Abstract

Usage: to measure the force applied to the controls of vehicles. The essence of the utility model is that the steering wheel cover contains pressure sensors, analog-to-digital converters, while the pressure sensors are evenly placed on the surface of the steering wheel cover, and the electrical signals from the sensors enter the corresponding analog-to-digital converters, and the resulting digital codes are transferred to the device to register the received data. EFFECT: increased accuracy and universal use when receiving data on the pressure of the driver’s hands on various steering wheels. 1 ill.

Description

A device relates to methods or devices for measuring forces, for example, impact, work, mechanical power or torque, intended for special purposes (G01L 5/00), in particular for measuring the force applied to controls, for example vehicles (G01L 5 / 22). The measurement results obtained by the device can be used in scientific research in the field of ergonomics and the development of a methodology for the influence of road conditions on the behavior of drivers in order to improve road safety.

A device is proposed for obtaining digital data on the degree of pressure of the driver’s hands on the steering wheel of a vehicle in the form of a steering wheel cover, as well as for converting the received analog data into a digital code to collect information about the degree of such pressure when changing road conditions.

Known devices for measuring the force applied to the controls. A device for measuring the force applied to the control stick of an aircraft (USSR Author's Certificate No. 993061, G01L 5/22, 01/30/1983) contains a manual drive and a curved monorail with a gear rack connected to the drive and the recording device, and the monorail is designed so that the shape of the curve of its midline corresponds to a given trajectory of the handle. However, such a device does not allow to determine the pressure force of the driver’s hands on the controls of the trackless vehicle.

There is another device for measuring the force on the manual control lever of an aircraft (USSR Author's Certificate SU 1605723 A1, 12/20/2000), comprising a rocker connected to a force sensor and a movement mechanism, characterized in that, in order to increase the measurement accuracy, the rocker is made in in the form of a movable part and a fixed base pivotally connected to each other, and the force sensor is rigidly connected to the movable part of the rocker, the axis of rotation of which is combined with the axis of rotation of the manual control lever. However, such a device does not allow to obtain data on the pressure of the driver’s hands on the steering wheel of the vehicle.

Closest to the claimed technical solution is the Method of measuring the forces applied to the handles of the controls (USSR Author's Certificate SU (11) 1434284 (13) A1, G01L 5/22, G01L 5/16, 10/30/1988). The technical solution includes an even number of sensors placed at an equal distance from each other along the perimeter of the handle of the control, and in the process of measuring a pair of sensors is selected that lie at the ends of one of the diameters of the cross section of the handle with the maximum signal difference, which is used to judge the magnitude of the handle movement force, and the magnitude of the smaller output signal judges the magnitude of the grip force of the handle. However, this technical solution does not allow to determine the grip force of the driver of the standard steering wheel of the vehicle due to the fact that this solution is permanently mounted on a certain control handle, is not universal and does not allow to determine the force of the pressure on the steering wheels of various vehicles.

To eliminate these disadvantages allows the proposed device in the form of a cover for the steering wheel with pressure sensors.

The purpose of the utility model is to increase the accuracy and versatility of use, the ability to obtain data on the pressure of the driver’s hands on various steering wheels.

The device operates as follows.

Electrical signals from pressure sensors (2, Fig. 1), evenly placed on the surface of the steering wheel cover (1, Fig. 1), enter the corresponding analog-to-digital converters (3, Fig. 1), from where they are transmitted after conversion to a digital code in the device for recording received data (4, Fig. 1). As a result, digital data will be obtained, allowing to judge the magnitude of the pressure of the driver’s hands on the steering wheel in its various parts in real time. In the future, this can be used in scientific research in the field of ergonomics and the development of a methodology for the influence of road conditions on the behavior of drivers in order to improve road safety, as well as in the development of technological recommendations for the construction of roads that reduce their estimated costs without compromising performance.
