Problems solved by technology

When the car is wading through the water-logged section, the driver and occupants waded blindly due to the wrong judgment of the depth of the water, the engine was flooded, or the engine was damaged due to the second start of the vehicle after the wading, resulting in the engine connecting rod Deformation, damage to the piston and cylinder, severe cases will cause the engine to be scrapped
Even if the driver has purchased car damage insurance, the insurance company will not pay for the engine damage caused by the second start of the vehicle after wading. huge economic loss

Embodiment 1

[0040] Such as figure 1 As shown, an automatic engine protection system for automobiles after wading includes a power supply I and an engine starting unit. The engine starting unit includes an engine starting circuit connected in series and an ignition switch K3 for controlling engine starting. One end of the ignition switch K3 is connected to the power supply I. Positive pole, one end of the engine starting circuit is grounded, and also includes a water level monitoring control unit that disconnects the engine starting circuit by monitoring the water level. The water level monitoring control unit includes:

[0041] Power supply II that provides electric energy for the electrical components of the water level monitoring control unit;

[0042] The water level sensing circuit that is turned on when the water level reaches the alarm level; the water level sensing circuit includes a low water level monitoring electrode A, a high water level monitoring electrode B, a resistor R1 an...

Embodiment 2

[0050] A method for automatically protecting the engine of an automobile after wading through water as in Embodiment 1, comprising the steps of:

[0051] S1, ignite and start the engine;

[0052] S2, if the water level is lower than the alarm water level, then continue to keep the engine running; if the water level reaches the alarm water level, then enter the S3 step; if the water level is lower than the alarm water level, the resistance between the low water level monitoring electrode A and the high water level monitoring electrode B is relatively low Large, the transistor V1 is in the cut-off state, and the engine continues to maintain the idling start-stop function; if the water level reaches the alarm level, enter step S3; the alarm level is the position of the high water level monitoring electrode B.

[0053] S3. After the water level reaches the alarm water level, the water level sensing circuit is turned on; the water level sensing circuit is turned on by connecting th...

Abstract

The invention discloses an automatic engine protection system after automobile wading. The system comprises a power source I and an engine starting unit, the engine starting unit comprises an engine starting circuit and an ignition switch K3 for controlling starting of an engine, the engine starting circuit and the ignition switch K3 are connected in series, one end of the ignition switch K3 is connected with the positive electrode of the power source I, and one end of the engine starting circuit is grounded. The system further comprises a water level monitoring control unit used for disconnecting the engine starting circuit by monitoring the water level height. When an automobile with the system encounters rainstorm, ponding and other weathers, and once the automobile wades into water and flames out, the automatic engine wading protection system can automatically cut off the engine starting circuit by autonomously judging the driving state of the automobile, and damage caused by manual starting or autonomous secondary starting in the wading state of the engine is avoided. The automobile engine is protected, the service life of the automobile is prolonged, meanwhile, and the system is widely applicable to all traditional automobiles and new energy automobiles and is also applicable to other engines without start-stop technologies. The coverage is wide, and the cost is lower.

Description

technical field [0001] The invention belongs to the field of engine protection, and in particular relates to an automatic engine protection system and method for an automobile after wading through water. Background technique [0002] With the development of automobile technology, the extensive use of new energy and intelligent control technology, through the induction equipment and intelligent control system, the service life of the vehicle can be extended while ensuring the safety of the vehicle. Among them, automobile wading has potential safety hazards and causes relatively large property losses. [0003] Especially in the south, heavy rainfall such as heavy rain is prone to occur, and it is easy to accumulate water in low-lying areas, causing many drivers to turn off their engines due to blind wading when driving. When the car is wading through the water-logged section, the driver and occupants waded blindly due to the wrong judgment of the depth of the water, the engin...
