In modern automobile transport, the methodology of probabilistic estimates of the time between failures of automobiles, which has been developed over decades, is not used, and manufacturers do not include data on their reliability in the characteristics of automobiles. With their distribution of cars on flights and routes, the motor transport enterprises do not calculate the margin of their performance before repair or maintenance. The aim of this work is to substantiate automation methods for a comprehensive reliability assessment of a car and determine the residual life before setting up for repair or maintenance. It is proposed to use for these purposes statistical estimates of the operating time parameter between statements for repair or maintenance and their change as the vehicle develops a resource. A new service for the on-board local area network of vehicle has been developed to automatically monitor the performance margin. It is based on a joint automatic control of statements for repair or maintenance and calculation of vehicle operating time between them. The proposed control is intended to be implemented by means of the on-board local area network of the car and the information system for supporting the technical operation of cars at the motor transport enterprise.
For the transfer of road transport to unmanned driving, it is necessary to create not only technologies for automatic control of the movement of vehicles, but also technical measures to protect them from failures of components of unmanned vehicles. Such protection will ensure the development of monitoring the performance and operational properties of unmanned vehicles in combination with algorithms for the use of its results. The purpose of this work is to substantiate the methods of automation of control parameters of performance of unmanned vehicles and the construction of protective control algorithms of unmanned vehicles in the interests of technical operation. A new method of automatic control of parameters dependent on the technical condition, modes and operating conditions of vehicles is proposed. It is based on the simultaneous control of the parameters of the technical condition, mode and operating conditions of the tested component, the division of the ranges of possible changes in the parameters of the mode and conditions at narrow intervals, the formation of possible combinations of the intervals obtained and registration of the standards of the estimated parameter for each combination of intervals at the beginning of operation of an unmanned vehicle. The proposed method is intended for the implementation of the onboard local network of an unmanned vehicle.
