Abstract

The present invention relates to an electronic control system for a motor vehicle, including a control device, an actuator, and at least one sensor. The control system according to the invention is characterized in that it has a sensor board for reading the data detected by the sensor, wherein the sensor board has a memory for storing actuator-specific data and an interface between the sensor board and the control device for transferring the data stored in the sensor board to the control device. The present invention also relates to a method for operating this type of control system.

Claims

1. A method for operating an electronic control system having:

a controller, an actuator and at least one sensor

a sensor board for reading data which is detected by the sensor, the sensor board has a memory for storing actuator-specific data and

an interface between the sensor board and the controller for transmitting the data which is stored in the sensor board to the controller, wherein said method comprising comprises;

starting the controller;

transmitting the actuator-specific data which is stored in the sensor board to the controller;

comparing the actuator-specific data which is transmitted from the sensor board with actuator-specific data which is stored in the controller;

switching the controller to a normal operating mode when the actuator-specific data which is transmitted from the sensor board corresponds to the actuator-specific data which is stored in the controller;

starting a training process when the actuator-specific data which is transmitted from the sensor board does not correspond to the actuator-specific data which is stored in the controller, said training method comprising the following sub-steps;

storing the actuator-specific data which is transmitted from the sensor board in the controller;

configuring the controller in accordance with the actuator-specific data which is transmitted from the sensor board; and

switching to the normal operating mode of the controller.

2. The method as claimed in claim 1, wherein sensor data is read from the sensor board and transmitted to the controller in the normal operating mode of the controller.

3. The method as claimed in claim 1, further comprising performing data transmission between the sensor board and the controller by a field bus.

4. An electronic control system for a motor vehicle, comprising:

—

a controller, an actuator and at least one sensor;

—

a sensor board for reading data which is detected by the sensor, the sensor board has a memory for storing actuator-specific data; and

—

an interface between the sensor board and the controller for transmitting the data which is stored in the sensor board to the controller, wherein the controller compares the actuator-specific data which is transmitted from the sensor board with actuator-specific data which is stored in the controller and starts a training process when the actuator-specific data which is transmitted from the sensor board does not correspond to the actuator-specific data which is stored in the controller, and wherein the training process includes configuring the controller in accordance with the actuator-specific data which is transmitted from the sensor board.

5. The electronic control system as claimed in claim 4, wherein the sensor board is physically arranged between the controller and the actuator, and the sensor board is connected to the actuator.

6. The electronic control system as claimed in claim 4, wherein the at least one sensor is arranged on the sensor board.
