Information conveyance method during automatic driving, and in-vehicle information presentation device

Abstract

The present invention ascertains an action schedule of an automatic driving system when a host vehicle is travelling in an automatic driving mode, and uses an indirect weak expression to convey the action schedule to a driver, at an action schedule presentation start location (P) which has more leeway with respect to a scheduled action location (P) (steps S, S). In the case of an acceleration/deceleration action schedule, an illuminance distribution of the speedometer dial plate, a virtual pointer or the like is used to express the action schedule such that the driver is able to intuitively ascertain the acceleration or deceleration. In the case of a steering action schedule, the steering direction is expressed using a change in illumination near the steering wheel representing the direction of steering or the like is used.
