Method and device for determining the position of an object in relation to a vehicle, in particular a motor vehicle, for use in a driver assistance system of the vehicle

A method for determining a position of an object in relation to a motor vehicle, for use in a driver assistance system of the motor vehicle, comprising:

• transmitting, by a first ultrasound sensor situated on the vehicle, a first ultrasound pulse including multiple predefined transmission frequencies which result in a variation of directional characteristics of the first ultrasound sensor;
• receiving, by one of the first ultrasound sensor or a second ultrasound sensor situated on the vehicle, the first ultrasound pulse reflected by the object as a first echo pulse;
• determining a frequency spectrum of the first echo pulse;
• and
• determining a first absolute value of a relative offset angle of the object as a function of the frequency spectrum of the first echo pulse and the directional characteristics of the first ultrasound sensor.
