Abstract

The drive-by-wire method, which is a vehicle vehicle steering method of the vehicle-by-wire steering system, is a manipulator interface that is operated by a driver, such as a slide lever type or joystick type steering signal input device. The steering signal is input to the steering control device through the steering signal cable. The steering control device is a steering method in which steering is performed by controlling a steering device that steers the handle shaft. Since the steering signal input device and the steering control device or the steering device for steering the steering shaft are connected by a steering signal cable, the steering function equipment can be simplified, and the vehicle mounting position as a vehicle steering device is relatively free. Can be set. The steering signal input device can be mounted on the armrest portion of the driver's seat in addition to the conventional steering wheel.

Description

  The present invention is an automobile vehicle steering apparatus. From the early days, as a steering method for automobile vehicles, the tire mounting shaft angle was moved to the left and right so that the vehicle would run along the road, but the driver as a man-machine interface between the vehicle and the driver at that time Is equipped with a handle to steer. Since the vehicle is self-propelled using the engine as power, it is necessary for the passenger to steer the traveling direction of the vehicle along the road. In recent years, an auto-driving automobile vehicle has been studied, but the steering method of the automobile vehicle is a steering wheel rotation operation obtained by a method in which the driver rotates the circular handle left and right in most cases. Is converted to the left-right angle of the mounting shaft of the steering wheel that is the front wheel. In the present invention, instead of using the conventional steering wheel, the steering control lever newly installed at the armrest position of the driver's seat is steered left and right, and the steering signal is transmitted to the steering control device through the steering signal cable to control the steering. In this method, the vehicle is steered by controlling a steering motor of a steering device that is newly installed on the handle shaft portion from the device. Instead of directly steering the handle left and right with the hand as in the prior art, this is a method of steering the handle shaft with a steering device equipped on the handle shaft. A drive-by-wire (Drive By Wire) vehicle that is an alternative to the handle that is a man-machine interface equipment when steering a conventional automobile vehicle, and is completely different from the concept of using the handle that is a conventional vehicle steering method. A steering method and a drive-by-wire vehicle steering apparatus.

  2. Description of the Related Art Conventionally, there are automobile vehicles, airplanes, trains, ships, motorcycles, bicycles, and the like that need to be controlled by passengers. In the case of an automobile vehicle, a circular handle has been equipped as a steering device since the beginning of the invention of the automobile, and most of the automobile vehicles are currently equipped with power steering as a device that supplements the force necessary to mechanically rotate the handle shaft. Equipped. On the other hand, in the case of airplanes, the functional advancement of steering equipment has already progressed, and the fly-by-wire steering system has been adopted from the conventional mechanical type as the steering device equipped on the aircraft.

The object of the present invention is to reduce the driver's fatigue when driving on a motorway, and it is possible to drive a car in a posture when sitting on a single sofa with both elbows in a living room at home. It will be.
In the present invention, the driver operates a steering lever and a winker switch that are newly installed in the right or left armrest portion of the driver's seat respectively on the right driver's seat or the left driver's seat of the vehicle, and newly installs in the vehicle through the steering signal cable. A steering signal is input to the steering control device. The steering control device that has received the steering signal detects the driver's steering operation with the steering operation lever, and performs the steering operation by controlling the motor for rotating the handle shaft that the steering device newly equipped on the handle shaft equips. . In that case, it may be necessary to operate the winker device, which is a vehicle equipment, but it is conventionally equipped at the handlebar so that the driver does not have to wake up and operate the winker device In addition to the lever-type blinker switch, an armrest blinker switch is installed on the armrest of the driver's seat.
In addition to the steering operation function, the steering lever switch can be provided with an operation function of accelerating or decelerating during traveling of the vehicle by being formed as an input device that can move back and forth.

FIG. 1 is an example of a steering slide switch that is provided on a driver's seat armrest portion of an automobile vehicle equipped with an automobile vehicle drive-by-wire steering system as an embodiment, and that steers a steering wheel of the vehicle. FIG.

FIG. 4B shows an operation speed ratio or steering wheel operation of the drive motor shown in FIG. 3B which operates corresponding to the operation operation ratio of the steering operation lever shown in FIG. 1 and FIG. It is a figure for demonstrating an angle ratio.
FIG. 5A is a diagram for explaining an optimum shape of a steering wheel, which is a conventional steering device, and FIG. 5B is formed in a shape different from the steering operation slide switch shown in FIG. It is a figure which shows the steering operation control lever which is a grip lever type steering operation part. (C) of FIG. 5 is a figure which shows the armrest blinker switch with which a driver's seat armrest part is equipped among the components of a motor vehicle drive-by-wire steering system.

The vehicle vehicle drive-by-wire steering system according to the present embodiment is a steering slide that is a steering operation lever as shown in FIGS. 1A and 1B, which is mounted on the armrest portion of the vehicle seat. This is a steering method in which the driver steers the vehicle by steering the switch 1 and the steering acceleration / deceleration slide switch 2 or the steering operation control lever 555 as shown in FIG. As shown in FIG. 1, by operating the steering slide levers 1 and 2 slidably to the left (Left), the steering wheel of the vehicle operates in a direction in which the vehicle turns to the left. On the other hand, the steering wheel of the vehicle operates in a direction in which the vehicle bends to the right by operating to slide to the right (Right). In FIG. 1B, in addition to the steering function for steering the vehicle, a steering addition function is provided that can adjust the vehicle traveling speed by forming the steering slide switch so as to be movable back and forth. An example of the deceleration slide switch 21 is shown. When accelerating and decelerating from the current traveling speed while the vehicle is traveling, the acceleration / deceleration operation is performed by sliding the steering acceleration / deceleration slide lever 2 of the steering acceleration / deceleration slide switch 21 forward or backward. Is made possible. Conventionally, a vehicle equipped with an acceleration switch and a deceleration switch that is equipped with a steering wheel unit and performs an acceleration operation operation or a deceleration operation operation from a constant operation speed is also provided. A steering acceleration / deceleration slide switch 21 having an acceleration / deceleration operation operation function for performing an acceleration operation operation and a deceleration operation operation of a vehicle speed is manufactured by each automobile manufacturer. The steering acceleration / deceleration slide switch 21 shown in FIG. 1B is slidably operated to the left (Left) so that the steering wheel steers in the direction in which the vehicle turns to the left, while the right (Right) shown in the figure. ), The steering wheel is steered in the direction in which the vehicle turns to the right, and the vehicle speed is set to acceleration by performing the sliding operation in the forward direction (Fast). The vehicle deceleration setting operation operation is made possible by performing an operation operation that is slid in the forward (Slow) direction. The vehicle operation with respect to the actual acceleration / deceleration operation is gradually accelerated or decelerated during the operation by the steering acceleration / deceleration slide switch 21 and the steering acceleration / deceleration slide lever 2 is moved when the speed reached by the driver is reached. A method of returning to neutrality may be used, or a method of accelerating or decelerating at a constant interval speed every time an operation is performed in the front (F) direction or the rear (S) direction. The speed can be set within a safe range set in advance by the driver using the acceleration / deceleration setting switch, which is a component of the steering operation unit 44 mounted on the console panel 211/298 of the vehicle shown in FIG. It is preferable that The steering acceleration / deceleration slide switch 2 provided in the steering acceleration / deceleration slide switch 21 is operated to accelerate / decelerate in the front (F) direction or the rear (S) direction, and at the same time, steer in the left (L) direction or the right (R) direction. By performing the operation, for example, the vehicle operation operation such as changing the lane while gradually accelerating can be performed only by the steering acceleration / deceleration slide switch 21 without using the accelerator pedal of the driver's seat foot 240.
Steering wheels that are operated by operating the steering slide switch 11 and the steering acceleration / deceleration slide switch 21 or the steering operation control lever 555 are mechanically connected by operating the handle shaft using a conventional vehicle steering operation method. Unlike the method that steers the steered wheels, the drive-by-wire method that controls the steering device by inputting a steering signal from the steering operation lever to the steering control device through the steering signal cable, the weight of the entire steering device is reduced. In addition to the front wheels, the wheels that the vehicle equips with a steering angle that moves to the left and right need not be limited to the front wheels only. Do the steering operation to change the angle of the rear wheel equipped on the vehicle in addition to the front wheel in the same direction as the front wheel, or Steering operation unit for switching whether or not to perform interlocking steering operation with the rear wheel as a steering wheel, in which the rear wheel mounted on the vehicle in addition to the front wheel is operated to change the angle in the opposite direction to the front wheel This can be dealt with by installing a steering wheel selector switch near the steering lever as a component of 45.
(A) of FIG. 2 is a figure for demonstrating the driver's seat of the motor vehicle mounted with the motor vehicle drive-by-wire steering system which is an Example of this invention. Steering slide switch 201, armrest winker switch 202, handle 210, center console panel 211, dashboard 215, windshield 230, shift lever 220, driver seat 250, left armrest 270, right armrest 205, accelerator pedal and brake pedal Or the clutch pedal part 240 is shown. The driver sits on the driver's seat 250 to drive, but when operating the vehicle, the driver 210 and the lever-type blinker switch that has been conventionally provided around the handle are often operated in urban areas where there are many left and right turns. The shift lever 220 or the accelerator pedal unit and the brake pedal unit or the clutch pedal unit 240, but when traveling a long distance on a long straight road without traffic lights or intersections such as an intercity road, keep the traveling lane while maintaining a constant speed. In general, the steering operation is performed so as not to protrude. When driving on a long straight road or a highway for a long distance, the driver cannot always release his hand from the steering wheel 210 in order to keep the vehicle traveling path so as not to protrude from the lane. When driving a car, the driver does not leave the driver's seat and does not move the seat. The only way to move the upper body is to confirm safety before and after the left and right or around the handle 210 and the center console panel 211. It is time to operate the switches equipped in the. In addition, in order for the driver to operate the handle 210 with the driver's seat 250, it is difficult to perform a steering operation when the driver is buckled. Therefore, the seat belt as the equipment of the driver's seat 250 tends to be set relatively loose. When traveling on narrow roads with many left and right turns, it is necessary to confirm safety, so it may not be possible to sit still in the driver's seat 250, but when traveling on long distances such as interurban roads In many cases, it is only necessary to take care that the vehicle keeps the course so that the vehicle does not protrude from the traveling lane, and a large steering operation by the handle 210 is hardly required. Therefore, when driving on a straight road that does not need to turn left or right at the intersection, place both arms on the left and right armrests 270 and 205 of the driver's seat 250 instead of the steering wheel 210, and the driving lane is extended by the steering slide switch 201. Steering operation that keeps the course in place is sufficient, and in the past, it was easier to maintain the posture compared to the case where the steering operation was always performed with the hand placed on the handle 210 during traveling, thus reducing fatigue during traveling I can do it. Since the lane may need to be changed even while traveling on a straight road, the conventional handle 210 can be operated without the driver raising his / her upper body from the seat seat 250 and reaching around the handle 210. In addition to the lever-type winker switch equipped around, the armrest winker switch 202 is newly installed around the armrest 205/270 or the armrest 205/270.
FIG. 2 (b) shows another embodiment of the present invention, and is a view for explaining a driver's seat of an automobile vehicle equipped with an automobile vehicle drive-by-wire steering system that is not equipped with a handle 210. FIG. A driver sitting on the driver's seat 288 without being equipped with the steering wheel 210 that is a conventional steering operation unit is equipped with the steering operation control lever 555. At 282. In addition, the shift lever 220 for switching the drive gear, which is the drive system device shown in FIG. 2A, is also equipped with a drive-by-wire shift operation lever switch 280 that is provided on the armrest 287. The vehicle driving method itself is an automotive vehicle drive-by-wire steering system that is a new automobile vehicle driving device, and since the steering wheel 210 is not provided, the driver's seat can be felt clearly and widely. Some airplanes already use a lever-type control input device that is equipped at the armrest part of the cockpit seat. However, unlike an airplane that steers a vehicle up, down, left, or right, an automobile is steered from side to side. Therefore, it is considered that the steering operation can be performed not only by the steering slide switch 11 and the steering acceleration / deceleration slide switch 21 which are a method using the handle 210 even in the case of an automobile, but also by the steering operation control lever 555 alone. If the steering performance is improved as a man-machine interface and the driver's own steering ability is familiar with the steering method in the vehicle-by-wire steering system, the conventional steering method using the handle 210 is used. There is a possibility of replacing it.
In order for the driver to know the current steering wheel angle, the steering wheel 210 is sometimes difficult to understand, but it is necessary to display the steering wheel angle so that the driver can understand the steering wheel angle. As shown in FIG. 2 (b), the visibility is good so that it can be seen visually on the console panel 290. For example, the steering wheel angle at that time is displayed with a tilted illustration on a liquid crystal display with a simplified tire diagram. Thus, it is considered appropriate to equip the steering display unit 47 with which the driver can know the state of the steered wheel at a glance. Steering wheel angle data necessary for display on the console panel 290 is collected from the steering control device 41 which is a component of the automobile vehicle drive-by-wire steering system. In addition, several operation switches are provided as components of the display device and the steering operation unit 44 provided in the center console panel 298 or the console panel 290. This is a steering wheel state display method for reading the steering operation / steering ratio curve data described in FIG.
The armrest portions 287 and 281 are provided with a handle portion 210 and switches 285 that are conventionally provided around the handle, for example, a wiper switch, a horn switch, a window washer switch, a light on / off switch, and the like 285.
Unlike an airplane, in the case of an automobile, the driver's posture is often shaken back and forth or left and right during a vehicle start operation, a vehicle deceleration stop operation, or a right / left turn. In the past, it was possible to hold on the handle 210 and support it with both arms, but when the handle 210 was not equipped, the seat shape that wrapped and supported the driver's body and the armrest shape that was easy to hold by hand or the body held well When checking the front, rear, left and right safety, it is necessary to deal with it by devising a seatbelt function that easily tilts the upper body forward.
FIG. 3A shows a state in which the steering shaft 321 is mounted on the handle shaft 320 on which the handle 310 is mounted. In practice, the handle shaft 320 is fixedly mounted on the vehicle side. It is. FIG. 3B is a diagram for explaining the internal structure of the steering device 321 shown in FIG. 3A, and includes a handle shaft 389, a handle shaft gear 385, a steering gear 384, and a steering motor 382. . An input steering signal is transmitted to the steering control device 41 through the steering signal cable when the driver sitting on the driver's seat 250/288 steers the steering slide switch 201 / steering operation control lever 555 in the left-right direction. The steering control device 41 controls the steering motor 382 based on the steering signal received through the steering signal cable. The power of the steering motor 382 steers the handle shaft 389 through several steering gears 384 that are optimally set to operate the handle shaft gear 385. Conventionally, the driver operates the handle 310 to convert the handle shaft 320 from the steering shaft 320 by the steering device and transmit it to the steered wheels. In this case, the force required to operate the handle 310 is reduced. Power steering was equipped as a device to do. In the vehicle drive-by-wire steering method, as shown in FIG. 3A, the steering device 321 having the components shown in FIG. In the case of steering operation, it is conceivable that the steering device 321 that is not used becomes a load on the contrary, and the operation force supplemented by the power steering having the function of supplementing the force for operating the handle shaft 320 is optimally adjusted. There is a need. When the load of the steering device 321 when not operating is large, when the steering motor 382 is operated by operating the steering operation lever at the steering gear 384 and the handle shaft gear 385 provided in the steering device 321. Only the operation operation may be determined, and the steering gear mechanism structure 384 in which the steering gear 384 moves and moves may be used. As an example, the steering power machine equipped with the steering device 321 has been described in the case of the steering motor 382. However, the steering power machine need not be limited to the steering motor 382, and transmits the power of the hydraulic steering power machine to the steering gear 385. The method may be used.
FIG. 4A is a block diagram for explaining an automobile vehicle drive-by-wire steering system according to the present invention. MPU 40, which is a centralized control device for controlling the entire automobile vehicle, a steering slide switch 11 and a steering acceleration / deceleration slide switch that a driver sitting on a driver's seat 250/288 is equipped on armrest portions 270/205/281/287 21 or when the steering operation control lever 555 is operated, the steering signal is transmitted to the steering control device 41 through the steering cable, and the steering motor 382 included in the steering device 382 provided on the handle shaft 320 is controlled by the steering control device 41. The mounting position of the steering control device 41 may be the steering device 46 provided on the handle shaft 320 or the MPU 40 that is a centralized control device that controls the entire vehicle. The driver operates the armrest winker switches 202 and 289 provided in the armrest portions 270, 205, 281 and 287 of the driver seats 250 and 288, and inputs a winker control signal to the direction indicator control section 42 through the winker cable. The direction indicator control unit 42 controls the operation of the blinker devices of the left and right vehicles. A speed control unit 43 that receives a speed setting signal input by a driver operating the steering acceleration / deceleration slide switch 21 and sets a traveling speed while transmitting and receiving a speed control signal to and from the MPU 40. Steering slide switch 11, Steering acceleration / deceleration slide switch 21, Steering operation control lever 555, Steering wheel changeover switch, Steering operation unit 45 as center console panel operation units 211 and 298, Direction indicator operation as armrest winker switches 202 and 289 Part 42, steering device 46, which is a functional equipment for steering the steering shaft 320, a console panel 290 for displaying a steering wheel state display, a center console panel 298 for displaying a steering operation steering operation ratio curve, and a driver of the vehicle For example, a speed setting unit 48 that is a steering acceleration / deceleration slide switch 21 having a function of inputting a speed setting signal when setting a traveling speed is set in a vehicle equipped with a vehicle-by-vehicle drive-by-wire steering system. Luck as a way to do In addition to adjusting the speed by using an accelerator pedal and a brake pedal provided in the foot pedal portions 240 and 295 of the seat seats 250 and 288 or a speed setting switch 501 that has conventionally been provided in the handle portion 210 and the like, the driver seats 250 and 288 For example, a steering acceleration / deceleration slide switch 21 provided with a speed setting function in the armrest portions 270, 205, 287, and 281. Alternatively, when actually formed, as shown in FIG. 5B, the device is formed in the form of a joystick type input device equipped with several input switches which are man-machine interface input devices of a computer, for example. This is a component when a steering operation control lever 555 equipped with several button type switches or left and right seesaw type input switches equipped on the steering operation control grip 507 is equipped. Conventionally, since there is a vehicle in which a speed setting switch is provided on the handle portion 210, it is considered that it is practical to equip the MPU 40 with the control function portion of the speed setting portion 48. The power supply unit 49 supplies power to each component, and a battery equipped in the vehicle is a power supply.
FIG. 4B shows a steering operation / steering operation ratio curve indicated by a steering device operation ratio (Y axis) with respect to a steering operation device operation ratio (X axis) of an automobile vehicle drive-by-wire steering system according to the present invention. It is a figure for demonstrating. The steering operation device operation ratio (when the driver performs the steering operation by the steering slide switch 11 shown in FIG. 1A and the steering acceleration / deceleration slide switch 21 shown in FIG. 1B or the steering operation control lever 555 ( The steering wheel operating angle ratio (Y axis) with respect to (X axis) is shown.
The X axis is the steering slide switch 11 and the steering acceleration / deceleration slide switch 21 shown in FIG. 1 or the left side of the steering operation control lever 555 shown in FIG. The steering operation ratio of the steering device 47 whose shaft operates correspondingly is shown. When the steering slide switch 1 or 2 or the steering operation control grip 507 is steered in the left-right direction indicated by the X axis, the steering operation ratio of the steering device 47 is represented by a steering operation steering ratio curve as a proportional curve. Can do.
In the case of the steering slide switch 11 and the steering acceleration / deceleration slide switch 21, a method of controlling the steering motor 382 provided in the steering device 46 is suitable because the left and right movable distances of the steering slide lever 1 and the steering acceleration / deceleration slide lever 2 are short. It is thought that. When the steering slide levers 1 and 2 are operated to the left and right, the steering motor 382 operates at the operation ratio of the steering operation steering operation ratio curve indicated by the solid line of the graph shown in FIG. When the steering motor 382 is operated, the steering wheel 210 is also rotated at the same time, but when the steering operation is performed while adjusting the operation of the steering motor 382 with the strength of the operation of the steering slide levers 1 and 2, the steering operation is performed up to the necessary steering operation. Thus, if the operation is continued as it is, the Y-axis is 100%, and the steering operation is performed until the handle 210 is fully turned. Therefore, the steering slide levers 1 and 2 are returned to neutral. That is, when the handle 210 is operated, the hand is released from the handle 210. Since the operation of the steering motor 382 is stopped while the vehicle is running and the steering wheel is steered, the steering wheel returns to the straight traveling state naturally. Depending on the vehicle speed at that time and the required travel curve, whether the steering slide levers 1 and 2 can remain neutral and if it is necessary to maintain the curve travel, the steering operation is performed as necessary or When the vehicle is quickly returned to the straight traveling state, the steering slide levers 1 and 2 are operated in the direction opposite to the direction in which the steering operation has been performed earlier so that the reverse rotation operation is performed to return to the straight traveling state even when the handle 210 is operated. As a result, the steered wheel quickly returns straight. When steering is performed with the steering slide levers 1 and 2 provided in the steering slide switch 11 and the steering acceleration / deceleration slide switch 21, the steering operation is performed from the neutral position indicated by the X axis “0” as indicated by the solid line in FIG. A steering operation by the steering motor 382 is performed only in the direction.
On the other hand, the steering method in the case of the steering operation control lever 555 is a grip lever type, and it is possible to ensure a relatively movable distance from side to side, so there is a method of steering corresponding to the steering wheel operating angle ratio as the Y axis. It seems possible. As shown by a dotted line in FIG. 4B, the steering wheel angle (Y axis) corresponds to the operation ratio (X axis) of the steering operation control grip 507 as indicated by the steering operation steering operation ratio curve. The steering wheel angle when the steering operation control grip 507 is held at a constant operation operation ratio (X-axis) holds the constant steering wheel angle (Y-axis) corresponding to the proportional curve. The steering wheel status is displayed on the console panel 290, which is the steering display section 47, with a simplified illustration of the tire so that it can be easily understood visually, so even if the steering wheel 210 is not equipped, the status of the steering wheel at that time can be confirmed. is there. In the case of the steering wheel 210 operation, the steering wheel 210 is steered to some extent and the position is held by hand. On the other hand, in order to return the steered wheel in the operating state to the straight traveling state, the steering operation control grip 507 is changed from the state of the steering wheel operating ratio (Y axis) corresponding to the current operating operation ratio (X axis) to the straight traveling state. When returning to a certain Y-axis “0”, as in the case of steering operation with the handle 210, a method of releasing the hand from the steering operation control grip 507 and returning the steering wheel to the straight traveling state naturally, or the steering operation control grip 507 in the neutral position. In the case of performing an operation operation for returning to a certain operation operation ratio (X axis) toward “0”, the steering control device 41 reversely rotates a steering motor 382 provided in the steering device 47, and the steering wheel is in a straight traveling state of the steering wheel. The steering wheel returns to the straight traveling state while following the steering operation steering operation ratio curve indicated by the dotted line toward “0” of the operation ratio (Y axis). When performing the steering operation with the steering operation control grip 507 described, the steering control device 41 determines the vehicle speed at that time, and performs the steering operation steplessly in a range where the vehicle does not exceed the limit value of the driving performance. Steering motion ratio curve is variably set. For example, when the vehicle speed is low, the steering operation is performed using a dotted steering operation steering operation ratio curve shown in FIG. 4B, and when the vehicle speed is high, the steering operation steering operation ratio curve shown by a single dotted line is used. It is considered that it is safe in terms of vehicle running to equip the steering control device 41 with a function for variably setting a steering operation steering operation ratio curve that is optimal for the current speed so as to perform a steering operation. When the vehicle speed is high, the rudder can be prevented from being excessively effective by a slight operation of the steering operation control grip 507. As another possible safety function, the steering operation control grip 507 of the steering operation control lever 555 operates lightly when the vehicle speed is low, and the force necessary for the steering operation when the vehicle speed is high. It is conceivable to equip the steering operation control lever support 509 with a function that makes the operation of the steering wheel heavy.
As described above, in the case of the steering operation control lever 555, a steering operation device of an automotive vehicle drive-by-wire steering system is assumed instead of the handle 210 which is a conventional steering operation device. 11 and the steering acceleration / deceleration slide switch 21 alone are not assumed as a substitute for the conventional handle 210, but are used in combination with the handle 210 to support the steering so that it does not protrude from the travel lane when traveling straight ahead. It is considered realistic to assume a steering operation function. Therefore, when the driver is performing the steering operation with the steering slide switch 11 and the steering acceleration / deceleration slide switch 21, the driver needs to be able to reach the handle 210 immediately and switch to the steering operation using the handle 210 at any time. . When a large steering operation is necessary, the steering operation is performed on the handle 210 side.
The steering wheel steering operation ratio curve is set so that the steering wheel operation ratio increases or decreases in a proportional curve rather than linearly in proportion to the steering operation operation ratio. This is to prevent over-sensitivity. This is to prevent the driver from being nervously stressed when the steering is too sensitive during driving. In addition, it is also for preventing fluttering that occurs from a slight operation of the steering slide lever during straight running. As shown by the solid line in FIG. 4B, the steering motor operating speed ratio (Y axis) with respect to the steering slide lever operating ratio (X axis), or the steering operation control grip 507 operating operation as shown by the dotted and single dotted lines. How to set the steering wheel operation ratio (Y axis) with respect to the ratio (X axis) can be set variably, and the standard steering operation steering operation ratio curve is driven and controlled at the vehicle manufacturing factory when the vehicle is manufactured. It is set in the ROM of the device 41 and stored in the RAM of the drive control device 41 so that the driver can arbitrarily set the operation ratio curve within a safe range on the center console panels 211 and 298 of the driver's seat. The method is appropriate. By doing so, a steering operation region (X-axis) such as a setting for steering operation by small steering operation, a setting for steering operation by large steering operation, or a steering operation setting for reacting sensitively or slowing, etc. Arbitrary settings can be made every time. Alternatively, as shown as an example with a dotted line or a single dotted line in FIG. 4B, it is preferable to provide a functional equipment that variably sets the vehicle speed within a safe range.
FIG. 5A is a view for explaining the shape of the handle 210. Conventionally, the shape of the handle 210 is almost a perfect circle, but there have been a shape different from a perfect circle for racing or sports vehicles. When a driver drives a vehicle equipped with an automobile vehicle drive-by-wire steering apparatus according to the present invention, particularly when a driver is driving a steering operation with the steering slide switch 11 or the steering acceleration / deceleration slide switch 21 in the case of a normal passenger vehicle, It is possible to drive in a posture in which the driver sits deeply on the driver's seat 250 without using the handle 210 and leans against the backrest, or when sitting on a single sofa with both armrests in the living room at home. Accordingly, when looking forward through the windshield 230 from the line of sight of the driver sitting on the driver seat 250 shown in FIG. 2A, the line of sight is necessarily lower than when the body is raised. Therefore, the upper position of the handle 210 may be higher than the upper position of the dashboard 215, and the line of sight may be narrowed. In order to prevent this, a method of providing the handle shaft 320 with a function capable of reducing the diameter of the handle 210 or reducing the height of the handle 210 is conceivable. In the lowering method, the position of the handle 210 becomes too low. Therefore, it is optimal to form a handle shape 505 in which the upper portion of the handle 500 is cut as shown in FIG. In addition, a handle shape 502 in which the lower portion of the handle 500 is cut so that a wide space around the knee of the driver seat 250 when the driver gets on and off the vehicle is preferable. However, since it is not common to form the handle 500 in a shape different from the true circle, it is not common, so it is not a standard equipment as a vehicle specification but an equipment that can be selected as an option as shown in FIG. A handle 500 shape as shown in FIG. In addition, in the figure, a speed setting function switch 501 having an example conventionally provided at the center of the handle 500 is shown.
FIG. 5B shows a steering operation input device formed in a shape different from the steering slide switch 11 shown in FIG. 1A and the steering acceleration / deceleration slide switch 21 shown in FIG. A steering operation control lever 555 having a more advanced steering operation input function. The driver performs the steering operation by operating the steering operation control grip 507 in the left direction or the right direction. The main body portion uses a durable metal material, and the surface of the steering operation control grip 507 is easily adapted to the hand. It is made of a material and is mounted on the armrest portions 281 and 287 beside the driver seat 288 by the steering operation control lever support portion 509. Such a lever-type steering device has been put to practical use in an airplane control device, but in the case of an automobile, unlike an airplane flying in the air, it frequently repeats start and stop or acceleration / deceleration during traveling. Therefore, in the past, the driver was able to support the posture by holding the handle 210, but in the case of the steering operation control lever 555, the driver accidentally supported the upper body in addition to the steering operation which is a functional purpose. It is necessary to have enough durability to withstand the force. For that purpose, in addition to the attachment method of forming the main body of a durable metal material and firmly fixing it, as a method of fixing and attaching the attachment support shaft of the steering operation control lever support portion 509 to the bearing stand side, A steering operation control lever mounting method that absorbs shock and can have a practical durable structure by mounting with a hard spring, hard rubber, or a fixing bracket having an impact absorbing function is conceivable.
Conventionally, the steering control grip 507 is provided as an acceleration / deceleration setting switch 501 on the steering wheel shown in FIG. 5A so that the driver can operate while steering with the steering control lever 555. The steering operation control grip acceleration setting switch 527 and the steering operation control grip deceleration setting switch 529, or the steering operation control grip winker switch 528 are equipped as functions, so that the driver can move his hand from the steering operation control grip 507 while performing the steering operation. It is possible to perform acceleration / deceleration setting and blinker operation without releasing. The steering operation control grip acceleration setting switch 527 and the steering operation control grip deceleration setting switch 529 are push button type input switches, and the steering operation control grip blinker switch 528 is a seesaw type left / right switching type push switch.
Since it is a device configuration in which the steering signal input device and the steering control device or the steering device, which are the characteristics of an automobile vehicle run-by-wire steering system, are connected by a signal cable or a control signal cable, respectively, the mounting position on the vehicle is relatively free. It can be set. Since there are right-handed / left-handed people in automobile vehicles and right-handed or left-handed people in drivers, steering slide switch 11 and steering acceleration / deceleration slide switch 21 which are steering signal input devices as man-machine interfaces or steering The operation control lever 555 or the gear shift operation lever switch 280 of the drive system in the future is equipped so that the equipment position can be set according to the driver side rather than the driver side to the vehicle as in the past. This can be done by mounting the mounting base in advance so that the place can be located on either the left or right side.
FIG. 5C is a view for explaining the operation of the armrest winker switch 202 shown in FIG. 2A and the steering operation control grip winker switch 528 shown in FIG. A switch that operates in a seesaw manner by pressing each of the left and right sides. In the case of the armrest winker switch 202, in addition to the conventional lever-type winker switch provided around the handle 210, the armrest portion 270 of the driver seat 250 is provided.・ Mounted with 205, a vehicle window open / close switch or door lock switch. As an operation method, for example, when the driver operates the left winker device while driving the vehicle, the left indicator (L) 520 of the armrest winker switch 511 is pressed to send the winker operation signal to the direction indicator controller 43 through the winker signal cable. input. The direction indicator control unit 43 makes a judgment based on the winker operating state and the winker operating signal at the time of reception. When the winker operating state is stopped, the blinking lighting operation of the left winker device equipped on the vehicle is started. On the other hand, when the right winker device is operated, the reverse operation is performed. When the left or right side of the armrest winker switch 511 is pressed, the left and right winker devices start blinking and lighting operations. Either the left or the right blinks and the blinker lights up. The blinker device is turned off because the armrest blinker switch 511 and the steering operation control grip blinker switch 528 are pressed once opposite to the currently operated one. Sometimes it turns off. Alternatively, as in the case of the turn-off operation method when the winker device is actuated when turning right or left with the conventional lever-type winker switch installed around the steering wheel, the direction indicator control unit is in the middle of returning the steering operation angle of the steered wheel to the straight traveling state. 43 automatically senses and ends the blinking lighting operation.
Currently, fly-by-wire control devices have already been put into practical use for airplanes, and are operating safely with hundreds of passengers while connecting to the Internet, such as an air traffic control system or the Internet. Even in the case of automobiles, the durability and reliability of the vehicle drive-by-wire steering system itself is completed to a practical level, and a safety level equivalent to or higher than that of an airplane flying with several hundred passengers is secured. There is a need to. In the near future, it is considered that each vehicle will run while being connected to the Internet at all times via the Internet connection or a new automobile vehicle control system. There is a need for a vehicle-by-wire steering system that can fully protect against infringement via the vehicle. Already, an autonomous driving vehicle that automatically travels while confirming a position by GPS, or an autonomous driving vehicle that automatically travels according to a guidance signal from a guide cable embedded in a road has been studied. Considering the near future where each automobile vehicle is expected to be connected to the Internet, a new vehicle for connecting to the Internet, such as considering whether the developer or manufacturer can get on the vehicle and drive normally It is considered necessary to develop vehicle safety standards.
If a bug in the vehicle drive-by-wire steering system itself or a malfunction due to system intrusion from outside the vehicle occurs, the cause can be thoroughly investigated and dealt with in the form of the responsibility of the vehicle manufacturer. Automobile vehicle manufacturers are not likely to manufacture vehicles that would be unable to sell their own cars.
The name of the invention is an automotive vehicle drive-by-wire steering system, but the word drive-by-wire is based on the common name of the fly-by-wire control system, which is a control system already in practical use on airplanes. Since the present invention is an automobile and there is no general name yet, the invention name was applied for the drive-by-wire steering system as a drive-by-wire system.

Conventionally, an automobile has been steered by a steering wheel. Steering with the steering wheel means that the driver can never go away from the steering wheel even when driving on a straight road that does not need to turn left or right. The driving of the car was tired because it had to be.
Equipped with a steering input device for the driver's steering operation on the armrest part of the driver's seat in addition to the steering wheel, the driver can release his hands from the steering wheel and put his arms on both armrests of the driver's seat. Driving is possible and driving fatigue can be reduced.
The steering operation method of an automobile vehicle was held by the existing concept that it was done with a conventional steering wheel, but until it gets used to the steering operation of the drive-by-wire system, the steering operation unit and the handle are used together in the armrest part. If you get used to driving with the equipped steering device and the steering performance of the grip-type steering operation control lever and steering control device or steering device is highly advanced, you do not need to equip the conventional steering wheel and steer with the steering wheel. It is possible to reduce fatigue than the operation method.
It is thought that it will take some years for the driver to drive an automobile with only a grip type steering operation control lever without equipped with a handle, but in the armrest part that is used together with the handle steering part In the case of the equipped steering slide switch, it is not difficult for the driver to perform the steering operation at the steering operation part of the armrest part on the automobile road where the straight line continues. Since the steering signal input device and the steering control device or the steering device for steering the steering shaft is connected by a signal cable, the vehicle mounting position of the steering signal input device is relatively free. Can be set to a vehicle with a right-hand drive specification and a vehicle with a left-hand drive specification, When the driver's dominant arm is right-handed or left-handed, it can be handled by setting the equipment position of the steering signal input device.
