Abstract
Proposed is an electronic hydraulic brake apparatus including a primary brake unit providing a brake fluid to a plurality of wheel cylinder units, a storage unit connected to the primary brake unit, the brake fluid being stored in the storage unit, and an auxiliary brake unit selectively connected to the primary brake unit and, in a case where an operating error of the primary brake unit occurs, providing the brake fluid stored in the auxiliary brake unit itself to the wheel cylinder unit.
Claims20
An electronic hydraulic brake apparatus comprising:
- a primary brake unit configured to provide a brake fluid to a wheel cylinder unit;
- a storage unit connected to the primary brake unit and configured to store the brake fluid;
- and
- an auxiliary brake unit connected to a hydraulic line of the primary brake unit, and configured to selectively disconnect from the primary brake unit and provide additional brake fluid which is stored separately within the auxiliary brake unit without being hydraulically connected to the storage unit, to the wheel cylinder unit in a case where an operating error of the primary brake unit occurs.
