Detailed description of the invention
Below to each width attached drawing of description of the invention expression content and figure in label be briefly described:
Fig. 1 is the utility model Control system architecture schematic diagram.
Specific embodiment
A specific embodiment of the invention is made further detailed below against attached drawing by the description to optimum embodiment
Thin explanation.
Middle control vehicle-mounted in the prior art, after ARM9 microprocessor collects the pressing signal of finger by capacitance sensor
According to the corresponding control execution unit movement of the logic of pressing interaction, while feedback sound is provided by the way of voice unit (VU) sounding
Sound, this mode provide touch-control feedback and are easy by the sound interference in startup procedure or outside vehicle, and feedback effects are poor.
In view of the foregoing drawbacks, the control system of the vehicular touch screen of the application improves feedback by way of vibrational feedback
Effect specifically includes: including capacitance sensor, microprocessor, microprocessor detects the hand on touch screen by capacitance sensor
Refer to touching signals；The integrated pressure sensor on vehicular touch screen, pressure sensor are used to detect the finger pressure sensitivity on touch screen
Pressure sensitivity data are simultaneously transferred in microprocessor by signal, and microprocessor is connect with miniature shock module, and shock module is for driving
Touch screen provides vibrational feedback signal.Shock module realizes that vibrating motor is integrated in the touching of vehicular touch screen using vibrating motor
Touch the back side of panel.
Capacitance sensor is integrally disposed in the capacitance touching control region of touch screen front panel, and the touch-control for detecting finger is believed
Number, the touching signals of detection are sent in microprocessor, and microprocessor is realized using Embedded ARM9 microprocessor.Micro process
Device judges the operation needed to be implemented according to the capacitance signal of acquisition, detects pressure by the pressure sensor being arranged under plate in front
Force signal is successively to determine whether be improper pressing signal, in advance when pressure is excessive or too small for effective touching signals
First nominal pressure numerical value, to avoid the pressure false triggering except pressure value.Capacitance sensor pair is being calculated in microprocessor
The instruction answered and when detecting that the pressure of touch-control meets preset value, microprocessor just executes the operation that touch-control needs to be implemented at this time,
And send a signal to corresponding execution unit.Vibrating motor is sent a control signal to while sending and executing signal, so that shake
Dynamic motor issues vibration signal, provides vibrational feedback, and the vibration of vibrating motor drives the microvibration of touch screen to provide on mobile phone
Touch feedback.To facilitate user to obtain touch-control feedback in time.
The verification of boost pressure, prevents maloperation on the basis of original, and the general pressure of operation for pressing signal can be one
A normal range, if accidentally touching, pressure value meeting very little or very big reduces mistake by the verification of pressure as a result,
Triggering.In a preferred embodiment, further by the timing module that connect with microprocessor come statistical time, work as touch-control
Overlong time illustrates that there are also problems for this touch-control, it is more likely that is error touch control, microprocessor will not issue and execute letter at this time
Number, the time of general touch-control can be at one second or so, when finger touches the time greater than 1s, it is believed that touch-control is error touch control at this time, is not sent out
The control signal for needing to operate out is to executing agency.
Using a monolith touch screen, touch screen front area controls vehicle DRIVE MODE, 360 panoramas, ESC OFF, preceding
The switching of the functions such as radar, HUD, these switching switches are that virtual functions switch, while touch key-press has pressure sensitive
The design of anti-misoperation design and vibration induction, touch screen envisaged underneath pressure sensitive structure simultaneously arrange pressure sensitive chip, can
It identifies small displacement, identifies faint pressure signal, effectively promotion product false-touch prevention volatility, and the VIBRATION DESIGN below touch screen
The finger that people is felt in vibration, effectively promotion customer experience can be transmitted.It is illustrated by taking the 360 panoramas switch on touch screen as an example:
1, when user's operation pair platform touch panel opens keypress function (by taking 360 panoramas switch as an example)
Capacitance type touch-control panel detects that the capacitance signal in 360 panorama switch key regions, signal are processed into number by MCU
Signal, while user applies pressure sensitive chip generation useful signal after certain pressure, when two kinds of signals of touch-control and pressure have
When effect, MCU generates key useful signal, is then dealt into CAN bus by CAN transceiving chip, sends control letter by CAN bus
Number to full-view camera unlatching, at this time MCU control vibration device transmitting seismaesthesia to touch panel on feedback arrive user's finger,
360 panorama modules receive this signal of dissection process after CAN message, and control display screen is switched to 360 full-view image interfaces in vehicle.From
And user seat can observe vehicle-surroundings in the car.
2, when user's operation pair platform touch panel closes keypress function (for operating 360 panoramas switch)
Capacitance type touch-control panel detects that the capacitance signal in 360 panorama switch key regions, signal are processed into number by MCU
Signal, while user applies pressure sensitive chip generation useful signal after certain pressure, when two kinds of signals of touch-control and pressure have
When effect, MCU generates key useful signal, is then dealt into CAN bus by CAN transceiving chip, and MCU controls vibration device at this time
It transmits feedback in seismaesthesia to touch panel and arrives user's finger, 360 panorama modules receive this signal of dissection process, vehicle after CAN message
In control display screen from 360 full-view image changing interfaces be last interface.To which vehicle exits panorama function, panorama module is closed
It closes.
It is the operating experience that user is effectively promoted using the vibrational feedback of touch screen first, secondly by detection pressing dynamics
To realize effective anti-error triggering.Even if user has accidentally touched control panel, phase will not be triggered before not applying certain operating force
Close function.Touch screen connecting sound equipment entertains operating system, by swing, rotation that the knob that touch screen integrates is arranged in
Turn, press and dial and turns round convenient control multimedia function.
Obviously present invention specific implementation is not subject to the restrictions described above, as long as using method concept and skill of the invention
The improvement for the various unsubstantialities that art scheme carries out, it is within the scope of the present invention.
