An embodiment of the present invention relates to a traverse direction control method, apparatus, and moving object for autonomous driving. More particularly, the traverse direction control apparatus for autonomous driving includes an information collection part for collecting data from one or more cameras mounted on an autonomous moving object; a target point information calculation module for calculating target point information on the basis of information collected from a camera module; and a traverse direction control parameter calculation module configured to obtain, based on the target point information, a traverse direction distance from the moving object at time t to a target point, an angle between a head of the moving object and the target point, and a present yaw rate of the moving object, and calculate a traverse direction control parameter of time t+1 based on a pre-stored kinematic model.

The present invention relates to an improved process for preparing simvastatin and more particularly, the improved process for preparing simvastatin expressed by formula 1 with high yield and high purity by performing the following sequential processes comprising: (i) hydrolysis of lovastatin as starting material with potassium t-butoxide in an organic solvent and small amount of water under a mild reaction condition, followed by lactonization of the obtained solid intermediate with preventing from formation of by-products; (ii) protection of an alcohol group with t-butyldimethylsilyl group which can be easily removed with concentrated hydrochloric acid without the formation of by-products; (iii) acylation of the obtained protected intermediate with acyloxytriphenyl phosphonium salt as an acylating agent under a mild reaction condition; and (iv) removal of the silyl protective group with a concentrated hydrochloric acid. The present invention is to provide the improved process of preparing simvastatin expressed by formula 1 environmentally sound, economically efficient, and industrially useful.
