Brake Pressure Control for Covert Vehicle Theft Prevention

The patent introduces torque adjustment as an intermediary mechanism between the accelerator operation and the actual driving torque. By adding an offset to the required driving torque, the system creates a hidden layer of control that prevents the thief from directly observing or disabling the brake locking mechanism, as the abnormal torque requirements mask the actual brake intervention

The patent changes the parameter of driving torque by adding an offset that increases the required driving torque based on accelerator operation amount. This parameter change creates a subtle, hard-to-detect modification in vehicle behavior that prevents theft without alerting the perpetrator, while the hydraulic circuit simultaneously pressurizes brake fluid to compensate for the increased torque requirement

The patent applies partial braking action rather than full wheel locking. The brake fluid pressure is adjusted to compensate for the increased driving torque requirement, creating a subtle resistance that prevents theft without completely locking the wheels. This partial action maintains vehicle controllability while still achieving the theft prevention objective

The patent dynamically adjusts brake fluid pressure parameters to match the offset torque requirements. By changing the brake pressure parameter in response to accelerator operation, the system maintains smooth vehicle operation and controllability while preventing theft through cumulative torque resistance
