TORQUE-BASED TRANSMISSION CONTROL METHOD USING HYDRAULIC SENSOR AND AUTOMATIC TRANSMISSION DEVICE CONTROLLED BY SAME

摘要

Disclosed is a torque-based transmission control method using a hydraulic sensor and an automatic transmission device controlled by the same. According to one embodiment of the present invention, a transmission control method (S100) to control gear shift of an automatic transmit device including a transmission controller, an engine controller, and a detection unit comprises: (S110) a first data detection step of using the engine controller to detect an engine speed value, a torque value, and a pressing value of an accelerator pedal; (S120) a step of using the detection unit to detect an input side speed of a turbine, an oil temperature of a transmission, and a hydraulic pressure of a clutch; (S130) using a hydraulic sensor to calculate an actual torque value and using hardware analysis with respect to a physical value of the clutch to calculate a target torque value; and (S140) a feedback control step of calculating a difference value between the actual torque value and the target torque value acquired through the torque value calculation step, and performing current feedback control with respect to a torque value difference. Accordingly, a problem of a conventional technology causing a difference between a target hydraulic pressure and an actual hydraulic pressure output by using a solenoid not to attain the target pressure is able to be removed, and stable and efficient transmission control is received.;COPYRIGHT KIPO 2018
