Autonomous Cars Unveiled: A Deep Dive Into Sensor Technology Advancements


The automotive industry is among the most crucial ones for the future of our civilization. There are countless reasons for this being the case. Transportation is necessary for growth and crucial for fields such as logistics. You will see that any organization, even the government, cannot do without this. Thankfully, modern technologies have now enabled the industry to reach new heights. We can expect that to happen shortly.

The foundations have already been set; we need to wait it out. However, modern technologies are not always clear to people who lack experience in a particular field. In fact, you will see that most people don’t have the right idea on certain aspects. Investigating all these particularities is necessary to comprehend their importance. So, you should read, which you should do if you want to learn more about lidar technology.

Technological revolutions occur once in a century, and we believe our generation is right in the middle of one. The progress the next one will make is something our civilization has not seen before, especially in the automotive industry. Today, we want to touch upon the concept of autonomous cars, focusing on sensor technology that makes this possible.


The Concept of Autonomous Vehicles

The concept of autonomous cars has risen in the last couple of years. The whole point is for them to act independently from human intervention in various fields. A good example is humans not interfering in different fields, such as tire pressure or fuel efficiency. While this does not mean humans will have no hand in it, human participation is crucial. However, humans will have no hand in discovering potential issues.

Autonomous vehicles rely on a completely different set of requirements. For instance, they rely on actuators, sensors, and highly complex algorithms. Today, software development is a vital part of the automotive industry. In the future, this branch of the industry is going to boom. What we see now is just the foundation for what is to come in the next decades.

A good example of an autonomous vehicle is that they can learn and maintain a map of their surroundings. By saying that, we don’t mean the navigation only. Instead, the vehicles will understand the requirements to cross a certain terrain without any consequences. Of course, the final decision is upon a human. The vehicles are just going to indicate whether there is a problem on the road or not.

As you can presume, these in-built software are highly complex. Today, you can find them only in the newest generation of vehicles. You can find them in some older ones, but sensors don’t fulfill their full capacity in those models. Sensors are a key ingredient, which we will discuss in depth later in the article.


The Commonest Types of Sensors

Now, we want to discuss the most common type of sensors we can see in the automotive industry.

Vehicle Speed Sensor

Vehicle speed sensor is a device that constantly monitors the rotational speed of wheels. Of course, some models have a sensor for each wheel, but today, having one is prevalent. Monitoring the rotational speed ensures that the driver completely controls the vehicle. Think about it: This is the safest way to prevent unpleasant situations. We all know they are quite common, and preventing them is crucial.

When it comes to the data it encompasses, it is much more than it meets the eye. For instance, you will see that it monitors traction control, anti-lock braking, and, of course, electronic stability control. By having control over all these elements, the driver will have a great driving experience while driving on terrains that might spark some problems down the road. Safety comes first, and this sensor provides exactly that.


Pressure Sensor

Pressure sensors play a vital role in modern vehicle systems. They are located in practically all the vehicle parts to monitor the pressure applied to them. So, you can see this one differs from a vast majority of other types since there is more than just one. A particularly important one is known as fluid pressure. The technologies needed for this sort of monitoring are capacitive and piezoresistive.

They help by interpreting the signals sent by different vehicle parts and translating them into what you can read without problems. Pressure sensors are crucial for your car’s overall well-being. But they also apply to the fuel efficiency, which is crucial today. Also, placing them in your tires can help ensure tire safety. As you can see, their role is quite wide, and nowadays, our cars cannot do without them.

Engine Speed Sensor

The next one is important on a variety of levels. You will see people addressing it as a crankshaft position sensor. However, the most prevalent name for this one is engine speed sensor. The engine is something our cars cannot do without. With that in mind, manufacturing companies must ensure the sustainability of this part and provide the best possible protection from whatever problems might occur.

We get the data from our engine by utilizing magneto-resistive technology. How does this one work? The best way to describe it is a conversion of mechanical motions into electricity. That electricity is later transformed into signals, later translated to display where we can see them. As you can presume, having this sensor in your car is crucial for planning careful engine management. Otherwise, you cannot keep them in proper condition.

For those who don’t know what engine management is, we are talking about controlling the fuel injection timing and ignition timing. The whole point is to synchronize both elements and turn them to the vehicle’s benefit. Naturally, it also monitors fuel consumption, which is exceptionally important. You wouldn’t like to be left without fuel while in the middle of nowhere, right?


The Bottom Line

Sensors are here to say, and there is no sign of them stopping soon. Here, you can see why they are so relevant to the concept of autonomous cars. Also, we discussed different sorts of sensors in depth. We are certain you will find this insight to be of great help.
