Abstract
A control system for a control module of a vehicle includes a first integrated circuit (IC) core of a primary processor that generates a first control signal using a central processing unit (CPU). A second IC core of the primary processor generates a second control signal using a second CPU and generates a remedial control signal based on the first control signal and the second control signal.
Claims15
A control system for a control module of a vehicle, comprising:
- a first integrated circuit (IC) core of a primary processor that generates a first control signal using a central processing unit (CPU);
- and
- a second IC core of said primary processor that generates a second control signal using a second CPU and that generates a remedial control signal based on said first control signal and said second control signal.
A method for operating a control module of a vehicle, comprising:
- generating a first control signal using a first CPU of a first IC core;
- and
- generating a second control signal using a second CPU of a second IC core;
- and
- generating a remedial control signal based on said first control signal and said second control signal.
