In the embodiment of the invention, the target vehicle may be understood as a vehicle provided with an electronic shift system. For easy understanding, before the specific technical scheme of the embodiment of the present invention is described, an electronic gear shifting system is described by taking a target vehicle as an example of a dual clutch automatic transmission (Dual Clutch Transmission, DCT) model. Fig. 1 is a schematic diagram of an electronic gear shifting system in a certain dual clutch automatic transmission vehicle type. Referring to fig. 1, the electronic shift system includes: the gear shifting device comprises a gear shifter, a gear shifting actuator controller, a gear shifting actuator, a gearbox controller and a gearbox, and the gear shifting is realized through the actuator controlled by an electric signal. The gear shifting device is connected with the gear shifting actuator controller through a controller area network (Controller Area Network, CAN) bus, the gear shifting actuator controller is connected with the gear shifting box controller through the CAN bus, the gear shifting actuator controller is connected with the gear shifting actuator through a hard wire, the gear shifting box controller is connected with the gear shifting box through a hard wire, the gear shifting actuator is mechanically connected with the gear shifting box, and the functions of all parts in the electronic gear shifting system are specifically described below.
1. A gear shifter: the gear shifting device is used for acquiring gear shifting intention of a driver and sending position information of a gear shifting rod to a gear shifting actuator controller through a CAN bus, wherein the position information of the gear shifting rod comprises specific position information of the gear shifting rod and parking key information positioned on the gear shifting rod.

Example 1
Fig. 2 is a schematic flow chart of a method for initializing a vehicle gear signal according to an embodiment of the present invention, where the method may be applied to a case of implementing a gear shift of a gearbox without a gear sensor, and the method may be performed by an apparatus for initializing a vehicle gear signal, where the apparatus may be implemented by software and/or hardware, and may be configured in a terminal and/or a server to implement the method for initializing a vehicle gear signal according to the embodiment of the present invention.
As shown in fig. 1, the method of this embodiment may specifically include:
s110, determining actuator position information of a gear shifting actuator when a target trigger signal for triggering a gear shifting controller of a target vehicle to initialize is detected.
In the present embodiment, the target vehicle may be understood as a vehicle provided with an electronic shift system, and may be, for example, a DCT transmission vehicle type or the like. A shift controller may be understood as a gear controller in a target vehicle shift system for transmitting a shift command to drive a shift. Similarly, a shift actuator may be understood as a gear actuator in a target vehicle shift system for executing a shift command.
The target trigger signal may be understood as a signal for triggering a shift controller of the target vehicle to perform a specific operation, among others. In this embodiment, the target trigger signal may be used to trigger the shift controller of the target vehicle to perform an initialization operation. For example, the target trigger signal may include, but is not limited to, starting and powering up the target vehicle, or powering up the electronic gear shifting system of the target vehicle again after a short power-off due to a sudden failure during running, etc., which is not limited in this embodiment. The actuator position information is understood to be gear position information determined as a function of the angle at which the shift actuator is turned. By way of example, the actuator position information may include, but is not limited to, park position information, neutral position information, position information between park and neutral, and other information indicative of a gear position, and the like, to which the present embodiment is not limited. For example, the shift actuator indicates a park gear when rotated to the 0 degree position, a neutral gear when rotated to the 15 degree position, or the like.
In a specific implementation, when the electronic gear shifting system of the target vehicle detects a target trigger signal for triggering the gear shifting controller to perform an initialization operation, the gear shifting controller needs to first determine the position of the gear shifting actuator before the driver does not operate the gear shifting lever, so that various operations in a subsequent initialization process can be performed according to the position information of the gear shifting actuator.
It should be noted that, as described above, the shift actuator is an actuator mounted on the transmission for implementing a park shift and a neutral shift, so, in order to ensure that the target vehicle is in a safe driving state during the initialization process of the shift system, first, the actuator position information of the shift actuator needs to be determined, so that the initialization operation of the shift controller is further implemented based on the actuator position information determination.
S120, determining an initialization gear signal of the gear shifting controller according to the position information of the actuator.
In this embodiment, the initialization gear signal may be understood as a gear signal corresponding to a target gear to be reached by the shift controller after the initialization is completed. For example, the initialization gear signal may include, but is not limited to, a gear signal corresponding to a parking gear, a gear signal corresponding to a neutral gear, a gear signal corresponding to a forward gear, a gear signal corresponding to a reverse gear, and a gear signal corresponding to other gears, which is not limited in this embodiment.
In a specific implementation, when the gear shift controller needs to perform an initialization operation, firstly, the position information of an actuator of the gear shift actuator needs to be determined, and further, a gear signal corresponding to a target gear to be reached by the gear shift controller when the initialization is completed is determined according to the obtained position information of the actuator, so that a driver can adjust a current gear according to the determined initialization gear signal, and the target vehicle can be ensured to keep safe running in the initialization process of the electronic gear shift system.
The initialization gear signal of the shift controller may be determined directly by determining the initialization gear signal of the shift controller according to the gear information indicated by the actuator position information, or may be determined by combining other determination factors together based on the actuator position information. The direct determination of the initialization gear signal of the shift controller by means of the actuator position information may include the following two cases.
In this embodiment, optionally, determining the initialization gear signal of the shift controller according to the actuator position information includes: and if the position information of the actuator is the parking gear position, determining an initialization gear signal of the gear shifting controller as a gear signal corresponding to the parking gear.
Specifically, if in the initializing process of the electronic gear shifting system, when the position information of the actuator of the gear shifting actuator obtained by the gear shifting controller is the position information corresponding to the parking gear, it indicates that the output gear of the gearbox for controlling the gear shifting system is in a locked and stationary state, and in order to ensure the safety of the target vehicle and the driver, the initializing gear signal of the gear shifting controller needs to be determined as the gear signal corresponding to the parking gear, so that the running safety of the target vehicle can be improved.
Optionally, determining the initialization gear signal of the target vehicle according to the actuator position information includes: and if the position information of the actuator is invalid or lost, determining the initialization gear signal of the gear shifting controller as a gear signal corresponding to the invalid value.
The fact that the position information of the actuator is invalid or lost is understood to be that the signal is lost or invalid due to the failure of the electronic gear shifting system. For example, the causes that cause the actuator position information to be invalid or lost may include, but are not limited to, a shift controller failure, a shift actuator failure, a failure of communication between the shift controller and the shift actuator, or other failure conditions that may cause the actuator position information to be invalid or lost, etc., as the present embodiment is not limited.
Specifically, if the position information of the actuator acquired by the gear shifting controller is an invalid value or the signal of the gear shifting actuator is not acquired at all when the electronic gear shifting system is in the initializing process, the initializing gear signal of the gear shifting controller can be determined to be a gear signal corresponding to the invalid value, for example, the target gear can be displayed as an invalid directly on an instrument panel or other positions of the target vehicle, so that a driver can be prompted that the current vehicle is faulty and needs to be repaired in time.
According to the technical scheme, when the target trigger signal for triggering the gear shifting controller of the target vehicle to initialize is detected, the position information of the actuator of the gear shifting actuator is needed to be determined, and furthermore, the initialization gear signal of the gear shifting controller is determined according to the position information of the actuator, so that the problem that the initialization gear of the gear shifting controller cannot be determined when a gear shifting system is in an initialization process under the condition that a gear shifting sensor is not available in the prior art is solved, the running safety of the vehicle is guaranteed on the premise that the production cost is saved, and the user experience is improved.
Example two
Fig. 3 is a flow chart of an initialization method for a vehicle gear signal according to a second embodiment of the present invention, and the technical solution is further refined according to the present embodiment on the basis of the technical solution described above. In this embodiment, on the basis of any one of the optional technical solutions of the embodiments of the present invention, optionally, the determining, according to the position information of the actuator, an initialization gear signal of the target vehicle includes: if the actuator position information is a neutral position, an initialization gear signal of the shift controller is determined from a transmission gear signal of a transmission controller of the target vehicle.
Wherein, the technical terms identical to or corresponding to the above embodiments are not repeated herein. As shown in fig. 3, the method of this embodiment specifically includes the following steps:
s210, determining actuator position information of a gear shifting actuator when a target trigger signal for triggering a gear shifting controller of a target vehicle to initialize is detected.
S220, if the actuator position information is the neutral position, determining an initialization gear signal of the gear shifting controller according to the gear signal of the gear shifting controller of the target vehicle.
As previously described, the transmission controller may be a controller in an electronic shift system that implements reverse, neutral, and forward shift operations. The gear signal of the gearbox can be understood as the gear signal corresponding to the gear where the gearbox controller is located.
In a specific implementation, when it is detected that the gear shift controller of the target vehicle needs to perform an initializing operation, first, gear information corresponding to an actuator position of a gear shift actuator needs to be determined, and if the determined actuator position information is a position where a neutral gear is located, a transmission gear signal of the transmission controller needs to be further determined, so that the initializing gear signal of the gear shift controller can be determined according to the gear signal of the transmission.
In this embodiment, optionally, determining the initialization gear signal of the shift controller according to the gear signal of the gear controller of the target vehicle includes: if the transmission gear signal of the transmission controller of the target vehicle is a reverse gear, a neutral gear or a forward gear, the initialization gear signal of the shift controller is determined as the transmission gear signal.
Specifically, if the actuator position information of the shift actuator of the target vehicle is the neutral position, the initialization signal of the shift controller needs to be determined according to the gear signal of the transmission controller, and when the transmission gear signal is the reverse gear, the neutral gear, or the forward gear, the initialization gear of the shift controller of the target vehicle will also be determined as the corresponding reverse gear, the neutral gear, or the forward gear.
Optionally, determining the initialization gear signal of the shift controller according to the gear signal of the gear controller of the target vehicle includes: and if the acquired gearbox gear signal of the gearbox controller of the target vehicle is a parking gear signal, a gear return interval signal, an invalid value or the gearbox gear signal is not acquired, determining the initialization gear signal of the gear shifting controller as a gear signal corresponding to the neutral gear.
The transmission gear signal is a parking gear signal, which indicates that the gear in which the transmission controller is located is not a parking gear, but indicates that the shift controller obtains the parking gear signal of the shift actuator and then transmits the parking gear signal to the transmission controller.
The gear return interval signal can be understood as a position of the current gear between two gears, so that the gear signal acquired under the condition that the gearbox controller cannot judge a specific gear can not be judged.
Specifically, when it is determined that the actuator position information of the shift actuator of the target vehicle is the neutral position, it is necessary to determine an initialization gear signal of the shift controller according to the gear signal of the gearbox controller, and if the obtained gearbox gear signal is the park gear signal, the gear return interval signal, the invalid value, or the gearbox gear signal is not received, it is necessary to directly determine the initialization gear signal of the shift controller as the signal corresponding to the neutral gear, so that the target vehicle can be ensured to be in a safe driving state.
According to the technical scheme, when the target trigger signal for triggering the gear shifting controller of the target vehicle to initialize is detected, the position information of the actuator of the gear shifting actuator is needed to be determined, when the position information of the actuator is the neutral position, the initialization gear signal of the gear shifting controller is needed to be determined according to the gear shifting signal of the gear shifting controller, the problem that the target vehicle cannot judge the current actual gear caused by the fact that the initialization gear of the gear shifting controller cannot be determined specifically only according to the position information of the actuator when the gear shifting actuator is in the neutral position is solved, the initialization gear of the gear shifting controller is determined together by introducing the gear shifting information of the gear shifting controller, the driving safety of the vehicle is effectively improved, and the user experience is improved.
Example III
Fig. 4 is a flow chart of an initialization method for a vehicle gear signal according to a third embodiment of the present invention, and the technical solution is further refined in this embodiment based on the technical solution described above. In this embodiment, on the basis of any one of the optional technical solutions of the embodiments of the present invention, optionally, the determining, according to the position information of the actuator, an initialization gear signal of the target vehicle includes: if the actuator position information is in a reset region between the park position and the neutral position, a vehicle speed of the target vehicle is obtained, and an initialization gear signal of the target vehicle is determined according to the vehicle speed.
Wherein, the technical terms identical to or corresponding to the above embodiments are not repeated herein. As shown in fig. 4, the method of this embodiment specifically includes the following steps:
s310, determining actuator position information of a gear shifting actuator when a target trigger signal for triggering a gear shifting controller of a target vehicle to initialize is detected.
S320, if the actuator position information is in a reset area between the parking gear position and the neutral gear position, acquiring the vehicle speed of the target vehicle, and determining an initialization gear signal of the target vehicle according to the vehicle speed.
The return region between the parking position and the neutral position is understood to be the middle region between the position representing the parking position and the position representing the neutral position. Specifically, when the actuator position information is in the reset region, the specific running state of the current target vehicle cannot be determined according to the actuator position information, and thus the initialization gear signal of the gear shift controller cannot be determined, and therefore, other factors need to be introduced to determine the initialization signal of the gear shift controller of the target vehicle.
Optionally, determining an initialization gear signal of the shift controller according to the vehicle speed includes: and if the vehicle speed does not reach the preset first vehicle speed threshold value, determining an initialization gear signal of the gear shifting controller as a gear signal corresponding to the parking gear.
The first vehicle speed threshold may be a preset speed threshold for determining a driving state of the target vehicle. Illustratively, the first vehicle speed threshold may be 3 km/h, 5 km/h, 8 km/h, or the like, which is not limited by the present embodiment. For example, the first vehicle speed threshold may be 3 km/h.
Specifically, when the actuator position information is in the return region between the park position and the neutral position. The initialization gear signal of the gear shifting controller is needed to be truly determined according to the vehicle speed, when the vehicle speed of the target vehicle does not reach the preset first vehicle speed threshold value, the current target vehicle can be considered to be in a parking or approximately parking state, and therefore the initialization gear signal of the gear shifting controller can be determined to be a gear signal corresponding to a parking gear.
Optionally, determining an initialization gear signal of the shift controller according to the vehicle speed includes: and if the vehicle speed reaches a preset second vehicle speed threshold value, determining an initialization gear signal of the gear shifting controller as a gear signal corresponding to the neutral gear.
The second vehicle speed threshold may be a speed threshold set in advance for determining a running state of the target vehicle. Illustratively, the second vehicle speed threshold may be 3 km/h, 5 km/h, 8 km/h, or the like, which is not limited by the present embodiment.
It should be noted that, the "first" and "second" mentioned in this embodiment do not indicate any order, number or importance, but only the corresponding target subjects are different. For example, the "first vehicle speed threshold" and the "second vehicle speed threshold" may represent the same speed or may represent different speeds.
Specifically, when the actuator position information is in the reset region between the park position and the neutral position, the initialization gear signal of the shift controller needs to be determined according to the vehicle speed, and when the vehicle speed of the target vehicle reaches the preset second vehicle speed threshold value, the current target vehicle can be considered to be in the running state, so that the initialization gear signal of the shift controller can be determined as the neutral corresponding gear signal.
According to the technical scheme, when the target trigger signal for triggering the gear shifting controller of the target vehicle to initialize is detected, the position information of the actuator of the gear shifting actuator is needed to be determined, and when the position information of the actuator is in the reset area between the parking gear position and the neutral gear position, the actual position of the gear shifting actuator cannot be judged, so that the initialization gear signal of the gear shifting controller is needed to be finally determined according to the speed of the target vehicle, the problem that the initialization gear of the gear shifting controller cannot be determined according to the position information of the actuator in the reset area between two gears in the process of initializing the gear shifting controller is solved, the vehicle of the target vehicle is introduced to serve as the judgment condition of the initialization gear signal, the safety of the target vehicle in the initializing process is further improved, and the user experience is improved.
Example IV
The embodiment provides an optional example of an initializing method of a vehicle gear signal, the gear shift controller is powered on and initialized, and the gear shift controller sends a target gear of the gear shift controller after comprehensive judgment according to the actual position of a gear shift actuator, a gear signal value of a gearbox controller and the vehicle speed before a driver does not operate a gear shift lever.
The transmission controller receives only the actual gear of the shift controller and does not receive the target gear of the shift controller. The gear shift controller can send a P value only when the gear shift actuator is actually in the P gear (P cannot be sent out when the gear shift actuator is not in the P gear position); when the shift actuator is at a position other than P, the value of which position is actually given by which position the shift actuator is. The gear identification can be performed periodically, and in the non-P gear angle range, a previous cycle value is sent (because the non-P position cannot distinguish which gear is in the RND specifically, only a previous cycle value can be sent, and No Connection is sent at the No Connection (signal not representing a specific position).
Table 1 is an initialization signal value determining policy table in the initialization method of a vehicle gear signal provided by the embodiment of the present invention, and a specific signal value assignment manner may be shown in table 1.
TABLE 1
1. When the actuator position information of the shift actuator is the parking position, the initialization gear of the shift controller and the actual gear of the shift controller are directly determined as the parking gear irrespective of the transmission controller and the vehicle speed.
2. When the position information of the actuator of the gear shifting actuator is a neutral position, determining an initialization gear of the gear shifting controller and an actual gear of the gear shifting controller according to the gear information of the gear shifting controller;
1) When the transmission gear signal of the transmission controller is a reverse gear, a neutral gear or a forward gear, the initialization gear and the actual gear of the gear shifting controller can be correspondingly determined to be the reverse gear, the neutral gear or the forward gear;
2) When the gear signal of the gear box controller is a parking gear signal, a gear return interval signal, an invalid value or the gear box signal is not received, the initialization gear and the actual gear of the gear shifting controller are directly determined to be neutral gears.
3. When the actuator position information of the gear shifting actuator is in a reset area between a parking gear position and a neutral gear position, determining an initialization gear and a current gear of a gear shifting controller according to the vehicle speed;
1) When the vehicle speed is less than a preset speed threshold, the initialization gear and the actual gear of the gear shift controller can be determined to be parking gears, for example, the preset speed threshold can be 3 km/h;
and 2, when the vehicle speed is not less than a preset speed threshold value, determining the initialization gear and the current gear of the gear shifting controller as neutral gears.
4. When the function abnormality occurs in the gear shifting controller or the gear shifting actuator, and the position information of the actuator of the gear shifting actuator is an invalid value or a signal is lost, the initialization gear and the actual gear of the gear shifting controller are directly determined to be invalid values regardless of the speed of the gearbox controller and the vehicle.
It should be noted that, the relationship between the actual gear and the initialized gear of the shift controller may be understood that the actual gear is ultimately required to be adjusted to the initialized gear, and if the actual gear is inconsistent with the initialized gear, the actual gear is required to be adjusted to the initialized gear.
When the initial gear and the actual gear of the shift controller are determined according to the vehicle speed, when the initial gear of the shift controller is determined to be the parking gear and the shift actuator changes the gear to the parking gear, the actual gear of the shift controller is determined to be the parking gear when the shift actuator detects that the actual position of the shift actuator is the parking gear, and is determined in real time during the detection, and if the detection time-out has not detected that the actual position of the shift actuator is the parking gear, the actual gear of the shift controller is determined to be an invalid value. Similarly, when the initialization gear of the shift controller is determined to be neutral and the shift actuator shifts the gear to the gear other than the park gear, the shift controller determines the actual gear of the shift controller to be neutral when detecting that the actual position of the shift actuator is the non-park gear position, and determines in real time during the detection, and determines the actual gear of the shift controller to be an invalid value if the detection times out and the actual position of the shift actuator has not been detected to be the non-park gear position.
According to the technical scheme, when the target trigger signal for triggering the gear shifting controller of the target vehicle to initialize is detected, the position information of the actuator of the gear shifting actuator is needed to be determined, and furthermore, the initialization gear signal of the gear shifting controller is determined according to the position information of the actuator, so that the problem that the initialization gear of the gear shifting controller cannot be determined when a gear shifting system is in an initialization process under the condition that a gear shifting sensor is not available in the prior art is solved, the running safety of the vehicle is guaranteed on the premise that the production cost is saved, and the user experience is improved.
