The Future of Cruise Control

Don’t you hate when you’ve just set your cruise control on the highway, and then someone pulls in front of you, forcing you to adjust your speed? While cruise control helps give your foot a break, it doesn’t account for the ebb and flow of normal traffic. Seldom is there a road where you can let your cruise control take over for miles and miles on end.

This is the type of situation when Toyota’s available Dynamic Radar Cruise Control (DRCC) [1] -- can give you a little less to do and a lot less to worry about.

How The Technology Works


DRCC automatically adjusts your Toyota’s speed in order to help maintain a safe following distance. It’s not magic. It works by using forward-sensing radar technology installed behind the grille of your Toyota. The radar detects the speed and distance of the vehicle ahead of you and adjusts speed accordingly.

DRCC is similar to conventional cruise control, keeping your car at a preset speed. But DRCC can do more. It automatically adjusts speed to keep a safe distance between vehicles in the same lane.

If the lead vehicle slows down, the system can slow your vehicle to help maintain a preset following distance. Then, when the road is clear, the system will accelerate your vehicle back to the original cruising speed.

The Future, Today

DRCC can be used with Toyota’s Pre-Collision System [2] (PCS, available in select Toyota vehicles) to help reduce the severity of a front-end collision. Based on the vehicle’s closing speed to a potential impact, a warning light, a warning display and a buzzer will automatically alert the driver that evasive action or braking is needed.

If a front-end collision is unavoidable, PCS automatically retracts the driver and front passenger-side seatbelts and preps Brake Assist (BA) [3] for increased braking power the moment you step on the brake pedal.

If you don’t apply the brakes, the system automatically applies maximum braking power for you prior to impact.

If no impact occurs, both seatbelts and BA return to their normal pre-collision state after you stop your vehicle and put it in Park.

Toyota is working to help enhance road trip safety. Look for Dynamic Radar Cruise Control and the Pre-Collision System on select Toyota vehicles.
