Abstract
A control system for a load (10), the system comprising a first microprocessor (16) having an output to drive one side of a load (10), a second microprocessor (18) having an output to drive the other side of the load (10), the system being arranged so that when either microprocessor detects a fault in the control of the load (10) the load (10) is switched off.
Claims20
A control system for a load, the system comprising a first microprocessor having an output to drive one side of a load, a second microprocessor having an output to drive the other side of the load and being arranged to monitor the operation of the load, the system being arranged so that when either microprocessor detects a fault in the control of the load the load is switched off.
The method of controlling a load comprising the steps of:
- driving one side of the load with a first microprocessor,
- driving the other side of the load with a second microprocessor,
- monitoring the operation of the load, and
- switching the load off when either microprocessor detects a fault in the control of the load.
A method according to clam 11 wherein the control method is applied to a vehicular control system.
