  • Patent number: 11125128
    Abstract: A method of controlling regeneration of a particulate filter which traps particulate matter contained in an exhaust gas may include: raising, by a controller, a temperature of the exhaust gas to regenerate the particulate filter by burning the trapped particulate matter when an amount of the particulate matter trapped in the particulate filter is greater than or equal to a predetermined amount. Raising the temperature of the exhaust gas may include: raising the temperature of the exhaust gas based on a first temperature difference compensation, and raising the temperature of the exhaust gas based on a second temperature difference compensation. In particular, the first and second temperature difference compensations are calculated based on a target temperature of the exhaust gas at an upstream of the particulate filter and an actual temperature of the exhaust gas at the upstream of the particulate filter.

  • Patent number: 10947916
    Abstract: A control method of a vehicle having an exhaust gas recirculation (EGR) system includes efficiently controlling a temperature of recirculated exhaust gas and, even when the temperature of recirculated exhaust gas excessively increases, damage to hardware, such as an intake manifold or parts of the exhaust gas recirculation system can be prevented. The control method includes: detecting the temperature of exhaust gas recirculated to an engine intake system by the EGR system; entering into a protection mode so as to control the temperature of the recirculated exhaust gas; determining a correction value such that the controller controls the temperature of the recirculated exhaust gas; and correcting an engine control value by using the determined correction value and controlling an engine according to the corrected engine control value.

  • Patent number: 10697385
    Abstract: An engine control method for a vehicle may include a temperature securing determination step of determining, by a controller, whether an exhaust gas temperature before a turbine of a turbocharger is normally secured; a basic determination step of, when the exhaust gas temperature before the turbine is normally secured, obtaining, by the controller, a first compensation torque according to a current state of the vehicle from a first compensation torque map according to the exhaust gas temperature before the turbine, an engine operation mode, engine speed, and atmospheric pressure; and an engine control step of, when the exhaust gas temperature before the turbine is normally secured, determining, by the controller, a final compensation torque on the basis of the first compensation torque and controlling engine torque at a value which is obtained by subtracting the final compensation torque from engine full-load torque.
