Abstract

The invention discloses a back accelerator electric control method. When component maloperation or line short or disconnection happens in a standard control unit, a first back accelerator, a comparing control unit and a second back accelerator, a standard control signal forwarded by the first back accelerator forwards and / or a comparing control signal forwarded by the second back accelerator will change so that the standard control signal and the comparing control signal cannot keep original proportional relation, at the time, a chassis ECU cannot convert the standard control signal to a control signal and carry out sending, and rotating speed of a chassis engine cannot be driven to be changed. The problem that in the prior art, when component maloperation or line short or disconnection happens in the control units and / or a back accelerator part, the rotating speed of the chassis engine fluctuates, and fuel is wasted is solved.

Description

technical field [0001] The invention relates to the technical field of engineering special vehicles, in particular to a rear throttle electronic control method and system. Background technique [0002] The running state of the bodywork equipment of engineering special vehicles is usually controlled by the chassis engine, and the speed of the chassis engine is controlled by the rear throttle electronic control system. Such as figure 1 As shown, the bodywork control system 100 sends a speed regulation command to the programmable controller 101, the speed sensor 106 collects the current speed of the chassis engine 105, and sends the current speed signal to the isolation / amplification circuit 107 for isolation / amplification, and then the isolation / amplification The circuit 107 sends the isolated / amplified current speed signal to the programmable controller 101 for processing; the programmable controller 101 compares the above processing result with the speed required by the spe...
