Abstract

The invention discloses a vehicle steering wheel haptic feedback system and a feedback method thereof. According to the haptic feedback system, linear vibration motors are embedded into a steering wheel, and haptic feedback is conducted through vibration of the linear vibration motors. The feedback method comprises a common feedback mode, a break-off feedback mode and an emergency feedback mode; when a vehicle auxiliary system needs to be subjected to information feedback, a feedback request is sent to a vehicle controller ECU, the vehicle controller ECU starts the different feedback modes according to the feedback request, accordingly, different control signals are generated, and the linear vibration motors embedded in the steering wheel are driven to work. According to the vehicle steering wheel haptic feedback system and the feedback method thereof, the linear vibration motors are connected with the vehicle controller ECU through signal wires, various different haptic signals can be fed back, and the man-machine interaction mode between a driver and a vehicle is enriched.

Description

technical field [0001] The invention belongs to the technical field of vehicle human-computer interaction, in particular to a vehicle steering wheel tactile feedback system and a control method thereof, and is especially suitable for vehicles equipped with on-board computers. Background technique [0002] With the development of intelligent vehicle systems, vehicles are becoming more and more intelligent, and correspondingly, more and more information can be conveyed to drivers. In the traditional driving process, drivers often obtain feedback information through vision, hearing and a small part of touch. Among them, the feedback of tactile information is often limited to the feedback of force and torque (such as pedal sensory feedback, steering wheel torque feedback, etc.). In the existing tactile information feedback technology, there are few ways of tactile information feedback, and the driver’s rich tactile sensory capabilities in the process of human-computer interacti...
