If after temperature, continuing to judge whether the second speed is greater than pre-set velocity, and when the second speed is greater than pre-set velocity, just reduce vapour
The output torque and gear of vehicle speed changer and the throttle opening of engine are in order to avoid working as automobile brake friction plate
Temperature be the output torque that automotive transmission is reduced when moment reaching preset temperature and the solar term of gear and engine
Door aperture reduces the driving experience of driver to intervene the driving of driver.It should be noted that in order to ensure driving
Safety, above-mentioned first preset time can be set to 30 seconds, it is to be understood that in the first embodiment of the present invention, not
Limit the specific value of the first preset time.
6th step obtains the third temperature of automobile brake friction plate and the third of automobile every one second preset time
Speed, and judge whether third temperature is greater than or equal to preset temperature, until judging that third temperature is less than preset temperature.
Wherein, when judging that third temperature is greater than or equal to preset temperature, the police being arranged on fascia is controlled
Show that lamp is flashed, and judge whether corresponding with third temperature third speed is greater than pre-set velocity, when with the third temperature
When corresponding third speed is greater than pre-set velocity, the output torque of automotive transmission and the solar term of gear and engine are reduced
Door aperture reduces speed to reduce the power output of engine.It should be noted that due to every one second preset time,
The third temperature of automobile brake friction plate and the third speed of automobile will be obtained, therefore, each third temperature can correspond to
One corresponding third speed.And in order to ensure driver-operated safety and comfort, above-mentioned second preset time can be with
It is set as 20 seconds or 30 seconds, it is to be understood that in the first embodiment of the present invention, do not limit the specific of the second preset time
Numerical value, that is, it can be adjusted according to actual needs.
It should be further noted that in above-mentioned 6th step, it, can in order to make last third temperature be less than preset temperature
The throttle opening of the continuous output torque for reducing automotive transmission and gear and engine can be needed, here, in order to ensure
Driver-operated safety and comfort can adjust the automotive transmission reduced every time according to the model of automotive transmission
Output torque and gear and engine throttle opening.
In the first embodiment of the present invention, pass through the first temperature and vapour according to the automobile brake friction plate got
First speed of vehicle adjusts the output torque of automotive transmission and the throttle opening of gear and engine, to reduce automobile
The temperature of speed and automotive brake is solved when automotive brake temperature is excessively high, and brake efficiency declines, if driver continues
Driving can occur braking distance and extend or the dangerous problems such as failure, reached automotive brake when the temperature is excessively high, drop
The temperature of low automobile speed and automotive brake prevents the effect caused danger because automotive brake brake efficiency declines.
