Summary: | A vehicle controller determines likelihood of downshifting, such as by detecting braking and clutch disengagement. In response, the vehicle controller determines a desired angular velocity for the engine for a gear lower than a current gear. A tachometer display is updated to indicate the current angular velocity of the engine and the desired angular velocity. A difference between current and desired angular velocities is determined and a region of the tachometer display is filled, such as a sector between needles indicating current and desired angular velocities or most or all of a surface ofthe tachometer. The tachometer may be updated in the same manner according to a desired angular velocity in cases where the drive shifts into gear following coasting in neutral.
种车辆控制器例如通过检测制动和离合器的分离来确定降挡的可能性。作为响应,车辆控制器为低于当前挡位的挡位确定发动机的期望角速度。转速表显示器被更新以表明发动机的当前角速度和期望的角速度。确定当前角速度和期望角速度之间的差值并且填充转速表显示器的区域,例如表明当前和期望角速度的指针之间的扇区或转速表的大部分或全部表面。在空挡滑行后接合驱动挡的情况下,转速表可以根据期望角速度以相同的方式更新。 |
