The specific embodiment
The automobile upward slope start assistance method of present embodiment as shown in Figure 1, mainly may further comprise the steps:
100, gather the step of the current gradient;
200, the gradient obtained the step of cooresponding engine speed before utilization was deserved;
300, according to the step of this motor speed control throttle opening.
The present invention is the gradient of utilizing the weight sensor detection vehicle to be in, by the gradient signal of gathering, regulate engine speed and improve vehicle traction power, improved safety, avoided mechanical breakdown taking place and causing bigger safety misadventure, the while can help driver's hill start easily by actv..
Below use preferred forms as shown in Figure 2 that described automobile upward slope start assistance method is further detailed:
110, perception current vehicle speed,
If 120 current vehicle speed are lower than when starting threshold value, execution in step 100;
When 130, current vehicle speed is higher than outage threshold, stop step 100.
200, the step of utilizing the current gradient to obtain the cooresponding engine speed of this gradient comprises;
210, climb up this required tractive force in gradient slope by described current grade computations automobile;
220, detect power-transfer clutch, when testing result is a power-transfer clutch when lifting, execution in step 230;
230, the described step that this tractive force is converted to engine speed.
Certainly the step of utilizing the current gradient to obtain the cooresponding engine speed of this gradient can also be obtained by the mode of tabling look-up.
300, according to this motor speed control throttle opening.
Adopt the householder method of this preferred forms, the driver closes as long as gently be lifted away from, slowly get off the brakes, need not is increasing just light hill start of throttle, avoid aforementioned in a rush situation to occur and the mode generation mechanical breakdown of other auxiliary brakings and cause bigger safety misadventure, can help driver's hill start easily by actv. simultaneously.
A kind of automobile upward slope starting ancillary system also is provided, as shown in Figure 3 and Figure 4, mainly comprises: weight sensor, computing module, throttle-valve control module.Weight sensor is gathered the current gradient; The gradient obtained cooresponding engine speed before the computing module utilization was deserved; The throttle-valve control module is according to the aperture of this motor speed control throttle gate.
Increase car speed sensor, start unit, stop element as another embodiment on the basis of a last embodiment, car speed sensor is in order to the perception current vehicle speed; Start unit is when described current vehicle speed is lower than the startup threshold value, triggers described computing module and receives data from described weight sensor; Stop element is when described current vehicle speed is higher than the startup threshold value, disconnects described computing module and described weight sensor.Start unit, stop element are integrated in the supplementary module.
Preferred forms is divided into tractive force unit and rotating speed unit with the computing module in the aforementioned embodiments, and has increased power-transfer clutch probe unit and clutch switch.The described current grade computations automobile of tractive force unit by using is climbed up this required tractive force in gradient slope; The rotating speed unit is converted to engine speed with this tractive force.(computing module can also be realized computing function with the form of tabling look-up certainly, and the corresponding setting lookup unit gets final product on its hardware.) the tractive force unit can be integrated in the supplementary module, the rotating speed unit is integrated in the engine controller.The power-transfer clutch probe unit is used to detect power-transfer clutch; Clutch switch is that the testing result at the power-transfer clutch probe unit is a power-transfer clutch when lifting, and triggers described tractive force unit and described rotating speed unit carries out communication.
Above-mentioned automobile upward slope starting ancillary system has the following advantages: improve the intelligent of automobile, rev up is similar to the automatic guidance throttle automatically; In a rush accident-prone probability when reducing hill start; Be easy to realize that only needing increases a sensor or increase a controller again, in conjunction with Fig. 3, change software can be realized function.
Specific operation process is as follows: shown in Fig. 3 and 4, car key is given electricity at ON, and supplementary module is started working, and transmits vehicle speed signal by car speed sensor and gives supplementary module, and when the speed of a motor vehicle was lower than 5km/h, start unit started supplementary module and starts working.Wherein the signal of the speed of a motor vehicle is taked, and can directly derive from the CAN network signal of ABS system by collection; Also can directly take from the average speed indicator signal of instrument.
When supplementary module is started working, gather automobile gradient of slope of living in from weight sensor, angle-data by weight sensor, how many antagonistic forces that is caused that is calculated the automobile gravity that is caused by this gradient by supplementary module in-to-in tractive force unit is (because on the slope, the downward friction force of automobile is than little on the level road, therefore this resistance can not considered), how many tractive forces that calculates required upslope again needs.
When the power-transfer clutch probe unit detects power-transfer clutch and lifts, clutch switch then notifies supplementary module to begin to give engine controller with the result transmission of aforementioned calculation, rotating speed unit in the engine controller is by the needed engine speed of data computation, send the aperture of signal control throttle gate then to the throttle-valve control module, thereby the raising engine speed increases vehicle traction power.
When car speed was higher than 5km/h, stop element then stopped supplementary module, and supplementary module notice engine controller rotating speed will recover normally, and can improve rotating speed this moment by driver's step on the accelerator.Common engine control module and throttle-valve control module all are integrated in ECU (Electronic Control Unit, electronic control unit) on, in addition, start unit, stop element, tractive force unit, rotating speed unit (being supplementary module and engine controller) all are integrated in the controller, can reach the purpose that reduces arrangement space.
