Safe speed applications such as ISA are covered in Chapter 9 as they typically rely on cooperative system elements. Platooning the ultimate form of longitudinal sensing and control is addressed in Chapters 9 and 10. For each application area above a general introduction and descriptions of representative systems are provided. A discussion of market aspects is also provided in some cases depending on the degree to which a particular application has entered the market. Evaluation projects and significant R D relating to some of the key application areas are also described. The chapter concludes with an overview of next generation longitudinal sensors and some observations by the author. Rear Sensing for Parking System Description 1 2 Parking consists of short low-speed maneuvers that may be to the front rear or side. In Chapter 6 we saw that steering assist has been employed to assist drivers in the complex maneuvering used for parallel parking. Longitudinally the maneuver is simple and the focus instead is on proximity sensing of nearby objects that are either not directly viewable by the driver or the clearance distance is not apparent. The market pull is strong for such systems as many drivers are at their most uncomfortable when operating their vehicle in a tight parking situation. While the risk to life and limb is almost nil the risk to paint and good relations with the owners of neighboring vehicles is at a critical level Further drivers are aware of the risks and their own limitations in these situations and can easily understand the utility of parking-support sensors. Back-up sensors based on ultrasonic sensing consisting of miniature bumpermounted sensors have been in use for
