Embodiment Construction
[0051] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.
[0052] An embodiment of the present disclosure provides a vehicle driving mode switching method, which can be applied to an electric commercial vehicle. The electric commercial vehicle includes a vehicle controller, which is mainly used for the coordination and control of the vehicle power system, and performs torque and control from the perspective of the vehicle. Speed control can effectively improve driver experience and reduce energy consumption. The vehicle controller can be applied in a vehicle driving mode switching system, and the vehicle driving mode includes a single-axle driving mode and a multi-axle driving mode (such as a double-axle driving mo...

The present disclosure relates to a vehicle driving mode switching method, device and storage medium, an electric commercial vehicle, and relates to the field of vehicle control. The vehicle driving mode switching method includes: obtaining the acceleration, speed and road gradient of the vehicle when the vehicle is currently driving; Parameters to determine the maximum road surface slope that can drive the vehicle in the single-axle drive mode; compare the road surface slope when the vehicle is currently driving with the maximum road surface slope that can drive the vehicle in the single-bridge drive mode, and generate a first comparison result; When the first comparison result satisfies the set condition, the driving mode of the vehicle is switched, so that in an uphill scene, the driving mode switching is accurately performed according to the actual driving scene of the vehicle, and the normal driving of the vehicle is guaranteed. Reduced energy loss when driving.
Description
technical field [0001] The present disclosure relates to the field of vehicle control, in particular, to a vehicle driving mode switching method, device, storage medium, and electric commercial vehicle. Background technique [0002] A multi-drive system refers to a vehicle drive system composed of two or more single drive devices that can operate simultaneously. The driving power of the vehicle is provided by a single drive device alone or jointly by multiple drive devices according to the actual vehicle driving state. [0003] The multi-drive system in the traditional technology can select the vehicle driving mode according to the operating conditions of the vehicle. For example, when the vehicle is in the starting condition, it can start smoothly with one axle and two wheels and start quickly with two axles and four wheels; when the vehicle is in the cruising condition , it can realize single-axle front-wheel drive, single-axle rear-wheel drive or dual-axle four-wheel driv...
