    摘要: Method and systems for automated anticipatory braking of a vehicle are provided. In one embodiment, the system comprises a vehicle accelerator movable between a maximum speed position and a minimum speed position, and a sensor configured to determine the rate of travel of the accelerator toward the minimum speed position. The system further comprises a controller configured to utilize the rate of travel of the accelerator to determine if a rapid braking condition is desired, and to provide a control signal to apply increased negative torque to the drive wheels of the vehicle prior to the user applying the vehicle brake. In some embodiments, driver history and/or other vehicle conditions are taken into account. In some embodiments, negative torque is applied via varying of valve timing, control of combustion chamber intake, control of exhaust backpressure, control of motor energy, and/or shifting of a transmission to a numerically higher speed ratio.
