A vehicle driving assist apparatus has surrounding sensors which detect vehicle surrounding situations and driving assist systems which assist a driving operation of a driver, based on the vehicle surrounding situations. The vehicle driving assist apparatus determine whether the surrounding sensors malfunction. When the at least one electronic control unit determines that at least one of the surrounding sensors malfunctions, the vehicle driving assist apparatus determine operable driving assist systems and inoperable driving assist systems, and causes a display device to display both of a display indicating that at least one of the surrounding sensors malfunctions and a display indicating a list of the operable driving assist systems and the inoperable driving assist systems in a manner that the driver can realize which driving assist systems are operable and which driving assist systems are inoperable.
