Braking system for a vehicle, method for operating a braking system of a vehicle, and manufacturing method for a braking system for a vehicle
First Claim
1. A braking system for a vehicle, comprising:
- at least one front axle wheel brake cylinder, in which at least one first brake pressure is built up to exert a front axle braking torque at least one of on a front axle of the vehicle and on at least one wheel of the front axle;
at least one rear axle wheel brake cylinder, in which at least one second brake pressure is built up to exert a rear axle braking torque at least one of on a rear axle of the vehicle and on at least one wheel of the rear axle; and
a control electronics system configured to activate at least one hydraulic component of the braking system in such a way that at least one of the at least one first brake pressure in the at least one front axle wheel brake cylinder and at least one second brake pressure in the at least one rear axle wheel brake cylinder is variable;
wherein a z-critical value specifies, for the braking system, a maximum braking action at which a frictional stress on the front axle of the vehicle and a frictional stress on the rear axle of the vehicle are equal, wherein the braking system is mechanically configured for the z-critical value of at least 0.7 g, and wherein the braking system is controlled by the control electronics during operation using the z-critical value of at most 0.7 g.

Abstract
A braking system for a vehicle includes: a front axle wheel brake cylinder; a rear axle wheel brake cylinder; and a control electronics system for controlling a first brake pressure in the front axle wheel brake cylinder and/or a second brake pressure in the rear axle wheel brake cylinder. A limiting value z-critical is defined for the braking system, which specifies a maximum braking action, at which a traction stress on the front axle of the vehicle and a traction stress on the rear axle of the vehicle are equal. The braking system is mechanically configured for a z-critical of at least 0.7 g, and the braking system is controlled by the control electronics system during operation using a z-critical value of at most 0.7 g.
