Abstract

The invention relates to a drive controller of an eddy current retarder and a control method thereof. It has an eddy current retarder, a drive controller connected to it and a vehicle power supply system connected between the two. The drive controller is composed of several groups of intelligent power modules and short circuit, overcurrent, overvoltage abnormal output The detection circuit is composed of a DSP processor coupled through each bus, a power supply voltage stabilization circuit coupled through the bus, an indicator light output circuit, a synchronous brake indication output circuit, and an input signal module connected through an input device. The execution steps of the program instructions stored in the DSP processor: start → set the rated speed → detect whether the speed is higher than the set speed → turn on the speed ready light → detect whether a certain gear is overcurrent → detect whether a certain gear is open or short circuit → detect whether There is an abnormal current → check whether there is ABS input → check whether it is constant speed control → check whether there is a brake input signal → turn on the corresponding output gear and brake light → display the output status.

Description

technical field [0001] The invention relates to an automotive electronic product, in particular to a drive controller for an eddy current retarder and a control method thereof. Background technique [0002] Chinese patent ZL01129767.0 announces an "Adjustment Method for Eddy Current Deceleration for Vehicles", which aims to adjust the eddy current deceleration method for vehicles based on power electronics technology. This method can make the eddy current braking force almost zero. Stepless adjustment can be made within the full range from the minimum value to the maximum value, which is easy to operate and has good stability. It utilizes PWM (Pulse Width Modulation) circuit technology to adjust the method of eddy current deceleration for vehicles, which is used for deceleration during locomotive driving, and aims to control the current I of each excitation winding (L) of the reducer used, including the following steps: A. Each excitation winding (L) of the reducer used is ...
