## Abstract

An ADAS-linked active hood apparatus for always-on operation is provided. The apparatus includes a hinge arm that is connected to a hood of a vehicle, a stationary bracket that is fixed to a vehicle body, and a rotary bracket that rotates about a pivot pin of the stationary bracket. A first link interconnects the rotary bracket and the hinge arm and a spindle is integrally connected to the rotary bracket. A controller receives driving information of the vehicle via an ADAS and adjusts a pop-up height of the hood when a collision is expected based on the received driving information.

## Claims

### Claim 1

An advanced driving assistance system (ADAS)-linked active hood apparatus for always-on operation, comprising:
a hinge arm connected to a hood of a vehicle;
a stationary bracket fixed to a vehicle body;
a rotary bracket configured to rotate about a pivot pin of the stationary bracket;
a first link configured to interconnect the rotary bracket and the hinge arm;
a spindle integrally connected to the rotary bracket; and
a controller configured to receive driving information of the vehicle via an ADAS and to adjust a pop-up height of the hood when a collision is expected based on the received driving information.

### Claim 2 (depends on 1)

The apparatus of claim 1, wherein the controller is configured to set an amount of upward movement of the spindle based on a position of a collision object, a time-to-collision (TTC), a probability of a collision, and the collision object measured by the ADAS when the collision is expected based on the received driving information.

### Claim 3 (depends on 2)

The apparatus of claim 2, wherein the controller is configured to sort the probability of a collision into at least one stage and to set the amount of upward movement of the spindle based on the stage of the probability of a collision.

### Claim 4 (depends on 2)

The apparatus of claim 2, wherein the controller is configured to set the amount of upward movement of the spindle based on a type of the collision object.

### Claim 5 (depends on 1)

The apparatus of claim 1, further comprising:
a pop-up link connected to the spindle to limit the pop-up height of the hood, wherein the pop-up link is configured to rotate the first link.

### Claim 6 (depends on 5)

The apparatus of claim 5, wherein the spindle, the pop-up link, and the rotary bracket are integrally coupled to each other via a ball joint.

### Claim 7 (depends on 1)

The apparatus of claim 1, wherein the rotary bracket, the first link, and the spindle are integrally connected to each other via a ball joint.

### Claim 8 (depends on 1)

The apparatus of claim 1, further comprising:
a second link connected to the rotary bracket and the hinge arm.
