The specific embodiment
For the purpose, technical scheme and the advantage that make the embodiment of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
The term that uses in the present invention in order to embodiment to be described, is not only to limit the invention.Singulative in this specification sheets does not have to comprise plural form under the prerequisite of special suggestion in sentence yet." the comprising (comprises) " of using in specification sheets or " (comprising) that comprise " do not get rid of the existence of more than one other member, step, action and/or element beyond related member, step, action and/or element or replenish.With reference to the accompanying drawings, the embodiment of the present invention is described in detail.
Fig. 2 is the intelligent servo-unit starter gear 200 of the embodiment of the present invention.
With reference to Fig. 2, the intelligent servo-unit starter gear 200 of the embodiment of the present invention comprises battery section 240, voltage rectifier 210 and microcomputer 220.
The vehicle outbound also starts rear voltage rectifier 210 from OUT terminal 214 and RST_OUT terminal 216 output VCC and reset signals first.Microcomputer 220 is to receive the input of VCC and reset signal and enter normal mode after initialization and output keeps delay-Gao (Holdup-high) signal of voltage rectifier 210 actions.
After this in vehicle operating process, the flame-out microcomputer 220 of vehicle can enter the economize on electricity monitoring pattern that only has delay (Holdup) signal output terminal 222 and energizing signal input terminal 224 to keep state of activation.Voltage rectifier 210 is still to keep normal operating condition according to delay-Gao (Holdup-high) signal from microcomputer 220 inputs after vehicle is flame-out.
Be described as follows.When starting first after the vehicle outbound, INH terminal 212 is transfused to delay-Gao (Holdup-high) signal by the SENSE_IG signal, initial conditions when after voltage rectifier 210 output VCC and reset signal, microcomputer receives VCC and reset signal and is initialized to outbound subsequently and enter normal mode is from GPIO terminal 222 output delaies-Gao (Holdup-high) signal.Voltage rectifier 210 entered and did not know that incoming signal is high or low fixing (Floating) state this moment, but therefore diode (D2) 252 and diode (D3) 221 difference independent actions there is no impact to mutual signal.Consequently, the INH terminal 212 of voltage rectifier 210 is transfused to height all the time.Microcomputer 220 is whether to keep appropriate voltage by AD channel monitoring SENSE_IG 254.
If after vehicle is flame-out, SENSE_IG 254 values are less than defined critical value by microcomputer 220 identification vehicle flameout states.Diode (D2) although 252 are low voltage but diode (D2) 252 and diode (D3) 221 independent actions respectively, therefore mutual signal be there is no impact.220 transmission lag-Gao of microcomputer (Holdup-high) signal, the INH terminal 212 of voltage rectifier 210 are to continue to keep high state.And the voltage rectifier 210 normal operations of meeting continuation, vehicle and state of the system are stored into external memory storage.This moment, microcomputer 220 was not to cut out (OFF) system but enter only to consume minimum electric power and only have delay (Holdup) signal output terminal and the economize on electricity monitoring pattern of energizing signal input terminal maintenance state of activation.
In other words, even vehicle is flame-out, but voltage rectifier 210 normally move, and whether 220 of microcomputers enter the input of economizing on electricity monitoring pattern and monitoring energizing signal.Under the state that vehicle stops working, after the signal that opens and closes signal 280 or operator's saddle load cell 290 from braking-lamp (brake-light) output signal 260, door was imported into energizing signal input terminal 224 as energizing signal, microcomputer can activate braking-angle (brake-angle) signal input terminal 223 and AD converter terminal 225.Microcomputer 220 is to receive braking-angle (brake-angle) signal 270 by braking-angle (brake-angle) signal input terminal 223.
Fig. 3 is the precedence diagram of intelligent servo-unit starting method.
With reference to Fig. 3, under the state that vehicle stops working, 220 of microcomputers consume minimum electric power, enter the economize on electricity monitoring pattern (step S310) that only has delay (Holdup) signal input terminal 222 and energizing signal input terminal 224 to be in state of activation.
Energizing signal is imported into microcomputer (step S320) thereupon
Braking-angle (brake-angle) signal input terminal 223 be activated (step S330) thereupon.
Braking-angle (brake-angle) signal input value is greater than critical value, microcomputer 220 can enter normal mode, activate intelligent servo-unit brake system 230(step S350), if braking-angle (brake-angle) signal input value is less than critical value, microcomputer 220 reenters economize on electricity monitoring pattern (step S310).
After being triggered, microcomputer 220 confirms that braking-angle (brake-angle) signal input value is in order accurately to judge whether the driver steps on brake pedal really.
Fig. 4 is the constructional drawing of successive comparison type AD converter of the intelligent servo-unit starting method of the embodiment of the present invention.
When braking-angle (brake-angle) signal is imported into braking-angle (brake-angle) signal input terminal 223, AD converter will brake-and angle (brake-angle) signal converts digital signal to.AD converter has Quick-type AD converter, successive comparison type AD converter, biproduct somatotype AD converter, trigonometric integral type AD converter etc., and the present invention uses successive comparison type AD converter.
Successive comparison type AD converter 400 is that SAR (Successive Approximation Register) is combined from most significant bit successively to the SAR computing of low bit correction, implements analog-digital conversion.Successive comparison type AD converter 400 is to make at short notice the output of DA conv 430 be similar to and shorten the analog-digital conversion time and realize simply circuit to the analog input impedance.
In Fig. 4, the successive comparison type AD converter of the intelligent servo-unit starting method of the embodiment of the present invention comprises analog input section 410, reference voltage input part 420, DA conv section 430, comparing section 440, SAR operational part 450 and digital efferent 460.
Specifically, the voltage of braking-angle (brake-angle) signal is input to analog input section 410.Predefined digitalisation reference voltage is input to reference voltage input part 420.DA conv section 430 converts predefined digitalisation reference voltage to aanalogvoltage.Comparing section 440 is to compare to the input voltage of analog input section 410 with at the aanalogvoltage of DA conv section 430 conversions.SAR operational part 450 is that the SAR computing is implemented in the output that receives comparing section 440.The operation result of numeral efferent 460 output SAR when the SAR computing arrives lowest order.
Fig. 5 is the algorithm precedence diagram of the successive comparison type AD converter of intelligent servo-unit starting method.
With reference to Fig. 5, under the flame-out state of vehicle, the driver steps on brake and simulating brake-angle (brake-angle) when signal input terminal is activated,
First input the voltage (step S510) of simulating brake-angle (brake-angle) signal.
Then reference voltage is input to DA conv 430(step S520).
Then the voltage of 440 pairs of simulating brake-angles of comparing section (brake-angle) signal and reference voltage compare rear output digit signals (step S530).
Then SAR operational part 450 carries out computing (step S540) from most significant bit to low level.
(step S550) output digit signals (step S560) when then SAR operational part 450 arrives lowest order,
If SAR operational part 450 is not lowest order, digital signal is inputted DA conv section 430 and repeatedly implemented said process (step S520).
