  • Patent number: 10737670
    Abstract: A brake fluid pressure control device for a vehicle that can perform fluid pressure control on the brake fluid pressure applied to wheel brakes. It is determined whether the pressure increasing time in the current pressure increasing control exceeds determination time which is set on the basis of the pressure increasing time in past pressure increasing control. If the pressure increasing time in the current pressure increasing control exceeds the determination time, it is determined that the road surface on which the vehicle is travelling has changed from the road surface with a low coefficient of friction to the road surface with a high coefficient of friction.

  • Patent number: 10731718
    Abstract: For a vehicle disc brake, a piston-side first friction pad is provided with at least one protrusion on a piston-contacting section that excludes the central axis line of the piston and the piston is provided with an engagement hole capable of engaging with the protrusion. Symmetric with the piston-side first friction pad with a brake disc therebetween, a reaction pawl-side second friction pad is provided with a protrusion. As a result, it is possible to provide a vehicle disc brake in which the first friction pad and the second friction pad are both made to have a protrusion, reducing the possibility of incorrect assembly, and the friction pads themselves are made to be used in common, facilitating product management.

  • Patent number: 10723333
    Abstract: A brake fluid pressure control device for a includes a wheel speed acquisition device that acquires a wheel speed, a slippage amount calculation device that calculates a wheel slippage amount, and a bad road determination device that determines whether a road surface of travel is a bad road. The bad road determination device determines whether the road surface of travel is a bad road using a bad road determination threshold value, and a value that relates to wheel behavior that is calculated based at least upon the wheel speed. The bad road determination threshold value is modified according to the wheel slippage amount. The present invention can appropriately set a bad road determination threshold value that is in accordance with a slippage amount, which corresponds to braking power, and can improve bad road determination precision without depending on variation in change of wheel speed.
