Vehicle-mounted pressure sensing interactive system

The invention relates to the field of vehicle-mounted control systems, in particular to a vehicle-mounted pressure sensing interactive system. The vehicle-mounted pressure sensing interactive system comprises a sensor unit, a control unit and a communication unit. The sensor unit comprises at least two pressure sensors distributed at the edge of a steering wheel or a steering wheel cover. The control unit comprises an amplification circuit and a micro-processor. The amplification circuit is used for amplifying pressure signals collected by the pressure sensors. The micro-processor is used for processing the pressure signals. The communication unit is connected with the micro-processor and comprises a circuit interface and/or a wireless transmission module which is/are interconnected with a vehicle-mounted computer or an external terminal. The vehicle-mounted interaction system provided by the invention is designed to be pressure sensing-type and can be used without affecting the normal driving habit of a driver and a safety driving mode. Information from the vehicle-mounted system or a mobile phone and other intelligent terminals can be effectively processed during a driving process so that safety driving is guaranteed.
