A braking control system includes control circuitry configured to control first and second brakes in a vehicle. The control circuitry is configured to calculate a target braking force in accordance with the operation amount of a brake pedal by a driver, determine a first braking force and a second braking force based on the target braking force, and control each of the first and second brakes such that each of the determined braking forces is generated in the vehicle. The first and second braking forces are determined such that a sum of the first and second braking forces becomes the target braking force and a pitch behavior specified by a preset pitch behavior model occurs in the vehicle.

A vehicle includes an electric machine and a controller. The controller is programmed to, in response to releasing an accelerator pedal during a first driving scenario that is based on a first set of navigation data, increase regenerative braking torque of the electric machine to a first value. The controller is further programmed to, in response to releasing the accelerator pedal during a second driving scenario that is based on a second set of navigation data, increase the regenerative braking torque of the electric machine to a second value that is less than the first value.

A method is provided for controlling regenerative braking for a vehicle having a propulsion system, a motor, a transmission, and a clutch selectively coupling the motor to the transmission. The method includes estimating a future time at which the clutch disengages from the transmission. A rotational speed at which the clutch disengages from the transmission is calculated based on an idle speed of the propulsion system. A difference between a speed of the motor and the clutch disengage speed is monitored. A ramp down of regenerative torque on the motor is initiated when the difference is below a predetermined value and before the future clutch disengage time elapses.

A speed-command generating unit incorporated with an electric vehicle having a throttle module, a mechanical brake and a motor is disclosed and includes: a computation module for generating a computation value of a speed-command according to a throttle operating signal from the throttle module, a sensing module for detecting an activated status of the mechanical brake, a selecting module for providing a braking approach selecting signal, a trimming module for setting a trimming flag according to the activated status of the mechanical brake of last cycle, and a switching module connected therewith. The switching module generates different output values of the speed-command for the motor according to different foundations depending on the content of the trimming flag when the mechanical brake is inactivated in this cycle, and generates the output value according to the content of the braking approach selecting signal when the mechanical brake is activated in this cycle.

An electrical regeneration and vehicle deceleration control method includes operating an electrified powertrain in normal or maximum regeneration modes associated with lesser and greater electrical regeneration and vehicle deceleration rates, respectively, receiving an input from a driver of the vehicle indicative of a request to enable the maximum regeneration mode, detecting a status indicative of an availability of the maximum regeneration mode, and in response to receiving the request and based on the status of the maximum regeneration mode and a current vehicle deceleration rate: (i) operating the electrified powertrain in either the maximum regeneration mode or a normal regeneration mode, (ii) selectively outputting a message to the driver indicative of the status of the maximum regeneration mode, and (iii) selectively commanding a hydraulic brake system of the vehicle to generate brake force based on a driver-expected vehicle deceleration rate associated with the operative regeneration mode.
