Filing in context
The Engine Control Computer (ECU) is the most frequently cited component category in this archive, appearing in 5 of its 4,890 filings. This filing is one of 31 Honda notifications from 2014 in this archive. For scale, 288 of the 4,890 filings in this archive report a larger number of affected vehicles; the vehicles involved here were manufactured over a span of about 1 year.
Defect
Due to incorrect programming of the engine control computer (ECU), the estimated clutch friction characteristics learned by the ECU may deviate from the actual clutch friction characteristics. When this deviation is present and the engine is started by motor drive during EV travel mode, the motor may generate excessive drive force. As a result, vehicle speed may momentarily increase without driver intent.
Corrective action
On all vehicles, reprogram the engine control computer with the corrected/updated software.

状況
エンジン制御コンピュータ（ＥＣＵ）のプログラムが不適切なため、ＥＣＵが検知し学習しているクラッチ推定摩擦特性と実クラッチ摩擦特性がずれた状態で、ＥＶ走行モードでの走行中にモータ駆動でエンジンが始動した際、モータから過大な駆動力が発生することがある。そのため、運転者が意図せず車速が一瞬増加するおそれがある。
改善措置
全車両、エンジン制御コンピュータを対策プログラムに書き換える。
