  • Patent number: 11738728
    Abstract: A step determination device includes an operation amount sensor that detects an operation amount of a braking operation member, and a controller that determines a step by using the wheel speed and the operation amount. In the step determination device, the controller calculates an actual variable amount by using the wheel speed, calculates an estimated variable amount corresponding to the actual variable amount by using the operation amount, and executes the determination of the step by using the actual variable amount and the estimated variable amount. For example, the controller determines the presence of the step when the deviation between the actual variable amount and the estimated variable amount is not less than a predetermined value, and determines the absence of the step when the deviation is less than the predetermined value.

  • Patent number: 11708109
    Abstract: A shock damper is disposed between a vehicle body side and a wheel side. A suspension control device calculates a damping force of the shock damper on the basis of vehicle height information and controls the damping force. A steering system includes an electric motor and a steering control device that controls the electric motor, and assists steering effort of the driver through the electric motor. The suspension control device calculates the vibration generated in a steering on the basis of a detected value of a vehicle height sensor and creates a signal for generating steering torque that reduces the generated vibration. The suspension control device outputs the created signal to the steering control device. Steering torque for cancelling steering vibration is accordingly outputted from the electric motor of the steering system.
