Abstract
A method for adjusting a detection area of at least one ultrasonic sensor array of a vehicle using a controller. Measurement data are received and a direction of travel is ascertained. Control signals for controlling at least two transducer elements of at least one ultrasonic sensor array are generated. A phase shift between the ultrasonic waves transmitted by the transducer elements and/or a phase shift between the ultrasonic waves received by the transducer elements is set using the control signals, which phase shift is adjusted to the direction of travel of the vehicle. A controller, a computer program, and a machine-readable storage medium are also described.

The method for adjusting a detection area of at least one ultrasonic sensor array of a vehicle using a controller, comprising the following steps:
- receiving measurement data are received, and ascertaining based on the measurement data, a direction of travel;
- generating control signals for controlling at least two transducer elements of the at least one ultrasonic sensor array;
- and
- setting, using the control signals, a phase shift between ultrasonic waves transmitted by the transducer elements and/or a phase shift between ultrasonic waves received by the transducer elements, the phase shift being adjusted based on the direction of travel of the vehicle.
A controller configured to adjust a detection area of at least one ultrasonic sensor array of a vehicle, the controller configured to:
- receive measurement data are received, and ascertaining based on the measurement data, a direction of travel;
- generate control signals for controlling at least two transducer elements of the at least one ultrasonic sensor array;
- and
- set, using the control signals, a phase shift between ultrasonic waves transmitted by the transducer elements and/or a phase shift between ultrasonic waves received by the transducer elements, the phase shift being adjusted based on the direction of travel of the vehicle.
A non-transitory machine-readable storage medium on which is stored a computer program for adjusting a detection area of at least one ultrasonic sensor array of a vehicle using a controller, the computer program, when executed by a computer, causing the computer to perform the following steps:
- receiving measurement data are received, and ascertaining based on the measurement data, a direction of travel;
- generating control signals for controlling at least two transducer elements of the at least one ultrasonic sensor array;
- and
- setting, using the control signals, a phase shift between ultrasonic waves transmitted by the transducer elements and/or a phase shift between ultrasonic waves received by the transducer elements, the phase shift being adjusted based on the direction of travel of the vehicle.
