LiDAR in Adaptive Cruise Control (ACC)


Blind spots, cruise controls, pedestrian detection and forward collision warning, among others, might be the biggest challenges you may have encountered in your driving experience. Whether you are a car engineer, a tech hobbyist or just an auto enthusiast, one of the things you may want to see improved is the driver safety and assistance. In the last decade, the auto industry has put a lot of efforts on Advanced Driver Assistance System (ADAS) and Adaptive Cruise Control (ACC) through the use of LiDAR technology.

The Radar-based ACC systems have been introduced into the market for nearly 20 years. Nowadays,
ACC technology is getting more mature in terms of both hardware and software, with the development of sensors and algorithms. And implementing LiDAR into the future cars is what most automakers are working on.

LiDAR-implemented systems can enhance various ADAS features, like the automatic emergency brakes, lane centering and ACC. Compared with traditional radar solutions, LiDAR comes with higher resolution and more stable performance and thus guarantees more accurate detection of objects. It also provides precise depth perception and correct distance of up to a few centimeters, making it a better option over cameras. This translates to easy detection and proper vehicle positioning.

Benewake TF03 is a long-range sensor, providing reliable driver safety and assistance solutions with mass-production price. The TF03 is an upgrade of the previous sensors, featuring compact-integration and cost-effectiveness. It solves various challenges that most drivers face, ranging from detecting the distance between the driver and the forward vehicle, especially at dark environment. With the build-in algorithm for raining and fogging weathers, the system offers you a long-range reliable results. 

Features and Benefits   

Up to 180m Detection Range  

TF03 works in the time-of-flight (TOF) principle to generate excellent and consistent performance within the working range.  As an industrial-grade sensor, Benewake TF03 contains an impressive signal processing circuit that provides great detection range of up to 180m. The non-detection-zone of the LiDAR is limited to10cm. It works pretty well in both bright and dark conditions, which makes it a better alternate to cameras.

Compact design with durable construction   

Different from most 360 degree mechanical scanning LiDAR, TF03 is a complete solid-state LiDAR that reached mass production stage. Zero-rotary-component design makes it stable and reliable for assembly lines.

Alongside the solid-state structure, TF03 comes in a compact size. Therefore, the device can be mounted in limited spaces without impacting on the performance. The outer case is made of the aluminum alloy with an infrared band-pass glass. It is resistant to both shock and vibration. The IP67 case provides protection and improves the robustness of the device making it suitable for use in heavy industry and agricultural environments.

Multiple applications   

TF03 is designed in a user-friendly manner. It supports various interfaces like RS232, RS485, UART, CAN-bus and IO-link. It can be used for various applications in smart mobility and intelligent traffic management. Such as:   

Vehicle Collision Avoidance and Adaptive cruise control (ACC)

According to Wikipedia, Adaptive Cruise Control (ACC) is an available cruise control system for road vehicles that automatically adjusts the vehicle speed to maintain a safe distance from vehicles ahead. Control is based on sensor information from on-board sensors. LiDAR based ACC system allows the vehicle to brake when it detects the car is approaching another vehicle ahead, then accelerate when traffic allows it to.

Vehicle Detecting and Counting 

LiDAR with higher refresh rates than other sensing solutions, has excellent performance on detecting fast-moving targets, such as vehicles on the highway. The accuracy of vehicle detecting and counting  is around 98-99% in Benewake’s previous statistics*.

* The results could be affected by the environment, the weather conditions, the vehicle speed and other factors.

Vehicle Type Recognition  

Benewake TF03 is an intelligent LiDAR that can distinguish the type of vehicles for traffic management organizations or fleet management companies. With Benewake’s build-in algorithm of vehicle type recognition, TF03 is a cost-effective solution for traffic management in smart cities.

Vehicle Type Recognition


LiDAR technology is setting off waves in the auto industry. With the ability to provide better driving assistance and safety solutions, LiDAR has solved various problems that most drivers have experienced. We all agree that multi-sensor solution is the trend of the future. LiDAR can be coupled with camera AI system, radar system and other short-range sensors to assist your daily driving.
