Latest Patents
Mitsuhata's latest patents include a vehicle suspension apparatus designed to improve braking control. This invention ensures that if a deceleration exceeds a first set value G1 within a specified time T1 after the brake is applied, a predetermined amount of fluid is supplied to the fluid spring chamber of each front-wheel suspension unit. If the deceleration surpasses a second set value G2 after the initial time T1, fluid is exhausted from the rear-wheel suspension units. This two-stage control mechanism significantly reduces discomfort for passengers during anti-nose-dive braking. Additionally, another patent addresses vibrations in the vehicle body. When vibrations with a specific period are detected, the control unit adjusts the damping force of each suspension unit and manages air supply to the air spring chambers based on vehicle height changes.
