摘要： A vehicle system includes a warning device and at least one electronic control unit. The at least one electronic control unit is configured to present a light stimulus to a driver, and determine whether the driver is facing forward, determine whether the driver holds a steering wheel, and cause the warning device to perform a first warning when it is determined that the driver is not facing forward while the light stimulus is being presented. The first warning is either the vibration or the sound. The at least one electronic control unit is configured to perform a second warning when it is determined that the driver does not hold the steering wheel before a predetermined time elapses after the first warning is started. The second warning includes the vibration and the sound.

摘要： A power supply system includes a power supply circuit that includes a plurality of battery modules, each of which has a battery. The power supply circuit is configured such that the batteries in the battery modules are connected to each other in series in response to a gate driving signal from a controller. An alternating current voltage having a different phase is output by temporally changing the number of the batteries connected in series in each of a plurality of power supply circuits.

摘要： A battery pack includes cylindrical batteries, a thermal diffusing plate, and a casing. The thermal diffusing plate holds the cylindrical batteries. The casing houses the cylindrical batteries and the thermal diffusing plate. The casing includes a first inner surface, inner surfaces other than the first inner surface, a first outer surface, and outer surfaces other than the first outer surface. The first inner surface is located between the first outer surface and the thermal diffusing plate. The heat transfer coefficient between the first outer surface and an outside air of the casing is lower than the heat transfer coefficient between each of the outer surfaces other than the first outer surface and the outside air of the casing.

摘要： A grille shutter is a device configured to adjust a temperature of coolant water of an engine by adjusting an amount of outside air introduced into a radiator of the engine. An ECU performs a failure diagnosis for the engine based on a temperature of coolant water of the engine. When the grille shutter is immovable in an opened state of the grille shutter regardless of an operating command to the grille shutter, the ECU renders the failure diagnosis process for the thermostat valve not to be executed. As a result, an incorrect operation of various controls executed based on a temperature of coolant water of the engine can be suppressed.

摘要： The battery string is configured so that a plurality of battery circuit modules can be connected in series. The drive circuit SU5 from the drive circuit SU0 of the battery circuit module transmits a gate signal for ON/OFF of the switch to the downstream drive circuit SU while delaying the gate signal by a predetermined delay time Td. When a particular battery circuit module (drive circuit SU4 in FIG. 4) is passed through, the delay time is switched from the delay time Td to the delay time Tds. The delay time Tds is longer than the delay time Td. As a result, the period of the gate signal, which is the “delay time×the number of battery circuit modules to be operated”, can be suppressed from becoming short (the increase in frequency can be suppressed), and an increase in loss can be suppressed.

摘要： An electric power supply system includes an alternating current electric power supply circuit that converts direct current electric power of a first direct current sweep unit including a battery string into alternating current electric power using a first inverter and outputs it, and an alternating current sweep unit that includes a U-phase battery string, a V-phase battery string, and a W-phase battery string that are Y-connected. Output densities of batteries of the battery string are higher than output densities of batteries of the alternating current sweep unit. Alternating current electric power is output from the alternating current sweep unit and the alternating current electric power supply circuit, and after a predetermined period elapses, the output of the alternating current electric power from the alternating current electric power supply circuit is stopped.
