Abstract

In order to be able to modify the data in the parameter memory (9) of an electronic control system (1) for motor vehicles in on-line operation, i.e. whilst controlling the motor, the control system (1) is connected to an interactive computer (3) and it is provided that the parameter memory, designed as a read-write memory, is sub-divided into an address area (A), into at least one, generally more, data areas (Di) and into a buffer storage area (Z), the address area (A) located at the starting address of the memory containing the addresses of all data areas (Di) and of the buffer storage area (Z) and the capacity chosen for the buffer storage area being at least equal to the capacity of the largest data area, and that the amended data, determinable in an interactive computer communicating with the control system and intended for a data area (Di) are written into the buffer storage area (Z), whereupon in the address area (A) the address of the data area (Dj) be replaced by the address of the buffer storage area (Z), then the amended data are transferred from the buffer storage area (Z) into the data area (Dj) and finally in the address area (A) the address of the data area (Dj) is reset again to the original address. <IMAGE>
