The invention provides a connector, a motor control system comprising the connector, an electric drive assembly and a vehicle. The connector comprises a transmission piece, the middle part of the transmission piece is provided with a contraction section, and the width of the transmission piece at the contraction section is narrowed; the sensing unit and the transmission piece are fixed in a spaced mode, and the sensing unit is located at the contraction section and used for detecting the current transmitted in the transmission piece; the on-off device and the transmission part are fixed at an interval, the on-off device comprises a power generator and an on-off piston, the on-off piston is movably arranged between the power generator and the transmission part, and after the power generator is activated, the on-off piston can be pushed to move towards the contraction section and enable the transmission part to be disconnected. According to the connector, the functions of current sensing and circuit breaking are integrated, fusion of a sensor and a breaker is achieved, the purpose of reducing the size of a motor control system is achieved, and then the power density of the motor control system is improved.
