Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
In one embodiment, as shown in fig. 1, a daytime running light driving control method is provided, and this embodiment is exemplified by applying the method to an onboard controller, and it is understood that the method may also be applied to a daytime running light control circuit, and may also be applied to a vehicle body control system including the daytime running light control circuit. In this embodiment, the method includes the steps of:
and 102, acquiring the current driving times.
Specifically, when the vehicle is started, the vehicle-mounted controller selects whether to call the daytime running light drive control or not according to the current vehicle state information. After the daytime running lamp driving control is started to be called, the vehicle-mounted controller firstly clears the driving times, then starts to count the driving times, and adds 1 to the driving times to obtain the current driving times before the daytime running lamp is driven every time so as to count the current driving times of the daytime running lamp.
And step 104, outputting a driving voltage if the current driving frequency is not greater than the driving frequency threshold.
Specifically, a driving frequency threshold is preset in the vehicle-mounted controller, after the current driving frequency is obtained, the current driving frequency is compared with the driving frequency threshold, and if the current driving frequency is not greater than the driving frequency threshold, the vehicle-mounted controller outputs driving voltage to a daytime running lamp driving circuit; and if the current driving times are larger than the driving time threshold, stopping the current driving by the vehicle-mounted controller, and stopping the driving control of the daytime running lamp called at this time.
And 106, monitoring the driving current corresponding to the driving voltage, acquiring the driving current, and comparing the driving current with a driving current threshold value.
Specifically, a driving current threshold is preset in the vehicle-mounted controller, and the vehicle-mounted controller outputs driving voltage to the daytime running lamp driving circuit, monitors the current driving current of the daytime running lamp driving circuit, and compares the current driving current with the driving current threshold.
And step 108, if the driving current is not larger than the driving current threshold value, keeping electrifying, and lighting the daytime running lamp.
Specifically, if the current driving current of the daytime running lamp driving circuit is not greater than the driving current threshold, the vehicle-mounted controller keeps outputting the driving voltage, and the daytime running lamp driving circuit keeps the current driving current to drive and light the daytime running lamp; if the current driving current of the daytime running lamp driving circuit is larger than the driving current threshold value, the driving current at the moment can cause that the transient current of an inductive load in the daytime running lamp is overlarge, and further influences a vehicle-mounted controller, the daytime running lamp driving circuit and other circuits, so that the vehicle-mounted processor stops outputting the driving voltage, interrupts the driving current of the daytime running lamp driving circuit, returns to execute the step of adding 1 to the current driving frequency, and drives once again.
In the daytime running lamp driving control method, the vehicle-mounted controller acquires the current driving times; if the current driving times are not more than the driving times threshold, outputting driving voltage; monitoring a driving current corresponding to the driving voltage, acquiring the driving current, and comparing the driving current with a driving current threshold; and if the driving current is not greater than the driving current threshold value, keeping electrifying and lighting the daytime running lamp. By setting the driving frequency threshold and the driving current threshold, the driving current of the vehicle-mounted controller chip is controlled within a certain range, the phenomenon that the driving current of the vehicle-mounted controller is too large is avoided, the requirement on the vehicle-mounted controller chip is reduced, and therefore the cost of the vehicle-mounted controller is reduced.
In an optional embodiment, if the current driving frequency is greater than the driving frequency threshold, the driving is stopped, and the fault information is sent to the corresponding vehicle-mounted device.
Specifically, if the current driving frequency is greater than the driving frequency threshold, the vehicle-mounted controller stops the driving, terminates the driving control of the daytime running lamp, and uploads the failure information of the daytime running lamp to equipment such as an instrument panel and a display screen of a cab for displaying. When the driving frequency is higher than a normal value, the driving current is higher than a driving current threshold value for many times when the driving of the daytime running lamp is attempted every time, the driving current threshold value is a normal maximum current threshold value set according to an actual vehicle-mounted controller chip and a daytime running lamp driving circuit, the driving current is continuously higher than the driving current threshold value for many times, and faults such as short circuit and the like occur in the daytime running lamp driving circuit or a circuit in the daytime running lamp, so when the driving current is higher than the driving current threshold value for many times, the driving of the daytime running lamp is stopped continuously by counting the driving frequency, and fault reporting is performed, so that the vehicle-mounted controller chip, the daytime running lamp driving circuit and the like are protected.
In this embodiment, the current driving frequency and the driving frequency threshold are compared by the vehicle-mounted controller, and if the current driving frequency is greater than the driving frequency threshold, the current driving is stopped, and the fault information is sent to the corresponding vehicle-mounted device. The purpose of diagnosing the circuit fault according to the magnitude of the driving current can be achieved, and therefore the vehicle-mounted controller chip, the daytime running lamp driving circuit and the internal circuit of the daytime running lamp are protected.
In one embodiment, before acquiring the current driving times, the method further includes: and clearing the current driving times. Acquiring the current driving times, including: adding 1 to the current driving times; and acquiring the driving times after adding 1 as new current driving times.
Specifically, when the vehicle performs a new working cycle, the vehicle-mounted controller determines whether to start the daytime running light drive control according to the current vehicle state. If the daytime running lamp driving control is started, the driving frequency is cleared firstly, then the first driving is started, the driving frequency is added with 1 to obtain the current driving frequency, and then the current driving frequency is compared with the driving frequency threshold. The working cycle refers to the working process of the vehicle from the starting of the engine to the flameout of the engine.
Optionally, the step of resetting the driving times may also be executed after the fault information is sent, the vehicle-mounted controller determines that the current driving times is greater than the driving times threshold, stops the current driving, terminates the driving control of the daytime running lamp, uploads the fault information of the daytime running lamp to the instrument panel, the display screen and other devices of the cab for display, and resets the count of the current driving times.
In one embodiment, if the current driving current is greater than the driving current threshold, the step of adding 1 to the current driving times is returned to be executed.
Specifically, taking daytime running light driving control of one driving cycle as an example for explanation, when the driving frequency is 1, the driving frequency 1 is smaller than a driving frequency threshold (which can be set to 4), at this time, the onboard controller outputs a driving voltage to the monitoring daytime running light driving circuit, the current driving current is monitored to be 20A, the current driving current 20A is greater than a driving current threshold (which can be set to 10A), the step of adding 1 to the current driving frequency is returned to, the onboard controller adds 1 to the current driving frequency to obtain the driving frequency 2, then the driving frequency 2 and the driving frequency threshold 4 are compared again, the driving frequency 2 is smaller than the driving frequency threshold 4, the onboard controller outputs the driving voltage again, and the current driving current is monitored.
In an optional implementation manner, if the driving frequency is 4, the vehicle-mounted controller monitors that the current driving current is 9A, the current is kept on, the daytime running lamp is driven to be turned on, and the driving control of the daytime running lamp is terminated after the daytime running lamp is turned on; if the driving frequency is 4, the vehicle-mounted controller monitors that the current driving current is 22A, the step of adding 1 to the current driving frequency is returned, the vehicle-mounted controller adds 4 to the current driving frequency to obtain a driving frequency 5, at the moment, the driving frequency 5 is greater than a driving frequency threshold value 4, the vehicle-mounted controller stops the driving, the driving control of the daytime running lamp is stopped, and fault information is sent to corresponding vehicle-mounted equipment.
In this embodiment, the current driving current and the driving current threshold are compared by the vehicle-mounted controller, and if the current driving current is greater than the driving current threshold, the step of adding 1 to the current driving frequency is executed. The purpose of controlling and optimizing the driving current of the daytime running lamp can be achieved, and therefore the vehicle-mounted controller chip, the daytime running lamp driving circuit and the internal circuit of the daytime running lamp are protected.
In one embodiment, before acquiring the current driving times, the method further includes: and acquiring vehicle state information, and calling the daytime running lamp driving control if the vehicle state information is a preset vehicle state. The preset vehicle state includes at least one of ignition switch state information, position light switch state information, left and right turn light switch state information, and hazard warning switch state information.
Specifically, each time the vehicle performs a new work cycle, the vehicle-mounted controller starts driving control of the daytime running light according to whether the current vehicle state information satisfies the preset vehicle state. The preset vehicle state specifically includes an ignition switch on, a position light switch off, a left and right turn light switch off, and a hazard warning switch off, and the vehicle-mounted controller may turn on the daytime running light drive control as long as at least one of the preset vehicle states is satisfied. The working cycle refers to the working process of the vehicle from the starting of the engine to the flameout of the engine.
In one embodiment, as shown in fig. 2, a daytime running light driving control method is provided, where the method specifically includes:
step 202, the vehicle-mounted controller starts driving control of the daytime running light.
Specifically, the vehicle-mounted controller starts the daytime running lamp driving control when the current ignition switch of the vehicle is turned on, the position lamp switch is turned off, the left and right turn lamp switches are turned off and the hazard alarm switch is turned off.
And step 204, the vehicle-mounted controller performs drive frequency zero clearing.
Specifically, the vehicle-mounted controller clears the driving times.
In step 206, the vehicle-mounted controller obtains the current driving times.
Specifically, the driving times are counted, and before the daytime running lamp is driven each time, 1 is added to the driving times to obtain the current driving times, so that the current daytime running lamp is counted to be driven for the second time.
In step 208, the onboard controller compares the current drive times to a drive times threshold.
Specifically, a driving frequency threshold is preset in the vehicle-mounted controller, and the driving frequency threshold can be set according to needs, for example, 3 times, 5 times, and the like are not limited thereto. And after the current driving times are obtained, comparing the current driving times with a driving time threshold, and if the current driving times are not more than the driving time threshold, outputting a driving voltage to a daytime running lamp driving circuit by the vehicle-mounted controller. If the current driving frequency is larger than the driving frequency threshold value, the vehicle-mounted controller interrupts the current output driving and terminates the driving control of the driving lamp in the daytime.
Step 210, the onboard controller monitors the driving current and compares the driving current to a driving current threshold.
Specifically, a driving current threshold is preset in the vehicle-mounted controller, and the driving current threshold may be set according to needs, for example, 10A, 12A, etc. are not limited thereto. The vehicle-mounted controller outputs driving voltage to the daytime running lamp driving circuit, monitors the current driving current of the daytime running lamp driving circuit, and compares the current driving current with a driving current threshold value.
Further, if the current driving current of the daytime running lamp driving circuit is not larger than the driving current threshold, the vehicle-mounted controller keeps outputting the driving voltage, and the daytime running lamp driving circuit keeps the current driving current to drive the daytime running lamp at a high end, so that the daytime running lamp is lightened. If the current driving current of the daytime running lamp driving circuit is greater than the driving current threshold, the driving current at this time may cause an excessive transient current of an inductive load inside the daytime running lamp, and further affect the vehicle controller, the daytime running lamp driving circuit, and other circuits, so that the vehicle processor stops outputting the driving voltage, interrupts the high-end driving current of the daytime running lamp driving circuit, returns to execute step 206, and performs driving again.
In step 212, the onboard controller ends the daytime running light drive control.
Specifically, after the vehicle-mounted controller outputs a voltage to light the daytime running lamp, the driving control of the daytime running lamp is ended.
Further, in step 204, when the driving frequency is higher than the driving current threshold, it is described that the driving current is higher than the driving current threshold many times each time the daytime running light is attempted to be driven, and a fault such as a short circuit occurs in the daytime running light driving circuit or the circuit inside the daytime running light, and the vehicle-mounted controller stops the current output driving, terminates the current daytime running light driving control, and performs an error notification, thereby protecting the vehicle-mounted controller chip, the daytime running light driving circuit, the circuit inside the daytime running light, and the like.
In this embodiment, the vehicle-mounted controller starts driving control of the daytime running lamp, first performs drive frequency resetting, then obtains the current drive frequency, compares the current drive frequency with a drive frequency threshold, monitors the drive current, compares the drive current with the drive current threshold, and finally ends driving control of the daytime running lamp. By setting the driving frequency threshold and the driving current threshold, the driving current of the vehicle-mounted controller chip is controlled within a certain range, the phenomenon that the driving current of the vehicle-mounted controller is too large is avoided, the requirement on the vehicle-mounted controller chip is reduced, and therefore the cost of the vehicle-mounted controller is reduced.
In an embodiment, as shown in fig. 3, a daytime running light driving control method is provided, which is exemplified by applying the method to driving left and right daytime running lights, as shown in fig. 4, a vehicle body area controller calls daytime running light driving control for the daytime running lights on the left and right sides, respectively, and simultaneously drives the left and right daytime running lights through the left and right vehicle light controllers, so that the two daytime running lights are synchronously turned on/off, wherein when one side fails or terminates the daytime running light driving control, left or right daytime running light failure information is sent, and the method specifically includes:
the current ignition switch of the vehicle is turned on, the position light switch is turned off, the left and right turn light switches are turned off, the danger alarm switch is turned off, and the vehicle body domain controller simultaneously starts the daytime running light driving control on two sides.
For each side, the body area controller first clears the number of drives n, i.e., n equals 0.
And counting the driving times for each side, adding 1 to the driving times to obtain the current driving times before driving the daytime running lamp each time, namely n is n +1, so as to count the current driving time of the daytime running lamp.
For each side, a driving number threshold value n _ max is preset in the vehicle body area controller, and n _ max can be set to 4 (times) in the embodiment. After the current driving frequency n is obtained, comparing the current driving frequency with a driving frequency threshold, and if n is less than or equal to n _ max, outputting a driving voltage to the left and right side vehicle lamp controllers by the vehicle body domain controller; and if n is more than n _ max, stopping the driving of the vehicle body domain controller, and stopping the driving control of the driving lamp in the daytime. The vehicle body area controller terminates the daytime running light drive control of the side and transmits the fault information of the side to the corresponding vehicle-mounted device.
For each side, a driving current threshold I _ max is preset in the body area controller, and I _ max may be set to 10A (amperes) in this embodiment. And when the vehicle body area controller outputs driving voltage to the left and right side vehicle lamp controllers, monitoring the current driving current I of the left and right side vehicle lamp controllers, and comparing the current driving current with a driving current threshold value. And if the I of the left and right side vehicle lamp controllers is less than or equal to I _ max, the vehicle body domain controller keeps outputting the driving voltage, the left and right side vehicle lamp controllers keep the current driving current to carry out high-end driving on the daytime running lamp, and the left and right daytime running lamps are lightened. If I > I _ max of the left and right side lamp controllers, the driving current at this time causes an excessive transient current of an inductive load in the daytime running lamp, and further affects the body area controller, the left and right side lamp controllers and other circuits, so that the vehicle-mounted processor stops outputting the driving voltage, interrupts the high-end driving current of the left and right side lamp controllers, returns to execute the step n +1, and drives again.
And after the vehicle body area controller outputs voltage to light the left and right daytime running lamps, ending the driving control of the daytime running lamp. Or, when the number of times of driving of one side is higher than the driving current threshold, it is described that the driving current is higher than the driving current threshold many times each time the one side tries to drive the daytime running light, a fault such as a short circuit occurs in the left and right side light controllers of the one side or the circuits inside the daytime running light, the body area controller stops the current output driving, terminates the current daytime running light driving control, and reports an error to the one side, thereby protecting the body area controller chip, the side light controllers, the internal circuits of the side daytime running light, and the like.
In the embodiment, the current driving times are obtained; if the current driving times are not more than the driving times threshold, outputting driving voltage; monitoring a driving current corresponding to the driving voltage, acquiring the driving current, and comparing the driving current with a driving current threshold; and if the driving current is not greater than the driving current threshold value, keeping electrifying and lighting the daytime running lamp. By setting the driving frequency threshold and the driving current threshold, the driving current of the vehicle-mounted controller chip is controlled within a certain range, the phenomenon that the driving current of the vehicle-mounted controller is too large is avoided, the requirement on the vehicle-mounted controller chip is reduced, and therefore the cost of the vehicle-mounted controller is reduced.
