Abstract

The invention discloses the field of the engine thermal type, and particularly relates to an engine thermal type platform rotation speed control system and method. The engine thermal type platform rotation speed control system comprises an accelerator pedal signal output end, a PID microprocessor and an electronic switcher. The engine thermal type platform rotation speed control system and methodhave the advantages that voltage signals used for supporting an engine ECU to maintain the rotation speed of the engine in the later stage is directly provided by the PID microprocessor continuously,the feet of testing workers are liberated, the situation that the rotation speed of the engine is unstable due to unstable voltage output is also avoided, the speed is quick, the stability is high, the reliability is good, and the fluctuation is small.

Description

technical field [0001] The invention relates to the field of engine thermal testing, in particular to a system and method for controlling the rotational speed of an engine thermal bench. Background technique [0002] In the automobile engine hot test bench, the operator needs to test the performance parameters of the engine at different speeds. The most conventional method for controlling the change of engine speed is to realize by manual or electric motor control accelerator pedal. However, this method is difficult to achieve stable control of the engine speed due to the mechanical characteristics of the accelerator pedal itself. During operation, the speed will have a certain deviation from the preset value. Contents of the invention [0003] The object of the present invention is to provide a system and method for controlling the rotational speed of an engine thermal stage, which solves the problem that the control of the rotational speed of the engine through the acce...
