Example 1
Fig. 1 is a flowchart of a method for switching a display mode of a vehicle-mounted device, which is provided in an embodiment of the present invention, and the method may be implemented by a switching device of a display mode of a vehicle-mounted device, where the switching device of a display mode of a vehicle-mounted device is configured in a vehicle body controller and may be implemented in a hardware and/or software manner. The Body Controller (BCM), also called a body computer, is an Electronic Control Unit (ECU) for controlling an electric system of a vehicle body in an automotive engineering, and is one of important components of the vehicle. As shown in fig. 1, the method includes:
S101, collecting current resistance information of at least one vehicle lamp in a target vehicle at the current moment.
The vehicle body controller periodically collects current resistance information of at least one vehicle lamp in the target vehicle according to a preset time interval, namely, after the resistance information of the vehicle lamp is collected at a certain moment, the resistance information of the vehicle lamp is collected again after the time interval passes, and the time interval can be set and adjusted according to actual experience and service requirements. The current time represents the latest collection time, and correspondingly, the current resistance information represents the resistance information of at least one vehicle lamp collected at the current time.
The target vehicle means any vehicle equipped with a vehicle lamp, including, but not limited to, a vehicle of a car, SUV, MPV, or the like. The vehicle lamp includes, but is not limited to, a low beam, a high beam, a fog light, a back taillight, an in-vehicle atmosphere light, or an in-vehicle button backlight of the target vehicle, and the like, and the embodiment is not limited to a specific type and a specific number of vehicle lamps, and the target vehicle may include only one vehicle lamp or may include a plurality of vehicle lamps.
The current resistance information indicates resistance information corresponding to each vehicle lamp at the current moment, and according to experience, the resistance information of the vehicle lamp is an analog signal, and as the vehicle lamp is changed from a closed state to an open state, the temperature of the lamp can gradually rise, so that the resistance information can be continuously increased along with the time.
In one embodiment, the body controller collects current resistance information of each vehicle lamp at the current moment through a CAN bus of the target vehicle. Optionally, the vehicle body controller collects current resistance information corresponding to the dipped headlight, the high beam, the fog lamp and the button backlight in the vehicle respectively through the CAN bus of the target vehicle at the current moment.
S102, determining the current working state of each vehicle lamp according to the current resistance information and the resistance threshold information respectively associated with each vehicle lamp.
The resistance value information of each vehicle lamp changes along with the change of each vehicle lamp from the off state to the on state, so that the relevant resistance value threshold value information is respectively set for each vehicle lamp according to practical experience and is used for judging whether each vehicle lamp is in the off state or in the on state by utilizing the resistance value threshold value information. The current working state refers to the working state of each vehicle lamp at the current moment, and comprises an on state and an off state.
In one embodiment, after the vehicle body controller acquires current resistance information corresponding to each vehicle lamp through the CAN bus, respectively acquiring the resistance threshold information respectively associated with each vehicle lamp, and further, performing numerical comparison according to the current resistance information corresponding to each vehicle lamp and the resistance threshold information, so as to determine the current working state of each vehicle lamp.
For example, assuming that the current resistance information of the fog lamp in the target vehicle is Mx3 and the resistance threshold information associated with the fog lamp is M3, the numerical comparison is performed according to M3 and Mx3, so as to determine whether the fog lamp is in an on state or an off state.
For example, assuming that the current resistance information of the button backlight in the vehicle is Mx1 and the resistance threshold information associated with the button backlight in the vehicle is M1, the numerical comparison is performed according to M1 and Mx1, so as to determine whether the button backlight in the vehicle is in an on state or an off state.
S103, generating current digital signals corresponding to the vehicle lamps according to the current working state, and sending the current digital signals to a vehicle machine in the target vehicle, wherein the vehicle machine switches a display mode according to the current digital signals.
The vehicle body controller generates corresponding current digital signals according to the current working states of the vehicle lamps, and the current digital signals are used for identifying the current working states of the associated vehicle lamps. The car machine refers to a vehicle-mounted information service terminal installed inside a target vehicle for displaying various information such as navigation information, weather information, vehicle status information, multimedia information, and the like to a driver of the target vehicle. The vehicle machine is preset with a plurality of fixed display modes before leaving the factory, and the display modes are used for displaying information in diversified styles according to different brightness values, color values and interface styles, wherein the display modes include, but are not limited to, a high brightness mode, a low brightness mode, a sport mode, a comfort mode and the like, and the specific types of the display modes are not limited in this embodiment.
In one embodiment, the vehicle body controller generates a current digital signal corresponding to each vehicle lamp according to the current working state of each vehicle lamp and the association relation between the current working state of each vehicle lamp and the current digital signal, wherein the association relation between the current working state of each vehicle lamp and the current digital signal is calibrated in advance.
For example, if the operating state of the in-vehicle button backlight of the target vehicle is an off state, a current digital signal "N11" corresponding to the in-vehicle button backlight is generated, and if the operating state of the in-vehicle button backlight of the target vehicle is an on state, a current digital signal "N12" corresponding to the in-vehicle button backlight is generated.
For example, the current digital signal "N21" corresponding to the low beam is generated assuming that the current operating state of the low beam of the target vehicle is an off state, and the current digital signal "N22" corresponding to the low beam is generated assuming that the current operating state of the low beam of the target vehicle is an on state.
For example, the current digital signal "N31" corresponding to the low beam is generated assuming that the current operating state of the fog lamp of the target vehicle is an off state, and the current digital signal "N32" corresponding to the low beam is generated assuming that the current operating state of the fog lamp of the target vehicle is an on state.
Wherein, the current digital signals "N11", "N12", "N21", "N22", "N31" and "N32" each represent a different digital signal.
The vehicle body controller sends the current digital signals corresponding to the vehicle lamps to the vehicle machine through the CAN bus. After the vehicle machine obtains the current digital signals corresponding to the vehicle lamps through the CAN bus, determining a target display mode from the candidate display modes according to the current digital signals corresponding to the vehicle lamps to perform mode switching. It can be understood that, because the current digital signal of each vehicle lamp is determined according to the current working state of each vehicle lamp, and the current working state of each vehicle lamp is related to the running environment of the target vehicle, that is, the display mode of the vehicle machine is essentially switched according to different running environments of the target vehicle, so that the vehicle can make different intelligent linkage along with the running environment change of the target vehicle, the display mode is automatically switched, and the vehicle using experience of drivers and passengers is greatly improved.
According to the technical scheme, the current resistance information of at least one vehicle lamp in the target vehicle is acquired at the current moment, the current working state of each vehicle lamp is determined according to the current resistance information and the resistance threshold information respectively associated with each vehicle lamp, the current digital signal corresponding to each vehicle lamp is generated according to the current working state, the current digital signal is sent to a vehicle machine in the target vehicle, and the vehicle machine switches the display mode according to the current digital signal; in the second aspect, as different intelligent linkages are made according to different working states of the vehicle lamps by the vehicle opportunity, the display mode is automatically switched, so that the intelligence and the real-time performance of the switching of the display mode of the vehicle are improved; in the third aspect, the display modes of the automobile and the motorcycle are automatically switched in the whole course, so that manual intervention is not needed, the operation convenience of drivers and passengers is improved, the potential safety hazards caused by operation distraction are avoided, and the driving safety is improved.
Example two
Fig. 2 is a flowchart of a method for switching a display mode of a vehicle-mounted device according to a second embodiment of the present invention, where the embodiment further optimizes and expands the foregoing embodiment, and may be combined with the foregoing various optional embodiments. As shown in fig. 2, the method includes:
S201, current resistance information of at least one vehicle lamp in the target vehicle is collected at the current moment.
S202, matching current resistance information of each vehicle lamp with resistance threshold information associated with each vehicle lamp respectively; and determining the current working state of each vehicle lamp according to the matching result.
In one embodiment, the vehicle body controller is used for matching the current resistance information of each vehicle lamp with the resistance threshold information associated with each vehicle lamp, comparing the magnitude relation between the current resistance information of each vehicle lamp and the resistance threshold information, and further determining the current working state of each vehicle lamp according to the matching result.
The current resistance information of each vehicle lamp is respectively matched with the resistance threshold information associated with each vehicle lamp, and the current working state of each vehicle lamp is determined according to the matching result, so that the effect of identifying the current working state of each vehicle lamp is realized, and the vehicle lamp can be realized only by collecting the current resistance information of each vehicle lamp, and the vehicle lamp is convenient and quick.
Optionally, determining the current working state of each vehicle lamp according to the matching result includes:
Determining that the current working state of any vehicle lamp is an on state under the condition that the current resistance information of the vehicle lamp is greater than or equal to the resistance threshold information associated with the vehicle lamp; and under the condition that the current resistance information of any vehicle lamp is smaller than the resistance threshold information associated with the vehicle lamp, determining that the current working state of the vehicle lamp is a closed state.
The method comprises the steps that as the resistance information of each vehicle lamp gradually increases from the off state to the on state, the relevant resistance threshold information is set for each vehicle lamp according to practical experience and used for comparing the magnitude relation between the resistance threshold information and the current resistance information, and when the current resistance information of any vehicle lamp is greater than or equal to the resistance threshold information relevant to the vehicle lamp, the current working state of the vehicle lamp is judged to be the on state; and when the current resistance information of any vehicle lamp is smaller than the resistance threshold information associated with the vehicle lamp, judging that the current working state of the vehicle lamp is in a closed state.
For example, assuming that the current resistance information of the fog lamp in the target vehicle is Mx3 and the resistance threshold information related to the fog lamp is M3, if the current resistance information Mx3 is more than or equal to the resistance threshold information M3, determining that the current working state of the fog lamp is an on state; if the current resistance value information Mx3 is smaller than the resistance value threshold value information M3, determining that the current working state of the fog lamp is the off state.
For example, assuming that current resistance information of the button backlight in the vehicle in the target vehicle is Mx1 and resistance threshold information associated with the button backlight in the vehicle is M1, if the current resistance information Mx1 is greater than or equal to the resistance threshold information M1, determining that the current working state of the button backlight in the vehicle is an on state; if the current resistance value information Mx1 is smaller than the resistance value threshold value information M1, determining that the current working state of the button backlight lamp in the vehicle is in a closed state.
Determining that the current working state of any vehicle lamp is an on state under the condition that the current resistance information of the vehicle lamp is greater than or equal to the resistance threshold information associated with the vehicle lamp; under the condition that the current resistance information of any vehicle lamp is smaller than the resistance threshold information associated with the vehicle lamp, the current working state of the vehicle lamp is determined to be the off state, so that the current working state of each vehicle lamp is rapidly identified by utilizing a threshold matching mode, the efficiency of the whole method flow is greatly improved, the time consumption required by the switching of the display modes of the vehicle and the machine is reduced, the timeliness of the switching of the modes of the vehicle and the machine is improved, and the vehicle using experience of a user is improved.
S203, generating current digital signals corresponding to the vehicle lamps according to the current working state.
S204, determining historical digital signals corresponding to the vehicle lamps generated at the last historical moment, and comparing the historical digital signals corresponding to the vehicle lamps with the current digital signals.
The historical time is the collection time adjacent to the current collection time and before the current time, and the corresponding historical digital signal is determined by the following modes: the method comprises the steps of determining historical resistance information of at least one vehicle lamp in a target vehicle at historical moment, determining historical working states of all vehicle lamps according to the historical resistance information and resistance threshold information respectively associated with all vehicle lamps, and generating historical digital signals corresponding to all vehicle lamps according to the historical working states.
In one embodiment, the vehicle body controller acquires, from a memory of the target vehicle, a history digital signal corresponding to each vehicle lamp at a history time, and compares the history digital signal corresponding to each vehicle lamp with a current digital signal corresponding to each vehicle lamp.
For example, assuming that the current digital signals of the in-vehicle button backlight, low beam light, and fog light in the target vehicle are "N11", "N21", and "N31", respectively, the current digital signals are "H11", "H21", and "H31", respectively, the "N11" is compared with "H11", the "N21" is compared with "H21", and the "N31" is compared with "H31".
Optionally, after comparing the historical digital signal and the current digital signal corresponding to each vehicle lamp respectively, the method further includes:
And discarding the current digital signal and collecting the resistance information of the vehicle lamp again at the next moment under the condition that the historical digital signal and the current digital signal respectively corresponding to each vehicle lamp are the same.
For example, continuing the explanation given by way of the above example, assuming that "N11" and "H11", "N21" and "H21", "N31" and "H31" are the same, the in-vehicle button backlight, dipped headlight and fog lamp in the target vehicle are indicated, the historical operating state at the historical time is the same as the current operating state at the current time, that is, the running environment of the target vehicle at the historical time is the same as the running environment at the current time, that is, the display mode to be switched by the vehicle at the current time is the same as the display mode to be switched by the vehicle at the historical time, so that there is no need to control the vehicle to switch the display mode again, the current digital signal is discarded, and the resistance information of the vehicle lamp is collected again at the next time (collection time).
Under the condition that the historical digital signals and the current digital signals corresponding to the vehicle lamps are the same, discarding the current digital signals and collecting the resistance information of the vehicle lamps again at the next moment, on one hand, nonsensical display mode switching of the vehicle and the machine is avoided, smooth information display of the vehicle and the machine is ensured, and on the other hand, the storage pressure of the target vehicle can be relieved by discarding the current digital signals.
S205, under the condition that the historical digital signal and the current digital signal respectively corresponding to any vehicle lamp are different, the current digital signal is sent to the vehicle machine, and the vehicle machine switches the display mode according to the current digital signal.
Under the condition that a historical digital signal and a current digital signal which are respectively corresponding to any vehicle lamp are different, the historical working state of the vehicle lamp at the historical moment is different from the current working state at the current moment, namely the running environment of a target vehicle at the historical moment is not identical to the running environment at the current moment, namely the display mode to be switched by the vehicle at the current moment is not identical to the display mode to be switched by the vehicle at the historical moment, so that the vehicle body controller sends the current digital signal to the vehicle, and the vehicle supply machine switches the display mode according to the current digital signal.
According to the method, under the condition that the historical digital signal and the current digital signal which are respectively corresponding to any vehicle lamp are different, the current digital signal is sent to the vehicle, and the vehicle is provided with the vehicle to switch the display mode according to the current digital signal, so that the vehicle is controlled to switch the display mode only under the condition that the historical digital signal and the current digital signal of at least one vehicle lamp are different, the meaningless vehicle display mode is prevented from being switched, and smooth information display of the vehicle is ensured.
Optionally, sending the current digital signal to a vehicle machine in the target vehicle includes:
And determining whether the vehicle is in a starting state, and if so, transmitting the current digital signal to the vehicle.
In one embodiment, the vehicle body controller determines whether the vehicle is in a starting state, and if the vehicle is in the starting state, the vehicle body controller sends a current digital signal to the vehicle through the CAN bus; if the vehicle is in the power-off state, stopping the sending operation of the current digital signal, determining the state of the vehicle in real time, and if the vehicle is detected to be in the power-on state, triggering the sending operation of the current digital signal again, namely sending the current digital signal to the vehicle through the CAN bus.
By determining whether the vehicle is in a starting state or not, if so, the current digital signal is sent to the vehicle, so that the current digital signal is sent only when the vehicle is in the starting state, namely, the vehicle is controlled to switch the display mode only in the state that the vehicle normally displays information, meaningless digital signal sending is avoided, the burden is brought to data transmission in the vehicle, and the smoothness of the whole method flow is guaranteed.

The vehicle-mounted information service terminal is used for displaying various information, such as navigation information, weather information, vehicle state information, multimedia information and the like, for a driver of the target vehicle. As shown in fig. 3, the method includes:

The current digital signals are determined according to the current working states of the vehicle lamps, and the current working states are determined according to the current resistance information of the vehicle lamps.
In one embodiment, the vehicle body controller collects current resistance information of each vehicle lamp through a CAN bus of the target vehicle at the current moment, respectively obtains resistance threshold information respectively associated with each vehicle lamp, and further performs numerical comparison according to the current resistance information and the resistance threshold information corresponding to each vehicle lamp to determine the current working state of each vehicle lamp. And finally, generating current digital signals corresponding to the vehicle lamps according to the current working states of the vehicle lamps and the association relation between the current working states of the vehicle lamps and the current digital signals, and sending the current digital signals corresponding to the vehicle lamps to the vehicle machine through the CAN bus.
