Sensor fusion to be standard

by David Zatz on

FCA announced it would expand “sensor fusion” technology — which unrelated to Asian fusion cuisine — to all its US-sale vehicles. This setup, which uses both radar and cameras to increase the accuracy of collision detection-and-avoidance (including automatic braking), is already used on the Durango, Cherokee, Grand Cherokee, 500X, 200, 300, and Charger, and was announced for the 2017 Pacifica.

When a potential impact is sensed, the system pre-fills the brakes and alerts the driver; if there is no response, it taps the brake as another, more tactile alert. If that fails, the car hits the brakes, and can stop the car if it’s going below 25 mph — or reduce the severity of the collision if it’s going faster.

Camera-based and radar-based automatic braking systems were been demonstrated over ten years ago by General Motors, but only recently became generally available, starting in luxury cars and working down; sensor-fusion systems remain unusual.
