And if the current required gear is inconsistent with the output gear, the current required gear is inconsistent with the current response gear.
5. The gear shift control method according to claim 1, characterized in that, when the current required gear is inconsistent with a current response gear, before monitoring the duration of the gear inconsistency, the method further comprises:
acquiring a gear change state, and acquiring the gear request quantity, the gear switching request quantity and the unlocking P gear request quantity if the gear is changed;
if the number of the gear requests is zero, the gear is changed, and the current required gear is inconsistent with the current response gear;
If the number of the gear switching requests is zero, the gears are changed, and the current required gear is inconsistent with the current response gear;
and if the number of the unlocking P gears is zero, automatically unlocking the P gears, wherein the current required gear is inconsistent with the current response gear.
6. A gear shift control system, characterized by comprising:
The system comprises an acquisition module, a parking module and an automatic parking module, wherein the acquisition module is used for acquiring the speed, the current response gear and the gear request of a vehicle to be controlled, and the gear request comprises at least one of a user gear request and a gear request sent by the intelligent driving module or at least one of a user gear request and a gear request sent by the automatic parking module;
the processing module is used for determining a current required gear based on the gear request;
The monitoring module is used for monitoring the duration time of the inconsistent gear when the current required gear is inconsistent with the current response gear;
the control module is used for controlling the vehicle to be controlled to be switched to the P gear when the duration time is larger than a preset time threshold value and the vehicle speed is smaller than a preset lower vehicle speed threshold value; and when the duration time is larger than a preset time threshold value and the vehicle speed is larger than a preset upper vehicle speed threshold value, the vehicle to be controlled is controlled to be switched to N gear.
7. The gear shift control system according to claim 6, wherein,
When the number of the gear requests is larger than 1, the processing module is used for judging the priority sequence of each gear request according to the preset gear request priority and determining the current required gear according to the priority sequence;
And when the number of the gear requests is 1, the processing module is used for determining the gear requests as the current required gear.
8. An electronic device, the electronic device comprising:
one or more processors;
Storage means for storing one or more programs that, when executed by the one or more processors, cause the electronic device to implement the gear shift control method according to any one of claims 1-5.
9. A computer-readable storage medium, having stored thereon a computer program which, when executed by a processor of a computer, causes the computer to execute the gear shift control method according to any one of claims 1 to 5.
