Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In a first aspect, an embodiment of the present invention provides a shift position control apparatus.

Those skilled in the art will appreciate that the hardware configuration depicted in FIG. 1 is not intended to be limiting of the present invention, and may include more or less components than those shown, or some components in combination, or a different arrangement of components.
With continued reference to FIG. 1, memory 1005, which is one type of computer storage medium in FIG. 1, may include an operating system, a network communication module, a user interface module, and a gear control program. The processor 1001 may call a gear control program stored in the memory 1005, and execute the gear control method provided by the embodiment of the present invention.
In a second aspect, an embodiment of the present invention provides a gear control method.
Referring to fig. 2, fig. 2 is a flowchart illustrating a gear control method according to an embodiment of the present invention. As shown in fig. 2, the shift position control method includes:
step S10, initializing a basic gear and a user target gear of an electronic gear shifter ESM, and setting a whole vehicle gear based on the user target gear obtained by initialization;
in this embodiment, after the electronic shifter ESM is powered on, the basic gear of the ESM is in a to-be-initialized state, the basic gear of the ESM needs to be initialized according to a certain strategy, and after the basic gear of the ESM is initialized, the target gear of the user is initialized, and finally, the gear of the entire vehicle is set based on the target gear of the user obtained by initialization.
Further, in an embodiment, the step of initializing the basic gear and the user target gear of the electronic gear shifter ESM includes:
initializing a basic gear of an electronic gear shifter ESM; and synchronizing the user target gear to the initialized basic gear.
In this embodiment, after the basic gear of the electronic shift unit ESM is initialized, the target gear of the user is synchronized to the initialized basic gear. During a power-up cycle of the electronic gear selector ESM, the user target gear is synchronized only once with the basic gear.
Further, in an embodiment, the step of initializing the basic gear of the electronic gear shifter ESM includes:
if N continuous frames of whole vehicle gear messages are acquired within a preset time length and the N frames of whole vehicle gear messages correspond to the same gear, setting the basic gear of the ESM as the same gear corresponding to the N frames of whole vehicle gear messages, wherein N is a positive integer greater than or equal to 5.
In this embodiment, after the ESM is powered on, a timer is started, and within a timing duration (i.e., a preset duration, for example, 500ms) corresponding to the timer, if a stable finished vehicle gear can be detected, i.e., consecutive N frames of finished vehicle gear messages are obtained within the preset duration, and the N frames of finished vehicle gear messages correspond to the same gear, where N is a positive integer greater than or equal to 5, it is considered that a stable finished vehicle gear is detected, and a basic gear of the ESM is set to the same gear corresponding to the N frames of finished vehicle gear messages. For example, if 5 continuous frames of vehicle gear messages are acquired, and the 5 continuous frames of vehicle gear messages all correspond to the P gear, the basic gear of the ESM is set to the P gear.
Further, in an embodiment, the step of initializing the basic gear of the electronic gear shifter ESM further includes:
and if the continuous N frames of vehicle gear messages corresponding to the same gear are not acquired within the preset time, setting the basic gear of the electronic gear shifter ESM according to the vehicle speed.
In this embodiment, the entire vehicle gear message may not be acquired within the preset duration, or the continuous N frames of entire vehicle gear messages are acquired, but the N frames of entire vehicle gear messages do not correspond to the same gear, that is, the continuous N frames of entire vehicle gear messages corresponding to the same gear cannot be acquired within the preset duration, and the entire vehicle gear is considered to be in an unstable state. At this time, the automobile speed needs to be acquired, and the basic gear of the electronic gear shifter ESM is set according to the automobile speed.
Further, in an embodiment, the step of setting the basic gear of the electronic gear shift ESM according to the vehicle speed includes:
when the automobile speed is less than or equal to the preset speed, setting the basic gear of the electronic gear shifter ESM as a P gear; and when the automobile speed is greater than the preset automobile speed, setting the basic gear of the electronic gear shifter ESM as an N gear.
In the embodiment, when the automobile speed is less than or equal to the preset speed, the basic gear of the electronic gear shifter ESM is set to be the P gear; and when the automobile speed is greater than the preset automobile speed, setting the basic gear of the electronic gear shifter ESM as an N gear. The preset vehicle speed is set according to actual needs, for example, set to be 2 km/h.
Step S20, when effective gear shifting action is detected, determining a new user target gear according to the basic gear and the effective gear shifting action, and updating the gear of the whole vehicle based on the new user target gear;
in this embodiment, a shift standard is established based on the regulations and the personalized settings of the host factory, for example, a brake needs to be stepped on for switching between the P-gear and the D-gear. When the gear shifting action of the user meets the standard, the gear shifting action of the user is determined as an effective gear shifting action, when the effective gear shifting action is detected, a new user target gear is determined according to the basic gear and the effective gear shifting action, for example, the basic gear is a P gear, and if the effective gear shifting action is used as a brake and moves backwards for two steps, the new user target gear is determined as a D gear, so that the gear of the whole vehicle is updated to be the D gear based on the new user target gear.
For example, when a valid shift action is detected, and a new user target gear is determined to be a D gear, a D gear signal is sent to the TCU or the VCU (for a vehicle, the TCU is a new energy vehicle, and if the vehicle is a new energy vehicle, the VCU) through the CAN bus, so that the TCU or the VCU CAN set the gear of the whole vehicle to be the D gear.
It is easy to understand that when the gear shifting action is taken as an invalid gear shifting action, a gear shifting failure prompt is output, and the target gear of the user is kept unchanged.
And step S30, updating the basic gear according to the new vehicle gear.
In this embodiment, after the entire vehicle gear is updated, the basic gear is updated with the new entire vehicle gear.
Further, in an embodiment, the step of updating the basic gear according to the new vehicle gear includes:
when the gear shifter is in a steady-state position, reading a new whole vehicle gear; and synchronizing the basic gear to be a new finished automobile gear.
In this embodiment, when the user is operating the shifter (shift lever or shift knob or shift paddle), the shifter is in the steady state position, and at this moment, the ESM reads the latest entire vehicle gear according to a certain frequency, and synchronizes the basic gear as a new entire vehicle gear. Where the frequency is set according to the actual situation, e.g. read every 2 ms. It is easily understood that the basic gear remains when the shifter is in the unstable position.
In the embodiment, a basic gear and a user target gear of an electronic gear shifter ESM are initialized, and a whole vehicle gear is set based on the user target gear obtained by initialization; when effective gear shifting action is detected, determining a new user target gear according to the basic gear and the effective gear shifting action, and updating the gear of the whole vehicle based on the new user target gear; and updating the basic gear according to the new finished automobile gear. Through this embodiment, put forward the notion of ESM basic gear to confirm user's target gear based on basic gear and user operation, then formulate whole car gear with user's target gear, formulate basic gear with whole car gear at last again, thereby guarantee that the inside gear of ESM keeps unanimous with whole car gear, guaranteed promptly that the actual gear of vehicle accords with user's intention. The method is strong in realizability and universality and suitable for transmission vehicles and new energy vehicles.
Further, in an embodiment, the gear control method further includes:
if the continuous N frames of vehicle gear messages corresponding to the same gear are not obtained within the preset time, and the vehicle speed messages cannot be obtained after the preset time is exceeded, an ESM initialization failure prompt is output, and the failure reason is recorded in a snapshot mode.
In this embodiment, if the N frames of vehicle gear messages corresponding to the same gear are not obtained continuously within the preset time, and the vehicle speed message cannot be obtained after the preset time is exceeded, the basic gear of the ESM cannot be initialized. At this time, an ESM initialization failure prompt is output, and the failure reason is recorded in a snapshot form, so that the subsequent investigation on the specific reason of initialization failure is facilitated.
Referring to fig. 3, fig. 3 is a flowchart illustrating initialization of an ESM basic gear and a user target gear according to an embodiment.
As shown in fig. 3, after the ESM is powered on, the basic gear initialization and the target gear initialization are started. For basic gear initialization, starting a timer, and if the stable and effective external whole vehicle gear is detected within the time T, filling the stable and effective external whole vehicle gear to an ESM basic gear, so that the basic gear is successfully initialized; if the external whole vehicle gear is not detected to be stable and effective within the time T, an ESM basic gear active initialization process is started, specifically: detecting whether a vehicle speed signal exists and is effective; if so, when the vehicle speed is less than or equal to X, initializing the basic gear to be a P gear, and when the vehicle speed is greater than X, initializing the basic gear to be an N gear, so that the basic gear is initialized successfully; if not, the basic gear initialization fails, the ESM sends an initialization failure prompt to the normal state, and records a fault snapshot. For user target gear initialization, whether basic gear initialization is successful or not needs to be detected firstly, if so, the user target gear synchronizes the basic gear, so that the user target gear initialization is successful, response to user operation is started, and a gear message is sent outwards, and the user target gear does not respond to the user operation and does not send the gear message outwards during the initialization period.
In a third aspect, an embodiment of the present invention further provides a shift position control device.
