Example Embodiment

[0036] Example 1

[0037] Such as figure 2 As shown, the method for controlling the power switch of an engineering vehicle according to an embodiment of the present invention includes:

[0038] Step 10: Receive an instruction to turn off or turn on the main power switch from an external terminal;

[0039] In engineering vehicles, there is generally a main power switch, but mechanical switches and electromagnetic switches are mainly used. Both switches require manual operation by the driver, or even manual operation in the cab, which makes the driver busy It’s easy to forget to turn off the main switch at the engineering site, causing the circuit to remain connected. After a certain period of time, the battery will lose power. When the battery is further discharged, the vehicle will not be able to start. When restarting, an external battery or temporary charging is required. Increase labor cost, time cost and reduce work efficiency. In addition, due to the power supply requirements...

Example Embodiment

[0046] Example 2

[0047] Such as image 3 As shown, according to another embodiment of the present invention, a method for controlling a power switch of an engineering vehicle includes:

[0048] Step 20: When the main power switch is in the on state and the vehicle's engine is in the off state, detect the remaining power of the vehicle's battery;

[0049] When the battery power of the vehicle is too low, the vehicle cannot be started. Therefore, by detecting the remaining power of the battery of the vehicle, it can be found whether the battery power is too low in time, so as to take protective measures to reduce the possibility of the vehicle being unable to start and improve the work Efficiency and cost savings.

[0050] In addition, when the engine is started and the on-board generator generates power and can charge the battery immediately, there is no problem of remaining power. Therefore, it is only necessary to detect the remaining power of the vehicle's battery when the main po...

Example Embodiment

[0059] Example 3

[0060] Such as Figure 4 As shown, on the basis of Embodiment 2, the method for controlling the power switch of an engineering vehicle according to an embodiment of the present invention includes:

[0061] Step 30: When the main power switch is on and the engine is off, the control distance between the external terminal and the vehicle is detected;

[0062] After the engine is turned off, if the driver has no special circumstances, he will leave the car for other affairs. Therefore, the distance between the driver and the vehicle will become farther and farther. If it is a movable external terminal, it will also leave the vehicle as the driver carries it. Farther and farther; therefore, by detecting the control distance between the external terminal and the vehicle, the distance between the driver and the vehicle can be judged, and then according to the distance between the driver and the vehicle to determine whether the driver has left the vehicle and whether he h...

Abstract

The invention provides a control method and device of a power supply total switch of a vehicle. The control method of the power supply total switch of the vehicle comprises the steps that an instruction, emitted by an external terminal, for turning off or turning on the power supply total switch is received; and the power supply total switch is turned off or turned on according to the instructionso as to cut off or feed through an external power supply circuit of a storage battery of the vehicle. According to the technical scheme, remote wireless control and automatic control of the power supply total switch of the vehicle are achieved, the possibility of lack of electricity of the storage battery of the vehicle is reduced, then the possibility that the vehicle cannot be started due to lack of electricity of the storage battery is reduced, the working efficiency is improved, in an emergency situation, the power supply total switch can further be turned off through the external terminal, supply of power of the vehicle is cut off, and safety of the vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle control, in particular to a control method and a control device for a main power switch of a vehicle. Background technique [0002] According to the requirements of GB 7258 "Technical Conditions for Motor Vehicle Operation Safety": special school buses should be equipped with a main power switch, and passenger cars with a length of 6 meters or more should be equipped with an electromagnetic main power switch; passenger cars with a length of 6 meters or more should also be equipped with a power switch that can cut off the battery. Manual mechanical disconnect switches connected to all circuits. At the same time, considering the battery loss of the whole vehicle, etc., the general vehicle is equipped with a main power switch. [0003] Such as figure 1 As shown, in the prior art, the general design is to install a main power switch 12 at the output end of the storage battery 14. The main power swit...
