Co znamen\u00e1 ADAS?<\/h2>\n

Advanced Driver Assistance Systems (ADAS) jsou vysp\u011bl\u00e9 asisten\u010dn\u00ed syst\u00e9my, kter\u00e9 pom\u00e1haj\u00ed zv\u00fd\u0161it bezpe\u010dnost a pohodl\u00ed p\u0159i \u0159\u00edzen\u00ed. P\u0159\u00edkladem jsou parkovac\u00ed asistenti, kte\u0159\u00ed zabra\u0148uj\u00ed po\u0161kozen\u00ed vozidla p\u0159i parkov\u00e1n\u00ed, nebo automatick\u00e9 sv\u011btlomety, kter\u00e9 zap\u00ednaj\u00ed sv\u011btlomety v z\u00e1vislosti na sv\u011bteln\u00fdch podm\u00ednk\u00e1ch. <\/p>\n

Rozd\u00edl mezi DAS a ADAS<\/h2>\n

Existuj\u00ed dv\u011b z\u00e1kladn\u00ed kategorie asisten\u010dn\u00edch syst\u00e9m\u016f \u0159idi\u010de: DAS (Driver Assistance System) a ADAS. Term\u00edn DAS zahrnuje p\u016fvodn\u00ed asisten\u010dn\u00ed syst\u00e9my, u nich\u017e se nezaznamen\u00e1v\u00e1 situace mimo vozidlo. Jedn\u00e1 se nap\u0159\u00edklad o tempomat, kter\u00fd reguluje rychlost bez ohledu na dopravn\u00ed situaci. Pod pojmem ADAS se naopak skr\u00fdvaj\u00ed syst\u00e9my, kter\u00e9 zohled\u0148uj\u00ed dopravn\u00ed situaci a reaguj\u00ed na ni, a pat\u0159\u00ed mezi n\u011b nap\u0159\u00edklad adaptivn\u00ed tempomat, kter\u00fd p\u0159izp\u016fsobuje rychlost vozidlu jedouc\u00edmu vp\u0159edu.
Jak funguje ADAS<\/p>\n

ADAS pracuje ve t\u0159ech f\u00e1z\u00edch:<\/h2>\n
    \n
  1. Shroma\u017e\u010fov\u00e1n\u00ed \u00fadaj\u016f: Senzory, jako jsou radar, ultrazvuk a LiDAR a tak\u00e9 kamery s vysok\u00fdm rozli\u0161en\u00edm sn\u00edmaj\u00ed okol\u00ed.<\/li>\n
  2. Zpracov\u00e1n\u00ed \u00fadaj\u016f: Data vyhodnocuje \u0159\u00eddic\u00ed p\u0159\u00edstroj.<\/li>\n
  3. Reakce: Syst\u00e9m generuje vizu\u00e1ln\u00ed, akustick\u00e9 nebo haptick\u00e9 v\u00fdstra\u017en\u00e9 sign\u00e1ly nebo aktivn\u011b zasahuje do \u0159\u00edzen\u00ed vozidla.
    Po\u017eadavky na ADAS<\/li>\n<\/ol>\n

    Vzhledem k tomu, \u017ee syst\u00e9m ADAS p\u0159istupuje p\u0159\u00edmo k syst\u00e9m\u016fm vozidla, jsou z\u00e1sadn\u00ed vysok\u00e9 po\u017eadavky na funk\u010dn\u00ed bezpe\u010dnost. Komponenty mus\u00ed b\u00fdt chr\u00e1n\u011bny proti poruch\u00e1m a mus\u00ed b\u00fdt spolehliv\u00e9. Velmi d\u016fle\u017eit\u00e1 je kvalita p\u0159enosu dat mezi senzory a \u0159\u00eddic\u00edmi jednotkami, proto\u017ee modern\u00ed syst\u00e9my vy\u017eaduj\u00ed velkou \u0161\u00ed\u0159ku p\u00e1sma a n\u00edzkou latenci. K tomu jsou nezbytn\u00e9 vysoce kvalitn\u00ed kabely a konektorov\u00e9 syst\u00e9my, kter\u00e9 p\u0159en\u00e1\u0161ej\u00ed sign\u00e1ly v p\u00e1smu GHz.<\/p>\n

    Trendy na trhu a ve v\u00fdvoji<\/h2>\n

    Trh ADAS velmi rychle roste a o\u010dek\u00e1v\u00e1 se, \u017ee do roku 2029 dos\u00e1hne objemu 86,14 miliardy USD d\u00edky pokroku v oblasti radar\u016f, LiDAR, kamer a ultrazvukov\u00fdch technologi\u00ed. Tento v\u00fdvoj je d\u00e1n popt\u00e1vkou po bezpe\u010dnosti a pohodl\u00ed ve vozidlech. Na trhu vedou regiony jako Severn\u00ed Amerika a asijsko-pacifick\u00e1 oblast. P\u0159edn\u00ed v\u00fdrobci investuj\u00ed do v\u00fdzkumu a v\u00fdvoje zna\u010dn\u00e9 prost\u0159edky a syst\u00e9my ADAS tak d\u00e1le zdokonaluj\u00ed a stanovuj\u00ed nov\u00e9 standardy.
