- the data is sent to the processing unit 210 (step S10).
- the drive control processing unit 208 calculates the traveling speed, traveling position, etc. of the virtual train based on the track data and vehicle data read from the memory, and determines the traveling speed and traveling position by the conductor control processing unit.
- the travel position is sent to 205 (step S11), the travel position is sent to the trajectory control processing unit 209, and the acceleration and travel position are sent to the vehicle model calculation processing unit 210 and the sound generation processing unit 211 (step 14).
- trajectory control processing unit 209 calculates a trajectory error and sends it to the vehicle model calculation processing unit 210 (step S 13).
- the vehicle model calculation processing unit 210 calculates the displacement of the spring and sends it to the sound generation processing unit 211.
- the drive control processing unit 208 supplies the travel position and travel speed to the image generation processing unit 401 (Step S 16).
- the vehicle model calculation processing unit 210 calculates the displacement (vehicle body displacement) due to the shaking of the vehicle, and sends the calculated vehicle body displacement to the image generation processing unit 401 of the visibility display PC 4 (step S17).
- the view display PC 4 reads the landscape data 400 stored in the memory unit and sends it to the image generation processing unit 401 (step S18).
- the image generation processing unit 401 receives from the drive control processing unit 208. Based on the supplied travel position and travel speed and the vehicle model calculation processing unit 210 force, the vehicle body displacement is generated to generate an image representing 'swaying landscape', and the generated frame based on the command of the vehicle PC20 Each image is supplied to the projector 3 (step S19).
- the projector 3 supplies the generated image to the screen 6 (step S21).
- the sound generation processing unit 211 outputs sound reproduced based on the supplied alarm information, broadcast information, buzzer information, and the like from the speaker 1 (step S20).
- the railway driving simulator is adapted to the vehicle operation according to the operation of the vehicle. Controls the driving state, and displays the view from the virtually traveling vehicle as a three-dimensional “swinging landscape” based on the traveling position and traveling speed, and the vehicle body displacement due to the vehicle shaking. A running sound, a traffic light warning sound, and a vehicle roaring sound are output according to the displayed image, so that a sense of reality and tension as if driving an actual train can be obtained.
- a command is issued from the command PC, predetermined data stored in the memory unit is selected, and the simulator environment can be flexibly set and changed.
