PROBLEM TO BE SOLVED: To provide a drive control device appropriately carrying out a changeover from main and subordinate drive to main drive in a structure of carrying out traction control of each of a main drive wheel and a driven wheel independently.SOLUTION: A drive control device 1 is used for a vehicle V capable of performing a changeover between two-wheel driving (main drive) for only driving main driving wheels FR, FL, and four-wheel driving (main and subordinate drive) for also driving driven wheels RR, RL. The drive control device includes: a traction control means 10 for carrying out traction control of each of the main driving wheels FR, FL and the driven wheels RR, RL independently; a drive changeover means 20 for performing a changeover between the two-wheel driving and four-wheel driving; and a four-wheel driving release allowing means 30 (a main and subordinate drive release allowing means) for allowing a changeover from the four-wheel driving to the two-wheel driving. The four-wheel driving release allowing means 30 does not allow the changeover from the four-wheel driving to the two-wheel driving when the traction control is carried out over at least one of the main driving wheels FR, FL and the driven wheels RR, RL. |
