In an interactive driving simulation apparatus for a two-wheeled vehicle, a real-time test drive performance by a student operator around a simulated driving route sequence is recorded. The recorded performance is later replayed for the benefit of the student, to provide real-world simulation, education, and performance evaluation. During the simulated driving, pre-recorded performance evaluation comments are selected and stored, corresponding to the student's specific performance at a traffic driving situation on the driving route sequence. Then, upon displaying of a replay screen image of the simulated driving on a display unit, when a particular traffic driving situation is arrived at, a simulated operating environment of the traffic driving situation and the selected performance evaluation comments are automatically superimposed and displayed together as a replay screen 154.

The invention relates to an automatic driving simulation system which includes a driving environment simulation module, a vehicle power simulation module, and a control module. The vehicle power simulation module is used for providing a simulated vehicle. The driving environment simulation module is used for providing a simulated driving environment for the simulated vehicle and providing a simulated sensor for the simulated vehicle. The simulated sensor is used for detecting a sensing signal generated by the simulated vehicle in the driving process of the simulated vehicle in the simulated driving environment. The control module is used for generating a control instruction according to the sensing signal. The vehicle power simulation module is used for executing the control instruction tocontrol the driving of the simulated vehicle in the simulated driving environment. Through the scheme, the test cost of automatic driving is reduced, a technical effect of full automatic driving development and test is achieved, and the assessment of automatic driving is more comprehensive.

The invention relates to a VR technology based automobile driving simulation device. Compared with the prior art, the simulation device of the invention not only gives feedback on the driving operations of the driver but also generates corresponding automobile actions during the driving. The device also dynamically monitors and simulates the state of the driver in the process of driving for reference to a driving action analyzing result. In addition, a VR simulation technology is used to replace the planar display of a driving scenario, and generates in real time a simulated scenario and road condition according to the angle of the eye view of the driver so that the driver can have truer feelings. And therefore, the operation intentions and the real actions under different road conditions of the driver can be reflected more truly. To a larger extent, the accuracy for acquiring data in the process of simulated driving can be increased, providing valuable reference to detection and research on the driver's actions.
