Embodiment Construction
[0044] The present invention will be further described below with reference to the drawings and embodiments. Such as Figure 4 As shown, the power assist characteristic curve diagram of the electric power steering system of the heavy transportation vehicle of the present invention.
[0045] First, in order to protect the motor from frequent starting of the motor, the initial assist steering wheel torque T is set in different speed intervals. 0 =±1Nm, T 1 =±1.5Nm, T 2 =±2Nm. The initial assist steering wheel torque increases gradually with the increase of speed, the purpose is to enhance the sense of stability pursued during high-speed steering. At the same time 0≤T d i (V i ) (i=0, 1, 2) The EPS does not work in the interval, which is also conducive to improving the energy-saving efficiency of the EPS system.
[0046] Secondly, determine the maximum assist torque of the electric motor under various working conditions. For vehicles equipped with the same type of EPS, the maximum boo...
