Method for adjusting the pressure pressure of a vehicle brake and related vehicle
By dynamically adjusting the applied pressure in the vehicle brake, the unnecessary friction torque and braking force are reduced according to the comparison of the braking effect and the boundary braking effect, the wear and kinetic energy loss caused by the applied pressure in the prior art is solved, and more efficient braking response and battery life are achieved.

AI Technical Summary
Technical Problem
The prior art, when pressure is applied in a vehicle brake, results in undesired friction torque and braking force, increasing wear and losing kinetic energy.
Method used
By obtaining the braking effect during the initial applied pressure on the vehicle brake, and comparing it with the boundary braking effect, if the boundary braking effect is exceeded, the applied pressure is reduced, and iterative adjustment is made until the braking effect is smaller than the boundary braking effect.
Benefits of technology
It effectively reduces unnecessary high braking torque when the brake is not used, reduces wear of the wheel brakes, increases the regeneration of kinetic energy, and increases the range of the electric-driven vehicle.

Abstract
The invention relates to a method (102, 202) for adjusting a pressure application (p) of a vehicle brake (2), in particular a commercial vehicle disc brake (4), of a motor vehicle (1) during driving of the motor vehicle (1). According to the invention, the method (102, 202) comprises the following steps: applying (104, 204) an initial pressure application (pa) to the vehicle brake (2), ascertaining (106, 206) a braking effect (Fb) of the vehicle brake (2) during the application of the initial pressure application (pa) to the vehicle brake (2), comparing (108, 208) the ascertained braking effect (Fb) with a boundary braking effect (Fg), and if the ascertained braking effect (Fb) exceeds the boundary braking effect (Fg), determining (106, 206) the braking effect (Fb) of the vehicle brake (2). If so, the initial pressure (pa) is reduced (110, 210) to a reduced pressure (pr).
