Abstract

This invention relates to a turbo buffer drive controller and its control method, which comprises one turbo buffer and one connected drive controller and the auto power system. The DSP processor stored procedure executes the following steps: starting to setting quota to testing speed to staring speed lamp to testing the block overflow to controlling the short to open to testing the abnormal current to testing input of ABS to testing constant control to testing the braking input signal to opening relative block and to displaying the output status.

Description

technical field [0001] The invention relates to an automotive electronic product, in particular to an eddy current retarder drive controller and a control method thereof. Background technique [0002] Chinese patent ZL01129767.0 announces a "Adjustment method of eddy current deceleration for vehicles", its purpose is to adjust the eddy current deceleration method for vehicles based on power electronic technology, this method can make the eddy current braking force at almost zero Stepless adjustment is made in the whole range from the minimum value to the maximum value, which is easy to operate and has good stability. The method for adjusting the eddy current deceleration for vehicles using PWM (pulse width modulation) circuit technology is used for deceleration while the locomotive is running, and aims to control the current I of each excitation winding (L) of the reducer used, including the following steps: A. The excitation windings (L) of the reducer used are connected i...
