The invention discloses a novel full-decoupling electronic hydraulic brake system and a vehicle, and relates to the technical field of vehicle braking, the novel full-decoupling electronic hydraulic brake system comprises a brake pedal, a push rod, a brake master cylinder, a brake fluid storage tank, a pedal feeling simulator, an electronic control unit, a motor, a secondary master cylinder and a wheel cylinder, the secondary main cylinder is connected with the brake fluid storage tank; based on the displacement effect of a brake pedal, an electronic control unit controls a motor to push brake fluid in a secondary main cylinder to a wheel cylinder so as to achieve four-wheel brake boosting or single-wheel pressurization to achieve stable control over a vehicle body. And when the electronic control unit fails, the brake fluid in the brake master cylinder is directly pushed to each wheel cylinder under the displacement action of the brake pedal, so that failure protection is realized through mechanical braking. The system is smaller in size, lighter in weight and lower in production cost; and when the electronic brake fails, the effects of increasing the pressure more quickly and ensuring the driving safety of the vehicle are achieved.
