[0065] Based on the above-mentioned first embodiment, the electric cylinder drive control method in this embodiment, in the step S20, specifically includes:

[0066] Step S201: Receive the PWM input signal sent by the front gearbox controller, filter the PWM input signal and output the filtered PWM input signal to the drive module to drive the load electric cylinder.

[0067] It should be noted that the signal processing module receives the input signal sent by the front gearbox controller, performs signal preprocessing on the input signal and outputs the processed input signal to the drive module to drive the load electric cylinder, and the signal The processing module mainly preprocesses the PWM input signal sent by the pre-controller. The signal processing module includes a signal filtering module and a driving module; wherein, the signal filtering module is connected to the front gearbox controller, and is used to receive a PWM input signal sent by the front gearbox contro...

Abstract

The invention belongs to the technical field of automobile automatic speed changers, and discloses an electric cylinder drive control circuit, method and device and an automobile. The circuit comprises a power source conversion module, a signal processing module and a control module. The power source conversion module is used for conducting direct current conversion on the voltage of a whole vehicle storage battery, and the converted direct current is supplied to a front speed changing box controller. The signal processing module is used for receiving input signals sent by the front speed changing box controller, the input signals are subjected to signal preprocessing, the processed input signals are output to a drive module, and a load electric cylinder is driven. The control module is used for collecting drive state information fed back by the drive module, and conducting operation treatment, and the processed drive state information is output to the front speed changing box controller. Through the above manner, the technical problem that in the prior art, in a power supply system controller, the power source conversion function and the signal processing function are single in usage and are not integrated is solved.

Description

technical field [0001] The invention relates to the technical field of automatic transmissions for automobiles, in particular to an electric cylinder drive control circuit, method, device and automobile. Background technique [0002] Most of the drive controllers in the existing automotive gearboxes in the market are 12V power supply system controllers, and since most of the gearbox controllers are developed by large-scale supplier platforms, if the development of a commercial vehicle 24V power supply system controller needs to integrate an additional electric cylinder drive unit, the development is more difficult, and the development cycle and cost are also larger. In the existing 12V power supply system controller, the two requirements of power conversion and PWM signal processing have not been integrated at the same time. Most of the power conversion is from 12V to 5V, and 3.3V is used to supply power to chips or sensors. As an enabling signal, it is rarely activated. to...
