Problems solved by technology

Two years after the frame car was put into use, the frequency of start-up difficulties in low-temperature winter weather is getting higher and higher, especially in recent years when the outdoor temperature in winter is <12°C (that is, the temperature of the engine module casing is measured by the infrared thermometer). appear, seriously affect the normal driving of the vehicle, but also have a greater safety hazard
Through research and research, it is found that the failure of the frame car to start in low temperature weather in winter is mainly caused by the unstable operation of the engine module in the low temperature state. Even if the engine module is replaced, it is only a temporary solution. Therefore, a new solution is urgently needed to solve the above technology question

Embodiment 1

[0043] Example 1: See figure 1 As shown, a constant temperature device of the present invention that solves the functional failure of the engine control module includes functional systems such as a temperature speed control system, an electronically controlled heating system, a high-temperature automatic cooling system, and temperature monitoring and protection. , high-temperature automatic heat dissipation and temperature monitoring protection and other functional systems are connected in parallel with the battery pack 1, the main power switch 2, the electric control lock fuse 4, and the electric control lock 6 to form a closed-loop control loop; the line 22 has a conductive medium inside; The temperature speed regulating system includes a temperature speed regulating fuse 11, a temperature speed regulating resistor 15, and a heating element 16 sequentially connected in series through lines to form a control loop; the high temperature automatic heat dissipation system includes...

Embodiment 2

[0044] Embodiment 2: In cold weather, after the vehicle (frame car) stops temporarily for about half an hour, the engine module of the frame car is affected by the ambient temperature and the temperature drops. Open the electric control lock, and the temperature sensor will display the detected temperature of the engine module casing on the display; when the temperature of the engine module casing is lower than the low temperature alarm value, the temperature switch (low temperature) will control the low temperature warning light to flash to remind the driver to wait The electronically controlled heating system works; at this time, the electronically controlled heating system is in closed-loop control, the heating temperature is controlled by the temperature adjustment switch, the time relay starts to count down the heating, and the heating element heats up the engine module shell until the temperature of the engine module shell reaches the temperature adjustment switch When th...

Abstract

The invention relates to a thermostat for solving function failure of an engine control module. The thermostat comprises a temperature speed regulation and control system, an electric control heatingsystem, a high-temperature automatic heat dissipation system and a temperature monitoring protection system. The temperature speed regulation and control system, the electric control heating system, the high-temperature automatic heat dissipation system and the temperature monitoring protection function system are connected with a storage battery pack, a power supply main switch, an electric control lock protector and an electric control lock in series and in parallel through a circuit to form a closed-loop control loop, and a conducting medium is arranged in the circuit. According to the technical scheme, the influence of external low temperature on work of electronic components in the engine module is eliminated, and it is guaranteed that an engine can be normally started under the low-temperature condition.

Description

technical field [0001] The invention relates to a control device, in particular to a constant temperature device for solving the function failure of an engine control module, and belongs to the technical field of vehicle control. Background technique [0002] The engine is the power source of fuel vehicles, and the modern engine is completely controlled by its electronic control unit module (hereinafter referred to as the module). Two years after the frame car was put into use, the frequency of start-up difficulties in low-temperature winter weather is getting higher and higher, especially in recent years when the outdoor temperature in winter is <12°C (that is, the temperature of the engine module casing is measured by the infrared thermometer). Appear, seriously affect the normal driving of vehicles, but also have a greater safety hazard. Through research and research, it is found that the failure of the frame car to start in low temperature weather in winter is mainly...
