“…A torque vectoring differential is a system based on a conventional differential gear, and it is usually connected with one or more of different ratio speeds and clutches (or brakes) that can transfer input torque efficiently and direct the power flow separately into wheels while a vehicle is in acceleration or cornering. Torque vectoring differential is now a popular system and several different types of torque vectoring differential are invented by automobile companies such as Mitsubishi [6], Audi [7], and Honda [8]. However, in most current torque vectoring differentials, issues of structural complexity, space requirement, development cost, etc.…”

Abstract. In this paper, a new concept torque vectoring differential (TVD) system is presented. It is shown that the structure and the mechanism of the system, the operating methods, and the parameters design by a simulation program, i.e. SimulationX. First of all, the structure of the new TVD system is introduced, as well as the relevant mechanic equations. Second, we attempt to verify the feasibility and accuracy of SimulationX through establishing a simple mechanical model by MATLAB, so that the further modeling and simulation results of the new TVD system will be credible. Then, the simulation results at the setting conditions are presented. Finally, the sensitivity of the design parameters is analyzed, including adjusting the braking torque and the dimensions of the gear sets in the differential. According to these results, the characteristics of the new TVD system can be derived in order to develop the whole system with vehicle dynamic model in the next stage.
