Brief description of the drawings
Fig. 1 is a kind of structural representation of vehicle mileage standby system provided by the utility model;
Fig. 2 is another structural representation of vehicle mileage standby system provided by the utility model.
Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining this Utility model, it is not used to limit the utility model.
As shown in figure 1, it is a kind of structural representation of vehicle mileage standby system provided by the utility model.
In the present embodiment, the vehicle mileage standby system, including:Combination instrument and backup controller, the combination Instrument is connected by CAN with the backup controller.
Wherein, the combination instrument includes:Power supply, CPU, CAN transceiver, display driving, display and memory, power supply Powered for the combination instrument;CPU gathers mileage information, by the total kilometrage information after accumulation calculating in vehicle operation Storage in memory, and sends the first CAN for including the total kilometrage information by CAN transceiver to the backup controller Message;Display driving is used to drive display to show the total kilometrage information;The backup controller receives the first CAN After message, judge whether total kilometrage is more than the currently stored total kilometrage of the backup controller in the message, if it is, renewal The currently stored total kilometrage of the backup controller.Specifically, the combination instrument passes through the pulse signal to odometer sensor Processing is acquired, by CPU computing, is on the one hand stored the mileage number after accumulation calculating into memory, on the one hand will Total kilometrage data are shown by display, while are sent to the total kilometrage data after accumulation calculating by CAN transceiver In CAN buses, after backup controller receives the data of total kilometrage from CAN, enter with the current total kilometrage of oneself storage After row compares, larger total kilometrage is made a backup store according to comparison result.
CPU reads total kilometrage information on vehicle from the memory after electricity, and receives the backup control from CAN The second CAN message for including total kilometrage information that device processed is sent, judge the total kilometrage of total kilometrage information in second CAN message Whether it is more than the total kilometrage of the currently stored total kilometrage information of the memory, is currently deposited if it is, updating the memory The total kilometrage of storage, and show by display the total kilometrage of total kilometrage information in the message.
Specifically, the CPU can control CAN transceiver to send bag to CAN after electricity to set the cycle on vehicle The message of the information containing total kilometrage.For example, the setting cycle can be 100 milliseconds, 500 milliseconds, 1 second or 3 seconds etc., with specific reference to Depending on actual demand.The memory can be flash, EEPROM, phase transition internal memory PCM, dynamic random access memory Mixing internal memory of DRAM, PCM and DRAM composition etc., is not limited herein.Preferably, the memory is electric erazable programmable Read-only storage.
The backup controller can be a controller being separately provided or be integrated in other controllers, As long as the backup controller can be realized:Believe 1. receiving the combination instrument from CAN and being sent to CAN comprising total kilometrage The message of breath;2. judge whether the total kilometrage number of total kilometrage information in the message is more than currently stored total of the backup controller Mileage number, and store larger total kilometrage number;3. sending these three functions comprising the message of total kilometrage information to CAN is Can.For example, the backup controller can send the message for including mileage information on vehicle to CAN after electricity.Further Ground, the backup controller can be within a specified time sent comprising inner on vehicle after electricity with some cycles to CAN The message of journey information, for example, some cycles can be 100 milliseconds, 500 milliseconds, 1 second or 3 seconds etc., the specified time can be with For 1 second, 10 seconds, 1 minute, 3 minutes, 10 minutes etc., depending on actual demand.So can simply it realize described Combination instrument receives the function for the message comprising mileage information that the backup controller is sent from CAN, and avoids described Backup controller does not stop to send the situation of the message comprising mileage information to CAN on vehicle during electricity, saves energy.
The display include it is following any one or more:LCDs and instrument.In addition, the display may be used also To further comprise indicator lamp, alarm lamp etc., will not be described in detail herein.
In a specific embodiment, the backup control that vehicle mileage standby system includes combination instrument and is separately provided Device processed, vehicle every time on it is electric when, the CPU of combination instrument can deposit its currently stored total kilometrage information and backup controller The total kilometrage information of storage is compared, the larger value after updating and showing both relatively.
Vehicle mileage standby system provided by the utility model includes:Combination instrument and backup controller, the combination instrument Table is connected by CAN with the backup controller.Because the combination instrument passes through CAN and the backup controller It is connected, the combination instrument sends the message for including total kilometrage information, the backup by CAN to the backup controller The mileage number of its storage of controller real-time update, thus when the combination instrument loses mileage, the combination instrument can To recover mileage number data by the backup controller, efficiently solve when combination instrument damages, be not easy or even can not obtain A problem of traveling of picking up the car amounts to mileage.
As shown in Fig. 2 it is another structural representation of vehicle mileage standby system provided by the utility model.
In the present embodiment, the backup controller include it is following any one:Car body controller, engine controller, Air-conditioner controller, air spring control, Tachographs etc..Extra increase backup controller can so not had to, so as to reduce into This is in order to promoting.Preferably, the backup controller is car body controller.The memory is deposited for electric erazable programmable is read-only Reservoir.The display is LCDs.
In order to further save energy, and occupancy of the backup controller to Internet resources is reduced, the CPU is whole After Che Shang electricity total kilometrage information request message is sent to the backup controller;The backup controller receives the total kilometrage After information request message, the second CAN message for including total kilometrage information is sent to the CPU.The backup can so be avoided Controller does not stop to send the situation of the message comprising mileage information to CAN on vehicle during electricity, saves energy, and Excessive CAN resource will not be taken.
Correspondingly, the utility model additionally provides a kind of automobile, including vehicle mileage standby system as described above.
Although the utility model combination above example is described, the utility model is not limited to above-mentioned reality Example is applied, and is only limited by claim, particularly with the embodiment part of automobile, is referred to vehicle mileage standby system, It is not described in detail.Those of ordinary skill in the art easily can modify and change to it, but and new without departing from this practicality The essential idea and scope of type.
