Increasing the Accuracy of the Electronic Control Units’ Adjustment in Modern Vehicles Parts to Ensure Their Reliability and Safety

Abstract

AbstractIn this article we investigated the problem of safety of modern vehicles. We selected the anti-lock braking system (ABS), because it contributes significantly to ensuring vehicle's active safety. Since vehicle safety on the road during emergency braking largely depends on this system’s correct functioning, it is important that it works correctly. Various manufacturers offer ABS’s execution either in a universal form suitable for a wide range of vehicle brands and vehicle classes, or in a unique one designed for a specific model. In the first case, it is necessary to pre-configure the component using the parameterization of the controller included in it. In this regard, the goal of the article was formulated - to develop a mechanism that accelerates the process of parameterizing the ABS’s electronic control unit (ECU), produced as a universal platform, and eliminates operator errors during its implementation. Developed program module solves this goal by reading vehicle parameters’ values from the file and sending them to ECU. Then the speed and accuracy of the block parameterization increases, and at the same time, it becomes possible to use one component on a universal platform when assembling a wide range of models and different types of vehicles. This simultaneously ensures the unification of components and small batch or even individual production in conditions of conveyor assembly. The algorithm underlying the proposed software module, in contrast to the software of the ABS’s manufacturer, allows for selective parameterization. This is especially important in real life conditions, since not all parameters set by the manufacturer are used in a particular vehicle model. It is also important in the situation when updating the values of individual parameters in the case of repeated parameterization of the electronic control unit in the service center, caused by the detection of errors in the previously recorded values.KeywordsActive safetyAnti-lock braking systemTruckParameterizationElectronic control unit
