Described sensor comprises accelerator pedal sensor and brake pedal sensor, described accelerator pedal sensor will speed up that pedal 7 (as shown in Figure 1) is changed by the angle of being trampled and the signal of angular acceleration is transferred to described central control unit S, described central control unit S analyzes driver requested travelling speed and acceleration, and then by control engine throttle door controller 8, control the aperture of engine air throttle, and 3 pairs of speed changers of control speed-changer executing mechanism 2 are implemented the gearshift action.Described engine throttle door controller 8 comprises motor and worm-and-wheel gear, described worm-and-wheel gear links to each other with described engine air throttle, described motor drives described engine air throttle motion by worm-and-wheel gear, and promptly described central control unit S controls the aperture of described engine air throttle by controlling described motor.Wherein, described motor can be stepper motor.
Slowly step on 5%～75% angle when the driver will speed up pedal 7, central control unit S controls the running of motor and speed changer under economic model with acceleration stably.In other words, this moment, automobile speed was directly proportional with the angle of driver's stepping on accelerator pedal 7.
When the driver will speed up pedal 7 when stepping on 75%～100% angle, automobile can increase the output of power to improve automobile speed always, and when the angle of driver person's stepping on accelerator pedal reached 100%, central control unit S improved the speed of a motor vehicle with maximum acceleration.In other words, driver's bend the throttle is during greater than 75% angle, even the driver keeps accelerator pedal position constant, central control unit also can make car speed constantly increase.Increasing speed is directly proportional with the position of accelerator pedal in 75%～100% interval.
In addition as shown in figure 13, speedometer 10 of the present invention also comprises an indication pointer 11, this indication pointer 11 shows is that driver's bend the throttle 7 or brake petal 9 are wished the speed of a motor vehicle that reaches, and central control unit S simultaneously can be according to the indication pointer 11 of this speedometer 10 of SC sigmal control of accelerator pedal sensor or brake pedal sensor transmission.When accelerator pedal in 75%～100% position, when the indication pointer indicated speed of a motor vehicle reaches the required speed of a motor vehicle of driver, driver (for example angular velocity varies is greater than 20%/S) immediately lifts accelerator pedal to certain position, this position is the required speed of a motor vehicle of corresponding driver, as improving automobile speed again, continue to step on accelerator pedal 7 and get final product, otherwise lift accelerator pedal 7.
When the driver lifted accelerator pedal 0%～5% angle, central control unit S can reduce the speed of a motor vehicle by certain acceleration, up to idling; When accelerator pedal 7 during in 0%～5% angle, central control unit S receives brake pedal sensor the signal input, then can reduce the speed of a motor vehicle with bigger acceleration (negative acceleration).
Under the prerequisite that does not have to change when the gear of speed changer, accelerator pedal 7 positions and the proportional setting of throttle position, but if the gear of speed changer changes, accelerator pedal 7 positions and throttle position are then proportional not to the utmost, for example, and when accelerator pedal 7 steps down in 37% angular orientation, closure opens 66%, when the accelerator pedal aperture was increased to 59% angle, throttle opening may be in 50% position, because this moment, speed changer increased a gear.
The signal that the angle that described brake pedal sensor is trampled brake petal 9 changes is transferred to described central control unit S, described central control unit S receives brake petal less than the described motor fuel cut-off of 5% SC sigmal control, reduce engine power, increase transmission resistance, if brake petal is greater than 5%, then control motor and recover the fuel feeding normal operation, control speed change gear simultaneously and hang, interrupt the power of motor and power train into neutral.
The following describes control procedure of the present invention:
As shown in figure 14, its demonstration is the flow chart of vehicle starting.Engine idling operation under the vehicle stationary state, then the driver steps on brake petal, hangs forward gear (D retaining); Central control unit S receives the starting instruction, and the separation of control starting device, and the control speed-changer executing mechanism is hung into a retaining speed changer; The driver loosens the brake gradually afterwards, and the power of starting device transmission reduces and increases with braking force, and the aperture of closure constantly increases simultaneously; When the driven member of starting device reached certain rotating speed, engine speed can reduce moment, made the same rotating speed of starting device principal and subordinate's moving part, the lockable mechanism locking, and principal and subordinate's moving part rigidity connects; Engine speed raises gradually, and moment increases, and automobile slowly moves ahead, and automobile is finished starting.
As shown in figure 15, its demonstration is the flow chart of motor car engine idle running.After engine start is finished, the driver does not step on accelerator pedal, central control unit is received the idling instruction, and whether the moving water water temperature of analysis engine cold reaches normal temperature (85 ℃-95 ℃): when its water temperature does not reach normal temperature, motor is then by normal idle running, when its water temperature reached normal temperature, motor was then by the economic model idle running.Described economic model is meant that transmission system need not engine power, and motor carries out interrupted oil supply to cylinder, and the reduction valve of fuel feeding cylinder is not opened, and reduces resistance, to reach energy-conservation purpose.
As shown in figure 16, its demonstration is the flow chart that the motor of automobile is finished starting.Ignition switch 12 has closes, connects, lights a fire and start four gears.Manually ignition switch is forwarded to " connection " retaining; Central control unit begins initialization; The power supply of central controller controls electric equipment, control ignition switch ignition, starting simultaneously, when ignition switch forwarded " starting " retaining to, the central controller controls reduction valve was opened, and connected starter circuit capable, closed other consumer; Then when bent axle reaches certain rotating speed, through central controller controls, commencement of fuel injection, reduction valve cuts out simultaneously, starter circuit capable disconnects, and recovers other consumer, ignition switch playback " igniting " keep off normal ignition, engine start is finished.
As shown in figure 17, its demonstration is car deceleration (the negative acceleration) process flow diagram flow chart.When the indication speed of a motor vehicle of indication pointer during less than actual vehicle speed, central control unit is received deceleration instruction, then controls throttle controller and reduces throttle opening, afterwards fuel cut-off, igniting; Analyze actual vehicle speed and whether reach the indication speed of a motor vehicle: when actual vehicle speed reaches the indication speed of a motor vehicle, under the control of central control unit, recover fuel feeding, igniting, and select the economic model running; When actual vehicle speed does not reach the indication speed of a motor vehicle, under the control of central control unit, recover fuel feeding, igniting, speed changer is hung into neutral (N retaining) afterwards, and open the engine reduces transmission gear, continue fuel cut-off, igniting afterwards, reach the indication speed of a motor vehicle until actual vehicle speed.
For example, the existing speed of a motor vehicle is 69km/h, and it is 20km/h that the driver specifies the speed of a motor vehicle.
These car engine two retaining economical consumption of fuel rotary speed areas are: 1700～2300r/min.Rotating speed is now: 2970r/min.
Each gear velocity ratio of speed changer is: i1=3.545, i2=2.105, i3=1.429, i4=1.029, i5=0.838, ir=3.50
Base ratio is: 4.87 diameter of tyres are: 0.62m.
System's control situation is as follows: when the driver depressed brake petal, control ignition system of system, oil supply system quit work, and throttle opening is transferred to minimum, utilize engine braking in the time of braking, increased the negative acceleration of automobile; When the speed of a motor vehicle was reduced to 20.5km/h, system controlled each cylinder reduction valve and closes, and the igniting oil supply system recovers normal, and motor begins self running, finishes negative accelerating process.The central controller controls speed-changer executing mechanism is hung into neutral, regulates engine speed to 1750r/min, and the control speed-changer executing mechanism is hung into second gear the held stationary speed of a motor vehicle.
The braking and the present engine braking of control motor are completely different in system, in the time of present engine braking, ignition system and oil supply system are still in work (increase oil consumption), braking effect is bad again simultaneously, and the engine braking that utilizes in the system is braking under the real meaning, has improved the effect of braking in the time of energy saving.Last example is that the driver steps on the situation that braking is stepped on, if the indication speed of a motor vehicle and the very little negative acceleration of actual vehicle speed difference, the driver can not step on braking fully and step on, and only utilizes self braking of motor can finish fully.
The method that central control unit S of the present invention reduces the speed of a motor vehicle has: (1) fuel cut-off, do not open reduction valve; (2) fuel cut-off is opened reduction valve; (3) individual cylinder fuel feeding is not opened reduction valve.
As shown in figure 18, its demonstration is automobile accelerating process flow chart.When the indication speed of a motor vehicle of indication pointer during greater than actual vehicle speed, central control unit is received assisted instruction, then control open the engine, whether analyze the accelerator pedal angular acceleration afterwards less than setting value, if angular acceleration is during less than setting value, described central controller controls motor economic model running; If angular acceleration is during greater than setting value, described central controller controls motor turns round with dynamic mode.The central control unit open the engine, improve engine speed, thereby the raising automobile speed, if when engine speed reaches higher rotation speed, actual vehicle speed is still less than the indication speed of a motor vehicle, central control unit instruction speed change gear is hung into neutral, fuel cut-off, when engine speed dropped to than the slow-speed of revolution, the central controller controls speed change gear was hung into a high gear, open the engine judges whether present actual vehicle speed reaches the indication speed of a motor vehicle.
For example, the existing speed of a motor vehicle is 20km/h, and it is 69km/h that the driver specifies the speed of a motor vehicle.
These car engine four retaining economical consumption of fuel rotary speed areas are: 2100～3200r/min.Rotating speed is now: 1761r/min, two retainings.
Each gear velocity ratio of speed changer is: i1=3.545, i2=2.105, i3=1.429, i4=1.029, i5=0.838, ir=3.50
Base ratio is: 4.87 diameter of tyres are: 0.62m.
Central control unit S control situation is as follows: central control unit S control (strengthening gradually) throttle opening, improve engine speed; When engine speed is brought up to 2500 commentaries on classics (speed of a motor vehicle is 28.5km/h), system's control speed-changer executing mechanism is removed (extension neutral) with two retainings, and each oil supply cylinder of instantaneous interruption, when the rotating speed of motor is reduced to 1670r/min, the order speed-changer executing mechanism is hung into three retainings, and open the engine, make the rotating speed of motor continue to raise, repeat above-mentioned circulation, remove three retainings constantly at motor 2000r/min, when 1800 change, hang into four retainings, and open up the engine, the speed of a motor vehicle is 69km/h when improving engine speed to the 2970r/min left and right sides.
