US 9,109,647 B2 · Device and method for control of a motor vehicle's propulsion

Abstract

A method, a device and a computer program for control of a motor vehicle's propulsion. When a clutch torque (Req T) is demanded by a driver activating of an accelerator pedal, the degree of closure (G) of the vehicle's clutch actuator is controlled by feedback on the basis of a monitored engine torque. There is at least one further consumer (290) of engine power in addition to propulsion. The method includes detecting (s410) activation of the at least one further consumer and, when such activation is detected, changing (s420) the feedback control to open control, whereby the degree of closure (G) of the vehicle's clutch actuator is based on a predetermined relationship between the degree of closure (G) and the clutch torque (Req T).

Dependent claims

A method for control of a motor vehicle's propulsion comprising:

demanding a degree of clutch torque of a clutch of the vehicle by activating an engine accelerator and producing engine torque to propel the vehicle;
controlling a degree of closure of a clutch actuator based on feedback based on a monitored engine torque of the vehicle;
selectively activating at least one further consumer of engine power in addition to propulsion of the vehicle;
detecting activation of the at least one further consumer;
and when such activation is detected, changing the feedback control to an open control, wherein the degree of closure of the vehicle's clutch actuator is based on a predetermined relationship between the degree of closure and the clutch torque, wherein the clutch torque is demanded by the driver by activation of the engine accelerator.
