Patent number: 11918365Abstract: An electrocardiogram (ECG) measurement device for a vehicle is provided. The ECG measurement device includes an impedance compensator that corresponds to an electrode in contact with a body of a driver and configured to compensate an impedance of each of electrode signals received from the electrode. An electrode selector sequentially selects the electrode signals in response to receiving the electrode signals from the electrode. A differential amplifier differentially amplifies the electrode signals. In particular, each electrode signal has the compensated impedance. Additionally, a signal quality evaluator evaluates quality of an ECG signal output from the differential amplifier and a compensation controller then adjusts an impedance compensation value of each of the impedance compensators as a result of evaluating the quality of the ECG signal.Type: GrantFiled: November 15, 2021Date of Patent: March 5, 2024Assignees: Hyundai Motor Company, Kia CorporationInventors: Yoon Jong Choi, Hyun Wook Jun, Yeong Joon Gil, Min Yong Shin, Soo Hwan Kim
