Abstract

The invention relates to a gear shifting and parking braking system, a vehicle and a control method. The gear shifting and parking braking system involves an actuating mechanism, a gear shifting mechanism and a parking mechanism, wherein the gear shifting mechanism and the parking mechanism are in transmission connection with the actuating mechanism, and the actuating mechanism drives the gear shifting mechanism to rotate forwards or reversely and drives the parking mechanism to be switched between a non-braking state and a braking state; the gear shifting mechanism is provided with a first gear, a second gear and a neutral gear, the parking mechanism is in a non-braking state when the actuating mechanism drives the gear shifting mechanism to rotate forwards, and the actuating mechanism drives the parking mechanism to enter a braking state at the same time when the actuating mechanism drives the gear shifting mechanism to rotate reversely from the neutral gear. According to the gear shifting and parking braking system, the vehicle and the control method, the integration level of the gear shifting and parking braking system is improved, the layout space is saved, and meanwhile the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of vehicles. In particular, the present invention relates to a gear shift and parking brake system, a vehicle and a control method. Background technique [0002] In current electric or hybrid vehicle transmissions, the shift mechanism and the parking brake mechanism are two independent systems. The shifting mechanism is driven by a motor and controlled by an electronic control unit (ECU), while the parking brake mechanism is a mechanical structure manually controlled by the driver. This design not only increases the manufacturing cost of the transmission, but also increases the volume of the transmission, which is not conducive to a compact layout. [0003] CN 108644371 A discloses a parking shift mechanism, which directly fixes the parking push rod assembly on the shift fork, and the parking push rod assembly moves with the shift fork to realize the meshing with the parking gear Parking. In this layout,...
