Abstract: A vehicle operating system for controlling a control target device by performing a predetermined operation of a driver on a steering wheel of a vehicle, includes: a visual line position calculator for calculating a visual line position of the driver; a display position calculator for calculating a display position on a display arranged on a far side of the steering wheel from the visual line position of the driver using a calculation result of the visual line position calculator and a position coordinate of the steering wheel, the display position not hidden behind the steering wheel; and a display controller for displaying display information indicating a content of the operation on the steering wheel at the display position.

Abstract: A vehicular audio-amplifier controller includes: a delay buffer that stores a sound signal supplied from a signal source; a first processing unit that applies an absolute value process to the supplied sound signal; a second processing unit that applies a low-pass filter process and an offset process to a processing result of the first processing unit; a power supply controller that performs control to change a voltage value of a vehicular power supply according to at least a signal value processed by the second processing unit and a type of the signal source; and a sound signal output unit that outputs a sound signal stored in the delay buffer with only a delay time that is determined based on a power supply control process time of the power supply controller.
