<p>PROBLEM TO BE SOLVED: To provide a driving force transmission control device capable of preventing an unnecessary increase of torque transmission. SOLUTION: When a transmission torque command value T3 is smaller than a threshold value Tt (S64: No), a duty ratio is operated corresponding to the transmission torque command value T3. When a transmission torque corrective command value T4 is less than a transmission torque upper limit value Tmax (S70: No), a duty ratio is operated corresponding to the transmission torque corrective command value T4. When the transmission torque corrective command value T4 exceeds the transmission torque upper limit value Tmax (S70: Yes), the transmission torque corrective command value T4 is set to be the transmission torque upper limit value Tmax (S72), and the duty ratio is operated corresponding to the transmission torque upper limit value Tmax. A voltage based on the duty ratio decided in a process S8 is applied to an electromagnetic coil of an electromagnet driving a clutch mechanism. The applied voltage, an energization current, and magnetic force at the electromagnetic coil are duty-controlled.</p> |
