The following describes a vehicle turning auxiliary lighting control method, a system and a vehicle according to an embodiment of the invention with reference to the accompanying drawings.
FIG. 1 is a flow chart of a vehicle turning assist lighting control method according to one embodiment of the present invention. As shown in fig. 1, the vehicle turning assist lighting control method includes the steps of:
step S1: acquiring vehicle operation information, wherein the vehicle operation information at least comprises: the system comprises a steering deflector rod steering command, a vehicle speed, a steering wheel corner and a steering sensor calibration state.
Step S2: and outputting turning auxiliary lighting on or off requests according to the vehicle running information.
In one embodiment of the present invention, as shown in fig. 2, outputting a turn assist lighting turn-on request according to vehicle operation information includes: when a steering command of the steering deflector rod is detected, if the vehicle speed is effective, the vehicle speed is less than a first preset vehicle speed, the steering wheel angle is effective, the calibration state of the steering sensor is normal, and the steering wheel angle is greater than a first preset angle, a turning auxiliary lighting starting request is output.
In another embodiment of the present invention, as shown in fig. 3, outputting a turn assist lighting turn-on request according to vehicle operation information further includes: when a steering command of the steering deflector rod is not detected, if the vehicle speed is effective, the vehicle speed is less than a second preset vehicle speed, the turning angle of the steering wheel is effective, the calibration state of the steering sensor is normal, and the turning angle of the steering wheel is greater than a second preset angle, a turning auxiliary lighting starting request is output, wherein the second preset vehicle speed is greater than the first preset vehicle speed, and the second preset angle is greater than the first preset angle.
Specifically, when the turning auxiliary lighting is automatically turned on, the turning command of the steering lever is judged first, and corresponding function judgment is carried out according to whether the turning command of the steering lever exists or not (namely whether the driver operates the steering lever or not). When the logic judgment is carried out, the steering command of the steering deflector rod exists and the steering command of the steering deflector rod does not exist, and the set vehicle speed and the set steering wheel angle threshold are different. Specifically, when a steering command of a steering lever exists (namely, a driver operates the steering lever), the corresponding set vehicle speed is a first preset vehicle speed, and the corresponding steering wheel angle threshold is a first preset angle; when the steering command of the steering lever does not exist (namely the driver does not operate the steering lever), the corresponding set vehicle speed is a second preset vehicle speed, and the corresponding steering wheel angle threshold value is a second preset angle. And the second preset vehicle speed is greater than the first preset vehicle speed, and the second preset angle is greater than the first preset angle.
In fig. 2 and 3, the validity of the vehicle speed is a determination result of whether the collected signal of the vehicle speed is valid, and if the value is true, the vehicle speed signal is proved to be valid; the first preset vehicle speed/the second preset vehicle speed is the highest vehicle speed value of turning auxiliary lighting starting, and if the vehicle speed is smaller than the highest vehicle speed value, a turning auxiliary lighting starting request is sent; the steering wheel angle validity is a judgment result of whether the collected signal of the steering wheel angle is valid or not, and if the value is true, the steering wheel angle validity is proved; the calibration state of the steering sensor is a feedback result of calibrating the steering wheel angle signal, and if the value is true, the calibration of the steering wheel angle sensor is proved to be successful; the first preset angle/the second preset angle is the minimum steering angle for starting the turning auxiliary lighting, and if the first preset angle/the second preset angle is larger than the minimum steering angle, a turning auxiliary lighting starting request is sent.
In one embodiment of the present invention, as shown in fig. 4, outputting a turn assist lighting turn-off request according to vehicle operation information includes: when a steering command of a steering deflector rod is detected, if the vehicle speed is invalid, or the vehicle speed is greater than a third preset vehicle speed, or the steering wheel angle is invalid, or the calibration state of a steering sensor is abnormal, or the steering wheel angle is smaller than a third preset angle, a turning auxiliary lighting closing request is output, wherein the third preset vehicle speed is greater than the first preset vehicle speed, and the third preset angle is smaller than the first preset angle.
In one embodiment of the present invention, as shown in fig. 5, outputting a turn assist lighting turn-off request according to vehicle operation information further includes: when the steering command of the steering deflector rod is not detected, if the vehicle speed is invalid, or the vehicle speed is greater than a fourth preset vehicle speed, or the steering wheel angle is invalid, or the calibration state of the steering sensor is abnormal, or the steering wheel angle is smaller than a fourth preset angle, a turning auxiliary lighting closing request is output, wherein the fourth preset vehicle speed is greater than a second preset vehicle speed, and the fourth preset angle is smaller than the second preset angle.
Specifically, when the turning auxiliary lighting automatic turn-off judgment is performed, the steering lever steering command is judged firstly, and corresponding function judgment is performed according to whether the steering lever steering command exists or not (namely whether the driver operates the steering lever or not). When the logic judgment is carried out, the steering command of the steering deflector rod exists and the steering command of the steering deflector rod does not exist, and the set vehicle speed and the set steering wheel angle threshold are different. Specifically, when a steering command of the steering lever exists (namely, a driver operates the steering lever), the corresponding set vehicle speed is a third preset vehicle speed, and the corresponding steering wheel angle threshold is a third preset angle; when the steering command of the steering lever does not exist (namely the driver does not operate the steering lever), the corresponding set vehicle speed is the fourth preset vehicle speed, and the corresponding steering wheel angle threshold value is the fourth preset angle. And the fourth preset vehicle speed is greater than the second preset vehicle speed, and the fourth preset angle is smaller than the second preset angle.
In fig. 4 and 5, the validity of the vehicle speed is a result of determining whether the collected signal of the vehicle speed is valid, and if the value is true, the vehicle speed signal is proved to be valid, otherwise, the vehicle speed signal is invalid; the third preset vehicle speed/the fourth preset vehicle speed is the lowest vehicle speed value of turning auxiliary lighting, and if the vehicle speed is larger than the lowest vehicle speed value, a turning auxiliary lighting turning-off request is sent; the steering wheel angle validity is a judgment result of whether the collected signal of the steering wheel angle is valid or not, if the value is true, the steering wheel angle validity is proved, otherwise, the steering wheel angle is invalid; the calibration state of the steering sensor is a feedback result of calibrating the steering wheel angle signal, if the value is true, the calibration of the steering wheel angle sensor is proved to be successful, otherwise, the state of the steering wheel angle sensor is proved to be abnormal; the third preset angle/the fourth preset angle is the maximum steering angle at which the turning auxiliary lighting is turned off, and if the third preset angle/the fourth preset angle is smaller than the maximum steering angle, a turning auxiliary lighting turning-off request is sent.
Step S3: a low beam state of the vehicle is detected. I.e. whether the low beam is in the on-state or the off-state. Specifically, as shown in fig. 1, the low beam state can be detected by whether a low beam automatic request signal is received, and if the low beam automatic request signal is received, it indicates that the low beam is in an on state, that is, the external environment is at night or in an environment with poor light, and the low beam needs to be turned on to illuminate; otherwise, the automatic request signal of the dipped headlight is not received, which indicates that the dipped headlight is in the off state, i.e. the external environment is in the daytime or in the environment with better light at the moment, and the dipped headlight does not need to be turned on for illumination.
Step S4: and controlling turning auxiliary corner lamps of the vehicle to be turned on or off according to the low beam lamp state and the turning auxiliary lighting on or off request.
In one embodiment of the present invention, as shown in fig. 6, controlling turning assist winkers of a vehicle to turn on or off according to a low beam state and a turning assist lighting on or off request includes: when the dipped headlight is in an on state, controlling turning auxiliary corner lamps of the vehicle to be turned on or off according to turning auxiliary lighting on or off requests; when the low beam light is in the off state, the turning auxiliary lighting on or off request is not responded. That is, it is possible to activate the adaptive turn assist lighting function, i.e., to control turn assist winkers of the vehicle to turn on or off in response to a turn assist lighting turn-on or turn-off request, only on the premise that the dipped headlight is in an on state; otherwise, i.e. when the dipped headlight is in the off state, the adaptive turn on or turn off assist lighting function is not activated, i.e. no turn assist lighting on or off request is responded to. That is, whether or not the adaptive turning auxiliary lighting function is activated is determined in accordance with the low beam light on request, the turning auxiliary lighting automatic on request, and the turning auxiliary lighting automatic off request. The automatic request of the dipped headlight is determined by the current running environment brightness and working condition of the vehicle, and the dipped headlight turn-on request signal is given after the signal is comprehensively processed after the detection of the light rainfall sensor.
In summary, the implementation of the vehicle turning auxiliary lighting control method according to the embodiment of the present invention mainly includes three parts, namely, turning auxiliary lighting automatic on, turning auxiliary lighting automatic off, and adaptive auxiliary lighting state determination. The first part of turning auxiliary lighting is automatically turned on and judged, whether a steering lever command exists or not is judged firstly, and then the vehicle speed effectiveness, the vehicle speed, the steering wheel angle and the calibration state of the steering wheel are jointly judged, wherein whether the steering lever command exists or not affects a set vehicle speed threshold and a set steering angle threshold used in the state judgment. The automatic turning auxiliary lighting starting judgment satisfaction conditions are as follows: the validity of the vehicle speed is true, the vehicle speed is less than a set threshold value, the angle of the steering wheel is greater than a set angle (the angle is only considered in the size, and the actual value is signed number with steering direction), and the calibration state of the steering wheel is true. The meaning is as follows: the vehicle speed is low, and the steering wheel has a certain angle, and the auxiliary lighting function is requested to be started; and the second part of turning auxiliary lighting automatic turn-off judgment is carried out, whether a steering deflector rod command exists or not is judged, and then the vehicle speed effectiveness, the vehicle speed, the steering wheel angle and the calibration state of the steering wheel are jointly judged, wherein the influence of the existence of the steering deflector rod command is that a set vehicle speed threshold and a set steering angle threshold are used during the state judgment. The conditions for determining the automatic turn-off of the turn assist lighting are as follows: the validity of the vehicle speed is false, or the vehicle speed is greater than or equal to a set threshold value, or the angle of the steering wheel is smaller than a set angle (the angle only considers the size, and the actual value is the signed number of the steering direction), or the calibration state of the steering wheel is false. The meaning is as follows: when the vehicle speed is not low or the angle of the steering wheel is insufficient, the auxiliary lighting function is requested to be turned off; the third part of the self-adaptive turning auxiliary lighting judgment has the judgment conditions of a low beam light turning-on request, an auxiliary lighting function turning-on request and an auxiliary lighting function turning-off request, and the self-adaptive turning auxiliary lighting turning-on establishment conditions are as follows: the low beam light turn-on request is true and the auxiliary lighting function is not a turn-off request, and when the auxiliary lighting function is not currently having a turn-on request, the auxiliary lighting function is unchanged and is in an on state. The meaning is as follows: the turn-on and turn-off requests of the auxiliary lighting function are automatically executed according to logic judgment for the self-adaptive turn auxiliary lighting established in the state that the dipped headlight is turned on. Wherein the turn-on request of the low beam is determined by the current ambient brightness of the vehicle, etc.
According to the vehicle turning auxiliary lighting control method, the turning auxiliary corner lamp of the vehicle can be turned on or off in a self-adaptive mode according to the vehicle running information and the low beam state, so that when the vehicle turns at night or in a dark environment, the turning auxiliary corner lamp is intelligently and automatically turned on to turn the vehicle for auxiliary lighting, the low beam is matched to increase the vision of a driver, reduce the vision blind area in the turning process and improve the driving safety; meanwhile, the intelligent automatic turning-off auxiliary corner lamp has enough brightness or turns, so that electric energy is saved, the attention of a driver is not dispersed, and the driving safety is improved.

The vehicle speed validity is a judgment result of whether a collected signal of the vehicle speed is valid or not, if the value is true, the vehicle speed signal is proved to be valid, and if not, the vehicle speed signal is invalid; the third preset vehicle speed/the fourth preset vehicle speed is the lowest vehicle speed value of turning auxiliary lighting, and if the vehicle speed is larger than the lowest vehicle speed value, a turning auxiliary lighting turning-off request is sent; the steering wheel angle validity is a judgment result of whether the collected signal of the steering wheel angle is valid or not, if the value is true, the steering wheel angle validity is proved, otherwise, the steering wheel angle is invalid; the calibration state of the steering sensor is a feedback result of calibrating the steering wheel angle signal, if the value is true, the calibration of the steering wheel angle sensor is proved to be successful, otherwise, the state of the steering wheel angle sensor is proved to be abnormal; the third preset angle/the fourth preset angle is the maximum steering angle at which the turning auxiliary lighting is turned off, and if the third preset angle/the fourth preset angle is smaller than the maximum steering angle, a turning auxiliary lighting turning-off request is sent.
The detection module 130 is used to detect a low beam state of the vehicle. Specifically, the low beam state can be detected by whether a low beam automatic request signal is received, and if the low beam automatic request signal is received, it indicates that the low beam is in an on state, that is, the external environment is at night or in an environment with poor light, and the low beam needs to be turned on to illuminate; otherwise, the automatic request signal of the dipped headlight is not received, which indicates that the dipped headlight is in the off state, i.e. the external environment is in the daytime or in the environment with better light at the moment, and the dipped headlight does not need to be turned on for illumination.
The control module 140 is used to control turning assist winkers of the vehicle to turn on or off according to the low beam state and the turning assist lighting on or off request.
In one embodiment of the present invention, the control module 140 controls turning assist winkers of the vehicle to turn on or off according to the low beam state and the turning assist lighting on or off request, including: when the dipped headlight is in an on state, controlling turning auxiliary corner lamps of the vehicle to be turned on or off according to turning auxiliary lighting on or off requests; when the low beam light is in the off state, the turning auxiliary lighting on or off request is not responded. That is, it is possible to activate the adaptive turn assist lighting function, i.e., to control turn assist winkers of the vehicle to turn on or off in response to a turn assist lighting turn-on or turn-off request, only on the premise that the dipped headlight is in an on state; otherwise, i.e. when the dipped headlight is in the off state, the adaptive turn on or turn off assist lighting function is not activated, i.e. no turn assist lighting on or off request is responded to. That is, whether or not the adaptive turning auxiliary lighting function is activated is determined in accordance with the low beam light on request, the turning auxiliary lighting automatic on request, and the turning auxiliary lighting automatic off request. The automatic request of the dipped headlight is determined by the current running environment brightness and working condition of the vehicle, and the dipped headlight turn-on request signal is given after the signal is comprehensively processed after the detection of the light rainfall sensor.
