The invention provides an electronic gear system and method. The system comprises an electronic gear device, a gear controller, an electronic parking locking system and a vehicle control unit, wherein the vehicle control unit is connected with the gear controller and used for powering the gear controller; the gear controller is connected with the electronic gear device and used for receiving the gear signals sent by the electronic gear device and determining the types of the gear signals; the electronic parking locking system is connected with the gear controller and comprises a parking motor and a position sensor, wherein the position sensor detects the rotation state and the position of the driving shaft of a parking mechanism and determining the current state of the parking system according to the rotation state and the position. When a gear locking signal is determined to be valid or the gear controller receives a power-on demand sent by the vehicle control unit and the current state of the electronic parking system meets a preset automatic locking condition, the gear controller generates a gear instruction corresponding to the locking signal to drive the parking motor to work to achieve the locking of a vehicle driving axle.
Description
technical field [0001] The invention relates to the field of hybrid electric vehicle control, in particular to an electronic gear system and a control method. Background technique [0002] With the depletion of global oil resources and the increasing emission requirements, new energy vehicles, which are more economical and environmentally friendly than conventional vehicles, have become the design focus of major automobile manufacturers, while electric vehicles and hybrid vehicles mainly driven by electricity are gradually Become the mainstream trend of automobile development. In an electric vehicle or a hybrid electric vehicle mainly driven by electricity, the power system is usually composed of a drive motor and a reduction transmission system. Under the control of the vehicle controller, the vehicle is driven forward, backward or neutral, while the electronic gear It is a device that directly senses the user's driving intention when driving. The existing electronic gear...
