## Abstract

A vehicle driving assist apparatus suspends executing a following moving control and starts executing a process of measuring an elapsing time which elapses since suspending executing the following moving control when a control suspending condition that a driver of an own vehicle carries out an accelerating operation of accelerating the own vehicle in order to pass the next lane preceding vehicle, becomes satisfied, resets the elapsing time and start measuring the elapsing time which elapses since resetting the elapsing time when the own vehicle has passed the next lane preceding vehicle before the elapsing time reaches a predetermined time, and restarts executing the following moving control when a control restarting condition that the elapsing time reaches the predetermined time, is satisfied.

## Claims

### Claim 1

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.

### Claim 2 (depends on 1)

The vehicle driving assist apparatus as set forth in claim 1, wherein the control suspending condition includes a condition that (i) the own vehicle moves in a cruising lane, and (ii) the next lane preceding vehicle moves in a passing lane.

### Claim 3 (depends on 1)

The vehicle driving assist apparatus as set forth in claim 1, wherein the control suspending condition includes a condition that a traffic congestion of the next lane preceding vehicles occurs.

### Claim 4 (depends on 1)

The vehicle driving assist apparatus as set forth in claim 1, wherein the control restarting condition includes a condition that the accelerating operation is not carried out.

### Claim 5 (depends on 1)

The vehicle driving assist apparatus as set forth in claim 1, wherein the electronic control unit is configured to:
execute a process of detecting an own lane preceding vehicle which moves ahead of the own vehicle in the lane in which the own vehicle moves when the electronic control unit is executing the following moving control; and
execute the following moving control to autonomously control the moving speed of the own vehicle so as to maintain a distance between the own lane preceding vehicle and the own vehicle at a predetermined own lane inter-vehicle distance when (i) there is not the next lane preceding vehicle, and (ii) there is the own lane preceding vehicle.

### Claim 6 (depends on 1)

The vehicle driving assist apparatus as set forth in claim 1, wherein the electronic control unit is configured to:
execute a process of detecting an own lane preceding vehicle which moves ahead of the own vehicle in the lane in which the own vehicle moves when the electronic control unit is executing the following moving control;
execute the following moving control to autonomously accelerate the own vehicle when (i) there is the next lane preceding vehicle, (ii) there is the own lane preceding vehicle, (iii) a distance between the own lane preceding vehicle and the own vehicle is longer than a predetermined own lane inter-vehicle distance, and (iv) the distance between the next lane preceding vehicle and the own vehicle is longer than the predetermined next lane inter-vehicle distance; and
execute the following moving control to autonomously decelerate the own vehicle when (i) there is the next lane preceding vehicle, (ii) there is the own lane preceding vehicle, and (iii) the distance between the own lane preceding vehicle and the own vehicle is shorter than the predetermined own lane inter-vehicle distance, or (iv) the distance between the next lane preceding vehicle and the own vehicle is shorter than the predetermined next lane inter-vehicle distance.

### Claim 7 (depends on 1)

The vehicle driving assist apparatus as set forth in claim 1, wherein the control suspending condition includes a condition that the own vehicle moves on an express highway.
