Abstract: An automotive adaptive cruise control system for a host motor vehicle configured to operate in at least two different operating modes comprising a first operating mode, in which a current speed of the host vehicle is controlled to maintain a cruise speed, and a second operating mode, in which the current speed of the host vehicle is controlled to maintain a cruise distance to a leading vehicle, wherein the system is configured to: detect approaching to a traffic light and determine a light signal emitted thereby, signal to the driver the presence of the detected traffic light and the determined light signal, if the traffic light emits a red or amber light signal, estimating a driver reaction time, determining a higher threshold distance and a lower threshold distance from the traffic light, and warning the driver of the host vehicle of the need to slow it down if, after the driver reaction time has elapsed: i) the host motor vehicle has not decreased its speed by more than a calibratable threshold, ii) the current speed of the host vehicle is higher than a minimum speed, iii) either the distance of the host vehicle from the traffic light is lower than the higher threshold distance and the light signal emitted by the traffic light is red, or the distance of the host vehicle from the traffic light is between the higher and lower threshold distances and the light signal emitted by the traffic light is amber, and iv) a service brake of the host vehicle is unoperated.

Abstract: A method controls a valve-control system for variable-lift actuation of the valves of an internal-combustion engine, in which the valve-control system includes, for each cylinder of the engine, a solenoid valve for controlling the flow of a hydraulic fluid in the system, and designed manner for determining a real temperature value of the hydraulic fluid. The method includes determining a deviation of performance of the solenoid valves due to a degradation of the characteristics of the hydraulic fluid with respect to nominal values thereof, and substituting for the real temperature value an equivalent temperature value consisting of a temperature value at which the hydraulic fluid having nominal characteristics would produce performance of the solenoid valves corresponding to the performance resulting from the deviation so that each solenoid valve is governed as a function of the equivalent temperature value.
