Description
Technical field
The utility model relates to mobile unit technical field, particularly relates to a kind of vehicle-mounted vidicon with projection alarm function.
Background technology
According to human-factor engineering structure, when vehicle is for running at high speed, the driver being positioned at rear is 1.2 to 2.0 seconds to the front truck brake differentiation time, and vehicle for running at high speed time, current vehicle emergency brake also occurs violent when subtracting acceleration/accel, can cause the braking safe Distance Shortened of front vehicle.Moreover the speed of a motor vehicle is faster, then the braking safe reaction time needed for driver must ahead of time, and the braking safe reaction distance simultaneously also can along with increase.
But the brake cresset of general vehicle only has permanent bright display format.When vehicle is in running at high speed, when front truck driver is for emergency brake, be positioned at the front vehicle drink speed of a motor vehicle suitable, instantly cannot judge that front truck is general braking state at once, or emergency brake state, cause rear car driver realize and be emergency brake action time, usually all can be not enough because of braking safe distance, cause vehicle overtaking collision event to occur, and endanger rear car driver and take the life of this car passenger.
Therefore, prior art existing defects, needs to improve.
Utility model content
The purpose of this utility model overcomes the deficiencies in the prior art, provides a kind of vehicle-mounted vidicon with projection alarm function.
The technical solution of the utility model is as follows: the utility model provides a kind of vehicle-mounted vidicon with projection alarm function, comprise: processing unit, and the sensor unit, rearview camera, vehicle-carrying display screen and the LED projection module that are electrically connected with described processing unit respectively; Described sensor unit is for obtaining car retardation situation, and when car retardation exceeds the deceleration threshold value of setting, described processing unit starts described LED projection module and carries out projection warning.
Described sensor unit comprises a weight sensor be electrically connected with described processing unit, and described weight sensor is for detecting vehicle deceleration situations.
Described sensor unit comprises an acceleration pick-up be electrically connected with described processing unit, and described acceleration pick-up is for detecting vehicle deceleration situations.
Described sensor unit also comprises the car speed sensor be electrically connected with described processing unit, and described car speed sensor is for detecting real-time vehicle running speed.
The described vehicle-mounted vidicon with projection alarm function also comprises the bus interface be electrically connected with described processing unit, and described bus interface is used for being connected with vehicle CAN bus, to obtain the real-time road speed of vehicle.
