摘要： A method and apparatus for controlling part load mode engine torque are provided. The method includes setting a limitation of part load mode engine torque based on a current traveling environment and calculating a first engine torque variation in the basis of state information of a battery. When the first engine torque variation is calculated, a second engine torque variation is calculated based on a measured engine error amount. The limitation of part load mode engine torque is compensated based on the calculated first and second engine torque variations.

摘要： A clutch control method for a hybrid vehicle with a DCT is provided. The method includes determining an energy-saving possible period based on a selection state of shifting ranges, operation states of an accelerator pedal and a brake pedal, and the gradient of a road on which the vehicle is driven. An operation current is set for maintaining a clutch, which is configured to engage the first gear, engaged as 0 A in response to determining that a current state of the vehicle is in the energy-saving possible period.

摘要： A hybrid vehicle includes an electric motor, an engine including an exhaust gas purifying unit, and an engine clutch disposed between the electric motor and the engine. A method of controlling the hybrid vehicle includes determining a driving environment condition including a first condition related to at least a driving load when a request for operating the exhaust gas purifying unit is received, determining a state of the engine clutch and an operation condition of the exhaust gas purifying unit when the exhaust gas purifying means operates according to the result of determining the driving environment condition, and operating the exhaust gas purifying unit while maintaining the determined state of the engine clutch when the driving environment condition is satisfied.

摘要： A method of determining a vehicle driving pattern includes: acquiring current driving information to determine the vehicle driving pattern of a driver while a vehicle is driven; determining the vehicle driving pattern of a driving condition with which the acquired current driving information is satisfied from a plurality of vehicle driving patterns divided based on the driving condition; determining whether the determined vehicle driving pattern satisfies an entry condition of an aggressive driving pattern based on a driving load of the vehicle and a value of an accelerator pedal sensor according to a driver's operation of an accelerator pedal, while the acquired current driving information satisfies the driving condition of the determined vehicle driving pattern; and determining that the current vehicle driving pattern is the aggressive driving pattern when the entry condition of the aggressive driving pattern is satisfied.

摘要： Disclosed is a control method that improves response delay by reducing the time taken to determine the engagement type of an engine clutch, by making it possible to determine quickly the engagement type by a slip process under a disadvantageous operating conditions for the synchronization process such as traveling up a slope, traveling in a congestion section, or traveling under to or close to a discharging limit, and can improve fuel efficiency and battery SOC management due to unnecessarily using electric energy when engagement cannot be achieved by the synchronization process.
