Problems solved by technology

Although the readings of the temperature sensor can indeed reflect the temperature at the location of the temperature sensor, because the temperature sensor is affected by factors such as engine heat radiation and vehicle exhaust in front, its readings often cannot reflect the real temperature of the external environment where the car is located.

Embodiment Construction

[0058] Please refer to figure 1 As shown, the control system 100 of the present invention includes a hardwire signal processing module 2 , a vehicle body network signal processing module 3 , an MCU operation processing module 4 , a signal output processing module 5 and a vehicle body application module 6 . Wherein, the hard wire signal processing module 2 is used to send the processed analog signal (for example, converting the resistance value of the ambient temperature sensor into a voltage value) to the MCU operation processing module 4 . The body network signal processing module 3 is used to send the processed CAN-related signals to the MCU operation processing module 4 . The signal output processing module 5 sends the ambient temperature correction value processed by the MCU operation processing module 4 to the vehicle body application module 6 .

[0059] In the embodiment of the present invention, the acquired signals include two types, one is acquired by sensors, and th...

Abstract

The invention relates to a method for obtaining environmental temperature. The method comprises the steps as follows: (a), beginning; (b), initializing parameters; (c), acquiring a signal; (d), judging the condition of an engine: correspondingly performing actions of 01, 02, 03 and 04 according to different states, wherein the action 01: when a computed value of the current environmental temperature is used as an output value of the environmental temperature of a display; action 02: using the computed value of the environmental temperature of the engine when the engine runs at the last minute as the output value of the environmental temperature of the display; action 03 and action 04: on the basis of considering various interference factors, correcting the preprocessing readings of an environmental temperature sensor to obtain the accurate computed value of the current environmental temperature; (e), assigning: recording the current engine condition to be used for a vehicle state for the next circle; in addition, using the computed value of the current environmental temperature as the output value of the environmental temperature of the display; (f) returning to the step (c), and entering the next circle for computing; and (g), ending. The invention also relates to a control system performing operation by the method.

Description

technical field [0001] The invention relates to a method for obtaining ambient temperature and a control system thereof, which are applied in the field of automobile air conditioners. Background technique [0002] In order to enable people in the car to know the temperature of the external environment, it is usually displayed on the car dashboard. In the prior art, a temperature sensor communicated with the external environment is usually provided at the position of the air inlet at the front end of the vehicle body. Although the reading of the temperature sensor can indeed reflect the temperature at the location of the temperature sensor, because the temperature sensor is affected by factors such as engine heat radiation and vehicle exhaust in front, its reading often cannot reflect the real temperature of the external environment where the car is located. [0003] Therefore, it is necessary to improve the existing technology to solve the above technical problems. Conten...
