Description

Technical Field

[0001] The invention relates to the technical field of driving simulators, in particular to a driving simulation device for training vehicle drivers. Background Art

[0002] Simulated driving, also known as driving simulation or virtual driving, allows users to experience a near-realistic visual, auditory, and tactile driving experience in a virtual driving environment. Driving simulations are realistic, energy-efficient, safe, and economical. Unrestricted by time, climate, or location, they offer high training efficiency and a short training cycle, making them widely used in new vehicle model development and driver training.

[0003] According to the driving mode, it is divided into manual and automatic. Manual transmission requires higher coordination ability of hands and feet. The clutch connects and disconnects the engine and gearbox, and mainly cooperates with the gear lever to complete gear shifting. Since students are not proficient in driving skills, it is easy to release the clutch too quickly. This phenomenon will cause vehicle shaking or even stalling in actual driving. Virtual driving cannot simulate the real driving experience and is not conducive to cultivating students' car sense. In addition, if the speed is not well controlled, the steering wheel will be turned too quickly during the turning process, which can easily damage the steering wheel and fail to cultivate students' correct driving. Therefore, it is necessary to propose a simulation driving device with strong authenticity. Summary of the Invention

[0039] How it works

[0040] In step 1, the trainee performs simulated driving according to the content on the display 4, by pressing the clutch pedal 92 to disconnect the engine and the gearbox, using the electronic gear lever 5 to shift gears and switch driving modes, using the brake pedal 6 and the accelerator pedal 7 to control the movement of the virtual vehicle, and rotating the steering wheel 82 to change the driving direction;

[0041] Step 2: When the trainee rotates the steering wheel 82 too quickly and operates improperly, the first gear 83 drives the second gear 84 to rotate. Since the transmission ratio between the first gear 83 and the second gear 84 is less than 1, the speed of the second gear 84 is increased. The inclined surface of the protrusion 85 on the second gear 84 presses the inclined surface of the lifting block 863, causing the lifting block 863 to move upward and trigger the limit switch 862. The limit switch 862 feeds back an electrical signal to the center console 2, and the display 4 reminds the trainee of the improper operation, thereby regulating the trainee's driving behavior.

[0042] Step 3: When turning, the first gear 83 drives the third gear 89 to rotate. When the steering wheel 82 is about to reach its rotation limit, the roller 884 rolls toward the baffle 810. Due to the large deviation between the center line of the inner rod 883 and the inclined surface of the baffle 810, and the elastic force of the first spring 882, the rotation of the third gear 89 is buffered, thereby reducing the impact force of the steering wheel 82 during rotation and protecting the steering wheel 82.

[0043] Step 4. When shifting gears, the clutch pedal 92 drives the first piston 943 to move to the left through the connecting rod 93. The first piston 943 draws air into the piston cylinder 941. When the suction force exceeds the elastic force of the third spring 9463, the second piston 9464 moves to the left, and the number of air intake holes 9462 opened increases to avoid suppressing the swing of the clutch pedal 92. After the gear shift is completed, if the clutch pedal 92 is released too quickly, the elastic force of the second spring 942 pushes the first piston 943 to the right, and the elastic force of the third spring 9463 pushes the second piston 9464 to the right, the amount of air discharged from the air intake hole 9462 decreases, the air pressure in the piston cylinder 941 increases, the pressure switch 945 is triggered, and an electrical signal is fed back to the center console 2. The vibration motor 10 starts to vibrate, and the electric seat 3 vibrates, simulating the shaking in the actual car, making the simulated driving closer to the actual driving.

[0044] The above are only preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention. These should also be regarded as the scope of protection of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent.
