摘要： A method of optimizing steering and stability performance of a vehicle includes measuring a set of inertial data during a regenerative braking event (RBE), calculating a set of vehicle performance data using the inertial data, and comparing the performance data to calibrated threshold data to determine a maximum regenerative braking torque (RBT). The maximum RBT is automatically applied during the active RBE. The vehicle includes a chassis, an electric motor/generator for applying an RBT, a frictional braking system, chassis inertial sensors for measuring a set of chassis inertial data, and a controller having an algorithm for calculating a set of vehicle performance data using the chassis inertial data. The controller determines the maximum RBT by comparing the vehicle performance data to corresponding threshold data. The chassis inertial sensors can include accelerometers, a yaw rate sensor, a steering rate sensor, speed sensors, and/or a braking input sensor.

摘要： Methods and systems are provided for vehicle control during braking for vehicles having a transmission gear movable between at least a drive position and a neutral position. A wheel speed sensor measures a wheel speed of the wheel. A controller is coupled to the wheel speed sensor. The controller calculates a parameter using the wheel speed, and shifts the transmission gear from the drive position to the neutral position if the parameter exceeds a predetermined threshold. The parameter is indicative of a load on a component of the vehicle.

摘要： A method for operating a vehicle brake system during a wheel slip condition. According to an exemplary embodiment, the method involves receiving a requested brake torque, monitoring wheel slip, and if no wheel slip is detected then operating the vehicle brake system according to the requested brake torque. If, however, wheel slip is detected then the method may operate the vehicle brake system according to a modified brake torque that is less than the requested brake torque.

摘要： A method for adjusting braking in a vehicle having wheels and a regenerative braking system is provided. The method comprises the steps of providing regenerative braking torque for the vehicle via the regenerative braking system at a first level if a wheel slip of the vehicle is not present, and providing regenerative braking torque for the vehicle via the regenerative braking system at one of a plurality of modulated levels if the wheel slip is present. Each of the plurality of modulated levels is dependent on a magnitude, a location, or both, of the wheel slip. Each of the modulated levels is less than the first level.

摘要： A method minimizes a driveline vibration and reduces stopping distances in a hybrid electric vehicle (HEV) having a plurality of drive wheels, a friction braking system having antilock braking system (ABS) capability, and an electronically variable transmission (EVT) with two EVT modes. The method automatically shifts the EVT to a predetermined high speed/low torque EVT mode when the ABS is active and when a calibrated maximum deceleration rate is not exceeded. An HEV has a friction braking system with ABS capability and an EVT including a plurality of modes. A controller automatically activates the friction braking ABS in response to a threshold level of slip between the drive wheels and the road surface when the brake pedal is actuated. An algorithm automatically shifts the EVT into one of the high speed/low torque EVT modes when the ABS is activated and the calibrated maximum deceleration rate is not exceeded.

摘要： A method is directed to controlling a differential within an active antilock brake system. The method provides for receiving a secondary axle wheel speed, receiving a vehicle speed, determining a difference value between the vehicle speed and the secondary axle wheel speed, and activating the differential responsive to the difference value. The step of activating the differential responsive to the difference value may include steps for comparing the difference value to a threshold value and activating the differential based on the comparison. The step of activating the differential based on the comparison may include steps for determining a differential request value based on the comparison, activating the differential responsive to the differential request value when the differential request value is less than a maximum differential request value, and activating the differential responsive to the maximum differential request value when the differential request value exceeds the maximum differential request value.
