It's news time at CEMB. Providing its customers with a complete product portfolio is the objective behind the recent acquisition of M&B Engineering, announced last July, an important Italian manufacturing company active in the field of tire and garage equipment. Through this acquisition CEMB aims to complete its offer, traditionally made up of wheel balancing machines and vibration analysis, with a complete range of professional tire changers, designed and produced at the headquarters of M&B Engineering. A complete range of equipment for tire dealers and garages, therefore, able to meet the standards of quality and technological innovation that are now so common in the aftermarket sector. As far as technology is concerned, the economic and industrial landscape is currently evolving at an unprecedented pace: it is therefore increasingly important to keep up with the times, supplying products that can meet increasingly sophisticated needs.

From this point of view, CEMB has recently received an important recognition: its Argos wheel alignment system - a touch-less wheel alignment machine equipped with a 3D scanner system, which allows you to measure camber angle and toe in just 5 seconds - has been included in the "Top 20 tools" list, drawn up by the American magazine Motor Magazine.

As Technology evolves relentlessly, no area of life is spared. The automotive sector, of course, is no exception, reaching goals that were once considered unimaginable. If the long-term objective for the sector is the development of fully autonomous vehicles, able to independently carry out all the necessary operations to drive the vehicle through a series of integrated tools, the automotive sector has already developed a series of sophisticated systems that can assist drivers. ADAS - an acronym for Advanced Driver Assistance System - include devices such as twilight sensors that automatically manage the vehicle’s lights, adaptive cruise control, which adjusts driving speed according to traffic, parking sensors, automatic emergency braking, lane change warning and automatic signage recognition, and so on.

The main objective behind ADAS systems is to increase the level of road safety, in line with recent European regulations aimed at reducing the number of road accidents by 2020. As the European Commission stated in a communication: "Autonomous vehicles will change our lives, just as steam trains and cars did in the past, and they will define the future of road transport, with the possibility of significantly reducing its costs. Such vehicles could create new business opportunities, services and innovative ways of responding to the growing demand for mobility of both people and goods. Once the obvious initial problems have been properly addressed and solved, autonomous vehicles could significantly improve road safety, as an estimated 94% of accidents are caused by human error". The EU's objective in this respect, the object of a recent preliminary agreement, is to make the use of a set number of ADAS mandatory in new type-approved vehicles from 2022 onwards.

Cars equipped with autonomous driving systems are divided into 6 levels, as established by the Society of Automotive Engineers (SAE): starting from level 0, which indicates cars equipped with some safety systems able to intervene in some driving situations but in no case taking control of the vehicle, up to level 5, which indicates a vehicle that can run autonomously – i.e. without the need for human intervention - on any type of road and in any condition. At present, most vehicles on the road are equipped with systems ranging from level 0 to level 2: systems such as adaptive speed control, assisted braking and collision avoidance and emergency braking allow the vehicle to manage acceleration and braking, although direction and traffic control remain under the exclusive control of the driver.

Most modern cars are now equipped with a series of devices such as cameras, radar sensors, lidars and ultrasonic detectors that allow the driver to get a complete overview of what is happening outside the vehicle, in an attempt to avoid collisions and accidents. It goes without saying that, in order to guarantee the correct functioning of these devices and to avoid false alarms that could compromise their efficiency, sensor calibration is a fundamental procedure, which must be carried out not only when one of the devices is damaged, but also when one of the components in which one of these devices is integrated suffers damage – however slight that may be -.

Quite clearly, it is important for garage operators to work quickly and effectively on these systems, thanks also to the help of suitable equipment. The calibration (or re-calibration) of ADAS devices is in fact mostly done inside workshops, in what is called static mode, through the use of calibration panels that vary depending on the vehicle brand. Moreover, panels must be installed taking into account the direction of travel defined by the thrust angle, a procedure that can be particularly complex and with a high risk of human error, if carried out manually. Another fundamental procedure to be carried out before recalibration is the verification of the vehicle’s set up.

In order to simplify this type of operation, CEMB has launched its new ADAS CCD KIT on the market, which promises to streamline ADAS recalibration procedures. The new kit is presented as a combination between a wheel alignment system and a support for the ADAS and ACC calibration panels. Operating it is rather simple: after checking the alignment, the front wheel detectors are placed on the calibration bar of the ADAS panel support by means of universal adapters - which makes it possible to use these instruments on any calibration panel -; the detectors, instead, are left on the rear wheels. Thanks to the use of a dedicated software, also included in the kit, the support of the ADAS calibration panels is guided into position by a special interactive process on the screen. The CEMB kit, as indicated by the company, allows to identify the thrust axis in a few moments, thus allowing the CCD system to provide the user with a real-time indication of the relative position between the thrust axis and the ADAS/ACC calibration structure.
