1. A vehicle controller comprising:
an engine controller configured to perform, upon satisfaction of a predetermined stop condition, an idling stop control that stops driving of an engine serving as a drive power source of an own vehicle, and to perform, upon satisfaction of a predetermined restart condition, an engine restart control;
a hill descent controller configured to perform, when the own vehicle is traveling on a downhill road and a deceleration control request according to a hill descent control occurs, a deceleration control based on a target vehicle speed set in advance, irrespective of brake operations by a driver of the own vehicle; and
an information acquisition part configured to acquire progress status information related to the engine restart control and including information on initiation and completion of the engine restart control,
wherein the progress status information includes a start time point at which the engine restart control has started, and
wherein the engine controller and the hill descent controller are further configured such that, when an engine restart request according to the idling stop control and the deceleration control request according to the hill descent control occur in a temporally overlapping manner, while the engine controller performs the engine restart control in a prioritized manner, the hill descent controller allows performing the deceleration control based on the target vehicle speed when a predetermined time has elapsed from the start time point even when the engine has not transitioned to a complete explosion state, the predetermined time defined as a complete explosion time up to which it is estimated that the engine has transitioned to the complete explosion state.
