Abstract: A system for controlling torque for a hybrid vehicle includes a power source having an engine and a motor. An engine clutch is provided between the engine and the motor. A driving information detector detects demand torque for driving. A traction controller controls oil pressure supplied into a brake to prevent a wheel slip and request torque reduction control from a vehicle controller when the wheel slip is detected. A vehicle controller controls engagement of the engine clutch for driving in a hybrid electric vehicle (HEV) mode, wherein the vehicle controller determines output torques of the engine and the motor to perform torque reduction control according to the torque reduction control, and when the request for the torque reduction control is released, the vehicle controller sets a gradient for torque restoration of the engine and the motor and applies the gradient to follow the demand torque for driving.

Abstract: An offset correction method for an automobile oil pressure sensor determines whether or not an engine start signal is applied. An offset value of the oil pressure sensor installed on an oil pressure line connected to an oil pump is detected within a first preset period after the start signal is applied. An output value of the oil pressure sensor is corrected after the offset value is detected.

Abstract: A method and system for changing a running mode when a battery discharge of a hybrid vehicle is limited include detecting each state of the drive motor and the battery, determining whether a need for a change to a running mode in which an operation of the engine is requested when the drive motor operates and the battery discharge is limited. A starting motor is operated first with an available power of the battery when the change to the running mode is requested. The engine is controlled so that the starting motor may perform a charging operation, for synchronization of an engine clutch, and for driving the drive motor with available power of the battery when the engine has been started by the starting motor.
