A vehicle includes a powertrain having an electric machine configured to power driven wheels, an accelerator pedal, and friction brakes. A vehicle controller is programmed to, with the vehicle being in a one-pedal driving mode: in response to a braking torque capacity of the powertrain exceeding a target braking torque that is based on a position of the accelerator pedal, command a torque, that is equal to the target braking torque, from the powertrain such that the vehicle is slowed using the powertrain without application of the friction brakes, and, in response to the braking torque capacity of the powertrain being less than the target braking torque, command torques from the powertrain and the friction brakes such that the target braking torque is satisfied and the vehicle is slowed using the powertrain and the friction brakes.

Vehicle braking controls and methods

A vehicle includes an accelerator pedal, an electric machine, and a controller. The electric machine is configured to propel and brake the vehicle according to a one-pedal driving operation. The controller is programmed to, in response to depressing the accelerator pedal, command a desired torque to the electric machine. The controller is further programmed to, adjust the desired torque based on a gradient of a road surface that the vehicle is positioned on. The controller is further programmed to, in response to movement of the electric machine in a direction that is opposite to a desired direction while the adjusted desired torque is being applied, increase the adjusted desired torque by a compensation torque such that movement of the electric machine transitions to the desired direction.

One-pedal drive system for a vehicle

Aggregating braking torque during one-pedal drive mode

A vehicle includes active grill shutters and a controller. The active grill shutters are configured to open to increase a drag on the vehicle and to close to decrease the drag on the vehicle. The controller is programmed to, in response to regenerative braking via an electric machine and an absence of friction braking, transition or maintain the active grill shutters to or in a closed position. The controller is further programmed to, in response to friction braking, transition or maintain the active grill shutters to or in the open position.

Braking control system for a hybrid or electric vehicle

A vehicle comprising, an accelerator pedal, a brake pedal, an electric machine, and a controller. The electric machine is configured to propel the vehicle and to brake the vehicle via regenerative braking. The controller is programmed to, in response to releasing the accelerator pedal, increase a regenerative braking torque of the electric machine to a first value. The controller is further programmed to, in response to depressing the brake pedal, increase the regenerative braking torque of the electric machine from the first value to a second value. The controller is further programmed to, in response to a speed of the vehicle decreasing to less than a first threshold, decrease the regenerative braking torque of the electric machine from the second value to the first value.
