Abstract
The present invention discloses a kind of adaptive taillight control system, belongs to taillight control field.It includes postposition image processor, BCM modules, rear light controller and taillight module, and postposition image processor is connect with rear light controller by CAN/LIN buses, and BCM modules are connect with postposition image processor by CAN bus, for obtaining fog lamp switch signal.The present invention adjusts taillight brightness in real time according to front vehicle at a distance from this vehicle, avoid because taillight is excessively bright rear car driver is caused to dazzle the eyes while, be not reduced the warning distance to rear car.Further, under the severe weather conditions such as misty rain day, when by judging that fog lamp switch is opened, the present invention is in misty rain day mode, will improve taillight brightness under the brightness degree of non-misty rain day mode, maintains the adaption brightness regulatory function of taillight.Technical solution through the invention substantially increases the safety of driver's nighttime driving.
Description
Technical field
The invention belongs to taillight control field, especially a kind of adaptive taillight control system.
Background technology
When nighttime driving vehicle, rear-end collision caused by due to driver's carelessness takes place frequently.In the prior art, have
The technical solution of taillight brightness is adjusted according to speed, or taillight brightness is adjusted according to vehicle running state.Such as application No. is
201320615091.0 patent, discloses a kind of taillight control system and automobile, the patent solve night automobile and waiting for
When red light, due to dazzling the eyes problem caused by the brighter driver rear car of taillight.Technical solution described in the patent：By obtaining
Vehicle speed information is taken to judge whether vehicle is stationary state, when a vehicle is at rest, taillight brightness is in relatively low
Rank；Conversely, when vehicle is in transport condition, taillight is restored to normal brightness rank.But the technical solution is in the presence of scarce
It falls into, i.e., when vehicle is in relatively low level intensity, if front vehicle if drive at a distance, is virtually reduced to rear car
Warning distance.Especially in the case of this visibility in misty rain day is lower, such case seems especially dangerous.
Invention content
In order to solve the above technical problems, the present invention provides a kind of adaptive taillight control system.
To achieve the above object, the present invention uses following technical proposals：
A kind of adaptive taillight control system, the control system include postposition image processor, rear light controller and taillight
Module, postposition image processor are connect with rear light controller by CAN/LIN buses, and rear light controller is connect with taillight module；
Postposition image processor identifies front vehicle in real time, and judges that front vehicle is at a distance from this vehicle and current desired
Brightness degree, rear light controller control taillight brightness in taillight module by adjusting PWM wave in real time.
Further, postposition image processor is installed on vehicle rear seat windscreen；
Postposition image processor includes camera module and signal processor, and camera module acquires front vehicle in real time
Image information is sent to signal processor, and signal processor obtains front vehicle range information from image information, and judges
Front vehicle, further according to preset distance and brightness relationship, obtains current desired brightness degree and with control at a distance from this vehicle
The form of order is sent to rear light controller, rear light controller by adjusting PWM wave come adjust in taillight module taillight brightness to
Corresponding bright.
Further, control system further includes BCM modules, and BCM modules are connected with postposition image processor by CAN bus
It connects；
BCM modules obtain fog lamp switch signal and are sent to postposition image processor, and postposition image processor is according to fog lamp
Switching signal judges to be presently in pattern, and taillight control will be sent in the form of control command in misty rain day mode
Taillight brightness in taillight module is turned up by adjusting PWM wave under current brightness level in device, rear light controller.
Advantageous effect：
The present invention adjusts taillight brightness in real time according to front vehicle at a distance from this vehicle, is avoiding because taillight is excessively bright and right
While rear car driver causes to dazzle the eyes, it is not reduced the warning distance to rear car.Further, when severe in misty rain day etc.
Under weather condition, when by judging that fog lamp switch is opened, the present invention is in misty rain day mode, will be in the bright of non-misty rain day mode
Taillight brightness is improved under degree grade, maintains the adaption brightness regulatory function of taillight.Technical solution through the invention,
Substantially increase the safety of driver's nighttime driving.
