Problems solved by technology

Since the gear shifter only performs the conversion of the vehicle's driving mode according to the driver's operation, it may cause the driver to accidentally touch the gear shifter during normal driving and cause the gear to change.
For example, during normal driving, changing from a forward gear to a parking gear will cause the vehicle to slow down suddenly, which will disturb the driver's driving; what is more serious is that if the gear is changed from a forward gear to a reverse gear, Not only will it seriously damage the internal gears of the vehicle, but it may also lead to a series of dangerous situations such as loss of control of the vehicle.
Therefore, improper gear conversion is likely to cause serious driving safety accidents, threatening the safety of the driver's life and property.

Embodiment 1

[0050] figure 1 It is a flow chart of a shift control method provided by an embodiment of the present invention. Please refer to figure 1 , the specific steps of the shift control method include:

[0051] Step S10: receiving a shift signal from the electronic gear shifter.

[0052] The electronic gear shifter is controlled by the driver, and the driver toggles the electronic gear shifter to the corresponding gear position for shifting operation according to the driving needs. The difference between the electronic gear shifter and other types of gear shifters is that the electronic gear shifter controls the gear position of the vehicle through electrical signals. The electronic gear shifter has two specific buttons, one is the parking button and the other is the shift button. , and has five gears, namely Center, Up (high level), UpUp (continuous high level), Down (low level), DownDown (continuous low level), Center means that the driver has no gear shifting operation Or the...

Embodiment 2

[0086] figure 2 It is a flow chart of another shift control method provided by the embodiment of the present invention. figure 2 In steps S10-S14 and figure 1 Same, no more details here.

[0087] Such as figure 2 As shown, as a preferred implementation manner, after receiving the shift signal of the electronic gear shifter, the method further includes:

[0088] Step S20: Judging whether the shift signal is valid, if yes, then execute step S11,

[0089] Otherwise, execute step S13.

[0090] Considering that the driver accidentally touches the electronic gear shifter or some objective reasons cause the electronic gear shifter to change gears for a short time, it is judged whether the shift signal is valid, and if it is invalid, no follow-up rationalization will be carried out. The judgment of the vehicle correspondingly saves the overhead of the vehicle controller for judgment.

[0091] In addition, as a preferred implementation manner, judging whether the shift signal ...

Embodiment 3

[0107] The embodiments of the shift control method have been described in detail above, and the present invention also provides a vehicle controller. Since the embodiments of the vehicle controller correspond to the embodiments of the method part, the vehicle controller For some embodiments, please refer to the description of the embodiments in the method part, which will not be repeated here.

[0108] image 3 It is a structural diagram of a vehicle controller provided by an embodiment of the present invention. The vehicle controller provided by the embodiment of the present invention specifically includes:

[0109] The gear shifter signal receiving module 10 is used for receiving the shift signal of the electronic gear shifter.

[0110]The required gear analysis module 11 is used to determine the required gear of the electronic gear shifter according to the current vehicle state, the current executed gear and the shift signal.

[0111] The gear judging module 12 is used t...

Abstract

The invention discloses a gear-shifting control method and a vehicle control unit. The method includes the steps that a gear-shifting signal of an electronic gear device is obtained; according to thecurrent vehicle state, the current executed gear and the gear-shifting signal, the required gear of the electronic gear device is determined; whether the required gear is identical to the executed gear or not is judged; if the required gear is identical to the executed gear, a vehicle is controlled to keep the executed gear; and if the required gear is not identical to the executed gear, the vehicle is controlled to execute the required gear. By the adoption of the provided method, when the gear of the gear device is changed, the vehicle control unit judges whether the change is reasonable ornot, and corresponding operation is conducted according to a result. Therefore, by the adoption of the method, the situation that the gear is shifted due to mistaken operation conducted by a driver tothe gear device is reduced, and vehicle gear-shifting reliability and vehicle traveling safety are improved. In addition, the vehicle control unit has the above effects similarly.

Description

technical field [0001] The invention relates to the field of vehicle control, in particular to a gear shift control method and a vehicle controller. Background technique [0002] With the improvement of national living standards, cars have changed from a luxury item to a common means of transportation for household or business use. In the era when the automobile industry is relatively developed, people's requirements for automobiles are no longer limited to usability, and more and more attention has been paid to the driving safety of vehicles. [0003] As we all know, the gear shifter is a device used to control the different driving gears of the vehicle. The vehicle performs the conversion of the corresponding driving mode according to the driver's operation on the gear shifter, such as forward, backward, parking, etc. Since the gear shifter only executes the conversion of the driving mode of the vehicle according to the driver's operation, it may cause the driver to accid...
