Problems solved by technology
[0002] At present, with the continuous growth of car ownership, although it brings convenience to people's travel, due to the increasing types of vehicles and the functions of vehicles, there are more and more failures, which brings many safety hazards
For example: if the tire pressure is abnormal during driving, it will not only affect the service life of the wheel, but also cause the vehicle to lose control and cause an accident
Although many vehicles are currently equipped with related tire pressure monitoring equipment, these tire pressure monitoring equipment are usually costly and cumbersome to install, and are not popularized in many low-end vehicles.
In addition, the functions of these tire pressure monitoring equipment are sometimes not very stable, and there may be problems such as inaccurate tire pressure monitoring

The invention discloses a tire pressure detection method and tire pressure detection system for a vehicle, and the vehicle. The tire pressure detection method comprises the following steps of: judging whether the vehicle is in a straight running state based on a plurality of lateral acceleration speeds of the vehicle, detected within a first preset time; if the vehicle is in the straight running state, further detecting a rotation signal of a steering wheel, and recording duration time that a steering wheel is rotated in a first rotation direction when the rotation signal of the steering wheel is detected; when the duration time is greater than a second preset time, determining that the tire pressure is abnormal, and determining a tire having an abnormal tire pressure based on the first rotation direction; and generating a tire pressure abnormal alarm signal according to the tire having the abnormal tire pressure, and sending an alarm. Through the adoption of the tire pressure detection method disclosed by the invention, the tire pressure can be detected for normal or abnormal in a convenient, simple and accurate manner, and besides, no additional equipment assistance is needed, so that the tire pressure detection method is a low-cost tire pressure monitoring means and has wide applicability.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to a vehicle tire pressure detection method, system and vehicle.
