A vehicle power supply control system includes a solar panel, a drive battery, an auxiliary battery, an auxiliary system that is powered by the solar panel and the auxiliary battery, an acquisition unit, and a controller. The acquisition unit is configured to acquire power generated by the solar panel and power consumption of the auxiliary system. The controller is configured to control power supply from the solar panel to the drive battery based on the power generated by the solar panel and the power consumption of the auxiliary system when the power supply from the solar panel to the drive battery is possible.

A vehicle includes a solar panel and a vehicle control device. The vehicle control device is configured to control supply of electric power generated by the solar panel, configured to count the number of power supply operations in which the electric power is supplied from the solar panel to a target device that is a power supply destination, configured to determine whether the number of power supply operations satisfies a first condition, to configured execute power supply from the solar panel to the target device when determination is made that the number of power supply operations satisfies the first condition. The vehicle control device is configured not to execute the power supply from the solar panel to the target device when determination is made that the number of power supply operations does not satisfy the first condition.

The magnitude of a linear damping coefficient Cis set so as to decrease the greater a maximum amplitude value &#x3b1; of an intermediate frequency sprung acceleration is. In the case where a damping force control apparatus carries out control for dampening vibrations of a sprung member using a nonlinear H-infinity control theory, the linear damping coefficient Cis set to a high value when the maximum amplitude value &#x3b1; of the intermediate frequency sprung acceleration inputted to a suspension apparatus is low. Accordingly, a requested damping force Falso increases, which makes it possible to quickly dampen vibrations in the sprung member. Meanwhile, in the case where the maximum amplitude value &#x3b1; of the intermediate frequency sprung acceleration is high, the linear damping coefficient Cis set to a low value. Accordingly, the requested damping force Falso decreases, which makes it possible to suppress degradation in the riding quality when intermediate frequency vibrations are inputted, and particularly makes it possible to suppress riding quality degradation when the vibration speed is high.

Damping force control apparatus

A suspension apparatusincludes an electric shock absorberhaving a motorand a ball screw mechanism, an electric circuit, an inverting amplification circuit, and an inertia compensation capacitor Cp. The electric circuitelectrically connects the two electricity supply terminals of the motor. The inverting amplification circuitis connected to the electric circuit. The inertia compensation capacitor Cp is connected to the output terminal O of the inverting amplification circuit. As a result of approaching or separating motion between sprung and unsprung members, not only a generated current but also an inertia corresponding current Iwhich represents an inertial force of a rotation body, such as the ball screw shaftand the rotor of the motor, flows through the motorand the electric circuit. A current Iwhich is antiphase to the inertia corresponding current Iflows through the inertia compensation capacitor Cp. This antiphase current Icancels out the inertia corresponding current I.

Suspension device

A control mode for a damping force characteristic is set to be a variable control when a product of the sum x' of sprung member speeds and a sprung-member-unsprung-member-relative-speed x&#x2032; is positive. Accordingly, when the vibration in a middle/high frequency range is not being input to a suspension apparatus, an operation of a variable throttle mechanism is controlled so that a step number representing the damping force characteristic of a damper varies with a vibration state of a sprung member HA based on a Nonlinear Hcontrol theory. When the product of x&#x2032; and x&#x2032; is negative, the control mode is set to be an operation prohibiting control. When the vibration in the middle/high frequency range is input to the suspension apparatus, operation of the variable throttle mechanism is prohibited, and suppresses an increase in the operation frequency or in the operation amount of the variable throttle mechanism.
