The object implemented for making the utility model, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, are further described in more detail the technical scheme in the utility model embodiment.In the accompanying drawings, same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Described embodiment is the utility model part embodiment, instead of whole embodiments.Be exemplary below by the embodiment be described with reference to the drawings, be intended to for explaining the utility model, and can not be interpreted as restriction of the present utility model.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
In description of the present utility model, it will be appreciated that, term " " center ", " longitudinal direction ", " transverse direction ", " front ", " afterwards ", " left side ", " right side ", " vertically ", " level ", " top ", " end " " interior ", orientation or the position relationship of the instruction such as " outward " are based on orientation shown in the drawings or position relationship, only the utility model and simplified characterization for convenience of description, instead of indicate or imply that the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore the restriction to the utility model protection domain can not be interpreted as.
The utility model provides a kind of entire car controller, comprises MCU and security drive module, and when described MCU lost efficacy, described security drive module work, Direct driver safety feature worked.
Above-mentioned entire car controller, when MCU lost efficacy, can work by Direct driver safety feature (such as brake lamp, side-marker lamp, high beam, front wiper etc.), thus improves the security of vehicle.
Fig. 1 is the schematic circuit according to the MCU in the entire car controller of the utility model first embodiment and security drive module.Entire car controller shown in Fig. 1 comprises MCU 1 and security drive module 2.
An I/O port (being positioned at port or the pin on right side) of MCU is connected with power supply by pull-up resistor R.In illustrated circuit, the voltage of power supply is 5V, but is understandable that, the utility model is not limited thereto, and such as, can also be set to 12V or 24V etc.The resistance of pull-up resistor R can be arranged as required.Such as, the resistance of pull-up resistor is set to 100 ohm or 1k ohm.Under MCU normal operating conditions, described I/O port output low level, thus security drive module does not work.Under MCU failure state, described I/O port does not export, and now, the voltage of I/O port is driven high, and concrete voltage herein is also subject to the impact of the particular circuit configurations of security drive module.Be understandable that, the signal that I/O port exports can be understood as " Limp Home (limp-home) " and represents signal.That is, when MCU lost efficacy, limp-home state was entered.
Security drive module 2 has limp-home control signal input port (port on the left of it or stitch).The described limp-home control signal input port of security drive module 2 is connected with power supply by pull-up resistor R.When the voltage of limp-home control signal input port is high, security drive module 2 works, and sends safe control signal, directly controls safety feature work.That is, signal is sent to control the operation of safety feature independent of MCU.Be understandable that, concrete control mode or send signal type (digital signal, simulating signal or drive voltage signal etc.) can arrange as required.Advantageously, when the voltage of described I/O port is driven high, Engine ECU is connected with gas pedal by described security drive module.Thus, make it possible to by the control to gas pedal, steering vehicle, slowly travel and go home or garage.
In the utility model, safety feature refers to the device with vehicle safety with close relation.Most typical safety feature is brake lamp, side-marker lamp and/or high beam, this kind of instruction vehicle-state of steering indicating light and position, avoids the pilot lamp that back car collides.In addition, the safety feature in the utility model also comprises drive unit, the Engine ECU and gas pedal coupling arrangement etc. of front wiper and so on.
The specific implementation form of security drive module 2 can adopt various ways.In one embodiment, described security drive module is TLE7239LS chip.In alternative mode, described security drive module is relay module.
Fig. 2 is the schematic circuit according to the security drive module in the entire car controller of the utility model second embodiment.Security drive module 2 in Fig. 2 is relay module, comprises relay coil KA, the first K switch 1, second switch K2, the 3rd K switch 3 and the 4th K switch 4.
The positive terminal of relay coil KA is connected by the power supply of pull down resistor R and 12V, and negative pole end is connected to ground.When the positive terminal of relay coil KA is driven high, relay coil KA is passed to drive current.
When relay coil KA is passed to drive current, adhesive first K switch 1, second switch K2, the 3rd K switch 3 and the 4th K switch 4.First K switch 1 is connected with brake lamp L1, then is connected between 12V power supply and ground.Second switch K2 connects with side-marker lamp L2, then is connected between 12V power supply and ground.3rd K switch 3 is connected with high beam L3, then is connected between 12V power supply and ground.Thus when the first K switch 1, second switch K2, the 3rd K switch 3 close, brake lamp L1, side-marker lamp L2 and high beam L3 work is lighted, and provides instruction, avoid the generation of the accidents such as collision to other vehicles or personnel.4th K switch 4 is connected between Engine ECU and gas pedal.Thus, when the 4th K switch 4 closes, Engine ECU and gas pedal are coupled together, control engine by gas pedal direct (walking around MCU), realize limp-home.That is, when the voltage of the I/O port of MCU is driven high, Engine ECU is connected with gas pedal by described security drive module.
It is pointed out that the quantity of the switch controlled by relay coil KA is not limited to above-mentioned quantity.And can more or less switch be set as required.Such as, a switch can also be set to control front wiper.
Above-mentioned entire car controller is applied to vehicle (electric motor car or hybrid electric vehicle), the security of vehicle when MCU fault can be improved, even realize limp-home.
Finally it is to be noted: above embodiment only in order to the technical solution of the utility model to be described, is not intended to limit.Although be described in detail the utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of the utility model.
