Vehicle tachometer display
10336191 · 2019-07-02 · ·

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 fill in a region of the tachometer display, such as a sector between needles indicating current and desired angular velocities or most or all of a surface of the 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.

POWERTRAIN WITH ENGINE START FUNCTION USING RESETTABLE ENGINE SPEED PROFILE

A hybrid electric powertrain includes an electric machine delivering torque to an engine in an engine start event having initial cranking and transition phases. In response to a request for an engine start event, a controller commands delivery of the motor torque to the crankshaft. In the initial cranking phase the controller regulates crankshaft acceleration from zero speed up to a target cranking speed in a closed-loop manner via a predetermined fixed profile. In the transition phase, the crankshaft accelerates from the target cranking speed to a target idle speed using a feed-forward torque value blended, using a calibration table, from a predetermined engine drag torque to a reported engine torque. In the transition phase the controller periodically adjusts a speed trajectory of the crankshaft, with the magnitude and frequency of adjustment based on combustion of the engine and calibration of the feed-forward torque.
