Abstract

The invention discloses a heater test control device and control method. The heater test control device is electrically connected to an electronic control unit and a vehicle heater, and includes a power supply module, a communication module, an acquisition module, and a control module, wherein the communication module is used to acquire a rotating speed signal and a torque signal of a vehicle engine, acquired by the electronic control unit; the acquisition module is used to collect a current intake air temperature value of the vehicle heater; and the control module is used for acquiring the rotating speed signal and the torque signal of the vehicle engine, and the current intake air temperature value, and is also used to determine the calibrated intake air temperature value according to the rotating speed signal and the torque signal during the overall vehicle performance test and determine the heating state of the vehicle heater according to the current intake air temperature value and the calibrated intake air temperature value. The heater test control device enables the heater to be tested in cooperation with the whole vehicle, and in the performance test of the whole vehicle, the heater can determine the heating state according to the state of the engine of the whole vehicle, and the test data of the heater can be monitored and collected in real time.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of engines, and in particular to a heater test control device and control method. Background technique [0002] Before the cold start of the automobile engine or for a period of time after the cold start, the air input into the engine needs to be heated. In order to heat the intake air of the engine, the air intake heating grill is mostly used to heat the intake air. Therefore, the performance of the air intake heating grill is critical. [0003] In the prior art, a special test bench is basically used for the air intake heating grill test. When the air intake heating grill is tested, the air intake heating grill is placed on the test bench, and the work of the air intake heating grill is manually controlled. state, and measure voltage, current and ambient temperature with a digital display instrument. [0004] However, using the existing test device to test the intake heating gri...
