An apparatus for controlling a mild hybrid vehicle includes an engine including a plurality of combustion chambers for generating driving torque by burning fuel, at least one intake valve and at least one exhaust valve for opening and closing each of the combustion chambers, an MHSG (mild hybrid starter and generator) for assisting the driving torque of the engine and selectively being operated as a generator, a VVA (variable valve apparatus) including an oil control valve that changes a direction of a path for flowing engine oil in order to adjust opening timing, lift, and duration of the intake valve and the exhaust valve, and a controller operating the MHSG to assist the engine torque when the oil control valve is faulty.

Apparatus for controlling mild hybrid vehicle and method of using the mild hybrid vehicle

A method and an apparatus for controlling a mild hybrid electric vehicle are provided. The method includes detecting data for operating the vehicle and determining a target torque of an engine based on the detected data. Additionally, the method includes determining whether an operating condition of a limiting logic of a combustion torque of the engine is satisfied based on a temperature of coolant of the engine and operating the limiting logic when the operating condition of the limiting logic is satisfied. A first available combustion torque of the engine is determined based on a speed of the engine and the temperature of the coolant when the limiting logic is operated and a target torque of a MHSG is determined based on the target torque of the engine and the first available combustion torque of the engine. The MHSG is then operated to generate the target torque of the MHSG.

Method and apparatus for controlling mild hybrid electric vehicle

A method for controlling a mild hybrid electric vehicle includes steps of: detecting data regarding the mild hybrid electric vehicle; determining a target torque of an engine according to the detected data; determining whether knocking of the engine occurs according to the detected data; determining a retardation amount of an ignition timing when it is determined that the knocking occurs; comparing the retardation amount of the ignition timing with a value; determining a loss amount of a combustion torque of the engine according to the retardation amount of the ignition timing when the retardation amount of the ignition timing is equal to or greater than the value; determining a target torque of a mild hybrid starter & generator (MHSG) according to the target torque of the engine and the loss amount of the combustion torque of the engine; and operating the MHSG to generate the target torque of the MHSG.

A removing poison apparatus of a lambda sensor includes: a lambda sensor detecting an oxygen concentration included in an exhaust gas; and a control unit differentiating a heating temperature and a heating time to remove poison of the lambda sensor depending on a lambda signal output from the lambda sensor in an overrun condition of the engine. By heating the lambda sensor depending on the magnitude of the lambda signal output from the lambda sensor, the lambda sensor may be inhibited from being degraded by combusting the material poisoned to the electrode of the lambda sensor and the failure of the lambda sensor may be correctly determined.

A vehicle update system for updating a vehicle's ROM data is provided. More specifically, a telematics unit is configured to receive new ROM data transmitted from a telematics server. An electronic control unit (ECU) is configured first check to determine whether certain update conditions are satisfied and when they are satisfied, update the old ROM data to the new ROM data using at least one of a main battery and an auxiliary battery. More specifically, the update conditions are that the charged state and the voltage level for at least one of the main battery and the auxiliary battery is greater than a certain level, the vehicle is stopped or parked, and the controller area network (CAN) communication state of the vehicle is normal.

Vehicle upgrade system and method thereof

A system and method for controlling engine shutoff at vehicle ignition key-off. An ignition module performs ignition in the engine's cylinders according to a predetermined ignition sequence. An engine module detects the cylinder in which ignition currently occurs. An engine control module controls the engine to stop operating only after a predetermined condition is satisfied after key-off. The predetermined condition may be that the cylinder in which ignition currently occurs is a preselected cylinder, such as the cylinder closest to a flywheel. The method determines whether an ignition key is turned off, detects the cylinder in which ignition currently occurs if the ignition key is turned off, determines whether the cylinder in which ignition currently occurs is a preselected cylinder, and controls the engine to stop only if the cylinder in which ignition currently occurs is the preselected cylinder. The preselected cylinder may be closest to a flywheel.

Vibration reducing system at key-off and method thereof

The method for controlling an idle stop-and-go system is based on one or more engine control modes, including a starting mode wherein an engine control unit (ECU) starts an engine by an engine stop release signal received from a starter/generator control unit (SCU), a normal mode for normally operating the engine, and an after-run mode wherein the ECU stops the engine based on an engine stop signal received from the SCU. Initially, it is determined whether a present engine control mode is the normal mode. Thereafter, it is determined whether an engine stop signal is received from the SCU. The engine control mode is then changed to the after-run mode whern the present engine control mode is the normal mode and an engine stop signal is received from the SCU. Finally, the engine warning lamp is blocked from illuminating.

Method for controlling idle stop-and-go system

A system and method for controlling an idle stop-and-go in which an engine control mode is determined according to states and conditions of an engine, so that load calculation of the engine contact unit can be reduced and the engine and the integrated starter generator can be stably controlled.
