  • Patent number: 11104319
    Abstract: A braking control device for imparting brake fluid pressure on wheel cylinders in response to operation of a braking operation member to produce braking force includes: first and second fluid pressure units for imparting brake fluid pressure by first and second power sources respectively; and a determining device for determining whether or not operation of the first fluid pressure unit is appropriate. When the determining device determines that operation is appropriate, the first fluid pressure unit imparts brake fluid pressure based on a suitability characteristic, which is the relationship between the brake fluid pressure and the braking operation member operation amount, set in advance. The second fluid pressure unit has proximity characteristics, generally matching the suitability characteristic, and notification characteristics, different from the suitability characteristic.
