Abstract

PROBLEM TO BE SOLVED: To save fuel and to suppress air pollution by providing a seat-leaving detection sensor for detecting that a driver leaves the seat and generating a signal within a driver's seat, and stopping an engine after the lapse of a prescribed time when the seat-leaving detection signal is generated. SOLUTION: A seat-leaving detecting sensor 2 is built in a driver' s seat 1 to output a seat-leaving signal when a driver leaves the driver's seat 1. A reclining sensor 3 is built in a seat back 1a to generate a detection signal when the seat back 1a is tilted backward for resting. A control is performed so as to start the operation of a timer 4 when the signal from the seat leaving detecting sensor 2 or reclining sensor 3 is received and to stop an engine after the lapse of a prescribed time. According to this, when the driver leaves the seat for loading and unloading or the seat back 1a is tilted down for resting, the idling of the engine is automatically stopped to prevent the discharge of exhaust gas.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the case where the driver temporarily leaves the vehicle while the vehicle is idling, or the case where the driver rests by resting the backrest of the driver's seat rearward while the vehicle is idling. The present invention relates to an idling stop device that automatically stops idling of a vehicle in such a case.

[0002]

2. Description of the Related Art It is well known that exhaust gas from automobiles is related to air pollution, and as a countermeasure, there is a campaign to endeavor to stop prolonged idling. This campaign is of great interest, for example, during nap breaks on long-distance trucks and when unloading luggage.

[0003]

[Problems to be solved by this invention]
In many cases, such as during a nap break on a long-haul truck or when loading or unloading luggage, the engine does not stop when it is safe to stop the engine, and it is often idled. In particular, in a large truck having a large displacement, the idling as described above has a high degree of relation to air pollution. However, it was difficult to regulate to stop idling, and voluntary cancellation was also difficult.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems. When the driver leaves the driver's seat, or when the driver rests on the back of the driver's seat, he or she takes a break. It is an object to provide a device in which idling is automatically stopped.

[0005]

An idling stop device for a lorry according to the present invention is provided inside a driver's seat, and when the driver leaves the driver's seat, detects the leaving and generates a signal. It is provided with an unattended state detection sensor and a timer for stopping the engine when a predetermined time has elapsed after starting from a signal from the unattended state detection sensor.

[0006] Further, a reclining sensor for detecting that the backrest of the driver's seat has been tilted rearward is added to stop the engine when a predetermined time has elapsed even during a nap break.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a driver seat, and a backrest 1a is a reclining seat. Reference numeral 2 denotes a leaving detection sensor incorporated in the driver's seat, and is configured to detect a leaving and generate a signal when the driver leaves the driver's seat 1. Reference numeral 3 denotes a reclining sensor built in the backrest 1a, which is configured to detect that the backrest 1a has been tilted backward and generate a signal. Reference numeral 4 denotes a timer which starts operating when a signal is received from the unattended state detection sensor 2 or the reclining sensor 3 and stops the engine when a predetermined time has elapsed.

[0008] According to the idling stop device configured as described above, the driver's seat 1 can be used when loading or unloading luggage.
If you leave from the time, the time to leave from the timer 4 in advance
When the time set in is exceeded, stop the engine idling. Also, when resting by leaning the backrest 1a rearward, idling of the engine is stopped when a predetermined time has elapsed.

According to the above configuration, the engine stops when the driver leaves the driver's seat 1, or when the backrest 1a is tilted rearward to take a break, and the air conditioner also stops at the same time. When taking a break, the driver may not be able to put up with stopping the air conditioner when taking a break by resting the backrest 1a to the rear side. For this reason, when the backrest 1a is tilted rearward, it is desirable to operate the air conditioner with a spare battery according to the signal of the reclining sensor 3.

[0010]

As described above, according to the present invention, idling is automatically stopped when the driver leaves the driver's seat or takes a rest by resting the backrest of the driver's seat backward. So, along with saving fuel,
The degree related to air pollution can be suppressed.
