AVSS09-Advanced Vehicle Lateral Control (Service Package*)

Description

This service package automates the steering control on board the vehicle. It utilizes safety sensors and collision sensors combined with vehicle dynamics processing to control the steering. It requires on-board sensors to measure lane position and lateral deviations and a processor for controlling the vehicle steering.

Since the mapping between objectives and service packages is not always straight-forward and often situation-dependent, these mappings should only be used as a starting point. Users should do their own analysis to identify the best service packages for their region.

The following discusses how the National ITS Architecture provides the transportation service described by this service package. Each numbered item describes the operation of that portion of the service package identified with the corresponding number on the transaction set diagram.

  1. The driver can activate the system and provide steering and other vehicle control inputs to the vehicle (driver inputs).

  2. The vehicle receives basic vehicle measures (speed, surface traction), physical presence of potential obstacles and roadway characteristics input (e.g. lane marker position). If a collision seems possible or if the vehicle seems to be departing from the lane, the vehicle may take evasive action (e.g. adjust steering position, change in throttle position, change in transmission gearing, braking) (vehicle control).

  3. Driver is updated on lateral collision and control conditions (driver updates).
