UN ECE R140 tests cover a series of tests carried out in accordance with the relevant regulation for the evaluation of vehicles in the categories specified in the regulation in terms of Electronic Stability Control (ESC) equipment.
ECE regulations define cross-border technical regulations for establishing approval or uniform approval procedures for motor vehicles and motor vehicle parts. Automated commercial vehicles are already fully eligible for approval only through appropriate individual measures in the country in which they will be used. What is missing is a set of rules at the international ECE level.
Regulation No. 140 of the United Nations Economic Commission for Europe (UN/ECE) — covers the uniform provisions regarding the approval of passenger cars and the tests applied accordingly with regard to Electronic Stability Control (ESC) Systems.
This Regulation is valid for the approval of vehicles of category M1 and N1 with regard to electronic stability control systems and does not cover the following;
Electronic Stability Control (ESC) helps prevent loss of control in corners and emergency steering maneuvers by stabilizing your vehicle when it starts to deviate from your desired path. It works automatically to help the driver maintain control of the vehicle during hard steering manoeuvres.
Electronic stability control (ESC) activates automatically when you start your vehicle or to help prevent oversteer and understeer. ESC works by braking individual wheels and reducing engine speed, helping you maintain control.
Within the scope of the regulation, many mechanical, dynamic and environmental tests are carried out as well as measurements for the approval of the relevant equipment. For tests to be considered successful, test results must meet regulatory requirements.
