Control device for a braking system of a vehicle, braking system, and method for operating a braking system for a vehicle

摘要

A control device for a braking system of a vehicle, with the aid of which at least one provided setpoint variable regarding a setpoint brake pressure to be set in a first brake circuit and at least one provided actual variable regarding an actual brake pressure that is present in the first brake circuit, and/or an elasticity variable regarding an elasticity of a second brake circuit of the braking system are receivable, and a default variable regarding a setpoint additional volume of a brake fluid of the second brake circuit which is in a main cylinder braking mode is establishable, by taking into account a first deviation variable of the at least one actual variable from the at least one setpoint variable, and/or a second deviation variable of the elasticity variable from a predefined setpoint elasticity variable, so that a control signal corresponding to the established default variable is outputtable to at least one volume conveying device. Moreover, also described is a method for operating a braking system for a vehicle.

1. A control device for a braking system of a vehicle, comprising:
at least one of:
a first receiving device, wherein, with the aid of the first receiving device, at least one provided setpoint variable regarding a setpoint brake pressure to be set at least one of in a first brake circuit of the braking system and in at least one first wheel brake cylinder of the first brake circuit is receivable;a second receiving device, wherein, with the aid of the second receiving device, at least one provided actual variable is receivable regarding at least one of: an actual brake pressure that is present at least one in the first brake circuit and in the at least one first wheel brake cylinder, and an actual braking torque exerted on at least one wheel by the at least one first wheel brake cylinder; anda third receiving device, wherein, with the aid of the third receiving device, an elasticity variable regarding an elasticity of a second brake circuit of the braking system is receivable; an evaluation device, with the aid of which a default variable regarding a setpoint additional volume of a brake fluid of the second brake circuit which is in a main brake cylinder braking mode is establishable, a pressure in the second brake circuit which is in the main brake cylinder braking mode being controllable with the aid of a main brake cylinder of the braking system, taking into account at least one of a first deviation variable of the at least one actual variable from the at least one setpoint variable and a second deviation variable of the elasticity variable from a predefined setpoint elasticity variable; and a control device, with the aid of which a control signal corresponding to the established default variable is outputtable to at least one volume conveying device of the braking system in such a way that with the aid of the at least one volume conveying device an actual additional volume of the brake fluid corresponding to the setpoint additional volume is introducible from a storage volume of the braking system into the second brake circuit which is in the main brake cylinder braking mode.
