Abstract

The invention discloses an inductor voltage reduction drive type eddy current retarder control system based on bias amplification. The inductor voltage reduction drive type eddy current retarder control system based on the bias amplification comprises an eddy current retarder and is characterized by also comprising a singlechip, a power module, a braking pedal, a gear switch, a switching value signal processing unit, a CAN bus data transceiving unit, a braking car lamp driving unit and a pulse bias amplifying unit which are respectively connected with the singlechip, a car main control unit and a trip computer which are respectively connected with the CAN bus data transceiving unit, an inductor voltage reduction drive unit connected with the switching value signal processing unit and a pulse signal acquisition unit connected with the bias amplifying unit; and the eddy current retarder is also connected with the pulse signal acquisition unit and the inductor voltage reduction drive unit. The inductor voltage reduction drive type eddy current retarder control system based on the bias amplification has the advantages that a load signal of the eddy current retarder can be amplified without distortion by virtue of the pulse bias amplifying unit, and the real-time operational state of the eddy current retarder can be accurately reflected.

Description

technical field [0001] The invention relates to an eddy current retarder control system, in particular to an inductance step-down driven eddy current retarder control system based on bias amplification. Background technique [0002] Eddy current retarder is an auxiliary braking device for automobiles, commonly known as electric brake, which is mainly used in large passenger cars, urban buses and heavy trucks. The device is installed between the car drive axle and the gearbox, and realizes non-contact braking through the principle of electromagnetic induction. [0003] With the popularity of eddy current retarders and the increasing number of electrical systems on passenger cars, more and more information exchanges between eddy current retarders and other electrical systems such as ABS systems and engine control systems, while traditional electrical signals The control method leads to more and more complicated wiring harness of the eddy current retarder control system, which...
