Door and cause power to reduce, ensure the security of running car.
Brief description of the drawings
Fig. 1 is the module diagram of the present invention.
Embodiment
Referring to the drawings, further describe the present invention concrete technical scheme, in order to those skilled in the art into
Understand the present invention to one step, the limitation without forming its power；
Embodiment 1, with reference to Fig. 1, a kind of electric automobile uphill starting device, including angular transducer and throttle are described
The input terminal of the output terminal data connection entire car controller of angular transducer and throttle, the entire car controller include computer
Module, angle moment of torsion A, throttle moment of torsion B, comparison module, the fan-out of the computer module is according to connection angle moment of torsion A, oil
The input terminal of door moment of torsion B, the angle moment of torsion A, throttle moment of torsion B output terminal data connection comparison module input terminal, the angle
Spend moment of torsion A fan-outs and exported according to angled moment of torsion A is connected, throttle moment of torsion B fan-outs are defeated according to throttle moment of torsion B is connected with
Go out.
Embodiment 2, in a kind of electric automobile uphill starting device and method described in embodiment 1, comprises the following steps,
(1) during uphill starting, under the action of same torque, power F is the same, when a=0 ° of angle of inclination, vehicle
Controller is controlled to the torque output of motor 10%；
(2) when a=5 ° of angle of inclination, entire car controller is controlled to the torque output of motor 15%, when a=10 ° of angle of inclination
When, entire car controller is controlled to the torque output of motor 20% etc.；
(3) entire car controller according to angular transducer outflow come angle of inclination a, calculate required moment of torsion A at that time；According to
The throttle percentage that throttle receives, calculated torque B；
(4) during uphill starting, entire car controller can freely change torque value according to the angle value of angular transducer, rightly
Adjust electric energy.
Embodiment 3, in a kind of electric automobile uphill starting method described in embodiment 1 or 2：Electric automobile starting-up process
In, when hanging forward, entire car controller can actively export even twisting moment control driving motor climbing.In uphill starting process
In, under the action of same torque, power F is the same, but the value of angle a is bigger, and automobile overcomes the value of self gravitation with regard to big,
The power of direction of advance is with regard to small, so as to cause automobile speed-raising difference.Angle a meets hour, and speed-raising is fast, but power consumption；Angle a meets
When big, speed-raising is slow, and driver needs to export come high torque by stepping on the gas again, meets that speed-raising requires.In starting-up process, such as
Fruit detects the angle a in each ramp using angular transducer, and according to different angle a, entire car controller flexibly calculates often
Required torque value under a ramp, such as：When a=0 ° of angle, entire car controller is controlled to the torque output of motor 10%, works as angle
During a=5 ° of degree, entire car controller is controlled to the torque output of motor 15%, and when a=10 ° of angle, entire car controller is to motor
20% torque output control etc..According to different ramps, the torque output of vehicle control unit controls is different, causes vehicle to be realized
Speed-increasing effect it is equal, comfort and security when being so conducive to vehicle starting, also so that energy consumption is evenly distributed, play section
The effect of energy, emphasis realize intelligence starting function；
During uphill starting, driver would generally be intended to step on the gas to control running car according to oneself.Under normal circumstances, driver
More than 80% throttle is understood to climb, and during with car, then can gently be stepped on the gas, and can be caused if throttle kicks the beam at this time
Power reduces.It is this in order to solve the problems, such as, entire car controller by calculating corresponding torque and after comparison, according to
Lower strategy carries out torque output；
Entire car controller according to angular transducer outflow come angle a, calculate required moment of torsion A at that time；Connect according to throttle
Received throttle percentage, calculated torque B.When driver steps on the gas it is bigger when, if B>A, i.e. throttle output torque are more than
The even twisting moment calculated according to angle a, then entire car controller according to driver intention come output torque；
On the contrary, when driver gently steps on the gas, the even twisting moment calculated at this time according to angle a is bigger, and at this time in order not to
Allow power to reduce, ignore driver and gently step on the gas exported moment of torsion, allow automobile to keep original state traveling.
