Steering wheel horn system, DAB module and vehicle

Abstract

The invention relates to the technical field of automobile parts, in particular to a steering wheel horn system, a DAB module and a vehicle. The steering wheel horn system includes a steering wheel horn, a tactile steering wheel horn trigger, a transmission line, and an electronic control unit, wherein the tactile steering wheel horn trigger receives and measures a pressing force from a driver, and transmits a measurement result to the electronic control unit through the transmission line to determine whether to sound the steering wheel horn. By using the steering wheel horn system and the DABmodule cooperatively applied to the steering wheel horn system, the stability of the steering wheel horn can be improved, and comfortable and reliable driving feeling can be provided for drivers andpassengers. In addition, the assembly flexibility of parts, the appearance quality and the use feeling of the vehicle and the economic applicability and the use comfort of the vehicle can be improved.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a steering wheel horn system, a DAB module and a vehicle, in particular to a steering wheel horn system, a DAB module and a vehicle with stable performance and space saving. Background technique [0002] At present, with the rapid development of modern social economy and the acceleration of urbanization, automobiles have become the main means of transportation for people to travel. The car's steering wheel horn trigger is used for the horn control on the steering wheel to provide a click function.
