Vehicle braking-to-braking-and-stopping control method and related device
ActiveCN119527274AGuaranteed not to slipImprove comfortExternal condition input parametersVehicle condition input parametersElectric machineryDrive motor
The invention discloses a method for controlling a vehicle from braking to braking and a related device, relates to the technical field of vehicle control, aims to solve the problem that the vehicle is easy to pitch and pause in the process from braking to braking, and realizes comfortable braking based on coordination of hydraulic braking control and driving motor torque control. Specifically, in the running process of a vehicle, a system calculates current vehicle parameters, environment parameters and user braking parameters in real time, and in the uphill working condition, on one hand, a driving motor is controlled to output driving torque to offset ramp resistance, and on the other hand, when the torque capacity of the motor is enough, the driving torque is controlled to offset ramp resistance. The pitching and jerking feeling in the braking process can be relieved through a large hydraulic braking pressure coefficient, and the braking comfort is improved. And when the torque capacity of the motor is insufficient, a smaller hydraulic braking pressure coefficient is used for ensuring that the vehicle is braked on the ramp without sliding. Therefore, according to the scheme, on the premise that it is guaranteed that the vehicle cannot slide during uphill braking, the comfort of braking to stop is improved.
