THE VOLVO ELECTRONIC TRACTION CONTROL (ETC) SYSTEM

Lars Lind

Open publisher page 2 citations

Abstract

When driving on low–friction road surfaces or on roads with variable friction conditions, it is easy to lose control of the car, especially when stepping too hard on the accelerator pedal. The problem is increasing with the use of more powerful high–performance, turbocharged engines. Especially when overtaking, it is easy to lose driving wheel lateral stability by a too high wheel spin rate, causing dangerous skidding. The Volvo ETC system has been developed to avoid such situations. lt is designed to optimize traction and lateral stability by controlling engine torque in response to the actual road conditions. This paper describes the theoretical background, the component and the functions of the Volvo ETC system.
