Radar Sensors in ADAS

Image
Radar sensors are used in ADAS to detect the distance and speed of other vehicles, as well as the shape and size of objects in the road. This information is used by the ADAS system to perform a variety of tasks, such as: Adaptive cruise control:   Radar sensors are used to detect the distance and speed of the vehicle in front of the ADAS-equipped vehicle. This information is used by the ADAS system to adjust the speed of the ADAS-equipped vehicle to maintain a safe distance from the vehicle in front. Lane departure warning:  Radar sensors can be used to detect if the ADAS-equipped vehicle is drifting out of its lane. If the ADAS system detects that the vehicle is drifting out of its lane, it will warn the driver. Blind spot monitoring:   Radar sensors can be used to detect if there are vehicles in the blind spots of the ADAS-equipped vehicle. If the ADAS system detects that there are vehicles in the blind spots, it will warn the driver. Forward collision warning:  Ra...

Adaptive Cruise Control (ACC) - How it works

Image
The internal blocks related to adaptive cruise control (ACC) system and their functionality are as follows: Radar sensor: The radar sensor is used to detect the distance and speed of other vehicles. It is typically mounted in the front of the vehicle, and it uses radio waves to scan the road ahead. The radar sensor sends out a signal, and when it bounces back from an object, the sensor can determine the distance and speed of the object. Control unit: The control unit is the brains of the ACC system. It receives data from the radar sensor and uses this data to determine the speed of the vehicle. The control unit then sends a signal to the actuator, which controls the brakes or accelerator. Actuator: The actuator is responsible for applying the brakes or accelerating the vehicle. It receives a signal from the control unit, and it then applies the brakes or accelerates the vehicle as necessary. Front camera: The front camera is used to detect lane markings and the prese...

Adaptive Cruise Control (ACC)

Image
Adaptive cruise control (ACC) is a type of Advanced Driver Assistance System (ADAS) that automatically adjusts the speed of a vehicle to maintain a safe distance from the vehicle in front of it. ACC systems use radar or lidar sensors to detect the speed and distance of other vehicles, and they use this information to adjust the speed of the vehicle accordingly. ACC systems use a variety of sensors to monitor the road and surrounding environment, including: Radar : Radar sensors are used to detect the distance and speed of other vehicles. Laser : Laser sensors are used to detect the distance and speed of other vehicles, as well as the shape and size of objects in the road. Camera : Cameras are used to detect the lane markings and the presence of other vehicles. ACC systems can be classified into two main types: Full-speed range :  Full-speed range ACC systems can operate at all speeds, from a standstill to the maximum speed of the vehicle. Partial-speed range:   ...
