Abstract: An Engine Control Unit (ECU) for adapting to irregularities in a trigger wheel includes a memory element that stores a table with data of dimensions of the trigger wheel. The ECU is configured to (i) use a position sensor to detect a tooth and a corresponding tooth number, and (ii) set a time range for detection of a subsequent tooth with reference to the data in the memory element. The ECU is further configured to (iii) prevent errors due to irregularities in the trigger wheel in order to reinforce the ECU or an Engine Position Management System (EPMS) by adapting to a profile of each tooth of the trigger wheel, and in order to avoid an error in a plausibility check of the position sensor due to irregularities in the trigger wheel.

Abstract: The system is provided to calibrate the ECU of the vehicle. The system comprises a remote computer, a central server, a local computer and setup comprising at least a dynamo meter, and at least one actuator. The dynamo meter and the actuator are interfaced and operated with the local computer. The central server is connected to the local computer by a second networking means, and a remote computer is connected to the central server by a first networking means. The remote computer, uploads instructions to the central server, executes the instructions through the local computer to operate the dynamo meter and the actuator, and calibrates the ECU of the vehicle. The instructions are downloaded to the local computer by the second networking means.
