Intended for highways and similar to “constant speed” cruise control, Dynamic Radar Cruise Control (DRCC)
lets you drive at a preset speed. DRCC uses vehicle-to-vehicle distance control, which is designed to adjust your speed, to help you maintain a preset distance from vehicles ahead of you that are driving at a slower speed. DRCC uses a front-grille-mounted radar and an in-vehicle camera to detect vehicles and their distance. If a driver is traveling slower than you, or within your preset range, DRCC will automatically slow your vehicle down without deactivating cruise control. If DRCC determines you need to slow down more, an audio and visual alert notifies you and brakes are applied. When there’s no longer a vehicle driving slower than your set speed in front of you, DRCC will then accelerate and regular cruise control will resume. Prius features Full-Speed Range DRCC,
which is designed to operate between 0-110 mph. This enables low-speed following, matching speed and, under certain circumstances, stopping before colliding with preceding vehicles on highways.
