Delphi ESR with Firmware Version: 9.21.21

Delphi’s multimode ESR combines a wide field of view at midrange with long-range coverage to provide two measurement modes simultaneously. While earlier forward-looking radar systems used multiple beam radars with mechanical scanning or several fixed, overlapping beams to attain the view required for systems like adaptive cruise control, Delphi’s multimode ESR provides wide coverage at mid-range and high-resolution long-range coverage using a single radar. Wide, mid-range coverage not only allows vehicles cutting in from adjacent lanes to be detected but also identifies vehicles and pedestrians across the width of the equipped vehicle. Long-range coverage provides accurate range and speed data with powerful object discrimination that can identify up to 64 targets in the vehicle’s path.

Delphi’s technologically advanced ESR uses proven solid-state technology plus class-leading performance, packaging and durability to offer customers game-changing forward radar detection. The quality of data provided by Delphi’s system enables powerful functionality including adaptive cruise control, forward collision warning, brake support and headway alert.
