日よけ is a more general term for sunshade or sun protection, often used for awnings, parasols, or sunshades in gardens. 日覆い specifically refers to a covering or screen, often for windows or vehicles.
ブラインド is a loanword for blinds, typically referring to slatted window coverings. 日覆い can include blinds but is broader, covering any sun-blocking screen.
Compound of 日 (hi, 'sun') and 覆い (ooi, 'covering'). The reading ひおい is a contraction of ひおおい.
