An operation authority management apparatus manages switching between automatic operation and manual operation of a plurality of actuators (a steering actuator, an accelerator actuator, and a brake actuator) of a subject vehicle. In the operation authority management apparatus, a subject vehicle behavior prediction unit predicts a behavior of the subject vehicle. A determination unit determines, for each individual actuator, whether or not to permit switching of the actuator during the automatic operation to the manual operation on the basis of the behavior of the subject vehicle predicted by the subject vehicle behavior prediction unit. A notification unit notifies a driver of the subject vehicle of a determination result made by the determination unit.

An automatic driving control plan creator creates a plan of an automatic driving section where a subject vehicle is automatically driven, and a plan of a driving switching preparation section for switching the subject vehicle from automatic driving to manual driving. A driving load calculator predicts, for each point of the driving switching preparation section, a driving load applied to a driver when the driver manually drives the subject vehicle. A driving switching permission determiner extracts, from the driving switching preparation section, a switching-inhibited section that is a section where switching from automatic driving to manual driving is not permitted, on the basis of the predicted driving load at each point. A driving switching preparation section compensator changes a start point of the driving switching preparation section so as to lengthen the driving switching preparation section in accordance with the length of the switching-inhibited section.

An automatic driving control plan creation unit creates a plan of an automatic driving section in which a subject vehicle is automatically driven, and a plan of a driving switching preparation section for switching the subject vehicle from automatic driving to manual driving. For each point in the driving switching preparation section, a driving load calculation unit calculates a driving load applied to a driver when the driver manually drives the subject vehicle. A driving switching permission determination unit permits switching of the subject vehicle from automatic driving to manual driving at a point where the driving load is smaller than a predetermined threshold value, and does not permit switching of the subject vehicle from automatic driving to manual driving at a point where the driving load is equal to or larger than the threshold value. A permission standard relaxation unit makes the driving load difficult to exceed the threshold value.

An object of the present invention is to implement, at a low hardware cost, a device that changes an autonomous driving control parameter whose step size is variably set.
