The left and right rear drive wheels of a vehicle are controlled independently, and the traveling direction of the vehicle is changed by providing a rotational speed difference between each of the left and right rear drive wheel. A vehicle operator merely designates the turning direction by moving an operation stick, e.g., to the left or right, which will in turn enable an automatic turn at an optimum curvature to be performed which frees the vehicle operator from complicated steering operations. A highly precise and responsive turn is achieved when the left and right independent control is implemented with a PLL control circuit.

Disclosed is an explosive reactive armor with a momentum transfer mechanism by developing a new protection mechanism in which a momentum transfer mechanism by detonation of a reactive material is integrated with a thickness increase mechanism. In this explosive reactive armor with the momentum transfer mechanism, a flying element always travels with a vertical angle or a slant angle with respect to an ongoing direction of the threat such that a momentum of the flying element is transferred to the threat effectively. As a result of this, shear force is induced over an entire length of the threat and thus the threat can be destroyed. Therefore, a protection effect can always be achieved regardless of an impact angle of the threat. Also, a protection capability can be achieved even in case of a vertical impact which is the most vulnerable case for the existing explosive reactive armor.
