RU2527596C1 - Control over carrier back-blow - Google Patents

Abstract

FIELD: transport.

SUBSTANCE: in compliance with this method, distance is measured proceeding from the analysis of magnetic field structure of magnetic strip built in roadway. Back-blow magnitude is calculated as the difference between initial distance from magnetic strip to transducer and current distance.

EFFECT: higher accuracy of control and reliability, efficient operation under whatever ambient conditions.

Description

The invention relates to training simulators for learning to drive a vehicle and can be used to test driving skills while passing qualification exams for obtaining a driver’s license.

A known method of controlling the rollback of a vehicle (patent No. 2308094), comprising a rollback measuring unit installed on the site of the race track and / or vehicle and containing an ultrasonic or optical sensor for measuring the value of the rollback. Moreover, the rollback value is determined by calculating the difference between the base distance (the distance from the measuring unit to the rear dimension of the vehicle after stopping) and the minimum measured distance when rolling back.

The disadvantages of this method are:

- the dependence of the work on weather conditions;

- the presence of additional measuring equipment at the site of the race track;

- possible deterioration of measurement accuracy depending on the position of the vehicle.

The objectives of this invention are:

- improving the accuracy of control of the rollback of the vehicle during the exercise "slide";

- the possibility of full-fledged work, regardless of weather conditions;

- improving the reliability of the system due to the lack of additional measuring equipment.

The specified technical result is achieved by the fact that the method of controlling the intersection consists in measuring the magnetic field from magnetic strips mounted in the asphalt sheet.

The method is illustrated in figure 1. The magnetic strip is a recessed in the roadway group of sequentially stacked with the ends to each other magnets with the same direction of the magnetic field vector. Thus, the structure of the magnetic field along the entire magnetic strip is the same and uniform.

A three-component magnetic field sensor mounted on a vehicle determines the direction and modulus of the magnetic field vector, which, minus the external field, including the Earth’s natural field, corresponds to the field from the magnetic strip. Depending on the distance of the sensor from the magnetic strip (L), the direction (angle relative to the horizon) and the magnetic field vector module change during the movement. The rollback value in this case is determined by calculating the difference between the initial distance from the sensor to the magnetic strip (at the time the car stopped) and the current distance.
