Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of a method for identifying a gear of a manual gear according to an embodiment of the present invention. The embodiment is applicable to any vehicle equipped with a manual transmission. The gear identification method for the manual gear provided by the embodiment of the invention can be executed by the gear identification device for the manual gear provided by the embodiment of the invention, and the device can be realized in a software and/or hardware manner and is integrated in a vehicle executing the method.
Specifically, referring to fig. 1, the method specifically includes the following steps:
and S110, if the vehicle is detected to be in a forward gear state and a preset forward gear identification condition is met, calculating the transmission speed ratio of the vehicle in the current running process.
Specifically, a manual transmission is generally assembled on a manual transmission vehicle, a driver can switch the manual transmission gear of the vehicle in the driving process by operating a gear handle on the manual transmission gear, at the moment, a neutral gear, a reverse gear and forward gears under different gears exist on the manual transmission gear, and corresponding neutral switches and reverse switches can be set for the neutral gear and the reverse gear, so that the vehicle can timely know when being switched to the neutral gear or the reverse gear, but because the forward gears include more gears and corresponding gear switches are not set for each gear under the forward gear, the manual transmission gear adopted needs to be detected in real time in the driving process of the vehicle, the driver is assisted to timely know the current driving gear of the vehicle, and possible errors during subsequent gear shifting are avoided.
At this time, the embodiment firstly needs to detect whether the vehicle is in a forward gear state in real time according to the operation of a driver on the manual transmission of the vehicle, if the vehicle is detected to be in the forward gear state, whether the vehicle meets the forward gear identification condition needs to be further judged, the forward gear identification condition is a condition which is set in advance and can ensure that the vehicle normally runs in a forward gear state, if the vehicle further meets the preset forward gear identification condition, acquiring the respective rotating speeds of different transmission devices in the vehicle, which are set for the normal operation of the transmission system, in the current running process, and then calculating the transmission speed ratio of the vehicle in the current running process so as to screen out the manual gear corresponding to the speed ratio interval with which the transmission speed ratio accords under all gears of the forward gear subsequently, and ensuring the real-time accuracy of the identification of the manual gear.
For example, since a manual transmission vehicle may preset two transmission devices, namely a corresponding manual transmission case and an engine for controlling the vehicle to run, for a transmission system, in this embodiment, calculating a transmission speed ratio of the vehicle in the current running process may specifically include: and calculating the ratio of the engine speed of the vehicle in the current running process to the output shaft speed of the manual transmission as the transmission speed ratio.
Specifically, if it is detected that the vehicle is in the forward gear state and the preset forward gear identification condition is satisfied, the operating state of the engine of the vehicle in the current driving process is detected in real time, so as to obtain the corresponding engine speed, and meanwhile, the rotation frequency signal of the output shaft target disk on the manual gear transmission arranged on the vehicle is detected in real time, so as to determine the output shaft speed of the manual gear transmission according to the rotation frequency signal of the output shaft target disk on the manual gear transmission in the current driving process of the vehicle, and calculate the ratio of the engine speed and the output shaft speed of the manual gear transmission, which is used as the transmission speed ratio in the embodiment.
In addition, the determining whether the preset forward gear identification condition is met if the vehicle is detected to be in the forward gear state in the embodiment may further include: and if the vehicle is detected to be in a forward gear state and the preset forward gear identification condition is not met, identifying that the manual gear of the vehicle is an invalid gear.
Specifically, if the vehicle is detected to be in the forward gear state but the preset forward gear identification condition is not met, it is indicated that the vehicle cannot accurately identify the forward gear state under the current driving condition, so that the manual gear of the vehicle is identified as the invalid gear.
And S120, identifying the manual gear with the matched transmission speed ratio according to the speed ratio interval set for the manual gear gearbox on the vehicle under different gears.

Optionally, after the transmission speed ratio of the vehicle in the current driving process is obtained, the model of the manual transmission gear box assembled on the vehicle is firstly found out, then, the corresponding speed ratio interval preset for the manual transmission gear box under the model under different manual transmission gears is determined, the target speed ratio interval where the transmission speed ratio of the vehicle in the current driving process is located is selected from all the speed ratio intervals, then, the manual transmission gear matched with the manual transmission gear box under the target speed ratio interval is used as the manual transmission gear identified by the vehicle in the current driving process, and therefore the manual transmission gear of the vehicle in the driving process is accurately identified.
In addition, after the manual shift position of the vehicle is identified, in order to notify the driver in time so that the driver can accurately shift gears, the method may further include: displaying the manual gear through an instrument panel or other display equipment; the identified manual gear selected by the vehicle in the current driving process is displayed to the driver in time through an instrument panel or other display equipment on the vehicle, so that the driver can observe the identified manual gear at the current moment in real time, the driver is assisted to know the current driving gear in time, and therefore subsequent accurate gear shifting is carried out, and possible gear shifting errors are avoided.
According to the technical scheme, when the condition that the vehicle is in a forward gear state is detected and the preset forward gear identification condition is met, the transmission speed ratio of the vehicle in the current running process is calculated at first, the manual gear matched with the transmission speed ratio is determined according to the speed ratio interval set for the manual gear gearbox on the vehicle under different gears, and the manual gear is used as the manual gear identified by the vehicle under the current running process, so that the manual gear is accurately identified, a corresponding gear identification device is not required to be additionally added, the original mechanical structure of the vehicle is prevented from being changed, meanwhile, the next gear can be accurately converted according to the identified manual gear, the gear shifting fault is avoided, and the running reliability of the vehicle is improved.
