Vehicle warning method and device and vehicle

Abstract

The invention relates to a vehicle alarm method and device and a vehicle, and relates to the field of vehicle safe driving, and the method comprises the steps: obtaining a historical wear extent from the wear extent detected by a wear sensor under the condition that the wear sensor of the vehicle detects the wear extent, obtaining a historical mileage, the historical driving mileage comprises the driving mileage accumulated before the historical moment corresponding to the historical abrasion loss of the vehicle, and the friction sensor is used for detecting the abrasion loss of a friction material of a vehicle brake. And determining a first wear rate of the friction material according to the historical driving mileage and the historical wear loss. Obtaining the current driving mileage, wherein the current driving mileage comprises the driving mileage accumulated by the vehicle before the current moment; and determining the current total wear amount of the friction material according to the first wear rate and the current driving mileage. And sending an alarm message according to the current total wear amount.

Description

technical field [0001] The present disclosure relates to the field of safe driving of vehicles, and in particular, to a vehicle warning method, device, and vehicle. Background technique [0002] With the increasing number of vehicles in the market, vehicle safety issues are getting more and more attention. Friction pads are a key component in automobile brakes. With the increase of braking times, the friction pads will be worn thinner and thinner until completely After wear, the friction plate will lose its braking effect, so the wear of the friction plate is a very important safety issue. [0003] At present, in the prior art, the alarm is triggered by the position where the friction plate reaches the mechanical alarm plate or the alarm is triggered when the electronic circuit is worn off. The above two alarm methods are to trigger the alarm after the friction plate reaches the wear limit. However, this When the two methods trigger the alarm, the wear of the friction plate...

AI Technical Summary

Problems solved by technology

[0003] At present, in the prior art, the alarm is triggered when the friction plate reaches the position of the mechanical alarm plate or the alarm is triggered when the electronic circuit is worn out. The above two alarm methods trigger the alarm after the friction plate reaches the wear limit. However, this When the alarm is triggered by the two methods, the wear of the friction plate has reached the limit. Therefore, the driving safety of the vehicle cannot be ensured by using the above alarm method.
