The invention discloses a controller of a permanent magnetic synchronous motor for an electric vehicle and a vehicle-mounted system. The controller comprises a current collecting device, a processor, a driving circuit, a power device, a switching value control device and a switch power source device. The current collecting device is used for collecting and processing the alternating current output by the motor. The processor is connected with the current collecting device and used for controlling the alternating current through a comparison result obtained after comparison processing is conducted through a reference parameter to generate driving signals. The driving circuit is connected with the processor and used for receiving and processing the driving signal to output control signals. The power device is connected with the driving circuit and used for receiving the control signals to control the on-off of an MOS power pipe in the power device. The switching value control device is connected with the power device through a closing switch and a braking switch and used for controlling the starting and braking of the motor. The switch power source device is connected with the driving circuit and used for providing electric energy. By means of the controller, the permanent magnetic synchronous motor controller high in precision and large in range can be achieved.
