Detailed Description
In addition, the embodiments of the present invention and the features of the embodiments may be combined with each other without conflict.
The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
Fig. 1 is a flowchart of a vehicle gear shifting method according to an embodiment of the present invention. As shown in fig. 1, the vehicle includes a first shift input device and a second shift input device that provide signals for shifting and upshifting gears, the method comprising:
step S11, detecting the current gear of the vehicle;
for example, the current gear of the vehicle may be a forward gear (D), a reverse gear (R), a neutral gear (N), a parking gear (P), a manual gear (M), and the like.
And S12, controlling the gear of the vehicle to be switched from the current gear to a target gear according to the received signal of the first gear shifting input device and/or the signal of the second gear shifting input device and the auxiliary signal of the vehicle based on the detected current gear.
For example, since the current gear of the vehicle may be forward (D), reverse (R), neutral (N), park (P) or manual (M), the Transmission Control Unit (TCU) controls the gear to be switched to a different target gear for a different current gear and for the received signal of the first and/or second shift input device, plus the auxiliary signal of the vehicle. It is understood that the target gear may also be a forward gear, a reverse gear, a neutral gear, a parking gear, or a manual gear, and may also be a gear with different torques such as a first gear and a second gear in the manual gear. And the assist signal may be at least one of a signal of pressing a brake pedal of a vehicle, a signal of an electronic parking brake of the vehicle, a signal of a vehicle speed, and a signal of a moving direction of the vehicle. The first and second shift input devices may be in the form of a paddle or a button, and are not limited herein.
Fig. 2 is a schematic diagram of a communication structure according to an embodiment of the present invention. As shown in fig. 2, a signal of a Brake pedal (Brake, br) is transmitted to an Engine Control unit (ECM), and then transmitted to the TCU through a CAN bus; a signal of an Electronic Parking Brake (EPB) is transmitted to an Electronic Stability Program (ESP) of a vehicle body and then transmitted to the TCU through a CAN bus; the signals of the shift paddles are sent to a Combination Switch Assembly (CSA) and then transmitted to the TCU, also via the CAN bus. The vehicle speed signal CAN be detected by a speed sensor (not shown) and also sent to the TCU through the CAN bus, and the vehicle movement direction signal CAN be detected by a transmission output shaft speed sensor (not shown) and also sent to the TCU through the CAN bus.
The following provides preferred gear shifting modes when the current gear is a forward gear, a reverse gear, a neutral gear, a parking gear, or a manual gear.
1. When the detected current gear is a parking gear:

when the second gear shifting input device and the brake pedal are pressed down, the gear of the vehicle is switched from the parking gear to a forward gear;
and when the first gear-shifting input device, the second gear-shifting input device and the brake pedal are treaded down, the gear of the vehicle is switched from the parking gear to the neutral gear.
2. When the detected current gear is the reverse gear:

In addition, if the second gear-shifting input device and the brake pedal are pressed, the received vehicle speed signal indicates that the vehicle speed is greater than the preset vehicle speed, and the vehicle movement direction signal indicates that the vehicle is moving backwards, the vehicle speed will be changed too much compared with the forward driving, so that the gear can not be shifted to the forward gear, and the driver may be recommended to decelerate (for example, press the brake pedal).
3. When the detected current gear is a forward gear:
when the signal that the electronic parking brake is pulled up is received and the received signal of the vehicle speed is that the vehicle speed is less than or equal to a preset vehicle speed (such as 2km/h, but not limited to), switching the gear position of the vehicle from the forward gear to the parking gear; in addition, if the vehicle speed is greater than the preset vehicle speed when the signal that the electronic parking brake is pulled up is received, the shift position to the parking position cannot be switched because the vehicle speed is too fast, and the driver may be recommended to decelerate (for example, to step on the brake pedal).

And when signals of the first gear-shifting input device and the second gear-shifting input device are received, the gear of the vehicle is switched from the forward gear to a manual gear.
4. When the detected current gear is neutral:
when the signal that the electronic parking brake is pulled up is received and the received signal of the vehicle speed is that the vehicle speed is less than or equal to a preset vehicle speed (such as 2km/h, but not limited to), switching the gear position of the vehicle from the neutral gear to a parking gear; in addition, if the vehicle speed is greater than the preset vehicle speed when the signal that the electronic parking brake is pulled up is received, the shift position to the parking position cannot be switched because the vehicle speed is too fast, and the driver may be recommended to decelerate (for example, to step on the brake pedal).
When the first gear shifting input device and the brake pedal are received and the received vehicle speed signal indicates that the vehicle speed is less than or equal to the preset vehicle speed, the gear of the vehicle is switched from the neutral gear to the reverse gear;
when the first gear shifting input device and the brake pedal are received and the received speed signal is that the speed is greater than the preset speed but the movement direction signal of the vehicle is backward movement, the gear of the vehicle is switched from the neutral gear to the reverse gear; in addition, if the first gear shifting input device and the brake pedal are received, the received vehicle speed signal is that the vehicle speed is greater than the preset vehicle speed, and the vehicle moving direction signal is forward movement, the vehicle speed is changed too much compared with backward movement, so that the gear can not be switched to the reverse gear, and the driver can be recommended to decelerate (for example, the brake pedal is stepped on).
When the second gear shifting input device and the brake pedal are received and the received vehicle speed signal is that the vehicle speed is less than or equal to the preset vehicle speed, the gear of the vehicle is switched from the neutral gear to a forward gear;
and when the second gear-shifting input device and the brake pedal are received and the received speed signal indicates that the speed is greater than the preset speed but the movement direction signal of the vehicle is forward movement, switching the gear of the vehicle from the neutral gear to a forward gear. In addition, if the second gear-shifting input device and the brake pedal are received, the received vehicle speed signal is that the vehicle speed is greater than the preset vehicle speed, and the vehicle moving direction signal is backward movement, and the vehicle speed is changed too much compared with forward movement, so that the gear can not be switched to the forward gear, and the driver can be recommended to decelerate (for example, the brake pedal is stepped on).
5. When the detected current gear is a manual gear:
when the signal that the electronic parking brake is pulled up is received and the received signal of the vehicle speed is that the vehicle speed is less than or equal to a preset vehicle speed (such as 2km/h, but not limited to), switching the gear position of the vehicle from the manual gear position to a parking gear position; in addition, if the vehicle speed is greater than the preset vehicle speed when the signal that the electronic parking brake is pulled up is received, the shift position to the parking position cannot be switched because the vehicle speed is too fast, and the driver may be recommended to decelerate (for example, to step on the brake pedal).
