Detailed Description
Example 1
In an exemplary embodiment of the present invention, as shown in fig. 1-2, a brake lamp failure compensation control method is provided.
The control failure of the tail lamp generally occurs on a vehicle which is not maintained for a long time, after the brake lamp fails, other tail lamps can have the problems of insufficient brightness, untimely lighting and the like, so that the compensation light adopted by the brake lamp failure has poor reminding effect, and the requirement of accurately sending out a brake reminding signal is difficult to meet.
Based on this, this embodiment provides a brake light failure compensation control method, when detecting brake light failure, regards the illumination of other tail lamps as the compensation of brake light, and according to the ambient brightness condition and the speed information when driving, adopts appropriate tail lamp type to send the braking warning signal, improves the braking signal warning effect when brake light fails, reduces the potential safety hazard.
The following describes a brake lamp failure compensation control method in detail with reference to the accompanying drawings.
When the vehicle is unlocked or in the running process of the vehicle, the vehicle body controller detects the brake lamp through the internal circuit, if the brake lamp and the circuit thereof are damaged to cause that the brake lamp cannot be normally lightened, the brake lamp is in a failure state, and compensation control is carried out on working conditions when the brake is applied in a mode of lightening other taillights.
Referring to fig. 1, the brake lamp failure compensation method includes:
detecting whether the brake lamp fails based on the brake lamp lighting signal;
if the tail lamp is not invalid, the brake lamp is normally lightened;
if the tail lamp fails, acquiring the environment brightness information and the vehicle speed information when a brake lamp lighting signal is sent out;
if the ambient brightness is smaller than the brightness threshold value, the rear fog lamp is lightened to send out a braking reminding signal; if the ambient brightness is greater than or equal to the brightness threshold, the reversing light is lightened to send out a braking reminding signal;
if the vehicle speed is greater than or equal to the vehicle speed threshold value, the left and right steering lamps flash to send out a reminding signal; if the vehicle speed is less than the vehicle speed threshold, the left and right turn lamps are not turned on.
The status of the brake lamp is detected by a Body Controller (BCM) to judge whether the brake lamp fails. After the brake lamp is lightened, the vehicle body controller judges whether the brake lamp has a problem or not by detecting the current of the left and right rear brake lamp loops, if the brake lamp has a problem, such as a short circuit of a brake lamp circuit and a circuit, the vehicle body controller detects that the current value of the brake lamp loop exceeds a set range value and judges that the brake lamp fails, the vehicle body controller stops outputting, sends brake lamp failure information to the combination instrument through a CAN signal, and lights a lamp failure indicator lamp on an instrument desk to prompt a driver to check the brake loop.
The brake lamp lighting signal is sent out when the vehicle is unlocked, the front car lamp and the back car lamp of the vehicle are both lighted to prompt the vehicle to unlock, the vehicle body controller controls the marker lamp to be turned off after a certain period of time, and then the brake lamp lighting signal is sent out; the vehicle body controller detects the state of the brake lamp and judges whether the brake lamp fails or not.
The brake lamp electric quantity signal can be sent out when braking in the running process of the vehicle, when a brake pedal is pressed down, a brake switch is closed, a brake pressure sensor is triggered, a vehicle body controller sends out a brake lamp lighting signal, and meanwhile the state of the brake lamp is detected to judge whether the brake lamp is invalid or not.
As shown in fig. 2, the vehicle body controller detects the state of the brake lamp, two voltage comparators A1 and A2 are used for operation, reference voltages obtained by dividing voltages of R3, R4, R5 and R6 are applied to the inverting input ends of A1 and A2, and detection signals are applied to the non-inverting input ends.
When the brake switch is closed, the left and right rear brake lamps form a direct current loop through VD1 and VD2 at the moment, and the left and right rear brake lamps are lightened. And meanwhile, the MCU receives the brake switch signal, judges that the brake switch is closed, and judges the current information of the A1/A2 loop to determine the condition of the brake lamp.
When the left brake light and the right brake light are not damaged:
the resistance of the brake lamp is very small, the resistance of R1 and R2 is very large, the detection signal is smaller than the reference voltage at the moment, the output of A1 and A2 is low level, and OUT1 and OUT2 are not output, so that the brake lamp is normal.
When the left brake lamp is damaged:
the detection signal is larger than the reference voltage, A1 outputs high level, OUT1 is high level, MCU receives the signal and sends CAN information of damage of the left rear brake lamp to CAN.
When the right brake light is damaged:
OUT2 is high level, and the MCU receives the signal and sends CAN information of damage to the right rear brake lamp to the CAN.
When the left brake lamp and the right brake lamp are damaged:
OUT1/OUT2 is high level simultaneously, and the MCU receives signals and sends CAN information of damage of the two brake lamps to the CAN.
If judging that the brake lamp fails, acquiring environment brightness information and vehicle speed information, acquiring the environment brightness information to select other proper types of rear taillights for lighting, and when the environment brightness is relatively high, indicating that the vehicle running environment is good in visual field, and adopting a reversing lamp with relatively high brightness to send out a reminding signal; when the ambient brightness is relatively low, the vehicle running environment is relatively poor in visual field, a rear fog lamp with high light penetration capacity is adopted to send out a reminding signal, and a proper rear tail lamp is selected to be lightened according to different visual field conditions so as to realize reminding.
Acquiring vehicle speed information to judge whether the vehicle is in a higher vehicle speed state, wherein the vehicle is easy to control when the vehicle is at a lower vehicle speed, and a driver of a rear vehicle needs a more obvious reminding signal when the vehicle is at a higher vehicle speed; therefore, when the vehicle speed is relatively high, the left and right steering lamps flash to send out a reminding signal while the reversing lamp or the rear fog lamp is turned on; the left and right turn lamps are not turned on when the vehicle speed is relatively low.
In this embodiment, an ambient light sensor is used to measure ambient brightness, and a brightness threshold may be set to be a common automatic headlight trigger value of 1000lux, where when the ambient light sensor measures that the ambient brightness is greater than or equal to 1000lux, such as daytime running, it is determined that the field of view of the running environment of the vehicle is good, and a backup lamp is turned on to serve as compensation for a failure brake lamp, so as to send out a brake reminding signal; when the ambient light level is less than 1000lux, such as in the evening, at night or in overcast weather, it is determined that the field of view of the vehicle running environment is poor.
Acquiring vehicle speed information from a vehicle ECU, wherein the vehicle speed information comprises vehicle speed data, a vehicle body controller compares the vehicle speed data with a set vehicle speed threshold value, the vehicle speed threshold value can be set to be 20km/h, when a brake lamp lighting signal is sent out, if the real-time speed is greater than or equal to 20km/h, the vehicle speed is determined to be higher, a warning mode is required to be added, and the left and right steering lamps are controlled to flash; if the real-time speed is less than 20km, the vehicle speed is low, the vehicle is easy to control, an additional warning mode is not needed, and the left and right steering lamps are not turned on.
The brake lamp failure compensation control method will be described separately by taking an example of a good field of view of the daytime running vehicle running environment and a poor field of view of the nighttime running vehicle running environment.
As shown in fig. 1, during daytime driving:
after the brake switch is closed, the brake pressure sensor is triggered, and the vehicle body controller receives a brake signal;
after the vehicle starts to brake, the brake pressure sensor sends a signal to the vehicle body controller, and the vehicle body controller judges that the vehicle speed is reduced through the vehicle speed signal, and confirms that the vehicle is braked;
meanwhile, if the vehicle body controller detects that the left/right rear brake lamp is damaged and the position lamp is not in a connected state, the vehicle body controller replaces the brake lamp function by lighting the reversing lamp, and meanwhile, the brake lamp fault information is sent to the instrument;
and if the speed of the automobile is more than or equal to 20km/h at the moment, the left steering lamp and the right steering lamp are controlled to flash at the same time, and the front automobile of the automobile is reminded of the fault of the brake lamp so as to remind the rear automobile of paying attention.
As shown in fig. 1, during night driving:
after the brake switch is closed, the brake pressure sensor is triggered, and the vehicle body controller receives a brake signal;
after the vehicle starts to brake, the brake pressure sensor sends a signal to the vehicle body controller, and the vehicle body controller judges that the vehicle speed is reduced through the vehicle speed signal, and confirms that the vehicle is braked;
meanwhile, if the vehicle body controller detects that the left/right rear brake lamp is damaged and the position lamp is not in a connected state, the vehicle body controller replaces a brake lamp function by turning on the rear fog lamp, and meanwhile, brake lamp fault information is sent to the instrument;
and if the speed of the automobile is more than or equal to 20km/h at the moment, the left steering lamp and the right steering lamp are controlled to flash at the same time, and the front automobile of the automobile is reminded of the fault of the brake lamp so as to remind the rear automobile of paying attention.
