Dual processor supervisory control system for a vehicle
First Claim
1. A vehicle control module for controlling an actuator unit in response to an input, the vehicle control module comprising:
- a first processor configured to;
generate a first value based on said input;
transmit said first value to the actuator unit; and
receive a second value from the actuator unit based on a data received by the actuator unit from said first processor;
a first communication link coupled to said first processor; and
a second processor coupled to said first processor via said first communication link, said first communication link configured to transfer said input and said second value to said second processor, said second processor configured to;
determine a third value based on said input; and
verify said first value based on a comparison of said second value with said third value.

Abstract
A vehicle control module for controlling an actuator unit in response to an input having a first processor, a first communication link coupled to the first processor, and a second processor coupled to the first processor via the first communication link. The first processor is configured to generate a first value based on the input, transmit the first value to the actuator unit, and receive a second value from the actuator unit based on a data received by the actuator unit from the first processor. The first communication link is configured to transfer the input and the second value to the second processor. The second processor is configured to determine a third value based on the input, and verify the first value based on a comparison of the second value with the third value.
