Forward collision warning systems warn you of an impending collision by detecting stopped or slowly moved vehicles ahead of your vehicle. Forward collision warning use radar, lasers, or cameras to scan the road ahead while you drive. If there is an impending collision, the system will warn you of the danger using lights, beeps, vibrations of your seat, or a combination of these. Some systems may also tighten your seat belt and pre-charge the brakes, making it easier for you to stop as quickly as possible.
SAFE is a revolutionary system that is a pioneer in the automobile safety industry in India. It is a front collision warning system designed to alert the driver in case there is an obstacle in the vehicle’s path. The system is designed specifically for the Indian road conditions and is based on relative velocity, time to collision and distance to the obstacle, which makes it quite accurate with less than 2% false alarms. Specific features of the system are :
The system consists of the following modules :Radar sensor, ECU, Gyroscope, HMI, Speed and power input from vehicle, braking and accelerator module.
SAFE is based on an intelligent algorithm that takes into account the speed of the vehicle, the distance to the object and the relative speed of the obstacle. Alarm 1 in green colour is the initial warning. Alarm 2, in yellow, requires an action from the driver. The final warning, Alarm 3, in red colour comes on when the driver is in the danger zone. It uses a RADAR sensor to detect obstacles in the front of the vehicle. Based on the inputs from the RADAR, it will be sent to the ECU for analysis and the respective output would be given to the HMI, braking, accelerator or data sent to the cloud.
The system can be fitted in any aftermarket 4 plus wheeler vehicle and the installation time takes not more than 2-3 hours. The RADAR sensor is fitted on the front bumper of the vehicle. ECU is inside of the dashboard, gyroscope in the middle of the cabin on the floor with the harness towards the front side of the vehicle, and the HMI on the top of the dashboard visible to the driver.
