Everything you should know about Car Safety and Security Functions
This is how active safety systems work and how they may save you from a car accident. The amount of driver help safety and security functions available to car buyers has grown fast in the previous several years, so it’s straightforward to be unclear about which technologies do what. Focusing on how these functions operate and how they can help you avoid an accident is an answer to selecting if option offers that include them are well worth the extra coin.
If you buy a car with some or all of these features, it is important to understand how they work and why they often don’t and what to do if one needs to alert you to an impending incident. To help, we have collected all of the present driver help functions here to explain each process.
Adaptable Cruise Control
Adaptable cruise control is a comfort and ease that functions the car’s radar and camera segments to change the set cruising speed if it locates a slower car ahead. When adaptable cruise control is operating, the car will hold a certain distance from the car in the front; many cars feature three set choices for the following space. Several advanced versions of the feature will also bring the car to a complete stop if the car ahead stops and will then begin to back up when traffic begins to go. This feature is quite useful and minimizes driver exhaustion by using cruise control in heavy traffic driving circumstances.
Active Park Help
Using radar and sonar, cars built with active park help will look for and determine empty parking places. After that, they actively steer the car into all of them as the driver operates the brake and accelerator. A few producers offer both perpendicular and parallel parking capability. However, many limit the car to one or the other. In our experience, these types of systems usually are not the best and are very easily triggered up by curbs, near parked cars, or other environmental factors.

Automatic Emergency Braking
Using forward dealing with radar and cameras, cars with automatic emergency braking will alert the driver of an impending forward collision with another car, pedestrian or thing, then brake the car by the driver if she or he requires no action. A few cars are available with an identical automatic emergency braking system that performs when the car is reversing. We examined automatic emergency braking on many cars. We identified that even though they are doing work as planned, they do not usually brake tough enough or early on to stop the collision. Therefore drivers shouldn’t depend upon these types of functions. Several systems work only at low speeds, though more innovative systems work even at highway speeds. Automatic emergency braking will be phased into all new cars as a standard function by 2022.
Automatic High Beams
Head-lamp systems that automatically switch to high beams can seem like a new feature. However, they have been around since the 1950s, when they first showed on General Motors’ Cadillac, Buick, and Oldsmobile cars. In contrast to the earlier systems that depended on light-sensitive sensors that proved to be somewhat unreliable, the present automatic high beams are controlled by high technology camera segments that may more easily discover between an oncoming car’s head-lamps and the reflection from road signals.
Blind Spot Monitor
Utilizing sonar sensors in the backside bumpers or usually cameras in the exterior mirrors, blind-spot monitoring systems check out surrounding roads and can warn the driver of other cars that could be in the driver’s blind spot or covered by the car’s roof pillars. Most cars with this feature have warning lights in the external mirrors that light up or display when a car is found nearby and one lane over; a few cars also beep if the turn signal is turned on while a car is in the adjacent lane. We find blind-spot monitors generally function quite nicely and can help keep you from cutting off another driver.
Driver Attention Monitor
This kind of system watches the driver help avoid accidents due to exhausted and unfocused driving. Many systems use devices to observe the car’s actions and volume of steering modifications to determine if the driver is carefully driving or is tired or messaging. These systems give a visual or audible awareness of inspiration, having a break from driving to improve. More modern designs, such as the one used in Cadillac’s Super Cruise, use driver-facing cameras that watch out for signals of sleepiness.
Forward Collision Alert
Like adaptable cruise control, forward collision warning systems use radar, cameras, or both to see the road forward for slow or stopped traffic. Forward collision caution is a more straightforward form of collision mitigation. It will inform the driver, usually with both a visual and an audible warning, that a collision is imminent, hoping that the driver will hit the brakes. These systems are often associated with automated emergency braking that will brake for the driver if absolutely no action is taken. Still, drivers should know that not all cars combine both functions.
Lane Departure Caution
Lane departure alert is generally a camera-based driver help function that looks for lane markings and warns the driver if the car is in danger of walking around out of its lane or has begun to exit the lane with no turn signal being turned on.

Lane Keeping Help:In contrast to lane departure warning, a lane keeping help function can help prevent lane departure by making small improvements to the steering to maintain the car in the intended lane. Although some systems still provide a piece of audible or visual information to match the lane departure, some cars with lane keeping help will just silently recenter the car in the lane. It usually is effortless to feel from behind the wheel because the car shifts direction and the steering wheel moves without any steering adjustment by the driver.
Night-vision functions are not yet a standard driver help feature. Currently, night-vision systems are available on luxury cars from brands like BMW, Audi, Cadillac, and Mercedes-Benz and use forward-facing thermographic cameras to watch for pedestrians and animals and cars not easily seen in the dark by the naked eye. Generally, on the car’s infotainment screen, a small display shows an image of what is ahead, with potential difficulties outlined in a heat signature. Depending on the system, the driver can get a separate audible or visual alert to recognize a challenge. We have discovered these kinds of systems challenging to drive by.
Parking sensors, also called proximity sensors, help the driver in parking maneuvers by using ultrasonic transducers to find challenges such as parked cars, high curbs, or bollards and alert the driver with a series of beeps that increase in tempo as the car nears the object. Sensors are usually located on the front side and backside bumpers.
In an attempt to keep those outside the car, many innovative cars include a pedestrian detection system that uses cameras to watch for people crossing the street or riding their bicycle in a shared lane. A few cars with this function may also automatically brake if the system senses a pedestrian’s collision is imminent.

Backside Cross-Traffic Alert:Using similar ultrasonic transducers as the cars parking detector system or the sonars for blind-spot monitoring, backside cross-traffic alert may alert the driver of cars or pedestrians coming to the backside of the car from the side. The function is beneficial when backing out of parking spots in jam-packed lots. A few cars will also apply the brakes automatically to stop the car when it detects a collision is possible.
Partially Autonomous Driving Mode
Like Tesla’s Auto-pilot system, Nissan’s ProPilot Help, and Cadillac’s Super Cruise, partially autonomous driving modes are easy features designed to reduce driver fatigue. Though these functions don’t flip your car into a fully independent car , they do more of the driving than simple, adaptable cruise control. For instance, both Tesla’s and Cadillac’s systems allow the car to steer itself on the highway and center by itself in the planned lane while keeping a set speed. Several methods will change lanes if required, either automatically or if the driver activates the turn signal.
Traffic Signal Identification
One more camera based system, traffic signal identification, looks for road signals, for example, a posted speed limit, and presents the information to the driver once again. A few systems can also identify signals which indicate restrictions on moving and other road warnings. The traffic signal is often projected on the car’s head-up display, gauge display, or infotainment screen to remind the driver. A few cars will show the speed limit with a red line on the speedometer.
