Description

  The present invention relates to an arrangement structure of a controller having an inclination sensor, and in particular, an optimum structure for arranging an inclination sensor, which is one of the arrangement conditions not to be covered with water, at a high place avoiding the center of the floor panel. It is related with the arrangement | positioning structure of the controller provided with the inclination sensor which can implement | achieve.

In a vehicle, an engine and a transmission are controlled by a controller. For example, a transmission controller appropriately controls the operation state of an automatic transmission in accordance with the vehicle situation. The controller for transmission performs neutral control in which the operation state of the automatic transmission is neutral in order to reduce the load and improve fuel efficiency. In the neutral control, the power transmission is cut off in the automatic transmission, and the driving force of the engine is not transmitted to the drive shaft. For this reason, if neutral control is performed in a state where the vehicle stops on a slope or the like and the braking device is not working, the vehicle may move unexpectedly.
In order to eliminate such inconvenience, the controller for the transmission is provided with a tilt sensor for detecting the horizontal state or the tilt state of the vehicle, detects the tilt of the vehicle, that is, the tilt of the road, and tilts like a slope. Neutral control is prohibited under certain conditions.
The tilt sensor basically needs to be provided horizontally in order to detect the tilt with high accuracy. Further, in order to detect with high accuracy while the vehicle is running, it is desirable to attach it to a relatively stable part with as little disturbance as possible. Naturally, the center part (the center of the front, back, left and right) of the floor panel of the vehicle body is the most stable, and is the best position in terms of stability.
Mounting in such a position is disclosed in, for example, Japanese Patent Application Laid-Open No. 2007-147493 (Patent Document 1).

JP 2007-147493 A

However, the central portion of the floor panel is convenient for other devices, and all the devices cannot be concentrated there. Also, in vehicles that provide a flat floor surface that allows a wide space for passengers' footsteps, walk-throughs, etc., such electrical components are placed at the center of the floor panel that becomes the passage. Can not do it. Furthermore, the position where the inclination sensor is disposed is more preferably a position that is hidden in the shadow of other parts at a high location even in a passenger cabin in order to avoid being exposed to water (water is applied).
In addition, it is difficult to change the specification and to change the mounting posture of the controller by incorporating the tilt sensor that needs to be horizontally arranged in the controller. Even if there is a small difference in specifications, there is an inconvenience that it will be a big change, and there is a convenience that you want to keep separately without incorporating it.
Furthermore, a dedicated bracket is required for mounting the tilt sensor alone, and the number of parts increases, resulting in an increase in the total weight of the vehicle. In addition, since the tilt sensor needs to be mounted on a horizontal plane in order to measure the tilt, there are many restrictions on the vehicle layout (being horizontal. Do not get wet. Harness can be connected.) And layout is difficult. . In some cases, it is necessary to provide a large dedicated bracket.
Furthermore, when the inclination sensor is attached alone, the total length of the harness connected to the controller becomes long, and shielded wires are used to prevent inductive noise from other harnesses. However, the shielded wire has a problem of high cost.

  The present invention provides a tilt sensor (or an acceleration sensor) and a controller to which the tilt sensor is connected at a high place avoiding the center of the floor panel, facilitates evaluation using components such as the controller and the tilt sensor, The components (controller and tilt sensor) can be mounted in close proximity with each other, and the wiring of the harness can be simplified (shortening the overall length, omitting shield functions such as magnetic shielding) by close proximity. Objective.

  The present invention includes a tilt sensor that detects a horizontal state or a tilt state of a vehicle, a harness that transmits an output of the tilt sensor, and a controller that connects the harness, and includes a tilt sensor that mounts these at appropriate positions on the vehicle. In the arrangement structure of the controller, a bracket that supports the controller of the housing is attached to the dash side panel of the vehicle, and a support portion is provided on the bracket to support the tilt sensor.

Since the controller and the bracket for supporting the tilt sensor are integrated, the controller arrangement structure including the tilt sensor according to the present invention can be evaluated in a state where the controller and the tilt sensor are partly assembled.
For this reason, the arrangement structure of the controller including the tilt sensor according to the present invention can easily evaluate reliability tests and conformity with components including the controller and the tilt sensor, and can share the bracket for mounting the controller and the tilt sensor. Therefore, weight reduction and cost reduction can be achieved, and since the inclination sensor is not arranged at the center of the floor panel, the passenger compartment floor can be made flat.

It is an expansion perspective view of the controller and inclination sensor which were arrange | positioned at the dash side panel. (Example) It is a perspective view of the controller and inclination sensor which were arrange | positioned at the dash side panel. (Example) It is the perspective view which looked at the controller and inclination sensor which were arrange | positioned in the interior space of an instrument panel from the passenger compartment side. (Example)

In this invention, the controller and the tilt sensor are integrally supported by the dash side panel with the bracket, so that the tilt sensor is supported at a high place so as not to be covered with water while avoiding the center of the floor panel. It facilitates and enables compact mounting and simplifies wiring of the harness.
Embodiments of the present invention will be described below with reference to the drawings.

The left pillar 4 is continuously provided on the left dash side panel 11, and a right dash side panel (not shown) is provided. The right pillar is continuously provided at the top. The left dash side panel 11 and the right dash side panel (not shown) are connected to each other by a cross member (not shown). Therefore, the dash side panel 11 has high rigidity as a structural member.

As shown in FIGS. 1 and 2, the vehicle 1 is equipped with a transmission controller 13 that controls an automatic transmission mounted in an engine room. The controller 13 is connected to the automatic transmission by the main harness 14. The controller 13 includes an inclination sensor 15 that detects a horizontal state or an inclination state of the vehicle 1. The inclination sensor 15 is connected to the controller 13 by a sensor harness 16. In the control, the controller 13 executes and prohibits the neutral control according to the output of the inclination sensor 15.
The controller 13 is generally formed in a flat rectangular parallelepiped casing 17, and includes an upper end face 18 at one end in the longitudinal direction that becomes the upper part of the casing 17, and a lower part at the other end in the longitudinal direction that becomes the lower part of the casing 17. An end surface 19 is provided, and a connecting portion 20 for connecting the main harness 14 and the sensor harness 16 to the lower end surface 19 is provided. The controller 13 is provided with one upper fastening portion 21 on one end side in the longitudinal direction, which is the upper portion of the housing 17, and two lower fastening portions 22 on the other end side in the longitudinal direction, which is the lower portion of the housing 17. .
The tilt sensor 15 includes a rectangular parallelepiped sensor main body 23, the sensor harness 16 is connected to one side in the longitudinal direction of the sensor main body 23, and a mounting portion 24 is provided on one side in the width direction of the sensor main body 23.

The controller 13 and the tilt sensor 15 are supported by the bracket 25 on the dash side panel 11. The bracket 25 is made of sheet metal and includes a main body portion 26 that is longer in the longitudinal direction than the width direction for attaching the controller 13, and an upper leg portion 27 and a lower leg portion 28 are provided at both ends in the longitudinal direction of the main body portion 26. Yes. The bracket 25 is provided with a support portion 29 for supporting the inclination sensor 15 horizontally following the upper leg portion 27. This support part 29 shall be comprised with the bracket 25 and the sheet metal of 1 sheet, or shall be integrated in the shape extended by welding two sheet metal.
The bracket 25 is arranged with the upper leg 27... In a state in which the longitudinal direction of the main body 26 is directed in the vertical direction and the upper leg 27 is inclined to the vehicle front side so that the upper leg 27 is closer to the dash panel 10 than the lower leg 28. The lower leg 28 is fastened and fixed to the upper fixing bolt 30 and the lower fixing bolt 31 of the dash side panel 11 by an upper fixing nut 32 and a lower fixing nut 33, respectively. The bracket 25 is attached to an intermediate height position of the dash side panel 11 by fastening and fixing two upper leg portions 27 and lower leg portions 28 that are spaced apart in the vertical direction. The bracket 25 attached to the dash side panel 11 has a support portion 29 for supporting the inclination sensor 15 disposed horizontally.

The bracket 25 attached to the dash side panel 11 is brought into contact with the main body portion 26 in the longitudinal direction so that the controller 13 is in contact with the upper fastening bolt 21 and the lower fastening portion 22 of the controller 13. 34. Fasten and fix with the lower fastening bolt 35. The controller 13 of the housing 17 is fastened and supported by the bracket 25 at a total of three locations, one at the top and two at the bottom. As a result, the controller 13 of the housing 17 is supported such that the longitudinal direction thereof is along the longitudinal direction of the bracket 25, and the lower end surface 19 of the housing 17 is closer to the dash panel 10 than the upper end surface 18 when mounted on the vehicle. It is inclined and mounted on the front side so as to be separated. Therefore, the lower end surface 19 of the controller 13 is opened toward the worker side, so that the assembling work is easy.
The bracket 25 is attached to the dash side panel 11 in an inclined state, and simultaneously supports the controller 13 of the housing 17 in an inclined state so that the upper part of the longitudinal axis is inclined forward from the vertical. The controller 13 of the housing 17 is supported by the upper leg 27 and the lower leg 28 of the bracket 25 so as to be separated from each other along the plane of the dash side panel 11. The controller 13 supported by the bracket 25 is particularly rigid in the direction of gravity.

The controller 13 of the housing 17 is provided with an inclination sensor 15 that extends to a position facing the upper end surface 18 of the housing 17 when the vehicle is mounted. The bracket 23 attached to the dash side panel 11 is provided with a horizontal support portion 29 at a position facing the upper end face 18 of the housing 17 when mounted on the vehicle (a position corresponding to the upper leg portion 27). The inclination sensor 15 is supported on the support portion 29 by fastening and fixing the attachment portion 24 of the inclination sensor 15 with the attachment bolt 36.
Since the bracket 25 is attached to an intermediate height position of the dash side panel 11, the bracket 25 is attached so as to fit in the internal space of the instrument panel 3 as shown in FIG. 2. For this reason, since the inclination sensor 15 comes to be concealed at a high place, the possibility of being flooded becomes extremely low. Further, since the dash side panel 11 is connected to a cross member (not shown) such as a steering support member, the dash side panel 11 has high rigidity as a structural member, and disturbance is relatively small when the tilt sensor 15 is detected. Furthermore, the controller 13 and the inclination sensor 15 which are component parts of the component are arranged close to each other, so that compact mounting is possible.
The sensor harness 16 extending from the inclination sensor 15 is routed so as to surround the periphery of the controller 13 and is connected to the connection portion 20 of the controller 13. The sensor harness 16 extending from the inclination sensor 15 and connected to the controller 13 is routed so as to be bundled together with the other main harness 14 and supported by the dash panel 10 which is a structural member of the vehicle body via the clamp member 37. Has been.
Since the inclination sensor 15 is disposed at a position facing the upper end surface 19 of the housing 17, the entire length of the sensor harness 16 connected to the controller 13 can be shortened, and a shielded wire is used to prevent inductive noise from other harnesses. There is no need to do. Thereby, the inclination sensor 15 can simplify the wiring of the sensor harness 16 by the proximity arrangement with the controller 13 (shortening of the total length, omission of a shielding function such as magnetic shielding). Further, since the tilt sensor 15 is not provided near the lower end surface 19 of the controller 13, the assembly work for connecting the sensor harness 16 is not hindered.

As described above, the arrangement structure of the controller 13 including the inclination sensor 15 can be evaluated in a state where the controller 13 and the inclination sensor 15 are partly assembled because the controller 13 and the bracket 25 supporting the inclination sensor 15 are integrated. .
For this reason, the arrangement structure of the controller 13 including the inclination sensor 15 can easily perform evaluation (reliability test, conformity) with components (the controller 13 and the inclination sensor 15), and a bracket is attached to the attachment of the controller 13 and the inclination sensor 15. Since 25 can be shared, the weight can be reduced and the cost can be reduced, and the inclination sensor 15 is not disposed in the center of the floor panel 12, so that the passenger compartment floor can be flattened.
The bracket 25 supports the controller 13 of the housing 17 in an inclined state, and has a horizontal support portion 29 that extends to a position facing the upper end surface 18 of the housing 17 when the vehicle is mounted. It is attached to this support portion 29.
For this reason, the arrangement structure of the controller 13 provided with the inclination sensor 15 is provided with the support portion 29 for supporting the inclination sensor 15 on the bracket 25 using the extra space above the casing 17 caused by the inclination. In particular, the height direction can be made compact, and it can be shared with other models by a compact arrangement.
Further, the controller 13 of the housing 17 is inclined so that the lower end surface 19 of the housing 17 is separated from the dash panel 10 from the upper end surface 18 when the vehicle is mounted, and the main harness 14 and the sensor harness are attached to the lower end surface 19 of the housing 17. The sensor harness 16 that has 16 connection portions 20 and extends from the inclination sensor 15 disposed at a position facing the upper end surface 18 of the housing 17 is connected to the connection portion 20.
For this reason, since the arrangement structure of the controller 13 including the inclination sensor 15 is an arrangement in which the controller 13 and the inclination sensor 15 are close to each other, the total length of the sensor harness 16 required for the wiring can be shortened, and the shield wire can be used. Can be unnecessary. Further, the arrangement structure of the controller 13 including the inclination sensor 15 is slightly open toward the side away from the dash panel 10 so that the connection portion 20 can be easily seen, so that the wiring connection work is easy. it can.

  The present invention can easily evaluate the reliability test and conformity of a controller including a tilt sensor, can be reduced in weight and cost, and can be applied to a component that requires a shielded wire.
