The Difference Between Driver Assist and Autonomous Semi-Trucks: Explained

As technology advances, so does the transportation industry. Today, there are more advanced features in semi-trucks than ever before. Driver assist systems and autonomous semi-trucks are two such features that have been gaining popularity in recent years. However, many people are confused about the differences between the two. In this article, we will explore what driver assist and autonomous semi-trucks are, how they differ, and what they mean for the future of trucking.




What are Driver Assist Semi-Trucks?

Driver assist systems for semi-trucks are becoming increasingly common. These systems are designed to support the professional driver by automating specific tasks. These tasks include maintaining a safe distance from other vehicles on the road, staying within a lane, and even parking the vehicle. The driver remains responsible for the vehicle, and the system is meant to assist the driver and make driving safer and more comfortable.


Driver assist systems use a combination of sensors, cameras, and algorithms to monitor the vehicle's surroundings and assist the driver. These systems are not meant to replace the driver but rather to enhance their driving experience. The driver is still responsible for controlling the vehicle, and the system is only meant to provide additional support.


Common Examples of Driver Assist Semi-Trucks

There are several types of driver assist systems for semi-trucks, and they can vary depending on the manufacturer and the model of the vehicle. Here are some common examples of driver assist systems for semi-trucks:


Adaptive Cruise Control (ACC): ACC is an advanced cruise control system that uses radar or sensors to monitor the distance between the semi-truck and the vehicle in front. ACC will adjust the semi-truck's speed to maintain a safe distance from the vehicle ahead.


Lane Departure Warning (LDW): LDW uses cameras or sensors to monitor the semi-truck's position within the lane. If the semi-truck begins to drift out of its lane, the system will alert the driver to bring the semi-truck back to its lane.


Blind Spot Monitoring (BSM): BSM uses sensors to monitor the semi-truck's blind spots. If another vehicle is detected in the blind spot, the system will alert the driver to prevent a collision.


Rearview Camera: A rearview camera is a backup camera that displays the area behind the semi-truck to help the driver with parking and reversing.


Automatic Emergency Braking (AEB): AEB uses sensors to detect potential collisions and applies the brakes if the driver does not react in time.


Parking Assist: Parking assist uses sensors and cameras to help the driver park the semi-truck. The system will guide the driver into a parking space by controlling the steering, and the driver is responsible for controlling the throttle and the brakes.


What are Autonomous Semi-Trucks?

Autonomous semi-trucks, also known as self-driving semi-trucks, are capable of driving themselves without intervention from the driver. These vehicles use sensors, algorithms, and machine learning to perceive and interpret their environment, make decisions, and control the semi-truck's movements. In other words, autonomous semi-trucks do not require a driver to operate.


Autonomous semi-trucks are classified into different levels based on their degree of automation. The levels range from 0 to 5, with 0 being no automation and 5 being full automation. Level 1 and 2 vehicles are considered driver assist systems, while level 3 and above are classified as autonomous vehicles.


Levels of Autonomous Semi-Trucks

Level 0: No Automation The driver is responsible for controlling the semi-truck at all times.


Level 1: Driver Assistance The semi-truck can assist the driver with steering or braking, but the driver is still responsible for controlling the semi-truck.


Level 2: Partial Automation The semi-truck can assist the driver with steering and braking, but the driver is still responsible for controlling the semi-truck.


Level 3: Conditional Automation The semi-truck can drive itself under certain conditions, but the driver must still be ready to take control at any moment. The semi-truck can handle most driving situations, but it may require the driver to intervene in some cases.


Level 4: High Automation The semi-truck can drive itself in most situations without requiring any input from the driver. However, the driver may need to take control in rare situations.


Level 5: Full Automation The semi-truck can drive itself in all situations without any input from the driver. The driver is not required to be present in the semi-truck.


Common Examples of Autonomous Semi-Trucks

While fully autonomous semi-trucks are not yet widely available, there are several examples of autonomous semi-trucks currently being tested or in development:


Tesla Semi: The Tesla Semi is an electric semi-truck that features autonomous driving capabilities, including automatic emergency braking, lane departure warning, and collision avoidance. Tesla is also developing a more advanced autonomous system called Full Self-Driving (FSD), which is currently being tested.


TuSimple Autonomous Trucks: TuSimple is a company that is developing self-driving semi-trucks for long-haul deliveries. Their trucks use cameras, radar, and Lidar to navigate highways and complete deliveries.


Embark Autonomous Trucks: Embark is another company that is developing self-driving semi-trucks for long-haul deliveries. Their trucks use sensors and artificial intelligence to operate on highways and optimize logistics operations.


Plus Automated Trucks: Plus is a company that is developing semi-autonomous trucks that use advanced driver assistance systems to assist drivers. Their system includes features such as adaptive cruise control and collision mitigation.



How Driver Assist Systems and Autonomous Semi-Trucks Differ

While both driver assist systems and autonomous semi-trucks use technology to assist or replace the driver, there are some key differences between the two.


Driver assist systems are designed to support the driver by automating specific tasks such as maintaining a safe distance from other vehicles or staying within a lane. The driver is still responsible for controlling the semi-truck, and the system is only meant to assist the driver. The driver is required to remain alert and ready to take control at any moment.


Autonomous semi-trucks, on the other hand, are capable of driving themselves without intervention from the driver. They use sensors, algorithms, and machine learning to perceive and interpret their environment, make decisions, and control the semi-truck's movements. In other words, autonomous semi-trucks do not require a driver to operate. However, the driver may still be required to take control in certain situations, depending on the level of automation of the semi-truck.


The Future of Driver Assist and Autonomous Semi-Trucks

Driver assist systems and autonomous semi-trucks are becoming more common in today's vehicles, and they are likely to play a significant role in the future of trucking.
