Customer Stories. Many automotive manufacturers equip their development cars with numerous additional hardware sensors to gather data for diagnosing issues and refining the design. Once the car transitions to production, many of these sensors are removed to reduce costs. In some cases, however, the hardware sensors can be replaced with virtual sensors, which are cheaper software alternatives that can further improve safety, efficiency, and driver comfort. These sensors are based on deep learning networks designed to run on resource-limited ECU microcontrollers. This automated workflow replaced a manual workflow that was both slower and relied on a trial-and-error approach. Most deep neural networks are designed to run on computers with significantly more processing power and memory capacity than an automotive ECU.

I asked another MB owner at work about it and she said to not worry, it's probably just an 02 sensor issue due to the weather change. Today on my lunch break the car did a strange shift when I pulled out into traffic. When I got off work a few hours later, the car wouldn't shift out of low gear.

Throughout the last twenty years, Mercedes-Benz equipped numerous vehicles in their lineup with air-ride from the factory. This system, although complex, shouldn't be feared; it's broken up into relatively easy-to-service components. Introduced on the W S-Class for the model year, Mercedes-Benz began equipping various models throughout their lineup with an air-suspension system dubbed "Mercedes-Benz Airmatic". This system replaced the traditional coil-springs found on cars leading up to this time with air-springs with electronic level control and adaptive damping at all four corners. The combination of adaptive damping that adjusts based on road quality and driving style in concert with air springs makes for an extremely comfortable ride. You might be asking why you would want such a complex system in place of the much simpler coil-spring setup. There are a number of reasons, some of which make it well worth it over the traditional coil-spring suspension. This is the brain of the system.

Again, a symptom of this fault can be your engine warning light suddenly coming on. Unfortunately, over time, NOx sensors can malfunction, leading to a range of problems in your vehicle, including reduced power, acceleration and performance. Learn more about Mercedes-Benz. This automated workflow replaced a manual workflow that was both slower and relied on a trial-and-error approach. Having successfully implemented its first use case—a virtual sensor for piston pressure—with this workflow, the Mercedes-Benz team is now applying the same process to additional sensors and other deep learning applications for ECU targets. Once the car transitions to production, many of these sensors are removed to reduce costs. Get a free trial. CPU, memory, and performance requirements met.

This process took Mercedes-Benz weeks to complete, produced unreliable results, and was difficult to teach to new team members. It uses a lambda probe in the exhaust to measure how much oxygen is present, feeding this information back to the engine management system.

In some cases, however, the hardware sensors can be replaced with virtual sensors, which are cheaper software alternatives that can further improve safety, efficiency, and driver comfort. Get a free trial. The Mercedes-Benz team worked with MathWorks engineers to implement an optimized workflow to convert Python deep learning models into code and parameters that can be transferred to their ECU integration pipeline. Recent Posts. Most deep neural networks are designed to run on computers with significantly more processing power and memory capacity than an automotive ECU. After verifying the fixed-point model via simulation in Simulink, the team hands the model off to a third-party software integrator, who implements it on the ECU with other software components.
