  • Publication number: 20200079219
    Abstract: In a hybrid vehicle, brake force is divided between friction brakes and regenerative braking. When the friction brakes are wet, the delivered braking force may exceed the commanded braking force resulting in a poor transition from regenerative braking to friction braking. When wet friction brakes are detected, a controller allocates more of the total braking energy to friction brakes until a threshold quantity of energy has been dissipated in the friction brakes, thus drying the friction brakes over fewer braking events than otherwise.

  • Publication number: 20190337391
    Abstract: A hybrid electric vehicle having one or more controllers, at least two independently driven electric machines (EMs) that are each coupled to separate drive wheels, and controllers configured to generate a torque split ratio responsive to lateral acceleration and/or unequal friction coefficients detected during braking, and to generate electric power with the motors by regeneratively braking each wheel with unequal torques adjusted by the ratio, such that combined wheel braking torques do not exceed a total braking torque limit for the vehicle. In some configurations, the controller(s) generate the torque split ratio by a predetermined lookup table that maps a plurality of torque split ratios to lateral accelerations, the coefficients, and other parameters. Further arrangements include the controller(s) coupled with sensors that detect wheel slip and yaw rate, and responsive to a braking signal, the controller(s) disengage regenerative braking when the wheel slip and/or vehicle yaw are detected.

  • Patent number: 10399440
    Abstract: Methods and systems are provided for operating a hybrid vehicle during operating conditions where vehicle braking is requested. In one example, regenerative braking is permitted during conditions of wheel slip so that a greater portion of a vehicle's kinetic energy may be recovered and stored as electrical energy. Additionally, in some examples, the amount of regenerative braking is adjusted responsive to a torque of a differential clutch during wheel slip conditions.

  • Patent number: 10112613
    Abstract: A method of managing torque at a vehicle standstill includes outputting torque from a powertrain to satisfy a driver torque demand. The method also includes, in response to a nonzero torque demand resulting in vehicle standstill, applying a friction brake to maintain the vehicle standstill and substantially reducing output torque of the powertrain during friction brake application. The method further includes satisfying driver torque demand using the powertrain and releasing the friction brake in response to the driver torque demand deviating from the nonzero torque demand by more than a predetermined amount.

  • Patent number: 9919693
    Abstract: Driver braking performance feedback may be conveyed to a vehicle operator as a braking efficiency score using a vehicle display system. The display system may include a vehicle display for displaying a braking efficiency indicator or gauge corresponding to the braking efficiency score. The braking efficiency score may be based on a comparison of the total regenerative braking energy recaptured during at least one braking event to a either a maximum amount of braking energy that may be recaptured during the at least one braking event or an actual total braking energy expended during the at least one braking event. The braking efficiency score may be displayed upon the completion of a braking event or upon a completion of a trip including a plurality of braking events. The display may also convey a distance corresponding to a portion of a trip distance achieved through regenerative braking.
