The specific embodiment
To combine accompanying drawing to describe the preferred embodiments of the present invention in detail below, identical in the accompanying drawings reference number is represented components identical.
Fig. 1 is the structural representation according to automobile auxiliary security control system of the present invention.As shown in the figure; This system comprises automobile auxiliary security control module 1 (Safety Assistant ControlModule; SAM), engine management system 2 (Engine Management System, EMS), anti-skid brake system 3 (Anti-Lock Braking System, ABS), inside rear-view mirror module 4 (Interior mirror Module; IMM) and gauge panel 5 (Instrument Pack, IPK).Wherein EMS, ABS, IMM, IPK and SAM are through the CAN bus communication.The parts that those skilled in the art can carry out communication according to actual increase or minimizing and automobile auxiliary security control module 1 have only schematically been described among the figure and being connected of automobile auxiliary security control module 1 of the present invention and above-mentioned parts.
Fig. 2 is the structural representation of SAM.As shown in the figure, SAM comprises signal conditioning communication module 10, active speed limit (Active speed limitation, ASL) module 11 and back seat belt monitoring module 12.Wherein SAM carries out data exchange through other parts of car load among signal conditioning communication module 10 and Fig. 1 through the CAN bus.
Signal conditioning communication module 10 is used for the signal from ASL module 11 and back seat belt monitoring module 12 is converted into and can afterwards signal be sent to associated components among Fig. 1 through the signal of CAN bus transfer.
ASL module 11 comprises that ASL enable/disable module 110, the speed of a motor vehicle are provided with module 111, speed of a motor vehicle comparison module 112 and throttle comparison module 114.
Back seat belt monitoring module 12 comprises monitoring enable/disable module 120, first detector 121, second detector 122, the 3rd detector 123.
Table 1 illustrates according to the signal and communication between other parts among SAM module of the present invention and Fig. 1.
Table 1
To combine Fig. 1-2 and table 1 to introduce the workflow of automobile supplementary security system of the present invention in detail below.
ASL enable/disable module 110 is used for the ASL enable/disable request of being sent according to the input media (not shown), thereby generate and send the said speed of a motor vehicle of ASL enable/disable signal enable/disable module, said speed of a motor vehicle comparison module and said throttle position comparison module is set.Simultaneously alternatively, ASL enable/disable module 110 is sent signal ASL_switch_sts to EMS and IPK, in order to the startup of this ASL module of notice EMS, and on IPK, illustrates in order to remind the user that this function is opened with the mode of buzzing or demonstration.
The speed of a motor vehicle is provided with module 111 and sets restricted speed ASL_limited_speed and send it to speed of a motor vehicle comparison module 112 through the input media (not shown).Preferably, restricted speed is at 30km/h-130km/h.Simultaneously this restricted speed is sent to EMS and makes EMS know the demand velocity constraint that the user is actual, under the different operating modes, certain compensation or restriction are done in engine torque output in software strategy, and auxiliary ASL realizes the target of the control speed of a motor vehicle.Alternatively, restricted speed ASL_limited_speed is sent to instrument IPK 5 in order to synchronously to show restricted speed numerical value ASL_limited_speed through signal conditioning communication module 10.
Preferably, can restricted speed directly be stored in the speed of a motor vehicle module 111 is set, make when using system of the present invention next time, need not the duty limited import speed of a motor vehicle once more.
Speed of a motor vehicle comparison module 112 receives actual vehicle speed Vehicle_speed through the signal conditioning communication module from ABS 3; Compare restricted speed and actual vehicle speed; When actual vehicle speed during greater than the restricted speed predetermined value; Send ASL activation signal ASL_active to EMS 2, otherwise continue relatively restricted speed and actual vehicle speed.Preferably, this predetermined value is for being not more than 3km/h.Alternatively, speed of a motor vehicle comparison module can also send ASL alarm signal A SL_limited_buzzer to IPK 5, makes instrument IPK receive the continuous audible alarm of beginning after the ASL alerting signal.Alternatively, in this step, ABS 3 can also send actual vehicle speed Vehicle_speed to IPK 5, in order to synchronously to show the restriction actual vehicle speed.
Next said throttle position comparison module 113 carries out following steps:
The current throttle position signal Current_pedal_position of A, the expression current throttle position that receives from EMS 2;
B, the current throttle position signal is remained limit throttle position signal Limited_pedal_position;
Next current throttle position signal Current_pedal_position constantly of C, next throttle position constantly of reception expression;
D, next current throttle position signal Current_pedal_position and limit throttle position signal Limited_pedal_position constantly of comparison.
If next current throttle position signal Current_pedal_position constantly of E is greater than limit throttle position signal Limited_pedal_position; Then send limit throttle position signal Limited_pedal_position and ASL activation signal ASL_active to EMS, thereby this EMS response ASL activation signal is so that control fuel charge and return steps A according to limit throttle position signal Limited_pedal_position control throttle; Otherwise send ASL un-activation signal ASL_passive to EMS, EMS response this moment ASL un-activation signal ASL_passive is according to true accelerator open degree output torque.
In addition,, close the ASL function, make the restriction of the no longer restricted speed of a motor vehicle of vehicle thereby generate the ASL inhibit signal when ASL enable/disable module 110 receives Das Gaspedal when quickening (being that the Das Gaspedal aperture is 100%) signal Kick_down entirely from EMS.Alternatively, also signal Kick_down is sent to IPK5, the mode that perhaps shows with buzzing illustrates on IPK to remind user ASL that function is closed.
The principle of work of back seat belt monitoring module 12 enables first to the 3rd detector 121-123 at first sending the request of monitoring enable/disable to monitoring enable/disable module 120 through the input media (not shown) thereby monitoring enable/disable module generates monitoring enable/disable signal.Alternatively, also will monitor enable/disable signal Main_switch_sts and be sent to IPK and/or IMM, in order to On/Off to this function of user prompt.
For common automobile; General back row has three seats; When first detector 121 detects left side seat and does not fasten the safety belt, send RL_buckle_switch_sts to IMM and/or IPK, do not fasten the safety belt in order to remind the left side seat of arranging behind the user.When second detector 122 detects central seat and does not fasten the safety belt, send RM_buckle_switch_sts to IMM and/or IPK, do not fasten the safety belt in order to remind the central seat of arranging behind the user.When seat was not fastened the safety belt on the right of the 3rd detector 123 detected, send RR_buckle_switch_sts to IMM and/or IPK, do not fasten the safety belt in order to remind the right seat of arranging behind the user.
Can adjust back row's safety strap monitoring module.For example the quantity of detector can be adjusted into one as required, more than two or three.Though in above-mentioned embodiment of the present invention; Each seat uses a detector to detect; But also can use a detector to detect a plurality of seats simultaneously; And the quantity of seat is not limited to three, and those skilled in the art can make amendment and do not exceed scope of the present invention it.
In view of these instructions, those of ordinary skill in the art will expect other embodiments of the invention, combination and modification easily.Therefore, when combining above-mentioned explanation and accompanying drawing to read, the present invention only is defined by the claims.
