A method for examining the environment of a vehicle by analyzing echo signals generated by reflection of transmitted ultrasonic signals at an object in the environment of the vehicle, wherein in the method - an ultrasonic burst signal with a first number of ultrasonic pulses following each other at a frequency and, timely offset from this ultrasonic burst signal , an ultrasonic burst signal with a second number of ultrasonic pulses following each other at the same or a different frequency are respectively transmitted into the same area of the environment of the vehicle and in the same direction by an ultrasonic transmitter within repeating measuring cycles, the second number of ultrasonic pulses being different from the first number of ultrasonic pulses, - timely offset echo signals are created at an object potentially present in said area of the environment of the vehicle by reflection of the two ultrasonic burst signals , which echo signals are received by an ultrasonic receiver , and - the echo signals of both ultrasonic burst signals are evaluated to determine different parameters of an object potentially present in said area of the environment of the vehicle , - the distance of an object potentially present in said area of the environment of the vehicle from the vehicle being calculated based on the echo signal of the ultrasonic burst signal with the lower number of ultrasonic pulses, and - based on the echo signal of the ultrasonic burst signal with the higher number of ultrasonic pulses, the velocity can be calculated at which the vehicle and an object potentially present in said area of the environment of the vehicle move relative to each other in the direction of transmission of both ultrasonic burst signals or opposite thereto. - an ultrasonic burst signal with a first number of ultrasonic pulses following each other at a frequency and, timely offset from this ultrasonic burst signal , an ultrasonic burst signal with a second number of ultrasonic pulses following each other at the same or a different frequency are respectively transmitted into the same area of the environment of the vehicle and in the same direction by an ultrasonic transmitter within repeating measuring cycles, the second number of ultrasonic pulses being different from the first number of ultrasonic pulses, - timely offset echo signals are created at an object potentially present in said area of the environment of the vehicle by reflection of the two ultrasonic burst signals , which echo signals are received by an ultrasonic receiver , and - the echo signals of both ultrasonic burst signals are evaluated to determine different parameters of an object potentially present in said area of the environment of the vehicle , - the distance of an object potentially present in said area of the environment of the vehicle from the vehicle being calculated based on the echo signal of the ultrasonic burst signal with the lower number of ultrasonic pulses, and - based on the echo signal of the ultrasonic burst signal with the higher number of ultrasonic pulses, the velocity can be calculated at which the vehicle and an object potentially present in said area of the environment of the vehicle move relative to each other in the direction of transmission of both ultrasonic burst signals or opposite thereto. <EOS>
