Process and device for an open-loop control and a closed-loop control of a brake system of a vehicle

A process for at least one of an open-loop control and a closed-loop control of a brake system of a vehicle having a computer system with at least two microcomputers, comprising the steps of:

• determining at least two actuation parameters corresponding to a brake pedal actuation by a driver;
• performing at least one of the following steps:
• (a) determining a driver braking command in a computer system as a function of the at least two actuation parameters, the driver braking command being formed as a function of predefined relationships between the driver braking command and the at least two actuation parameters, the driver braking command being converted into setpoints for controlling wheel brakes;
• and
• (b) identifying an error as a function of the at least two actuation parameters;
• controlling the wheel brakes in at least one of an open loop and a closed loop as a function of the setpoints;
• wherein at least one of the determination of the driver braking command, the determination of the setpoints, and the identification of the error is performed in each of the at least two microcomputers independently of others of the at least two microcomputers, the at least one of the determination of the driver braking command, the determination of the setpoints, and the identification of the error further being performed in each of two independent processing channels in one of the at least two microcomputers.
