Abstract
A system for controlling a component of a gear in a vehicle, especially a clutch, through a hydraulic transmission link. The system includes a transmission control unit and an engine control unit, whereby a loss in fluid in the transmission link can be detected or a hazardous situation caused by the potential for fluid loss is avoided, whereupon the engine and/or the transmission can be suitably controlled using the transmission control and/or engine control unit.
Claims18
A system for controlling a vehicle with a transmission component having a hydraulic transmission link, the system comprising:
- a transmission controller;
- and
- an engine controller, the engine and/or the transmission being controlled by the transmission controller and/or the engine controller so as to detect a fluid loss or to avoid a hazardous situation capable of occurring from a fluid loss in the hydraulic transmission link.
A method for controlling a vehicle having an automatic clutch and a controller for the clutch controlling the clutch via a fluid transmission link capable of leaking comprising the steps of:
- determining a situation of the vehicle where a leak in the fluid transmission link would be a hazardous situation, and
- turning off the engine or placing the transmission in neutral during the hazardous situation.
