Abstract

The invention provides a haptic vibration feedback circuit, a control method and a control device. The haptic vibration feedback circuit comprises a pressure film module, a capacitive screen module, aprocessor electrically connected with the pressure film module and the capacitive screen module, and a haptic feedback module electrically connected with the processor, the pressure film module is used for detecting a pressure value generated by a pressing event of a user; the capacitive screen module is used for detecting a pressing position parameter of a pressing event of a user; the processoris used for generating a haptic vibration feedback signal based on the pressure value and the pressing position parameter; and the haptic feedback module is used for performing haptic vibration feedback by utilizing the haptic vibration feedback signal. The pressure value of the pressing event is obtained through the pressure film module; and the capacitive screen module acquires a pressing position parameter of the pressing event, the processor generates a haptic vibration feedback signal based on the pressure value and the pressing position parameter, and the haptic feedback module performshaptic vibration feedback according to the haptic vibration feedback signal, so that the key structure has a haptic vibration feedback prompt.

Description

【Technical field】 [0001] The invention relates to the technical field of force tactile feedback, in particular to a force tactile vibration feedback circuit, control method and device. 【Background technique】 [0002] In the existing automotive field, most of the functions or applications in the car are started by pressing a button event. In order to improve the user's experience with the car's functions, some car functions and corresponding buttons are usually added to the car's interior design. , in order to improve the user's experience of the multi-function in the car. [0003] At present, in the automotive field, in the design of the buttons inside the vehicle, it is usually designed to use a mechanical structure button for the user to control the functional events in the vehicle. However, the mechanical structure button does not have a tactile vibration feedback prompt, which makes it easy for the driver to distract the driver's attention during the process of pressing...
