A control method for shifting in a manual transmission vehicle may include sensing tip-out while the vehicle travels; operating a tip-out torque filter when the tip-out is sensed; determining whether a switch of a clutch of the vehicle is turned on; stopping fuel injection by stopping the tip-out torque filter when the switch of the clutch is turned on, and reducing rotation speed of an engine by controlling a throttle flap of the vehicle.

Control method for shifting in manual transmission vehicle

An idle throttle valve control method of a diesel vehicle, may include a first step of determining whether an idle entry condition of the vehicle may be satisfied, a second step of controlling a throttle valve based on an air amount map and controlling an exhaust gas recirculation (EGR) valve based on an EGR map, when the first step may be satisfied, a third step of determining whether an idle release condition may be satisfied during the second step, and a fourth step of determining whether an EGR return condition may be satisfied, when the idle release condition may be satisfied in the third step.

Control method of diesel vehicle

A method for controlling a damper clutch may include determining whether the damper clutch is in a slip or lock-up state in a driving state of a vehicle, determining whether a condition of the vehicle is within a predetermined resonant range, determining whether a torque of the vehicle is within a predetermined resonant torque range, detecting a subharmonic vibration when the damper clutch is in the slip or lock-up state, the condition of the vehicle is within the predetermined resonant range, and the torque of the vehicle is within the predetermined resonant torque range, and controlling the damper clutch to slip or be open when the subharmonic vibration is larger than a predetermined value.

Method for controlling a damper clutch

A throttle valve device including a throttle valve control logic may include an electronic controller that determines whether a driving state of a vehicle is an idle-driving state from electronic signals supplied from sensors, a desired air amount map unit that is electrically connected with the electronic controller and where a desired amount of air according to RPM of an engine and an amount of injected fuel for idle-driving are set; and a governor for controlling an EGR valve and a governor for controlling a throttle valve that are electrically connected with the electronic controller and the desired air amount map unit and control the driving of the EGR valve and the throttle valve, respectively, such that the desired amount of air output in accordance with the RPM of the engine of the vehicle and an amount of the injected fuel is supplied to the engine in the idle-driving.
