Copyright Goodheart-Willcox Co., Inc. 514 Section 5 Electrical and Electronic Systems Technology • A rear cross traffic alert (RCTA) uses sensors in the corners of the rear bumper to detect vehicles approaching from the side and rear of the vehicle while it is traveling in reverse. • A pedestrian detection system (PDS) will alert the driver and/or automatically brake if there is a pedestrian in the vehicle’s path. • A road sign recognition (RSR) system uses forward- facing cameras to detect road signs. • A lane-keeping assistance system controls steering to keep the vehicle within the driving lane. • A road-departure assist system cuts back the throttle and applies the brakes if it detects that a vehicle has left the road. • A driver monitoring system (DMS) uses a camera in the dash to monitor the driver’s alertness. • A night vision system uses an infrared camera and monitor system to help the driver view through vision-impairing atmospheric conditions. • Active parking assistance systems use computer control to back up, steer, and brake a car into a parking space. • A trailer assist system helps the driver during backup maneuvers when a trailer is attached • Servicing vehicle security, navigation, and driver assist systems usually involves part replacement. Activities 1. Write a definition for each of the Technical Terms listed at the beginning of this chapter. If you cannot define one or more of the terms, review the corresponding chapter content or refer to the Glossary for more information. 2. Pick any make and model car with a navigation system. Determine how to troubleshoot the vehicle’s navigation system with factory service information. Write a short report of anything you learned about testing and repairing or replacing the vehicle's navigation system. 3. Write a report on the operation of one of the advanced driver assistance systems described in this chapter on a vehicle make and model of your choice.
