Abstract
The invention discloses a method for automobile safe start, especially the method for safe start of automobile with AMT. a neutral switch is added on the shifting mechanism of automobile with AMT while a switch controlled by MCU is added on the firing circuit. MCU controls controlling switch on by neutral switch signal, brake switch signal and position sensor signal of clutch. The switch is controlled off when the key is on the one shift signal or no-speed signal of engine. Furthermore whether driver can start with ignition is controlled. The invention can solve judgment mistake of potentiometer shifting sensor, the phenomenon that accident occurs easily when it is started and stopped, and improve start safety of AMT automobile.
Description
Technical field:
The present invention relates to the start-up control method of AMT (electric control mechanical type automatic speed variator) vehicle, especially improve the controlling method of the Security of vehicle launch.
Background technique:
Domestic AMT automobile gear level position all is to be judged by the voltage swing that is installed in the potentiometer in the fork shift mechanism at present, because environment, the multiple reasons such as reliability of potentiometer itself, the voltage of output can have discrepancy with the magnitude of voltage of actual-gear, cause the gear misjudgment, this is very big to AMT vehicle launch Safety Effect, if the vehicle actual-gear is at one grade, and gear position sensor is judged as neutral gear, at this moment driver's ignition trigger may cause the mistake starting, be that vehicle can be rushed out forward suddenly, can have an accident easily.
Summary of the invention:
The objective of the invention is at above-mentioned problems of the prior art, solve the potentiometer gear position sensor, a kind of safety starting control method for vehicle is provided, increase the Security of AMT vehicle launch as if the phenomenon that error in judgement, the startup of stopping are prone to accidents.
For this reason, the present invention proposes a kind of safety starting control method for vehicle, it is characterized in that comprising the following steps: (1) sampling neutral position switch signal, brake switch signal, clutch position switching signal; (2) signal that samples according to step (1) judge whether neutral gear and whether step on brake and clutch whether from the position; (3) if the result who judges in the step (2) for not, then returns step (1);
(4) if the result who judges in the step (2) is for being then to allow ignition trigger.
Wherein:
The neutral switch signal of being sampled in the step (1) is from switch type neutral gear sensor.
The brake switch signal of being sampled in the step (1) is from brake sensor.
The clutch position switching signal of being sampled in the step (1) is from clutch position sensor.
Allowing ignition trigger in step (4) is to realize by a switch by MCU control.
Adopt the beneficial effect of above scheme: because sampling neutral position switch signal, this be of increasing newly with fork shift mechanism on the parallel device of potentiometer, thereby whether can judge vehicle more accurately at neutral state, thereby avoid mistake to start to walk.Adopt above scheme only to need to install a neutral switch additional near the shifting cam of AMT, installing one in firing circuit additional has the switch of MCU control to get final product, and little to the change of former mechanism, method is simple and convenient, easily implements.
Description of drawings:
Fig. 1 is the hardware chart of embodiment of the invention safety starting control method for vehicle.
Fig. 2 is the software flow schematic representation of safety starting control method for vehicle of the present invention.
Embodiment
Also in conjunction with the accompanying drawings the utility model is described in further detail below by embodiment.
The present invention needs switch type neutral sensor, and clutch position sensor installs a MCU control switch etc. additional in brake sensor and the conventional point ignition circuit.Then by specific program control, analysis.
As shown in Figure 1, increase is equipped with AMT vehicle launch security arrangement and is mainly comprised a single-chip microcomputer (MC9S12D64), switch type neutral sensor, and clutch position sensor installs a MCU control switch etc. additional in brake sensor and the conventional point ignition circuit.PB1, PB2 are respectively brake sign and igniting sign.When connecing, the PB1 port is masked as zero when high.Promptly do not touch on the brake and be masked as one, touching on the brake is masked as zero.When connecing, the PB2 port is masked as zero when high.I.e. igniting is masked as one when closing.PB3 is the neutral position switch signal.PB1, PB2, PB3 all will strengthen signal through integrator IC13.AD0 is the clutch position sensor signal.AD0 receives on the single-chip microcomputer as AD converted input signal through mu balanced circuit output ACH0.DC-DC this part is that a direct current regulation circuit is promptly imported the DC voltage-stabilizing of 12V through integrated regulator output 5V.The neutral position switch signal that collects, the brake switch signal, the clutch position sensor signal is read by program.Whether they are used for controlling the top right plot switch and connect.When step on the brake and on neutral and clutch from the position just can start.
As shown in Figure 2, when MCU (mechanical control unit) collects the neutral signal that the switch type sensor sends, the clutch signal that clutch position sensor sends, the brake signal that brake switch sends, if three conditions all satisfy, then close by relay control switch, at this moment, but driver's ignition trigger.If above-mentioned three conditions have one not satisfy, then MCU does not make firing circuit connect, and this moment, the driver can't ignition trigger.If key is beaten when one grade or motor do not have rotating speed, then MCU disconnects firing circuit by relay control switch.
