Interlock control system of van-type vehicle

Abstract

The invention discloses an interlock control system in a van. The interlock control system comprises a detection device for the state of a van door, an interlock control device and an engine starter; wherein, when the circuit of the detection device for the state of the van door is closed, the interlock control device can cut off the circuit connection of the engine starter so that the engine starter cannot be started when the van door is in a state of open or is opened. Another interlock control system comprises an engine control device, a power supply device, a van door control device and a van door starter; wherein, the power supply device is provided with a first power supply providing power for a front van and a second power supply providing power for opening or closing the van door; when the engine is in running state, the power supply device cuts off the circuit connection between the second power supply and the van door control device; when the engine is stopped, the power supply device cuts off the circuit connection between the first power supply and the second power supply, thus realizing that the van door cannot be opened when the engine is in running state so as to avoid the occurrence of unsafe situation.

Description

technical field [0001] The invention relates to a control system on a van vehicle, in particular to a control system for interlocking an engine and a compartment door on a van vehicle. Background technique [0002] A wing-type van vehicle is a van-type vehicle whose compartment doors are flying wing doors. When carrying goods, open the two flying wing doors, and the lateral width of the truck can reach 6 meters. If the truck is moved without closing the flying wing door, it is easy to bump into surrounding pedestrians and other vehicles, causing safety accidents. In order to avoid untimely opening of the flying wing door, a buzzer control circuit is installed on the existing vehicle. When the flying wing door is opened, the buzzer control circuit is connected to prompt the driver to stop the vehicle to move the work with a sound alarm. Since opening the flying wing door and moving the vehicle are controlled separately by the driver, a safety accident will occur if the driv...

Problems solved by technology

Then once the buzzer control circuit is forgotten (restored), the alarm function will be lost and a potential safety hazard will be formed.

[0004] The action of opening the flying wing door on the existing vehicle is realized by driving the hydraulic motor and driving the hydraulic pump through the gearbox power take-off on the engine. Therefore, during the opening and closing process of the flying wing door, the engine is always running, causing unnecessary Necessary energy loss
