The present invention relates to the technical field of vehicle control, and discloses a vehicle start control method, device, equipment and storage medium. The method includes: controlling the engine to increase the speed from the current start speed to the start target speed with a speed increase slope, and controlling the clutch to use the clutch The torque rising slope increases from the current clutch starting torque to the clutch target torque, controls the engine to increase from the engine starting torque to the engine desired torque with the engine torque rising slope, and maintains the engine to the starting target speed and engine desired speed based on the clutch target torque through the PID control algorithm torque to achieve vehicle launch control. By increasing the current starting speed, the current clutch starting torque and the starting torque of the engine synergistically with a fixed slope, combined with the PID control algorithm to stabilize the engine speed, the vehicle can be started smoothly, and the clutch during the vehicle starting process is reduced. The frictional heat generated by the friction prolongs the life of the clutch.
Description
technical field [0001] The present invention relates to the technical field of vehicle control, in particular to a vehicle starting control method, device, equipment and storage medium. Background technique [0002] Vehicle starting refers to the process of the vehicle changing from stationary to moving. From the perspective of the driver's operation, there are two ways. One is to release the brake without stepping on the accelerator pedal, and the vehicle starts to move from stationary. This process is called peristalsis. ; One is to release the brake and step on the accelerator pedal, the vehicle starts to move from a standstill, this process is called starting. The control methods of the two methods are different. In the process of starting the vehicle, from the analysis of the drivability at the start of the vehicle, the factors that affect the drivability of the vehicle at the start include the start shock, responsiveness, dynamics, and speed fluctuations. And because ...
