CVT Clutch Torque Control for Belt Slipping Prevention

The control apparatus performs preliminary action by detecting tire slip states and proactively reducing clutch torque capacity before sudden braking occurs. When a tire slip state is detected, the control unit reduces the clutch torque capacity in advance, so that when sudden braking occurs later, the belt is already protected from slipping. This preliminary preparation resolves the contradiction by ensuring the protective torque reduction is already in place before the critical moment arrives.

The control apparatus dynamically adjusts the clutch torque capacity based on real-time detection of tire slip states and braking conditions. Rather than using a fixed torque capacity, the system continuously monitors wheel rotation speeds, detects tire slip, and adaptively modifies the clutch torque capacity. This dynamic adjustment ensures optimal torque capacity at each moment, preventing belt slipping while responding quickly to changing conditions.

The control apparatus dynamically adjusts the clutch torque capacity based on real-time detection of tire slip states and braking conditions. During normal operation without tire slip, the clutch torque capacity is maintained at normal levels for efficient power transmission. When a tire slip state is detected, the torque capacity is temporarily reduced. This dynamic adjustment resolves the contradiction by ensuring the clutch torque capacity is only reduced when necessary for belt protection.

The control apparatus applies different torque capacity settings to different operational conditions. Instead of using a uniformly reduced torque capacity that would cause excessive clutch slip during normal operation, the system applies torque capacity reduction only locally to the specific condition of tire slip state detection. This selective application ensures normal power transmission is maintained while protecting the belt when needed.
