Abstract The joint traction control strategy of dual-clutch transmission （DCT） light off-road vehicle relying on adjusting the engine, inter-axle differential and brakes was presented. The DCT working principle was introduced, and the dynamic model of the shifting process was established. Based on the Matlab/Simulink software platform, dynamic simulation model of DCT and the automated mechanical transmission （AMT） light off-road vehicle were built. The starting and accelerating process were simulated on the low slope separation road and on the split road. The simulation results show that the traction control strategy can improve the vehicle traction on the low coefficient road and the traction performance of DCT vehicle is obviously superior to the AMT vehicle.
