Abstract: A display control device includes an image creating unit, a display output unit, an update time measuring unit, and a blinking control unit. The blinking control unit determines a bright time and a dark time to be integral multiples of an update time so that a blinking frequency is within a tolerance frequency range. In a blinking control, the blinking control unit executes an on-display control to instruct the image creating unit to create a bright image for a number of times of a value obtained by dividing the bright time by the update time, and then executes an off-display control to instruct the image creating unit to create the dark image for a number of times of a value obtained by dividing the dark time by the update time, and repeats the on-display control and the off-display control until the blinking control ends.

Abstract: A driving assistance apparatus which is mounted in a vehicle includes an acquisition unit configured to acquire external information, a notification request generation unit configured to generate a notification request based on the external information, a switching unit configured to switch between an on state and an off state of a notification function according to an input from a vehicle occupant, a first information notification unit configured to display a first display for giving notification of the external information in a predetermined display area of a display device based on the notification request when the notification function is in the on state and the notification request is generated, and a second information notification unit configured to display a second display for giving notification of predetermined information different from the external information in the predetermined display area when the notification function is in the off state.

Abstract: A vehicle display system includes: a display arranged in a cabin of a vehicle and configured to display settings of a plurality of setting items of an air conditioner; and an electronic control unit configured to calculate an index value indicating a level of an operating load of the air conditioner on the basis of the setting of the setting item that influences a load state of the air conditioner among the plurality of setting items, and display, on the display unit, the index value and the setting of the setting item used to calculate the index value among the plurality of setting items.

Abstract: A vehicle information display apparatus includes display areas displaying information concerning an in-vehicle device and displaying an operation screen page for operating the in-vehicle device; an operating part for performing an operation on the operation screen page and a control part receiving an operation signal corresponding to the operation performed on the operating part, controlling a display on the plurality of display areas and determining, based on the operation signal, an operation valid display area from among the display areas. The control part executes the operation on the operation screen page in the operation valid display area based on the operation signal corresponding to a first operation performed on the operation part. The control part changes the operation valid display area based on the operation signal corresponding to a second operation performed on the operating part.

Abstract: A remaining fuel amount display device including: a fuel gauge; a sensor that detects the remaining fuel amount of the fuel tank; and an electronic control unit that calculates an indication value of the fuel gauge. The electrical control unit calculates the indication value by subtracting a subtraction value from a last indication value when the last indication value is greater than a detected value of the remaining fuel amount. The last indication value is calculated at one time before the indication value. The subtraction value is greater than a latest fuel consumption amount in an interval of the calculation of the indication value and equal to or less than a sum of the fuel consumption amount and a difference between the last indication value and the detected value. The subtraction value becomes larger when a value obtained by comparing the last indication value with the detected value is larger.

Abstract: An engine start controller shortens the time required from when an operation switch is operated to when an engine is started. The engine start controller controls starting of the engine of a vehicle and power supply to an electric device system. A control unit selectively locks the steering shaft of the vehicle and performs authentication with a portable device, which is carried by a user of the vehicle, for permitting use of the vehicle. An operation switch is connected to the control unit and generates an operation signal when operated by the user. The control unit unlocks the steering shaft in parallel with supplying power to the electric device system when the operation signal is generated and use of the vehicle is permitted through the authentication.

Abstract: A steering shaft locking device capable of performing a locking operation in an optimum manner. The steering shaft locking device includes a motor to which voltage is applied to generate a drive force. A locking bar is moved by the drive force of an actuator so as to engage the steering shaft. A steering shaft lock ECU connected to the motor performs a first control to move the locking bar to a lock position, at which the locking bar engages the steering shaft, and a second control to move the locking bar to an unlock position, at which the locking bar is disengaged from the steering shaft. A voltage control means controls the voltage applied to the motor during the first control such that the voltage is less than or equal to the voltage applied to the motor during the second control.
