Publication number: US20220169171A1
Application number: 17/554,500

Abstract:
A vehicle system device is provided. The vehicle system device includes a headlamp, a storage storing information about a height where the headlamp is mounted and a left and right distance, and a controller. The controller includes a road surface information generator that generates road surface information corresponding to a sensor signal, a coordinate converter that obtains location coordinates of the road surface information and converts the location coordinates into angle coordinates based on the information stored in the storage, and a headlamp controller that controls the headlamp to emit the road surface information based on the angle coordinates. In addition, various embodiments recognized through the specification are possible.

Application number: 17/553,247

Abstract:
Provided is a system for controlling a detecting distance of an ultrasonic sensor based on ground recognition. The system includes: an ultrasonic sensor provided in a vehicle and configured to, when driven, recognize an object in front of or behind the vehicle; an image capturing unit configured to capture an image of a detection area of the ultrasonic sensor; a ground type recognizer configured to recognize a ground type corresponding to the detecting area of the ultrasonic sensor using the image acquired through the image capturing unit; and a sensing threshold changer configured to, when a travelling speed of the vehicle satisfies a preset condition, change a sensing threshold of the ultrasonic sensor according to the recognized ground type.

Application number: 17/550,446

Abstract:
The present invention relates to an apparatus and method capable of performing immediate impedance matching according to changes of a distance and positions between TX/RX coils. The present invention includes: an impedance adjustment unit including a voltage-controlled variable capacitance device; a power detector configured to detect a reflection signal which enters the transmitter or receiver when there is no impedance matching to measure a magnitude of the reflection signal and convert the reflection signal into a DC signal; a multiplier configured to multiply the DC signal with a periodic signal; an integrator configured to accumulate and add a signal in which the DC signal and the periodic signal are multiplied; and a voltage summer configured to sum a signal output from the integrator with a reference voltage to calculate a capacitance control voltage to be applied to the voltage-controlled variable capacitance device.
