What the present invention utilized the apparent movement motion theory arranges the control tunnel speed of a motor vehicle of apparent movement grating from what driver's speed perception was set about at the tunnel wall, the grating that produces the apparent movement motion is set at the tunnel wall, and the direction of apparent movement motion and the opposite direction of Vehicle Driving Cycle are set, so that driver's perception velocities increases.
Utilize the apparent movement motion theory at the tunnel wall grating (grating refers to make the amplitude of incident light or phase place to be subject to the periodically optical element of spatial modulation) to be set, principal element by control effect apparent movement movement effects, instant apart from (SOA, stimulus onset asynchrony) and spacing (SIS, stimulus separation), the driver is produced be judged as the apparent movement motion perception of " stable in the same way motion ", thereby determine the space layout of the proper form of apparent movement motion.
Difference for the former studies experimental situation, by 3DMAX made under the tunnel environment based on the driver visual angle change video with the reverse apparent movement grating of vehicle forward direction, ratio this index of taking to be judged as " stable in the same way motion " is determined the proper form that apparent movement moves.
Analyze by the result to 6 men, 2 women observation experiments, find that space layout is two bright two dark, four bright four dark, spacing is 2m, 4m, the time apart from be 60ms, 120ms, 180ms, the ratio that is judged as " stable move in the same way " during 240ms all is higher than 95%.Accordingly, made respectively in 16 kinds of situations car with 60km/h with above-mentioned 16 kinds of combinations as proper form, 90km/h, the video that the speed of 120km/h is travelled in the tunnel takes forced choice method design subjectivity to be equal to 282 groups of speed experimental programs.Analyze by the result to 6 men, 2 women observation experiments, find that the grating space layout is two bright two dark, the time apart from being 60ms, the perception velocities of experimenter when spacing is 4m is maximum, and this moment, the standard deviation of 8 experimenter's perception velocities was less, so with the optimised form of this form as the apparent movement grating that is used for speed of a motor vehicle control.
Studies have shown that by experiment: all there are significantly impact (p-value＜0.01) in space layout, SIS, SOA to the apparent movement perception.Can find out from the result of Fig. 5, Fig. 6 and Fig. 7, when the apparent movement grating adopts light and dark, no matter spacing and the time apart from what be, the ratio that the observer is judged as " stable move in the same way " is all very low, all be lower than 50%, be judged as this moment " flashing " or " unsteady motion " more; When the apparent movement grating adopts two bright two dark and four bright four when dark, the ratio that the observer is judged as " stable in the same way motion " significantly improves, the ratio that is judged as " stable in the same way motion " this moment changes along with the variation of SOA and SIS, when SIS is 2m, 4m, when being 60ms, 120ms, 180ms, 240ms, SOA can both obtain stable in the same way motion perception, the ratio that be judged as " stable in the same way motion " this moment all is higher than 95%, and the experimental result of this and Wei Tehaimo is different.The ratio that is judged as " stable in the same way motion " when spatial separation is 6m, 8m reduces gradually.According to this experimental result, choose space layout and be two bright two dark, four bright four dark, SIS is 2m, 4m, SOA is 60ms, 120ms, 180ms, the stimulus of 240ms is as the proper form of apparent movement motion.
All there are appreciable impact (p-value＜0.01) in space layout SIS, SOA to speed perception.Can find out from the result of Fig. 8, Fig. 9, in two dark two bright and four dark four bright situations, apparent movement grating on the tunnel wall all can cause over-evaluating of the speed of a motor vehicle, and shows in the identical situation of identical characteristic: SIS, along with SOA reduce over-evaluate effect and progressively amplify.In the identical situation of SOA, SIS is less, and then to over-evaluate effect larger.Yet and four dark four experimental results of understanding condition lower 8 experimenters bright to two dark two are carried out variance analysis and are obtained respectively, the standard deviation of four bright four 8 experimenter's speed perception when dark is greater than two bright two dark situations, illustrates that four bright four observers' when dark speed perception differs greatly.60(2 among the figure) the expression speed of a motor vehicle is 60km/h, and spacing is 2m, and other in like manner.
Table 1 has been listed the apparent movement movement velocity in different SOA and the SIS situation, and when SIS was identical, the less then apparent movement of SOA movement velocity was larger.Can find out that from testing 2 result the less then perception velocities of SOA is larger, this is in fact that the apparent movement movement velocity is on the impact of perception velocities.
