You can read that blog by clicking <a href=\"https:\/\/blogs.sw.siemens.com\/thought-leadership\/generative-design-for-autonomous-vehicles\/\">here<\/a>.<\/p>\n\n\n\n<p>In brief, generative design takes system definitions and\nrequirements as input and generates architectural proposals for the logic,\nsoftware, hardware, and networks of the vehicle\u2019s electrical and electronic\nsystems using rules-based automation. These design rules can capture company\nknowledge and the experience of veteran engineers, integrating this IP into\neach synthesized design. Furthermore, automated design synthesis accelerates\nthe engineering of various electrical systems, and enables rapid iteration to\narrive at optimized designs. <\/p>\n\n\n\n<p>These capabilities will allow engineers to manage the\ninherent complexity of autonomous vehicle design more effectively, reducing\nerrors related to manual data entry, and accelerating design iteration to\nproduce better self-driving vehicle platforms. Such capabilities will prove\ncritical to the development of these advanced vehicle platforms.<\/p>\n\n\n\n<p>Self-driving vehicles, however, are still years from mainstream viability. As self-driving technology continues to develop, the automotive industry is undergoing another upheaval: electrification (figure 1). Electric vehicle (EV) sales have grown tremendously over the last decade. According to the International Energy Agency\u2019s Global EV Outlook (2019), the global stock of hybrid and electric passenger vehicles eclipsed 5 million in 2018. This was a 63% increase compared to the previous year. Access to electric vehicle charging points has also improved, with an estimated 5.2 million worldwide.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"2462\" height=\"1642\" src=\"https:\/\/blogs.sw.siemens.com\/wp-content\/uploads\/sites\/24\/2020\/02\/Fig-1-new-transportation-small.jpg\" alt=\"\" class=\"wp-image-5\" srcset=\"https:\/\/blogs.sw.siemens.com\/wp-content\/uploads\/sites\/24\/2020\/02\/Fig-1-new-transportation-small.jpg 2462w, https:\/\/blogs.sw.siemens.com\/wp-content\/uploads\/sites\/24\/2020\/02\/Fig-1-new-transportation-small-300x200.jpg 300w, https:\/\/blogs.sw.siemens.com\/wp-content\/uploads\/sites\/24\/2020\/02\/Fig-1-new-transportation-small-1024x683.jpg 1024w, https:\/\/blogs.sw.siemens.com\/wp-content\/uploads\/sites\/24\/2020\/02\/Fig-1-new-transportation-small-768x512.jpg 768w, https:\/\/blogs.sw.siemens.com\/wp-content\/uploads\/sites\/24\/2020\/02\/Fig-1-new-transportation-small-1536x1024.jpg 1536w, https:\/\/blogs.sw.siemens.com\/wp-content\/uploads\/sites\/24\/2020\/02\/Fig-1-new-transportation-small-2048x1366.jpg 2048w, https:\/\/blogs.sw.siemens.com\/wp-content\/uploads\/sites\/24\/2020\/02\/Fig-1-new-transportation-small-1110x740.jpg 1110w\" sizes=\"auto, (max-width: 2462px) 100vw, 2462px\" \/><figcaption>Figure 1: Many expect electric vehicles to take over as the primary mode of personal transportation and mobility in the future. <\/figcaption><\/figure>\n\n\n\n<p>As EVs continue to close the gap to IC vehicles technologically,\ncountries around the world are announcing regulations to incentivize or even\nrequire the use of electric powertrains in new vehicles. Facing regulatory\npressure and recognizing the opportunity presented by the EV market, the\nautomotive industry has responded. EV startups have flooded the market and\nnearly every major automotive brand has announced plans for all-electric\nvehicle lineups. Generative design also has an important role to play in the\ndevelopment of these new electric vehicles.<\/p>\n\n\n\n<p>Startup EV companies and long-standing automotive brands\nwill need to account for the unique challenges of electric vehicle design.\nToday, vehicles of all types incorporate thousands of electrical and electronic\ncomponents that enable vehicle features and critical functionality. Each of\nthese electrically powered systems places additional loads on the vehicle\nbattery pack. Because all-electric\nvehicles do not have the support of a supplemental source of power, such as an\nICE, the battery is responsible for providing power to each and every vehicle\nsystem, large and small. <\/p>\n\n\n\n<p>As\na result, the number and sophistication of the electronic features on an\nelectric vehicle has a direct effect on the drive range and performance of the\nvehicle. ADAS systems often incorporate cameras, radar, and ultrasonic sensors\nto enable lane departure warning systems, automatic braking, and more. These\nsystems are a constant drain on the battery as they are always active. <\/p>\n\n\n\n<p>To\nenhance the efficiency of the electrical and electronic systems, and thus drive\nrange, engineers will need to perform architecture and tradeoff analyses to\ninvestigate architectural proposals. The tradeoff &nbsp;analyses for an EV will need to account for\nhundreds of components and millions of signals while optimizing function\nlocations, network latency, error rates and more.<\/p>\n\n\n\n<p>Other engineering challenges result from the high voltage transmission lines that bring power to the electric motor driving the car. These lines require additional design guidelines to ensure they are bundled and routed appropriately (figure 2). Electric vehicles also require extensive testing and validation to ensure safety while maximizing the drive range and performance of the vehicle. Manufacturers will need to incorporate simulated and real-world testing into their electric vehicle programs to ensure that vehicles can meet both industry safety standards and performance targets.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"667\" src=\"https:\/\/blogs.sw.siemens.com\/wp-content\/uploads\/sites\/24\/2020\/02\/AdobeStock_198399970_Auto_HV_LV_Harness_Installation_MotorDriveUnit1_tcm27-55381.jpg\" alt=\"\" class=\"wp-image-8\" srcset=\"https:\/\/blogs.sw.siemens.com\/wp-content\/uploads\/sites\/24\/2020\/02\/AdobeStock_198399970_Auto_HV_LV_Harness_Installation_MotorDriveUnit1_tcm27-55381.jpg 1000w, https:\/\/blogs.sw.siemens.com\/wp-content\/uploads\/sites\/24\/2020\/02\/AdobeStock_198399970_Auto_HV_LV_Harness_Installation_MotorDriveUnit1_tcm27-55381-300x200.jpg 300w, https:\/\/blogs.sw.siemens.com\/wp-content\/uploads\/sites\/24\/2020\/02\/AdobeStock_198399970_Auto_HV_LV_Harness_Installation_MotorDriveUnit1_tcm27-55381-768x512.jpg 768w\" sizes=\"auto, (max-width: 1000px) 100vw, 1000px\" \/><figcaption>Figure 2: The high-voltage wiring needed in an electric powertrain requires special considerations during design. <\/figcaption><\/figure>\n\n\n\n<p>Most companies have little experience tackling the\nchallenges related to electric vehicle design. Indeed, most of the companies\nattempting to do so are startups or companies from other industries seeking to\nenter a traditionally impenetrable market. These companies lack\nindustry-specific experience and the engineering resources to brute force their\nway through the complexities of electric vehicle design. Even the major\nautomotive OEMs will face problems that their legacy design flows are\nill-equipped to handle.<\/p>\n\n\n\n<p>This will be true especially as companies move their electric\nvehicle projects from research, development, and one-off prototyping into\nfull-scale production. The electrical and electronic systems will need to be\noptimized for cost, weight, and power consumption while adhering to the\nstringent safety requirements prevalent in the automotive industry. To compete,\nthese companies will need a new design methodology that enables young engineers\nto design accurate and optimized systems, which can only be done by capturing\nthe experience and knowledge of veteran engineers. They will need generative\ndesign.<\/p>\n\n\n\n<p>To read more, please check out <a href=\"https:\/\/www.plm.automation.siemens.com\/global\/en\/topic\/ev-electrical-systems-white-paper\/67407\" target=\"_blank\" rel=\"noopener\">Generative Design for EV Electrical Systems<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In a previous blog, I covered the benefits that generative design can bring to bear on the development of an&#8230;<\/p>\n","protected":false},"author":69483,"featured_media":16,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"spanish_translation":"","french_translation":"","german_translation":"","italian_translation":"","polish_translation":"","japanese_translation":"","chinese_translation":"","footnotes":""},"categories":[85,1],"tags":[112,99,13,113],"industry":[42,43,44,46,45],"product":[],"coauthors":[],"class_list":["post-4","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-ebook","category-news","tag-electric-vehicles","tag-electrical-systems-engineering","tag-generative-design","tag-today-meets-tomorrow","industry-automotive-transportation","industry-automotive-oems","industry-automotive-suppliers","industry-motorcycles-bicycles-parts","industry-trucks-buses-specialty-vehicles"],"featured_image_url":"https:\/\/blogs.sw.siemens.com\/wp-content\/uploads\/sites\/24\/2020\/02\/Car-Digital-UI-smart-3D-car-hands-holding-Adobe-194992198-small-scaled.jpg","_links":{"self":[{"href":"https:\/\/blogs.sw.siemens.com\/ee-systems\/wp-json\/wp\/v2\/posts\/4","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/blogs.sw.siemens.com\/ee-systems\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/blogs.sw.siemens.com\/ee-systems\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/blogs.sw.siemens.com\/ee-systems\/wp-json\/wp\/v2\/users\/69483"}],"replies":[{"embeddable":true,"href":"https:\/\/blogs.sw.siemens.com\/ee-systems\/wp-json\/wp\/v2\/comments?post=4"}],"version-history":[{"count":5,"href":"https:\/\/blogs.sw.siemens.com\/ee-systems\/wp-json\/wp\/v2\/posts\/4\/revisions"}],"predecessor-version":[{"id":15,"href":"https:\/\/blogs.sw.siemens.com\/ee-systems\/wp-json\/wp\/v2\/posts\/4\/revisions\/15"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/blogs.sw.siemens.com\/ee-systems\/wp-json\/wp\/v2\/media\/16"}],"wp:attachment":[{"href":"https:\/\/blogs.sw.siemens.com\/ee-systems\/wp-json\/wp\/v2\/media?parent=4"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/blogs.sw.siemens.com\/ee-systems\/wp-json\/wp\/v2\/categories?post=4"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/blogs.sw.siemens.com\/ee-systems\/wp-json\/wp\/v2\/tags?post=4"},{"taxonomy":"industry","embeddable":true,"href":"https:\/\/blogs.sw.siemens.com\/ee-systems\/wp-json\/wp\/v2\/industry?post=4"},{"taxonomy":"product","embeddable":true,"href":"https:\/\/blogs.sw.siemens.com\/ee-systems\/wp-json\/wp\/v2\/product?post=4"},{"taxonomy":"author","embeddable":true,"href":"https:\/\/blogs.sw.siemens.com\/ee-systems\/wp-json\/wp\/v2\/coauthors?post=4"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
