The present invention provides a control which automatically elevates engine speed to a preselected value when the vehicle coasting in neutral above a preselected speed. In order to accomplish this objective, the engine controller is adapted to receive an actual gear ratio signal and a vehicle speed signal, If the vehicle is in neutral and engine speed is above a preselected threshold, the controller sets the desired engine speed to a preselected value which has been empirically determined to ensure sufficient transmission cooling and lubrication, Controlling to this speed also reduces transmission wear when the transmission is reengaged at high ground speeds. |
