A transmission, such as a transmission for a vehicle, a driveline including the transmission, and a method of performing a gear shift using the transmission. The transmission comprises a first transmission shaft, a first gear disposed on the first transmission shaft, a first wet clutch, and a first synchronizer. The first wet clutch and the first synchronizer are configured to selectively drivingly engage the first gear with the first transmission shaft and are connectable in series between the first gear and the first transmission shaft, such that the first gear is drivingly engaged with the first transmission shaft only when both the first wet clutch and the first synchronizer are engaged, and such that the first gear is drivingly disengaged from the first transmission shaft when either one or both of the first wet clutch and the first synchronizer is/are disengaged.

Related are a method and an apparatus for protecting a clutch in a vehicle driving process. The method comprises: acquiring a current oil temperature of a space where the clutch is located and judging whether the current oil temperature is within a set temperature interval or not; in a case where the current oil temperature is within the set temperature interval, detecting whether a current wheel speed difference between front shaft and rear shaft reaches to a set wheel speed difference threshold or not; and in a case where the current wheel speed difference between the front shaft and rear shaft reaches to the set wheel speed difference threshold, triggering a first protective mode that is preset to protect the clutch; and in a case where the current oil temperature is higher than the set temperature interval, triggering a second protective mode that is preset to protect the clutch.

A method for controlling a motor of a vehicle and the vehicle are presented. The vehicle includes the motor, a control unit, a continuously variable transmission (CVT) comprising a primary pulley, a secondary pulley, and a belt looped around the primary and secondary pulleys, the belt transmitting torque between the primary and secondary pulleys and at least one ground engaging member operatively connected to the secondary pulley. The method is performed at least in part by the control unit. The method comprises determining a CVT ratio of the CVT; determining a current power output of the motor; determining a power boundary based in part on the CVT ratio; determining, when the current power output of the motor is greater than the power boundary, a torque setting based at least in part on the CVT ratio; and controlling the motor to operate under conditions corresponding to the torque setting.
