The utility model discloses the technical problem that will solve is: the existing remote driving system based on electrical control needs to be designed and installed when the vehicle leaves factory design, so that the existing remote driving system becomes a part of the vehicle, for the vehicle which is sold in the original design and is not provided with the remote driving system, if the remote driving system needs to be reloaded, the structure and the circuit of the vehicle need to be greatly changed, the long-term stability and the safety of the vehicle operation are probably influenced by the large change, and the high cost and the high risk of the change determine that the remote driving function of the vehicle in stock is difficult to realize according to the concept. On the other hand, even if an automobile host manufacturer designs a remote driving function for a newly developed vehicle, the specific technical route of the remote driving system is greatly different in detail due to the fact that different vehicle types need to be matched, so that the existing automobile remote driving system can be designed in one vehicle type set and cannot be compatible with different vehicle types of different host manufacturers.

The utility model provides a system for solve above-mentioned problem's a long-range driving car, the utility model discloses a following technical scheme realizes:

a system for remotely driving an automobile comprises a main control unit, a driving environment information acquisition module and a communication module, wherein the driving environment information acquisition module is used for acquiring driving environment information and sending the driving environment information to the main control unit; the remote driver sends out a driving instruction according to the decoded driving environment information displayed by the remote control unit, the driving instruction is sent to the main control unit through the communication module, and the main control unit sends out a control instruction according to the driving instruction; the mechanical execution mechanism is used for receiving a control instruction of the main control unit and simulating human driving action to act on a corresponding control part of the automobile according to the control instruction so as to finish remote driving action; the mechanical actuator is used for being installed at a position relative to a control position of an automobile.

Example 3

Based on the remote driving system provided by the embodiment 1, the image acquisition module, the sound acquisition module and the mechanical execution mechanism simulate human driving actions as follows:

1. observing motion

The observation actions mainly include: vehicle forward viewing, vehicle side viewing, vehicle rearward viewing, and vehicle dashboard viewing.

The remote control unit displays video picture signals, a driver sends a driving instruction according to the signals, the driving instruction is sent to the main control unit through the communication module, and the main control unit sends a control instruction to the mechanical execution mechanism according to the driving instruction, so that the control action required by the automobile can be effectively obtained.

2. Listening movement

The listening movement, i.e. the transmission of signals between the outside world and the driver by sound, is usually an aid to the observation movement during driving. Specifically, a plurality of groups of sound collection modules can be arranged according to actual requirements; for example, in some special remote driving situations, such as a narrow parking space, the remote driver needs to move the vehicle out of the parking space by repeated small-distance movement, at this time, the warning tone of the reversing radar is very important and main judgment basis, and in this situation, although the vehicle moves at a very low speed, the physical distance between the vehicle and the surrounding environment is relatively small, so the listening action in this situation is also required with low time delay. At this moment, can set up multiunit sound collection module, the position in the car can freely be selected in the setting of multiunit sound collection module, only need consider efficiency, the accuracy that external sound signal collected to and the pleasing to the eye and the succinct of data line wiring in the car, multiunit sound collection module can also open whole or open the part through the main control unit selectivity.

3. Steering wheel turning action

The action of rotating the steering wheel is used for controlling the direction of the vehicle, the simulation can be carried out through the curve reciprocating motion, the power source is provided by a rotating motor, and the power is transmitted by a gear set, a rack, a cam set or a connecting rod. The mounting position can be selected under the steering wheel, between steering wheel and the steering column cover, the power source is installed on the steering column cover by adopting a fastener or gluing mode, the driven piece of the gear, the cam or the connecting rod is installed on the steering wheel by adopting a fastener or gluing mode, and the gear, the rack, the cam or the connecting rod is installed between the power source and the driven piece to ensure the transmission of power.

The technical personnel in the field can have numerous schemes, and can choose or leave according to the specific design details of different vehicles, but in order not to shield the view of an instrument panel, the operation of operating levers on the left and the right of the steering wheel is not influenced, the space occupation is reduced as much as possible, the influence on a driver under the condition of non-remote driving is reduced, and the position arranged under the steering wheel and between the steering column cover is the optimal selection.

4. Retraction and extension action of accelerator and brake

The retraction and release actions of the accelerator and the brake can be simulated through linear reciprocating motion, and different types of linear motors can be selected as power sources for different vehicle details. The power source and the transmission mechanism are arranged in a space below the position of a driver of a vehicle center console corresponding to the throttle and the brake of the vehicle by fasteners or in an adhesive manner at a proper angle. When the linear motor is selected, constraints on the aspects of the load weight, the effective travel, the maximum speed, the maximum acceleration and the like of the linear motor during operation (especially during operation under the limit condition) of an accelerator and a brake of different vehicles need to be considered.

5. Turn on and turn off turn signal lamp action

The action of turning on and turning off the turn signal lamp can be simulated by intermittent reciprocating motion, and the action can also be simulated by linear reciprocating motion or curvilinear reciprocating motion due to the fact that the motion track corresponding to the action is very simple and short.

A linear motor may be mounted on the steering column cover in a position close to the operating rod by means of fasteners or gluing in the corresponding direction of movement, which action can be simulated directly by the linear reciprocating movement provided by the linear motor. The rotary motor can be arranged on the steering column cover close to the operating rod in a corresponding movement direction in a fastening or gluing mode, and the rotary motor is connected with the operating rod through a connecting rod and can also simulate the action.

In addition, the actions of turning on and off the high beam, the actions of turning on and off the wiper, and the actions of turning on and off the water sprinkling can all refer to the implementation manners and structures of the actions of turning on and off the turn signal lamps.

6. Double flashing indicator light on and off actions

The action of turning on and off the double-flashing indicating lamp can be vividly called 'touch action', and in order to complete the action, a hollow covering structure slightly larger than a button of the double-flashing indicating lamp is required to be installed right above the double-flashing indicating lamp in a fastening piece or an adhesive mode, a linear motor is installed inside the hollow covering structure, and the touch action is simulated through the short-distance linear reciprocating motion of the linear motor.

7. Vehicle action initiated by ignition

There are several implementations of the ignition-initiated vehicle action, specifically as two examples:

(1) one is a 'touch action' which is the same as the turning-on and turning-off action of a double-flashing indicator lamp, and the method is a novel vehicle ignition starting mode for starting a vehicle without a key. To complete the action, a hollow covering structure slightly larger than the ignition starting button is arranged right above the vehicle starting button in a fastening or gluing mode, a linear motor is arranged inside the hollow covering structure, and the contact action is simulated through the short-distance linear reciprocating motion of the linear motor.

(2) The other is that a vehicle key is required to be inserted into a lock hole, and the vehicle is started by rotating at different angles. This action can be summarized as a 'plunging action', i.e. a co-operation of a linear movement and a rotational movement. To simulate the action, a hollow covering structure slightly larger than the diameter of the lock hole is required to be installed right above the lock hole of the vehicle lock in a fastening piece or gluing mode, two motors, a rotating motor and a linear motor can be installed inside the hollow covering structure, the rotating motor is close to the lock hole, the linear motor is installed behind the rotating motor, and the rotating motor is connected with a vehicle key in series. The linear motor can push the connecting body of the rotating motor and the car key to do linear reciprocating motion, the part of the car key inserted in the operation of the simulated inserting rotation is simulated, when the linear motor does linear motion to a set position, the rotating motor rotates to drive the car key to rotate, and the part of the rotating key in the operation of the simulated inserting rotation is simulated.

8. Turning on and off headlight action

Turning on and off the headlight may be visually referred to as a 'turn-knob action', and in order to accomplish such an action, a hollow covering structure slightly larger than the headlight switch is installed directly above the headlight switch by a fastener or an adhesive, and a rotating motor is installed inside and connected with the headlight switch, so that the turn-knob action is simulated by the curved reciprocating motion of the rotating motor.

9. Adjusting vehicle gear action

The gear control of the vehicle has various forms, and the common forms mainly include a knob form, a hand gear form and a ground gear form, which are sequentially exemplified as follows:

(1) knob-type gear adjustment action

The realization process of the movement of the gear control in the knob mode is visually summarized into touch and rotation movement, and the realization process of the movement of turning on and turning off the high beam is different from the realization process of the movement of turning on and turning off the high beam in detail but is consistent with the essence. An electromechanical system is used for simulating the action, a hollow covering structure is fixed above the gear knob in a fastening piece or gluing mode, a rotating motor is arranged in the hollow covering structure, and the rotating motor drives the knob to rotate among different positions through a transmission mechanism so as to realize gear shifting.

(2) Gear adjusting action of chest gear

The simulation action of turning on and off the turn signal lamp is the same.

(3) Gear adjustment action of ground gear

1) Straight-row gear with gear lock

Under the condition of setting the ground gear of the vehicle, the implementation process of adjusting the gear of the vehicle can be visually summarized into two parts, wherein one part is 'touch and press motion', and the other part is a gear locking button; the other part is 'linear reciprocating motion' in that the gear lever is moved linearly between different gear positions.

In this case, there are various ways to simulate the pressing action by the electromechanical system, one is to install a small-sized rotating motor under the lock key of the shift lever by a fastener or an adhesive, the rotating motor is connected with the lock button by a small cam in a rope manner, and when the rotating motor rotates downwards, the rotating motor drives the cam and the rope to move downwards, so as to form the pressing effect on the lock key.

Because the straight-line ground rail advancing and retreating rail moves linearly, the straight-line ground rail advancing and retreating rail can be directly driven by a linear motor. Or driven by a rotating motor through a connecting rod.

2) Step or snake-shaped gear

The serpentine gears generally do not have a lock button. The realization process of the action is vividly summarized as 'broken line movement', an electromechanical system is used for simulating the action, the simplest method is that a cam and a connecting rod are used, the cam is driven by a rotating motor, the connecting mode of the contour of the cam and the connecting rod is designed, the broken line of snake-shaped gear shifting is not complicated, and a broken line movement unit meeting most gear shifting scenes can be designed.

3) Electronic gear lever

The electronic lever operates similarly to the inline shift with a lock button, as does the method of simulating the related action with the electromechanical system.

10. Unlocking and locking actions for vehicles

The vehicle is generally provided with an unlocking button and a locking button of the whole vehicle in the vehicle and on a vehicle key.

The realization process of the action of the unlocking and locking button in the vehicle or on the key of the vehicle is 'touch and press movement', and the realization process of the action of turning on and off the double-flash indicator lamp is only different in action size and is consistent in nature. The electromechanical system is used for simulating the action, a motor (a linear motor or a linear motor) is used as power output, a covering or wrapping structure is manufactured in a fastening piece or gluing mode and used for fixing the motor right above a button, then the linear motor directly acts on the button, or a rotary motor acts on the button through a cam to realize touch and press movement so as to simulate corresponding action.

11. Parking brake retraction/extension action

The parking brake, generally called hand brake, is used for providing resistance to the automobile when the automobile is parked, so that the automobile does not slide.

The parking brake retraction and release action can be vividly called 'lifting and releasing action', in order to complete the action, a hollow covering structure slightly larger than a parking switch is required to be installed right above the parking switch in a fastening or gluing mode, a rotating motor is installed inside the hollow covering structure, the rotor of the rotating motor is perpendicular to the installation direction of the parking switch at an angle of 90 degrees, a cam is arranged on the rotating motor, the parking switch is directly used as a driven piece by the cam, and therefore the lifting and releasing action is simulated through the curve reciprocating motion of the rotating motor through cam transmission.

In addition, a more traditional parking brake mode is a mechanical hand brake. The parking brake retraction and extension action of the mechanical hand brake can be vividly summarized into two parts, wherein one part is 'touch and press motion', and the hand brake locking key at the most front end of a mechanical hand brake operating lever is controlled; the other part is 'linear reciprocating motion', after the mechanical hand brake is unlocked, the hand brake operating lever is pushed in an up-and-down direction in a reciprocating mode to achieve parking braking.

The touch-press motion is realized by an electromechanical system, a hollow structure is always required to be installed by a fastener or an adhesive mode to install a motor, and as for the mechanical hand brake locking key, one mode is that the hollow structure is installed at the foremost end of a mechanical hand brake control lever, namely a small cap type hollow extension structure is made for the mechanical hand brake, a rotor of a linear motor is over against the mechanical hand brake locking key, and the mechanical hand brake is controlled by driving the mechanical hand brake locking key through the rotor of the linear motor; the other mode is that the linear motor is arranged on the side surface of a mechanical hand brake control lever, a rotor of the linear motor is parallel to a mechanical hand brake locking key, the rotor of the linear motor and the mechanical hand brake locking key are connected through a connecting rod, and the mechanical hand brake is controlled by driving the mechanical hand brake locking key through the rotor of the linear motor. The two installation modes are vividly summarized, the first mode is that the right front top of the mechanical hand brake locking key is pulled, and the second mode is that the right front top is pulled from the side rear of the mechanical hand brake locking key.

The linear reciprocating motion is realized by an electromechanical system most simply, the lower part of the front end of the mechanical hand brake control lever is only required to be used as a stress point of the linear motor rotor, the stator of the linear motor and the mechanical hand brake control lever are arranged at a certain angle to fix the linear motor on a vehicle body, and the linear motor is fixed on the vehicle body through a fastener or an adhesive mode and is controlled by the linear reciprocating motion of the linear motor rotor.
