## Abstract

A method of mitigating false warning on a vehicle having at least one side radar sensor, a steering wheel and a steering angle sensor comprises the at least one side radar sensor not detecting an object. The steering angle sensor detects that the steering wheel has moved such that the vehicle and the trailer are out of line. Warning arising from the at least one side radar sensor is suspended.

## Claims

### Claim 1

A method of mitigating false warning on a vehicle having a trailer, at least one side radar sensor, a steering wheel, at least one sensor on at least one of a hitch and a kingpin, and a steering angle sensor, the method comprising the steps of:
the at least one side radar sensor not detecting an object independent of the vehicle and the trailer;
the steering angle sensor detecting that the steering wheel has moved such that the vehicle and the trailer are out of line;
suspending warning arising from the at least one side radar sensor; and
lifting suspending warning arising from the at least one side radar sensor when the at least one sensor on at least one of the hitch and the kingpin and the steering angle sensor indicate that the vehicle and trailer are in line.

### Claim 2

A method of mitigating false warning on a vehicle having a trailer, at least one side radar sensor, a steering wheel, at least one sensor on at least one of a hitch and a kingpin, and a steering angle sensor, the method comprising the steps of:
the at least one side radar sensor not detecting an object independent of the vehicle and the trailer;
the steering angle sensor monitoring movement of the steering wheel;
suspending warning arising from the at least one radar sensor as the steering angle sensor determines that the angle between the vehicle and the trailer has decreased such that the area between the vehicle and the trailer is insufficient to accommodate an object that can damage the vehicle or trailer; and
lifting suspending warning arising from the at least one side radar sensor when the at least one sensor on at least one of the hitch and the kingpin and the steering angle sensor indicate that the space between vehicle and the trailer has increased to be able to accommodate a damaging object.
