    Abstract: A brake disc for motor-vehicle disc brakes, includes a body with a hub and two opposite annular planar faces, wherein at least one of these faces is formed with one or more lines defining a surface irregularity, in the form of grooves or ribs, which extend between a radially inner edge and a radially outer edge of the respective face, so as to substantially cover the entire radial extension of the face. A height of the surface irregularity along said lines is less than 0.30 mm, so that during use, the lines defining the surface irregularity disappear, due to wear of the respective face, after an initial fraction of the life of the brake disc. During this initial stage, the lines defining the surface irregularity reduce the time necessary to obtain a bedding of the disc brake with respect to a case of a brake disc devoid of the lines.

    Abstract: Unit with longitudinal beam and front plate for a motor-vehicle front structure, comprising a longitudinal beam in the form of a hollow profile and a front plate rigidly connected to a front end of said longitudinal beam. The longitudinal beam comprises a first beam element defining an upper wall, a lower wall and a first side wall of the longitudinal beam and a second beam element having a wall defining a second side wall of the longitudinal beam. The front plate has a rear face facing towards the longitudinal beam to which there are welded a first flange and a second flange which are separate from each other, for connecting the front end of the longitudinal beam. The first flange is a C-shaped bracket with an upper wall, a lower wall and a side wall respectively welded to the upper wall, the lower wall and the first side wall defined by said first beam element. The second flange is an L-shaped bracket, with a first wall welded to the rear face of the front plate and a second wall facing towards said second side wall defined by said second beam element. The above mentioned welds are electric spot welds. The two flanges may have different thickness.

    Abstract: An electronic control system for a motor vehicle comprising an automatic transmission operable to assume different operating modes, comprising a reverse mode, a neutral mode, a park mode, a drive mode and a manual mode, in response to a manual operation of a selector with at least one control switch and mounted to assume a stable central neutral position when the selector is not operated, and to be movable in opposite selection directions from the stable central neutral position to reach two instable end-of-travel selection positions arranged on opposite sides of the stable central neutral position. The automotive electronic control system is configured to detect operation of the selector and of the control switch and cause the transmission to switch from drive mode to reverse mode in response to operation of the selector in a first selection direction and with the control switch pressed, and from reverse mode to drive mode in response to operation of the selector in a second selection direction opposite to the first selection direction and with the control switch pressed.
