Problems solved by technology

However, if a small signal is amplified with a large amplification rate, the signal-to-noise ratio (Signal to Noise Ratio: SNR) will be reduced and it will be difficult to distinguish the signal from the noise.
Moreover, the amplifier unit in the receiving device of the traditional parking assistance system can be replaced by an amplifier unit applying nonlinear characteristics (Non-linear), but the manufacturing method of the amplifier unit applying nonlinear characteristics is complicated and expensive, and thus There is a defect that the production cost increases

Abstract

The invention provides a receiver and a method of a parking assistant system. The receiver device is characterized in that, a square detector is used to replace a current envelop line detector between an AD conversion part and a comparison part on a parking assistant system receiver using an ultrasonic sensor, so as to improve signal-to-noise ratio, thereby improving accuracy of the ultrasonic sensor detecting an object. The invention also provides a receiving method for the parking assistant system using the device, and the receiving method is characterized in that, storage medium of a predefined lookup table form is used to improve the signal-to-noise ratio.

Description

technical field [0001] The invention relates to a sensor signal receiving device and a receiving method of a parking assist system, in particular to a receiving device and a receiving method using the device for improving the signal-to-noise ratio of the parking assist system. Background technique [0002] Generally, a parking assist system that assists in parking a vehicle has the function of detecting surrounding objects within the allowable distance of the approaching vehicle during parking and providing information. For this purpose, conventional parking assistance systems generally also include the action of measuring distances with ultrasonic sensors. The reception device of the parking assist system using the ultrasonic sensor that measures the distance between the object and the car goes through the following reception signal processing. [0003] figure 1 Figure 10 is the structural diagram of a conventional parking assistance system receiving device. The process ...
