The disclosed systems, apparatus, and methods are provided for assisting shift of a manual transmission of a vehicle. An electronic control unit (ECU) receives a gear shift request from a shift selector. The gear shift request requests a shift of a gear to a desired position. The ECU eliminates the engine torque to substantially zero and indicates that the gear is ready to move to the neutral position. The ECU then determines whether the gear has moved to the neutral position. In response to determining that the gear has moved to the neutral position, the ECU adjusts the engine speed to match the transmission output speed and the gear ratio corresponding to the desired position, and indicates that the gear has been ready to shift to the desired position. The ECU then determines whether the gear has been switched to the desired position. In response to determining that the gear has shifted to the desired position, the ECU restores the engine torque.
提供了所公开的系统、装置和方法用于辅助车辆的手动变速器的换档。电子控制单元(ECU)从换档选择器接收档位变换请求。档位变换请求请求将档换到期望位置。ECU将发动机扭矩消除到基本为零,并指示档位已准备好移至空档位置。然后,ECU确定档位是否已移至空档位置。响应于确定档位已经移动到空档位置,ECU调节发动机速度以匹配与期望位置对应的传动比和变速器输出速度,并指示档位已准备好切换到期望位置。然后,ECU确定档位是否已切换到期望位置。响应于确定档位已经变换到期望位置,ECU恢复发动机扭矩。
