Detailed description of the invention
Please refer to Fig. 1, Fig. 1 is the structural representation of the automobile combination meter of the embodiment of the present invention.Automobile combination meter 200 of the present invention comprises CAN(Controller Area Network, controller local area network) transceiver 210, automobile combination meter control unit 220 and read-out 230.Wherein CAN transceiver 210 is responsible for receiving the signal of each electronic system of receiving from CAN bus and those signals being forwarded, in the present embodiment, Automatic Transmission control unit (Transmission ControlUnit, TCU) 110, air conditioner system (Heating, Ventilation and AirConditioning, HVAC) 120 and anti-lock brake system (Anti-locked BrakingSystem, ABS) 130 are all connected with CAN bus 140, this CAN transceiver 210 receives the signal of each electronic system by this CAN bus 140.This CAN transceiver 210 is just passed to this automobile combination meter control unit 220 by them by CAN bus 140 after the signal receiving is processed.
This automobile combination meter control unit 220 is connected to form successively by detection module 221, diversity module 222 and order module 223.Wherein this detection module 221, detects abnormal electronic system signal for each electronic system signal of receiving from CAN bus.This diversity module 222, is connected with this detection module 221, for this abnormal electronic system signal is carried out to classification processing by rule; In the present embodiment, this abnormal electronic system signal that affects drive safety is divided into high priority by this diversity module, and this abnormal electronic system signal that affects driving stability is divided into low priority.This order module 223, is connected with this diversity module 222, for determining through this diversity module 222 classification abnormal electronic system signal after treatment DISPLAY ORDER on read-out 230.The principle of ordering of this order module 223 is in the present embodiment: determine DISPLAY ORDER by the classification results of this diversity module 222, this abnormal electronic system signal that rank is high first shows; When two and determine DISPLAY ORDER by the priority of discovery time when this abnormal electronic system signal belongs to same priority above, discovery time this abnormal electronic system signal early first shows.
This read-out 230 is for showing running information or through the corresponding alarm message of this automobile combination meter control unit electronic system signal after treatment.In the time that this detection module 221 detects this abnormal electronic system signal, demonstration is through this order module 223 abnormal electronic system signal after treatment automatically for this read-out 230, and this read-out 230 is on car running computer in the present embodiment.
Referring to Fig. 2, Fig. 2 is the fundamental diagram of the automobile combination meter of the embodiment of the present invention.Storage battery 300 is powered for this automobile combination meter 200, when ignition lock 400 is during in OFF shelves, read-out 230 on this automobile combination meter 200 does not show any information, but when this ignition lock 400 is not during in OFF shelves, the read-out 230 on this automobile combination meter 200 will show running information or alarm message.Wherein running information comprise average ground speed, outdoor temperature, average fuel consumption, instantaneous oil consumption, can continual mileage; Alarm message comprises each system failure information, mainly contains the system failure information such as engine management system, air bag system, anti-lock brake system, intelligent key system, electronic brake (Electrical Park Brake, EPB) system.
The method of the automatic display alarm information of this automobile combination meter as shown in Figure 3.In the time there is no fault, what on read-out 230, show is running information, if now the detection module 221 in this combination instrument control unit 220 has been found abnormal electronic system signal, while namely having found electronic system in bad order, just indicate failure message input, this diversity module 222 will further confirm which kind of priority is these electronic systems in bad order belong to, and the result of classification processing passed to this order module 223.This order module 223 will judge through this diversity module 222 classification failure message after treatment whether only have a kind of priority, if only have a kind of priority, determine DISPLAY ORDER according to the priority of time, before discovery time coming early, after the coming of discovery time evening.Exist with the failure message that belongs to low priority if belong to the failure message of high priority simultaneously, first show that the failure message of high priority shows the failure message of low priority again.Show in these read-out 230 cocycles through the sorted failure message of this order module 223.
This detection module 221, this diversity module 222 and this order module 223 are periodical dutys, so just can allow chaufeur grasp real-time vehicle-state, so in the time of this its Failure elimination of electronic system in bad order, this failure system has just no longer shown deserved alarm message.For some failure message, this automobile combination meter 200 can be to chaufeur with operation indicating, as " please close boot " etc.
This automobile combination meter 200 also comprises switch key, and for the running information and the alarm message that are presented on this read-out 230 are switched, concrete grammar refers to Fig. 4.Fig. 4 is that the automobile combination meter of the embodiment of the present invention switches the logical diagram showing, in the time that this automobile combination meter 200 shows running information, chaufeur can make this automobile combination meter 200 display alarm information by pressing switch key, if there is no alarm message, this automobile combination meter 200 does not just show or shows promptings such as " troubles free ".If chaufeur is not pressed switch key, this automobile combination meter 200 just enters the pattern of automatic display alarm information, while namely having failure message input, with regard to display alarm information, just shows running information while thering is no failure message input.In the present embodiment, this switch key can be realized by display format switching (DISP) button on automobile.
Automobile combination meter control unit provided by the invention and comprise that the automobile combination meter of this automobile combination meter control unit and the display control method of automobile combination meter taken into account many information and shown reading property of inconvenience, adopt message level classification processing, and make user can fully understand in time the state of vehicle by the mode that the automatic display alarm information of read-out and user are switched alarm message voluntarily, and carry out corresponding operating, realize good driving habit, improve driving safety coefficient.
With reference to the accompanying drawings of the preferred embodiments of the present invention, those skilled in the art do not depart from the scope and spirit of the present invention above, can have multiple flexible program to realize the present invention.For example, illustrate as the part of an embodiment or the feature described can be used for another embodiment to obtain another embodiment.These are only the better feasible embodiment of the present invention, not thereby limit to interest field of the present invention, the equivalence that all utilizations specification sheets of the present invention and accompanying drawing content are done changes, within being all contained in interest field of the present invention.
