Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a shift range display device for an automatic vehicle having at least a parking range, a reverse range, a neutral range, a drive range, and a low range.

For example, in a car equipped with a so-called semi-automatic transmission consisting of a combination of a torque converter and a planetary gear type auxiliary transmission, shifting to the drive range causes the auxiliary transmission to shift to a high gear with a small reduction ratio. However, by shifting to the low range, the auxiliary transmission is switched to a low gear position with a large reduction ratio.

Under normal conditions of use, it is sufficient to use only the drive range, but when a particularly large output torque is required, such as when starting on a hill, switch to the low range and switch from the low range to the drive range when the specified vehicle speed is reached. It is preferable to switch to this mode for stable driving or fuel-efficient driving of the vehicle.

However, especially in this type of automatic vehicle, when starting from the low range, the driver often forgets to switch to the drive range midway depending on the driving situation, resulting in poor fuel efficiency.

This invention was devised in view of these circumstances, and its purpose is to prompt the driver to switch from low range to drive range when the vehicle speed becomes suitable for driving in drive range while driving in low range. There is no need to provide a shift range display device to prompt the driver.

Hereinafter, the present invention will be explained based on embodiments shown in the drawings.

In the figure, 1 is a meter housing that is installed on the driver's seat side of an instrument panel (not shown), and a speedometer 2 is installed in the center of the front of the meter housing 1, and a fuel gauge is installed on the right side of the front of the meter housing 1. 3 and a water temperature gauge 4 are incorporated respectively.

In addition, display sections 5a, 5b, 5c, 5d, and 5e for parking range P, reverse range R, neutral range N, drive range D, and low range L are installed in tandem on the front left side of the meter housing 1, and the transmitter By switching the range (not shown) to each of the ranges, the corresponding display sections 5a, 5b, 5c, 5d, and 5e are lit.

An indicator lamp 60 having an arrow shape pointing from the low range to the drive range and instructing switching from the low range to the drive range is provided between the drive range display section 5d and the low range display section 5e. In addition to providing a switching instruction display section 6, a switch 7a that detects the low range and turns on when switching to the low range, and detects the vehicle speed,
Switch 7b that is turned on when the vehicle speed is above a certain vehicle speed
An output circuit is provided which outputs an output when the vehicle is in the low range and the vehicle speed is above a certain level, and lights or flashes the indicator lamp 60 to give an instruction to switch to the drive range.

In the embodiment shown in the figure, the meter housing 1
The switching instruction display section 6 having an arrow shape pointing from the low range display section 5e to the drive range display section 5d is incorporated between the drive range display section 5d and the low range display section 5e. The indicator lamp 60 that illuminates the display section 6 is installed on the back side of the section 6, and there is also a switch 7a that is turned on when the transmission is switched to the low range, and a switch 7a that is turned on when the vehicle speed detected by the vehicle speed detector exceeds 55 km/h. Switch 7 that turns on when it gets hot
b to the input terminal of the AND circuit 8, and
The indicator lamp 60 is connected to the output terminal of the AND circuit 8, and an output circuit is provided which outputs an output and lights the indicator lamp 60 when the vehicle is in the low range and the vehicle speed is 55 kg/h or more.

The present invention has the above configuration. For example, when the transmission is switched to the drive range D, the display section 6d of the drive range lights up, and when the transmission is switched to the low range L, the display section 5e of the low range lights up. Inform the driver of the current shift position.

Therefore, when driving in low range L, the vehicle speed is 55km/
h or more and both switches 7a and 7b are turned on, the AND circuit 8 is established, and the instruction lamp 60 of the switching instruction display section 6 lights up, prompting the driver to immediately switch to the drive range with an arrow display. It is.

The same effect can be obtained even if the present invention is applied to a fully automatic vehicle, but in this case, when the drive range is used, the speed at which the auxiliary transmission changes from the low gear position to the high gear position Indication lamp 60 at a high speed of
It is more effective to set it so that it lights up.

Further, if an alarm device such as a buzzer is used in addition to the indicator lamp 60, an even greater effect can be obtained.

As described above, according to the present invention, there is provided a switching instruction display unit equipped with an indicator lamp, an output circuit consisting of a switch that is turned on when switching to the low range, and a switch that is turned on when the vehicle speed is above a certain level, and With a simple configuration that lights or blinks the indicator lamp with the output, when the vehicle speed reaches a speed suitable for driving in the drive range when driving in the low range,
Immediately after the two switches are turned on, the instruction lamp lights up or flashes due to the output of the output circuit, instructing and prompting the driver to switch from the low range to the drive range, and the switching instruction display Since the section is located between the low range display section and the drive range display section, and is shaped like an arrow pointing from the low range to the drive range, the driver can see the lighting or flashing of the indicator lamp at a glance. It is possible to immediately switch from the low range to the drive range without losing timing, without having to take time to think about the meaning of the indicator lamp. Therefore, the user never forgets to switch from the low range to the drive range, and the timing of the switch does not go out of order. Therefore, with a simple configuration, it is possible to easily drive the vehicle in a stable manner or in a fuel-efficient manner.
