The disclosure relates to an apparatus configured to reduce a speed of a motor vehicle to a predetermined value at a predetermined position. The apparatus includes a position-capture device configured to establish the predetermined position by evaluating map data relating to a planned route of the motor vehicle, and a target-setting device for establishing the predetermined value at the predetermined position.
Method and apparatus for providing a map display based on velocity information
An approach is provided for presenting comprehensible representation of travel segments based, at least in part, on velocity information. The approach involves processing and/or facilitating a processing of traffic information, velocity information, or a combination thereof for one or more travel segments, characteristic information for one or more vehicles, or a combination thereof to determine the one or more travel segments within a velocity threshold level. The approach also involves causing, at least in part, a filtering of the one or more travel segments based, at least in part, on the velocity threshold level. The approach further involves causing, at least in part, a presentation of at least one mapping user interface depicting one or more representations for the one or more travel segments within the velocity threshold level.

Corner-Based Longitudinal Speed Estimation
A system and method for computationally estimating a directional velocity of a vehicle in real time under different configurations and road conditions for use in vehicle antilock braking, adaptive cruise control, and traction and stability control by correcting measured accelerations with respect to the estimated road angles. A time window is used to provide reliable mapped acceleration for the transient regions and maneuvers on gravel surfaces with high fluctuations in the acceleration measurement. Longitudinal and lateral accelerations are mapped from the vehicle's CG into the tire coordinates using the vehicle's geometry, lateral velocity, yaw rate, and the steering wheel angle to generate system matrices of the combined kinematic-force estimation structure.
