Description

The present invention relates to a display device for a hybrid vehicle having a motor and an engine.

The hybrid vehicle has a motor and an engine as a driving force source for traveling. The traveling mode includes an EV (Electric Vehicle) mode in which the driving wheels are driven only by the motor, and an HV (Hybrid Vehicle) mode in which the driving wheels are driven by the motor and the engine.

Japanese Unexamined Patent Publication No. 2009-143553

In the hybrid vehicle, when the vehicle starts, the vehicle travels in the EV mode, and then, depending on the vehicle conditions, the engine is started and the hybrid vehicle travels in the HV mode. In such a hybrid vehicle, the display device is designed to indicate to the driver whether the vehicle is traveling in the EV mode or the HV mode. For example, in Patent Document 1, two pointers are used, one pointer 2 indicates the current rotation speed, and the other drag instruction needle 5 indicates a bow-shaped region 6 capable of traveling in EV mode. Indicates to the driver that the vehicle is traveling in the EV mode if it is within the range of the bow-shaped region 6, and that the pointer 2 is traveling in the HV mode if it is outside the range of the bow-shaped region 6.

However, for example, when the pointer 2 is located near the boundary portion between the bow-shaped region 6 formed by the drag indicator needle 5 and the outside of the range of the bow-shaped region 6, the two pointers 2 and 5 overlap each other. Therefore, at first glance, it is difficult for the driver to determine whether the vehicle is currently traveling in the EV mode or the HV mode.

Although a hybrid vehicle will be described here as an example, it may be a plug-in hybrid vehicle that can charge a driving battery with a commercial power source from the outside.

[Example 1]
FIG. 1 is a block diagram illustrating a hybrid vehicle. Further, FIG. 2 is a diagram showing a display device of the hybrid vehicle of this embodiment.

In this embodiment, the hybrid vehicle (hereinafter, vehicle) 10 has a motor 11 (motor) and an engine 12 (internal combustion engine) as a driving force source for traveling. The motor 11 may be configured to drive the front wheels or the rear wheels, or may be configured to provide a plurality of motors 11 to drive the front wheels and the rear wheels, respectively. Further, the engine 12 may also be configured to drive the front wheels or the rear wheels, or may be configured to drive the front wheels and the rear wheels. Further, the vehicle 10 may have a generator (not shown) that is driven by the engine 12 to generate electric power.

The vehicle 10 has a first mode in which the engine 12 is stopped and the drive wheels are driven by using the motor 11, and the engine 12 is operated so that, for example, the motor 11 and the engine 12 drive the drive wheels. It has a second mode to drive.

Further, the vehicle 10 has an ECU (Electronics Control Unit) 20, and the ECU 20 includes a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), an input / output circuit, and the like.

Then, the signal value from the motor 11 (motor rotation speed, motor output, etc.) and the signal value from the engine 12 (on / off, engine rotation speed, engine output, etc.) are input to the ECU 20. Further, the signal value (SOC (State of Charge), battery output, etc.) from the driving battery 13 that supplies electric power to the motor 11, the signal value of the vehicle speed sensor 14 that detects the vehicle speed, and the accelerator opening that detects the accelerator opening. The signal value of the degree sensor 15 is also input to the ECU 20. The ECU 20 performs arithmetic processing based on the input signal value, and the arithmetically processed arithmetic value is input to the display device 30A.

The display device 30A is a pointer-type instrument that displays an output (hereinafter, traveling output) related to the traveling of the vehicle 10 in the first mode and the second mode described above, and is a so-called meter. As the display device 30A, a mechanical analog meter, a digital meter including a liquid crystal panel, or the like can be used.

As shown in FIG. 2, the display device 30A has a circular instrument panel 35 (display) in which the first region 31A (including the third region 33A) and the second region 32A are arranged and the fourth region 34A is arranged. Region) and one pointer 36 rotatably provided on the instrument panel 35. The guideline 36 indicates a position corresponding to a calculated value input from the ECU 20, and one needle of the pointer 36 indicates the traveling output of the vehicle 10 in the first mode and the second mode.

The first region 31A is an operating region of the pointer 36 when the engine 12 is stopped and the motor 11 is used for traveling, that is, in the first mode, and is a scale region indicating the traveling output in the first mode. .. This first region 31A is about 270 ° to about 30 ° (9 o'clock to 1 o'clock) in the outer peripheral portion on the instrument plate 35, where 0 ° = 360 ° at the 12 o'clock position (top position T of the instrument plate 35). ) Are arranged in a fan shape or an arc shape, and the regions excluding the third region 33A are arranged in a fan shape or an arc shape between the positions of about 270 ° to 0 ° (9:00 to 12:00). Has been done. Further, a dividing line L1 is arranged at a position of 0 ° (12 o'clock), and this dividing line L1 indicates a limit position where the engine 12 is unlikely to start in the first mode. In the following, as the directional expression, either the clock time or the angle at which the 12 o'clock position is 0 ° (= 360 °), or both will be used.

The scale in the first region 31A excluding the third region 33A is a scale indicating the traveling output in the first mode, and the pointer 36 is set to the traveling output between the 9 o'clock and 12 o'clock positions. It points to the corresponding position. The "running output in the first mode" includes, for example, the battery output of the battery 13, the vehicle speed detected by the vehicle speed sensor 14, the accelerator opening degree detected by the accelerator opening sensor 15, the motor rotation speed of the motor 11, and the motor output. Etc. can be used.

The traveling output in the first mode described above may be configured to be selectable by the driver. For example, the display device 30A may be provided with a selection switch (not shown), and by operating this selection switch, one traveling output may be selected from the traveling outputs described above.

For example, when the battery output is selected, the limit battery output at which there is no possibility of starting the engine 12 becomes the position of the dividing line L1, and the pointer 36 indicates the current position of the battery output. Further, when the vehicle speed is selected, the limit vehicle speed at which there is no possibility of starting the engine 12 becomes the position of the dividing line L1, and the pointer 36 indicates the position of the current vehicle speed. Further, when the accelerator opening degree is selected, the limit accelerator opening degree at which there is no possibility of starting the engine 12 becomes the position of the dividing line L1, and the pointer 36 indicates the position of the current accelerator opening degree. Further, when the margin of output of the battery 13 described in the second embodiment described later is selected as the integrated running output, the margin of the limit at which there is no possibility of starting the engine 12 is the position of the dividing line L1. Therefore, the pointer 36 indicates the position of the current margin.

The third region 33A is a guideline when a plurality of conditions for starting the engine 12 are satisfied and the possibility of starting the engine 12 is increased, that is, when there is a possibility of shifting from the first mode to the second mode. It is an operating region of 36, and is a scale region indicating a running output in which the engine 12 may start. The third region 33A is arranged in a fan shape or an arc shape between 0 ° and about 30 ° (12 o'clock position, that is, the uppermost position T to 1 o'clock position) on the outer peripheral portion on the instrument plate 35. There is. A dividing line L2 is arranged at a position (1 o'clock position) of about 30 °, and the dividing line L2 indicates a position where the engine 12 will start when the dividing line L2 is crossed. The third region 33A is arranged in the first region 31A at a location close to the second region 32A, and here, is arranged at a location adjacent to the blank region 34A in the counterclockwise direction.

The scale of the third region 33A is also a scale indicating the traveling output in the first mode, but the traveling output exceeding the traveling output in the region excluding the third region 33A in the first region 31A, that is, that is, It is a scale indicating a traveling output that exceeds the dividing line L1, and the pointer 36 indicates a position corresponding to the traveling output between the positions of 12 o'clock and 1 o'clock.

In the third region 33A, as described above, the engine 12 may start, but the traveling output at the time of starting varies depending on the situation and has a certain range. For example, the movement of the pointer 36 depends on the maximum output of the drive battery 13, and this maximum output increases when charging is performed by regeneration or the like, and if the discharge state continues, the elapsed time thereof. It decreases with it. Due to such a change in the maximum output, the position of the pointer 36 when the engine 12 is started may change. The third region 33A is provided with a predetermined width (here, a width of an angle of 30 °) in the circumferential direction in order to absorb the range of the traveling output in which the engine 12 may start. The predetermined width corresponds to the range of running power that may start.

By providing the third region 33A as described above, the mode in which the engine 12 may start can be indicated in the third region 33A. That is, the engine 12 is started at an arbitrary position in the third region 33A regardless of predetermined conditions such as the maximum output of the battery. As a result, the traveling state of the vehicle 10 becomes easy to understand, the driving output can be correctly grasped by the driver, and the intended driving can be easily realized. Further, the first region 31A including the third region 33A is arranged in a predetermined range, and does not fluctuate as in the bow-shaped region 6 shown in Patent Document 1, which also means that. It contributes to the easy understanding of the traveling state of the vehicle 10.

Further, the width of the third region 33A in the circumferential direction is different from the width of one section of the main scale of the second region 32A in the circumferential direction, and is wider than this width and has a range of 30 ° or more. Here, in the second region 32A, the width in the circumferential direction of one section of the main scale is the width between adjacent ones of the main scale shown by a thick and long line. Here, the numbers for the scale (hereinafter referred to as the scale numbers) are described. Therefore, when the scale numbers are used for explanation, for example, between the main scale of the scale number "0" and the main scale of the scale number "2". It is the width of. As a result, the range in which the engine 12 may start can be appropriately secured, and the movement of the pointer 36 in the range does not give the driver a sense of discomfort.

Further, the third region 33A has a starting point at the 12 o'clock position (the uppermost position T of the instrument panel 35), and is arranged on the right side from that position. That is, the third region 33A is provided on the same side as the second region 32A indicating the second mode with 12 o'clock as a boundary. Therefore, from 12 o'clock on the right side, it is possible to give the driver the feeling that the engine 12 is starting or operating, it becomes easy to grasp the vehicle state, and the operability is also improved.

The second region 32A is an operating region of the pointer 36 when the engine 12 is operated to travel, that is, in the second mode, and is a scale region indicating a traveling output in the second mode. The second region 32A is arranged in a fan shape or an arc shape between positions of about 45 ° to about 130 ° on the outer peripheral portion on the instrument plate 35. In this way, the second region 32A is also arranged in a predetermined range defined in advance. Further, the second region 32A has a plurality of main scales (thick and long lines) and a plurality of sub scales (thin and short lines) arranged between the main scales.

The scale of the second region 32A is a scale indicating the traveling output in the second mode, and the pointer 36 indicates a position corresponding to the traveling output between the positions of about 45 ° and about 130 °. As the "running output in the second mode", for example, the engine speed of the engine 12 or the engine output can be used. Further, the traveling output related to the motor 11 may be included, and in that case, the total output of the motor output and the engine output, the shaft output of the drive shaft of the vehicle 10, and the like can be used.

The traveling output in the second mode described above may also be configured to be selectable by the driver. For example, the display device 30A may be provided with another selection switch (not shown), and by operating this selection switch, one traveling output may be selected from the traveling outputs described above.

For example, if the engine speed is selected, the pointer 36 will point to the current position of the engine speed. If the engine output is selected, the pointer 36 will indicate the current position of the engine output. If the total output is selected, the pointer 36 will point to the current position of the total output. When the shaft output is selected, the pointer 36 points to the current position of the shaft output.

A scale number is indicated on the scale of the second region 32A, and the position of about 45 ° is set to "0", the scale number is increased clockwise, and the position of about 130 ° is set to "10". On the other hand, the scale numbers are not shown in the first region 31A including the third region 33A. Here, since there is no notation of scale numbers in the first region 31A, there is no need to indicate those scales, and for example, only an arc may be used.

In this way, since the scale numbers are written in either the first region 31A or the second region 32A, the first region 31A and the second region 32A are meters showing different traveling outputs. Can be easily understood by the driver. As a result, the traveling state of the vehicle 10 can be easily grasped. In addition, since the scale numbers are written in the second area 32A, the running output in the second mode, that is, the running output related to the engine output can be confirmed numerically, thereby promoting the awareness of eco-driving to the driver. can do.

Further, the start point of the second region 32A (positioned on the scale number of "0") is arranged on the right side of the 12 o'clock position, and the width of the second region 32A indicating the second mode in the circumferential direction is set to the third. By making the first region 31A including the region 33A appear narrower than the width in the circumferential direction, the driver is made aware of eco-driving.

The fourth region 34A has a display form different from that of the second region 32A and the third region 33A. Here, the fourth region 34A is a blank region because the scale is not displayed in the region unlike the second region 32A and the third region 33A. The fourth region 34A is a region provided for clearly separating the first region 31A and the second region 32A in the circumferential direction, and the third region 33A and the second region 32A in the first region 31A It is provided between the positions of about 30 ° to about 45 °, which is within 45 ° from the 12 o'clock position (top position T).

By leaving the fourth region 34A blank as in the present embodiment, the first region 31A and the second region 32A can be more clearly separated in the circumferential direction, and the current driving state for the driver can be determined. It will be easier to recognize. As a result, it is possible to promote awareness of eco-driving among drivers. The fourth region 34A may have a display form different from that of the other regions 32A and 33A. That is, for example, only the fourth region 34A may be colored, or may have a unique pattern.

By arranging the fourth region 34A in this way, the fourth region 34A is separated, and the left and right regions (first region 31A and second region 32A) are different from each other with the fourth region 34A as a boundary. The driver can easily understand that the meter indicates. As a result, the traveling state of the vehicle 10 can be easily grasped. Further, by arranging the fourth region 34A within a range of 45 ° from the 12 o'clock position (top position T), it is possible to appropriately secure the respective display ranges of the first region 31A and the second region 32A. become. That is, for example, it is suppressed that the second region 32A becomes extremely narrow or wide with respect to the other region (first region 31A).

Further, the width of the fourth region 34A in the circumferential direction is different from the width of one section of the main scale of the second region 32A in the circumferential direction, and is also different from the width of the third region 33A in the circumferential direction. Is also narrowed. As a result, it is possible to effectively utilize the space of the instrument panel 35 and prevent the fourth region 34A from being erroneously recognized as a part of the second region 32A or the third region 33A.

Further, the above-mentioned division line L1 divides the region excluding the third region 33A and the third region 33A in the first region 31A, and the above-mentioned division line L2 and the fourth region 34A. Separates the first region 31A and the second region 32A, and separates the third region 33A and the second region 32A. In this way, the first region 31A and the second region 32A are displayed independently of each other. In addition, in order to make the division clearer, the colors for displaying the region excluding the third region 33A in the first region 31A, the third region 33A, and the second region 32A may be different from each other. For example, if the region of the first region 31A excluding the third region 33A is green, the third region 33A is yellow, and the second region 32A is red, the driver can be promoted to be aware of eco-driving. ..

Further, the first region 31A and the second region 32A described above are arranged in a fan shape or an arc shape in a predetermined range, respectively, that is, they are arranged independently in a predetermined range in a similar fan shape or an arc shape. As a whole, they are arranged in a fan shape or an arc shape.

The movement of the pointer 36 accompanying the driving operation of the vehicle 10 will be described with respect to the display device 30A having the above-described configuration.

When the driver starts the vehicle 10, the vehicle 10 first starts traveling in the first mode. Then, while the running output is such that the engine 12 does not start, the pointer 36 stays within the range of the first region 31A excluding the third region 33A according to the traveling output in the first mode. Transition to.

Then, when the traveling output in the first mode exceeds the dividing line L1, the pointer 36 stays within the range of the third region 33A according to the traveling output in the first mode until the engine 12 is started. Transition to. Then, when the traveling output in the first mode exceeds, for example, the maximum output of the battery 13, the engine 12 is started.

Then, when the engine 12 is started, the pointer 36 moves so as to fly from the third region 33A to the second region 32A, and moves within the range of the second region 32A according to the traveling output in the second mode. At this time, the pointer 36 moves to the position of the scale number of "0" which is the starting point of the second region 32A, stops once, and then moves to the position corresponding to the traveling output in the second mode. You can do it. As a result, it is possible to indicate to the driver that the mode has changed from the first mode to the second mode, that is, that the engine 12 has started. After that, the pointer 36 stays within the range of the second region 32A until the engine 12 is stopped.

As described above, in the display device 30A, a number for the scale is indicated on either one of the first region 31A and the second region 32A. In this embodiment, the scale numbers are shown in the second area 32A, and the scale numbers are not shown in the first area 31. According to this, the driver can easily understand that the first region 31A and the second region 32A are meters showing different traveling outputs, and as a result, the traveling state of the vehicle 10 can be easily grasped. can do. In addition, since the scale numbers are written in the second area 32A, the running output in the second mode, that is, the running output related to the engine output can be confirmed numerically, thereby promoting the awareness of eco-driving to the driver. can do.

Further, the display device 30A can indicate the first mode when the engine 12 is not started in the first region 31A (particularly, the region excluding the third region 33A), and the driver can see the first mode. It is possible to clearly indicate that the vehicle can be driven by, so that the driver can continue traveling in the first mode with peace of mind.

Then, since the required output when the engine 12 may start is shown in the third region 33A, it is possible to clearly indicate to the driver the range in which the engine 12 may start. Conventionally, the display of the timing at which the engine starts is pinpoint and fluctuates, so that the engine may start even if the driver does not intend to do so. On the other hand, in the present embodiment, the third region 33A is shown as the range in which the engine 12 may start, so that the driver grasps the positional relationship between the third region 33A and the pointer 36, and then The vehicle 10 can be operated. For example, if the engine 12 is not desired to be started, the accelerator opening or the like is operated so that the pointer 36 is within the range of the first region 31A excluding the third region 33A. You can operate to return to.

Then, when the engine 12 is started, the pointer 36 moves from the third region 33A to the second region 32A, so that the driver can recognize that the engine 12 is operating.

The display device 30A having such a configuration makes it easy to understand the traveling state of the vehicle 10, allows the driver to correctly grasp the traveling state, and facilitates the intended driving.
