  • Publication number: 20240017718
    Abstract: A vehicle disclosed in the present specification includes a front braking unit, a rear braking unit, a steering unit configured to change a turning angle of at least one of the front wheels and the rear wheels, and a braking controller configured to control operations of the front braking unit and the rear braking unit to brake the vehicle. The braking controller is configured to change a ratio between a front braking force and a rear braking force according to a turning angle when the vehicle is braked. In the vehicle that is making a turn, the wheels are likely to sideslip when the vehicle is braked, and the tendency is changed according to a degree of a turn. Therefore, the sideslip of the wheels is effectively suppressed by changing the ratio between the front braking force and the rear braking force according to the turning angle.

  • Patent number: 10974703
    Abstract: An assembly of a dash panel and a brake master cylinder unit of a vehicle disclosed herein may include: a panel-side support plate arranged between the brake master cylinder unit and the dash panel, the panel-side support plate being parallelly fixed to the dash panel; a unit-side support plate arranged between the dash panel and the panel-side support plate, the unit-side support plate being fixed to the brake master cylinder unit; a first anti-vibration plate interposed between the dash panel and the unit-side support plate; a second anti-vibration plate interposed between the unit-side support plate and the panel-side support plate; and a third anti-vibration plate interposed between the panel-side support plate and the brake master cylinder unit. A rigidity of the second anti-vibration plate in a plate thickness direction may be greater than any of rigidities of the first and the third anti-vibration plates in plate thickness directions.
