Problems solved by technology

[0003] At present, during the process of changing the calibration data of the electronic control unit (ECU) of the vehicle, if the starting operation of the starter is continued, the problem of wear of the starter drive wheel is prone to occur due to the abnormal operation of the starter; Secondly, when starting in a cold area, especially in the cold starting condition of minus ten degrees, the vehicle is difficult to start, and the driver will force the starter to start for a long time when starting the car. If the battery voltage is too low at this time, the life of the battery will be greatly reduced. In addition, the starter is often in working condition for a long time and frequently, or the engine is repeatedly started when the vehicle is idle or in gear, which will easily cause the starter to exceed the limit of use and be damaged, causing great inconvenience to the user

Abstract

Embodiments of the present invention provide a vehicle starter control method, device, and vehicle. The method includes: acquiring the current starter control calibration amount and the current battery voltage of the vehicle; based on the current starter control calibration amount and the current battery voltage, A relay control instruction is generated, the relay control instruction includes: a relay pull-in instruction and a relay disconnection instruction; based on the relay control instruction, the on-off state of the starter relay is controlled to control the vehicle starter. The embodiment of the present invention can effectively protect the starter and prevent damage to the starter of the vehicle under working conditions such as changes in the calibration data of the vehicle ECU and low battery voltage.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of starters, and in particular to a control method and device for a vehicle starter and a vehicle. Background technique [0002] The vehicle drives the flywheel of the engine to run from low speed to high speed through the operation of the starter, and at the same time the engine itself starts to start by compression ignition, and the starter exits normally to realize the vehicle starting process. In the whole process, detailed control such as the prerequisites for starting the starter, the exit timing of the starter, the timing of the second start, the starting frequency, and the time interval between two starts is particularly important. [0003] At present, during the process of changing the calibration data of the electronic control unit (ECU) of the vehicle, if the starting operation of the starter is continued, the problem of wear of the starter drive wheel is prone to occur due t...
