Patent ID: 8005602

Claim:
A vehicle speed control device including a speed control section, the vehicle speed control device for controlling a speed of a vehicle within a control-executed zone by computing a target speed of the vehicle based on map information and a current location of the vehicle and by supplying the target speed to the speed control section, the vehicle speed control device comprising: a current location error estimation section for extracting area attribute information from the map information, for producing a location error probability distribution of the vehicle based on the area attribute information, and for outputting the produced location error probability distribution as a target speed correction instruction, wherein the area attribute information indicates an attribute of the current location or of the control-executed zone; a human sensitivity model memory section for storing preset data comprising an acceleration or a gradient of an acceleration which is predetermined based on a distance between a destination and a speed change start point of a target speed; a target speed calculation section for receiving the target speed correction instruction from the current location error estimation section, accessing the preset data stored in the human sensitivity model section, computing target speed values at nodes over the distance in such a way that the target speed values create a continuous curve, calculating a target speed error based on the location error probability distribution, and updating the target speed values in the continuous curve based on the target speed error; and a speed control section for sensing a speed of a vehicle, and for controlling a driving torque of the vehicle so that the sensed speed traces the continuous curve composed of the target speed values.
