A gearshift lock for a gearbox includes a gearshift cylinder and a pawl wheel with a toothing. The gearshift lock includes a rotatably positioned pawl, and the pawl engages in the toothing of the pawl wheel in a locked position, and is disengaged from the pawl wheel in a freewheeling position. The pawl is pretensioned by a spring element in the direction of the locked position, and an engagement element is connected to the pawl. The engagement element holds the pawl in the freewheeling position by directly interacting with the gearshift cylinder against the effect of the spring element when the gearshift cylinder takes up a rotational position in a freewheeling rotational range, and the pawl can be released from the gearshift cylinder into a locked position by the engagement element when the gearshift cylinder takes up a rotational position in a locked rotational range.

A vehicle park lock control method is presented with range positions including a P-range position and an N-range position in each of which a driving force is prevented from being transmitted to a driving wheel of a vehicle. A park lock mechanism is activated when in the P-range position. An operator is allowed to select whether or not to cause the park lock mechanism to be activated in response to key-off operation when in the N-range position. In response to continuous shifting of a range selector to one or more specific ones of the range positions, the park lock mechanism is prevented from being activated in response to key-off operation when in the N-range position.

The invention relates to a gearbox (40) having a park lock (42) which is integrated in a gearbox housing (60) of the gearbox (40). Said park lock comprises a transfer device (48), a detent (50), and a park lock gear (52). Outside the gearbox housing (60) there is an electromechanical actuator (44), which is centred on an interface to the transfer device (48) on the gearbox housing (48) and is sealed off from the gearbox housing (60) there.

A shift device includes: a shift switching member including valley portions provided so as to correspond to shift positions; a positioning member causing the shift position to be established while being fitted in any of the valley portions of the shift switching member; a motor driving the shift switching member and including a rotor and a stator; a driving force transmission mechanism transmitting a driving force from the motor to the shift switching member; and a rotor rotation angle sensor and an output shaft rotation angle sensor detecting rotation angles of the rotor and the shift switching member. The shift device corrects a deviation from a center of a preset backlash when a backlash width included in the driving force transmission mechanism detected based on output values of the output shaft rotation angle sensor and the rotor rotation angle sensor is a value or more during a shift switching operation.

A drive unit (100) is provided with a first electric machine (110), a second electric machine (120), a first shaft (130) and an output shaft (140). A rotor (111) of the first electric machine (110) is rotationally fixed to the first shaft (130), and a rotor (121) of the second electric machine (120) is rotationally fixed to the output shaft (140). The drive unit (100) also includes a separating clutch (150) and a connection element (230) for the rotationally fixed connecting of an internal combustion engine, and a first gear ratio step (142) is arranged between the connection element (230) and the shafts (130, 140) with a gear ration i<1. The drive unit (100) has an electro-mechanical parking lock unit (1) with which a rotational movement of the output of the first gear ratio step (142) can be blocked.
