Embodiment 1

[0087] Please refer to figure 1 , a kind of automobile air-conditioning control method, comprises the following steps:

[0088] The preset throttle opening state threshold is 16%;

[0089] The throttle position sensor collects the opening state signal of the throttle valve;

[0090] Send throttle opening status signal to PLC;

[0091] The PLC judges whether the accelerator pedal of the car is in the stepped state through the throttle opening state signal;

[0092] If the opening of the throttle valve is less than 16%, it is judged that the accelerator pedal is not in the stepped state, and the PLC controls the operation of the automobile air-conditioning compressor;

[0093] If the opening degree of the throttle valve is greater than 16%, it is judged that the accelerator pedal is in a stepped state, and the PLC controls the automobile air-conditioning compressor to stop.

[0094] In the above automobile air-conditioning control method, by setting a throttle position senso...

Embodiment 2

[0096] Please refer to figure 2 , a kind of automobile air-conditioning control method, comprises the following steps:

[0097] The preset throttle opening state threshold is 16%;

[0098] switch the operation mode of the automobile air conditioner, the operation mode includes the energy-saving mode and the normal mode of the automobile air conditioner;

[0099] When switching to the energy-saving mode of the car air conditioner,

[0100] The throttle position sensor collects the opening state signal of the throttle valve;

[0101] Send throttle opening status signal to PLC;

[0102] The PLC judges whether the accelerator pedal of the car is in the stepped state through the throttle opening state signal;

[0103] If the opening of the throttle valve is less than 16%, it is judged that the accelerator pedal is not in the stepped state, and the PLC controls the operation of the automobile air-conditioning compressor;

[0104] If the opening degree of the throttle valve is ...

Abstract

The invention relates to an automobile air conditioner control method. The method includes the steps of judging whether an accelerator pedal of an automobile is in a stamped state; if the acceleratorpedal is in the stamped state, controlling an automobile air conditioner compressor to be shut down; if the accelerator pedal is not in the stamped state, controlling the automobile air conditioner compressor to run. Whether the automobile air conditioner compressor runs or shuts down is controlled by judging whether the accelerator pedal of the automobile is in the stamped state; when a driver accelerates driving by treading on the automobile accelerator pedal, it can be ensured that the power of the automobile is not reduced and a remarkable fuel saving effect is achieved; when the driver loosens the accelerator pedal, inertia energy of the automobile and sliding energy under the gravity during the downhill driving are made full use of to make the air conditioner compressor run, the inertia of the automobile is subjected to greater resistance and weakened, thus prolonging the service life of a brake disc. Through testing, the automobile air conditioner control method can save fuel bymore than 10%.

Description

technical field [0001] The invention relates to the technical field of automobile energy saving, in particular to an automobile air conditioner control method and system thereof. Background technique [0002] The original automobile air-conditioning system directly controls the operation of the automobile air-conditioning compressor according to the temperature set in the interior of the automobile. No matter what the working condition of the automobile engine is, the air-conditioning compressor is in a continuous running state. [0003] Vehicles driving in the city are restricted by traffic and congested road conditions, and it is difficult to maintain a constant speed. They usually stop and go, and need to keep stepping on the accelerator to accelerate or brake. [0004] When the driver is stepping on the accelerator to accelerate the car, the engine is in a positive load state, and at this time, the torque generated by the engine needs to drive the compressor of the car a...
