Latest Patents
One of his latest patents is a steering ratio control system for vehicles. This system includes a variable steering ratio mechanism that adjusts the steering ratio of the left and right steered road wheels based on the steering-wheel rotation angle. It features a braking/driving force control unit that individually manages the braking and driving forces of the wheels. The steering ratio control unit determines a reference steering ratio based on the vehicle's driving state and calculates a correction value to cancel torque steer caused by differences in braking and driving forces. The final steering ratio is then determined to ensure responsive handling.
Another significant patent is a driving force controlling apparatus and method for four-wheel drive vehicles. This invention outputs a command to a front-and-rear wheel driving force distribution control system. It reduces the clutch engagement force of a frictional clutch when specific conditions are met, ensuring optimal performance and stability of the vehicle.
