fig. 1 is a flowchart of a lighting control method for an emergency brake of a vehicle according to a first embodiment of the present invention;
fig. 2 is a block diagram showing the structure of a lighting control system for an emergency brake of an automobile according to a second embodiment of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, a lighting control method for an emergency brake of an automobile according to a first embodiment of the present invention includes steps S101 to S102.
S101, when the electronic vehicle body stabilizing system monitors that the vehicle speed is greater than or equal to a vehicle speed threshold value when the vehicle runs and the deceleration of the vehicle is greater than or equal to a deceleration threshold value, the electronic vehicle body stabilizing system outputs a brake response CAN signal in an activated state to a vehicle body controller.
Specifically, the running state of the vehicle can be sensed through a four-wheel speed sensor, and the state of the vehicle in the running process is sent to an Electronic Stability Program (ESP) of the vehicle body in real time.
After the ESP receives wheel speed signals sent by wheel speed sensors of four wheels in real time, internal software decides and judges whether the running state of the vehicle needs to activate an emergency braking state or not, and judges whether the state of sending a braking response CAN signal ABS _ HAZActive is an activated state or an inactivated state.
In particular, the vehicle speed threshold is, for example, 50km/h, and the deceleration threshold is, for example, -6m/s2It should be noted that the deceleration of the vehicle mainly refers to the longitudinal deceleration, and the deceleration of the vehicle being greater than or equal to the deceleration threshold refers to a comparison of absolute values, not including direction, e.g. the actually measured deceleration is-10 m/s2Then the measured deceleration is greater than the deceleration threshold.
In addition, the vehicle speed threshold and the deceleration threshold are not fixed values, and are specifically based on ESP calibration data.
And S102, after receiving the brake response CAN signal in the activated state, the automobile body controller controls the rear brake lamp and the high-order brake lamp to flash at a preset frequency through a hard wire so as to enter an emergency brake flashing mode.
For example, in the emergency stop flashing mode, the rear stop lamp and the high stop lamp are flashed at a frequency of three times per second.
Further, as a specific example, the method further includes:
when the electronic vehicle body stabilization system monitors that the vehicle speed is less than a vehicle speed threshold value or the deceleration of the vehicle is less than a deceleration threshold value when the vehicle runs, the electronic vehicle body stabilization system outputs a brake response CAN signal in an inactivated state to a vehicle Body Controller (BCM);
and after receiving the brake response CAN signal in the inactivated state, the automobile body controller controls the rear brake lamp and the high-order brake lamp to exit the emergency brake flashing mode through the hard wire.
In this embodiment, after the BCM receives the brake response CAN signal ABS _ hazctive from the ESP, the software policy inside the BCM determines whether to enter or exit the emergency brake blinking mode, and specifically determines whether to enter the emergency brake blinking mode according to the value of the received brake response CAN signal.
And when the value of the brake response CAN signal ABS _ HAZActive received by the automobile body controller is 0, the automobile body controller does not enter or exit the emergency brake flashing mode.
And when the value of the brake response CAN signal ABS _ HAZActive received by the automobile body controller is 1, maintaining or entering an emergency brake flashing mode.
Specifically, in the emergency brake flashing mode, the flashing counting time of the rear brake lamp and the high-order brake lamp is longer than the time of the brake response CAN signal sent to the vehicle body controller by the minimum integer plus 1 second, the time shorter than 1 second is calculated according to 1 second, and the flashing frequency of the emergency brake lamp CAN be set according to the actual situation.
According to the lighting control method for the emergency brake of the automobile, the entering and exiting of the emergency brake flashing mode are controlled by the automobile body electronic stabilizing system and the automobile body controller, and can be realized through internal programs of the automobile body electronic stabilizing system and the automobile body controller, so that the method is not easily interfered by the outside and has high reliability; in addition, the on and off of the emergency brake flashing mode are controlled by monitoring the vehicle running state by the vehicle body electronic stabilizing system, and the actual measurement shows that the error of the flashing time of the emergency brake lamp can be reduced to 0.5 second, so that the deviation and the time delay can be effectively reduced.
Referring to fig. 2, based on the same inventive concept, a lighting control system for emergency braking of an automobile according to a second embodiment of the present invention includes an electronic vehicle body stabilizing system and a vehicle body controller;
when the electronic vehicle body stabilizing system monitors that the vehicle speed is greater than or equal to a vehicle speed threshold value when the vehicle runs and the deceleration of the vehicle is greater than or equal to a deceleration threshold value, the electronic vehicle body stabilizing system is used for outputting a brake response CAN signal in an activated state to a vehicle body controller;
and the automobile body controller is used for controlling the rear brake lamp and the high-order brake lamp to flash at a preset frequency through a hard wire after receiving the brake response CAN signal in the activated state so as to enter an emergency brake flashing mode.
In the embodiment, when the electronic vehicle body stabilization system monitors that the vehicle speed is less than the vehicle speed threshold value or the deceleration of the vehicle is less than the deceleration threshold value when the electronic vehicle body stabilization system monitors that the vehicle runs, the electronic vehicle body stabilization system is used for outputting a brake response CAN signal in an inactivated state to the vehicle body controller;
and the automobile body controller is used for controlling the rear brake lamp and the high-order brake lamp to exit the emergency brake flashing mode through a hard wire after receiving the brake response CAN signal in the inactivated state.
In this embodiment, the vehicle body controller is configured to determine whether to enter an emergency braking blinking mode according to a value of the received braking response CAN signal.
In this embodiment, when the value of the brake response CAN signal received by the vehicle body controller is 0, the emergency brake blinking mode is not entered or exited.
And when the value of the brake response CAN signal received by the automobile body controller is 1, maintaining or entering an emergency brake flashing mode.
In this embodiment, in the emergency braking blinking mode, the blinking counting time of the rear stop lamp and the high-mount stop lamp is longer than the time of the minimum integer +1 second of the time for the brake response CAN signal to be sent to the body controller.
According to the lighting control system for the emergency brake of the automobile, the entering and exiting of the emergency brake flashing mode are controlled by the automobile body electronic stabilizing system and the automobile body controller, and can be realized through internal programs of the automobile body electronic stabilizing system and the automobile body controller, so that the system is not easily interfered by the outside and has high reliability; in addition, the on and off of the emergency brake flashing mode are controlled by monitoring the vehicle running state by the vehicle body electronic stabilizing system, and the actual measurement shows that the error of the flashing time of the emergency brake lamp can be reduced to 0.5 second, so that the deviation and the time delay can be effectively reduced.
