Description

Apparatus and Method of Control for Vehicle One embodiment of the present invention relates to a control method and device for a vehicle, and specifically to a method for setting a signal processing mode according to the surrounding environment of an ultrasonic sensor for a vehicle. When a vehicle uses sensors to detect objects, false alarms caused by external noise rather than objects can be prevented by processing the received sensor signals. Sources of external noise may include signals transmitted by other vehicles or noise sources from the surrounding environment, such as air conditioners and horns. Contradictory functions must be provided so that objects/obstacles are detected, but no warning is given if they are not present. However, if signal processing is performed to further suppress noise, object detection performance may degrade, potentially leading to false alarms, and if object detection performance is enhanced, noise suppression performance may degrade. To solve these problems, we propose a method for setting the signal processing mode of a vehicle sensor according to the surrounding environment.
