Vehicle driving assist apparatus

A vehicle driving assist apparatus, comprising an electronic control unit which (i) executes a following moving control of executing a process of detecting a next lane preceding vehicle which moves ahead of an own vehicle in a lane next to a lane in which the own vehicle moves, and (ii) autonomously controlling a moving speed of the own vehicle so as to maintain a distance between the next lane preceding vehicle and the own vehicle at a predetermined next lane inter-vehicle distance,

• wherein the electronic control unit is configured to:
• suspend executing the following moving control and starts executing a process of measuring an elapsing time which elapses since the electronic control unit suspends executing the following moving control when a control suspending condition that a driver of the own vehicle carries out an accelerating operation of accelerating the own vehicle in order to pass the next lane preceding vehicle, becomes satisfied;
• reset the elapsing time and start measuring the elapsing time which elapses since the electronic control unit resets the elapsing time when the own vehicle has passed the next lane preceding vehicle before the elapsing time reaches a predetermined time;
• and
• restart executing the following moving control when a control restarting condition that the elapsing time reaches the predetermined time, is satisfied.
