A rare earth ion doped lanthanum gallate luminous material containing metal particles and preparation method thereof are provided. Data for the data buffer is received. Both the housing and lid are formed of corrosion resistant HASTELLOY\xae C-22\xae alloy. into the vacuum chamber; temporarily laminating the first substrate and the second substrate; venting the vacuum chamber; and bonding the first substrate and the second substrate. The controller drives the EPS motor by implementing a two-phase modulation method and a three-phase modulation method, when at least one of the assist torque, a steering angle acceleration and a function value of a predetermined function is greater and less than a predetermined threshold value indicative of a rapid steering operation, respectively.
