Application of Ultrasonic Radar in Automobile Parking System and Market Competition Landscape

Ultrasonic radar plays an important role in car parking systems. It measures the distance between the car and surrounding obstacles by emitting and receiving ultrasonic waves. This sensor is particularly suitable for functions such as parking assistance warning and car blind spot collision warning. At present, there are four main ultrasonic radar technical solutions on the market: analog, four-wire digital, two-wire digital and three-wire active digital. Among them, analog technical solutions occupy the main market due to their low cost. However, with the development of the intelligent trend, digital technical solutions may become more popular. In terms of market competition, companies such as Bosch, Murata of Japan and Nisela of Japan occupy a dominant position.
