Synop­sys ‘Lu­cidDrive’ of­fers de­sign and anal­y­sis tools for au­to­mo­tive light­ing

Auto components India - - COVER STORY - Anusha B

The US-head­quar­tered Synop­sys, the em­bed­ded so­lu­tion provider, ad­vances the vir­tual sim­u­la­tion of adap­tive head­lights with its new ver­sion of ‘Lu­cidDrive’ soft­ware. The soft­ware helps an­a­lyse the head­light’s per­for­mance dur­ing dy­namic driv­ing con­di­tions. The com­pany pro­vides var­i­ous so­lu­tions and the key to its suc­cess lies in the 5-pronged ad­van­tages: Speed and ac­cu­racy, safety, cost ef­fec­tive­ness, bet­ter prod­uct and easy de­sign.

“We give com­plete de­vel­op­ment chain of soft­ware so­lu­tions. We have sys­tems in place which have all the fea­tures to eval­u­ate au­to­mo­tive light­ing. We have spe­cialised tools for head lamps, sig­nal lamps among oth­ers which re­spond very fast on the chang­ing traf­fic con­di­tions. Our re­sponse time is 10 times faster. The prod­uct en­dorses safety as all the se­quen­tial steps are taken care with var­i­ous it­er­a­tions for the end-prod­uct to meet the stan­dards. Our so­lu­tion is also cost ef­fec­tive dis­count­ing mul­ti­ple pro­to­type mod­els. The prod­uct will be oneup in the mar­ket if right mix of sim­u­la­tion tech­niques are car­ried out and our dig­i­tal tool box does that tak­ing on new tasks fer­vently. Pre­ci­sion is the ut­most part in the au­to­mo­tive light­ing and we have specailsed tools for engi­neers to op­ti­mise the de­sign with­out com­pro­mis­ing the vi­tal needs,” An­dreas Bielawny, Man­ager CAE, Op­ti­cal So­lu­tions Group, Synop­sys Inc., told Auto Com­po­nents In­dia. The com­pany pro­vides soft­ware so­lu­tions for tier-1 and tier- 2 sup­pli­ers with its op­ti­cal pro­grammes. It has a small op­ti­cal di­vi­sion which takes care of all these needs. The soft­ware provider pre­dom­i­nantly works in ‘build to print’ style but the com­pany has the ca­pa­bil­ity to sug­gest the de­sign in­puts on re­quest.

The ‘Lu­cidDrive’ soft­ware is a night driv­ing sim­u­la­tion soft­ware which gives em­pha­sis on light dis­tri­bu­tion in the dy­namic en­vi­ron­ment. It gives vir­tual sim­u­la­tion of head­light road per­for­mance in dy­namic traf­fic sce­nar­ios. It in­cludes mul­ti­ple ve­hi­cles in night-driv­ing sce­nar­ios, each pro­grammed with dif­fer­ent char­ac­ter­is­tics and ve­loc­i­ties to en­hance re­al­ism. It has in­tel­li­gent driver model based on which the high ac­cu­racy cal­cu­la­tions of traf­fic flows and pat­terns are

cal­cu­lated. The user de­fined pa­ram­e­ters like ve­hi­cle speed, ac­cel­er­a­tion, de­cel­er­a­tion and brak­ing ca­pa­bil­i­ties are taken care with this model. Au­to­matic lane chang­ing ma­neu­vers are ex­pe­dited. Cus­tomised ve­hi­cle be­hav­iours can also be scripted with the sup­port of this soft­ware. The com­pany has a li­brary of road scenes and the sim­u­la­tions are taken care of with the help of this.

Lu­cidDrive prod­ucts pro­vide a com­plete set of de­sign and anal­y­sis tools for au­to­mo­tive light­ing. With ded­i­cated al­go­rithms op­ti­mized for au­to­mo­tive ap­pli­ca­tions, the soft­ware fa­cil­i­tates the de­sign of au­to­mo­tive for­ward, rear and sig­nal light­ing, and re­flec­tors and lenses. In ad­di­tion, the Lu­cidDrive tool pro­vides night-driv­ing sim­u­la­tions that gen­er­ate re­al­is­tic light­ing scenes in real time, which al­low de­sign­ers to quickly and ac­cu­rately eval­u­ate beam pat­terns of ve­hi­cle head­lamps prior to ex­pen­sive fab­ri­ca­tion and test­ing.

By sim­u­lat­ing chang­ing driv­ing con­di­tions and in­di­vid­ual ve­hi­cle be­hav­iours, the traf­fic sit­u­a­tion fea­ture in the sim­u­la­tion tool can ef­fec­tively an­a­lyse Adap­tive Front­light­ing Sys­tem (AFS) head­lights, which must adapt the light dis­tri­bu­tion, de­tect and il­lu­mi­nate ob­sta­cles and au­to­mat­i­cally mask out the high beam to pre­vent glare for on­com­ing ve­hi­cles.

“Vir­tual night-driv­ing sim­u­la­tions are gain­ing im­por­tance for new head­light types such as AFS, where it is crit­i­cal to val­i­date beam pat­terns that must re­spond to chang­ing driv­ing con­di­tions and driver be­hav­ior,” Ge­orge Bayz, Vice Pres­i­dent and Gen­eral Man­ager of Synop­sys’ Op­ti­cal So­lu­tions Group, said. The Lu­cidDrive Traf­fic Sim­u­la­tion fea­ture demon­strates how tech­ni­cal ad­vances in night­driv­ing sim­u­la­tions can help de­sign­ers as­sess and im­prove AFS ca­pa­bil­i­ties.

AFS car­ries with it a lot of im­por­tant as­pects. The way it is de­signed has re­duced a lot of com­plex­i­ties which was spot­ted in the tra­di­tional lamps. Even in the com­pli­cated elec­tronic sys­tems with mul­ti­ple LEDs, AFS has the ca­pa­bil­ity to dim the LED on en­coun­ter­ing daz­zling, sat­is­fy­ing the com­pli­cated and so­phis­ti­cated pre­ci­sion re­quire­ment. It is con­nected with Mat­lab and Simulink through which the cus­tomers can change the set­tings for mul­ti­ple in­puts. These tech­nolo­gies will soon reach the In­dian mar­ket also. Given In­dia is cost sen­si­tive, the sim­u­la­tion provider stated, cost op­ti­mi­sa­tion in the pro­duc­tion chain should be taken for­ward. To high­light, the light man­u­fac­tur­ers like Var­roc are com­ing up with low cost LEDs driv­ing in cost op­ti­mi­sa­tion in their pro­duc­tion chain.

“The soft­ware pro­vided by us works for all light sources. De­pend­ing on the qual­ity of the model and the in­for­ma­tion we have, pre­cise pre­dic­tion can be wit­nessed. In­dian mar­ket has emerged as one of the fastest de­vel­op­ing mar­kets. Not only the pre­mium seg­ment be­holds the LED, even the small seg­ment has started ex­pe­ri­enc­ing the LED-moves. It is def­i­nitely not a sur­prise if the do­mes­tic mar­ket will be LED-driven in 5-6 years. The mar­ket reck­ons the same and all the man­u­fac­tur­ers are mar­ket-ready and poised. Our Unique Value Propo­si­tion is that we pro­vide cus­tomers with a soft­ware with be­spoke fea­tures where a lit­tle bit of pro­gram­ming could help them ar­rive at their specifics with­out let­ting out their trade se­crets,” Bielawny said.

In in­dia, Synop­sys has R&D cen­tres in Noida, Delhi, Ben­galuru, Hy­der­abad, and Mum­bai. It does en­gi­neer­ing and de­sign­ing works here but there is no op­ti­cal di­vi­sion in In­dia. “We are the mar­ket lead­ers now and need to sus­tain this po­si­tion. All the up­com­ing tech­nolo­gies in the au­to­mo­tive light­ing can never hud­dle the op­ti­cal di­vi­son as this forms the base and we are the fore­run­ners. We guar­an­tee that our soft­ware will give all the nec­es­sary re­sults in one mock-up which was once tak­ing a week or more. We try to em­pha­sise this strength and con­tinue to be the leader,” he said.
