and an adjusting rib projecting from the arch in a vehicle-downward direction, the adjusting rib being inclined relative to a vehicle-width direction, and extending in a direction that intersects with a vehicle-longitudinal direction.

Air flow adjusting structure for vehicle

An on-board control apparatus has a power generation means that has a communication part; a storage battery that is chargeable by receiving electric power from the power generation means; a control means that is configured to be communicatable with the communication part and controls charging of the storage battery; and a state-of-charge measurement means that measures a state of charge of the storage battery. The control means transmits a signal that is to prohibit charging the storage battery to the communication part when an ignition of a vehicle is turned off, and the state-of-charge measurement means measures the state of charge of the storage battery, during a period of time in which charging the storage battery is prohibited, after the ignition of the vehicle is turned off.
