Embodiment Construction

[0025] exist figure 1 The emergency brake warning device described in has the form of a printed circuit 1 powered by the car's 12V battery 2, which includes a voltage regulation / stabilizer unit 3 for powering a dual type digital inertial sensor 5 and a microprocessor 6.

[0026] The inertial sensor 5 may be an ADXL202 sensor produced by ANALOG DEVICE (Paris, France). This sensor can provide data on acceleration or deceleration values ​​received on two perpendicular axes. In this application, only one of these axes is used, and this axis is referred to as the "active line" throughout the specification. The data provided by the inertial sensor 5 consists of digital values ​​provided every 56 milliseconds for this type of sensor. For the same acceleration value, these digital values ​​from the various sensors are usually different; this exact tolerance will be accounted for by the scaling operation described below.

[0027] To maximize the operation of the emergency brake warn...

Abstract

An emergency braking warning device includes a printed circuit (1) whereon are implanted a voltage regulator / stabiliser assembly (3), a two-way digital inertia sensor (5), a microprocessor (6) and power control elements (10, 11). The voltage regulator / stabiliser assembly (3) is connected to the vehicle battery and powers the two-way digital inertia sensor and the microprocessor (6). The microprocessor (6) is adapted to manage data coming from the digital sensor (5) and it is connected to the power control elements (10, 11) interposed on the circuits of the right (8) and left (9) flashers, to enable the triggering of the flashers (8, 9) when the programmed braking threshold is exceeded.

Description

technical field [0001] The invention relates to the field of general automotive equipment. More specifically it relates to a new device for activating the anti-collision lights of automobiles according to predetermined braking thresholds, it also relates to an original method of activating the anti-collision lights using this device, and a device capable of programming and calibrating said devices. Background technique [0002] Emergency brake warning devices using inertial sensors mounted on vehicles (cars, motorcycles or trucks) are known to automatically activate anti-collision lights according to a predetermined braking threshold to warn other drivers of potentially dangerous vehicle brakes. The drive system has been activated. [0003] In general, the known devices are not very satisfactory because of their structural complexity or lack of accuracy and reliability. [0004] In particular, application text DE-U-29617527 relates to a system that automatically provides a...
