The present application relates to the field of electric vehicles, and particularly to an electric vehicle and an electric-machinery control method therefor, an apparatus and a storage medium. The electric-machinery control method for the electric vehicle of the present application includes: detecting a relative deformation amount of a transmission system between a driving gear and a wheel end of an electric machinery; determining a first speed differential value between a first driving-gear rotational speed and a first wheel-end converted rotational speed when the relative deformation amount is a first threshold value; determining an output torque of the electric machinery according to the first speed differential value; controlling the driving gear to perform a gear-approaching operation relative to the driven gear according to the output torque.

Electric vehicle and electric-machinery control method therefor, apparatus and storage medium

An automatic shift control method, apparatus, device and storage medium. A vehicle is controlled to perform an elastic release operation in response to a drive switching request. When unloading torque of a first electric machine of the vehicle is completed, a moving component of a disengaging and engaging apparatus of the vehicle is controlled to perform a position adaptive operation. Meshing direction and separation control is performed on the moving component when a rotational speed of the moving component reaches a stable state, to cause the moving component to move in a disengaging direction to a completely disengaged position, and switch of the vehicle from a four-wheel drive power mode to a two-wheel drive mode is completed.

Automatic shift control method, apparatus, device and storage medium

An onboard refueling vapor recovery (ORVR) system includes a main canister, a spare canister, a hydrocarbon sensor, a grade rollover valve (GRV), a fill limit vent valve (FLVV) and a fuel vapor pipe. The GRV and the FLVV are disposed at top portion of the fuel tank, with sides of the GRV and the FLVV hermetically connected with the fuel tank and a gas inlet end of the fuel vapor pipe. The main canister and the spare canister hermetically connect with a gas outlet end of the fuel vapor pipe. The main canister communicates with an intake manifold. The hydrocarbon sensor is disposed in the main canister and electrically connected with a vehicle control unit. The hydrocarbon sensor detects hydrocarbon concentration in the main canister and transmits the detection result to the vehicle control unit. The present invention also provides an automobile having the ORVR system.
