Abstract: In a display system, a HUD displays a virtual marker D indicating a vehicle shape which guides a traveling direction of a user's vehicle. The display system measures an inter-vehicle distance between the user's vehicle and a forward vehicle and determines a display position and a display size of the virtual marker in accordance with the inter-vehicle distance. The virtual marker is shifted to a near side of the user's vehicle when the inter-vehicle distance is small, whereas the virtual marker is shifted to a far side of the user's vehicle when the inter-vehicle distance is large. A portion of the virtual marker is brought into a non-display state as if the portion is absorbed into the user's vehicle when the inter-vehicle distance is reduced, and the virtual marker is not displayed when the distance is further reduced.

Abstract: When a vehicle stops due to a red light, an image of a scene viewed from a virtual point of view, which moves along a virtual point-of-view moving route, in a virtual line-of-sight direction is displayed on a head-up display. Assuming that a next intersection at which to change lane according to a guidance route is the target intersection, a combination of the virtual point of view and virtual line-of-sight direction is gradually changed from a combination in which a scene is viewed from the point of view of the user in the forward direction of the vehicle to a combination for taking a bird's eye view of a geographic range that includes the current position of the vehicle and then to a combination for taking a bird's eye view of a geographic range that includes the target intersection from a point near the target intersection.

Abstract: When an instruction to start voice input is received from the user, a gain controller acquires, from a gain table which defines a correspondence between vehicle speed ranges and gains, a gain corresponding to a vehicle speed range including the vehicle speed of a vehicle detected by a vehicle speed detector, and sets the acquired gain as the gain of an input amplifier that amplifies an input audio signal output by a microphone. As a gain corresponding to each vehicle speed range, the gain table records a gain of the input amplifier corresponding, in an experimentally determined frequency distribution of peak values in the vehicle speed range, to a maximum frequency in the range of magnitude of voice output as an input audio signal by the microphone and to be input to a speech recognition engine as voice having a magnitude within the input range of the speech recognition engine.

Abstract: An error path characteristic model correction control unit determines the deviation of the phase of an actual transfer function from the phase of an error path characteristic model, from a cross correlation between an error signal output from a microphone and a signal in which the error path characteristic model is applied to a noise cancellation sound to be output and a cross correlation between the error signal and a signal in which a transfer function having a phase characteristic deviating by +90 degrees from the phase characteristic of the error path characteristic model is applied to the noise cancellation sound. The error path characteristic model correction control unit then corrects the error path characteristic model so that the determined deviation is reduced to ±90 degrees.
