Abstract: A control apparatus includes a control unit that executes display control of displaying information on a display apparatus. Further, while the vehicle is running toward a destination set in navigation information, the control unit generates a time image indicating whether an estimated arrival time is shortened or prolonged with respect to an original scheduled arrival time as information regarding a scheduled time at which the vehicle arrives at the destination, and the control unit generates an effect image indicating an energy consumption reduction effect, and the control unit displays the generated time image and the effect image in real time on the display apparatus.

Abstract: A driving assistance device includes a determination unit that determines whether a brake light of a preceding vehicle located in front of a vehicle is turned on, based on a lighting state of a headlight of the preceding vehicle and an acceleration/deceleration of the preceding vehicle, a calculation unit that calculates a target acceleration/deceleration of the vehicle, based on a determination by the determination unit of whether the brake light of the preceding vehicle is turned on, and a control unit that controls the vehicle so that an acceleration/deceleration of the vehicle corresponds to the target acceleration/deceleration.
