Method for prolonging hardware fault response time of new energy automobile driver by using cpld

The invention discloses a method for prolonging the hardware fault response time of a new energy automobile driver by using a cpld, relates to the technical field of new energy automobile drivers, and aims to solve the technical problem that in the prior art, the new energy automobile driver cannot carry out emergency treatment in time when encountering an emergency. According to the method for prolonging the hardware fault response time of the new energy automobile driver by using the cpld, the cpld is added to timely process hardware faults, and meanwhile, when a protection strategy is upgraded and optimized, a hardware circuit does not need to be adjusted, and only an internal program needs to be modified; the cpld is an independent device, so that when calculation fails, the cpld can be regarded as a whole, the fault rate of a hardware circuit is reduced, and the stability of the whole circuit is improved; a state machine in the cpld can make a quick response to a fault, and an internal spi slave protocol
