Vehicle speed controller

Abstract

Abstract PURPOSE:To enable quick reset to a control target speed by switching the speed change stage to the low speed side while resetting an integrated deviation of vehicle speed upon decision that the control target speed can not be maintained. CONSTITUTION:A vehicle speed controller comprises a deviation integrating means 5 for integrating the deviation between a control target speed set by a target vehicle speed setting means 3 and an actual vehicle speed detected through a vehicle speed sensor while a control circuit 7 for providing a drive signal corresponding with the integrated deviation to a throttle actuator 1 is provided. Here, the control circuit 7 is provided with means 11 for deciding such condition as the control target speed can not be maintained at least on the basis of the control target speed and the actual vehicle speed. Upon reception of a signal informing that the control target speed can not be maintained, a shift-down command is provided from a speed change command means 13 to an automatic speed change controller 9 while a reset command signal is provided from a reset command means 15 to the deviation integrating means 5.
