When the operation flow of the input display device 10 according to the second embodiment is started, first, display information of the in-vehicle device to be controlled is displayed on the display unit 100 (Step 1). This display information is display-controlled by the display ECU 110, and for example, a vehicle-mounted device to be controlled can be selected / switched by a switching button or a selection button provided around the display unit 100. It is also possible to display specific display information set as an initial screen when the vehicle power is turned on.

  Next, the driving state of the vehicle 1 is determined. As for the driving state of the vehicle 1, the touch display ECU 300 acquires vehicle speed information from the vehicle speed sensor 401 via the vehicle communication bus 600. Based on the acquired speed information, it is determined whether or not the traveling speed of the vehicle is zero (Step 2). Touch display ECU 300 refers to a determination program stored in storage unit 310 and a microcomputer (CPU) performs a determination process. The output signal from the vehicle speed sensor 401 is compared with the reference speed signal to determine whether or not the vehicle traveling speed is zero. The reference speed signal is set to zero or a numerical value close to zero where the traveling speed of the vehicle is extremely small. If the vehicle speed is determined to be zero by the above determination process, the process proceeds to Step 3, and if the vehicle speed is not determined to be zero, the process proceeds to Step 15.
