Abstract
An engine control system includes a torque request control module to determine a first engine torque request. An artificial neural network (ANN) torque request module determines a second engine torque request using an ANN model. A torque security check module that selectively generates a malfunction signal based on the difference between the first engine torque request and the second engine torque request.
Claims12
An engine control system comprising:
- a torque request control module that determines a first engine torque request based on an accelerator pedal position, a vehicle speed, and a cruise torque request;
- a torque control module that controls an engine to generate the first engine torque request;
- an artificial neural network (ANN) torque request module that determines a second engine torque request using an ANN model, the determination of the second engine torque request using the ANN model including:
- determining calculated values as functions of products of the accelerator pedal position, the vehicle speed, and the cruise torque request multiplied by corresponding weights;
- and
- determining the second engine torque request based on the calculated values;
- and
- a torque security check module that selectively generates a malfunction signal based on a difference between the first engine torque request and the second engine torque request,
- wherein the torque control disables a fuel injection system of the engine when the malfunction signal is generated.
