Control device for idle-speed starting and stopping system of engine

Abstract

The invention discloses a control device for an idle-speed starting and stopping system of an engine. The control device is characterized by comprising a rainfall sensor and a humidity sensor; the rainfall sensor and the humidity sensor are respectively connected to an idle-speed starting and stopping control unit, control signals can be transmitted to an ECU (electronic control unit) of a vehicle by the idle-speed starting and stopping control unit when current rainfall acquired by the rainfall sensor or the vehicle internal humidity acquired by the humidity sensor is excessively high, idle-speed starting and stopping shutdown signals can be outputted to the idle-speed starting and stopping system by the ECU of the vehicle, and automatic starting and stopping functions can be shut down by the idle-speed starting and stopping system. The control device with the structure has the advantages that damage to the engine due to secondary ignition of the engine under the conditions of wading flameout and starting states of the idle-speed starting and stopping system can be prevented, and the problem of dense mist in an existing vehicle due to the fact that an air conditioner is shut down by an existing idle-speed starting and stopping system can be solved.

Description

technical field [0001] The invention relates to an engine idle start-stop system, in particular to a control device for the engine idle start-stop system. Background technique [0002] With the development of my country's automobile industry, as of the end of 2015, the number of motor vehicles in my country reached 279 million, of which 172 million were automobiles, and the new registrations and annual increments of automobiles both reached the highest level in history. With the increase of car ownership, the energy consumption of motor vehicles and the emission of pollutants in our country are increasing rapidly, which has a bad impact on people's lives. The country has also issued strict vehicle fuel consumption limits and emission limits and other relevant regulations. In response to national regulations, vehicle manufacturers have added some new technologies to reduce fuel consumption and emissions, such as: idling start and stop, shift reminders, braking Energy recover...

AI Technical Summary

Problems solved by technology

[0004] However, when there is heavy rainfall and serious water accumulation, when the vehicle passes through the waterlogged section, if the idle start-stop system continues to work when the engine is flooded, it will cause engine pistons and cylinders to wear out, and in severe cases even lead to engine failure

At the same time, when the temperature difference between the inside and outside of the car is large, after the engine is turned off by the idle start-stop system, the air conditioner may not work, causing fog on the windshield

[0005] In view of the above problems, a new type of control device is provided to avoid damage to the engine caused by the idling start-stop system under special circumstances
