Method and system to coach driver of manual transmission vehicle

摘要

A coaching system for drivers of vehicles monitors the power dissipation of a manual transmission clutch and, when the energy dissipated during an event is excessive, suggests modified driving technique. The system may monitor launch events, shift events, and steady state driving. The system may adjust the energy threshold at which a suggestion is provided based on vehicle weight or road gradient. The system may also adjust the energy threshold when an estimate of clutch temperature is elevated. The suggestion may be provided on a graphic display or may be provided verbally over a speaker. In some cases, the suggested may also be conveyed to a third party outside the vehicle.

主权项

1. A method of coaching a driver of a vehicle having a manual transmission comprising:
monitoring, in a controller, a clutch input speed, a clutch output speed, and a clutch torque; based on the input speed, output speed, and torque, estimating a clutch power dissipation; and in response to the power dissipation exceeding a power threshold for longer than a duration threshold, automatically outputting a suggested driving technique change to mitigate clutch degradation.
