  • Control unit with an interface for motor vehicles that is capable of being programmed with new control data and operating programs
    Patent number: 5247446
    Abstract: A digital control unit, in particular an ignition and/or injection control unit for motor vehicles, is provided. The control unit has a microcomputer (10) and a permanently connected main storage (12) containing control data and operating programs. This main storage unit (12) is designed as a read/write memory (RAM, EEPROM or the like). A control program that runs when the control unit is switched on is provided in an auxiliary storage (13) designed as a permanent storage (ROM, EPROM or the like). Based on a load instruction, the control program controls the loading of the main storage (12) from an external storage medium via an interface (21). The control program also automatically transfers the operating program access of the microcomputer (10) to the main storage (12). In this manner, software modifications can easily be subsequently implemented in the control unit when, for example, improvements or variations in program data or characteristic data are available and desired.
