Abstract
The utility model relates to an electronic water pump controller for an automobile engine. The electronic water pump controller comprises a power module, a main control module, a motor pre-drive module, a CAN bus communication module and a current feedback acquisition module. One end of the motor pre-drive module is connected with a terminal of a brushless direct current motor of the automobile engine, and the other end is connected with the main control module. The power module, the main control module and the current feedback acquisition module are connected through the CAN bus communication module. According to the electronic water pump controller, a traditional mechanical control mode is replaced by the electronic controller, the water pump is controlled flexibly, a motor radiating system is improved, and the electronic water pump controller is energy saving and emission reduction. Besides, the electronic water pump controller can carry an independently researched and developed motor, and utilization costs are greatly reduced.
Description
Technical field
The utility model relates to a kind of car engine electronic control cooling system technical field, is specifically related to a kind of car engine electronic water pump controller.
