- an indicator mounted on the vehicle configured to present information indicating a direction; and
a control unit configured to control presentation of the information by the indicator, whereinthe control unit includesa vehicle information acquiring unit configured to acquire a current position of the vehicle and a reference direction of the vehicle;
a target specifying unit configured to specify a target to be presented to an occupant of the vehicle;
a target information acquiring unit configured to acquire a target position, the target position being a position where the target exists;
a target angle calculating unit configured to calculate a target angle indicating a target direction against the reference direction based on the target position, the current position and the reference direction, the target direction being a direction in which the target exists; and
a presentation command generating unit configured to generate a presentation command based on the calculated target angle, the indicator being to present information indicating the target direction according to the presentation command, whereinthe vehicle information acquiring unit is further configured to acquire a velocity of the vehicle in addition to the current position and the reference direction, andthe target angle calculating unit is further configured toestimate a position of the vehicle after a predefined time and a reference direction of the vehicle after the predefined time based on the current position, the reference direction and the velocity, andcalculate a target angle after the predefined time based on the estimated position, the estimated reference direction and the target position.

Abstract
An information presentation apparatus for a vehicle includes an indicator mounted on the vehicle for indicating a target direction and a control unit for controlling the indicator. The control unit includes a function for acquiring a current position of the vehicle and a reference direction of the vehicle, a function for specifying a target and acquiring a target position, a function for calculating a target angle that indicates a target direction against the reference direction based on the target position, the current position and the reference direction, and a function for generating a presentation command based on the calculated target angle so as to indicate the target direction by the indicator. According to the apparatus, information for specifying the target position can be provided.
