Method for Synchronising Components of a Motor Vehicle Brake System and Electronic Brake Control System
First Claim
1. Method for synchronising components of a motor vehicle brake system comprising the following steps:
- (a) providing an electronic main control device with a main timer associated therewith, and at least one sub-control device, which is subordinate to the main control device, with a sub-control device timer associated therewith, with the main control device communicating with the at least one sub-control device in cycles, and wherein, furthermore, the main control device and the at least one sub-control device in each case increment a cycle counter associated therewith;
b) the main control device sending synchronising data which comprise a value of the cycle counter of the main control device to the at least one sub-control device; and
(c) the at least one sub-control device receives these synchronising data and sets its cycle counter to the received value of the cycle counter of the main control device if the received value of the cycle counter of the main control device differs from the value of the cycle counter of the sub-control device.

Abstract
The invention relates to a method for synchronising components of a motor vehicle brake system with an electronic main control device with a main timer associated therewith, at least one sub-control device, which is subordinate to the main control device, with a timer associated therewith, wherein the main control device communicates with the at least one sub-control device in cycles, wherein, furthermore, the main control device and the at least one sub-control device in each case increment a cycle counter associated therewith. In this connection the main control device sends synchronising data which comprise a value of the cycle counter of the main control device to the at least one sub-control device, and the at least one sub-control device receives these synchronising data and sets its cycle counter to the received value of the cycle counter of the main control device if the received value of the cycle counter of the main control device differs from the value of the cycle counter of the sub-control device.

21. Electronic brake control system for a motor vehicle brake system comprising:
-
an electronic main control device with a main timer and a main cycle counter associated therewith; at least one sub-control device, which is subordinate to the main control device, with a timer and a cycle counter associated therewith, the main control device communicating with the at least one sub-control device in cycles and the main control device and with the at least one sub-control device being synchronised by a method that includes the main control device sending synchronising data which comprise a value of the cycle counter associated with the main control device to the at least one sub-control device and with the at least one sub-control device receiving these synchronising data and setting its cycle counter to the received value of the cycle counter of the main control device if the received value of the cycle counter of the main control device differs from the value of the cycle counter of the sub-control device.
