Increasing Efficiency in Hybrid Electric Vehicles by Reducing Switching Losses in Inverters
Increasing Efficiency in Hybrid Electric Vehicles by Reducing Switching Losses in Inverters In the ongoing effort to increase overall powertrain efficiency in electric vehicles (EVs), designers and engineers begin by identifying the areas of greatest inefficiency. Improving the efficiency of areas with these "power leaks" will bring the greatest gains. While important improvements have been made in recent months, the motor in general, and power inverter switching inefficiencies in particular, have been a relatively large source of loss in EVs for years.

Why is Safety at the Core of Software-Defined Vehicles?
Why is Safety at the Core of Software-Defined Vehicles? Creating technology can be a complicated and time-consuming process. At LHP Engineering Solutions, we provide just that: solutions. We are a services and technology integrator with the skill and expertise to solve your functional safety issues. One way we provide our clients with solutions is to introduce them to our advisory management model, the Functional Safety Ecosystem, a six-part integrated model with the power to move your company beyond compliance. Safety is at the core of software-defined vehicles, but true functional safety demands more than a simple mechanistic attempt to fulfill compliance requirements; LHP’s Ecosystem applies a more powerful holistic approach.

What Are the Different Electric Vehicle Standards?
What Are the Different Electric Vehicle Standards? Introduction Electrification is a process that has been around for decades. The history of the electric vehicle (EV) extends as far back as the 19th Century, and the world has witnessed different waves of growth since then. The current growth in EV ownership suggests a new direction in modern transportation, one the industry hopes to take to the next level. OEMs have been introducing new electrified vehicles in their inventory, emphasizing that electrification is a prominent focus for the industry and will continue to be as the trend continues to grow. Governments and subject matter experts (SMEs) collaborate to develop electric vehicle standards, ensuring a dependable EV market with reduced risks and hazards. EV standards will be one of many determining factors that help companies prioritize safety and guarantee the reliability of their products. The industry must maintain compliance with EV standards—especially as these EV systems become more complex—to advance modern transportation safely.

What is HIL Testing?
What is HIL Testing? Introduction The phrase Hardware-In-the-Loop (HIL) refers to the process of testing a vehicle’s hardware by integrating it into a software environment and simulating different real-life scenarios for the hardware to react to. A vehicle’s components and subsystems interact with each other cooperatively, so the functionality of smaller components will affect how the entire vehicle operates entirely.

What is the Future of Autonomous Vehicles?
What is the Future of Autonomous Vehicles? Today’s vehicles are complex machines with intricate technology and advanced capabilities. As the industry continues to grow the electrification of vehicles, the goal will be to advance driver systems and software so that they achieve the requirements for product safety. The complete shift into a mass implementation of electric vehicles (EVs) forms the question of what the future of autonomous vehicles (AVs) looks like. Currently, an autonomous future would consist of augmenting the autonomous features already integrated into vehicles to the point of operating without human intervention. These autonomous features already provide different levels of driver assistance, which provides reassurance that vehicles will perform safely. Table of Contents What is Autonomy?

What is Competence Management in Functional Safety?
What is Competence Management? The term Competence Management is derived from the broader world of business at large. In the realm of automotive functional safety, there are many terms and methodologies that are shared with or are similar to, terms and processes that are utilized across all types of manufacturing and business. However, within the automotive realm, these terms are naturally scoped to the requirements of the automotive business. Not only do many of these methodologies govern how a product is developed and tested, but they can also apply to the selection, management, and skills development, of the people performing the work.

What are Electric Vehicle Subsystems and Their Interactions?
Introduction The automotive industry has made several monumental advancements in vehicular technology that have redefined the understanding of modern transportation while still achieving and maintaining the functional safety aspect of creating advanced products. One active example of an opportunity the industry is currently thriving toward is electrification. The development of electric vehicle (EV) products makes testing necessary to ensure the safety and quality of their performance. In addition, that establishes the importance of Electric Vehicle Subsystems and their interactions—understanding how the implementation of these different components affects the construction of larger electrified systems will allow for the overall EV development process to be more efficient.

What Critical Role does Master Data Have in Engineering and Functional Safety?
What Critical Role does Master Data Have in Engineering and Functional Safety? Introduction Master data has a critical role in product functional safety, guaranteeing organizational visibility, and operational efficiency. As data becomes more complex in the future, the need for master data in automotive will continue to increase. This blog is the second of a 3-part series focused on the importance of master data, the technical architecture of master data systems, and the trade-offs and constraints that come with building these systems, ultimately proposing what a proper master data plan looks like, which can help organizations achieve growth and success. The content in each blog is centralized around the main topics from LHP’s DAS Master Data webinar panel that we held this past June:
