Abstract

The invention discloses a vehicle terrain recognition system and method, and a vehicle. The vehicle terrain recognition system includes a tire detection unit and a signal processing unit connected with the tire detection unit. The tire detection unit is configured to detect tire state information of one or more tires, and the tire state information comprises one or more of tire temperature information, tire pressure information or tire deformation information. And the signal processing unit is configured to receive the one or more pieces of tire state information and determine topographic features of a running road surface of the vehicle according to the one or more pieces of tire state information so that a plurality of systems of the vehicle perform parameter adjustment based on the topographic features. An advanced perception function of the vehicle and overall coordination control performance of the vehicle are improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of vehicle control, in particular to a vehicle terrain recognition system, method and vehicle. Background technique [0002] The vehicle terrain recognition system refers to a series of devices used to recognize the terrain of the road surface on which the vehicle is driving. The vehicle terrain recognition system has been widely discussed because it is related to the driving safety of the vehicle. [0003] The current vehicle terrain recognition system can usually only identify and confirm the road adhesion coefficient between the tire and the road surface during vehicle driving, so that a certain system of the vehicle (such as the braking system) can be adjusted according to the road adhesion coefficient to ensure the driving of the vehicle Safety. [0004] However, since most systems of the vehicle cannot be adjusted according to the road surface adhesion coefficient during the dri...
