Embodiment Construction

[0043] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0044] The present invention provides a vehicle control method, a device and an automobile, aiming at the problem that the intervention control method for vehicle slippage in the prior art has a certain hysteresis, resulting in poor driving experience.

[0045] like figure 1 As shown, one embodiment of the present invention provides a vehicle control method, including:

[0046] S11: Acquire road surface information during driving of the vehicle.

[0047] Further, obtaining the road surface information during the driving of the vehicle, including:

[0048] The road surface information is acquired through a forward-looking camera installed on the vehicle.

[0049] It should be noted that if image 3 As shown, the embodiment of the present inv...

Abstract

The present invention provides a vehicle control method, device and automobile. The control method includes: obtaining road surface information during vehicle driving; obtaining the road surface adhesion coefficient of the vehicle driving road surface according to the road surface information; , determine the driving torque corresponding to the road surface adhesion coefficient; wherein, the driving torque corresponding to different road surface adhesion coefficients is recorded in the pre-stored road surface information database; according to the driving torque corresponding to the road surface adhesion coefficient, the torque output control. The above solution realizes a function of predicting road conditions of the electric vehicle TCS, which can adaptively adjust the traction force according to the road surface information, and can self-study and improve the road surface information database.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a vehicle control method, a device and an automobile. Background technique [0002] The Traction Control System (TCS) of electric vehicles judges the vehicle slip rate in real time through the wheel speed signal, requests the vehicle controller to adjust the driving torque according to the vehicle dynamic model, controls the vehicle slip rate, and realizes the stable acceleration of the vehicle. [0003] The above control scheme has a certain hysteresis, and the control is only intervened after the vehicle slips, which will inevitably bring the driver and the occupants a sense of intrusiveness in the early stage of the intervention control, which will affect the driving experience. SUMMARY OF THE INVENTION [0004] Embodiments of the present invention provide a vehicle control method, device, and vehicle, which are used to solve the problem that the prior art intervention contr...
