Method of initializing a system for open/closed-loop control of the operational sequences of a motor vehicle and a system for carrying out the method
First Claim
1. A method of initializing a system for an open/closed-loop control of an operating sequence of a motor vehicle that includes a controller connected to a plurality of sensors via a data bus, the method comprising the steps of:
- subdividing the sensors into sensors of the same type;
causing the controller to transmit a transmission request to the sensors of the same type;
causing the sensors of the same type to transmit a response to the controller that is staggered in time by an operation of a staggering arrangement; and
during the transmission of the response, causing the controller to overwrite a data field of each response of the sensors with a sensor-specific identifier and a corresponding transmission priority.

Abstract
A method of initializing a system for open/closed-loop control of the operating sequences of a motor vehicle is described. The system has a controller which is connected to a number of sensors via a data bus. The sensors have suitable means which allow a response to be transmitted staggered in time. In order to initialize the system, the controller first transmits a transmission request to sensors of the same type. The sensors of the same type transmit responses staggered in time back to the controller. During the transmission of the responses, a data field of each response is overwritten by the controller with a sensor-specific identifier and a corresponding transmission priority.
