  • Method and system of urea solution level measurement adjustment, display and heater operation
    Patent number: 10968806
    Abstract: A method of adjusting and displaying urea solution level measurement value may include measuring urea solution concentration injected into a urea solution tank by a urea solution quality sensor, determining whether unclean urea solution is injected into the urea solution tank by the measured urea solution concentration, adjusting urea solution level value according to the urea solution concentration when the unclean urea solution is injected into the urea solution tank, comparing urea solution level measurement value with reference urea solution level measurement value, and lighting up a warning lamp when the urea solution level measurement value is lower than the reference urea solution level measurement value.
    Type: Grant
    Filed: April 12, 2019
    Date of Patent: April 6, 2021
    Assignees: Hyundai Motor Company, Kia Motors Corporation
