Advanced Driver Assist Systems (ADAS) are comprised of numerous advanced technologies that assist the driver in a variety of ways. Whether it’s helping to keep the car stable while you’re driving on an icy road or monitoring your blind spots when changing lanes on the highway, these systems aid in keeping you safe on the road.
Today, there are various components that make up ADAS including electronic stability control (ESC), adaptive cruise control (ACC), lane departure warning and lane assist, blind spot monitor (BSM), rear camera, night vision, and 360 surround view.
Do you know what each of these components does?
Beck’s Auto Center, your local auto repair shop in Lafayette, Indiana, is here to walk you through 4 ADAS features every shop should be well versed in:
- Electronic Stability Control
- Adaptive Cruise Control
- Lane Departure Warning and Lane Assist
- Blind Spot Monitor
What is Electronic Stability Control?
Electronic Stability Control (ESC) is a vehicle safety system that uses sensors to identify when a vehicle is entering a situation where the vehicle may lose control. ESC automatically applies braking and/or reduces engine power. This technology helps vehicles maintain control in extreme driving situations like:
- Rapid acceleration
- Sudden braking
- Hard impacts
How does Electronic Stability Control Work?
ESC, or Electronic Stability Control, is an automotive safety feature that combines the following systems:
- Anti-lock brakes (ABS)
- Anti-slip regulation (ASR)
- Electronic brakeforce distribution (EBD)
- Traction control
It uses sensors to monitor inputs from multiple channels, including steering angle, lateral acceleration, tire slip, accelerator pedal application (pressure) and vehicle speed. When it determines a vehicle is starting to lose traction, then brakes are applied as needed in order to keep the car from spinning out of control.
What is Adaptive Cruise Control (ACC)?
Adaptive cruise control (ACC) is a subset of your typical cruise control system that allows vehicles to automatically maintain a safe distance between themselves and other vehicles on highways. To detect vehicles in front of or behind them, the system uses:
- video cameras
- infrared sensors or lasers
Engine speed is adjusted accordingly to enable drivers to set their desired speed. This eliminates the need to constantly adjust your speed while traveling on major roads. ACC makes highway driving easier and safer by controlling your vehicle’s acceleration and deceleration based on real-time traffic conditions.
How Does ACC Work?
The adaptive cruise control system monitors traffic conditions ahead of your vehicle. Your speed is automatically adjusted to keep a safe distance from other vehicles. In most cars with ACC, you can control how closely it tracks another vehicle with a steering wheel-mounted switch. If your vehicle is equipped with Lane Departure Warning (LDW), it will gently apply pressure to make sure you stay in your lane as well.
Types of Lane Departure Warning & Assistance (LDW/LA)
There are two main types of this technology on the market. Lane Departure Warning (LDW) systems and Lane Keep Assist (LKA) systems aim to help prevent accidents by alerting a driver when their vehicle begins to stray from its lane.
In some vehicles, these systems also may be able to take corrective action for drivers. This system uses sensors along with lane markings and other cars on the road to measure how fast another car is approaching—and alerts you if it’s coming up too quickly so that you can slow down or speed up as needed.
What Is the Lane Departure Warning/Lane Assist System Used For?
This advanced driver assist system uses cameras to detect objects near your vehicle. Once it senses that you’re drifting out of your lane, it alerts you with a series of visual and audible warnings. If you don’t steer back into your lane within a few seconds, Lane Departure System applies corrective steering to help guide your vehicle back into its proper position.
What is the difference between Lane Departure Warning and Blind Spot Monitor?
Both do work in similar ways. Lane departure warnings use cameras or sensors to detect when you get too close to the edge of your lane, while a blind spot monitor will alert drivers if there is another vehicle or other objects in an area that is obscured by your mirrors or outside your direct line of sight.
This system uses radar sensors to locate vehicles next to your car. An audible warning system alerts you that there is something near your side mirror and on many models, a small red light will flash on your rear view mirror to grab your attention.
