Millimeter wave (mmWave) is a special class of radar technology that uses short wavelength electromagnetic waves. Radar systems transmit electromagnetic wave signals that objects in their path then reflect. By capturing the reflected signal, a radar system can determine the range, velocity and angle of the objects.
The millimetre wave radar is often located just beneath or below the front Honda logo. It is located in the lower centre region of the front bumper lower grille or to the side, below the front bumper side trim, on some models.
Need for IDAS (Integrated Driver Assistance System)
According to estimates, each year, 1.35 million people die and 50 million people are injured as a result of traffic accidents throughout the world. However, due to difficulties such as traffic congestion and aggressive driving, lane changeover, these cars are prone to accidents. The context aware driver assistance system I-DAS is designed to help drivers in responding to changes in the environment. Road situation analysis for driver assistance and safety warning is an interdisciplinary endeavour involving many research fields.

Honda P2583-97 Dust or Dirt On The Millimeter Wave Radar
The Front Distance Range Sensor detects light reflected from a vehicle ahead by irradiating laser forward and calculates a distance from the vehicle ahead as well as a relative speed. The Front Distance Range Sensor transmits the presence/absence of the vehicle ahead as well as the distance from the vehicle to the vehicle Cruise Control Unit based on the detected signal. The Cruise Control Unit requests the Engine Control Module (ECM) to set the OBDII code P2583-97 when the vehicle’s Cruise Control Unit loses connection with the Front Distance Range Sensor.

Since 1986, when the Prometheus (Programme for European Transport with Highest Efficiency and Unprecedented Safety) initiative began, Adaptive Cruise Control has been in the works. To follow a car ahead and maintain a safe distance, today’s Adaptive Cruise Control uses radar or laser technology. It allows the vehicle to maintain a constant speed while automatically stopping and accelerating in response to changing traffic circumstances.
Lane Departure Warning
When the automobile begins to leave its lane without evident input from the driver, lane departure warning warns the driver. The electronics can follow the lane lines on the road ahead thanks to a video camera in the rearview mirror. The programme calculates the car’s location in the lane using this video picture, then compares it to other inputs from the steering angle, brake, and accelerator position sensors. An auditory or haptic warning, such as vibrating steering, alerts the driver if the automobile begins to wander off track for no apparent reason.
Collision Avoidance System
Collision warning/avoidance systems enable the driver to take necessary corrective measures in order to reduce or totally prevent a collision. The proximity of the car to other vehicles around it, the amount of speed reduction required while travelling around a curve, and how near the vehicle is to running off the road are all risks that sensors can detect. Sensors in the system send and receive signals from other cars and road obstructions. When a motorist is going to change lanes and the car is in the blind spot. This is an excellent example of how the system works. The sensors will identify that car and alert the driver, perhaps saving him from a severe collision.
