Abstract: The present invention a cruise control apparatus for a vehicle, which provides positive vehicle speed control on very little changes in a vehicle speed through back pressure control and prevents heterogeneity from occurring in a transition area of staged control. The apparatus comprises a map based back pressure determining unit which determines a target back pressure for vehicle speed control according to the vehicle speed and load if the situation is a speed reduction control condition during cruise driving; a back pressure adjusting unit which regulates back pressure by operating a back pressure regulating valve mounted on an exhaust manifold, in order to follow the target back pressure; a calculator which extracts a deviation by calculating the real back pressure adjusted by the back pressure adjusting unit and the target back pressure determined by the map based back pressure determining unit; and a PID controller which compensates for the back pressure deviation provided by the calculator with proportional-integral-derivative (PID) control, and follows the target vehicle speed by controlling the opening and closing amount of the back pressure regulating valve through the back pressure adjusting unit.

Abstract: PURPOSE: A method of reducing a gear shift shock is provided to apply provisionally hydraulic press in forward clutch so as to make the press work as a drag torque at output shaft of transmission, thereby reducing a shift shock. CONSTITUTION: A multistage transmission recognizes the stopper information of a vehicle and senses the shifting of the shift lever. The multistage transmission provisionally applies hydraulic press in forward clutch like a D(drive) or N(neutral) at the moment it senses a shifting to R(rear) as to use the forward output torque as a drag torque to backward output torque, thereby resolving the gear backlash smoothly.
