Abstract
In a method and device for indicating speed levels of a motor vehicle, the speed as well as danger factors are transformed into parameters, which are combined. Their combination is compared with a threshold value, for possible actuation of an alarm, after modulation of the danger factors in accordance with a safety factor dependent on characteristics of the vehicle and of its driver.

Method of indicating operational conditions, including speed levels, in motor vehicles, comprising the steps of;
- deriving from a speed of a vehicle a first signal indicative of the speed;
- determining whether danger factors are present and if so, driving from each an additional signal of a nature similar to a nature of the first signal and having a predetermined value, modulating each additional signal in accordance with safety factors dependent on characteristics of the vehicle and on characteristics of a driver for the vehicle;
- combining the first signal with the modulated additional signals to obtain a combined value;
- comparing the combined value with a pre-determined threshold;
- and actuating an alarm in response to the comparison, when the value compared with the threshold exceeds the threshold.
Device for indicating operational conditions, including speed levels, in a motor vehicle, comprising;
- a speed circuit for deriving from a vehicle's speed an electrical signal having a value corresponding to the speed of the vehicle;
- means for determining whether danger factors are present and for deriving from each determined danger factor an electrical danger signal of a predetermined value corresponding to the respective danger factor;
- means for modulating each derived danger signal in accordance with a safety factor dependent on characteristics of the vehicle and on characteristics of a driver for the vehicle;
- means for combining the modulated electrical danger signals with the electrical signal corresponding to the vehicle's speed into a resilient value;
- a comparing circuit including a flip-flop relay for comparing the resultant value with a pre-determined threshold;
- and
- a warning system actuatable by the relay upon the comparison, for indicating a danger existing at the danger existing at the detected speed.
Apparatus for adjustably setting operational conditions of a device in a vehicle for indicating the vehicle's operation with respect to such conditions, the device having removable and interchangeable media for controlling corresponding speed and danger factors, the apparatus comprising;
- a console;
- means thereon for plugging onto the console a medium, removed from a device for controlling speed and danger factors for a vehicle;
- means on the console for simulating different speed and danger factors and correspondingly adjusting the controlling of the speed and danger factors;
- and
- means on the console for determining safety factors, dependent on characteristics of the vehicle and of a driver, and for correspondingly controlling the adjusting means.
