All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The following describes embodiments of the present application in a specific context, and in the following, describes a hybrid vehicle.
The first embodiment is as follows:
the embodiment of the application provides a gear shifting control device of a vehicle, which is specifically described below with reference to the accompanying drawings.
Referring to fig. 1, a schematic diagram of a gear shifting control device of a vehicle according to an embodiment of the present application is shown.
The shift control apparatus of a vehicle includes: a vehicle control unit 101 and a shift control unit 102; the gear shifting control unit 102 is configured to send a gear shifting position signal to the vehicle control unit 101; the vehicle control unit 101 is configured to send a shift prohibition instruction to the shift control unit 102 when it is determined that the shift position signal is invalid and the vehicle speed of the vehicle is lower than a preset value; the shift control unit 102 is configured to prohibit a shift action when receiving the shift prohibition instruction.
As an optional implementation manner, the shift control unit 102 may send the shift position signal to the vehicle controller 101 every preset period, and the shift control unit 102 may also send the shift position signal to the vehicle controller 101 in real time.
It is understood that the preset period may be 1s, 0.5s, 0.1s or 0.01s, and those skilled in the art can determine the value of the preset period according to actual needs of specific situations. The shift position signal may be a signal for indicating a driver's intention to shift, and may be represented by a position of a shift lever, and the shift control unit 102 may acquire position information of the shift lever through a sensor, and then generate the shift position signal.
As an optional implementation manner, the vehicle control unit 101 may first determine that the shift position signal is invalid, and then determine that the vehicle speed of the vehicle is lower than a preset value, and send a shift prohibition instruction to the shift control unit 102; after confirming that the shift position signal is invalid, and when the vehicle speed is greater than a preset value, the vehicle control unit 101 will not send a shift prohibition instruction to the shift control unit 102.
As an optional implementation manner, when it is determined that the vehicle speed of the vehicle is lower than a preset value, and it is determined that the shift position signal is invalid, the vehicle controller 101 may send a shift prohibition instruction to the shift control unit 102; when the vehicle speed of the vehicle is determined to be lower than the preset value and the shift position signal is normal, the vehicle control unit 101 will not send a shift prohibition instruction to the shift control unit 102.
It can be understood that the vehicle control unit 101 will send a shift prohibition instruction to the shift control unit 102 only when the shift position signal is invalid and the vehicle speed of the vehicle is lower than a preset value; the preset value can be 20km/h or 10km/h, and a person skilled in the art can determine the preset value according to actual needs; the vehicle controller 101 may prohibit torque output to respond to an accelerator, and control low-speed driving of the vehicle through a brake pedal without performing a power-off operation on the vehicle.
It can be understood that when the vehicle is in a low-speed driving state, and the vehicle controller 101 detects that the shift position signal sent by the shift control unit 102 is invalid, a shift prohibition instruction is sent to the shift control unit 102, so that the driver is prohibited from switching the gears, the vehicle controller 101 is prevented from mistakenly recognizing the driver's shift intention, and the vehicle controller is not required to power off. Instead of the prior art, the whole vehicle is powered off, and after the vehicle is powered off, the whole vehicle controller cannot respond to the gear shifting operation even if the vehicle is shifted, so that the phenomenon that the whole vehicle controller mistakenly identifies the gear shifting intention of a driver is avoided.

As an alternative embodiment, the shift control unit 102 may immediately prohibit a shift action upon receiving the shift prohibition instruction; the shift control unit 102 may further prohibit a shift action after a preset time when receiving the shift prohibition instruction.
It is understood that the shift prohibition instruction may be for locking the position of the shift lever, so that the driver cannot switch the shift position through the shift lever, thereby avoiding the vehicle controller 101 from erroneously recognizing the driver's shift intention.
The vehicle control unit can be a vehicle control unit HCU of the hybrid electric vehicle, and the gear-shifting control unit can be a gear-shifting control unit SCU of the hybrid electric vehicle; the human-computer interaction unit can be an intelligent instrument unit FICM of a hybrid electric vehicle.

Therefore, when the gear shifting position signal is invalid, the gear shifting action is forbidden, so that the operation of gear shifting of a driver is forbidden, the torque output is forbidden to respond to an accelerator, the brake pedal controls the whole vehicle to run at low speed, the vehicle does not need to be powered off, the problem that the whole vehicle controller mistakenly identifies the gear shifting intention of the driver is avoided, the problem that the driver is scared due to the fact that the vehicle loses power is avoided, and the traffic accident occurrence rate is reduced.

It is understood that when the shift position signal is still disabled but the vehicle speed of the vehicle is greater than the preset value, the vehicle controller 201 may send a shift permission command to the shift control unit 202.
As an optional implementation manner, after the shift position signal returns to normal, the vehicle controller determines 201 whether the gear selected by the user and sent by the human-computer interaction unit 203 is consistent with a gear carried in the shift position signal sent by the shift controller 202; and if the gear is inconsistent, performing gear shifting action by using the gear selected by the user.
