A driver assistance ECU initiates monitoring to determine whether a driver has performed a preparatory action, based on a motion sensor output signal, in response to the appearance of an object with a time to collision (TTC) less than a predetermined starting value. If the preparatory action is successfully detected within a specified time period (from when the TTC falls below the starting value to when the TTC reaches the starting value), the driver assistance ECU sets the warning tone output time to a later time than the default. If the preparatory action is not successfully detected within the specified time period, the driver assistance ECU sets the warning tone output time to the default time or to a time earlier than the default.

To provide a warning sound control device that facilitates recognition of the distance to approaching objects.SOLUTION: A warning sound control device (10) detects an object (30) approaching a moving body (1), determines the direction in which a sound image of the warning sound is localized based on the direction of the object (30) with respect to the moving body (1), and determines the trajectory of the sound image of the warning sound based on the distance from the moving body (1) to the object (30).

A context-aware voice guidance method is provided that interacts with other voice services of a user device. The voice guidance does not provide audible guidance while the user is making a verbal request to any of the voice-activated services. Instead, the voice guidance transcribes its output on the screen while the verbal requests from the user are received. In some embodiments, the voice guidance only provides a short warning sound to get the user's attention while the user is speaking on a phone call or another voice-activated service is providing audible response to the user's inquires. The voice guidance in some embodiments distinguishes between music that can be ducked and spoken words, for example from an audiobook, that the user wants to pause instead of being skipped. The voice guidance ducks music but pauses spoken words of an audio book in order to provide voice guidance to the user.
