Reasons to Opt for Automotive Testing Services

Software testing in the automobile field ensures that integrated embedded systems work in alignment with the AUTOSAR (Automotive Open System Architecture) standard and stringent safety regulations. It checks the adaptability of in-built features, such as cruise control and tyre-pressure monitoring system to the condition of the road and the comfort of the driver. Let’s see how it improves other requirements, like:

#1 Best Functionality

Functionality is a significant part of software integration testing when it comes to the automotive industry. It is performed thoroughly to make sure that software fulfills low-level and high-level requirements for running manually or autonomously. They act as safety checks that need to cross the benchmark in order to give safety certification.

#2 Reliability

Generally, the capability of a vehicle reduces to a great extent over some time. But this process will slow down if you get automotive testing done at least once in a while. And the most important part? If you opt for automotive software testing services, it will check the entire functionality and enhance the quality of your product by modifying essential features.

#3 Auto-navigation

When it comes to smart cars, autonomous driving & auto navigation play an imperative role in terms of safety. In fact, they enhanced the signaling system of integrated GPS to work without internet connectivity but still offered live assistance for drivers big time. Another advantage, according to an accomplished automotive tester is that updated navigation software can provide clear traffic and weather updates to pay attention to.

#4 Increased Alert System

Here, a seasoned automotive tester performs a worst-case execution time analysis to validate time-sensitive sections of code. For instance, they test the airbag deployment software with several degrees of force to enhance its execution speed and correct scope for performance. In a similar manner, it tests the other important functionalities that should be executed quickly.

#5 Fully-functional ECU

ECU stands for Electronic Control Unit, which is a small device that has firm hand over interoperations, such as:

Automatic headlights
Driver seat control
Keyless start

So, testing these features twice yearly is extremely necessary, especially for cars post five years of purchase because they improve their quality of work for long-lasting.

As per a leading automotive testing company, AUTOSAR is a high standard of quality, which offers a set of guidelines for embedded systems in the automobile industry.

Types of Tests Performed in Automotive Testing

Just so you know, automotive testing services are way more expensive, time-consuming, and consume a lot of repetitive labor work. Fortunately, we have technology that deals with such issues. Take a look at the pointers listed below to perceive multiple ways of autonomous testing:

1. Software-in-the-loop testing

Software-in-the-loop testing inspects the code with a simulation to fix bugs. Doing this decreases the build time to a large extent while enhancing the quality of software as well. It is the main reason many car brands examine their safety and navigation systems deeply using this method before developing the final build of the application.

Some of the benefits of SIL according to an automotive testing firm are:

Monitoring and reporting of test results is a breeze.
SIL testing is fast and scalable.
Enables software to incorporate new functions into current hardware components.
Most automotive software testing techniques are automated.
Allows to test every ECU’s code individually and easily.

2. Hardware-in-the-loop testing

Hardware-in-the-loop testing is a bit different from the SIL method for a specific reason. Here, simulators are extensively tested with an ideal output range prior to connecting with the Electronic Control Unit. Doing this mitigates the chance of system failure post installation. Additionally, HIL emulates the cameras and radars with real-time data input, which is why it is very time-consuming and pricey for automotive testing.

Some of the benefits of HIL testing are:

High safety and reliability
Fewer chances of system malfunction
Simulates the whole vehicle function
Minimizes the need for rigorous testing down the line
Accommodates several tests simultaneously

Both automotive testing services have a unique set of advantages to enhance quality and brand reputation. It depends on what qualities you want to include in your application.

Tools and Technologies Used For Automotive Testing

Software testing in the automobile industry requires the utilization of multiple tools and technologies to support and automate the process.
