appsCAN Throttle Simulator & Control Module Kit

Most vehicles sold today do not have a direct physical connection between the accelerator pedal and the engine's throttle. Instead, command signals from the accelerator pedal are sent to the engine controller and the engine's throttle is controlled by an electric motor. When engines or vehicles are tested in dynamometer cells, it is no longer necessary to have a robot or actuator pushing on the accelerator pedal if these accelerator pedal signals can be simulated.

ECM's appsCAN module simulates accelerator pedal position signals based on CAN commands sent to it from the dynamometer controller, or a voltage input, or a potentiometer input. Up to four analogue outputs and four PWM outputs can be simulated. For fail-safe reasons, all accelerator pedals output at least two signals. Coordination of these signals must be maintained to avoid triggering an engine fault code. ECM's appsCAN module supports synchronous signal operation which maintains coordination of these signals. In addition, all analogue outputs from accelerator pedals are ratiometric. This means that the pedal's analogue outputs must scale with voltage reference(s) sent from the engine controller. ECM's appsCAN module's analogue outputs can be ratiometric based on up to four external measured reference voltages or absolute voltages based on internal references.

ECM's appsCAN module can also serve as a general-purpose four-channel analogue input, four-channel analogue output and four-channel PWM output device. Therefore, other dynamometer and test schedule functions can be controlled using the module.
