A downhill target acceleration control system for a vehicle is provided, which includes the vehicle, a road grade sensor, an acceleration sensor, and a processor. The processor stores an acceleration target value, determines the mass of the vehicle, and detects whether a downhill acceleration of the vehicle exceeds the target value by more than a threshold amount. If so, the processor is configured to receive and implement a driver-initiated change to the downhill target acceleration value, without input from the accelerator or brake. Based on the downhill acceleration, the target value, and the mass, the processor generates a negative power train torque request to reduce the downhill acceleration of the vehicle. If the acceleration of the vehicle is then below the target acceleration by more than a second threshold amount, the processor reduces the negative power train torque request to increase the downhill acceleration of the vehicle.
