ABSTRACT:
FIELD OF THE INVENTION
A decentralized electrical braking system (e.g., brake by wire) for a motor vehicle which, due to its decentralized configuration, is capable of meeting high technical demands with respect to safety and availability.
BACKGROUND INFORMATION
A conventional braking system is described in German Patent Application No. 196 34 567. This conventional braking system has a decentralized structure in which a pedal unit for forming the command variables, which are a function of the driver's input, optionally a processing unit for the consideration of additional functions, as well as wheel-pair units for the open-loop or closed-loop control of the final controlling elements of the wheel brakes are connected via one or a plurality of communication systems. Furthermore, the braking system is supplied with energy from at least two vehicle electrical systems. In this manner, satisfactory reliability and availability of the braking system is ensured. A “pedal unit” forms setpoint values for the brake control in response to a service braking. An inclusion of a parking brake function is not described.
One of the objects of the present invention is to specify measures for the incorporation of a parking brake function into a decentralized braking system.
SUMMARY OF THE INVENTION
An incorporation of a parking-brake function into a decentralized braking system is possible using the electrical braking system according to the present invention.
In so doing, it is advantageous that the necessary operational reliability and availability are also ensured with respect to the parking brake. For example, the functional reliability of the unit evaluating the driver's braking inputs is verified without great expenditure for hardware.
Furthermore, the parking-brake input and the service-brake input of the driver are advantageously coordinated with one another.
