According to the driving device and the electric automobile, under the condition that a watchdog chip is configured, the fault monitoring function of two control chips is achieved. The driving device comprises a first control chip, a second control chip, a first driving circuit, a second driving circuit, a watchdog chip and a reset turn-off circuit. The first driving circuit generates a driving signal of the first inverter; the second driving circuit generates a driving signal of the second inverter; the first control chip and the second control chip carry out fault monitoring mutually; when the first control chip fails, the first control chip controls the reset turn-off circuit to send a first turn-off signal to the second driving circuit and sends a first reset signal to the second control chip; and when the first control chip fails, the second control chip controls the reset turn-off circuit to send a second turn-off signal to the first driving circuit and send a second reset signal to the first control chip.
一种驱动装置和电动汽车,在配置一个看门狗芯片的情况下,实现两个控制芯片的故障监控功能。驱动装置包括第一控制芯片、第二控制芯片、第一驱动电路、第二驱动电路、看门狗芯片和复位关断电路;第一驱动电路生成第一逆变器的驱动信号;第二驱动电路生成第二逆变器的驱动信号;第一控制芯片和第二控制芯片相互进行故障监控;第一控制芯片在第一控制芯片故障时,控制复位关断电路向第二驱动电路发送第一关断信号,向第二控制芯片发送第一复位信号;第二控制芯片在第一控制芯片故障时,控制复位关断电路向第一驱动电路发送第二关断信号,向第一控制芯片发送第二复位信号。
