【 摘 要 】

Torque vectoring has huge impact on vehicles steering characteristics. Most of the literature refer to the vehicles with a wheel track typical for passenger cars. This paper examines whether for the narrow vehicle (with a very small wheel track) torque vectoring is possible to be used in an active safety systems, securing it from roll over (roll mitigation). This paper deals with the description of current vehicle technology related to traction control through the employment of effective torque vectoring strategies for electric vehicles. The work contains a description of simulation models. The bicycle model of a vehicle is arranged and suitable adapted for the test subject. The paper contains a set of simulation compared with road tests of the narrow vehicle. The usefulness of a simple linear single track vehicle model to describe the movement was tested. The vehicle understeer characteristic as a function of a power distribution is presented.
