## Abstract

A trailer vehicle control system has a trailer electronic brake system ECU, which ECU is configured to receive a request, via a CAN bus, from a telematics unit or from a trailer access point. The trailer vehicle control system can verify a status or position of the trailer, in particular using ramp distance control. The trailer vehicle control system can then execute an annoyance feature in response to the request when the control system has determined that the status or position of the trailer meets a defined safe condition.

## Claims

### Claim 1

A trailer vehicle control system, comprising:
a trailer electronic brake system ECU of a trailer, which ECU is configured to receive a request, via a CAN bus, from a telematics unit or from a trailer access point, wherein
the trailer vehicle control system verifies a status or position of the trailer, and
the trailer vehicle control system executes an annoyance feature in response to the request when the trailer electronic brake system has determined that the status or the position of the trailer meets a defined safe condition.

### Claim 2 (depends on 1)

The trailer vehicle control system according to claim 1, wherein
the trailer comprises a ramp distance control RDC system, and
the vehicle control system executes the annoyance feature when the RDC system is active.

### Claim 3 (depends on 1)

The trailer vehicle control system according to claim 1, wherein
the annoyance feature comprises an application of brakes of the trailer for a predetermined time interval by the trailer electronic brake system ECU.

### Claim 4 (depends on 1)

The trailer vehicle control system according to claim 1, wherein
the annoyance feature comprises an application of brakes of the trailer when a trailer position is determined as being within a predefined distance of a dock.

### Claim 5 (depends on 1)

The trailer vehicle control system according to claim 1, wherein
the trailer comprises a suspension, and
the annoyance feature comprises lowering or raising a trailer height.

### Claim 6 (depends on 1)

The trailer vehicle control system according to claim 1, wherein the trailer is lowered to bump stops of the trailer.

### Claim 7 (depends on 1)

The trailer vehicle control system according to claim 1, wherein the trailer is raised to its maximum height.

### Claim 8 (depends on 1)

The trailer vehicle control system according to claim 1, wherein the trailer is disabled using on-board data.

### Claim 9 (depends on 8)

The trailer vehicle control system according to claim 8, wherein the on-board data comprises a tire pressure or an amount of brake lining wear.
