Process and device for indicating braking power or delay in cars
First Claim
1. A process for indicating a braking intensity of a vehicle to a driver of a following vehicle, comprising:
- generating a signal which corresponds to a level of deceleration of the vehicle,displaying lighted areas on at least two brake lights mounted side by side,controlling the lighted areas based upon said signal to vary the positions of said lighted areas to correspond to the level of deceleration, said variation of the lighted areas simulating at least one secondary visual signal directly perceived as a change in the level of deceleration by the driver of the following vehicle, said variation of the lighted areas comprising at least one of;
(a) moving the lighted areas upward as the level of deceleration increases;
(b) moving the lighted areas downward as the level of deceleration decreases;
(c) moving the lighted areas apart from each other as the level of deceleration increases; and
(d) moving the lighted areas toward each other as the level of deceleration decreases.

Abstract
The invention relates to a process and an arrangement for indicating the braking intensity or the deceleration of a vehicle. A signal generating device generates a signal corresponding to a deceleration of the vehicle, or a brake pedal force of the driver. An indicating device, which has at least two brake lights, indicates braking information assigned to the respective signal and a controller controls the indicating device on the basis of the signal provided by the signal generating device. The indicating device outputs various signals which correspond to various respective levels of braking intensity. The braking signal information is provided in a detailed form which does not have to be learned separately but which can be perceived directly by the driver based on knowledge already stored in the driver'"'"'s subconscious from normal driving operation and experience.

13. Arrangement for indicating a braking intensity of a vehicle to a driver of a following vehicle, said arrangement comprising:
-
a signal generating device which generates a signal corresponding to a level of deceleration of the vehicle, at least two brake lights with lighted areas mounted side by side, and a control device which controls the lighted areas based upon said signal to vary a position of said lighted areas to correspond to the level of deceleration, said variation of the lighted areas simulating at least one secondary visual signal directly perceived as a change in the level of deceleration by the driver of the following vehicle, said variation of the lighted areas comprising at least one of; (a) moving the lighted areas upward as the level of deceleration increases; (b) moving the lighted areas downward as the level of deceleration decreases; (c) moving the lighted areas apart from each other as the level of deceleration increases; and (d) moving the lighted areas toward each other as the level of deceleration decreases. - View Dependent Claims (14, 15, 16, 17, 18)

19. A method for visually signaling a change in a level of deceleration of a vehicle to a driver of a following vehicle via at least two brake lights mounted side by side and having lighted areas which are variable in size and position, said method comprising the act of:
-
varying at least the position of said lighted areas to correspond to the level of deceleration, said variation of the lighted areas comprising at least one of; (a) moving the lighted areas upward as the level of deceleration increases; (b) moving the lighted areas downward as the level of deceleration decreases; (c) moving the lighted areas apart from each other as the level of deceleration increases; and (d) moving the lighted areas toward each other as the level of deceleration decreases. - View Dependent Claims (20, 21)

22. An arrangement for visually signaling a change in a level of deceleration of a vehicle to a driver of a following vehicle, said arrangement comprising:
-
at least two brake lights mounted side by side and having lighted areas which are variable in size and position; and a control device controllingly coupled to said at least two brake lights to vary at least one of the size and the position of said lighted areas to correspond to the level of deceleration, said variation of the lighted areas comprising at least one of; (a) moving the lighted areas upward as the level of deceleration increases; (b) moving the lighted areas downward as the level of deceleration decreases; (c) moving the lighted areas apart from each other as the level of deceleration increases; and (d) moving the lighted areas toward each other as the level of deceleration decreases. - View Dependent Claims (23, 24)
