The invention discloses an axle power generation system and a vehicle, the axle power generation system comprises an excitation driver, a generator, a main rectifier, a detection unit and a processor which are connected in sequence, the excitation driver is used for generating excitation current, so that the generator generates induced electromotive force under the action of the excitation current and outputs alternating current to the outside; the main rectifier is used for rectifying alternating current into first direct current; the detection unit is used for detecting the voltage of the first direct current; the processor is used for outputting a first current instruction to the excitation driver when the voltage of the first direct current is greater than a preset voltage so as to reduce the excitation current of the excitation driver, and outputting a second current instruction to the excitation driver when the voltage of the first direct current is less than the preset voltage so as to increase the excitation current of the excitation driver; therefore, voltage stabilization control on the output voltage of the generator is realized. According to the invention, direct-current voltage-stabilizing output can be realized, a load loop can be detected, and overcurrent and overvoltage conditions of a load can be prevented.

    本发明公开了一种车轴发电系统和车辆,该车轴发电系统包括依次连接的励磁驱动器、发电机、主整流器、检测单元和处理器,其中,励磁驱动器用于产生励磁电流,以便发电机在励磁电流作用下产生感应电动势,并对外输出交流电;主整流器用于将交流电整流为第一直流电;检测单元用于检测第一直流电的电压;处理器用于在第一直流电的电压大于预设电压时,输出第一电流指令至励磁驱动器,以使励磁驱动器降低励磁电流,以及在第一直流电的电压小于预设电压时,输出第二电流指令至励磁驱动器,以使励磁驱动器增加励磁电流,以便实现对发电机输出电压的稳压控制。本发明能够实现直流电稳压输出,并能够对负载回路进行检测,防止负载出现过流过压状况。
