## Abstract

A method for verifying actuator control data includes a first operation of transmitting, by a host computer, a plant model to a simulator for verifying actuator control data, a second operation of transmitting, to an engine controller connected to an actuator, an engine simulation information signal of the plant model that is received from the simulator, a third operation of driving, through the engine controller, the actuator according to the engine simulation information signal, receiving, by the engine controller, a feedback signal transmitted from the actuator, transmitting the feedback signal to the host computer, and measuring control data, and a fourth operation of comparing the control data with target control data preset in the host computer and verifying whether the control data is abnormal.

## Claims

### Claim 1

A method for verifying actuator control data, comprising:
transmitting, by a host computer, a plant model to a simulator for verifying actuator control data;
transmitting, to an engine controller connected to an actuator, an engine simulation information signal of the plant model that is received from the simulator;
driving, through the engine controller, the actuator according to the engine simulation information signal, receiving, by the engine controller, a feedback signal transmitted from the actuator at a time of driving the actuator, transmitting the feedback signal to the host computer, and measuring, through the host computer, the actuator control data from the feedback signal; and
comparing the actuator control data with target control data preset in the host computer and verifying whether the actuator control data is abnormal,
wherein the verifying of whether the actuator control data is abnormal comprises:
comparing a preset target actuator position and an actual actuator position, when the target speed stored in the host computer and the actual vehicle speed are compared and the value resulting from the comparison is determined to be within the preset range;
comparing a preset target actuator position response time and an actual target actuator position response time, when the target actuator position stored in the host computer and the actual actuator position are compared and the value resulting from the comparison is determined to be within the preset range;
checking whether the plant model and the simulator are abnormal, when a difference between the target actuator position response time stored in the host computer and the actual target actuator position response time are determined not to be within a preset range.

### Claim 2 (depends on 1)

The method of claim 1, wherein the measuring of the actuator control data comprises:
transmitting the feedback signal transmitted from the actuator to the plant model and the simulator together with the engine controller.

### Claim 3 (depends on 1)

The method of claim 1, wherein the verifying of whether the actuator control data is abnormal comprises:
checking whether the plant model and the simulator are abnormal, when a target speed stored in the host computer and an actual vehicle speed are compared and a value resulting from the comparison is determined not to be within a preset range.

### Claim 4 (depends on 1)

The method of claim 1, wherein the verifying of whether the actuator control data is abnormal comprises:
checking whether the plant model and the simulator are abnormal, when the target actuator position stored in the host computer and the actual actuator position are compared and a value resulting from the comparison is determined not to be within the preset range.

### Claim 5 (depends on 1)

The method of claim 1, wherein the transmitting of the plant model to the simulator comprises:
transmitting engine simulation information, vehicle simulation information and environmental condition information included in the plant model to the simulator.
