Description of drawings
Fig. 1 is an engine thermal management system theory diagram.
Embodiment
Further specify below in conjunction with the mode of execution of accompanying drawing the utility model.
Among Fig. 1; The engine thermal management system comprises fan ECU, drive control module, CAN bus, the Engine ECU and the upper-position unit that link to each other with the CAN bus; The input end of fan ECU is provided with the CAN communication interface and reserves the collection of simulant signal port; Fan ECU is connected on the CAN bus through the CAN communication interface of its input end; Be connected with engine water temperature temperature transducer, intake air temperature sensor, engine speed velocity transducer on the Engine ECU, be connected with and outer water temperature sensor on the reservation collection of simulant signal port of fan ECU, fan ECU output pwm signal is through drive control module control connection radiation fan group; This radiation fan group comprises four radiation fans, and these four radiation fans are installed in the side of engine water tank respectively.Upper-position unit utilizes upper software through the CAN communication interface of fan ECU fan ECU to be carried out parameter calibration, and the parameter of demarcation comprises: fan is opened temperature, fan closing temperature, whether adopts input signal port analogue signal, whether is opened a few transportation work style fans etc.Fan ECU selects the open and close of its input signal source and radiation fan according to the control command of upper-position unit.
Its concrete working procedure is following: after engine start, Engine ECU can be gathered temperature and the rate signal of being measured by engine water temperature temperature transducer, intake air temperature sensor, engine speed velocity transducer in real time.Fan ECU can select its input signal source according to the control command of its upper-position unit; If upper computer selecting CAN communication interface; Then fan ECU can be connected on the car load CAN network through its CAN communication interface, obtains the engine coolant temperature signal, intake air temperature signals and the engine rotational speed signal that are collected by motor; If upper computer selecting is reserved the collection of simulant signal port, fan ECU can reserve collection of simulant signal port processing engine temperature information through it.Fan ECU can handle output pwm signal to these signals, and pwm signal is through the running of drive control module control radiation fan.Upper-position unit is exported the control signal to fan ECU according to the unlatching temperature and the closing temperature of the radiation fan of its setting through the CAN bus, thus the opening and closing of control radiation fan.Fan ECU realizes the stepless change to radiation fan through drive control module, thereby regulates the temperature of motor, makes engine temperature constant in optimum working temperature, and intake temperature is constant in optimum working temperature.
