Device for indicating speed levels for motor vehicles
First Claim
Patent Images
1. 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.

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.

15. 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. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45)
