In the case of starting on the ramp and parking, the hill-start assist system (HAS) ensures that the vehicle won't roll backward. This enhances driving ease. However, there are specific situations where dispersed driving electric vehicles cannot use the conventional hill-start technique. Therefore, a hill-start control approach appropriate for distributed driving electric vehicles is given in this study based on the pneumatic electronic parking brake system (EPB), in order to realize the vehicle's quick and steady ramp start. First, a dynamic allocation approach based on the front and rear axle loads is selected in terms of demand torque after analyzing the change in the vehicle's force during the ramp's initialization. Second, the hill-start control target is established using the vehicle's force analysis on the ramp, and the logic threshold control method is utilized to instantly match the actual pressure to the desired pressure. Then, a driving torque correction controller based on the sliding mode algorithm is created to stop driving wheels from slipping on rough roads, which would reduce the overall driving force and cause the car to roll back. Finally, the controller model, vehicle model, and pneumatic EPB system model were established using Matlab, Trucksim, and AMEsim for co-simulation verification. The simulation results demonstrate that the suggested control approach can keep the car from slipping in a variety of driving situations.
