The invention discloses a protection circuit, a protection control method of an electric drive system, the electric drive system and a vehicle. The protection circuit comprises a sampling module and a control module. The sampling module is used for obtaining multiple sampling signals of the electric drive system, and the control module is connected with the sampling module and used for executing protection measures on the electric drive system when at least two sampling signals in the multiple sampling signals of the electric drive system are abnormal. The protection circuit can collect various signals for comprehensive processing, all signal processing is carried out in the control module, an external signal processing circuit does not need to be added, the overall structure does not need to be optimized, whether the electric drive system is protected or not is comprehensively decided by considering various different types of sampling signals, the safety and reliability are improved, and the cost is reduced. And misjudgment caused by abnormal sampling or damage of the sampling module is avoided.
