Description

Technical Field

[0001] The utility model relates to the technical field of autonomous driving vehicles, and in particular to a whole vehicle control system for an autonomous driving vehicle. Background Art

[0002] An autonomous vehicle is a vehicle that can drive itself autonomously by relying on various sensors, cameras, radars and other equipment to perceive the surrounding environment and make decisions and control through a computer system without the continuous intervention of a human driver.

[0003] Autonomous driving has many advantages. It can improve traffic safety and reduce traffic accidents caused by human errors; it can improve traffic efficiency and alleviate traffic congestion through more precise control and route planning.

[0004] The current mainstream self-driving cars still require the driver to be in the driving position when driving, so as to intervene and control in time to avoid danger. During the self-driving, the driver is close to the steering wheel, which limits the driver's activity space and makes it easy for the driver to contact the steering wheel. In addition, the current prompts to the driver after switching the self-driving mode are not strong enough, and confusion of driving modes can easily lead to danger. Therefore, those skilled in the art provide a whole vehicle control system for self-driving cars to solve the problems raised in the above background technology. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Please see attached Figures 1 to 4 As shown, a whole vehicle control system for an automatic driving vehicle in an embodiment of the utility model comprises a foldable steering wheel 1, a steering wheel lifting mechanism 2 is connected below the foldable steering wheel 1, and a steering shaft 3 is connected to the lower end of the steering wheel lifting mechanism 2. The foldable steering wheel 1 can be folded and stowed, thereby changing the form, intuitively reminding the driver that the automatic driving mode is currently in effect, thereby avoiding the driver's misoperation, and at the same time reducing the obstruction of the driver's sight line by the upper side of the steering wheel, making it easier for the driver to observe the instrument and road information. The steering wheel lifting mechanism 2 is used to drive the foldable steering wheel 1 to retract during automatic driving, thereby increasing the activity space in the cab and improving the comfort level, while also reducing the risk of the driver accidentally touching the steering wheel, thereby improving safety.

[0029] The foldable steering wheel 1 includes a mounting seat 11, a fixing sleeve 12 is fixedly connected to the outer side of the mounting seat 11, folding sleeves 14 are slidably sleeved on both ends of the inner side of the fixing sleeve 12, the inner ends of the two folding sleeves 14 are fixedly connected to arc-shaped racks 17, the two arc-shaped racks 17 are staggered, a gear 16 is rotatably connected to the middle part of the inner part of the fixing sleeve 12, the gear 16 is meshed with the two arc-shaped racks 17, when the foldable steering wheel 1 is in use, the two arc-shaped racks 17 are driven to move by the rotation of the gear 16, thereby driving the two folding sleeves 14 to move and be retracted into the interior of the fixing sleeve 12 for folding, the gear 16 is reversed, and the folding sleeve 14 is driven to extend out of the fixing sleeve 12 through the two arc-shaped racks 17, thereby unfolding the steering wheel for easy operation by the driver.

[0030] The steering wheel lifting mechanism 2 includes a shell 21, and a gear sleeve 23 is rotatably connected to the upper side of the inner part of the shell 21. The inner side of the gear sleeve 23 is connected to a threaded lifting shaft 22 through a threaded sleeve. The upper end of the steering shaft 3 is fixedly connected to a spline shaft 5, and the spline shaft 5 extends into the threaded lifting shaft 22 for sliding connection. Through the provision of the spline shaft 5, the threaded lifting shaft 22 and the steering shaft 3 can be telescoped.

[0031] A motor 24 is fixedly connected to the inside of the shell 21, and a gear 25 is fixedly connected to the output end of the motor 24. The gear 25 is meshed with the gear sleeve 23. When the steering wheel lifting mechanism 2 is in use, it is driven by the motor 24 to drive the gear 25 to rotate, thereby driving the gear sleeve 23 to rotate. Since the inner side of the gear sleeve 23 is threadedly connected to the threaded lifting shaft 22, when the gear sleeve 23 rotates, it can drive the threaded lifting shaft 22 to rise and fall, thereby driving the folding steering wheel 1 to rise and fall. Raising the folding steering wheel 1 is convenient for the driver to operate, and retracting the folding steering wheel 1 is convenient to increase the activity space in the cab and improve comfort. At the same time, it also reduces the risk of the driver accidentally touching the steering wheel, which can improve safety.

[0033] A motor 15 is fixedly connected to the middle part of the lower end of the fixed sleeve 12, and the output end of the motor 15 extends into the interior of the fixed sleeve 12 and is fixedly connected to the shaft end of the gear 16. When the foldable steering wheel 1 is unfolded, it is driven by the motor 15 to drive the gear 16 to rotate, thereby controlling the unfolding and folding of the foldable steering wheel 1.

[0034] The two folding sleeves 14 are each provided with a receiving groove 18, and the receiving grooves 18 inside the two folding sleeves 14 are respectively arranged on the inner side and the outer side, respectively corresponding to the two arc-shaped racks 17. By setting the receiving grooves 18, after the folding sleeves 14 are folded and collected, the arc-shaped racks 17 can enter the receiving grooves 18, and will not interfere with the folding sleeves 14 being collected into the fixed sleeve 12.

[0035] Both ends of the fixed sleeve 12 are fixedly connected with an external connection sleeve 13, which is sleeved on the outer end of the connection between the folding sleeve 14 and the fixed sleeve 12. The connection between the folding sleeve 14 and the fixed sleeve 12 is conveniently protected by the external connection sleeve 13.

[0036] The lower end of the steering shaft 3 is connected with a universal joint 4, and the universal joint 4 is used to be connected with the steering mechanism of the vehicle, so that when the foldable steering wheel 1 is rotated, the vehicle can be driven to steer.

[0037] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
