Radar cruise control, also known as adaptive cruise control, is a type of advanced driver-assistance system for road vehicles that automatically adjusts the vehicle speed to maintain a safe distance from vehicles ahead. The system is based on sensor information from on-board sensors, which may use a radar, laser sensor, or a camera setup. When the system detects that the car is approaching another vehicle ahead, it can automatically brake to maintain a safe distance, and then accelerate when traffic allows it to.
Toyotas Dynamic Radar Cruise Control is an example of this technology, which utilizes a millimeter-wave radar and front sensor to control the distance between the Toyota vehicle and a preceding vehicle. The system will only operate when the cruise control speed is set higher than 28 miles per hour, and it can adjust speeds between 25-110 miles per hour. The driver can choose between long, medium, or short distances to follow the preceding vehicle, and the system will automatically adjust the speed to match the preceding vehicle once it is detected as going slower. The system can be activated by clicking the On-Off button on the end of the right stalk, reaching the desired speed, and then pressing the stalk down. The speed can be increased or decreased by clicking the stalk up or down, respectively, and the DRCC button on the steering wheel can be pressed to adjust follow distances. To cancel DRCC, the driver can pull the stalk toward them or press the brake pedal.
