Self-excited retarder generating device stability control system

Abstract

The invention discloses a self-excited retarder generating device stability control system. The self-excited retarder generating device stability control system comprises a self-excited retarder; the voltage signals of the output end of a self-excited retarder generating device are connected with one input end of a voltage comparator, and the output end of the voltage comparator is connected with a control unit; the voltage signals of the output end of the self-excited retarder generating device are connected with a relay, which is connected with the control unit; the voltage signals of the input end of the self-excited retarder generating device are connected with the output end of the self-excited retarder generating device through a transformer; the control unit is connected with a driving circuit, and the driving circuit drives the change of the number of turns of the primary coil of the transformer. The self-excited retarder generating device stability control system adjusts the change of the number of turns of the primary coil of the transformer through the driving circuit to change the voltage of the output end of the self-excited retarder generating device and further to maintain the voltage within a certain range, thereby improving the stability of the output voltage of the self-excited retarder, improving the utilization rate of a self-generating device, achieving large retarding energy and further enhancing the vehicle driving safety.

Description

technical field [0001] The invention relates to the field of vehicle braking, in particular to a stability control system and a control method of a self-excited retarder power generation device. Background technique [0002] On September 1, 2012, the GB7258 standard "dangerous goods transport vehicles and trucks with a total mass greater than 12 tons should be equipped with retarders or other auxiliary braking devices" was implemented on September 1, 2012. It means that the auxiliary braking device will soon become the standard equipment for heavy trucks over 12 tons. More and more auxiliary braking systems are installed on medium and heavy trucks and other passenger vehicles, such as eddy current retarders, hydraulic retarders, etc. However, these retarders need to consume external energy, resulting in energy loss. The self-excited retarder has a self-generating function and does not require an external power supply. However, the output voltage of the self-excited retarder...

However, these retarders need to consume external energy, resulting in energy loss. The self-excited retarder has a self-generating function and does not require an external power supply. However, the output voltage of the self-excited retarder power generation device varies greatly, which is likely to cause output voltage stability. Poor, affecting the safety of the vehicle
