Embodiment 1
[0054] A method to prevent the impact of the action of the air conditioner compressor on the gear shift, which is applied to the vehicle controller, refer to image 3 , the method includes:
[0055] S302. Obtain a shift progress signal sent by the automatic transmission;
[0056] In the embodiment of the present invention, the method is executed by the vehicle controller. Specifically, the method is realized by software, and the software is set on the vehicle controller.
[0057] When the automatic transmission shifts gears, it will send a shifting process signal to the CAN network.
[0058] The vehicle controller can obtain the shift progress signal sent by the automatic transmission from the CAN network.
[0059] S304, judging the shift state of the automatic transmission according to the shift progress signal, wherein the shift state includes: a state of shifting, a state of completion of shifting;
[0060] After the shift progress signal is obtained, the shift state of...
Embodiment 2
[0093] A device that prevents the impact of the action of the air-conditioning compressor on gear shifting. It is applied to the vehicle controller. Refer to Image 6 , the device consists of:
[0094] An acquisition module 11, configured to acquire the shift progress signal sent by the automatic transmission;
[0095] Judging module 12, used for judging the shift state of the automatic transmission according to the shift progress signal, wherein the shift state includes: the state of shifting, the state of complete shift;
[0096] Release the control module 13, if the automatic transmission is in the state of complete shifting, then release the control of the air-conditioning compressor, so that the air-conditioning compressor acts according to the action signal sent by the target device;
[0097] The control module 14, if the automatic transmission is in the state of shifting gears, then controls the air conditioner compressor to maintain the current state until the automatic...

Abstract
The invention provides a method and device for preventing the impact of an air conditioner compressor on gear shifting. The method comprises the steps that a gear shifting process signal sent by an automatic transmission is acquired; according to the gear shifting process signal, a gear shifting state of the automatic transmission is judged; if the automatic transmission is in a state of gear shifting completion, the control over the air conditioner compressor is removed to make the air conditioner compressor carry out movements according to an action signal sent by a target device; if the automatic transmission is in a state of gear shifting, the air conditioner compressor is controlled to keep a current state until the automatic transmission enters into the state of gear shifting completion. The method can prevent the action of the air conditioner compressor during the gear shifting of the automatic transmission, so that the impact of the gear shifting can not occur during the gear shifting of the automatic transmission, the gear shifting quality of the automatic transmission is ensured, and the technical problem of the poor gear shifting quality caused by the gear shifting impact during the gear shifting of the automatic transmission is solved.
Description
technical field [0001] The invention relates to the technical field of gear shifting of automatic transmissions, in particular to a method and device for preventing the impact of the action of an air conditioner compressor on gear shifting. Background technique [0002] Turning on and off of the air conditioner compressor will have a significant impact on the engine load, and if the air conditioner compressor (abbreviated as AC) operates during the shifting process of the automatic transmission, it will affect the shifting quality of the automatic transmission. [0003] Such as figure 1 with figure 2 As shown, when the AC is turned on, the engine torque will increase by about 10N·m, and when the AC is turned off, the engine torque will decrease by about 10N·m. Shock occurs and shift quality is poor. [0004] If the AC is not controlled during the shifting process, it will easily cause the following defects: (1) AC opening and closing during the shifting process will caus...
